Paper-Thin Disguise/Video Games

"Banjo: I'm Banjo the Stony. Can I come in and play? Officer Unogopaz: Hmm... I don't know. That backpack looks kinda familiar... Kazooie: Are you saying we're a bear and a bird in an elaborate disguise, trying to cheat our way in? Officer Unogopaz: Yep, it's pretty obvious."

- Banjo-Tooie

Examples of in  include:

""You know who this is, right? Yeah, I didn't do any of the design.""
 * Played with in HeartGold/SoulSilver, where you have to infiltrate Team Rocket's activities at the Goldenrod Radio Tower by donning their uniform. Hilariously, the same Mooks who just shoved you away from the door gives you a cursory look, then allows you to pass. Especially funny when you consider that all Rocket Grunts look alike, and generally aren't sporting a ridiculous hat and pigtails, if you're a female player.
 * Made better when your rival comes in, recognizes you immediately, wonders what's up with the disguise, and strips you of it, then to have the grunt finally recognize you.
 * Speaking of which, a variation involving inanimate objects was also used. The transmitter used to cause the Gyarados to evolve at a rapid rate at Lake of Rage (and was implied to be the cause of the Red Gyarados) was disguised as a tree near the shop. And by disguised, I mean rather obviously (the control box was clearly seen, not to mention most of the "tree" was metallic gray).
 * Played straight in every game of the Hitman series, where 47 can get away with some rather ridiculous disguises (Six foot white guy dressed as a Chinese triad member, anyone?). However, this is averted on harder difficulty settings where most "disguises" won't be all that effective, even against Mooks.
 * In Sonic Adventure 2, a hedgehog named Shadow steals a chaos emerald from Station Square, and despite having black fur with red highlights and a different hairstyle, the military takes and charges Sonic for the crime, believing he did it.
 * Later in the game, even Amy who is deeply obsessed and in love with Sonic mistakes Shadow for Sonic.
 * Fans have explained these two as a government cover-up and Amy being retarded, as she also mistook Silver for Sonic in |that one game that never happened.
 * In Paper Mario: The Thousand-Year Door, one of the members on the sailing crew you join up with is obviously Lord Crump, The Dragon to the head of the X-Nauts. No one notices, but in an aside he does ask the person 'behind the TV' not to tell Mario his real identity or else, also lampshading the ridiculousness of the disguise in the process. Since every character in the game is two-dimensional (as in, physically), this is quite literally a Paper-Thin Disguise.
 * Additionally, Mario can "disguise" as Luigi by wearing the L badge. All this does is Palette Swap his clothes to green, but it's still enough for a self-proclaimed Luigi fan to mistake Mario for the real thing.
 * Even worse is that she is so convinced that Mario is actually Luigi that when the real Luigi suddenly shows up the fan accuses him of being an imposter.
 * In Super Paper Mario, Nastasia dresses Luigi in black clothes and provides him with a mask, so his brother won't find out that Mr. L is really Brainwashed and Crazy Luigi. However, he keeps his hat, his mustache, his way of moving, his shoes.... virtually everything about him is shouting: "HEY, I'M-A LUIGI IN-A A BADASS-COSTUME-A!!!"
 * ...And yet Bowser still doesn't recognize him.
 * In Super Mario Sunshine, Shadow Mario commits vandalism on Isle Delfino and the Piantas believe Mario to be the culprit, as despite the fact that Shadow Mario is totally blue with a watery texture he had to be Mario. Then again, there seems to be an in-game justification considering the laughably bad drawing of Mario they painted on the Wanted posters.
 * In Paper Mario, the first boss starts off as a boxy, conspicuously fake disguise of Bowser. The four Koopa Troopas inside converse with each other loudly enough for Mario to overhear while in disguise, which doesn't help much, either.
 * In Hotel Mario, Iggy wears a comically oversized Bowser mask (and nothing else to disguise himself) during his battle.
 * Subverted in Super Robot Wars Alpha 3 and Original Generation 2, in which Elzam V. Branstein dons the identity of Ratsel Feinschmecker (German for "Mysterious Gourmet", a fitting time for an avid chef like Elzam) in order to fight alongside the heroes again. The "disguise" consists of nothing more than a pair of sunglasses and a slightly different style of clothing. The other heroes see right through it (except Arado, who isn't exactly the sharpest knife in the drawer, and Lefina, who is just too trusting when Ratsel tells her he isn't Elzam), but as officially having a former enemy pilot around might raise too many questions amongst the top brass, they play along with only the barest of efforts, often just substituting the name "Ratsel" when referring to Elzam, even if talking about something he did as Elzam.
 * The Elzam/Ratsel disguise is a Shout-Out to Mobile Suit Zeta Gundam, where Char Aznable, The Ace for Zeon, swaps out his full-face mask and helmet for a pair of sunglasses and goes by the name Quattro Bageena (it helps that he also falsified official records). At one point Ratsel even says "I am Ratsel Feinschmecker, no more, no less", pretty much word-for-word what Quattro said when Kamille accused him of being Char.
 * Considering the number of other enemy pilots that have joined the team (for example, Elzam's very own niece, Leona Garstein), the going theory is that he's doing it as a form of penance. Or something. Mostly people just humor him because he pretty much is the best pilot on the planet. And he owns a battleship with a drill on the front.
 * To be fair, he's not really trying to fool the heroes, just keep a low profile.
 * Subverted in Lunar 2: Eternal Blue Complete. One of the five heroes of the game is Leo, a Knight Templar who eventually does a Heel Face Turn. At a point in the game before he joins you permanently, the goddess he serves throws your party in jail. A masked man named Mystere (who looks exactly like Leo-plus-domino-mask and uses the same attacks) frees the party, denies any connection, and chews the scenery a bit. Later, Mystere vanishes and Leo returns. No one's fooled, though they keep up the illusion for Leo's sake. Another character speculates that Mystere is how Leo rebels against the elements of his job as Knight Templar which offend his sense of justice.
 * In Mega Man 6 for the NES, a mysterious contest promoter known as Mr. X appears to be the villain of the piece...unfortunately he bears a staggering resemblance to the regular game Big Bad Dr. Wily, except he has sunglasses, a beard, and a dot on his forehead. Capcom had tried this in the last two games, with 4 having the Russian scientist Dr. Cossack as the villain until it is revealed Dr. Wily was simply blackmailing him with his daughter. 5 claimed Mega Man's brother Proto Man was the villain, but he was simply a robotic impostor called Dark Man built by - you guessed it - Dr. Wily. With this flimsy Mr. X disguise, Capcom were clearly not even trying anymore.
 * Even Inafune himself lampshades it:

"Spy/Road worker: My red sign helps me work on the road. Spy/Assassin: I like to shoot people. Spy/Sewer worker: Feces."
 * On the other hand in Mega Man Battle Network 6
 * Actually,
 * The mysterious ??? guy who manages Proto Man's shop in 10 looks surprisingly similar to Auto with a Met helmet. With his cat sleeping on the counter. Yeah.
 * Team Fortress 2's Spy class has a disguise ability that will make them indistinguishable from an opposite team member... to the opponents. To the spy's friends, he looks like a spy with a cereal-box paper mask on.
 * The original Team Fortress mod as well as Team Fortress Classic averted this trope, with the spy's disguise looking the same for all teams. Teammates had to aim their crosshairs at him to reveal his true identity.
 * The team's bases themselves, disguised as such things as granaries and shipping companies, sometimes qualify. The ones in Double Cross are said to "fool nobody", and 2fort's RED base, meant to be disguised as a farm, has a wooden cow. There are mooing sounds coming from somewhere, presumably a hidden tape recorder.
 * Subverted in Full Throttle. The villain hosts a demolition derby as a ploy to lure out and kill protagonists Ben and Maureen. Ben and Maureen enter the derby in disguises deliberately made to fool everyone except the villain, all as part of a Batman Gambit to fake their own deaths while keeping their true identities hidden from the derby's spectators. The villain even lampshades upon seeing them, "Who do they think they're fooling with those ludicrous disguises?"
 * Psychonauts' Journey to the Center of the Mind of a mad conspiracy theorist has robot-M.I.B. monotonously mimic different everyday roles of Suburbia, ranging from a housewife to an assassin, often using nothing more than one article of the occupation as a disguise. This also works for the main character, though, as merely holding a red sign functions as the perfect disguise of a road worker.
 * Their lines of idle dialogue are just as hilariously paper thin:

"Celes: Why the stupid farce? Edgar: I heard Figaro Castle got stuck after the Floating Continent fell. I wanted to help, but I didn't know where to look. Then I heard that those crooks had escaped from the jail. Celes: You intended to use them... Edgar: Bingo! I had to wait until they led me to their secret cave."
 * Possessing the items causes them to actually perceive you as a house wife/road worker/what have you rather than them taking for granted that the person who is holding the rolling pin is not someone remotely suspicious. Probably still qualifies but...
 * To a further degree, Raz can pass as the head of the mental asylum simply by using an award statue, an oil painting, and a strait jacket. The man working the elevator is nearly blind, but still....
 * The identity of the Cornstalker in Touch Detective 2 1/2 is supposed to be a big secret... but
 * Persona 4 expects even the player to think that all it takes for
 * This is really only a problem in the English version, though. In Japanese,
 * Final Fantasy VI has King Edgar Figaro, a character who, after an event in the game in which the entire party scatters, can be found again in his old hometown, pretending not to recognize you, and claims to be named Gerad -- despite that it's an obvious anagram of his real name, the way he addresses Celes, and his in-game sprite only differing by hair and clothing color.
 * Edgar kept pushing Celes away in order to keep her, and Sabin if he's there too, from blowing his cover - he had a good reason to dress up.

"They are immediately hostile towards the PC, because he/she is American. (And that goes even for Asian-American characters wearing Chinese Army paraphernalia...)"
 * In Final Fantasy VII, Cloud and Co. disguise themselves as Shinra soldiers and sailors in order to get aboard a Shinra vessel. The humans pull off the disguise rather well, but it's hard to believe Red XIII, the anthropomorphic dog/wolf creature, managed to fool anyone...especially considering his tail was poking through the top of his pants and he was struggling to walk on two legs.
 * Bosco in the first season of the Sam & Max games. He even leaves his name tag on.
 * Then again, essentially no one is fooled by it. Certainly not the protagonists.
 * And after Max becomes the President of the U.S., Secret Serv ice-cream vans become ubiquitous.
 * In Okami, a game based partially on using a celestial, godly paintbrush along your quest, the main character, the wolf goddess Amaterasu, must infiltrate a nest of demons whose faces are covered with a paper decorated with a Japanese character. To fit in, a piece of paper is taped to Amaterasu's nose, and the player can draw whatever squiggles they like on it. None of the demons are any the wiser, making this disguise literally paper thin.
 * Lampshaded in that Issun, your Exposition Fairy, says that the mask probably won't work. He seems rather depressed that it actually does.
 * This happens no less than Three times in the sequel; they never catch on until the mask gets lost. Even more ridiculous, two of the three times has you infiltrating the exact same place and passing by the exact same demons, granted, you do re-paint the disguises all three times, but still...
 * Subverted in the Chocobo spinoffs of Final Fantasy. Mog wears an assortment of masks, disguising himself and giving himself a name like "Pop-Up Hero X", but thanks to his predictable use of "kupo", Chocobo eventually sees through him. In Choboco Tales, Shirma: "You're not fooling anyone except yourself."
 * In Barkley Shut Up and Jam Gaiden, Balthios puts on a veil and becomes the Ultimate Hellbane. His speech avatar is identical except darker everywhere but his eyes. His battle sprite doesn't even change, and the battle interface refers to him as "Balthios".
 * This is an unusual example: the disguise works on the PCs, but the first-time player hasn't met Balthios yet and so has no idea who UH is even supposed to be!
 * Subverted in Fire Emblem: The Sacred Stones, in that both the protagonists disguise themselves as mercenaries. Also, their cover is never blown save for one random villager mentioning that one of them "carried himself in a royal manner".
 * However, it is double-subverted when one of your team members, reveals himself as long-lost, self-exiled prince . It's kept very well-concealed due to the fact that a fair amount of people from his country look similar (more so than most of the others), and also to the fact that
 * For another Fire Emblem example, Devdan/Danved in 9 and 10 has a disguise that's beyond paper thin. His constant denial is absolutely the only evidence that the two are not the same.
 * In Blazing Sword, the player's army sneaks into Bern. The three lords don ragged brown cloaks without hoods. This is somewhat effective with Hector and Lyn, but Eliwood never bothers to take off his highly visible crown.
 * A much older example is Sirius, from Mystery of the Emblem. Even though pretty much everybody knows that he is really Camus beneath his Cool Mask, his true identity is never revealed (except if you count his Suspiciously Specific Denial when  as a very thinly-veiled confirmation).
 * In Fire Emblem Cipher, despite how crude a disguise it is, it manages to fool the the game mechanics. Since Camus, Zeke (the name he takes in Fire Emblem Gaiden) and Sirius all have different names they are treated as completely seperate characters, able be deployed at the same time, untable to promote into eachother and unable to be fuel the other's critical/evasion. Strangely the much better disguised has a card that counts as both his real identity and the Black Knight.
 * Tallis in the new Mark of the Assassin DLC adventure for Dragon Age II gets her hands on the MacGuffin by putting an Orlesian guard's helmet on and letting the Duke hand it to her. This doesn't make much sense, due primarily to the fact that she's a female elf and thus a lot shorter than the normal guards, but also because she isn't wearing all that much clothing.
 * In The World Ends With You
 * Lampshaded in Banjo-Tooie, when Banjo turns himself into a Stony in order to enter a kickball stadium (he still retains his backpack, his shorts, and the shape of his face). It seemed like he was foiled when the officer recognises him, but he is let in anyway as the participating players were running short.
 * Metal Gear Solid: "What's that? Huh, it's just a box."
 * Also, Liquid's disguise as Master Miller in MGS1 consisted of little more than putting his hair up, putting on some sunglasses, and changing his accent. He still had his distinctively dramatic way of speaking. It was pretty easy to see that it was Liquid at first glance. This was even more humorous upon the game's original release, as Master Miller had a very dark skin tone (not to mention black hair instead of blond hair) in Metal Gear 2: Solid Snake.
 * Of course it was retroactively subverted in the rerelease of Metal Gear 2: Solid Snake, and especially in Metal Gear Solid Peace Walker, where it turns out that Miller really did look and sound like that.
 * Snake's "disguise" in MGS2 has to count as well. Snake's Iroquois Pliskin disguise involves... wearing different clothes. That's it.
 * To be fair, Raiden's never seen Snake in person, he's grown a beard since Shadow Moses, and he isn't wearing his trademark bandana while in disguise.
 * Metal Gear Solid 3: Snake Eater had something similar: EVA disguised herself as a KGB operative named Tatyana so she could get closer to Volgin and steal the Philosopher's Legacy. Her disguise basically consisted of... her wearing glasses and a slightly different hairstyle. Oh, and also a different outfit. Kojima even lampshades this in the director's commentary.
 * Similarly enough, Snake can easily fool guards when wearing the Scientist and Maintenance disguise (as long as he doesn't wear facepaint as well), despite keeping the bandana among other things, and even if the guards get suspicious, all he has to do to confirm he's a scientist is readjust his glasses. Now, if he encounters other scientists/maintenance crew members (depending on the disguise) face to face, that's a different story.
 * Inverted in the case of Snake meeting Volgin while disguised as Raikov. Despite being disguised so well that Zero claimed that even Raikov's own mother would not tell the difference, Volgin easily saw through the disguise (after pulling a Groin Attack on Snake twice). Hilariously double subverted during the final battle, where you can easily gain a free hit on Volgin if you wear the Raikov mask, without even changing into his officer uniform, and was missing the hat. To further add insult to injury, Volgin is fooled even though you put on the mask in front of him!
 * Subverted in his appearance in the Subspace Emissionary story mode of Super Smash Bros.. Brawl, where Lucario easily saw through Snake's cardboard box trick (literally in this case, as he used his Aura sight to detect him).
 * RuneScape uses this trope quite a few times where sometimes only changing one to three articles completely trick the NPC.
 * In "Eagle's Peak" quest, the player tricks other humans and eagle by disguising him/herself with a fake beak and fake wings.
 * In the "Branches of Darkmeyer" quest, the player fools the entire vampyre society into believing that the player is a vyrelord (one of the highest ranking vampyres), using only some quest-specific robes - despite the fact that vyrewatch and vyrelords have wings and can fly. The player cannot.
 * Also averted, in that even if you get a sex change, different skin color, different hair color and style, and a new basic wardrobe, most significant NPCs will still recognize you and call you by name - unless you're wearing one of the aforementioned disguises.
 * In San Andreas, cops will lose track of you if you go into your house in front of their very eyes, put on a pair of joke glasses (y'know, thick frames, bushy eyebrows and a huge nose) and walk out the front door, waving to them.
 * In Grand Theft Auto Vice City, the cops will lose track of you if you go into your house in front of their very eyes, put on a "clean" version of the same outfit you were wearing when you walked in and walk out the front door, as long as you don't have more than two wanted stars.
 * Not to mention that in every game from GTA3 onward, you can drive almost any vehicle into a Pay-n-Spray in full view of the fuzz and be completely ignored when you drive out in the exact same vehicle. There are a few exceptions (buses, police cars, etc) which the Pay-n-Spray employees will refuse to touch, probably because they only come in the one color scheme.
 * Grand Theft Auto IV averts this trope while maintaining the game mechanic. You can escape the Police if you switch vehicles out of sight, though if they see you through the window, they'll recognize you and continue pursuit. Less realistically, you can still use the Pay-n-Spray to lose the cops, if they don't see you go in.
 * But more realistic in that 3 hours pass, meaning your character waits for the heat to cool down.
 * Subverted in Mother 3, where Lucas and his dog want to get into a nightclub, only to be informed by the bouncers that "No Dogs Allowed". The two slink away and seconds later, Lucas and his dog (now wearing human clothes and walking upright) walk up and try to enter. The guards aren't fooled, and even mention that Lucas was just here with his dog, and now conveniently walks up with a dude who looks like a dog. They only get in due to one of the staff members vouching for them.
 * Also played seriously when you walk in a Pig Mask base with masks for everyone except Lucas... who they mistake for their commander, of all people.
 * In Rayman: Raving Rabbids 2, Rayman's disguise manages to fool a Rabbid general holding a reference picture. Of course, the French titles of the original Raving Rabbids and this game translate as "Rayman vs. the Stupid Rabbits" and "Rayman vs. the Even Stupider Rabbits", respectively.
 * Of course, there was the immortal "It's just a big nosed bush" disguise in Rayman Revolution. Because big nosed bushes regularly spontaneously sprout on the way into your pirate stronghold. Sure.
 * In Assassin's Creed, all Altaïr needs to do to become a monk is to start praying. Guards will completely ignore him, including the multiple swords on his body, dozens of knives, metal gauntlets, assassin sash, etc.
 * However, he does have to be in the middle of a group of real monks to do this. And as most of his weapons are at least moderately concealed, and the rest of his outfit is extremely similar to that of the monks... and it's considered VERY bad form to shove into the middle of monks in the middle of highly religious societies.
 * The game itself appears to indicate that part of Altaïr's ability to blend comes from the assassin equivalent of the Jedi mind trick. On top of that, it's worth mentioning that the individual templar mooks stationed in the various cities and throughout the kingdom can spot you in an instant even if you are blending. The regular mooks don't notice a thing though.
 * Of course, with this all occurring as genetic memory being manifested by the Animus, its quite possible that Altaïr used stealthier methods of hiding, only the Animus is showing what actually happened in simpler terms.
 * In Etna Mode in the 2 remakes of Disgaea: Hour of Darkness, Enta manages to convince many people that Laharl is still alive by attaching a pair of antenna to a Prinnie that resembles Laharl's Expressive Hair. Vyers/Mid-Boss is one of the few people it does not fool.
 * Strong Bad's Homestar costume in Strong Bads Cool Game for Attractive People Episode 1: Homestar Ruiner includes a makeshift head through which his eyes are clearly exposed. No one questions that fact. Nor do they question the fact that Strong Bad is several inches shorter than Homestar and has visible arms.
 * Averted in Dangeresque 3: The Criminal Projective, where Perducci's disguise is pulled off by using another actor.
 * In City of Heroes, Mender Silos, the leader of the Menders of Ouroboros, has the exact same hairstyle as Nemesis. To their credit, between that, the Significant Anagram, and the fact that most players would assume there's a connection between Ouroboros and Nemesis anyway, the developers know they're not fooling anyone.
 * In The Legend of Zelda the Wind Waker, the traveling merchant Beedle apparently runs some sort of black market near one of the islands. His only disguise is a helmet.
 * Similarly, in Majora's Mask, the nighttime black market is run by the same person who runs the regular daytime market... in the same building. His "disguise" is a pair of sunglasses.
 * Also in Majora's Mask, a few of the non-transformative masks (namely Don Gero's Mask, the Captain's Hat, and the Gibdo Mask), will make certain people and/or monsters believe you are someone or something else.
 * Hilarious subversion: If you put on the Captain's Hat in your fight with the undead King Ikana, he is briefly struck speechless at the sight of Captain Keeta...but then his Genre Savvy kicks in and he realizes the somewhat major size difference between Link and Keeta.
 * The Stone Mask, which looks like a weird stone face, apparently makes most people and monsters consider you to be as "inconspicuous as a stone". Interestingly, you can't see the NPC who gives it to you without using the Lens of Truth.
 * Speaking of Zelda, in The Legend of Zelda Ocarina of Time, Sheik was simply a Paper-Thin Disguise (ok, better than most, but it seemed fairly obvious) for Zelda.
 * Not to mention every mask you can wear. Somehow people believe you are a female, a fishman or a large earth man because of it. No one seems to be able to notice you are 1/4 the size of any of them.
 * Link had been asleep for years and Zelda had grown up in that time, so that probably played a part.
 * In The Legend of Zelda: Breath of the Wild, the Monster Masks sold by Kilton the Monster Merchant look barely better than a child's Halloween mask. Some of them don't even fully cover Link's face. Still, they work, letting Link fool whatever monster he's "disguised" as into thinking he's one of them. They don't fool other monsters or NPCs, however.
 * Lampshaded in Lego Star Wars where a disguise is a moustache. Even on the women.
 * Stormtrooper disguises in Lego Star Wars 2. Just the helmet. This looks frankly ludicrous when it's Chewie wearing one, because it sits off kilter like a fez. It still fools everyone.
 * The really ironic part is that in freeform mode, you can play as a fully uniformed Stormtrooper, but all the other Stormtroopers will immediately know that you're not on their side.
 * Also in Lego Indiana Jones. It involves stealing a Nazi hat or a turban.
 * The mustache disguise is particularly amusing in the vehicle levels, where the spaceships wear mustaches...
 * In Arcana Heart, one of the characters, Kamui Tokonomiya, who is a thousand-something years old, and protector of Earth, is spotted by one of the other characters and it is immediately made known who she is. Her response? "But, my disguise was foolproof. I tied my hair back!". Add to the fact that she certainly STANDS OUT for carrying a katana everywhere...
 * Day of the Tentacle: Laverne disguises herself as a tentacle with an outfit of the wrong color that leaves her head, arms and feet visible. None of the tentacles see through it, and a couple of them are attracted to her.
 * Xenosaga Episode III: The creator of T-elos, the more advanced version of KOS-MOS, is named "Roth Mantel". Roth Mantel translates to "Red Mantle". Guess who? . Granted, this is a bit stronger than most (since Roth only has a passing resemblance to his true self), but considering the thematic names of a lot of people in the series, and the fact that T-elos is remarkably similar to a prototype that had no plans that weren't encrypted ten ways from Sunday, Shion should have well picked up on it.
 * Either under this or the Wig, Dress, Accent, Wario Land Shake has a treasure called the 'Perfect Disguise'. Which is pretty much a pair of glasses and a false mustache, although apparently it works:
 * No one will ever know it's you!
 * In Donkey Kong Country, King K. Rool seems to make a habit of this. Subverted in that he fools no one (except, oddly, whoever it was who wrote his trophy description in Super Smash Bros.. Brawl), and there isn't even any real indication that he's trying to fool anyone. Apparently, he just likes dressing up in strange costumes and changing his title.
 * In The Elder Scrolls IV: Oblivion a single mask is the Gray Fox's only disguise, with no change in clothing or voice. Of course, the mask was Blessed with Suck by a godlike being, and in fantasy setting "A Wizard Did It" is justifiedi.
 * In World of Warcraft: Wrath of the Lich King, this trope is subverted. During the Death Knight (An unstoppable, undead killing machine) quest chain, you are required to intercept a messenger. You do this by disguising yourself as... a tree. Made of cardboard. Said messenger promptly remarks "What a strange tree. I must investigate". Shortly before the player leaps out and stabs him to death.
 * Later on in the Burning Steppes quest chain in Cataclysm, you're required to disguise yourself as a member of the Blackrock army using a mask that's the same model as the masks from Hallow's Eve. Most members of the army will fall for it, others will get suspicious requiring you to beat them to death with the cudgel one of the commanders gave you.
 * Averted in Fallout 3, where it is impossible to disguise yourself. Your character is instantly recognizable, even dressed like this. Perhaps the wiki puts it best:


 * Although this is silly. They shoot you because they are a forgotten and zombified invasion force and damn well know who's on their side, as they've been living in a building with them for 200 years. And there is no Chinese power armor in the game that would hide your face appropriately.
 * If you walk up to the Outcast base in the DLC Operation Anchorage expansion wearing Outcast armor, you can fool them...for a few lines of dialog. It is a military organization, after all. On the other hand, if you walk up the Outcast base to trade high tech stuff with them while wearing their armor, you not only don't fool them, they will immediately take your armor without payment. (As they conclude that, at best, you stole it from a dead Outcast soldier, if you didn't kill them yourself.)
 * In Fallout 2 Goris, an intelligent talking Deathclaw companion for the player character would wear a brown robe to cover his appearance when not fighting. Absolutely nobody seems suspicious of the giant lumbering figure completely covered in brown cloth even though he's easily twice the size of any human.
 * All things considered with Goris, it's a post-apocalyptic nightmare and people's lack of suspicion can be chalked up to the fact that everything's just fucked up.
 * Although it is ridiculously easy to fool the guards at the gates of 'The Pitt'', just put on a slave outfit, they don't notice your wrist mounted computer or get suspicious about all your carried equipment.
 * Think about it like this, as far as they can tell you escaped and came back with a bunch of cool stuff. They confiscate your equipment at the gate.
 * "Bellena" from Skies of Arcadia. Apparently, changing one's name and wearing less clothing than usual counts as the perfect disguise.
 * Though to be fair, even if the player has seen before, the party has not.
 * Judas, a mask-wearing swordsman who shows up in Tales of Destiny 2 and is quite blatantly Leon Magnus from the first game. It's such an open secret that it warrants a Mythology Gag in Tales of Symphonia: Dawn of the New World, where Presea tells Emil about her invention the Judas Mask, which "hid your face without actually hiding it, yet mysteriously prevented anyone from realising your true identity."
 * Then there's Nelly Cootalot, who can fool the aristocracy of Meeth into thinking she is Angelo Lightfoot, pilot extraordinaire...by stealing and using a fake moustache.
 * In the Medal of Honor series, someone always eventually sees through your disguise. For example, in Frontline, the guard at the entrance to the manor house says "You're not Friedrich! That uniform is wrong. You're an impostor!" Later, at the train station, you steal an officer's uniform, then the officer finds out and comes after you in his underwear. "Hey! That man stole my pants!"
 * In Soldier of Fortune's first Iraq level, you are provided with a disguise, but you soon run into a guard who asks you for identification (which you don't have), and your cover is blown.
 * In Golden Sun: Dark Dawn, two of the main antagonists show up in an early dungeon. One is a green-haired Blood Knight called Blados. The other is a bishounen guy with long blue hair, whom Kraden seems to know from thirty years ago, at the time of the first two games, in which one of the villains was a bishounen guy with long blue hair. But this can't be the same guy, he's wearing a mask!... that covers less than half his face.
 * Somewhat justified when his identity is finally revealed and everyone is shocked, because . Nobody was looking for him.
 * In WWE Smackdown vs. Raw 2011, at one point in Rey Mysterio Jr's storyline after angering the All-American American Jack Swagger you play as Evan Bourne against newcomer Todo Americano (which means All-American) who other than wearing a mask looks like Swagger, wears gear similar to Swagger, and has all the same mannerisms and moves.
 * Estelle in Tales of Vesperia is a princess, which she thinks is a secret. However, when her cover is "blown", she finds out that everyone in the party knew who she was...except Karol.
 * This trope returns to the Tales series in the Play Station 3 version of Tales of Graces through a series of skits in which Richard takes on a superhero identity named "Masque de Baronia" to do good deeds for his friends. However, his 'costume' consists of little more than a turban and a piece of cloth covering his mouth, worn along with his normal attire. Of course, everyone instantly sees through it except for Asbel and Sophie.
 * In the SNES Shadowrun, two morgue workers become terrified of Jake after he rises from the slab they left him on (thinking he's a zombie), and refuse to have anything to do with him. Jake solves this problem by donning a pair of sunglasses, which stops them recognizing him.
 * Devil May Cry 4 has . The only ones who are not fooled by this are Dante and Sanctus.
 * Played straight in The Sims 3. If a sim who works as a private investigator goes on a stakeout, they will hold up a pair of shrub branches, and hide behind them, usually in plain sight. As seen here.
 * In Ragnarok Online, in order to get to the Rekenber Corporation's laboratory for various quests, you just have to wear a pair of geek glasses and a white mustache to get pass the guard guarding the laboratory, and the guard will allow you to pass even if you have a different hairstyle, clothing or even as a female.
 * The 1994 PC game Eagle Eye Mysteries in London has a mystery called "Case of Blood's Bold Bauble," where the protagonists have to get information from an obstructive hotel desk clerk. Your partner borrows another character's glasses and puts them on you, then pretends that you're the star of a new TV show and he/she is your agent. The kicker: the glasses is the only thing your (unseen by you) character's avatar wears in the way of a disguise, your partner doesn't even attempt to disguise him/herself, both of you are children (which means your partner shouldn't be old enough to be a TV actor's agent), the clerk will have presumably met you before (if you're playing the mysteries in the order they're presented), and the clerk still falls for it.
 * Lee Chaolan from Tekken enters the King of Iron Fist Tournament 4 under the disguise of Violet - which consists of dyeing his hair purple and wearing sunglasses. One wonders who he was trying to fool.
 * The Adventures of Robin Hood: Putting on a monk's robe fools guards every time - even when they see you doing it.
 * In the second Sly Cooper game, The Murray disguises himself as an anthropomorphic moose by wearing a stuffed moose head over his own. To be fair, these guys aren't exactly the brightest or most perceptive.
 * Occurs twice in Medi Evil 2: In the Whitechapel level, Dan needs to find a suit and fake beard so he can gain access to a nightclub, and in the second sewer level, he regains the trust of the Mullock clan by wearing the same mask as the clan shaman (despite being at least twice as tall as him).
 * The SNK Gals Fighters Fighting Game has "Miss X", who is essentially the Badass Iori Yagami in a sailor uniform and a bandit's mask. Predictably, no one in the rest of the all-female cast falls for it, and all of them point it out immediately. Also falls under Creepy Crossdresser and Rule 63.
 * Recettear: An Item Shop's Tale features Recette and Tear utilizing a wooden-plank structure roughly crafted to be a tree prop, and labeled "totally a tree".
 * The disguise used by Freddy Pharkas: Frontier Pharmacist in the last act consists of a change of clothes, a neckerchief (which is actually worn around the neck), and a silver ear. Nobody realizes that the man with the silver ear is actually the one-eared pharmacist, up until the Big Bad captures him and removes the fake ear.
 * Despite having long green hair, horns, not altering his voice, and a tendency to wear the same blue clothing, Arle couldn't identify her long-term antagonist Satan in Puyo Puyo TSU's Alternate Ending, all because he was wearing a gold mask that only covered his eyes.
 * Monster Girl Quest Paradox has Alicetroemeria, actually Alice VIII disguised as a human. Said disguise consists solely of wearing a different kind of dress - her face is completely uncovered. The party immediately figures out her identity upon meeting her, yet Heinrich (who's on a journey to defeat Alice VIII) is comically unable to realize this.
 * In Shantae and the Seven Sirens, Rottytops disguises herself as a half-genie, calling herself "Fillin the Blank". Even Shantae (who is often rather ditzy is suspicious, and anyone familiar with the franchise likely recognizes her quickly.
