[[quoteright:348:[[Franchise/{{Superman}} http://static.tvtropes.org/pmwiki/pub/images/Borgonia_7914.jpg]]]]

A [[{{Superhero}} Superhero]]-specific version of the IdenticalStranger (often, but not always, the CriminalDoppelganger): a not-necessarily-identical stranger wearing an identical costume.

Often an EvilTwin, trying to usurp the hero, infiltrate the Justice League, trade on the hero's reputation for personal gain, or convince people that the hero has gone bad.

Occasionally, and only in comics at the Idealistic end of the [[SlidingScaleOfIdealismVersusCynicism Scale]], the hero will travel to some out-of-the-way spot and discover that somebody there has been inspired by tales of the hero, and has adopted an identical costume in tribute. An EmergencyImpersonation plot may or may not result.

Either way, the key point is that wearing an identical costume is sufficient to turn somebody into an IdenticalStranger, regardless of how different they look from the hero out of costume.

The other character's costume will be identical, or at least close enough to appear so when drawn at the comic-book level of detail. It may even be good enough to fool people who know the hero well. (The inspired-by hero's tribute costume will often have some slight difference that will let readers tell the two apart, but it's always deliberate personalisation, never an error resulting from the fact that they designed it based on rumours and have never seen the original for themselves.)

A source of much FridgeLogic involving most costumed characters as to why this doesn't happen to them more often.

Sometimes, if the hero's powers come from a magical [[MineralMacGuffin crystal]], some sort of special [[ClothesMakeTheSuperman uniform]], a suit of PoweredArmor, or whatever. In that case, this trope may involve someone other than the main hero (typically one of the hero's close friends) using the equipment in their place to "pinch hit" for an otherwise unavailable protagonist.

If the copycat's costume isn't very much like the real thing, but people mistake it for the real thing anyway, it's a case of EasyImpersonation (and hopefully it's being played for laughs).

Not to be confused with IdentityImpersonator, where the hero has one of his friends wear an identical outfit so that the hero can appear to be in two places at once (usually to help protect his SecretIdentity).

Similar plots sometimes occur with non-costumed heroes, usually as variations of "conman trading on reputation of hero the mark has never met" -- see LegendaryImpostor.

!!Examples:

[[foldercontrol]]

[[folder:Anime and Manga]]
* After the TimeSkip in ''Manga/OnePiece'', a group of pirates [[PaperThinDisguise impersonate]] the Strawhat Pirates. They even managed to fool some of the Strawhats themselves. In the end, they either got arrested or met a sticky end, since they were nowhere near the calibre of the Strawhats and the kind of attention they got.
* In ''Manga/BlackCat'', a incredibly fat guy runs around impersonating the eponymous bounty hunter.
* In''Webcomic/TowerOfGod'', just as Viole's infamy is starting to spread, a brutish man decides to impersonate him for some easy robberies. He then has the bad luck of picking out Viole's long time companion Hwa Ryun as a victim.
* In TheNineties ''Anime/SailorMoon'',
** In the first season, Zoisite went around town [[CreepyCrossdresser dressed as a blue version of the title character]], setting up disasters to "save" people from immediately after. "She" is then "captured" by Kunzite, leaving the real Sailor Senshi to come to the rescue and promptly get caught themselves. Especially amusing as the only major giveaway should be Zoi being about a foot taller than the original... and you know... [[ShesAManInJapan Male]].
** ''Sailor Moon S'' had a moment like this. Kaolinite had captured Usagi and even pegged her as Sailor Moon. When the Sailor Senshi appear, she's shocked to see Sailor Moon there, blowing her theory to hell and back. What's so funny is that it was actually Minako using the [[ChekhovsGun Disguise Pen]] and even then, she flubbed Usagi's trademark hairstyle!
* ''Anime/FutariWaPrettyCure'' had an episode where a pair of Honoka and Nagisa's classmates dressed up as Cure White and Cure Black. Since almost nobody knew the real Pretty Cure even existed, the effects of this were rather limited, with no cases of mistaken identity at all. Honoka and Nagisa worried that the villains might get confused and attack the impostors, but the villain of the episode wasn't fooled... and proceeded to attack and mind-control the impostors ''anyway'', for the novelty of being able to set up a Pretty Cure vs. Pretty Cure fight.
* Eclair and Lumiere's looks and positions are usurped by [[spoiler:Dvergr and Arv]] in the final arc of ''Anime/KiddyGrade''.
* Towards the end of ''Anime/MagicalGirlLyricalNanohaAs'', the two MalevolentMaskedMen usurp Nanoha and Fate's appearances [[spoiler:[[BreakTheCutie to spectacularly execute the Wolkenritter in front of Hayate's eyes]]]].
* An episode of ''Anime/BattleOfThePlanets'' involved Mark impersonating Zoltar by wearing a costume that actually didn't look much like Zoltar's.
* ''Manga/YuYuHakusho'' had a brief sequence right after [[TheHero The Heroes]] first worked as a team. Yusuke and Kuwabara are both almost too injured to walk, and two guys have started dishonorably jumping random toughs and pounding them, then dropping Yusuke and Kuwabara's names, and turning the whole area against them. Odd one, since they weren't trying to cash in on their reputation (as punks) but to ruin their reputations as honorable punks in order to irritate them and get them to walk into a trap while injured, so they could beat them and cash in on their new reputation as demon-slayers as the persons who beat aforesaid. Can't help feeling it was needlessly elaborate. A later kidnapping scheme relied on 'hey, you, Urameshi,' as bait and worked much better. The guys turned out to have a very passing resemblance to our heroes, but be really remarkably ugly, something Kuwabara takes exception to.
* Kami- Sama from ''Manga/{{Saiyuki}}'' has an interesting case where, yes, he is impersonating a Sanzo priest... but he was also a disciple to one and supposedly inherited the title when his master got bored with it. This trope doesn't kick in till he takes the one thing his master didn't bequeath him (which happens to be the most important) the sutra, from Sanzo. He also tries to get Sanzo to "give" him his followers... yeah the man is insane. No one really falls for it besides him, but it still counts.
* While not so much a "costume" copycat, in ''Manga/FistOfTheNorthStar'', Kenshiro is often-times described as "the man with seven scars". Needless to say, he gets a little puzzled when, after going around the [[AfterTheEnd Post Apocalyptic]] wasteland doing good and taking out small-level warlords, innocent people start freaking the hell out and running away from him. It turns out there's ANOTHER "man with seven scars", the mark of having survived a normally fatal Hokuto Seiken technique, only this guy's a rampaging maniac. When they meet, those scars are the ONLY thing that's similar, as the imposter is about a foot taller, twice as heavily muscled, and wears a mask halfway between a knight's helmet and a boiler grate. [[spoiler:Turns out that it's Jagi, Kenshiro's adopted brother, who lost out on the chance to be the one true successor of Hokuto Seiken, but the kind-hearted Kenshiro refused to kill.]] He gave ''himself'' the scars and was being such a madman simply to ruin Kenshiro's reputation and lure him into a fight.
[[/folder]]

[[folder:Comic Books]]
* An early issue of ''JusticeLeagueOfAmerica'' (#5, 1961) had the League infiltrated by an impostor wearing [[spoiler:Franchise/GreenLantern]]'s outfit and using gadgets to imitate his powers.
* ''Franchise/{{Superman}}'' #169 (1964) featured a story in which a criminal (who, thanks to MagicPlasticSurgery, actually has Superman's face as well) dressing as Superman to gain access to a top secret prototype.
* Jason Todd, the second Robin, after coming BackFromTheDead [[FaceHeelTurn as a villain]], adopted the identity of the hero {{Nightwing}} (who had been the first Robin), much to the real Nightwing's annoyance.
* Subverted once when Dick Grayson/Nightwing ran into a rather psychotic vigilante who wore a domino mask and a hockey jersey with the name Nite-wing on it. There was little chance of mixing the two up.
** More recently, Damian (Bruce's son with Talia Al Ghul) showed up at Wayne Manor, wearing an approximation of the Robin costume, although there were notable differences that were easy to spot, and he wasn't really trying to impersonate current Robin, Tim Drake, so much as make the point that he felt that he should be Robin instead.
** Jason Todd also impersonated the Red Hood, the former identity of the Joker -- the man who killed him.
** And in a later ''ComicBook/{{Robin|Series}}'' plot arc, an old Robin villain was running around dressed as Red Robin - an identity Jason had for about five minutes. Apparently someone pinched his shtick.
*** Which makes it a meta-CostumeCopycat, as Red Robin was Dick Grayson's superhero identity in ''ComicBook/KingdomCome''. Jason also ran around for a while as a GunsAkimbo-wielding Batman. He might as well be called "Copycat Man."
*** And when "Battle for the Cowl" was over, and Dick needed to take Damian as the new Robin (he was just gonna go out and try to fight crime alone anyway), Tim temporarily retired from being Robin. With the General (the last guy to wear the Red Robin costume) in jail, Tim became the new Red Robin (using it as a crux, he didn't want to step on Dick and Damian's shoes and, like Jason, couldn't accept that Bruce was dead and was looking for him).
* Like the previous examples above, a number of people had dressed up as Batman at one time or another. However, because of his mythological nature of being mysterious, it's easy for someone to think that another version of Batman is actually him and it would take a very skilled detective (or at least someone in-the-know) to realize that Batman isn't the real one.
** Gordon knew right away though. How? He turned around [[ComicBook/{{Knightfall}} one time]] and ''[[StealthHiBye Batman was still there.]]'' It was [[Comicbook/{{Azrael}} Jean-Paul Valley]] filling in.
* This is the Chameleon's entire shtick in the ''Comicbook/SpiderMan'' comics.
** For some reason Spidey's especially vulnerable to this. Mysterio has tried it too. You'd think it'd be easier to pick on a BadAssNormal, but [[CutLexLuthorACheck no, they always want to work out how to imitate the superpowers]]. Hell, in UltimateMarvel, some random guy manages to pull this off.
*** According to Marvel, the random guy in the Ultimate Universe was supposed to be that universe's version of Chameleon.
*** It's because he's one of the few heroes around whose costume covers him head to toe and he's not as large or built as most male superheroes tend to be. [[HeroWithBadPublicity Also, he gets enough bad press that plenty of people already think he's a bad guy.]]
* In ''Comicbook/{{Daredevil}}'', while the real Daredevil was imprisoned, an impostor ran around Hell's Kitchen dressed in his suit, and was eventually revealed to be [[spoiler:[[ComicBook/ImmortalIronFist Iron Fist]]]]. In the past, Spider-Man has also masqueraded as Daredevil [[IdentityImpersonator when Matt Murdock and Daredevil needed to be in the same place at the same time]].
** There was also a storyline where the assassin Bullseye pretended to be Daredevil (unsurprisingly, this was bad for DD's public image) while the real Daredevil was missing due to amnesia.
*** In that same story Daredevil also impersonated Bullseye to fight him.
*** Bullseye later ended up running around as Hawkeye.
** Not to mention the maniac hired to impersonate Daredevil in the ''[[Comicbook/DaredevilBornAgain Born Again]]'' storyline. Matt ends up [[Awesome/MarvelComics kicking his ass and stealing his costume before going to defeat Nuke]].
* Franchise/SpiderMan and Comicbook/{{Daredevil}} have been known to dress as each other to protect their secret identities. In one issue, Peter did it because he didn't have a spare costume available and wanted to borrow one of Matt's. Peter may have a special suit just for him, or Daredevil's eye pieces are removable so he can see.
* ''Franchise/{{Batman}}'' #655 (2006) opens with Batman apparently at the mercy of the Joker. Then Batman pulls out a gun. And then the ''real'' Batman shows up...
* It has happened to supervillains too. For instance, Comicbook/{{Catwoman}} has been wrongly implicated for crimes Catman committed.
* In the ''ComicStrip/SpiderMan'' comic strip, there was this random guy who started going around in a Spider-Man suit with the mask off. Unusually, when the real Spider-Man finally appeared with him in public, he made up a story to cover for the impostor.
** The Spider-Man Annual had a story with another example, a conman who masqueraded as Spider-Man and "revealed" his secret identity, then showed off various gadgets that duplicated Spidey's powers to show that he wasn't a mutant, just a [[CrimefightingWithCash crimefighter with cash]]. And he got way better PR than Spidey ever did. Said impostor also introduced the [[CoolCar Spider-Van]], which is SoBadItsGood.
** ''Comicbook/UltimateSpiderMan'' did it again, but DarkerAndEdgier. Some random immigrant wore a Spider-Man suit and started robbing banks with a gun. Needless to say, this was not good for Spidey's reputation. As expected, he gets beaten up by the angsty superhero.
*** But not before the real Spider-Man gets shot by the police when he attempts to stop the impersonator during a bank robbery. OW.
*** As noted above according to Marvel's website, the "Some random immigrant" is the Ultimate Universe version of the Chameleon.
** And yet again, possibly another annual. Peter goes to a little mom-and-pop store in need of workers and runs into someone in his costume. Immediately after running through a checklist ([[GenreSavvy Clone? Robot?]] ''Impostor.'') and finding that this 'Spider-Man' once helped with a robbery and gets free food every time he shows up, Peter follows the guy, finding that he is a teenager who sleeps in an alley. Apparently this is his only reliable food source. After talking with Aunt May, Peter decides not to take offense, saving the kid from a gang and being told afterwards that the kid had stolen groceries from the store, then found a Spider-Man costume, felt bad, and returned them as Spider-Man. He'd like to make up for it. The next day Peter goes back to the store and is told by the woman who runs it that there was some excitement last night, when Spider-Man showed up with a nice new worker.
* While not a true copycat, the CloudCuckooLander {{Deadpool}}'s costume is very similar to Spider-Man's, as is his sense of humor and [[YouFightLikeACow mastery of insult fighting]]. They met once in a comic and [[LampshadeHanging hung a lampshade]] on it.
** Deadpool was originally based on Deathstroke of DC comics, right down to his real name --Deadpool is Wade Wilson, while Deathstroke is Slade Wilson. They actually appeared in a crossover together and noted their similarities.
** Also lampshaded in an issue of ''Deadpool'' which reveals how Deadpool got his costume: he found it in a costume shop, with a note saying, "Thanks but no thanks. -Spider-Man".
* During the ''[[Comicbook/TheDeathOfSuperman Reign of the Supermen]]'' storyline, Hank Henshaw posed as a cyborg Franchise/{{Superman}}, wearing an identical costume with cybernetic implants in areas where Superman had been wounded during his battle with Doomsday. Henshaw, claiming to be Superman returned from the grave, intended to convert Earth into a Warworld and tarnish Superman's name throughout the universe.
** Superman tends to have this happen a fair bit. He even lampshades it in Comicbook/SupermanBatman #2:
--> '''Superman''': I'm getting tired of seeing my face on my enemies.
* In ''ComicBook/FiftyTwo'', everyone thought that Supernova was Franchise/{{Superman}} in disguise. [[spoiler:Actually, it was ComicBook/BoosterGold from the future all along.]]
** The original, Silver Age Supernova ''was'' Superman in disguise.
* A ''part'' of the DarkAvengers team was made up of supervillains given the costumes of heroes under the orders of NormanOsborn, with the government's backing.
** Then Osborn [[VillainWithGoodPublicity took over S.H.I.E.L.D.]], renaming it H.A.M.M.E.R, and led a team of Avengers consisting of himself, a bunch of villains in disguise, one [[FaceHeelTurn hero gone bad]] and whatever Comicbook/{{Ares}} is.
** The ''actual'' {{Thunderbolts}}' very first mission under H.A.M.M.E.R. involved the Headsman impersonating the Green Goblin to clear Osborn's name. [[spoiler:As it turns out, the plan originally called for an "unforeseen accident" that would lead to the Headsman's death. Osborn didn't count on the Ghost's interference.]]
*** What's more, that team was led by the second Comicbook/BlackWidow, secretly [[spoiler:the original Black Widow wearing a wig.]]
** Osborn tried the DarkAvengers idea a second time, following his disgrace and H.A.M.M.E.R's collapse, this time with the backing of a coalition of supervillain groups. When that fell through, the Dark Avengers were taken into custody, and some joined the Thunderbolts (now a work program for supervillains).
* This trope was used to retcon away the severe VillainDecay of supervillain Prometheus, who had gone from a veritable force of nature capable of putting nearly the entire JusticeLeagueOfAmerica on the ropes single-handed, to being a {{Mook|s}} for various Franchise/{{Batman}} villains. It was eventually revealed that the Mook version had been merely an impostor Prometheus using his costume and weapons, while the real Prometheus was trapped in a telepathically-induced catatonic state. After escaping and killing his imposter, Prometheus has returned to his rightful place on the power scale, appearing as the BigBad in a recent miniseries. [[spoiler:He died at the end of it, making the whole impostor reveal a ShaggyDogStory.]]
* This applied to Comicbook/IronMan when Tony Stark had become a drunken wreck thanks to [[TheChessmaster Obadiah]] [[ManipulativeBastard Stane]]. With Tony in no condition to pilot the Iron Man armor, his buddy [[Comicbook/WarMachine Jim Rhodes]] took over as Iron Man until Stark got back on his feet.
* The 1990s Creator/MarvelComics hero ''{{Darkhawk}}'' gained his powers from a special amulet that allowed him to summon a suit of special PoweredArmor to help him fight crime. When protagonist Chris Powell needed time to get his head together after a very unpleasant trauma, his [[HeelFaceTurn former enemy Portal]] briefly took Chris's amulet and filled in for him as Darkhawk, taking on an AxCrazy superhuman [[MadArtist snuff artist]] named Shaper.
* ''Comicbook/ArchieComicsSonicTheHedgehog'' had a special in which Sonic and Knuckles [[LetsYouAndHimFight got into one of their usual fistfights]], at one point both taking on their {{Super Mode}}s. When Knuckles became Hyper Knuckles, Super Sonic called him an impostor and a copycat.
** At one point, both Anti-Sonic and Anti-Antoine decided to mimic their good counterparts. Anti-Ant killed the real one's father, nearly killed King Max Acorn and nearly forced Sally to marry. Anti-Sonic... just flirted with every girl in Knothole. Note that, since their transformations into Scourge and Patch, this is kinda impossible now.
* Happened in the reboot ''Comicbook/{{Legion of Super-Heroes}}'' where a planet was being robbed by "Legionnaires". Which was actually a set of dummies dressed as Legionnaires in a remote-controlled ship....
* TheMightyThor[[Comicbook/TheIncredibleHercules cules]]!
* The Phantom Blot, a MickeyMouse villain, has been subject to this a ''lot'' thanks to his easy-to-mimic costume. [[NotMeThisTime Results]] [[EnemyMine vary]].
* R. Crumb's Mr. Natural, set upon by hoards of adoring hippies, runs and ducks into a second-hand store. He emerges disguised in a beret, sunglassses, a Hawaiian shirt, Bermuda shorts, and a transistor radio, and encounters an exact double. He's also a guru, who accuses Mr. Natural of copying him. Moments later, four or five ''other'' identical guys show up.
* The Reverse Flash in ''Comicbook/TheFlash'' comics. The only difference is that the suit colors are usually different.
* In a ''[[ComicBook/TheSmurfs Smurfs]]'' one-page comic book gag, Papa Smurf hosts a costume party for his little Smurfs to come in their favorite costume. As it turned out, all his little Smurfs came to the party dressed as Papa Smurf, while Papa Smurf came as an ordinary Smurf.

Tribute-hero examples:
* ''Franchise/{{Batman}}'' #86 (1954) featured a story in which Bruce (Batman) Wayne and Dick (Robin) Grayson, on a road trip across the US, discover an Indian reservation protected by Chief Man-of-the-Bats and Little Raven. Not only were these heroes' costumes exactly like those of Batman and Robin except for the addition of feather headdresses, the physical resemblance was so close (despite Chief Man-of-the-Bats and Little Raven being, you know, Indians) that Batman and Robin were able to [[EmergencyImpersonation stand in for them]] when they were injured.
** The two reappeared in a recent arc (''Batman'' #667-669, 2007) dedicated to the ''many'' tribute heroes Batman and Robin had met over the world: Knight and Squire (England), the Legionnaire (Italy), etc.
* A 1980 issue of ''Fantomen'', "Flame", featured a woman inspired to fight injustice by tales of ComicStrip/ThePhantom. She adopted a costume that somehow managed to look just like the Phantom's (apart from the necessary concessions to body shape), despite her never having seen the Phantom herself nor met anybody who had.
* ''Comicbook/ActionComics'' #233 (1957, pictured above) featured a country where everyone was required by law to wear a Superman costume.
* {{Steel}} wore a costume in tribute to Superman after the latter's death. However, he was the only Superman-replacement who didn't claim to be the real thing, and his costume didn't look that similar, other than the symbol and the cape.
** In ''ComicBook/KingdomCome'', Steel eventually switched his focus to Batman, using a Bat-Symbol and an axe instead of an 'S' shield and a hammer.
** ComicBook/{{Superboy}} (Kon-El, Conner) also did not claim to be the real thing. Rather, he admitted and was even proud of being a clone--he just wanted to be called Super''man'' and not Super''boy''.
* Following the return of Comicbook/CaptainAmerica in the 1960s, his appearances through the mid-'50s were {{RetCon}}ned into tribute heroes--the Spirit of '76, the Patriot, and a nameless history professor who went so far as to re-invent the supersoldier formula and get plastic surgery to look like Steve Rogers. Eventually this last fellow [[WithGreatPowerComesGreatInsanity lost his mind due to an unrecognized side-effect]] and slipped into the other version of the trope.
** [[{{Hawkeye}} Clint Barton]] also dressed up as Captain America for a bit after his real death, at Tony Stark's urging. He was shouted out of the idea by his own namesake.
* Spider-Man once met an imitator from The Netherlands (in a comic actually produced there.)
* In ''Webcomic/LoveAndCapes'', Crusader finds out someone was doing this to him. Turns out, it was fellow hero Windstar - the latter was at a Halloween party ''as'' Crusader when someone arrived to take hostages at the party. Windstar used his powers to fake being Crusader to stop them - Crusader noted how dangerous this was, as one of the powers that he had that Windstar lacked was being NighInvulnerable.
[[/folder]]

[[folder:Film]]
* A variation: In ''WesternAnimation/BatmanMaskOfThePhantasm'', TheMovie of ''WesternAnimation/BatmanTheAnimatedSeries'', Batman is blamed for the actions of a new vigilante who also wears a costume with a black cape and makes a point of attacking from the shadows and being seen only in glimpses; in this case, the confusion is not deliberate, but results from the new vigilante making similar style choices.
* ''The Assignment'' (1997). A US naval officer has an uncanny resemblance to Carlos the Jackal, and so is used in a plot by the CIA and Mossad to kill the notorious terrorist by framing him as a CIA informant.
* {{Deconstructed|Trope}} in ''Film/TheDarkKnight'', featuring vigilantes posing as the Batman trying to take down drug deals while brandishing shotguns. At least one of them ended up dead.
[[/folder]]

[[folder:Literature]]
* The children's book ''Superweasel'' had a boy enviro-vigilante, with his evil double committing pure vandalism.
[[/folder]]

[[folder:Live-Action TV]]
* ''Series/{{Angel}}'': Cordelia giving The Groosalugg an L.A.-style makeover, right down to the...spiky hair... Hey, wait a minute...!
--> '''Angel:''' He's wearing ''my'' clothes!
* ''Series/TheAdventuresOfSuperboy'' TV series had an episode, "The Beast and Beauty", with a criminal dressing as Superboy and trading on Superboy's reputation to get access to stuff he could steal. This impostor didn't look anything like Superboy (apart from the costume), and relied on the fact that more people knew of Superboy than really knew what he looked like.
** Another episode had a man who actually did look like Superboy impersonate him. However, he was more of a small time con man than an actual villain and used the scheme to make some quick cash by charging for autographs and pictures.
* One episode of ''Series/TheAdventuresOfSuperman'' had gangsters pay for a boxer to get plastic surgery in order to impersonate the Man of Steel, giving George Reeves a chance to sport a Brooklyn accent.
* Normally, protagonist Sam Collins became bonded with the Servo program in ''Series/SuperhumanSamuraiSyberSquad''. On one occasion when Sam wasn't available, [[TeenGenius Sydney]] convinced Sam's best friend [[BoisterousBruiser Tanker]] to become Servo in Sam's place. Although rather reluctant at first, Tanker proved to actually be pretty good at the job.
* An ''Series/AllThat'' sketch had citizens confused as both Kenan Thompson and Amanda Bynes were wearing a Superdude outfit. And for those not in on the joke: Kenan is a fat black guy; Amanda is a thin white girl.
* The ''Series/QueenOfSwords'' episode "The Counterfeit Queen".
* In the Spanish TV series ''Series/AguilaRoja'', the Ninja-like hero is impersonated as part of trap to capture and kill him. The only reason the plan failed was because [[spoiler: the impostor (a woman) turned out to have been a fellow student at the same Dojo]].
* ''Series/{{Justified}}'': In "The I of the Storm", Dewey Crowe poses as Raylan, including wearing a trademark hat, when ripping off a pair of drug dealers.
[[/folder]]

[[folder:Pinball]]
* Creator/{{Gottlieb}}'s ''Pinball/{{Mayfair}}'', based on ''Theatre/MyFairLady'', shows Eliza and the flower girl walking down the street in identical poses and wearing identical ornate dresses.
[[/folder]]

[[folder:Pro Wrestling]]
* Wrestling example: When the [[Wrestling/NewWorldOrder nWo]] first formed, they started claiming they'd turned Wrestling/{{Sting}} to their side, which Sting vehemently denied... but then somebody in Sting's tights and facepaint started attacking the WCW guys. Sting went to Wrestling/LexLuger, supposedly his best friend in the whole world, and pleaded his case... and not even Lex Luger believed him (keep in mind, the fake Sting was ''not'' exactly identical, just had a similar build and wore the same hairstyle, facepaint, and tights). The whole thing led to a [[GimmickMatches War Games]] match, in which the WCW team was supposedly a man down, as "Sting" would be on the nWo team... but who should come out as WCW's fourth man but the real Sting! He pulled a LookWhatICanDoNow, then ''walked out of the cage'', angry because the WCW wrestlers were so distrustful that they'd actually believe the nWo's little con game.
* That wasn't even the first time someone did that to Sting. During the [[Wrestling/SidEudy Sid Vicious]] vs. Sting match at ''Halloween Havoc'' 1990, Sid and Sting brawled to the backstage area where the cameras could not see the action. Sting and Sid would reappear, with Sting looking like he suddenly gained 40 lbs. Sid would then pin "Sting" to win the World title. As Sid was being announced the victor, the real Sting appeared with a rope hanging from his wrist. As the announcers figured out that Sid's Four Horsemen stablemate Wrestling/BarryWindham was the impostor, Sting would hit the Stinger Splash on Sid to retain the title for real.
* Also, during the early 1990s, Wrestling/TheUndertaker was defeated by Yokozuna in a casket match after copious outside interference by nearly every heel on the roster. A few months later, Wrestling/TedDiBiase brought "the Undertaker" back; in the end this turned out to be a look-alike. Wrestling/PaulBearer (the Undertaker's manager), claimed that Taker would rise again at a PPV to defeat the impostor. So [[MirrorMatch Undertaker and Undertaker]] fought, though it was more like Undertaker versus a Dude dressed like the Undertaker who was shorter and less muscular.
** Wrestling/TheUndertaker's {{kayfabe}} brother Wrestling/{{Kane}} would eventually be targeted by an impostor; though this was when Kane had unmasked, while fake Kane was wearing Kane's old costume (including a shirt, mask, and wig). Fake Kane was also a bit shorter.
* Before he formed Right To Censor, this was Wrestling/StevieRichards' entire gimmick, imitating The Brood, the Dudleyz, [[Wrestling/MickFoley Dude Love]], Val Venis, among others. [[Wrestling/{{Goldust}} Dustin Rhodes]] also had a similar gimmick with "The Artist Formerly Known as Goldust" a couple years earlier, coming out as "[[Wrestling/TripleH Hunterdust]]", "Dustydust", "Chynadust", "Dust Lovedust", and "Sabledust".
** Charlie Haas and the Big Show also did stints where their gimmick was imitating other people's gimmicks.
* When Sin Cara found himself suspended by the Wrestling/{{WWE}}, a new Sin Cara soon appeared, with the commentators noticing that the newcomer looked quite a bit larger and wrestled a very different style than the original. Soon enough, the real Sin Cara would return, and the impostor would reveal himself as Hunico, and explain that he tried to steal the Sin Cara identity because he felt Sin Cara had stolen the Mistico gimmick from him when the two were wrestling in Mexico.
* During his tenor in the [[Wrestling/{{CZW}} Combat Zone]], "Sick" Nick Mondo's usually had a boy in the audience who dressed just like him. This boy would go onto pattern his wrestling career after Nick's as Rory Mondo.
[[/folder]]

[[folder:Tabletop Games]]
* The West End Games ''Franchise/StarWars'' roleplaying game adventure "Tattooine Manhunt" introduced a knockoff Boba Fett named Jodo Kast. Kast wore Mandalorian armor, but it didn't have as much gear as Fett's and a slightly different color scheme. Originally intended as a stand-in for [=GMs=] who wanted a Fett-like character at a lower power level, the Expanded Universe introduced the idea that Kast traded on Fett's reputation, impersonating him to take jobs from people who had never met the man. It came back to bite him when Fett caught him in a trap, poisoned him, and blew him up.

[[folder:Video Games]]
* ''VisualNovel/{{Phoenix Wright|AceAttorney}}'': An unusual variant occurs in the last case of ''Justice For All'', where Matt Engarde, who is not a masked hero, but plays one in ShowWithinAShow 'The Nickel Samurai', is implicated in a murder by a CostumeCopycat dressed in his samurai outfit.
* In ''VideoGame/UltimaIX'', reports of things the Avatar hadn't done come back to him. Eventually you can confront an extremely unstable fanboy (if you know where to look, you can actually find him and figure it out much sooner,) who is a dead ringer, except for his voice. He has so far miserably failed in every attempt to be just like the Avatar, and the Avatar can attempt to talk him into pursuing more realistic (and mentally healthier) goals.
* ''VideoGame/SonicTheHedgehog2006'' had Mephiles, who took on Shadow the Hedgehog's form by using his Shadow. The only differences were the lack of color, no mouth, and lizard-like eyes.
* The downloadable multiplayer title ''Gotham City Impostors'' allows players to join either a group of Franchise/{{Batman}}-inspired vigilantes or a [[SelfDemonstrating/TheJoker Joker]]-aping crime gang and battle each other across Gotham City.
* Conrad Verner has a replica N7 hardsuit in ''VideoGame/MassEffect2'' and has taken to pretending to be a badass mercenary and part of Shepard's squad. When Shepard lampshades how implausible it is that he's gotten away with this for so long, particularly since he doesn't appear in ''any'' military records, Conrad explains that he just tells people he's "deep cover". Shepard can convince him to "retire" and let them take up the job of protecting the Galaxy.
* In ''VideoGame/{{Thief}}'', Garret at one point snarks over a guy pretending to be him.
-->"So that's the famous Garret. Guess he's not as good-looking as I heard."

* In ''Webcomic/BobAndGeorge'', [[http://www.bobandgeorge.com/archives/000523c they dressed up the Author to look like Megaman, who's now out for]] {{Revenge}}. Good thing he's TheDitz.

* In ''Literature/{{Worm}}'', [[spoiler:Coil i.e. Calvert]] replaces [[spoiler:Skitter]] with a highly-convincing body double as part of his plot to [[spoiler:keep Dinah over Skitter's objections]].

* Happened on an episode of ''WesternAnimation/TheBatman''. The impostor was actually Joker.
-->'''Joker''': Wheeee! I'm the Batman!\\
'''Penguin''': Yeah. See, the thing is... you're not.
** This was obvious to ''everyone'' as the costume was completely different ([[{{Homage}} being based of a completely different Batman's design]]), and the problem was that he decided to take up "crime fighting"-- as in he finds people who make incredibly minor misdeeds, gasses them, and then tries to force the Mayor into ''paying him for it''.
* An episode of the ''Franchise/{{Zorro}}'' AnimatedAdaptation had the captain order one of his men to impersonate Zorro, and "capture" him when the governor is visiting. But when the governor insists he be tried in his presence, and the captain complies, "Zorro" feels a bit betrayed and when the real Zorro saves him, he leaves to become Zorro somewhere else.
* Kevin in ''WesternAnimation/{{Ben 10}}'' returned as this, having absorbed some of Ben's alien transformations.
* Seen in the episode "One Jem Too Many" of ''WesternAnimation/{{Jem}}''.
* On ''WesternAnimation/TheSpectacularSpiderMan,'' the Chameleon pulls this off, but Peter is able to clear his name when he takes him down in the middle of a high-class event. Later Venom does the same thing, and Peter even {{lampshade|Hanging}}s the fact that it happened twice. (Though Capt. Stacy at least recognized that Venom is much bulkier than Spider-Man.)
* An episode of ''WesternAnimation/ThePowerpuffGirls'' had three escapee criminals disguised as the girls. [[EasyImpersonation Grown men in dresses were able to impersonate kindergartners and fool the whole town.]]
* Pulled off exceedingly well in ''WesternAnimation/IronManArmoredAdventures'' due to Madame Mask having access to a device that allows her to shape shift. The effect was convincing enough that it fooled one of Tony's best friends.
* When ''WesternAnimation/KimPossible'' and family visit relatives in Montana, Kim finds her cousin Joss's hero-worship of her includes dressing in her mission outfit. Every other member of her family has worn the same outfit while joining her on a mission; the ChristmasSpecial has Kim's parents, brothers, and grandmother all able to find that outfit at a moment's notice.
** Justified in that her mission clothes have been noted to be a standard, off-the-rack ensemble on a number of occasions (it was even explicitly a plot point a couple times).
*** One episode ("Kimitation Nation") even had it turning into a fashion craze called "Kim-Style" that everyone was into, even pets like Rufus and guys ("Kim For Him"). When Kim was persuaded to go out in the style she originated [[AlphaBitch Bonnie]] criticized her for ''[[YourCostumeNeedsWork not being able to carry off the look]]''. By the end of the episode Kim Style goes out of fashion in order to make way for the new [[spoiler: Ron Style]].
* ''WesternAnimation/ReBoot'' has [[spoiler: Megabyte]] use his new shapeshifting powers to impersonate Bob. However, he looks like the ''original'' Bob, lacking the web scars, possessing the [[TheOtherDarrin original voice]], and wears the original uniform instead of the real Bob's shiny new Glitch-Bob uniform. [[spoiler: Megabyte]] uses this to his advantage to convince Dot that he's the real deal and that Glitch-Bob is the copy. [[spoiler: Megabyte]] even gets Glitch-Bob to suspect that ''he'' might be the copy. {{Justified|Trope}} when it's eventually revealed that [[spoiler:Megabyte had actually absorbed some of Bob's data when he crushed Glitch, which allowed him to simulate a nearly perfect disguise.]] Combine this with the fact that [[spoiler:Megabyte is a MagnificentBastard]], and you can see just why this trick actually worked.
** Later subverted by Glitch, who [[spoiler:sees through Megabyte's disguise and then attaches to him to reabsorb Bob's stolen data and return it to its rightful owner. Without this data, Megabyte]] couldn't maintain his disguise and was revealed, while Bob regained his original uniform and voice.
* Tap Tap the Chiseler in ''WesternAnimation/{{Underdog}}'' did this in both his appearances.
* ''WesternAnimation/BatmanTheBraveAndTheBold'' episode "Night of the Batmen!" played this for laughs. Comicbook/{{Aquaman}}, ComicBook/GreenArrow, [[Comicbook/{{Shazam}} Captain Marvel]], and ComicBook/PlasticMan all dress up like Batman after the real one is injured. The costumes are more their own costumes modified to look like Batman's. [[RecursiveAdaptation The comic the episode was based on, which tied into the show]], featured more people joining in at the end, including ComicBook/BlueBeetle and ComicBook/BlackCanary.
** There was also an episode featuring Batman of Zur-En-Arrh, though he actually ''was'' just an IdenticalStranger who lives on another planet. This is {{Hand Wave}}d as being perfectly plausible in such a huge universe.
* The Franchise/{{Superman}} dressing as Franchise/{{Batman}} example was used in the episode "Knight Time" of ''WesternAnimation/SupermanTheAnimatedSeries''. Batman being ''invincible'' served to spook the villains of Gotham even more, enhancing Batman's legendary status.
* When Spider-Man meets Deadpool in ''WesternAnimation/UltimateSpiderMan'', Deadpool thinks that Spidey based his costume on his, and finds it flattering. Naturally, Spider-Man has no idea who Deadpool is.
