Luke, I Am Your Father

 Lbjru5CQIW4 A specific variety of The Reveal.

A parent-child relationship between two characters who were previously thought unrelated is revealed, usually with generous dollops of melodrama—blood is, after all, Thicker Than Water. Beloved of soap operas, made famous by the Star Wars films (from which the trope takes its name, though as you can see, it isn't an exact quote). Whether or not this is a good thing or a bad thing for whoever is being given the reveal mainly depends on who is giving the reveal in question. Sometimes an ally, a Mentor or a non-romantic Mysterious Protector will turn out to be the parent of the person being given the reveal, but other times, the reveal of who a character's parent is will be cause for serious anguish, such as someone who just gave his or her life for him, someone who could have been a Love Interest, or worst of all, a villain working for the Big Bad or even the Big Bad himself, as in the most infamous Star Wars example.

In cases when villain and hero turn out to be parent and child, count on at least one scene where the hero worries that he or she will eventually end up like the parent.

Sometimes it's a bogus revelation, and at the end of the episode or plotline the Reset Button is pressed to restore the previous relationship—or lack of one.

Though the trope itself is too fundamental to become Discredited, any use of the actual line nowadays will be met with a groan and a "Not again!" from the audience. Also a popular insane fan theory.

Compare with Mysterious Parent, or Family Relationship Switcheroo where the characters were thought to be related, but are not parent and child. Frequently, it's a father-son relationship revealed this way.

This trope was already being mocked back in 1790 by Jane Austen in Love and Friendship (with four grandfather-grandchildren relationships revealed in under a page).

Compare Long-Lost Relative, Luke, You Are My Father, Luke, I Might Be Your Father, Everyone Is Related. Contrast with I Am Not Your Father.

Comic Books
"Tyler Stone: And you will do it... because I'm your father. Miguel O'Hara: (sips coffee) Yeah, I know. Tyler Stone: You... you know? Miguel O'Hara: Yeah. Now get out of my office... dad."
 * Eighteen years after their creation, it was revealed that Avengers Scarlet Witch and Quicksilver were actually the children of their former leader, long-time X-Men antagonist Magneto. Their feelings over this revelation were mixed, to put it mildly.
 * Polaris, of the X-Men, was revealed early on to be . But then that was revealed to actually be a plot by the villain . Then later it was again revealed that she is ... . Currently, she is once again ... ugh.
 * A Legion of Super-Heroes mini-series in the '80s started with the premise that R. J. Brande, the team's billionaire sponsor, was dying, and in order to save him, the Legionnaires had to figure out which one of them was secretly his child—an idea that had never been even hinted at before. It finally turned out to be Durlan shapeshifter Chameleon Boy; Brande was revealed to also be a Durlan who'd contracted a disease that froze him into human form.
 * Chris, Superman's adopted son, was found in a rocket similar to his. It was revealed during an invasion that
 * Mr. Sinister pulls a particularly unpleasant Luke, I Am Your Father on Gambit in X-Men: The End when he reveals that Gambit is a clone created from Sinister's original DNA mixed with that of Scott Summers.
 * Gladly, this probably isn't canon, the Summers have a messed up history as it is.
 * In Booster Gold One Million it is revealed to the audience—but not to any of the other characters—that.
 * The plot of Batman R.I.P. essentially involves multiple Mind Rapes piled on top of each other to see how many it takes to make Batman crack. The biggie? Enigmatic villain Simon Hurt claims that he is actually Thomas Wayne, and that he faked his own death after hiring Joe Chill to kill his faithless whore of a wife. The truth of his story hasn't been determined, but Bruce decides to reject it at the end of the arc.
 * There are strong hints in Batman R.I.P. that Hurt is actually
 * But if you paid enough attention to the first few pages of the chapter Midnight in the House of Hurt, Dr. Hurt made arrangements for a false suicide note, doctored documents and phony witnesses for a recent victim that was killed by one of his associates. Apparently, it's not enough for the doctor to ruin and leave you as a empty, broken shell of a man after one of his twisted games in the Black Glove; when you're killed, he makes damn sure you'll be remembered as a chronic junkie, a horrible pedophile or worse. His claims that he's Batman's father and his family's "dark history" is a last attempt to screw Bats over and coerce him to join the Black Glove as his Evil Plan was crashing down like a house of cards.
 * Ultimately, it turns out Hurt is
 * Preacher:
 * In Umbrella Academy: Dallas #6, it's revealed that
 * Rose Walker's grandfather in Sandman is Desire, who impregnated the comatose Unity Kinkaid during Dream's imprisonment.
 * A pivotal turning point in the original Spider-Man 2099 run featured Miguel O'Hara (Spider-Man) discovering that the main antagonist of the series and head of the megacorp Alchemax, Tyler Stone, was in fact his father. This derailed the current plotline for quite a few issues as Miguel wrestled with his hatred of the man. The trope was lampshaded near the end of the title's run, when Tyler attempted to shock Miguel into following his orders by dropping the bombshell of his parentage, only to have Miguel, who by this point had come to terms with the fact, casually sip his coffee and then smugly and calmly reveal that he knows.

"Buzz: Dominique... I am your father... Oh, I'm certain that didn't sound too "Darth Vader"."
 * Tossed in a blender with Luke, You Are My Father (but not really) in Usagi Yojimbo: TL;DR: Father A and Son B know they're related, but they don't know the other knows the truth (C,D,E, and F know the truth too but they aren't talking, mainly out of respect).
 * In Green Lantern Corps #35, Sinestro tells  that she is his daughter. He left her in the care of her foster family to keep her away from the dangers of being associated with him; making this one of the only semi-decent things he's ever done in his life. Since it's Sinestro, he could be lying.
 * The last page of Green Lantern #36 makes it pretty clear that he's telling the truth.
 * Watchmen has a particularly twisted example of this. Laurie, the second Silk Spectre, discovers that the recently-deceased Comedian tried to rape her mother, the first Silk Spectre. Then Laurie finds out that after the near-rape, her mother had consensual sex with him anyway, and that the Comedian is in fact her father.
 * In Batman/Huntress: Cry for Blood, Huntress gets an old photo of her deceased mother, Maria Bertinelli, in flagrante delicto with mob boss (and rival to mob boss Franco Bertinelli, Maria's husband) Santo Cassamento, and demands to know what they were doing in that hotel room together. His answer: "Isn't it obvious? We were conceiving you, Helena Rosa."
 * The original Gen 13 had more of a "Luke You Are His Father", with Burnout and team mentor Lynch simultaneously learning that the former is the latter's long lost son.
 * Lampshaded in Peter David's Supergirl #57:

"Hiro-Kala: Who are you? Banner: Your...your father. Hiro-Kala: Hmp. I don't think so. Banner: Yeah, I'm not too happy about it either."
 * In nine issues, Brightest Day has already had three separate revelations about familial bonds between heroes and villains.
 * Hiro-Kala knew that he was the son of The Hulk. He didn't know that Bruce Banner was the Hulk. So when they first met, the following exchange happened:


 * In the Sonic The Hedgehog comics, Knuckles' girlfriend Julie-Su discovers that she's the half-sister of Dark Legion leaders Kragok and Lien-Da, which also makes her a descendent of Knuckles' ancestor Dimitri (making her and Knuckles very distant cousins). And sometime later, it's revealed that  is Kragok's son.
 * In a dark alternate universe, 30 years in the future, Lara-Su was raised to believe her father Knuckles had been killed by Constable Remington. However, after she goes back in time (and travels to the wrong dimension too), her mother Julie-Su finally tells her that, in fact, Knuckles wasn't killed by Remington, but went insane with Chaos Powers and became the dreaded leader of the Dark Legion and by extension tyrant of the entire planet, Enerjak.
 * Pre-Flashpoint, Wonder Woman discovered that one of the Hechatonkaires was her "father": the clay that was used to create her came from his imprisoned body.

"Ashura: I am your father Luke -- I mean, Shadow. Shadow: Shut up with the clichés already! You're not actually my biological father, are you? I saw that movie. I'm not going to do that stupid NOOOOOOOOOO thing."
 * A hand-full of Harry Potter fics. A lot of Snape fans enjoy writing stories in which Snape is revealed to be Harry's biological father. Ether Lily cheated or her whole marriage to James was a big, complicated ruse. Harry's reaction varies, but anger at being placed with the Dursleys when he had a living father the whole time is common.
 * Lampshaded in A Rose and a Thorn 3.

"Zurg: Surrender Buzz Lightyear! I have won! Buzz: I'll never give in! You Killed My Father! Zurg: No Buzz, I am your father! Buzz: NOOOOOOOOOOOOO!"
 * Parodied in Toy Story 2 with a Buzz Lightyear action figure and his archnemesis Evil Emperor Zurg reenacting a slightly modified version of the Star Wars reveal.

"Luke: I'll never join you! You Killed My Father! Darth Vader: No, Luke... I am your father! Luke: That's not true! That's impossible! Darth Vader: And Princess Leia is your sister! Luke: That's not true! That's... (bewildered) improbable! Darth Vader: And the Empire will be defeated... by Ewoks! Luke: (totally lost) That's... very unlikely. Darth Vader: And as a child, I built C-3PO! Luke: Huh? (later, with Vader sipping coffee and Luke smoking a cigarette) Darth Vader: (matter-of-factly) And the Force? Well, that's just microscopic bacteria in your bloodstream called midichlorians! Luke: (getting up, disgusted) Look, if you're not gonna take this seriously, I'm out! (exits)"
 * As mentioned above, everybody knows about The Reveal from the second part of the original Star Wars trilogy. The reason that this reveal worked and a lot of the imitators fell flat was that a big part of Luke's story revolved around his Jedi Knight father, whom he sought to emulate as a Jedi himself, which was why Luke let out the Big No in response to the Awful Truth about said father being revealed. It also gives new light to Uncle Owen's reasons for refusing to let Luke accept the Call to Adventure, in particular his "That's what I'm afraid of" response to Aunt Beru's assessment that "he's got too much of his father in him."
 * The lesser reveal in Return of the Jedi, that Leia is Luke's sister.
 * Parodied in Thumbwars: "Luke... I am your MOTHER!"
 * Robot Chicken has Vader reveal that as well... and that the Empire would be defeated by Ewoks! And that as a child, he built C-3PO!

""I mostly was upset with the cavalier attitude towards Boba Fett. He had been built up as this monumental bounty hunter, and he... just flies away. I thought that was going to be a major revelation, off comes the helmet, oh my God, it's my mother! She's a double agent working for the good guys, who knows.""
 * Also parodied in Darths and Droids, using Anakin's stepfather in the second episode. Naturally, Anakin says a Big No.
 * Darths and Droids later did the "I am your mother" bit, here
 * The line itself, the Trope Namer, is actually a Beam Me Up, Scotty.
 * In an interview with CNN, Luke's actor Mark Hamil expressed his disappointment about the role of Boba Fett in this way:

"Dark Helmet: I am your father's brother's nephew's cousin's former roommate! Lone Starr: What does that make us? Dark Helmet: Absolutely nothing, which is what you are about to become!"
 * Certainly that would cast Fett's "As You Wish" from The Empire Strikes Back in a completely different light. It would screw up canon so much; the Retcon attempts to make things fit together would be magnificent.
 * Parodied in the second Austin Powers movie with Dr. Evil claiming to be Austin's father (in an exaggerated voice akin to Vader's) and then admitting almost immediately that he was just making it up.
 * In a twist, the third movie features the revelation that.
 * Parodied in Spaceballs:

"Mitch: That's you and my Mom!... having sex! Sam: You were unfaithful to my mom! Pops: No I wasn't. Who do you think took the picture? (later) Sam: Hey, Mitch, remember when you had sex with my sister?"
 * In the movie The Boondock Saints, the hitman known as Il Duce, who previously gave the MacManus brothers the fight of their lives, is revealed to be their long-lost father when he walks in on them delivering the family prayer to their fallen comrade Rocco (whom he had previously been hired to kill) and finishes the prayer himself.
 * And then much ass was kicked.

 * In the film Wanted, this is used as the twist about 3/4ths of the way through the film. It actually makes sense, because it's the only reasonable explanation for why
 * The big reveal in Angel Heart ; in a rather bizarre set of supernatural circumstances.
 * Taken to ridiculous extremes in Dirty Work. Mitch and Sam are talking to Sam's father, Pops, who reveals he's also Mitch's father. They don't believe him; so he pulls out a locket:

"CLU: I'm not your father, Sam. But I'm very, very happy to see you."
 * Subverted masterfully in the movie Pirate Radio, through out most of which it is implied that Quinten is Young Carl's father, only for it to be revealed by Young Carl's mother that  Quaintly enough, Young Carl?s reaction is eerily similar to that of the trope namers.
 * The 2002 adaptation of The Count of Monte Cristo has.
 * The Man From Earth:
 * Before dying at the end of The Man in the Iron Mask, D'Artagnan barely has the time to reveal to Philippe (and Louis) that he is their father.
 * Near the end of Big Money Rustlas, before dying of a gunshot wound inflicted onto him by Sugar Wolf, the film's villain, Big Baby Chips, reveals to Sugar Wolf that he is actually his father, Grizzly Wolf, prompting Sugar Wolf to rub off his face paint to see if he was telling the truth.
 * Inverted in Tron: Legacy when Sam Flynn finally finds his lost father on the Grid, it turns out only to be a program written by Dad, though the dialog is almost verbatim.


 * Candyman Farewell to The Flesh has the main protagonist Annie discover that.
 * The Terminator: Kyle Reese is John's father by Time Travel.

Literature

 * Inverted in the Prydain Chronicles, where Taran goes on a search for his parents. He encounters a crippled shepherd who reveals that he is Taran's father
 * Inverted again at the end of the series, when
 * Terry Pratchett does a great job of Lampshade Hanging on this one in the Discworld novel Maskerade. In an early scene, Nanny Ogg explains the plot of the opera La Triviata to Granny Weatherwax thusly: "Well, there's a lot of humorous dressin' up, etcetera, someone will probably turn out to be someone's long-lost father or somethin'..." Near the end of the book, it is revealed that the star singer in the production of Il Trucadore really is the long-lost father of a young man in the audience. When Agnes (the junior witch) complains "This sort of thing does not happen!" the more Genre Savvy Nanny replies, "Happens all the time in opera."
 * A more interesting variation happens in Thief of Time. First, Susan has to . Later, she For that matter, Susan's discovery that, almost qualifies but fails the "met before" requirement.
 * Subverted in Witches Abroad, where.
 * This happens not once, but twice, and to the same character, in Ann Radcliffe's 1796 Gothic novel, The Italian. In the first instance, the evil monk Schedoni is about to murder the virginal heroine in her sleep when he happens to glimpse her locket—her ownership of which reveals that she is (gasp!) his long-lost daughter!... Only, turns out she isn't. Still, it was a pretty good reveal, wasn't it? She actually turns out to be the long-lost child of a nun who was nice to her earlier in the book, and to whom she'd previously felt a "mysterious connection."
 * Even though it turns out that Schedoni isn't Elena's father,
 * The Inheritance Cycle:
 * In The Wild Hunt Trilogy, 's father is revealed to be , seduced at age 14 by her mother to appease her Complete Monster husband's demand for an heir.
 * His Dark Materials:  Though this could be seen as a rather knowing use of the trope, given that the reveal occurs unusually early in the story. In the film adaptation, on the other hand, it appears in the typical place as a third act plot twist.
 * In Robert A. Heinlein's short story All You Zombies, the main character is revealed to be
 * In Terry Goodkind's Wizard's First Rule, the first book of the Sword of Truth series, it is revealed that Richard is actually the son of Darken Rahl, the antagonist. Yes, his name is Darken. And he's the father of the protagonist, who has a magic sword, and is taught by an old man. This editor would have blanked it out with spoiler tags, but frankly it's not that important. And it's not even the father revealing it to his son, but his son's maternal grandfather. So.
 * This then happens several more times with different characters.
 * The TV series loosely based on the books also follows the trope but replaces Luke, I Am Your Father with, and this time, Zedd is not the one who reveals the truth. The substitution is likely because the actor playing Rahl is much younger than the character in the novel, making Richard only about 10–15 years Rahl's junior in the show.
 * This is actually one of Goodkind's better instances of Playing with a Trope. It starts with Darken Rahl accusing Zedd of being Richard's father. Zedd responds, in short, "Actually, I'm his grandfather. Remember how you raped my daughter? You're his father." Richard is not present for this scene, and doesn't find out himself about either of these relations until the next book.
 * Charles Dickens had a thing for lost parents.
 * In Great Expectations,
 * In Bleak House,
 * In Nicholas Nickleby,
 * In Oliver Twist, . (The musical Oliver! simplifies matters enormously by .)
 * The best Dickensian example of this trope is in Barnaby Rudge, in which turns out to be Barnaby's father. He even reveals this using the phrase "I am your father". If only he'd said "Barnaby, I am your father" it would be perfect. Being simple-minded, Barnaby doesn't react with the same horror as Luke.
 * Done intelligently in Rafael Sabatini's romantic historical adventure Scaramouche: André-Louis Moreau spends most of the book as the nemesis of the abhorrent Marquis de La Tour d'Azyr, who —but Andre-Louis has never particularly cared for anyone except his Parental Substitute; and the fact is resolved within a couple chapters.

 * In Meredith Ann Pierce's Firebringer trilogy, Jan, the lead character and prince of the unicorns (all the main characters in the trilogy are unicorns), discovers in the third book that . Lucky thing then that.
 * Another Meredith Ann Pierce example: the white witch Oriencor is actually the daughter of . Her excuse for becoming the Big Bad was that she felt cheated of her inheritance  . The heroine of the trilogy, Aeriel, also has one: raised an orphaned slave in the land of Terrain, she later discovers she's

 * In the Animorphs supplemental novel The Andalite Chronicles, we find out that

 * In The Night Angel Trilogy, the Godking does this to both the protagonist and someone else. In the protagonist's case, the Godking is just screwing with his mind. In the latter case,.
 * In The Last Book in the Universe, Spaz finds out from Ryter in the final moments of his life that.
 * In Christopher Moore's Fool, titular character and king's fool Pocket learns that his father was, since   made him rape Pocket's mother. Uh-huh. (This means he's been  .)
 * Done twice in Karen Miller's Godspeaker Trilogy. In Dmitak's case it's.
 * Inverted (and partly subverted) in Robin Hobb's Tawny Man Trilogy where the main character is forced to interact with his children, who doesn't know who their real father is.
 * In the first book of Richelle Mead's Dark Swan series (Storm Born), it is revealed, fairly early on, that is Eugenie's father. On a slightly different note, it is also revealed, much later on - close to the very end of the book, in fact - that  is her.
 * In the third book of the Maximum Ride series, Max is horrified to learn that the is her mother. Later, Jeb informs her that this is a lie and  is her real mother. She takes this revelation much better, though is just as shocked.
 * In the Brother Cadfael novel The Leper of St. Giles by Ellis Peters, the titular leper turns out to be . Subverted in that, while he admits the truth when Cadfael confronts him about it, his leprosy has disfigured him so badly that he refuses to reveal himself to anyone else, not wishing to be a burden or to spoil tales of his Heroic Sacrifice.

 * Near the end of Hannah Tinti's The Good Thief, Ren discovers that he is the son of  and   That last is a big maybe, however.
 * In Villains by Necessity, it turns out near the end (hinted at earlier subtly
 * Played with in Brandon Sanderson's Mistborn. Main character Vin knows from the beginning of the story that her father is an important nobleman (she inherited her powers from him), but doesn't know his identity. He turns out to be Tevidian, High Prelan (priest) of the Corrupt Church and right-hand-man to the Lord Ruler. Surely this leads to a dramatic moment where the rebel Vin confronts and defeats her badass Dragon father? Wrong- when we meet Tevidian, he turns out to be a coward who toadies to the Inquisitors (the real Dragons) and gets killed offhand for essentially annoying them without ever getting a chance to speak with his daughter. But honestly, nobody was really that torn up about it.
 * Parodied in the Night Angel trilogy, in which the Godking claims to be Kylar's father, then admits he was joking in the very next sentence.
 * The Lost Symbol:

 * In L. Jagi Lamplighter's Prospero in Hell, Miranda learns that her mother was not who she thought she was. (Her half-siblings let it slip, not realizing she doesn't know.)
 * Played with for Mareth, the young Druid-in-training in First King of Shannara, has revealed to her during the course of the journey that the innate, nearly out-of-control magic she possesses was inherited from her father--a Skull Bearer. She has the appropriate reaction, and almost succumbs to a Heroic BSOD until Kinson Ravenlock snaps her out of it. In the end, however, it is never revealed if this was actually the truth, or part of a trap by the Genre Savvy Warlock Lord to ensnare her powerful magic through her longing for her Disappeared Dad.
 * In The Mysterious Benedict Society, Kate's Disappeared Dad is revealed to be
 * Its played straight in On the Jellicoe Road with Taylor, who finds out who her dad is  and her aunt  . This is played with for Jessa; Taylor (a third party) finds out her father is   late in the story but its unclear if Jessa connects her dad to.
 * Inverted in Dune, as it is actually Alia Altreides who reveals her relationship to Harkonnen,, and it is actually Harkonnen who is shocked at the lineage.
 * In Stephen Hunt's The Rise of the Iron Moon, is astounded to recognize his own features in his daughter; he had seen her mother fall, with a head wound, in a fight.
 * An example from Harald: Though the individual characters know the relationship from the beginning, King James is lead to believe that Harald will join him against Carala, and he gets this sort of surprise when Harald reveals that he's her father.
 * In Harry Potter and the Prisoner of Azkaban, Harry learns that Sirius Black is his Godfather. Predictably, Harry breaks down upon this discovery, not just because one of the most wanted criminals was his godfather, but that he was also his parents' friend and had betrayed them to Lord Voldemort, with Harry deeply considering killing Sirius Black to avenge them.
 * In the Alcatraz Series, Alcatraz Smedry learns that
 * Boneshaker: Dr. Minnericht is said to be the (supposedly) dead Mad Scientist father of one of the main characters.

"Patrick: You killed my erection! Melty Man: No Patrick, I am your erection!"
 * Star Trek: Deep Space Nine: It was hinted at throughout their character arcs, but nevertheless was a huge surprise when it was revealed that Enabran Tain and Elim Garak were father and son. However, Tain and Garak both knew it all along. The reveal was mainly for the audience who had not known it. The drama of the reveal is based on the fact Tain's on his deathbed wants Garak to avenge his death. Garak wants, for once in his life and before it's too late, for them to have a moment as father and son instead of a superior and inferior officer or a mentor and his protégé.
 * Carnivale Where to begin?
 * Lost:.
 * In season 5,
 * Parodied in the Stargate SG-1 episode "200": the rest of the SG team momentarily trick Mitchell into believing that O'Neill is his father by means of Time Travel.
 * Then again, all the numbers work out, those are some good arguments they give, and they never tell him they were joking. Who knows?
 * Well since Mitchell is Acting for Two with his grandfather, it doesn't seem likely.
 * Most folks have two grandfathers. Unless they're Fry.
 * It's made clear that the aforementioned grandfather is his paternal grandfather, therefore O'Neill can't be his father. Plus, O'Neill knew fully well during his time-travel experience that he shouldn't meddle with the past, so he's not going to do something like that. He knows how much it could screw up the timeline.
 * Sanctuary: While the audience learns in episode 1 that  she doesn't get the news until later in the season when he kidnaps her.
 * The second-season finale of The Pretender: Miss Parker learns that she has a twin brother she was never told about because he supposedly died at birth—and not only is he still alive, he's one of the recurring characters! (All four of the series' season finales feature a "He's the brother you never knew you had" reveal for one of the lead characters—counting the clone in the third season finale as a brother—but this is the only one where the brother is an already-established character.)
 * The X-Files: Hints had been dropped throughout the series that Bill Mulder was not Mulder's father, but that his father was C.G.B. Spender. It was left up in the air until season seven's "The Sixth Extinction: Amor Fati", we find out that he is Mulder's father, but Mulder does not find out until much later.
 * The Mystic Knights of Tir Na Nog: Maeve, the Big Bad, reveals she is The Chosen One Rohan's mother. There is no indication at what point she learned this; Maeve seemed as shocked as anyone when Lugad told her Rohan told him they were brothers. The line is almost identical to the movie's with the names changed appropriately.
 * Power Rangers has been fond of this one and uses it regularly since it was so successful the first time around:
 * In Power Rangers In Space, we are treated to the tasty reveal that Big Bad Astronema is The Captain Andros's sister Karone after brainwashing.
 * Two years later in Power Rangers Lightspeed Rescue, we are treated to the revelation that then-evil Sixth Ranger Ryan is Mission Control Captain Mitchell's long-lost son (And, thereby, Pink Ranger Dana's brother).
 * In Power Rangers Ninja Storm, we find out that Big Bad Lothor is Sensei Watanabe's twin brother, and Sixth Ranger Cam's uncle. This was fortunate for Lothor's nieces by marriage, as they would have been destroyed if Cam hadn't decided to save them—because "they're family."
 * In Power Rangers Dino Thunder, we have the revelation that Sixth Ranger Trent is the adopted son of Big Bad Mesogog's human counterpart Anton Mercer.
 * But the all-time leader is Power Rangers Mystic Force, where we learn in short succession that the evil Wolf Knight Koragg is the mind-controlled form of Leanbow, husband to The Obi-Wan Udonna. Udonna then discovers that Red Ranger Nick is actually her long-lost son Bowen. Meanwhile, we discover that comic relief character Leelee is secretly the daughter of Necrolai, queen of the vampires.
 * It would have helped if they hadn't been playing what sounds like a fantasy-sounding version of the theme from the Star Wars prequels throughout the season. Unlike Luke, however,.
 * Following In Space's example, RPM reveals that Dark Action Robot Girl Tenaya 7 is actally Dillon's missing sister, which surprises... absolutely no one.
 * Parodied on The Brak Show episode "All That I Desire You", itself a complete send-up of soap operas; Dad is revealed to be living a double life as billionaire oil baron Drake Gainway, and is father to Zorak, Clarence, and his secret third wife Cynthia - in addition to Brak and the Gainway children.
 * And just for extra craziness, when The Brak Show was "hosting" Adult Swim's New Year's Night, it was revealed that Thunderclese's father was none other than Frylock from Aqua Teen Hunger Force, a completely different show.
 * In series 7 of Red Dwarf it is revealed that Lister's father is.
 * Catherine Willows on CSI, when she finds out that Sam Braun is her father.
 * In the series Heroes, Claire is revealed to be
 * The earlier reveal, when HRG/Noah comes home and we find out that he is Claire's father. (He adopted her, but she considers her adopted parents her "real" parents)
 * And in the Season 3 premiere,
 * Not so much...
 * There's also rumours of yet another Petrelli on the way. I'd guess Adam, but I don't know.
 * Adam's impossible as he's been around for hundreds of years and looks nothing like the Petrellis. Matt Parkman on the other hand... though his dad, Maury, has already been a character, but we don't know if he's not a HALF brother...
 * On the subject of the "new Petrelli",
 * Also as of season 3, Claire is revealed to also be related to Though it's as yet unknown to Claire, it will most likely comprise a bit of a surprise at least.
 * Seriously, is there anyone on that show who isn't related?
 * I've heard rumors about Ando.
 * Strongly hinted in the Law and Order: Criminal Intent episode "End Game."
 * In Remington Steele, Steele finds out in the last episode that Daniel Chalmers, his mentor and fellow con-man, is actually his long-lost father.
 * Subverted in an episode of Las Vegas where Mike finds evidence that the Montecito's new owner, AJ Cooper, is Piper's father. Piper confronts Cooper and he vehemently denies it. It turns out that
 * Also subverted in Life On Mars, where DCI Morgan takes Sam to a graveyard..
 * In US version of "Life On Mars", the trope is inverted:.
 * In the series Night Court it is revealed after several seasons that Harry's.
 * Parodied by the Melty Man (an Anthropomorphic Personification of male impotence, complete with black glove and Darth Vader voice) in Coupling.

"Fry: The truth is, mate, I was confused and slightly bewildered. I'd just discovered that Durnick isn't my real father. Laurie: He isn't? Then who is? Fry: I am. Laurie: Then that must mean that you must be-- Fry: Exactly. Devlin's half-sister's wife's doctor's cousin's niece. Laurie: Well then, who the hell am I?"
 * Mocked in the third series of Doctor Who when dealing with, Martha asks if he is  . To which the Doctor responds, "you've been watching too much television."
 * Though, it was originally going to be played straight, and, the dialogue was originally going to  ! This line was cut before filming, though, leaving the canonocity of it heavily debated.
 * Played straight in, where
 * Masterfully inverted, gender-swapped, and played without melodrama in The Tenth Kingdom, when via the magic mirror Virginia and her father learn that . Not only is this trope combined with that of the Mysterious Parent (though here there is no revelation about the child), but despite the constant references throughout the miniseries, the scene of The Reveal genuinely took this editor by surprise when he first saw it—and it did for every other person he's ever shown the film to. It's that subtle, but so obvious on a second viewing... rather like The Sixth Sense. What makes it particularly unique is that, rather than the villain making the revelation, it comes from a third party (in this case a magical object), and it is the hero who must then convince their erstwhile parent of the truth, rather than the reverse. The tragedy ensues when
 * Parodied on The Daily Show. Stephen Colbert is asked to report on the cancellation of daytime drama Another World. He goes off on a wild melodramatic tangent, reveals that Colbert is not his real name and accuses Jon Stewart of abandoning his "bastard elevator baby". Subverted within the parody because when Stephen finally calls him "Daddy", Jon spoils it by pointing out that they're the same age.
 * Caleb and Sheriff Buck of American Gothic. Unique in that it is revealed in the pilot of the series, and that while Caleb reacts in disgust and anger at the notion, he never has a Heroic BSOD or otherwise freaks out over the revelation. In fact the more time passes, the less issue he seems to take with it, even welcoming and embracing the relationship by the end of the series. This could be due to being orphaned and having no one else to turn to except an increasingly unstable doctor and a Cool Big Sis cool cousin who is also being drawn into Buck's orbit, but all things considered, probably not.
 * Subverted in Veronica Mars. Paternity tests confirm that Keith Mars is Veronica's father.
 * And then played straight with Logan's adopted sister in an interesting way that somehow managed to avoid the usual cliché of the trope.
 * Done in very a surprising "How the hell did I not see that coming?" way on Dexter when
 * This happens on Green Wing, where Guy discovers that is his mother, making him and  brothers. Unfortunately, he only finds this out after they have sex, leading to a complete meltdown on Guy's part.
 * In Sharpe's Justice, the rabble-rouser Matt Truman is Sharpe's half-brother.
 * In Jonathan Creek, an actress attempts to covertly help the son that she secretly gave up for adoption many years ago by having him cast in the movie she is currently starring in, only to learn that he has developed a bit of an obsession with her, unaware that she is his mother. He's embittered when she rejects him in this sense, understandably a bit Squicked out; unfortunately, she confesses this to her ex-husband who, holding his own grudge, manipulate the son into murdering her.
 * Averted in Without a Trace: Agent Malone is captured and tortured by conwoman who thinks he's an enemy out to get her and her partner who is, naturally, her son. I can't recall all the facts, but in the end the conwoman dies and asks Malone not to tell her son the truth (it probably would've been squicky for him anyway).
 * Parodied innummerable times on Whose Line Is It Anyway?.
 * All My Children loves this trope. Examples: Daisy Cortlandt and Myra Murdock (Nina's "dead" mother and long-lost grandmother), Palmer Cortlandt (Ross Chandler's long-lost father), and Jackson Montgomery (Greenlee Smythe's real father). In the most recent example, the show waved a magic Retcon to make Erica Kane's aborted child appear as Josh Madden, supposedly the son of evil Dr. Madden.
 * Taken to absurdity in A Bit of Fry and Laurie, when they parody Australian soaps:


 * Parodied on Krod Mandoon and The Flaming Sword of Fire. Krod confronts Chancellor Dungalor, who stalls for time by revealing that he's Krod's brother.
 * Played straight in Reaper with revealed to be 's father at the end on season one.
 * Parodied in an episode of The Mighty Boosh, "Journey to the Centre of the Punk": Howlin' Jimmy Jefferson, the Spirit of Jazz, claims to be Howard's father, then uncle, then second cousin twice-removed on his sister's side, in an attempt to keep Howard from killing him. Only the last one works.
 * Played straight in Jekyll,.
 * On Arrested Development,.
 * Played straight in Glee.
 * In the Only Fools and Horses 1987 Christmas special "The Frog's Legacy", Del and Albert hinted that Freddie the Frog, a gentleman safecracker had an affair with Del and Rodney's mum Joannie before Rodney was born.
 * In season 3 of Chuck, where.
 * The very last words said on Kyle XY:
 * One infamous Eastenders moment (2001) is Zoe Slater telling her "sister" Kat: "You can't tell me what to do, you ain't my mother," and getting in response, "YES I AM!"
 * In 3x05 of Merlin, it is revealed that One wouldn't be surprised because this follows the Arthurian legends, but since, one wouldn't be given the impression of anything otherwise.
 * In a 3rd Rock from the Sun two-parter, the Big Giant Head reveals that he is Dick's father. Tommy later likens this to Luke Skywalker finding out about Darth Vader, but Dick brushes him off, saying this is real life.
 * gets this twice.  Then later he and his newfound siblings find out that
 * Which leads to a really bizarre scene in a late season episode where  gathers them all together for a nice family dinner, despite the fact that   Needless to say, it's a tense meal.
 * In the first episode of what is considered possibly the worst TV series made, My Mother the Car, his mother has to admit to David Crabtree that while she's a car, she really is his mother, come back as a 1928 Porter. So, he's sitting in the car and she talks to him. At one point, (3:34 in the video referenced in this example), she says, "David, I am your mother."
 * Lawman: In "The Joker", outlaw Barney Tremain claims to be Johnny McKay's real father. It is left unresolved whether he was telling the truth or not.
 * Bones has this in one episode, where
 * Bones has this in one episode, where

Mythology

 * The Tragedy of Sohrab and Rostam from Persian myths (based somewhat on real events). Rostam's son is raised without meeting his father for years. The young Sohrab decides to become a hero and gathers up a force. Rostam is the Persian equivalent of Hercules and is meanwhile ordered to subdue the marauding enemies. In the final battle, the father and son engage each other in battle, as no one else is a match for either of them. Although Rostam notices similarities between himself and his enemy, it is not until it is too late when he discovers that he has killed his own son.
 * The Irish mythological hero Cuchulainn accidentally kills his son, thinking he is an intruder, only to find out that his son is the victim when it's too late.
 * Older Than Feudalism: Oedipus, in Oedipus the King, finding out that the woman he married is his biological mother, and that guy he killed years ago was his biological father. Oh, and then he had to tell his daughters "I am your brother." Ouch.

Newspaper Comics
"Jason: Wait, you're saying that you were a Star Wars fan long before I was? Dad: Search your feelings, you know this to be true. Jason: NOOOOOOOOOOOOOOOOOOOO!!!!"
 * Parodied brilliantly in FoxTrot. Jason is wearing his Darth Vader helmet to see Episode III, but gets stuck in his helmet. His father helps him get free, commenting that he had that problem with his Vader helmet when he was Jason's age.

"Susanita: Felipe, did you get me something for Mother's Day? Felipe: Why should I get you something for Mother's Day? Susanita: Well, I don't know how to say this... You have to get me something for Mother's Day because... (cue melodrama) I AM YOUR MOTHER! Susanita: (disheveled and bruised) I don't understand, it works in the soaps!"
 * Parodied in Mafalda. Remember, the protagonists are all little children.

Professional Wrestling
"Guerrero: I'M YOUR PAPI!"
 * The 2005 feud between Eddie Guerrero and Rey Mysterio included an angle where Rey's real-life son Dominick was revealed to be the (kayfabe) biological son of Guerrero.

Theater

 * The Marriage of Figaro has an instance of this that's similar to the one from The Italian above: Marcellina is about to force Figaro to marry her in lieu of paying off a debt, when a casual comment he drops about a birthmark reveals that she's his mother. They embrace and make up, leading instantly to a classic Not What It Looks Like scenario...
 * Something similar happens in A Funny Thing Happened on the Way to the Forum, as the Centurion was intending to marry Hero's love interest. Turns out in the ending that not only was the blind man that Pseudolus attempted to distract by having him run across the hills of Rome seven times was his father, but the Centurion and the love interest were actually siblings (they were kidnapped and separated while they were very young, and it was presumably at a time that they simply had no way of remembering due to not knowing this until after he told them). This was more than enough to allow the Centurion to allow Hero to marry the love interest.
 * Happens with the Baker and the Mysterious Man in Into the Woods.
 * Wicked has the Wizard realize that he's Elphaba's father. Elphaba herself never learns the connection—probably all for the better.
 * Urinetown milks the revelation that Penny Pennywise is Hope Cladwell's mother for all that it's worth.
 * In Molière's L Avare (1668) Anselme, the man who Harpagon wants his daughter to marry, ends up being the father of.
 * In the opera Lucrezia Borgia, the title character turns out to be the mother of the protagonist, the young noble Gennaro, by a previous relationship.

Radio
"Stillgoe: Punt and Dennis never told you what happened to your father. Benn: You're not my father! Stillgoe: No, of course I'm not. Whatever gave you that idea?"
 * Spoofed in Mitch Benn's Crimes Against Music when, after a series-long Running Gag about Mitch's rivalry with fellow musical satirist Richard Stillgoe, the final episode features him as a special guest, and a showdown between the two performers.

Stand-up Comedy

 * Comedian Gad Elmaleh parodied this in his stand-up show. His mother, he said, used to tell him that "your father is no Rothschild", i.e. "he's no millionaire, we can't waste money." He then says that he later met Rothschild, only to scream at him: "I know! You're not my father!"
 * There's an old joke about a boy who figures out that he can get adults to give him stuff simply by saying a sly "I know the truth..." and leaving it at that, allowing their minds to jump to "What could he know?" and pay him off without confirming what it is he "knows". Then he tries this on the milkman, who, rather than paying him off, drops down in tears of joy and exclaims "SON!" as he hugs him.

Video Games
""Check your inventory screen, Kid. You know it to be true.""
 * Super Mario Sunshine:
 * After the first Art of Fighting, Yuri Sakazaki revealed to her brother Ryo and his friend Robert Garcia that, the game's final boss, Mr. Karate, was Takauma Sakazaki, Ryo and Yuri's father. Good thing too, Ryo was about to kill him for thinking he was the Big Bad. That honor belonged to Geese Howard who blackmailed Takuma by arranging for Yuri's kidnapping, so he could work for him.
 * Used again in King of Fighters where K's long lost sister is presumably Whip.
 * Throughout the adventure game Bad Mojo, there are hints that  is actually Roger's estranged father. In the game's best ending, if you   at the end of the game, this turns out to be the case.
 * We find out near the end of Tales of Symphonia that . It's hinted at.
 * And in the sequel,
 * In Tales of Eternia, it's more of a "Luke, I am your mother":
 * Does this count? The characters in question both knew. Only the other characters and the audience didn't.
 * In Tales of Destiny,
 * In Chrono Cross, it's revealed (in a huge chunk of exposition that arrives immediately before the unexpected final boss) that
 * Exaggerated in LEGO Star Wars 2 when Darth Vader, Played for Laughs, pulls out a family photo of Padme and Anakin getting married.
 * Parodied twice in Kingdom of Loathing: the Big Bad tells the player she is your mother (quoting, almost word for word, the rest of the exchange from The Empire Strikes Back, right to the Big No)... then insults you for believing her. After you beat her, the Council that sent you to defeat her says "Say, did you know she was your mother?... nah, just kidding" as part of their congratulations message.
 * More than twice, actually. When you kill enough soldiers for both sides in the war in the Mysterious Island quest, you get a choice adventure that lets you choose which boss of which side you get to fight, and the message you get has this. It's even lampshaded that it's been done to death!
 * In the first Fantasy Zone, the commander of the invading forces turns out to be Opa-Opa's father.
 * The Final Fantasy series uses this often:
 * In Final Fantasy VIII, this trope is taken to an extreme, when discovered that  On top of that, numerous hints are dropped later on that the other star of the game, Laguna, is
 * In Final Fantasy IV,.
 * In Final Fantasy IX,.
 * Fairly early in Final Fantasy X, Auron reveals without any explanation for how  beyond "you know it to be true." The explanations don't come until much, much later. Why he expects him to believe this...
 * In Final Fantasy VI, it's implied that is the father of . What's particularly amazing is that it's actually fairly subtle.
 * In Final Fantasy VII, it is revealed near the end of the game that
 * Also, in Final Fantasy II, the Dark Knight in charge of much of Palamecia's military operations turns out to be Leon, the adoptive brother of Firion and Maria.
 * Tragically inverted in Jak III, where
 * Metal Gear Solid did it quite embarrassingly straight—at least to start with. After that it ran with it, taking it to its logical, truly disturbing conclusion.
 * Big Boss is Snake's father—Clone.
 * Liquid is Snake's brother—Twin.
 * Solidus is not only Snake's brother, he's also Raiden's "father"—Foster.
 * While not part of the reveal, The Boss is Big Boss's "mother".
 * Gene, Big Bad of Portable Ops, is Big Boss's "Brother", raised as a successor to The Boss
 * Ocelot is the son of The Boss and The Sorrow (confirmed by the Database)
 * Actually was hinted at in-game, call up EVA sometime before you fight the Pain, she talks about how Ocelot's the son of some legendary soldier who was birthed in the middle of a battlefield.
 * Colonel Campbell is Meryl's father.
 * Grey Fox is also the "brother"/father figure of Naomi. He killed her parents and raised her. One could also say he's a further continuation of the twisted familial relationships. He's practically Gene's "Son". And after Gene's death, he becomes Big Boss's protege to boot!
 * Major Zero
 * Solidus isn't part of the same batch as Solid and Liquid, so presumably they don't have the same surrogate mother.
 * Wooh, that's a lot to sum up. Hideo Kojima and his crew sure like having everyone related with only a very few characters blood related.
 * You know things were getting out of control when Kojima confirmed that The End's pet parrot was the grandparent to Emma Emmerich's pet parrot.
 * In the infamous ending of Monkey Island 2: LeChuck's Revenge, LeChuck is revealed to be Guybrush's brother. Fans are divided over whether this ending is to be considered canonical, or a dream sequence.
 * A particularly egregious use of this trope in Fire Emblem: Radiant Dawn. We learn that Micaiah is and Soren is
 * Given the requirements necessary to unlock the ending that reveals this (an A support with Soren and Ike in Path of Radiance, uploading that info to Radiant Dawn via save files, and getting an A support with Soren again, then beating the game twice to unlock the ending where ), all of which fleshes out the background of these various characters, it makes a distinct sort of sense.
 * And Soren's resemblance to Kurthnaga and Rajaion, even in Path of Radiance.
 * Furthermore, Micaiah's reveal is addressed as early as.
 * Since Micaiah was a Mary Sue, we should have all seen this kind of thing coming.
 * Other FE examples: Yuria is Celice's half-sister, Nergal is the father of Ninian and Nils, and Joshua is Ismaire's son.
 * In Super Robot Wars Alpha and Super Robot Wars Original Generation Levi Tolah, one of the invading aliens is actually Aya Kobayashi's Brainwashed and Crazy
 * Since that wasn't crazy enough, in Super Robot Wars Original Generation 2 it's revealed that
 * I Wanna Be the Guy pulls this out of nowhere with the final boss, "The Guy" that you want to kill for his title being a huge version of the player character. Just to make sure you got it he says, "Yes, I did have sex with your mother." before the final phase of the battle.

"Gnarl: Look, it's our old friend. Gnarl: What! How did you know-- hang on, I recognize that voice now! Don't trust her."
 * No More Heroes tell the story of Travis Touchdown who became the best assassin in the US by a fictive association and that one of the responsible is in fact
 * It's actually much more complicated than that.
 * The Darkshine Knight from Seiken Densetsu 3 has a backstory that is way too similar to Darth Vader's to be a coincidence.
 * God of War:
 * Viewtiful Joe does this quite blatantly when, to the point of downright quoting Darth Vader. The entire game is one big homage to movies, so it fits.
 * They did it again in the sequel where the Big Bad was  and yet again the DS game double trouble where the Big Bad was.
 * Implied by Portal 2, which confirms that Chell is the  daughter of   A Bilingual Bonus supports this, with the lyrics of   song translating to something along the lines of "Goodbye, my sweet child. Stay away from science."
 * In Mother 3, the Masked Man turns out to be
 * There are no coincidences in the Fire Emblem games. From the Sealed Sword/Blazing Blade saga, Nino turns out to be Canas's niece, Dart is Rebecca's long-lost brother Dan, Raven is actually Priscilla's brother Raymond. Then, in Path of Radiance/Radiant Dawn, is really Lehran, the patriarch of the Begnion line of apostles/empresses  . However, Empress Sanaki cannot hear the voice of the goddess because the apostle power is only passed down to the firstborn female of each generation, and unbeknownst to her, she had an older sister. We later find out that this is  Also, Mad King Ashnard's mount is really the Goldoan prince Rajaion, and his mistress, Almedha, is Rajaion's sister. Ena, Rajaion's fiancee, went to Daein to try to save him in Path of Radiance, but her grandfather, Nasir, was serving as a mole in the Crimean party. Oh, and  Did we mention that Calill and Largo's adopted daughter is also a Branded? This is the most convoluted series ever.
 * There is also the Fire Emblem Gaiden game, in which Alm has to fight this one warlord who refuses to attack him. When you kill the warlord, he says with his dying breath "Alm, I am your father!" Alm is a little upset by this. However, The Obi-Wan tells him to not bother wasting tears on the guy, because "He was a madman who would have killed you as an infant had you not been taken away fast enough!"
 * The Disgaea series. Nippon Ichi loves playing with this, and making them major plot points...
 * It happens at least three times in the first game:
 * This is hinted at in game, somewhat more strongly in the anime adaption of the game (even though it lacks the, and confirmed by the World of Disgaea artbook.
 * The game does everything to tell you, short of actually telling you, and the anime preserves this plot point.
 * As if they didn't beat this trope into the ground with the first game, they brought it back in the second game to beat it under the ground.
 * Again, the game does everything to tell you, short of actually telling you.
 * The second point is, once again, confirmed by the World of Disgaea artbook.
 * With the third game, they don't bother even trying to take it seriously anymore...
 * In one scene, . It doesn't work, mostly because.
 * And in Rasbperyl mode, Master Big Star and Salvatore claim to be the Vato Brothers' parents, while two Prinnies claim to be the parents of Gold Knuckle. All of this, needless to say, is both impossible and absolutely ridiculous.

 * In F.E.A.R., the  is Alma's first son.
 * Rival Schools: United by Fate reveals that The Hero Batsu is the son of (literal) Big Bad Raizo. In a surprising twist, Batsu also learns that his classmate Kyosuke and the real Big Bad Hyo are twin brothers and Batsu's cousins (their father Mugen is the older brother of Raizo).

 * In Baten Kaitos, you find out at one point that  However, since you find out even later that , this doesn't mean what you think it means.
 * A popular Team Fortress 2 theory is the idea that the Spy is the Scout's father. In "Meet the Spy," the BLU Spy reveals that the RED Spy has been sleeping with the BLU Scout's mother. A drawing of the Scout's mother is engraved on the barrel of the Spy's unlockable handgun, the Ambassador. And one achievement for the Spy, "Who's Your Daddy," involves headshotting three Scouts with the Ambassador, the gun on which his mother is engraved.
 * Another popular idea is assuming the Pyro is female and the Scout's mother, explaining why the Pyro and Spy are archenemies (she hates him for whatever reason) and is in the thick of battle to watch over her son. A related theory is that the unseen Announcer is the Scout's mother, or that the Pyro and Announcer are somehow the same person.
 * We contacted the Pyro about this, and we recieved this response: "Mwafah hah har rarara."
 * This gets even more confusing given that the BLU Scout depicted in "Meet the Spy" is the RED Spy in disguise!

 * Questionable Content references it in this strip.
 * In Looking for Group, when Richard is in the demonic court on the Plane of Suck, he is asked why he travels with Cale. He responds with a mumbled "He's my mother." This gets a "What?" reaction from everyone in the room, including Richard. Probably just a joke, though. But they said that about the rabbit, too, so...
 * Subverted in the Dan and Mab's Furry Adventures side-comic Abel's Story, in which Abel
 * Darths and Droids: Twice, and neither time is the one you'd expect (yet). "Anakin, I am your stepfather." And later: "No! Wait! Anakin, Ah am your f--. In the latter case, however, he may have been about to say "friend."
 * Order of the Stick parodies the Empire Strikes Back scene in a recent strip, but as a whole this is not an example of this trope. Because Elan's father was introduced one strip before the reveal, it's a case of Luke, You Are My Father.
 * Well, he did show up in one Flashback over 600 episodes before that, here, although he wasn't named then and hasn't been seen since. Still, the "reveal" came as no surprise to someone with a good memory.
 * The Mulberry story "Mul/Kerry/Bush" included a scene where George W. Bush tried to escape Mulberry's experiment by claiming he was her father. Since Mulberry has Invisible Parents, she nearly believed him, until Tiff pointed out that her last name isn't "Bush."

No, seriously.
 * Parodied, once again, in College Saga.

 * Avatar: The Last Airbender: In "The Avatar and the Firelord", it is revealed that  Did we mention that Mark Hamill voices  father? Cue run-in-the-family memes.
 * Such a moment happens in WITCH when Caleb finds out that.
 * Winx Club has Roxy finding out that
 * He-Man and the Masters of the Universe: in the original series episode "Teela's Quest", the titular Hot Amazon finds out that she's the daughter of the Sorceress. Her mommy gave her Easy Amnesia, though, since Teela was NOT supposed to find out. This would've been true in the 2002 remake, but without the amnesia, had the show continued. Oh, we would've also learned that Fisto was Teela's biological father. For some reason, a couple of episodes seemed to hint that it was Duncan a.k.a. Man-At-Arms (who happens to be Fisto's brother and Teela's adoptive father) instead.
 * Some time after the end of the original animated series, the minicomic The Search for Keldor dropped hints that Skeletor is really King Randor's long-lost brother Keldor, making him Adam/He-Man's uncle. In the 2002 remake, Skeletor was originally named Keldor, but there is no indication that he is related to Randor.
 * While never stated in the show, the writers have since revealed that Keldor was intended to be Randor's half-brother. Same father, different mothers.
 * Justice League Unlimited pulls this off twice, using Batman Beyond both times. In the episode "The Once and Future Thing", it's revealed that Warhawk, assumed to be the Legacy Character of Hawkman, is (or will be) in fact . "Epilogue", the Fully-Absorbed Finale of Batman Beyond, reveals that
 * Hades also tries to do this with Wonder Woman, with a twist that he had to resort to a technicality when WW pointed out her origin story doesn't allow her to have a father (she was sculpted of clay and made flesh by the breath of her mother, Hippolyte, instead of born; Hades claimed he was there during the sculpting, but not the life-granting).
 * Code Lyoko: It is revealed just before the Season 2 finale that Franz Hopper, creator of Lyoko, is actually Aelita's father. This also reveals that she is human, and not an A.I. as everyone originally thought.
 * Parodied in Teen Titans. In the first episode of the fourth season, Control Freak enters a Star Wars-esque TV show, kicks the Darth Vader lookalike and approached the Luke lookalike with saying, "I am Count Rol Freakow, the twelfth-level space samurai that trained Baran Rang. And... I am your father!". Followed by the typical "NOOOOOOO!!!!"
 * Also played with when Starfire and Killer Moth each try to convince Silkie/Larva M319 to choose between them. Killer Moth's attempt: "Larva M319, I am your father. Join me and we can... go on a picnic or something." Silkie already knew this.
 * Parodied in Dexter's Laboratory:

 * Parodied in The Venture Brothers, quoted above.
 * Evil Emperor Zurg pulled this during a climactic fight scene with the title character in an episode of Buzz Lightyear of Star Command. Quite possibly to give a Shout-Out to the Toy Story 2 movie (Buzz Lightyear of Star Command is a Show Within a Show that got turned into a show. It gets a little headscratch-ey, but the above mention is canon because of this show, which is the derivative work and... yeah, just yeah.) On the other hand, Zurg was implied to have been fooling around, as he then strikes a stunned Buzz and states "made ya look!".
 * In X-Men: Evolution (and also in the comics) Nightcrawler is lured out to a construction site with a mysterious note that promises that "everything will be explained". A hooded figure comes out of the shadows (actually, since it is early evening, there aren't many shadows to speak of, so they obviously added this in for dramatic effect) and, after making Nightcrawler squirm in confusion and anticipation for about thirty seconds, throws her hood off to reveal Mystique, Magneto's Evil Chancellor of sorts and says, "Kurt, I'm your mother." For bonus points, she does it a second time with Rogue (who was adopted, but still), though since it was in the middle of Rogue having a mental breakdown from all her absorbed personalities fighting in her head, it wasn't nearly as dramatic.
 * The original 90s cartoon also did this with Nightcrawler and Mystique, but with the added twist that Big Bad leader of the Friends of Humanity Grayden Creed, Jr. (who was already exposed in an earlier episode as being Sabertooth's son) was Mystique's son and Nightcrawler's half-brother(Just like in the comics).
 * X-Men scribe Chris Claremont originally intended Mystique to be Nightcrawler's father—she's apparently a really good shapeshifter—but Executive Meddling derailed those plans.
 * Thank God.
 * Parodied in The Fairly OddParents in a "copyright-infringing dream sequence":

"Turbo Thunder: Timmy, I am- Timmy: Whoa whoa wait, you're not going to say you're my father and then cut off my hand, are you? TT: No, I'm going to train you. ...Well, it was said something to that effect, that's all I remember."
 * Later lampshaded in that 3-part movie whose name I can't remember, but it was the one with the Terminator parody and such.

"Guitierrez: Freakazoid, help me! Would you let your father fall? Freakazoid: My father? You're my father?! Guitierrez: (glances confused at camera) O-oh yes. I am your father! Freakazoid: (goes to help him, stops) W-who was my mother? Guitierrez: Uhh... Faye Dunaway? Freakazoid: (crosses arms) No she's not... Guitierrez: Kaye Ballard? Freakazoid: Kaye--nooo. Guitierrez: Would you believe Sandy Duncan?"
 * A brilliant continutynod to the quote starting the Fairy Odd Parents section here.
 * Parodied in Freakazoid!, in the episode "The Wrath of Guitierrez". During the climax of the episode, Guitierrez is knocked off a platform and hangs dangling over an abyss, and cries for Freakazoid to pull him up.

"Leela: They killed my parents (Leela is with two cloaked figures when Fry appears) Fry: Close (pulls down the hoods) Leela:They...are my parents"

"CheapSkate: You can't turn me in, Skate Lad. Skate Lad: Give me one good reason. CheapSkate: Well, um, because, uh... Skate Lad, I am your father. Skate Lad: Huh?! No you're not; my dad works down at the sporting goods store. I look just like him, loser!"
 * Parodied in Teamo Supremo when Skate Lad corners the CheapSkate.

"Darth Vader knock-off: I did not destroy your second cousin. I am your second cousin! Johnny: Nooooooooooooooo!!!"
 * The final episode of The Replacements reveals that Conrad Fleem is Todd and Riley's uncle.
 * Parodied in Phineas and Ferb, in the episode "The Chronicles of Meap". The pair mistake an alien villain (named Mitch) is the eponymous Meap's father, due to miscommunication. Later, after having discovered this, Mitch quite explicitly tells Meap "Just so we're clear on this, I am not your father!"
 * In Chaotic, the card game revealed something more of a "I am also your founder" with Kiru, the greatest Overworld hero (even got a beautiful city named after him)
 * From South Park episode 201: Eric Cartman,
 * Played with in Galaxy Rangers: Wheiner attempts to blackmail Walsh by threatening to reveal that Shane is Walsh's biological son. Shane never discovers this fact.
 * Parodied in Johnny Bravo.


 * A variation was used in the Pale Kids episode of Recess. Lawson hated the Pale Kids because of something that happened to Tiny Sedwick, a kid who had to go to the Pale Kids because he broke his foot while playing Pickle. When telling the leader upfront, the Pale Kids laughed, with Lawson reacting with confusion as to what they think is so funny about his reason, before the leader tells Lawson that he is Tiny Sedwick (or at least was).
