Becoming the Mask

Everything About Fiction You Never Wanted to Know.

"He wears a mask, and his face grows to fit it."

George OrwellShooting an Elephant (1936)

The Mole or the Con Man takes on a fake identity in order to gain something: information, money, a safe place. As time progresses, he grows to love his new identity and the way people treat him. His new friends prove reliable and he is struck by the contrast. He might even fall in love with another person whom he is explicitly supposed to be taking advantage of. Either way, he wants to remain in his new identity forever. He is Becoming the Mask.


Sometimes the friendship or relationship will dissolve when The Mole lets their true identity slip. For extra irony, have it happen in the process of confessing their love. ("You're so wonderful, I can't believe I was just seducing you to get the location of your secure base... whoops, Did I Just Say That Out Loud?") The usual response to The Reveal is "Was It All a Lie?" Occasionally, they will test the waters with a Trial Balloon Question.

A more cynical subtrope is when the person is actually the Reverse Mole, but the temptation of The Dark Side gradually causes them to discard their initial good cause and become everything they originally despised. Or they grow to believe their own Masquerade a little too much and become a Stepford Smiler. Can be the result of a Secret Identity Identity crisis.

Contrast Beneath the Mask where the audience is only given a peek. Similar in style to Amnesiac Dissonance, but without amnesia. May involve Oblivious Guilt Slinging. Compare Secret Identity Identity, Fake Real Turn, and Going Native. If the character does not even respond to his old name anymore, that is That Man Is Dead. When a literal mask starts to change someone's personality, it's Evil Mask. Contrast Lost in Character, where a character who is a professional actor lives and breathes a role. Do not confuse with Becoming the Costume or Becoming the Boast. Some spoilers ahead. Has overlap with The Woman Wearing the Queenly Mask.

Examples of Becoming the Mask include:

Anime and Manga

  • Mazinger Z: Erika. She was a android built by Dr. Hell. However, she suffered from amnesia and had forgotten her origins. She genuinely believed she was a normal girl, and when she was told her true nature, she rejected it. And the end she helped The Hero Kouji and she died cause it.
  • Zero from Tenchi Muyo!. She ended up fusing with the person she was emulating.
  • The motivation of Captain Kuro in One Piece, who wanted to give up the life of piracy to become a normal (albeit rich) man. Not so much a Face Heel Turn considering how he wanted to do it, though... turns into a cruel subversion when he seems to consciously invoke this trope in a confrontation with the girl he intends to kill to make her drop her weapon
    • Sogeking, in the same series. This is a literal case of becoming the mask for Usopp, who undergoes a heavy personality shift when he dons the Sogeking mask. This leads to a funny exchange where the Usopp and Sogeking parts of his personality have an argument while he's trying to think of a plan.
    • This series actually has a running theme of declaring oneself to be something and then using that as a source of strength to follow through. Sogeking, Luffy, Don Krieg, etcetera
    • Nico Robin had originally planned to use the Straw Hats as a shield until they deemed her too dangerous to protect any longer, as she had with all of the groups she joined. However, after being accepted and loved by them as one of their own, she chose to give up her life for the sake of her crew by giving herself into the government that she had been running away from her whole life. Of course, this didn't stop the Straw Hats from trying to save her despite her claiming she wanted to die; however, upon realizing that they would stick by her no matter what, she claimed that she wanted to stay in their crew forever and sail the seas with them.
      • Note that she still tried to deny, right up to the breaking point. The Straw Hats were already in the middle of The Government's stronghold (Luffy himself had personally wrecked over 1000 rank and file soldiers, Roaring Rampage of Revenge style. But then, he's Luffy. He's either in Idiot Hero mode or Roaring Rampage of Insert Emotion Here). So Robin STILL tries to talk them out of it. Luffy insists that they're going to rescue her anyway, and then she can leave the Straw Hat Pirates if she wants. And then... Tear Jerker ensues. Robin's tears, specifically, in a moment of Not So Stoic. Also, Pirate on Elite Assassin Team action.
    • Nami as well. She had only intended to use Luffy for all he was worth before leaving. But the longer she stayed with them, she grew to like being part of the Straw Hats (especially compared to her experiences with Arlong). Eventually, she betrayed them and cheerfully took off with Going Merry. But when on her own, she broke down and cried.
  • Mami in Sister Princess is a spy charged with disrupting the reunion of Wataru and his sisters, pretending to be another sister; at the climax of the series, she is the one who takes the action necessary to keep the family together, rejecting her own real brother—the mastermind of the scheme—to beg Wataru to come back home.
  • Played with in Irresponsible Captain Tylor. Tylor finds out Harumi is a Raalgon spy early on, but makes the decision to keep it between them and trust her despite her inevitable betrayal—something that completely confuses her. It's explicitly because of this response that Harumi begins having second thoughts that leads her to an official Heel Face Turn.
  • Kurama of Yu Yu Hakusho was a kitsune before he died and inhabited the body of an unborn human child. He planned to run away from his human "mother" Shiori Minamino when his demonic powers returned, but realized that he loved her too much to leave.
  • In Shugo Chara, Mr. Nikaidou is a spy for Easter who infiltrates the school. While he has no compunctions with backstabbing the heroes whatsoever, he is eventually defeated, and following the ensuing Defeat Means Friendship he immediately goes back to the school, performing the role he was using as his guise with no-one the wiser.
  • Subverted, deconstructed and played with in Code Geass.
    • Never one to be content with mediocrity, Lelouch vi Britannia wore and became not one, but two different masks through the series' run, one being Zero and the other being Lelouch Lamperouge.
      • Lelouch arguably believed in many of the ideals that he used Zero to represent but was too cynical to admit to himself. But with Nunnally becoming Viceroy in Area 11, being told by Kallen to keep deceiving her and the Black Knights as Zero, and by Suzaku to make his lies come true, he eventually embraces the mask... and in true, ironic Code Geass style, never more so than when he seemingly discards all ideals and becomes the Big Bad.
      • Between the two seasons, Lelouch is brainwashed into becoming Lelouch Lamperouge, the ordinary if highly intelligent high school student. Except that he's still disaffected with society and only superficially apathetic to the dreary, distasteful reality of Britannian domination.
    • Rolo, with each passing day, grows more comfortable in his role, until finally he dies for his “brother’s” sake.
    • While Villeta Nu only masqueraded as Ohgi's lover shortly before shooting him (thanks to Identity Amnesia), their past relationship was used to blackmail Villeta into siding with the Black Knights in R2, until the entire political lay of the land had been so thoroughly messed up that the blackmail was rendered moot, but at which point she didn't have to be blackmailed anymore to finally and fully join Oughi and the Black Knights.
  • A variant of the trope was done in the eighth Suzumiya Haruhi light novel: The Student Council President installed by Koizumi's Organization was supposed to act as a stereotypical arrogant, scheming leader of the Absurdly Powerful Student Council purely to serve as an opponent to keep Haruhi from getting bored (since her boredom can lead to bad things happening). In the ninth novel, however, the president seems to be slipping into the act subconsciously quite often. He even comments that he sometimes forgets which part of him is the "real" him.
  • In D Gray Man, Lavi is a successor to the Bookman lineage, who only joined the Black Order to record the war. However, as the years passed, he got more and more into the role of an exorcist, and is visibly angry when Bookman tells him he's not really a part of the Order, and that he's only there because it's convenient. His issues with Becoming the Mask are actually what Little Miss Badass Road Kamelot uses to "destroy his heart".
  • In Superior, the Big Bad female lead feigns hopelessness to gain the hero's trust and kill him. A few days later she realises she has a huge crush on him.
  • Between Tsukihime and Melty Blood, Meido Kohaku goes from sinister Chessmaster with no emotions who is planning the downfall of the Tohno family through drugging them; to really being the lovable goofball she pretends to be; who possibly makes robots and rides around on a broom in her spare time.
    • Note, however, that the robots and broom-riding may have been influenced by Tatari, and she's STILL trying to play everyone like saps. She's just more...nice...about it.
    • In Hisui's route it's revealed that she was becoming the mask, she just followed through on her plan anyway because she had no idea what else to do. In her own route, the mask starts to crack when Shiki pays attention to her and she reveals she honestly has no idea how she really feels anymore, so she leaves for a little while and becomes/reverts back to a very sweet, kind person.
  • Used quite positively in Haibane Renmei. Reki originally acted nice and supporting towards everybody solely to earn a quick salvation for her troubles, but as time went by and no Day of Flight came, it slowly became her true identity, as she finally realized in the final episode, allowing her to Ascend to a Higher Plane of Existence. This does not just come out of nowhere—some claim that it is the way Christian salvation is supposed to work; though like most aspects of Christianity, there are several other schools of thought.
  • Yukino Miyazawa. Her public mask which she created soon after she started school, was designed to elicit praise from those people around her. Playing the role of the perfect girl was so stressful that she had to unwind by turning into a slob at home. When Arima discovered her secret and blackmailed her, keeping her mask on became so uncomfortable that when she and Arima feel in love, she decided to throw her mask away, only to slowly discover that she acted perfect for so long that a lot of her mask persona became part of her true nature.
    • Arima also wore a mask of perfection but unlike Yukino, he never took his off, because he feared that his true nature was so awful that everyone would reject him if he took it off.
  • Happens to the fake Asuna, Shiori, in Mahou Sensei Negima. While her Signum Bioregens supposedly makes her more-or-less a sleeper agent (which is in and of itself a subversion of this trope) with added control (she can apparently switch at will), Shiori is in danger of merging with Asuna's personality if she falls in love while disguised. Infiltrating a group held together by a Chick Magnet might not have been the best of ideas...
    • Also appears to have happened to Governor-General Kurt Godel, who was unambiguously heroic 20 years ago. In the meantime, he infiltrated the corrupt senate, to find out more about and stop their villainy. He has since taken on many more villainous characteristics, such as being a Smug Snake and exhibiting Fantastic Racism to an incredible degree.
  • Lyle Dylandy in Gundam 00. He joins Celestial Being mostly as a Kataron Double Agent, but in the end, he becomes a full-fledged Gundam Meister like his deceased twin brother, Neil.
    • It has more to do with the First Law of Resurrection and the commercial success of Lockon (and the contract of the voice actors) than with a change of mentality.
    • Also Anew Returner. She's The Mole, but falls in love with Lyle. In the end, she attempts to return to him and Celestial Being, but is controlled by Ribbons into attacking Lyle, forcing Setsuna to kill her.
  • Flay Alster in Gundam SEED. She pretended to love Kira because she wanted to have revenge against him for her dad's death, which he caused indirectly, but ended up loving him for real.
  • Katejina Loos in Victory Gundam is effectively kidnapped by the Zanscare early on. At that point, she comes up with the idea of getting close to them and becoming a spy for the League Militaire. Whether or not that would have been possible ends up being beside the point, as she slowly (or maybe a little too suddenly) becomes an actual enemy pilot and a total zealot by the end.
  • In Ranma ½, Ryoga initially allowed Akane to cuddle and sleep with his cursed animal form, as a way to piss off her fiance Ranma. It backfired massively when Ryoga actually fell in love with Akane since she was so kind to his animal form, but had already doomed his chances by sleeping in her bed without her knowing it. Ouch.
  • Contractor Shihoko from Darker than Black started up a relationship with Huang sometime in the past as part of a Syndicate mission. While she didn't let any feelings get in the way of the original plan, they did spark some uncharacteristic pity that lead her to pull some strings and give Huang the opportunity to join the Syndicate himself as an alternative to memory erasure.
    • Also the cult leader Alma in the same episode. She started out as a typically ruthless Contractor and started the Friends of the Gate as a way of hiding from Contractor-hunting humans and keeping abreast of information about the Gate. Over time, because of the faithful worshipers, she began to believe in peaceful coexistence and genuinely became the spiritual leader she pretended to be. Totally against Contractor stereotype, she was happy to bear the terrible price of using her powers (rapid aging and debilitating health) so that she could appear young before her followers, and also considered it a way to atone for her past actions.
  • The titular running back of Eyeshield 21 undergoes this, taking on such a title which and becoming the "Hero of Notre Dame." The more the series progresses, the more he realizes how important that name really is and how people's dreams are relying on his lightspeed runs. And of course, this leads to problems when he meets the real Eyeshield 21...s and has to fight for his title.
    • Ironically his ultimate opponent is not someone who is vying for the title, but someone whom already surpassed everyone whom has taken up that title.
  • Stewart of Sonic X was a government agent assigned to investigate Sonic and the other animals. As it turned out, while he shows himself capable as an agent, he's really good at, and really likes, being a teacher. And occasionally a Badass Teacher.
  • Michelle from Mobile Suit Gundam is sent to spy on the White Base. She falls for a guy in the crew, Kai, and tries to help him instead. And then, she dies.
  • Pretty Cure loves this trope. Kiriya, the Kiryuu twins, Setsuna and Siren each pretended to be ordinary schoolkids in order to get close to the respective series' heroines and undermine their efforts. Inevitably, their interactions with the Cures expose them to the Power of Friendship and lead to a Heel Face Turn by the end.
  • In Tantei Gakuen Q, Ryu was supposed to be The Mole and infiltrate the DDS, but as time passed he discovered what friendship really was and grew fond of his partners for real.
  • In Bleach, this might have happened to Ichimaru Gin. He started out as a sweet kid who would go out of his way to help out his only friend and fellow orphan Matsumoto Rangiku. After Rangiku was brutalized by Aizen's men, Gin decided to worm his way into Aizen's trust in a bid to kill him. The first thing he did was kill one of the men responsible and take his place in Aizen's squad. Things just got worse from there. After spending decades acting the part of a scheming and bloodthirsty Smug Snake that someone like Aizen would want as a second-in-command, Gin pretty much became one for real though he never lost sight of his original goal. The only times he drops the mask and shows signs of his past self are the times he is forced to confront Rangiku.
  • In the manhwa Aflame Inferno, creatures called Tedlars can only interact with the human world by taking over a human's body, subsequently killing the human doing so. As the Tedlars usually have to live the same life the possessed humans do to avoid detection (not to mention they have access to all the humans' memories), it's quite possible that they become the human they took over themselves. However, usually Tedlars don't stay too long in one body, avoiding this.
  • In episode 18 of A Certain Magical Index, the guy who was hitting on Mikoto turns out to be a shapeshifting assassin assigned to kill her. He fell in love with her for real, so he decided to protect her from his colleagues, but murder Touma and get rid of his potential romantic rival. After Touma defeats him and a steel girder falls on him, he begs Touma to protect her as well.
  • Possible example in Shinigami from Soul Eater. He tells Asura that he took on his current silly appearance and demeanor to avoid scaring the children he wanted to recruit to his school, but that he 'got used' to it. The odd flashbacks depict him as far more ruthless and direct in his dealings with his enemies, although this may be due to the fact that he was free to do as he pleased rather than (as now) leave it all to humans. However he's not become so much Lighter and Softer that he can't get dangerous when needed. May have something to do with his being an Eldritch Abomination and how he chose to deal with it.
  • Possibly Uzumaki Naruto, who acted happy-go-lucky and goofy in order to attract attention, and never seemed to stop.
    • This also happened to Sai. Getting trained as an emotionless assassin left him more than a little vulnerable to a certain goofy hero. In a darker variant, this is Kabuto's backstory. He had pretty much the same upbringing as Sai and spent almost his entire life going undercover in various nations. By the end of it, he's not really sure who he is. When he breaks down, the village stops trusting him, he loses his only purpose in life, and ends up crazy.
  • In Bakugan: Gundalian Invaders, Ren was sent by the Gundalians to get the Battle Brawlers to join them in the guise that they were the innocent party in their war. However, after experiencing their friendship and eventually realizing that the king he served was a Complete Monster who didn't care about him, he did a Heel Face Turn and joined the Brawlers in the battle against his own kind.
  • In Tsubasa Reservoir Chronicle, it is revealed that Fai has secretly been working as a mole for Fei Wong in an attempt to resurrect his twin brother and has been misleading the group the entire time. However, he eventually develops a genuine affection for his comrades and undergoes a Heel Face Turn just prior to the reveal.
  • Played with in Special A. Megumi tries to distract Yahiro (the closest thing the early chapters have to a Big Bad) so that he won't interfere with Akira and Tadashi's burgeoning relationship. She does so by pretending to like him. Yahiro sees right through the mask, but goes along with it just to screw with her. In the process they end up actually falling for each other.
  • Fullmetal Alchemist has this with some of the homunculi. For instance, Pride is, as true to his name, totally bereft of compassion for any human being in the world... except for his foster mother, Mrs. Bradley, who tended dearly to him after he was hit by a car (not knowing he was a homunculus, nor about the near-immortality that comes with the territory). Doesn't mean he has any hesitation to sacrificing her along with the rest of the entire country in Father's plans, of course, but at the end of it all, he's the only homunculus left - having his Philosopher's Stone eradicated, but spared from death, by Edward Elric - and he gets grow up from scratch under her care. Wrath also shows compassion for the same woman given that she's his wife, but he doesn't have to put forth quite as much of an act as Pride does.
  • Yukki and Yuno in Mirai Nikki. Both of them were faking their love and using each other. Yukki used Yuno for protection and Yuno used Yukki for an emotional crutch. But over time the fake aspect became less and less fake and more like genuine love.

Comic Books

  • Batman himself: Bruce Wayne is now merely Batman in disguise and not the reverse, and even his subconscious calls him Batman, as seen in Batman Beyond. Like everything with Batman, how much this is true varies from writer to writer.
    • Summarized in the novelization of Knightfall, Alfred explains to Tim Drake that Batman uses the cowl to become a different personality, hearkening back to primitive beliefs that wearing the mask of a god is to literally become that god.

(Batman puts his mask on)
Bane: Stop hiding.
Batman: I'm not hiding. I'm becoming.

    • By now, he's gone so far that in Batman Inc #3, El Gaucho even remarks "Why the hell is Batman masquerading as Bruce Wayne, anyway? I've met Bruce Wayne and you don't fool me."
      • Ok, Bruce Wayne DID have a doppelganger (Tommy Elliot who's performed surgery on himself) but considering most major villains know his identity by now, plus the entire world know who's financing the Batman, the "Bruce Wayne" persona seems more like a hobby or souvenir he keeps for old times' sake.
    • There was also a three-part story in which Batman Became A Completely Different Mask; his undercover identity of Matches Malone. In "Close Before Striking", the real Matches Malone returns to Gotham, and gets shot by Scarface's gang, since Scarface has concluded that Malone is in cahoots with Batman. As Batman blames himself for this, he spends more time in his Matches identity, and both Bruce Wayne and Batman start adopting Matches's mannerisms and attitude. Nightwing is able to snap him out of it before he kills the Ventriliquist.
    • Batman probably keeps the Bruce Wayne persona because it's the last little bit of humanity he has left. In Bruce Wayne: Fugitive, he tells the rest of the Bat-family that he's dumping the Bruce Wayne identity to be Batman 24/7, seeing it as a liability. Nightwing, in particular, doesn't take that well and goes at it with him. It takes encounters with both Superman and Catwoman to realize that he kinda does need Bruce Wayne.
    • In some incarnations, becoming the mask may be what led Dr. Harleen Quinzel to become Harley Quinn. In her origin story, Mad Love, the possibility was brought up that she interned at Arkham Asylum to cash in on the infamy of its highly abnormal inmate body. Ultimately, she really does end up giving a damn about a certain patient.
  • From the Marvel Universe, we have the Thunderbolts, who were originally the newest incarnation of the Masters of Evil, posing as superheroes to win the public's trust while the major superheroes were apparently dead for a year. Their leader, Baron Zemo, eventually leaked their true identities to try to avert a Heel Face Turn before he could Take Over the World. It didn't work; the majority of the team defeated him, and tried—for various reasons—to actually become heroes. To the best of their moral abilities, anyway.
    • Only the first incarnation of the Thunderbolts counts as this. During Civil War the new Thunderbolts team was no longer "Reformed villains trying to actually be the heroes they'd originally pretended to be" and was instead "a bunch of violent thugs we stuck mind control chips into so we could use them for black ops" who they put under the direction of Norman Osborn and by Dark Reign had morphed into "Norman Osborn's especially vicious group of thugs because the Dark Avengers weren't bad enough."
    • The Heroic Age incarnation, on the other hand, is a specific attempt by the Avengers to induce this. They're using incarcerated supervillains to do good in the hopes that they'll start liking it, and then try to redeem themselves.
  • Interestingly used in Lucifer, where a shapeshifter is trapped in the form of a grieving father (whom it had killed to assume his shape, to try (and apparently succeed) at killing his daughter) and gradually becomes more the grieving father than the ancient shapeshifter from before the universe. This doesn't seem come about entirely honestly, though—much of the father's mentality seems to be forced onto the shapeshifter by the same magic that traps it in his form.
  • Walter Kovacs from Watchmen, a formerly abused but relatively normal superhero, takes on the persona of his alter ego Rorschach after an event of intense psychological trauma, becoming a Principles Zealot in the process.
    • Rorschach later describes the early years of his hero career as "I wasn't Rorschach then. Then I was just Kovacs. Kovacs pretending to be Rorschach". During his bail hearing he refused to respond to anything other than "Rorschach". He also refers to his mask as his face, and once referred to removing it as "removing the skin from my head". He's kinda sensitive about it.
    • "It was Kovacs who closed his eyes. It was Rorschach who opened them again." If that doesn't define this trope, nothing does.
    • It was portrayed wonderfully with the art too, when the reader sees Rorschach in the past, he stands differently and looks odd compared to the Rorschach we know in the present. There's something very human about him that adds a quiet tragedy to the man we know now.
  • Happened several times to the Skrull impostor(s) posing as Hank Pym during the Secret Invasion. Apparently a side-effect of the enhanced shape shifting they were using to escape detection. One issue revealed that they went through no less than 4 different Skrulls who each kept trying to defect once they settled into the role.
  • The Vertigo Comics version of Human Target written by Peter Milligan was all about this. The main character, Christopher Chance, was so good at imitating the people he was meant to protect that he needed post-hypnotic triggers to resume his "normal" personality.
  • Marvel's first Captain Marvel was a Kree soldier named Mar-vell, who came to Earth to spy on humanity. He eventually came over to Earth's side for real.
  • Magica De Spell goes through this in the Donald Duck story "Date with a Munchkin" by Kari Korhonen, where she kidnaps Daisy Duck and takes her place in order to get close to Scrooge McDuck's Number One Dime. During her time as Daisy, she receives Donald's affection for Daisy and takes a liking to their romance. (It helps that she's accidentally also dosed herself with the Love Potion she's using to forestall Donald's suspicions.) It culminates in a Duckburg ball where Magica originally intended to steal the dime, but chooses not to leave Donald's side. However, Daisy has escaped her restraints and crashes the ball, confronting Magica. When Donald takes Magica's side, believing that she's the real Daisy, Magica ends her illusion and flees the scene rather than break Daisy's heart. She later reflects that although she didn't manage the theft, she has experienced "a new feeling," and maybe that's worth something.
    • Magica manages it again in "A Gal For Gladstone": she hexes away Gladstone Gander's luck so he'll have to work for Uncle Scrooge, then disguises herself as a wholesome girl and seduces him to get close to the dime. She's genuinely touched by his devotion, though, and ends up giving up her chance at the dime in order to save his life.
  • Punch/Counterpunch in Dreamwave's Transformers Generation 1 comics. Punch is an Autobot spy sent deep undercover into the Decepticon ranks as counterintelligence expert Counterpunch. However, in developing Counterpunch's "character" and establishing him as a dedicated Decepticon, Punch may have caused an entirely new personality to develop within him; Lately, he's been having blackouts as Counterpunch and is unable to account for his whereabouts or activities, though he suspects Counterpunch is asserting himself and doing his job.
  • In the Sonic X comic book, Dr. Eggman disguises himself as the heroic wrestler El Gran Gordo to earn extra cash, but soon finds he likes being praised and adored by his fans. This leads him to almost pull a Heel Face Turn, and even after going back to villainy, he later returns to being El Gran Gordo for the thrills, fame, and loving fanbase. He also pummels a wrestler about twice his size, and considering how big Eggman was to begin with, that's quite a feat.
  • The Silver Age of Comic Books Superman had a story in which Clark Kent tries to prevent the demolition of his old home. Pete Ross assumes it's because he's afraid the workers will find something that'll give away his secret identity, but it's really because of Supes' sentimentality. Pete's last line is pretty much the trope. (Remember, this is when writers had decided that Superman was the "real" identity and Clark Kent a mere disposable mask.)
  • V from V for Vendetta. Who he is under the mask is unimportant, as the mask is a symbol of what he truly is.
  • In Silver and Bronze Age Superman comics, Lex Luthor initially only helped an alien race rebuild its civilization in order to gain their cooperation—but when they hailed him as a hero (even renaming their planet Lexor!), he realized he liked being considered a good guy. Lexor became his home away from home for years, until he himself accidentally destroyed the planet in a fight with Supes. This tragedy caused a major Villainous Breakdown.
  • Captain Atom was originally a government agent pretending to be a superhero so as to spy on the Justice League. Eventually he found himself becoming a superhero for real, leading to his Crowning Moment Of Awesome, seen here.
  • In the Fantastic Four story "This Man, This Monster," an unnamed scientist steals Ben Grimm's appearance, voice, and power in order to kill Reed Richards, whom he both envies and considers motivated solely by glory. However, in the course of working with him on a dangerous research project, the scientist becomes so convinced of Richards' selflessness that he sacrifices himself to save his life.
    • An Affectionate Parody of this story, "And Men Shall Call Him...Hero" from Doom Patrol, has a villain steal Cliff Steele's robotic body in order to kill his Doom Patrol teammates, only to feel unexpected compassion when a lost, frightened blind girl instinctively clings to him. As a result, he sacrifices himself in order to prevent the Omnicidal Maniac Celestius from absorbing her life energy.
  • Gentle Giant Vathek from the original WITCH comic begins as a villain, but is sent by Cedric to act as a The Mole among the rebels. Vathek, however, decides that Good Feels Good and ends up genuinely changing sides. (In the cartoon Vathek has a smaller role and acts as The Mole among the bad guys while being genuinely on the side of good all along.)
  • Happens both ways in Judge Dredd
    • On the one hand, Wally Squad Judges face a constant mental battle to avoid either becoming the criminals they're supposed to be undermining, or simply thinking too much like a normal human being. Many fail; at present, Dirty Frank is right on the precipice.
    • On the other end, Serial Killer PJ Maybe stole the identity of Byron Ambrose, a wealthy philanthropist, and got himself elected Mayor of Mega-City One. In order to keep up the charade, he had to do as many good deeds as were possible for the mayor - and during this time, he gradually came to enjoy being good so much that he risked his own life and reputation in attempting to assassinate Martin Sinfield for no other reason than that he felt it was for the good of the city. (Sure, he may randomly kill people for fun, but he was still the best mayor Mega-City One has ever had.)
  • A long running plot-point of Strangers in Paradise was the "Parker Girl" operation, women who would assume long-term, deep-cover identities and get involved with influential men in order to manipulate politics from behind the scenes. However, when the operation collapsed after the death of Darcy Parker many Parker Girls were trapped in their cover identities, unable to extricate themselves from the lives they had established. In Echo, the next series written by author Terry Morre, there is a Crossover with SiP as a character makes contact with some of the women still living their cover identities. Lieutenant Laura Higgs, who used be a Parker Girl named Stephanie who was infiltrating the US Military, asserts that she has a life now and refuses to give up the world she has built. "Stephanie's dead. I'm Laura Higgs now."
  • Zachary T. Paleozogt IS Zot
    • Except I wouldn't say this is the case, because "Zot" is just a nickname and there are no masks involved, literal or otherwise. Dekko, on the other hand, definitely counts. After getting contracted with a persistent disease, Dekko slowly replaces damaged body parts with mechanical ones, all the while becoming less and less human.
  • In Classic Star Wars, a set of Star Wars newspaper strips, Vader once hires an actor to pretend to be Obi-Wan in order to lure Luke into a trap. The thing was, the actor was moved by how Luke respected him, and started having thoughts like "What would the real Obi-Wan do?" He still led Luke into the trap, but then sprung it, dying himself. From Luke's utter lack of reaction before the panel at the top of the page, it's a little ambiguous whether Luke was really oblivious about what was going on.

Fan Works

"Don't be stupid, although I know you can't help that. Kiku's...not my type."
Also a lie, Heracles told himself. He definitely felt something for the other man, cherished his time with him and his quirks and just... all that made him who he was. When he kissed him, it was real. By now, everything he did with Kiku was real.

  • John-117 in Company 0051. As such, he certainly doesn't appreciate the having to be out of armor, and to make matters worse the armor in question is kept by a scientist who seems to have a bit of a fetish for it...
  • Explored in the Mass Effect/Terminator crossover Drift, where Cameron has spent a couple hundred years carefully developing an entire personality construct based on her "Allison" memories, effectively becoming an otherwise indistinguishable human. It turns out that Cameron has apparently been using the Allison persona for so long that elements of her have influenced other parts of her "brain," like her combat programs - which she finds quite troubling, because she is apparently unable to actually do physical maintenance on her processors.
  • In Deep Cover, a Naruto fanfic. Naruto gets sent on a mission to infiltrate the Sound village, with the idea that his behavior is so loud and obvious that nobody would suspect him hiding something. He betrays Konoha and has a romantic moment with Tayuya while watching it burn. Thinking back on how he made his decision, he realizes that at some point in the past he stopped caring about Konoha and decided that Sound was his home.
  • In Shadows of the Past, this is something Will wishes he could do.[context?]
  • Really, almost any Naruto fanfic that has the word 'mask' in the title.
  • White Rain has Itachi Uchiha and Lucia van Alstyne; the former's motivations were only revealed long after his death, while the latter only came to realize it after being interviewed by Ibiki.


  • The whole point of the Charlie Sheen film Beyond the Law, which in turn is based on several real stories about law enforcement agents who pretend to be outlaw bikers to observe the clubs engaging in illegal activities only to realize they feel more at home as outlaws than as cops.
  • Dana Carvey's character in Opportunity Knocks.
  • This is more or less the entire plot of James Cameron's Avatar. The main character, who is "piloting"/"possessing" an custom-made alien body for the purpose of infiltration, even remarks in the film at one point that the situation had become reversed - "out there was reality, and in here [in his human body] was the dream." At the end of the movie, he undergoes a ceremony that permanently puts him in the avatar body, and he leaves his old human body to die in the toxic atmosphere.
  • Again, it is the plot of Kagemusha by Akira Kurosawa. A lower-class criminal is taught to impersonate a dying warlord as a kagemusha (shadow warrior) in order to dissuade opposing lords from attacking the newly vulnerable clan. He becomes more and more convincing after the death of the warlord, but he is revealed as in impostor after he is rejected by the horse of the warrior. However he chooses a death on battle, in a desperate search for identity.
  • The main characters of Three Amigos are stars of many movies within a movie. A small Mexican village mistakes their movies for a truthful account of actual heroes, and hires them to save the town from bandits, while they mistake the offer for an offer to simply put on a show. Unfortunately, having lost their jobs, they have no place to go to after learning the truth, so they decide to save the village anyway, becoming the very movie characters they played.
  • In The Lion King 2: Simba's Pride, Kovu is sent to ingratiate himself into Simba's pride in order to kill him. Unfortunately for his mother, Kovu's growing love for Kiara allows him to break free of his mother's conditioning, realize the evil that he is collaborating in and decide he wants no part of it.
  • The main point of Wedding Crashers; this one using the "fall in love" variety with both protagonists. Things go south when they're discovered, but they manage to work out a happy ending.
  • Occurs for the worse in Mean Girls: Naive Newcomer Cady joins the popular girls' clique only because her friends want her to get inside information on Queen Bee Regina so that they can knock her several pegs down the social ladder. Cady succeeds in doing this, but her experience as one of the "Plastics" causes her to become as shallow and popularity-obsessed as them, and she takes over Regina's former position. Fortunately, when she realizes what she's become (and has a Fallen Princess experience), she snaps out of it and makes amends.
  • Experiment 626/Stitch in Liloand Stitch. He starts out masquerading as a dog for protection, but eventually Lilo's love causes him to do a Heel Face Turn.
  • Diego in Ice Age. He is supposed to get the baby and bring it to the Big Bad, but eventually becomes its protector.
  • A variant appears in Dave: an actor who bears an uncanny resemblance to the President of the United States is hired by advisors to stand-in at an official function whilst the real President is seducing his secretary. Unfortunately, the President suffers a stroke during the act and is rendered non-responsive, forcing the actor to remain in the role indefinitely; he ends up becoming a more noble and honest President than the actual one, and falls in love with the First Lady.
    • Pretty much based on Robert A. Heinlein's '60s novel "Double Star", minus the SF background.
  • The Music Man himself, Professor Harold Hill.
  • Alice in Anti Trust was originally hired to be The Mole, but ends up falling for the protagonist and refuses to betray him.
  • This is the main character problem affecting Robert Downey Jr.'s character in Tropic Thunder. Specifically, he's supposed to be an Affectionate Parody of Daniel Day-Lewis.
  • Inverted Trope in the first Darkman movie. When Darkman interacts with his girlfriend Julie after nearly having been burned to death, he makes good use of his artificial skin to pretend to be the same Payton Westlake he always was. However, at the end of the movie, when the Big Bad has been defeated and Julie finally sees Darkman's face as it truly is, she tries to reassure him by telling him that she can still love him despite his horrible injuries. Darkman replies that their former relationship could never go on because, while he was wearing the mask of the old Payton (among other masks), the man behind the mask had changed into an altogether different person.
  • Over the Hedge. RJ the raccoon.
  • This was the plot of the James Bond movie From Russia with Love; the Bond Girl was sent by SPECTRE (under the guise of SMERSH) to seduce him into a trap. She pretends to be a Russian cypher clerk who's fallen in love with Bond's picture, only to fall for him for real.
  • In While You Were Sleeping, Lucy saves the life of the man she has a crush on and, due to a mistake at the hospital is assumed by the staff—and the man's family—to be his fiancée, whom they haven't met. A variation, however, in that Lucy isn't a villain with malicious intent; she's initially mortified by the error and tries to clear it up right away, but finds the man's warm, welcoming and immediately accepting family, in contrast to her own painfully lonely life and lack of family, a bit too hard to give up. Then she falls in love with his brother—right before the man comes out of his coma and, due to what-he-thinks-is-amnesia, is convinced that she is his fiancée...
  • A variation occurs in the Woody Allen movie Zelig: the protagonist becomes the mask involuntarily, taking on the traits of whoever is around him, be they Nazis, pilots, or Greeks.
  • Undercover Brother has Brother become Anton Jackson to infiltrate The Man's company. He becomes the mask due to mayonnaise and the White She-Devil. When he returns to normal, the White She-Devil goes through a similar transformation and does a Heel Face Turn.
  • The Assignment (1997). The protagonist, a naval officer with an uncanny resemblance to Carlos the Jackal, begins to take on the nature of the violent, charismatic terrorist after being trained to copy his methodology (as part of a plot to frame Carlos as a CIA informant so he'll be murdered by the KGB). The final scene shows him going to burn a spider with his cigarette as Carlos did in the opening scene, but he stops at the last second.
  • Total Recall (1990) Does this quite literally (or does it?) - Our protagonist Doug Quaid is told that his true identity is actually Hauser, Cohaagen's evil sidekick: but Quaid has other ideas. As Cohaagen puts it: "I didn't want it to end this way, I wanted Hauser back, but no... you had to be Quaid!"
  • Pretty much the point of Donnie Brasco, where Johnny Depp's character, an undercover cop, develops a friendship with his primary mob contact and feels guilty about betraying him.
  • Something similar overtakes Matt Damon's character in The Departed, to the point where he actually kills the Big Bad. Also heavily discussed by Leo DiCaprio's character, where he worries that the horrible things he has to do while undercover are actually making him more of a horrible person, which culminates in him being unable to trust the police department at all, and going rogue to try to take out The Mole Sullivan.
    • Similarly, the main source of drama in Infernal Affairs, the Cantonese film The Departed is based on, was the psychological impact of the main characters' double lives as Andy Lau's character wishes to become his mask while Tony Leung Chiu-Wai's character fears he is becoming his.He eventually goes so far as to kill everybody who knew his real identity and could incriminate him, with the exception of his wife.
  • Burt Lancaster's Bill Starbuck, in The Rainmaker.
  • In Who Framed Roger Rabbit?, according to a comic book sequel, this is the origin of Judge Doom, who was originally a Toon specializing in villain parts and changing his appearance for every short, akin to a Toon Lon Chaney. After a grenade accident, the actor part of the "Actor playing a villain" slowly vanished and he never appeared out of costume/make-up, to the point that no one in Hollywood could remember what he looked like.
  • In the film version of V for Vendetta, Gordon Dietrich reveals to Evey that he not only keeps a ton of contraband art, religious items, and other memorabilia in a secret room, he also has a predilection for certain government-unfriendly sexual appetites. Or rather, he had these appetites before years of having to pretend he didn't . . .

Gordon: "You wear a mask for so long, you forget who you were beneath it."

    • Of course, this trope could be said to apply to V himself in both the film and the original graphic novel; after all, he no longer seems to have a personality outside of the one that goes with his mask.
      • This trope certainly applies to V. He says as much himself several times:

Evey: Who are you?
V: Who? Who is but the form following the function of what, and what I am is a man in a mask.
V: "There is a face beneath this mask, but it's not me. I'm no more that face than I am the muscles beneath it, or the bones beneath them."

  • In Batman Begins, Rachel is the one to point out Bruce is the mask, and that the man who was once Bruce Wayne has become the Batman, wearing Bruce Wayne's face as an alter ego.
    • Alfred warns Bruce of it earlier in the movie:

Alfred: You're getting lost inside this monster of yours.

  • Minor example: The father of the titular Lord of War was a Ukrainian who, along with his family, emigrated from the Soviet Union to America under the pretense of being Jewish. He would later on fully embrace the Jewish lifestyle, opening a store with the Star of David as part of the logo, faithfully attending synagogue services, and even obeying orthodox Jewish dietary laws, much to the annoyance of his Catholic wife.
  • Mr Orange in Reservoir Dogs is a cop who has infiltrated a gang of robbers, striking something akin to friendship with one of them in the process. During the heist and after it, the circumstances force him to lie through his teeth, kill in self-defense and allow others to take the fall for him, making him as guilty as the criminals themselves. Death Equals Redemption, but still...
    • As far as the spirit of the trope goes, it's only a partial example. While he does end up lying and killing to maintain the illusion, he does not abandon his duties as a police officer and turn to crime. And any guilt for his actions are purely on his own conscience, as lying to maintain his cover is exactly what he's supposed to do, and everybody he killed was out of either self-defense, or to protect a fellow police officer. His actions were still entirely motivated by his duty as a police officer, and would probably have been excused as such by his superiors. Where this trope does almost apply, however, is that it isn't "something akin to" a friendship. He comes to bond with Mr. White, especially after being shot, to such a degree that after the Mexican Standoff at the end, he admits to Mr. White that he's a cop.
  • In Plunkett and Macleane, Macleane infiltrates the rich upper classes so he can rob them blind with his fellow highwayman. However he begins growing too fond of acting like he's rich and squandering money on his gambling habits.
  • Subverted in Cypher when Morgan Sullivan's spy alter ego that he created for himself is ignored when Digicorp transplant him into his new identity by way of brainwashing. The next plot segment is driven by his annoyance that his new persona doesn't smoke or drink whisky.
    • Also inverted: The spy alter ego was his true personality re-asserting itself, Morgan Sullivan was the mask he was unbecoming.
  • This is the plot of Sister Act when Whoopi Goldberg's character becomes a nun.
    • Zig Zagged: Whoopi comes to like the nuns and their work to help people in need, but she also convinces them to serve the Lord with more joy and less woe, singing passionately.
  • Mr. Deeds Goes to Town and The Remake feature a reporter who stages a Rescue Romance with the main character to advance her journalist career and then falls in love with him.
  • Smokin Aces features an interesting inversion of this: after FBI Agent Freeman Heller goes undercover as Mafia Hitman Primo Sparazza, the higher-ups at the FBI became wrongfully convinced that he had become the mask, and tried to have him murdered. Heller survived the assassination, and to retaliate against the Bureau that betrayed him, really did become the mask, eventually becoming the head Mafia Don.
  • A classic movie example is Humphrey Bogart's character in The Left Hand of God. He plays a mercenary in China who uses the identity of a dead priest to escape his warlord employer but that means actually acting the part of a priest at a medical mission. Luckily he's a Catholic boy so he knows the drill. He also does his best to live up to the part with predictable results.
  • Point Break stars Keanu Reeves as an FBI agent who goes undercover as a surfer to get close to a suspected bank robber. The inevitable occurs.
  • The Brothers Bloom has one of the titular pair of conmen having to get close to an eccentric heiress as part of a con and, naturally, falling for her for real. (Then things start to go downhill...)
  • When Luke Skywalker surrenders to the Imperials in Return of the Jedi, he tells Darth Vader he has accepted that he was once Anakin Skywalker, his father. Vader replies, "That name no longer has any meaning for me." Luke insists there is still good in him.
  • One of the themes in Black Swan is the protagonist struggling to delve into her darkside in order to perfect her role as Odile of Swan Lake. This unfamiliar side of herself begins to devour her.
  • Zig-zagging around this trope is one of the main selling points of Salt: Is she primarily a CIA operative trying to clear her name or a Soviet superspy? The theatrical version plays this straight; She did fall in love and went native. The Directors Cut goes the opposite way but manages to sneak in a twist: She's loyal to current Russia, not Orlov.
  • This is the central plot of Rango.
  • Just Go with It is a recent Romantic Comedy where two people that have to pretend to be a couple actually fall in love with each other.
  • Jill in The Whole Nine Yards. She was hired by Oz's wife to kill him, so she started working as his assistant, to get closer ti him. She ended up liking Oz so much she couldn't go through with it, and just kept on working for him.
  • Despicable Me has Gru pretending to be the three orphans' adoptive parent. However, he rescues the three kids from Vector and keeps that role.
  • Megamind has this, but it's a subversion. He begins to like Roxanne while dating her as Bernard so much that he doesn't want to be a villain anymore. However, after Roxanne dumps him after finding out his identity, it's back to being a villain for him.
    • But when Roxanne tells him she needs him, while Titan has her tied up on top of a skyscraper, he flips to "hero" mode again and stays that way.
  • Ronald Colman won his only Academy Award for doing this in A Double Life. He plays a Shakespearean stage star who is something of a method actor, immersing in and "becoming" each role. Already having (actual, but unfounded) concerns about his wife's fidelity, he then gets cast as Othello...
  • Played straight in Captain America: The First Avenger. Steve started out as a USO propaganda figurehead, playing the heroic Captain America in stage productions and advertisments. Then, he became the real thing.
    • Inverted with Red Skull. The characteristic red head that Red Skull is his true face and the human face was only a mask resembling his original face. It's stated in an interview with Hugo Weaving and implied in the movie that the red head was a result of the incomplete supersoldier serum due to his dark inner nature.
  • Kayla Silverfox in X Men Origins Wolverine is blackmailed by Stryker into posing as Wolverine's lover. However, near the end, the mask has become real.
  • Done to the letter in The Baker, a British comedy about an assassin with second thoughts about his profession who escapes to a tiny Welsh town and poses as the local baker to avoid attention. Turns out, he likes baking a lot more than he does killing, and a local girl captures his attention. Sure enough, he ends up as the town's baker, and gets the girl.
  • The danger of the unicorn's human guise in The Last Unicorn. Amalthea, the eponymous unicorn, slowly forgets who she was, as she becomes more and more human. It takes the three others protagonists (including the human she felled in love with) to put her back on her quest.
  • In The Wild Hunt, Murtagh and his fellow Celts start playing their LARP characters for real, with bloody consequences.
  • Kichi's mother begins to worry that this has literally happened to her after she dons a demonic mask in an attempt to scare her daughter straight in Onibaba.
  • In Plan B, Bruno attempts to seduce his ex Laura's boyfriend Pablo as part of a convoluted plan to win Laura back, only to end up developing genuine romantic feelings for Pablo.


  • In the Boundary's Fall series, Katya is one of many agents sent to infiltrate Alrendria by Tylor Durange to act as spies and, if need be, assassins. She falls in love with Dahr but continues to pass along information until a critical moment, when Jeran, who has figured out the secret, has himself handed over to Tylor as a diversion so that Prince Martyn can escape. Manages to combine both the My God, What Have I Done? and the Heel Face Turn options.
  • There's an intereseting variation of this trope in the Warrior Cats series. It turns out that Scourge was a product of this, but in the reverse of the norm: See, when he was little, he was tricked into running away from his home and happened to end up in the city. To survive, he managed to fool the other rouges residing there into believing that he was a cold-blooded killer so they would fear him and bring him free food. However, by the time he actually kills someone, he slowly starts to become the unfeeling, cold-blooded monster he was portrayed as in his debut.
  • In Henri Duvernois short story "Clothes make the man", a trio of thieves has one member wear a police uniform as part of their plan. At first he doesn't like it, but after being treated like a cop he 'arrests' his fellow thieves.
  • In Good Omens it's repeatedly pointed out by other demons that this seems to be what happened to Crowley; he's spent so much time making sure he fit seamlessly into the role of the human he's supposed to be that he became that person over time, and eventually comes to really love humanity. Aziraphale does this as well, integrating into humanity well enough that he becomes enough of a bastard for Crowley to spend several millennia with.
    • Likewise, at one point, Adam the young Anti-Christ is sent a massive Hellhound which takes the form of small yapping dog as a disguise. It grows to enjoy its new form and carefree life of catching sticks more than it ever enjoyed chewing up the souls of the damned and such. The presence of female dogs probably didn't hurt much.
      • Yes and no with the hellhound. While the dog definately DID prefer Earth to hell in the end, the reason he took the smaller form wasn't as a disguise but because whatever the Anti-Christ named him, would define him and Adam chose the name 'Dog'. So he became the perfect embodiment of a dog, changing him from the very start.
  • The plot of The Assassins of Tamurin centers around the Femme Fatale protagonist realizing that, contrary to what the Cult she's grown up in has taught her, she's been on the wrong side. Not only does she really fall in love with the king she's been spying on, she believes his plans, not The Chessmaster's, are best for the kingdom.
  • In Aaron Allston's Wraith Squadron books of the Star Wars Expanded Universe, Lara Notsil fits this trope to a "T". Not only does she, over time, wish to become a Rebel in truth, but the person she eventually falls in love with, Myn Donos, is the sole survivor of a slaughtered X-Wing squadron, one which her information had helped to destroy! She gets to declare her love before her identity as The Mole is exposed—and even with everyone believing her to be an Imperial, she still goes on to do the right thing and bring down Zsinj and, by strong implication, still gets her man in the end.
    • And a later book by Allston mentions Donoslane Excursions, whose name is based on Donos' and one of Notsil's fake identities (rather, the one she decided to live by after her identity crisis), Kirney Slane.
    • Another example, from some older comics: Darth Vader hires an actor to act as Obi-Wan to lure Luke into a trap, but the actor starts to see why Luke admires the figure he acted as so much, culminating in a Heroic Sacrifice.
    • The Hand of Thrawn Duology has the Devist family, a number of clones of Soontir Fel who kept together and secretive to avoid the Fantastic Racism that comes with being a clone. They were set up as a cell of sleeper agents, supposed to answer the call when the Empire needed them, and in the mean time they became farmers. But like Soontir before them, they loved the soil, and loved it more than the Empire. When they scramble in their TIE interceptors and save Han and Leia, they don't report them, and are eventually talked into helping the New Republic with the Camaasi Document crisis.
      • Fel himself states that they and the other cells were designed to do this - to develop stronger loyalty to each other and their world than to the Empire that quite literally created them. This way, when a threat came past the galaxy's edge, they would be able to fight it without too much worry about ideological ties. Pity the villains dug most of the cells up to act as cannon fodder well before that...
    • Luke Skywalker and the Shadows of Mindor has Luke half-awake during an eternity after the heat death of the universe, after all the stars have burned out. He escapes the projection of this eternity before he can despair enough to let his body be stolen, but for quite some time later he's cynical, depressed, even nihilistic, believing that all of his friends are using him and nothing will matter in the end. He's Luke Skywalker, so he very consciously decides to act exactly like he would have before going through that, hoping that eventually it will stop being an act and he can "fall back into the dream of the light". Fortunately he doesn't have to wait that long before regaining his faith during a Mind Screwy metaphor-heavy sequence.
      • Luke seems particularly prone to this trope. It's the only thing anyone remembers about Dark Empire. That and the Emperor's clones.
    • Lowbacca in Diversity Alliance. He isn't racist, but he can see where the titular group gets their ideas from. Even though they're basically the Flanderized version of the Black Panthers.
  • Robert A. Heinlein's Double Star is about an actor who is hired to impersonate a kidnapped politician so that an election won't be disrupted. As time goes on the job gets stretched longer and longer and then the politician dies, with the masquerade still in place. He has to keep up the impersonation for over 25 years, and pretty much becomes his role. (He was an anti-Martian before the job, and is hired to impersonate one of the biggest pro-Martian activists. By the end of the 25 years, he has completed all the causes of the politician, and more.)
    • Similarly, in his earlier novel Sixth Column there is a hobo who was originally an academic studying hobos who fell in love with the lifestyle.
  • In C. J. Cherryh's Invader series, a wandering starship's crew are marooned on a planet of nine-foot-tall humanoid aliens, called 'atevi'. Unable to understand human emotions or the idea of love and friendship, they went to war against the perceived threat to their way of life. Human annihilation was only prevented by scholars on both sides equating the "English" (or should that be Basic?) word for treaty, with man'chi, the ateva word for association, a hard-wired homing instinct under fire. Since then, humans live on the island of Mospheira and the atevi of the Western association remain on the continent. No one is allowed to make contact between the two except the interpreter, or 'paidhi'. Bren Cameron becomes so attuned to atevi mindsets and language that he eventually becomes aligned with their point of view and begins to lose human feeling. He cannot show any form of emotion, because that would be deemed extremely threatening by atevi, whose legal recourse in disputes is assassination via an Assassins' Guild. He gradually takes on their mannerisms and can no longer remove the bland, impassive expression on his face - literally becoming the "mask" that he has to wear in public on the mainland.
  • In the little known sequel to The Prisoner of Zenda, Rupert of Hentzau, the protagonist who had impersonated the King of Ruritania in the first book finds himself forced to masquerade on a permanent basis in the sequel although he is assassinated shortly after this happens.
  • Occurs in reverse in CS Lewis The Great Divorce. A man who keeps trying to impress his love interest slowly becomes "The Tragedian", a false personality given to hackneyed dramatic gestures, and his real, honest (if average) personality gradually shrinks away to nothing. Ironically, she loved him as he was.
  • Moist Von Lipwig in Going Postal.
    • As we see later in Making Money, though on the surface he seemed to embrace his new job, his criminal's instincts have never left, and he becomes more and more dissatisfied with it as time goes on. A rare instance of seeing what happens after Happily Ever After.
      • Rare outside of Discworld. Pratchett is relatively fond of this in some respects.
    • His criminal instincts remain, but he acquires a strong drive to use them for good. (He was a sort of Anti-Villain before, but has definitely graduated to Loveable Rogue over the course of his new career).
    • Also, Walter Plinge in Maskerade eventually Became The Mask permanently, with a little help from Granny Weatherwax.
    • In Monstrous Regiment Seargent Jackrum. Not only has she been in disguise long enough to make a detailed account of every other female hiding in the ranks of the army, she also has evaded her service papers discharging her from the army for years. As the war ends, she admits to Polly that she doesn't want to return home to just be an old biddy. Polly suggests that she keep the mask and return home as a respected retired sergeant instead.
      • From the same book, The command staff who became just as eager to punish women, as Jackrum eventually warns Polly to avoid the same pitfall.
      • Earlier, Polly herself, when she has infiltrate the fortress recursively Disguised in Drag, gets caught because she still walks like a boy.
    • The Auditor from Thief of Time who becomes Lady Myria. In fact, a lot of the Auditors who take on human form start to act gradually more and more human. Lady Myria is just the only one to make a genuine Heel Face Turn.
  • Michael Moorcock's Behold the Man uses this trope quite effectively.
  • Max Beerbohm's The Happy Hypocrite makes this Older Than Radio. It features a literal mask to hide the signs of dissipation in the villain's face; when the villainess realizes the truth and pulls off the mask, the face beneath has literally been molded into the mask's form.
  • In the series Instrumentalities of the Night, by Glen Cook, protagonist Else Tage is sent on a mission to spy on the west for the kingdom of Dreangor (i.e., Muslim Egypt). Pushed along by the fact that the Evil Chancellor responsible for sending him on the mission is trying to have him killed, he starts questioning his loyalty. This process is clearly indicated by the fact that after spending the first book referring to him as Else, the narration switches to calling him by the pseudonym he's using.
  • Kurt Vonnegut's novel Mother Night is about an American who moved to Germany and was later hired to spy on the Nazis. While never consciously converting to Nazism the main character is eventually held for being a Nazi war criminal. The character himself is actually unsure of which side he belongs to. The introduction of the novel lampshades the theme when it says "We are what we pretend to be."
    • This might be something of a Secret Identity Identity.
    • The story is An Aesop about the fact that what you do is more important than what you believe. You are good or evil based on your acts, not whether or not you think you are good or evil. As for the protagonist, he was asked to become a Nazi by an American agent and the information he provided the Allies throughout the war was of great help. The problem he has is illustrated when near the end of the war a Nazi friend tells him he knew the protagonist was a spy but never reported him because whatever damage he did as a spy would be more than offset by the help he was giving the Nazis in his cover role. Obviously, that would bother any anti-Nazi person, which he was.
    • Cat's Cradle, by the same author, has a religion created by two men to keep a country happy. They decide to have the religion outlawed, with one playing the role of President, the other The Messiah. Eventually, of course, the President gets too deep into his role and starts executing heretics.
  • In the Vorkosigan Saga, Miles Naismith Vorkosigan finds himself becoming Admiral Naismith (his fictional identity) more and more, and Lord Vorkosigan, his actual identity, less and less. This is helped by the fact that the reason he created and maintained his fictional identity was to have an outlet for the drives and urges his true identity is not permitted to indulge in. However, Memory happens and Miles finds his alter ego destroyed—and he realizes that after everything else has been stripped away, he's still a Dendarii hillman in his bones. In other words, his Naismith persona had to always succeed, but his Vorkosigan persona simply didn't know how to lose. Miles successfully adjusts by finally allowing his true identity to fulfill the impulses his alter ego had been satisfying, though his mother claims she thought he'd flee Barrayar and "choose the little admiral".
    • And his clone, Mark, was brainwashed and trained from birth to impersonate Miles, and after breaking free of his captors he struggles for years to find his own personality and avoid Becoming the Mask.
  • Agatha Christie pulled this one with Dr Rathbone from They Came to Baghdad: a con man who established a philanthropic society to make money, but ended up believing in what he preached.
  • G. K. Chesterton's book The Man Who Was Thursday has a character who was an actor that portrayed an anarchist philosopher as a joke, and did such a good job of it that he convinced everyone watching that he really was the philosopher and even bested the philosopher himself in a debate, resulting in the real philosopher getting tossed out into the street. He is then forced to continue playing his role, even when he was elected to the Council of Days. By the time he meets the protagonist, he's been playing the part of an old man for so long that he can't stop.
  • In Ender's Game, Valentine starts to worry about adopting "Demosthenes"'s more radical, hard-line opinions after writing too many columns under that name. (Whether Peter is similarly worried about becoming "Locke" is unknown.) She uses that as the basis of another article - that people who give in to the Warsaw Pact will end up giving up everything (note that there's some historical evidence for this idea - just ask Neville Chamberlain).
    • Whether Peter is worried about the possibility, this occurs to him throughout the Shadow series. Contrasting the sadistic boy in Ender's Game to the non-aggressive Hegemon in Shadow of a Giant displays how Locke's persona changes Peter Wiggin.
  • In Star Wars, Boba Fett occasionally mentions that this is how he became the bounty hunter he is, by working out how a hunter "should" act and sticking with it until it became second nature. Understandably, it wasn't very good for his social skills.
  • In the classic SF story Private Eye by C.L. Moore and Henry Kuttner, the main character radically changes his identity in order to give himself an alibi for a murder is planning. Since the police have chronoscopes in future, he needs to play the role to the hilt. At the end he realizes he liked his new identity better.
  • The title character of Montmorency starts out as a thief in the Victorian era, who concocts an upper-class identity so he can fully savor the profits of his crimes. Eventually, he finds life as a respectable gentleman so satisfying that he goes legit, retiring the original thief-persona he's grown ashamed of, and anonymously making amends for his crimes.
  • Fidelias in the Codex Alera takes a position in the First Aleran legion as the Aquitaines' spy. However, he finds that he rather enjoys being Valiar Marcus, and eventually betrays the Aquitaines to support Tavi, who he has decided would make a better ruler. (The fact that he's the rightful heir is entirely incidental) Even the sections from his perspective tend to refer to him as Valiar Marcus rather than his real name, Foreshadowing how absorbed in the role he gets.
  • Jack London's short story "South of the Slot" features a sociology professor who adopts a working-class persona to write about the culture from a scholarly standpoint, but finds himself spending more and more time as the rowdy labor-hero, until he eventually forsakes his career and impending marriage to become the other persona full-time.
    • This,sort of, the plot of both his "The Call of the Wild" and "Whitefang." In the former a pampered pet dog is dognapped and becomes first a sled dog and then alpha wolf of a pack of Alaskan wolves; in the latter a wild wolf becomes a beloved pet. These would not really fit except that both stories are essentially told from the first person perspective.
  • This is arguably the entire point of The Name of the Wind, though it's not clear until the end of the first book. Bast, the hero's student is worried that Kvothe is no longer a hero pretending to be an innkeeper, as he "doesn't take off the innkeeper when people leave anymore." To combat this, he deliberately "gets drunk" and leaks that Kvothe is the innkeeper, in the hopes that someone to remind him of his old life will come by. Chronicler is described as "perfect."
  • If at Faust You Don't Succeed (Millennial Contest, #2) By Roger Zelazny and Robert Sheckley
    • The harried archdemon Mephistopheles mistakenly signs up a medieval cutpurse named Mack the Club for the do-over of the Millenial Contest, thinking him the learned Dr. Faust- And Mack doesn't argue his identity, as he doesn't want to get in trouble with Hell itself for trying to rob the great magician Faust. Mack eventually becomes the historical Faust by being better at being Faust than Faust himself- much to the original's wrath.
  • In the Anita Blake book Obsidian Butterfly, Anita is extremely concerned that her friend Edward, the sociopathic assassin, has proposed to a woman with two children under the guise of Ted Forrester, his respectable Federal Marshal identity. She quite thoroughly berates him about exactly how he managed to let his personal life get quite so out of control but relents when he manages to show her that he really does love his soon to be family. Of course, this involved Edward as Papa Wolf, Anita as Mama Werebear and a large body count when the bad guys decide it is a good idea to kidnap Edward's soon to be step children even when they know who he is.

  • O. Henry's "A Retrieved Reformation". Master safecracker Jimmy Valentine poses as an ordinary salesman in a town, and becomes the mask to the extent that he gives up his old life and plans to marry the banker's daughter. He even arranges to get rid of his trunk of safecracking tools. And then, on the day he hauls the trunk into town to get rid of it, the one cop who might recognize him shows up hunting him. And a child gets trapped in the bank's vault in such a way that only a master safecracker could possibly get her out before she suffocates.
  • In the Belisarius Series, Damodara starts as a Reasonable Authority Figure, but after being in command of the honourable and noble Raput army he can't claim everything he does is based on mere practicality about not offending them. Even the Ye-Tai assigned to the army, despite the general opinion of the Ye-Tai on both sides of the conflict as being brutal barbarians, start behaving better, with the resulting increase in respect granted to them.
  • In "The Mark of the Horse Lord" by Rosemary Sutcliff, Phaedrus the gladiator impersonates Midir the king even dying to save his people.
  • Fulbert from the post-Apocalypse novel Malevil. He claims to be a priest but almost certainly wasn't one from before World War III. However, after he is seen in action it's revealed that even if he wasn't one before, he's certainly become an effective one since adopting the role. Unfortunately for Malevil, there is no change of heart with Fulbert and he is a Sinister Minister.
  • A central theme in The Kingdoms of Evil
  • In Eric Ambler's Journey Into Fear, Mathis, a fellow passenger of the protagonist on the eponymous journey, is a French socialist. Towards the end of the book, he reveals that by origin he was from the impoverished fag-end of the French aristocracy and a royalist who was henpecked by his snobbish petite bourgeois wife. After accidentally mortifying her in front of her friends by repeating the opinions expressed at a socialist meeting he attended out of curiosity, he started adopting deliberate public espousal of socialist views whenever she was unreasonably vicious to him. In the course of reading the books and pamphlets he buys to make his arguments more damaging (coupled with his experiences as a combatant in WW 1), he comes to believe in the truth of his pretended views and becomes a socialist by conviction (to the extent of being dismissed from his post of the manager of a factory when he supports its striking workers).
  • In A Song of Ice and Fire, Sansa Stark undergoes this when masquerading as Littlefinger's bastard daughter. She starts thinking of herself as Alayne Stone, her fake name, and refers to Littlefinger as her father, even while he's making sexual advances on her.

He eventually becomes an actual Unstoppable Mailman and creates a network of post offices.
  • One Sesame Street short story had Big Bird pretend to be sick, only to fall sick for real the next day. He does get better by the end of the story, though.
  • Ignazio Silone's Bread and Wine concerns a Communist fugitive in Fascist Italy who disguises himself as a priest and grows into the role, discovering a version of socialism more consistent with religious faith. In a possible Real Life twist, although Silone's public identity was as a Marxist turned anti-Communist leftist, historians in the 1990s alleged he was an informer for Mussolini's fascist government.
  • Eleanor Farjeon's "The Kind Farmer" was a Jerkass who did some routine courtesy for a poverty-stricken widow who didn't know him. She told the whole town about his kindness and kept hanging around helping him out until he married her. For her sake, he kept up the "kind" facade. When she died in childbirth, he had to go right on being "kind" because of his daughter.
  • Happens to Vlad Tepes in Count and Countess, who initially just wanted revenge against his father and the Ottoman Empire for the deaths of his brothers. At first his cruel practices (especially the impalement) are meant to psyche out the enemy army, with whom he spent some time as a child, but the more cruelties he undertakes, the more commonplace he finds them.
  • In The Hunger Games, this occurs when Katniss pretends to be in love with Peeta just to keep them both alive in the arena. By the end of the second book, at the least. At the end of the first she's prepared to kill him to save herself. Contrast the end of the second, where she's totally prepared to die so he can continue living. At the end of Mockingjay, she chooses Peeta over Gale.

Live-Action TV

  • One episode of Castle deals with this. A con artist dates a rich girl in order to get her money while his partner finds her way in as a servant. The guy falls in love with the rich girl, however, and tries to break off the con. His partner kills him and tries to get away with it, but Castle and Beckett trick her.
  • In season 2 of Heroes, Mohinder is originally working with HRG to infiltrate the Company, but eventually switches sides and betrays him, joining the Company for good.
    • It's a popular (if not obligatory) concept in Sylar/Mohinder Fan Fiction that the two became infatuated with each other while Sylar pretended to be Zane during their roadtrip to Montana. Angst ensues.
    • Sylar receives an involuntary Nathan mask at the end of season 3.
  • Sharon/Athena in the 2000s Battlestar Galactica is ordered by the Cylons to make Helo fall in love with her and impregnate her. She ends up falling in love with him as well, and defects to the humans. Indeed, she becomes more anti-cylon in her attitudes than many humans.
    • Later, Boomer, another copy of Number 8 seduces/manipulates Tyrol to get him to help her but she hesitates to go through with it and soon regrets her actions.
    • Another minor example is Kat whose real name was Sasha. In her previous life, she used to be a drug runner and a smuggler which is where her piloting experience came from. When the Colonies were nuked, she took the name and identity of another woman that she knew was dead and worked herself a fake background and all. By the time her previous life caught up with her in Season 3, she was fully immersed in the identity she built herself.
  • The 1980s detective series Remington Steele. The Mole (Pierce Brosnan) initially impersonates the fictitious Steele as a place to hide, but eventually settles into the role, even marrying the woman who created the persona in the first place.
  • Sawyer from Lost falls in love with the woman he is conning, and confesses to her that she was being taken advantage of. He then proceeds to carry through with the con and steal her money anyway, albeit with some apparent remorse.
    • In season three, Juliet was meant to infiltrate the survivors in order to determine whether any of the survivors were pregnant, but by the end of the season she's firmly on the side of the survivors.
  • Will Traveler in Traveler becomes fond of the two roommates he's setting up, and ends up sparing their lives (at great cost to him later), against the plans of his employers.
  • Cole Turner (Belthazor) in Charmed was sent to kill the Charmed Ones before love redeemed him and he abandoned his demonic power. Subverted in that he eventually found himself in dire need of power to protect his loved ones and snapped back to his demonic conditioning and tried to marry Phoebe in part of a long plot to set her up as queen of Hell and effectively spawn The Antichrist.
  • In Buffy the Vampire Slayer, Faith began her Heel Face Turn like this. She switched bodies with Buffy. But after living only one day as Buffy, she effectively became Buffy. Or rather, her own semi-warped sense of what Buffy was like. She even attacked Buffy-in-Faith's-Body, screaming that she was evil.
    • The latter was most likely a reflection of her own pre-existing self-hatred rather than a result of becoming the mask.
    • Also, she deliberately practiced what she believed to be Buffy's catchphrase, "Because it's wrong," in order to deceive Buffy's friends (and Spike), but ends up using that exact phrase when facing a group of vampires in a church. That one time, she actually means it too.
      • Another Buffy example: Jenny Calendar is revealed to be Janna, a member of the clan of gypsies who cursed Angel with his soul, after he experiences 'true happiness' with Buffy and reverts to the evil Angelus. It's heavily implied that her love for Giles ("I didn't know I would fall in love with you") led to her Becoming The Mask, and after she is killed by Angelus, she's buried under her assumed name of Jenny Calendar.
  • An unusual example of this takes place in The Sarah Connor Chronicles episode "Allison from Palmdale." Cameron, suffering a glitch due to damage to her chip, briefly adopts the personality of Allison Young, the resistance fighter whom she was modeled after and whose personality she copied, before going off to assassinate John Connor.
  • A somewhat perverse version occurs in Dexter, where Dexter begins as a completely amoral psychopath who's also phenomenal at pretending to be normal—but after a while, pretending to be normal starts to get to him... Unusually for the trope he seems to find Becoming the Mask an improvement on being a type B Stepford Smiler and welcomes it. He even advises a budding Serial Killer to do this in an attempt to stop feeling empty.
  • In Kamen Rider Kabuto, the Scorpioworm assumed the identity of Kamishiro Tsurugi, but prior to the beginning of the series somehow came to believe himself to be Tsurugi to the point at which even he is shocked when the mask slips.
  • Played out interestingly in Prison Break: T-Bag (who is someone who definitely can't redeem himself, despite being awesome) has this with his fake identity of Cole Pfeiffer, a charming top-salesman. He actually hopes to leave his past as a convict behind, because he really seems to love his role. In the end, it doesn't work.

T-Bag: "You realize what I'm giving up here? I was guaranteed 50 grand!"
Gretchen: "You're crying over 50 grand, are you serious?!"
T-Bag: "I have a job! I make money, I get mail, people call me sir."
Gretchen: "12-hour days and eating left-over lo-mein. Something tells me Theodore Bagwell wouldn't last long in this situation."
T-Bag: "Yeah, maybe. But Cole Pfeiffer would."

    • Subverted in a later episode: T-Bag takes a proactive step towards being a Cole Pfeiffer-kind of guy by not killing a man he's holding hostage, who could be either an innocent Bible salesman or an evil Company agent. Turns out he was a Company agent after all. Violence ensues.
  • In the original UK version of Life On Mars, Frank Morgan suggests this as the cause of Sam Tyler's condition. The series also ends on this trope with Sam willingly immersing himself into 1973, though exactly how he does this is never fully revealed.
  • In season four of NCIS, Tony begins a year-long relationship with Jeanne Benoit as part of an undercover operation against her father, arms dealer La Grenouille. He genuinely falls in love with her in the process, which doesn't stop him from answering her inevitable "Was any of it real?" with a simple "No."
    • The same idea was used in an episode about North Korean sleeper agents, in which one of their number turned against the rest for the sake of her American husband and baby daughter.
    • Ziva also turns out to be someone who was originally sent as a spy, but grows more loyal to NCIS than her father and Mossad; so much so that she became a naturalized US Citizen so she could stay on as an official NCIS agent.
  • A bittersweet version occurred on a Mother's Day episode of Saturday Night Live: The late Phil Hartman is with his mother, and he cannot get out of character. His mother calls him on it, and he realizes that he's spent so much time as other people he doesn't really know who he is. Mom knows who he is, though, so it'll be okay. *sniff*
    • That also happened in Hartman's monologue when he first came back to host in season 21, where Hartman does his monologue in different voices and runs crying into his dressing room, realizing that he's been playing so many characters and doing so many celebrity impersonations that he doesn't know who he is anymore.
    • Similarly, when he appeared on The Muppet Show, Peter Sellers informed Kermit that he had had his real self surgically removed. (See his entry under Real Life, below.)
  • In My Name Is Earl, Earl at first only tried to make up for all his past bad deeds because he believed "karma" would punish him otherwise. But eventually, he starts to really care about people.
    • Same with Billie, who at first hides among the Camdenites (radical Amish) while plotting revenge against Earl. However, the simple lifestyle eventually wins her over, and she joins their community, giving Earl all her money.
  • The Twilight Zone episode "The Masks" does this, quite naturally, with a Karmic Twist Ending: a dying man makes his overly-eager-for-the-inheritance relatives wear masks as a condition of inheriting. The masks are nasty caricatures of their inner selves, and they end up quite literally Becoming the Mask.
  • Oz. Undercover cop Desmond Mobay, posing as a Jamaican drug dealer, gets hooked on drugs and murders a corrupt cop turned inmate who threatens to blow his cover. Another prisoner, convicted copkiller Augustus Hill, realises who Mobay is and calls him out over his hypocrisy. Mobay beats Hill unconscious, but then confesses to the murder, realising he's become one of the criminals he's supposed to be fighting.
  • The X Files: An alien invader, infiltrated as a human baseball player, eventually decided he was a better person that way. When another alien came to execute him and ordered him to show his real face, he answered that it was his real face.. Even his poisonous blood has somehow changed human when he is killed.
    • Even Scully sort of qualifies as this. The original reason for her assignment to the X Files was to spy on Mulder and discredit his work. Though in her case, the powers that be chose the wrong person for the job, since it didn't take her long to become close friends with Mulder, join him on his crusade and even eventually help expose the man who gave her the assignment in the first place, Section Chief Blevins.
  • When Chuck Bartowski first became the Intersect, it was an accident, and he was forced to work as a spy and foil terrorists and other bad guys against his will; a fact he complains about constantly. The show focuses on how Chuck slowly but surely begins embracing his saving the world role without coercion. Agent Walker in particular points out that although he denies, he really is a hero. At the end of Season 2, Chuck literally becomes the Intersect, again. And this time completely by choice.
    • Sarah also finds herself actually falling in love with the guy she was supposed to be fake-dating for the sake of their covers.
      • A flashback scene even shows that Sarah initially considered Chuck a dateless chump and that seducing him would be a "piece of cake."
    • An interesting case with a nerdy British young man who became a test subject of an experiment similar to the Intersect project, except this one involves completely replacing the subject's personality with a new one in order to create a perfect mole. Unfortunately, it ends up working a little too well. The man becomes one of the most powerful criminals in the world, being none other than Alexei Volkoff, a Magnificent Bastard.
  • Although he never forsook his real loyalties, undercover fed Vincent Terranova often formed strong personal connections with the criminals he investigated on Wiseguy. His friendship with Sonny Steelgrave was so genuine, Vinny openly admitted he would have allowed the mob boss to escape, had Sonny not personally beaten a man to death in front of a hidden camera.
  • Doctor Who—Being stranded on Earth, Blon Fel-Fotch Passameer-Day Slitheen got to know and enjoyed the everyday human rituals she conducted as Margaret Blaine. To the point where the Doctor has to point out that she is pleading for mercy from a dead woman's lips.
    • Blon also shows signs of getting too into the part earlier when her escape plan causing destruction on a global scale is discovered by The Doctor & Co. When queried why no human authorities had notice a nuclear power plant in the middle of the city designed to go apocalyptic?

Blon: London doesn't care -- the South Wales coast could fall into the sea and they wouldn't notice? Oh? I sound like a Welshman. God help me, I've gone native!

  • In one episode of Monk, he joins a cult to investigate claims that its leader murdered an ex-member, but he actually starts to get sucked in to its teachings when he finds that they help him overcome his OCD. It's also present to a lesser extent in the episodes where he goes undercover as an office worker and a butler, only to find that those jobs suit someone with his obsessions extremely well.
    • On the other hand, pretending to be a hitman who happens to look identical doesn't work out so well.
  • Angel: Lilah admits to Angel in season 3 that she became her "game face" long ago.
  • Happens to Quinn in Glee - she first joins the club to spy on it for Sue, hoping Finn would lose interest in Rachel if the club disbanded. She ends up enjoying the club enough that she does a complete Heel Face Turn, even saving the club when Sue seems successful in disbanding it. (It's debatable, though, how much Quinn would have BecomeTheMask if her pregnancy hadn't turned her into a Fallen Princess, though.)
    • Also Santana who was also a spy at first but has admitted that Glee club is the best part of her day.
    • Quinn's case is a lot more complicated than a simple straight playing of the trope. For one, it could be argued (and the show gives glimpses of this) that her previous identity as Alpha Bitch and Seemingly-Wholesome Fifties Girl was more of an act than her role in the Glee Club, but she didn't realize it until she got pregnant and Glee was the only thing remaining from her former life. Certain scenes suggest that Quinn was under a lot of pressure from both Sue and her parents to live up to certain expectations, whereas Glee gives her more of a chance to truly express herself. So it may be more of a Secret Identity Identity - maybe we don't always know which part is "real" and which is the mask.
    • Arguably happens with Jesse, as well.
  • Leverage has a humorous non-evil version. Eliot has to play the part of a baseball player as part of a con, but as he tells Hardison before the con, he doesn't like baseball. However, as the con goes on, it turns out that not only is Eliot really good at baseball, but he starts to enjoy it too. He even gets a sandwich named after him. It leads to the following exchange:

Nate: All right, good news, bad news.
Tara: Good news?
Nate: The mayor's hooked. We're in the pinch.
Tara: Bad news?
Nate: I think we lost Eliot until the playoffs.

    • This was also the in-show reason for Sophie's absence when Gina Bellman went on maternity leave. Sophie had worked under so many different personas as a grifter that she wasn't sure who she was anymore, and she needed time to really find herself. Sophie isn't even her real name, it is merely the name she had adopted as her primary identity.
  • Star Trek: Deep Space Nine has an episode where Miles O'Brien infiltrates an intergalactic crime syndicate and in the process forms a genuine friendship with Liam Bilby, a local crime boss. Throughout the episode Miles becomes increasingly conflicted, and ultimately attacks his Star Fleet liaison and tries to warn Bilby that he has been compromised.
  • In Season 2 of Alias, Allison Georgia Doren, disguised as a replica of Francie Calfo, actually falls in love with Will Tippin and is visibly upset when she is forced to kill him.
    • In a Season 2 episode the wife of an American mathematician (guest star Christian Slater) turns out to be a Russian agent who fell in love with him for real. It also turns out her husband was an NSA agent and knew his wife was all along.
  • In one episode of Xena: Warrior Princess some random guy shows up wanting to kill Xena to build his reputation as a warrior because he wants to become a great warlord. He claims to have killed other fearsome warriors as well. While he does have the skill to back up his claims, it turns out he has never killed anyone in his life—Xena realized this when she remembers that she actually killed one of the warriors he mentioned. Xena warns him that people eventually truly become what they pretend to be after a while. At the end of the episode, the guy decides to pretend to be something he can live with and try his hand at being a hero.
  • Fringe: One shapeshifter at least (maybe two) got very attached to their family.
    • Another example occurs with Fauxlivia, who impersonates the real Olivia in order to gain Peter's trust and eventually begins to develop genuine feelings for him.
  • A similar thing happens in the Supernatural episode All Dogs Go To Heaven a skinwalker disguises himself as a family dog, waiting for the call to attack and turn the family. He eventually grows to love the family, and almost dies to defend them.
  • In an episode of Star Trek: Voyager, the crew finds out that some con artists are impersonating them. One of them, the fake Tuvok, really gets into the role: he seems to sincerely admire the values of the Federation, and is awestruck when he finally meets his counterpart face to face. The real Tuvok is not impressed.

Fake Tuvok: Logic suggests that neither of us has the advantage.
Tuvok: Your logic is flawed (blinds him with a flashlight).

  • In an episode of White Collar, "Forging Bonds", it's shown that Neal went with the alias Nick Halden to work for Vincent Adler. As Nick Halden he meets Kate, and he has a good life going for him, to the point where Mozzie has to keep reminding him about the con he's trying to run. He even blows off the con for Kate at the con's most pivotal moment. He only came clean when Adler conned him out of every penny he had, and that was only because the old life was the only one he had left and he wanted Kate to stay with him.
    • Another episode has Peter going undercover to the point that he starts to really enjoy his fake job.
  • Detective Inspector Zain Nadir of The Bill is warned of how this can occur to undercover detectives who stay in a role for too long. This somewhat happens to him too when he becomes romantically involved with a drug dealer.
  • In the second-to-last episode of Star Trek: The Next Generation, Picard asks Ensign Ro to go undercover with a Maquis terrorist group to discern their true intentions. When she discovers that their intentions, while violent, are no less noble, she starts to sympathize with them, to the point that at the end of the episode, she gives up her commission and joins them, after apologizing to Picard.
  • In the New Tricks episode "Only The Brave" it turns out the murderer was Reverse Mole, Knowles, who had gone native in the gang he was sent in to investigate.
  • In Breaking Bad, Jesse has two of his junkie friends infiltrate his 12-step program to sell meth to the other addicts. They don't have much success. Later Jesse learns that his dealers are actually doing the steps for real and taking pride in their recovery.


  • The song "I Whistle A Happy Tune" from The King and I gives Becoming the Mask a lighthearted approach. The singer advises the listener to make believe they're brave so that they may become brave.
  • The Trans Siberian Orchestra song "Promises to Keep" contains, in reference to the "Christmas Spirit," the lines:

And if our kindness
This day is just pretending
If we pretend long enough
Never giving up
It just might be who we are

  • Melanie Safka's "The Good Guys" is all about this.

You're going to play the good guys
By singing the good guys' hymn --
You're building the halls with the outer walls
But you haven't got a thing within...
Eventually, the whole facade
Becomes more than a whim.
By starting to build on the outside
You're gonna fill up the walls within.

Oral Tradition, Folklore, Myths and Legends

  • One medieval legend is a very literal taking of the trope, that of an ugly man who for years wore a mask that made him beautiful until when he finally took it off he found that his face had grown into the mask's shape, making him truly handsome.

Professional Wrestling

  • Chris Jericho originally set out with Christian to con Trish Stratus and Lita, respectively, into sleeping with them by being lovey, helpful heroes. Along the way, though, Jericho actually developed feelings for Trish and regretted the con, trying to talk his way out of it when the women found out. Trish was already feeling betrayed and well underway with a Face Heel Turn by the time he got around to it, though.
  • During his run as the leader of the Ministry of Darkness, it was hinted a few times that The Undertaker was letting his character completely take over who he really was as a person. In a way, this was strengthening Kayfabe by breaking it.
  • According to kayfabe, "The Boogeyman" was an aspiring television actor who couldn't let go of his commitment to a role after his horror series was cancelled.
    • There were a lot of rumors floating around about him while he was wrestling; dirt sheets commonly reported that he actually did eat worms back stage(he'd eat them in the ring as part of promos to freak his enemies out...or just because) and that he'd stay in character all the time.
  • El Santo. Lucha Libre legend throughout the 50s and until his death in 1984. He became known for his silver mask, which he only removed once for the public eye, and was buried with it on.
  • Rey Mysterio, Jr. too, who in a sense is his mask. In fact, if you saw him bare-faced, you might not even know who it is.
  • The guys behind Wrestlecrap have suggested this is what happened to Jim Helwig, also known as The Ultimate Warrior.

Tabletop Games

  • The Eldar of Warhammer 40,000 deliberately cultivate multiple personalities within themselves and focus on one "Path" of life at a time...because Eldar society that lacked such discipline literally created a god due to their excesses. The Eldar usually take up and cast aside roles as needed, but occasionally get "stuck" in one: Exarchs, for example, are Eldar warriors who become so enamored of violence and bloodshed that they cast aside their old identities and take up the name associated with the armor they wear (which contains the collected spirits of every Exarch to wear the armor). They are viewed with a mixture of awe and revulsion by other Eldar.
    • This is actually literal, since most Aspect Warrior armour features a mask.
  • The Dungeons & Dragons setting Eberron has this as the basis for one of the Changeling philosophies. Natural shapeshifters, Changelings of the Passer philosophy do their best to forsake their true nature, creating an identity of another race and adopting that as their 'true being'. While they can still shapeshift, they are very uncomfortable doing so, or even reverting back into their real form, as their 'mask' becomes their true identity. The other two philosophies are similar; Seekers aim to embrace the 'ultimate form', which they believe to be an extension of the Changeling's true form, while Becomers are similar to Passers, but assume myriad different lives and identities, all equally real to the Changeling.
  • The Promethean Karma Meter represents this: the better they are at acting human, the more likely they are to internalise it. Thus, they have a higher chance of succeeding in the roll to be reborn as a human.
  • Personamancers in Unknown Armies base all their magic around pretending to be other people (or screwing with other peoples's self-identification). They charge their magic through pretending to be other people. Here's the catch: to gain the power for such an act, they have to really believe they're somebody else, at least a little. And gaining recognition as themselves kills their power. One of the quickest ways to gain power is to pretend to be somebody else into a mirror for one hour. Do that every day for years and eventually, you start to buy it...


  • Bertolt Brecht's Man Equals Man is made of this trope. The plot centers on harmless everyman Galy Gay, who runs into a group of British soldiers on the way home from the market. Because they don't want to be punished for losing group member Jeraiah Jip while out drinking, they ask Galy Gay to take his place for roll call. When that's done, the group leader decides to completely change Gay's personality just for the lulz. One fake elephant, staged funeral, and castration later, the new Galy Gay/Jeraiah Jip is enthusiastically leading a savage attack on rebel forces in Tibet. (In the meantime, the old Jeraiah has assumed the place of an oracle at the temple where he woke up hung over.)
  • Charlie Baker from The Foreigner. By the end of the play, Charlie has become the Foreigner to the point that he remains in character around Froggy, the one character who knows he really speaks English.
  • In Martin Guerre, Arnaud du Thil is intitally reluctant to assume the identity of his friend Martin, but as the musical progresses he grows to love Martin's village, life, and especially his wife Bertrande. By the time he is put on trial for 16th century identity theft, he seems to really consider himself 'Martin Guerre' and even sings a reprise of Martin's song, 'I'm Martin Guerre.'

Video Games

  • In Tales of Legendia, Senel infiltrates the village where Shirley and Stella live, acting as a soldier of Vaclav. Senel pulls a Heel Face Turn while there and forgets about his mission, wanting to live in peace beside them. But, that doesn't last.
  • Cait Sith in Final Fantasy VII, who joins the party as a spy and then grows to care about them and joins them for real.
    • Only superficially fits as an example. Reeve was already sympathetic to most of the party's issues, but sincerely did not trust Avalanche. He didn't so much change personality wise, but realize that Avalanche was operating on the same wavelength he was.
  • Leliana from Dragon Age. She was originally basically an assassin, and she had to flee her home country and go undercover. She pretended to be a sweet, bubbly girl with a strong faith in the Maker—then she decided she actually liked the whole "being happy" thing.
    • Morrigan also has some elements of this, pretending to like the male player character in order to get into bed with him and then actually falling in love.
  • The whole plot of Super Robot Wars Advance pretty much revolves around this, depending on who the protagonist is. If it's Axel Almer, he got amnesia after doing the dimension jump to infiltrate the protagonist group and had enough time to befriend them and leave a good impression, and when it came to his time to return, he realized that his group was wrong and elected to stay on the new group, fighting his previous superior. Same thing happened to Lamia Loveless, except that she got no amnesia, but her orders usually come too late, and she already blended with the society, making her realize she has a conscience and values it, thus making her reject the fact that she's a mindless doll and betray her superiors. And the protagonist's reaction to them? Forgiving as ever.
  • Claves in Eternal Sonata was a spy for Count Waltz, but chose to reveal their deception after falling in love. Unfortunately, Redemption Equals Death.
  • Rose in Metal Gear Solid 2: Sons of Liberty.
    • Ditto Decoy Octopus in Metal Gear Solid: According to his bio, he has to undergo psychic therapy after he's done being disguised as someone else, since his disguises are absolutely perfect down to the slightest detail...including blood type and DNA.
      • The guy even files down his cheekbones where necessary to ensure that the shape of his face is the same as his disguise's.
    • And later in Metal Gear Solid 4: Guns of the Patriots, we have Revolver Ocelot, who specifically tricked himself into thinking that he was Liquid by way of hypnotherapy and (what else) nanomachines, so that he could fool the System and gain access to the Patriots' AI.
  • In The Force Unleashed, Starkiller spends time gathering "allies" while pretending to be a Jedi. Over time he begins to make good decisions, and begins to play the part very convincingly. By the time Darth Vader betrays him, he realizes that he IS a Jedi. And goes on to challenge the Sith. He saves the rebels, but it doesn't go well for him.
  • This happens alarmingly frequently to people who play the Spy in Team Fortress 2: While disguised as a member of the opposing team, it's surprisingly easy to forget whose side you're really on, especially since you have to act the part for the disguise to work. It doesn't help that teams are identical, save the color of their uniforms and those often switch do to asymmetrical game modes switching the teams each round and team scramblings.
    • Then there's this comic.
  • Rival Schools pulls this off in both series' games. Kyosuke Kagami's work with Taiyo High in United By Fate convinces him that his twin Hyo's plan may not be the best idea, while Yurika Kirishima's time at Seijyun High (and specifically inspired by her best friend, Akira) in Project Justice moves her to betray her younger brother Kurow.
  • Iris in Phoenix Wright Ace Attorney Trials And Tribulations pulled a Twin Switch with her Evil Twin sister Dahlia to keep her from killing her boyfriend Phoenix, but she came to truly like the guy and couldn't even take the item she was supposed to get from him to keep her sister from killing him.
  • Jansen Friedh in Lost Odyssey starts out as The Mole (as the other party members are perfectly aware of), but it only takes him a day or so of traveling with Kaim and Seth to decide he likes the two of them a lot better than he likes his employer. Falling hard for The High Queen Ming Numara is the final straw.
  • Joshua of The World Ends With You decided to keep Shibuya the way it was after winning the last Game. at the end because of his experiences with Neku.
  • Combined with Manchurian Agent in Tales of Symphonia: Dawn of the New World. It's pretty complicated, but it all boils down to Ratatosk embracing the side of his personality that had originally been a facade and nearly eclipsed his original murderously angry persona.
  • Inverted in City of Heroes when one story arc has you tracking down an undercover police officer who turns out to have fully joined the villain group he was infiltrating.
    • This is possible for the player if you choose to start in Praetoria. You're required to choose a philosophy (Loyalist or Resistance) at the start of the game. Players can choose to do missions for the opposite faction, periodically contacting their faction leader to twist the results one way or the other. As long as you continue to periodically contact your faction leader, you're still considered to be "undercover". However, it's incredibly easy to find yourself "forgetting" to check in with your former faction leader...
    • Vanessa DeVore, leader of the Carnival of Shadows, coincidentally managed to find and put on an actual mask containing the soul of one of her ancestors. At first the two struggled for control of her body, but eventually began to work together, making Vanessa (formerly a normal, non-evil person) a violently hedonistic villain with Psychic Powers.
  • In Prototype, Alex Mercer is quite explicitly dead and gone. However, the corpse was subsumed and reanimated by the Blacklight virus, which imitated him so completely, so perfectly, that The Virus believes it is Alex Mercer. Even after it finds out the Awful Truth, "Mercer" is changed by the experience, evolving from the Complete Monster that Mercer was as a human, to a rampaging sociopath with occasional flashes of heroism, to a Sociopathic Hero, given that he protects New York from being nuked when it would have been far easier for him to simply do nothing and save himself.
  • Also happens a lot in Mitadake High when the Killer/Kira starts befriending others in order to betray them later, and ends up caring about them, and even sparing them at the end of the game. A weirder version can happen when the killer/kira doesn't notice that they are the killer/kira and plays the entire game as if they were innocent.
  • Discussed in The Legend of Zelda: Majora's Mask. One of the children that you play hide 'n seek with at the end of the game questions that, "if you have so many masks, what is your real face?"

"Your true face... What kind of...face is it? I wonder... The face under the mask... Is that...your true face?"

  • Taichi in CROSS†CHANNEL is literally in the 'becoming' part of this trope. He's really trying hard not to be completely insane and connect with people, unlike Youko. The mask slips every now and then, causing all of his relationships to be extremely unstable. The best example of this would probably be the small slipup that occurs right after Yutaka committed suicide and he ruins his relationship with Kiri. She thinks he killed Yutaka, when in truth he didn't really care much anymore. Before and after that, she's probably the only person apart from Youko who truly understands him fully.
  • Kessler in In Famous is unrecognizable as Cole's future self; he keeps a memento to remember his previous life by, but after fifty-plus years of scheming and plotting and acting how someone has to act to reach his position and maintain it, he's not that person anymore.
  • MASK DE Smith from Killer7.On so many levels.
  • Ninja Maid Cecilia of Vanguard Bandits initially hates the whole maid idea. But by the end of the game she's grown to love it so much she gets into an argument about wanting to keep all her maid costumes.
  • Arguably Nick in Left 4 Dead 2. Whilst he begins as a passive-aggressive jerk who admittedly sticks with the others just for safety, he gradually opens up and becomes one of the group.
  • Kingdom Hearts 358 Days Over 2 reveals Saix as a villainous example. He and Axel (who was his best friend before they became Nobodies) were originally plotting to overthrow Xemnas in the event that Xemnas strayed from the Organization's goal of regaining their hearts (a suspicion that is shown to be correct after Saix and Axel both die). Axel's killing of Vexen and manipulation of Zexion's death in Chain of Memories were actually done on Saix's orders. However, due to Axel's friendship with Roxas and Xion, a rift formed between him and Saix, both feeling that the other had changed. As a result, the plan slowly fell apart and by the end of the game, Saix dismisses his previous plan as nothing more than a fantasy.
  • Happens in Ever 17 with Kaburaki "The Kid" Ryougo impersonating Kuranari Takeshi in Kid's (Hokuto's) routes. It's done so well that half of the plot hinges on it, but Kaburaki gets a little bit too intimate with his fake personality. A given, since he's been practicing non-stop since 2017.
  • Margarete in Shadow Hearts talks about this in one scene. She was ordered by the "Powers" (presumably, the French, whom she worked for) to spy on the crisis in Asia, where the game starts. When she meets Yuri, she fully intends to use him to benefit her nation. However, as she worked with him, she grew attracted to his comic book-esque ways. She never follows through with her mission.
  • In Skyrim A wizard sets up a Scooby-Doo Hoax, masquerading as the guardian spirit of a Nordic burial ground to keep superstitious locals from discovering that he's attempting to loot the tomb. After six month of failing to solve a puzzle-locked door, he goes insane and becomes convinced he's an actual guardian spirit.
  • They call me... Prophet.
  • Magical Diary: Horse Hall has Damien nearly done with the con he's been pulling on you all year (and on the school in general for the past four years), only to find out that he can't finish what he started. The realization causes him a few problems.

Web Comics

  • An interesting example occurs with Anevka in Girl Genius. After being damaged in an experiment as a young girl, her body is stuck in a nutrient tank and attached to a Clank that allows her to interact with the outside world. At least, until her brother reveals she died years ago; the Clank ended up developing its own personality and came to believe it was Anevka. In other words, the mask became her.
  • In The Adventures of Dr. McNinja, the title character and his family do this deliberately, from birth. Since no one knows what they look like without their ninja masks, they always have a means of disappearing forever if all hope is lost.
  • There's an interesting mental disorder in Mary Sue Academy called Character Shock Syndrome Sue. It's where a Mary Sue become the character they portray. Jessica Pluto suffers this.
  • The "bad" version happened in the backstory of Juvenile Diversion: Courtney "infiltrated" the cheerleaders to get revenge on them, then promptly became just as much of a bitch as them.
  • In The Order of the Stick, Belkar's 'fake character development' is turning into actual character development, bit by bit, thanks to Mr. Scruffy.

Web Original

  • Tales of MU has Suzune "Sooni" Hoshinotama, who appears to be this in addition to the local Yandere. She sees herself as the lead character in a manga, and expects the world to naturally follow the "rules" of manga plot lines—and then goes into a towering, violent rage whenever the universe doesn't play along. If there's anything behind the mask, it's a very young, very isolated little girl.
  • In Survival of the Fittest version three this happened to Dominica Shapiro, who initially joined the group SADD on the off chance their plan would work, with the intent on a double cross if not, but gradually became more and more part of the group properly.
  • In Chewbot's Let's Play on Oregon Trail, "Plague and Treachery On The Oregon Trail", it's revealed that Susan was a British spy sent to overthrow America from the inside, but she eventually came to love the family she created as a cover, and abandoned her assignment.
  • While everybody in Suburban Knights is trying to stay in-character, several of them do so with more...commitment than others. Obscurus Lupa claims that she should be useless in battle because of her character choice, Paw Dugan tries to |gather rage from everybody (including the trees), and Phelous seems to have gone right off the deep end. Marz Gurl also seems to be joining the throng, what with speaking only in Japanese, scenting the air and biting the Critic on various portions of his anatomy.
  • A fair amount of the My Little Pony Friendship Is Magic fanbase started out as Internet trolls who started pretending to be obsessive fans of the show just to get other people confused and/or irritated. It's My Little Pony, what teenage boy or man could possibly enjoy such a series? Well, as the trolling went on, the majority of them started to find all the little Parental Bonuses and Shout Outs, and of course, Lauren Faust's contributions to the show, making it fun to watch even for the parents of the target demographic (girls aged 5–10). The trolls started legitimately liking the show. Some even stopped their pony-themed trolling out of respect.
  • Dramatic Detective of LIS DEAD admits in the comments of an early post that he identifies himself more closely with some of his aliases than the name his own mother gave him.

Western Animation

  • Shayera Hol aka Hawkgirl of the animated Justice League joined the team as an alien spy, but then decided to stay with them and betray her people.
    • She didn't actually stay with them, but helped them form a counter-offensive, when she found out what her race was really planning to use the Earth as a hyperspace bypass in an interplanetary war, which would destroy it. Feeling guilty of betraying both the Justice League, and her homeworld of Thanagar, she decided to leave the team before they announced their desicion on whether she can return.
  • Terra (in the Animated Adaptation only) of Teen Titans really began to feel at home with the team and fell in love with Beast Boy. She tried to compromise by saving him and letting Slade kill the others, and, well, you can guess how it turned out.
  • Phineas and Ferb: Perry the Platypus was assigned to the Danville residence so that he could have a secret identity as a normal platypus, as he was a secret agent. However, it's shown that he's legitimately attached to Phineas and Ferb, regardless of whether he's a house pet or a semi-aquatic mammal of action.
  • The assassin droid Zeta in Batman Beyond replaced an accountant, as he was investigating money laundering by a terrorist organization. Once he completed the mission he ended up running into the guy he was impersonating. Per protocol, he should have eliminated the man on the spot. The aforementioned time spent with the man's family affected him to the point that he could not bring himself to deprive him of that experience, and so went rogue instead (leading into his Spin-Off series, The Zeta Project).
  • The Legion of Super Heroes cartoon has evil shapeshifter Ron Kar finds himself sympathizing with the good guys, and even willingly helping them, after his Memory Gambit infiltration is exposed.
  • The Looney Tunes cartoon Bugs' Bonnets (1956) plays with this idea by casting it in the form of people taking on roles defined by the hats they wear—and then throwing Bugs Bunny and Elmer Fudd into a landscape littered with hats scattered from a passing truck. How many times—and to what degree—can these two Become The Hat? Needless to say, it gets typically extreme.
  • Taken to ludicrous extremes by Roger in American Dad. He creates a new identity to seduce a shop girl and allow him to steal a pair of gloves he likes. Then the stress of actually caring about someone causes Roger's mind to split into two - the persona he created, and himself. Apparently his persona carries on for quite a while before Roger notices extra bills on his credit card, at which point Roger tries to destroy this man's life.
    • Not to mention the little roleplaying activity that he and Francine improvised for themselves...
  • An episode of Fillmore! has Ingrid going undercover in a close-knit mafia-esque Girl Scout Troop. She genuinely befriends the group, making it especially hard to go through the sting. As an added bonus, their leader was the Safety Patrol's previous undercover agent gone rogue.
  • Seymour Skinner in The Simpsons. In the episode "The Principal and the Pauper", it's revealed that he is actually Armin Tamzarian. He served with the real Seymour Skinner in Vietnam and took over Skinner's identity when he was apparently killed. Twenty years later, the real Skinner shows up in Springfield to reclaim his identity. But the townspeople decide they prefer to keep the Skinner they're used to. The real Skinner is banished from town, Tamzarian is put back in Skinner's identity, and it's ordered that nobody will ever mention this incident again.
  • South Park. Cartman. Tourette's. Originally so he could say antisemitic things on Dateline, but it became "My cousin and I touched each other's wieners!" and "I wet the bed!"
  • Brock Samson of The Venture Brothers He was originally assigned to prevent Rusty Venture from ever activating the ORB and was put under the guise of the Venture family's bodyguard, but after several years of protecting them he truly began to feel like part of their family, and even purposefully refused to kill Rusty when he discovered the ORB.
    • It's heavily implied that until that episode, Brock didn't know what his real mission was.
    • Also his predecessor that protected venture's ancestor. He broke/damaged the ORB to the point it would never work instead of killing him. Leading to the events of the episode.
  • In the first Daria movie Is It Fall Yet her mother cites this as the reason for forcing her to volunteer at a youth camp.
  • An Alternative Character Interpretation of Mother Gothel from Tangled has her think she might have become the mask. However; many of the indications that she did at some point were subtle, but effective.
  • In one of the old Tom and Jerry episodes, a duckling comes to think of Tom as his mother. At first, Tom is only taking advantage of it to prepare to cook the little duckling into stew, but by the time the duckling willing decides to do it, Tom can't bring himself to cook the little guy and saves him. Also one of the few episodes that ends with Tom having a happy ending.
  • Family Guy: Peter pretended to attend Meg's high school to discourage the students from licking toads, but he eventually started thinking he was a real teenager.
    • Also occurs in the episode Brian writes a bestseller: Though his original intention was to write trash out of sheer frustration, the work began to garner fame and appreciation from the looked-down-at people and he started to really believe he was a genius, and he had created a life-changing masterpiece.
  • Zhalia from Huntik Secrets and Seekers at the end of episode 17.
  • Did no one mention Smurfette yet? She is created by Gargamel to infiltrate the Smurf's village, but when they find out thanks to her almost drowning them with the water from the dam, Papa Smurf turns her into a real smurf. A fitting mask, wouldn't you say?
  • Subverted on the most recent season finale of Aqua Teen Hunger Force, where the Teens were revealed to be secret agents of some sort and Carl was a secret agent assigned to spy on them. At the end of the episode, he mixes up strip club and liquor store, implying that the real Carl does not share the *ahem* interests of the Carl we've come to know and love. Of course, given what show we're talking about, don't expect this to carry over into next season.

Real Life

  • The Edwardian Country House: The Olliff-Cooper family quickly adopts the lifestyle of the upper class despite knowing it is reality television. [1], [2], [3], [4]
  • This is literally Psychology 101 material. When you act out a role, it naturally becomes less and less of an act, as seen with method actors and army drill sergeants. Everyone does it to some degree.
    • On the subject of psychology, this happened to psychologist Philip Zimbardo during his famous Stanford Prison Experiment. The realization that he was beginning to think like one of the sadistic prison guards he was trying to learn about was part of his motivation for ending the controversial experiment early.
    • His book, "The Lucifer Effect," which has several chapters focusing on the experiment, confirms that it was his girlfriend that made him realize he was becoming too involved as the 'Superintendent' of his 'prison' after a massive argument. He terminated the experiment the next day. At the rate prisoners were being released early, though, the experiment could have been terminated prematurely even without the argument, possibly.
    • Psychological/Sociological research based around participation/observation has a term for this: Going Native.
    • Something similar happened during the Third Wave experiment, in which the teacher became a Hitler-like figure.
  • The late great Peter Sellers had said on numerous occasions "There is no 'Me'; I do not exist." Beyond just being a great actor, he literally could become his role and have a bit of a hard time shaking it. The great Sir Alec Guinness and legendary Lon Chaney Sr. were said to have similar psychologies.
    • Heath Ledger was also rumored to have that psychology.
  • A Russian Intrepid Reporter, Yaroslava Tankova, was making a series of articles about Gold Diggers in 2008-2009, by pretending to be a Gold Digger and infiltrating their communities. In the last article she admitted that she almost wanted to give up journalism and become one.
  • Social Constructionist theories of society claim that any aspect of society (education, religion etc.) only has a function because it is ascribed by the population. A kind of Becoming the Mask for concepts.
  • CS Lewis said in the preface to "Screwtape Proposes a Toast" that while lots of people requested a sequel to The Screwtape Letters, for the longest time he refused to write one because even though the original book was the easiest thing to write that he had ever produced in his life, it was a horrific and stifling experience to have to make himself think like Screwtape and basically become a demon.
    • He also said that those who are afraid that they can't "love their neighbor" should just act as if they did and the rest would take care of itself.
    • Lewis loved this one. He said that the whole point of ritual and formalised prayer was that you could 'dress up' as a saint - and thereby become one.
  • In World War II, after the Italians turned against the Nazis, the Germans coached an Italian petty thief to pose as an aristocratic Italian general and convince several captured resistance fighters to spill their secrets. He set out instead to be an inspiring figure who'd help the men hold onto their information and their pride. When the Germans executed him for betraying them, he died still maintaining the false identity. This was made into a movie, General della Rovere, in 1959.
  • In Model UN (and similar programs), enough time representing the same country/person (or ones with similar views) can start to do this to you.
  • ATF agent William Queen spent two years undercover as Billy St. John, a member of the Mongols motorcycle gang, and admits he grew to liking the gang he was in and found them kinder than many law abiding folks he knew. He felt somewhat sorry for turning them in when his job investigating and spying on the gang was over.
  • One explanation for leftwing agitator / Con Man Ward Churchill (best known for writing an inflammatory essay praising the 9/11 hijackers, or at least villifying the people they killed and claiming the incident as a legitimate act of war) posing as a Magical Native American for several years and gaining a university professorship as part of some kind of affirmative action-type scheme. He claimed he'd originally planned to admit the ruse as soon as he got the job in order to point out the inherent racism of the university's hiring practises and the government's various "Indian Affairs" schemes, but found himself growing into the role and believing he could do more good as a teacher. The fat paychecks he was getting from the school probably had a lot to do with it, too, though.
  • Becoming the Mask is arguably a component in Stockholm Syndrome, since the captive or victim, if they want to come out of their situation unharmed, would first have to unwillingly act cooperative before showing true attachment.
  • In The Chrysanthemum and the Sword the Japanese code of honor is described as being like this.
  • Joe Pistone, a.k.a Donnie Brasco, would arguably qualify as a subversion. While he admits he retains some "wiseguy" habits from his six-year undercover stint and felt some closeness to mob mentor Sonny Black, his daily interactions with real-life Mafiosi more or less reinforced his negative view of the Mafia and its members.
    • While it is not unheard of, despite the trope's popularity, undercover agents and officers undergo extensive psychological testing, and extensive training, specifically to avert this trope. Unfortunately for Pistone, he went deep cover before any of this and had to rely on his own values.
  • On the positive end, one of the tenets of Alcoholics Anonymous is "Fake It Till You Make It": By forcing yourself to act a certain way even if you don't like it, it eventually becomes a habit.
    • This method is also used to combat depression. By acting as if you're happy, even though it feels forced at first, you will eventually become happier.
  • Another positive example, any Real Life Stepford Smiler. Facial expressions usually portray what a person is feeling, but it's a two-way street. If a person fakes a smile (or a frown) their mood will be effected accordingly, even if it's only a little bit. Try smiling right now, you'll feel better!
    • Just as forcing a smile can make one feel better, holding back a smile can lessen the impact of happiness. People who freeze their faces with anti-wrinkle chemicals such as Botox are shown to not feel as sad or as happy as other people.
  • Lalla Ward once said in a Doctor Who Magazine interview that the reason she and Tom Baker got married was because they played the Doctor and Romana Like an Old Married Couple, and then mistook that for actually being in love.
  • Rye and oat were originally weeds in the first wheat and barley fields. To survive cultivation these weeds had to become more like domesticated cereals. When agriculture expanded to places where wheat and barley did not grow well, rye and oat had become enough like crops to be successfully farmed.
