Basically, when someone looks like a RedShirt, a {{Mook|s}}, or even just an InnocentBystander, but [[SubvertedTrope turns out to be]] a MauveShirt, or even TheHero or the {{Villain}}, with few or no clues beforehand.

Often involves MookPromotion.

Compare AscendedExtra (where the promotion in importance happens in an adaptation), ChekhovsGunman (where a character is introduced in passing, but is deemed unimportant until later), TheDogWasTheMastermind.

If the supposed Red Shirt is a well-known actor, this may overlap with NarrowedItDownToTheGuyIRecognize.

Compare NonProtagonistResolver.

Contrast DecoyProtagonist, DiscOneFinalBoss.

[[folder:Anime & Manga]]
* The Young Conducter / Claire Stanfield / Vino / Rail Tracer of ''LightNovel/{{Baccano}}''. The audience is led to believe that he died in the second episode, and has no reason to suspect otherwise until [[WhamEpisode the ninth episode]], despite his heavy involvement in between. To really get the point across, he's one of the [[LoadsAndLoadsOfCharacters 23 characters who appear in the opening credits]], but he isn't one of the 17 identified by name. The entire Martillo family appears to be dead after being gunned down by Szilard. A few episodes later, it is revealed that [[{{Immortality}} nothing could be further from the truth]].
* The first episode of ''Anime/HeartcatchPrettyCure'' introduces the VictimOfTheWeek, Erika. Hey, wait a minute, [[SpoilerOpening why is she so prominent in the opening credits]]?
* In the second chapter/movie of ''LightNovel/KaraNoKyoukai'', a seemingly random student at Shiki's school makes a cryptic statement to her in the hallway. Kokutou soon mentions he was at a party for a student named Lio Shirazumi, who was dropping out of school. Neither the name nor the person are ever mentioned again. You later realize that the random student was Shirazumi and that he is actually the murderer behind the events of both the second and seventh chapters. Somewhat less of a surprise in the movie, because Shirazumi is voiced by Creator/SoichiroHoshi, so you figure he's going to show up again and be important later.
* Mikael from ''Anime/ImGonnaBeAnAngel''. In the first season he was nothing more but a background character, sometimes appearing only at the very end of episode or not appearing at all. In the second season, it was revealed that he is one of the three main individuals important to the plot, then he got promoted to a final villian and at the end, it turned out that ''he'', in fact was the main hero of the show -- confirmed by WordOfGod.
* Angela from ''Manga/BlackButler'' appears as the [[{{Meido}} maid]] to the BigBad of Episode 7. She's "beautiful" ([[GenericCuteness which is standard fare]]) and a domestic servant -- that was pretty much it. TheStinger, however, is ominous enough and subsequent episodes make it obvious that she's the BigBad of the season.
* In ''Manga/OnePiece'', [[WorldsStrongestMan Whitebeard]] is first introduced during a scene in which a new recruit of fellow Yonko Shanks boards his ship to discuss a meeting between the two. The first crew member to speak to the recruit ([[SmallNameBigEgo who had been bragging about his fame]]) is a lazy-looking blonde man who mentions that he's never heard of the recruit before. This crew member only has the one line, and is even drawn in a generic, sloppy way in the anime adaptation (complete with incorrect color palette). Several hundred chapters later, and the crew member is revealed to be Marco "[[RedBaron The Phoenix]]", Whitebeard's first mate, and a pirate strong enough to fight two admirals to a standstill!
* ''Manga/TokyoGhoul'':
** The child-like Eto, a seemingly-minor member of Aogiri Tree that acts like a TagAlongKid to the higher-ranking members. Instead, she's not only the [[KingIncognito true leader]] of the organization, she is the legendary One-Eyed Owl and the enstranged, HalfHumanHybrid daughter of [[BigGood Yoshimura]]. Come the sequel, she steps out of the shadows and begins manipulating people openly. Eventually, she even reveals herself to her followers.
** Nimura Furuta, an easily-missed young Investigator introduced as the subordinate of the deranged, ObviouslyEvil Shiki Kijima. Once his superior is killed in action, however, he reveals himself to be one of the major players of the story -- a TykeBomb in the service of the organization '''V'''. He's spent the last several years infiltrating various groups, posing as a ghoul named "Souta" in order to join the Ghoul Restaurant and the [[WildCard Clowns Gang]]. Under this guise, he dropped the steel beams on Rize and caused Kaneki's transformation into an One-Eyed Ghoul. While working for the CCG as an Investigator, he's been aiding [[MadScientist Dr. Kanou]] in his experiments, and leaking sensitive information out to Aogiri. Suffice to say, it isn't clear where his true loyalties lie or what his real goals might be.

[[folder:Comic Books]]
* This was a somewhat popular technique in UsefulNotes/TheGoldenAgeOfComicBooks, and was usually PlayedForLaughs. In one of the earliest Comicbook/JusticeSocietyOfAmerica stories, for example, the heroes take down a nationwide crime syndicate whose leader turns out to be an {{Expy}} of NewspaperComic character Casper Milquetoast who had popped up as a bystander in each prior chapter of the story.
* In ''ComicBook/{{Watchmen}}'', a short, redheaded man who holds a sign that says "The End is Nigh" is often seen in the backgrounds. He blends in with many of the recurring faces, seemingly just another part of the city's colorful population. He is actually Rorschach with his "face" off to observe without revealing his costumed-vigilante identity.

* ''Film/{{Alien}}'': Albeit it's [[ItWasHisSled practically common knowledge by now]], Ellen Ripley being the sole survivor and protagonist of the movie must have been a surprise back then considering that she wasn't obviously set up as the main character of the movie (Tom Skerritt would have been a more obvious contender) from the start and that it was Sigourney Weaver's first major role.
* ''Film/TheDarkKnight'' begins with a bank robbery in which disposable thugs kill each other one after another. Finally just two are left, and one realizes the other guy probably has orders to kill him, so he tries to strike first. Unfortunately for him, this other mook is SelfDemonstrating/TheJoker, and he was already expecting it and planning to kill the NEXT guy who was coming to kill this guy for him.
* Happens in ''[[Film/BillAndTed Bill & Ted's Excellent Adventure]]'', when the two robed executioners turn out to be So-crates and Mr. The Kid in disguise, and they rescue Bill and Ted.
* In ''Film/TheThreeMusketeers1993'', when D'Artagnan is led to the chopping block, two of the execution personnel turn out to be Porthos and Aramis in disguise, and they're there to rescue him with help from Athos (who takes care of the escape transportation by appropriating the Cardinal's carriage).
* Happened in ''Film/MortalKombat'' near the end, when Shang Tsung was doing some kind of ceremony with the kidnapped Sonya. Some random "evil" cloaked dudes turn out to be Johnny Cage and Liu Kang in disguise. Cue butt kicking.
* The "two weeks" scene in the original ''Film/TotalRecall1990''. Averted in the [[Film/TotalRecall2012 2012 remake]]. The "two weeks" lady is normal. She repeats the phrase but only because she was thinking of something else when asked, then corrects herself. The guy after her, though...
* In ''Film/TerminatorGenisys'', [[spoiler:Alex/Skynet]] can be seen standing among the watching Resistance fighters as Kyle Reese approaches the time machine. The camera does linger on him for a moment, but there's no reason to think anything of it. [[spoiler:Until he attacks John Connor...]]

* The Worker from ''Literature/AtlasShrugged''. He is, of course, John Galt.
* Tigerclaw was a random prologue character in the first ''Literature/WarriorCats'' book. Fans now know him as the BigBad.
* ''Literature/GalaxyOfFear'' likes these. Wedge Antilles is not a minor pirate but a major Rebel, though any reader who recognized his name would guess that. Domisari seems like an affable bystander and is Vader's assassin.
* ''City of the Chasch'' by Jack Vance introduces the command staff of a starship. They send a pair of scouts to explore the mysterious planet below. The reader is likely to assume the scouts are doomed (and one of them is), but one becomes the main character of the novel and its three sequels. The starship explodes in the first chapter.
* Rashim Anwar joining the team in ''Literature/GatesOfRome'' was completely unexpected. He seemed to just be another OneShotCharacter until he was dragged off by the team back to the archway (and into subsequent books).

[[folder:Live-Action TV]]
* ''Series/{{Angel}}'': Angel encounters each one of the members of The Circle of the Black Thorn separately throughout Season Five.
* ''Series/GameOfThrones'': When Bronn is first introduced, he looks like just another sellsword. The camera doesn't linger on him very much, and he doesn't even have any features or costumes to distinguish him from a commoner other than a dry wit. Then he offers to be Tyrion's champion at the Eyrie, and proves to be more than just a mook.
* John Sheppard in the ''Series/StargateAtlantis'' pilot. When the famous O'Neill is flying in a helicopter to meet Weir and company, you pay little attention to his pilot, even when he's given a name. Then he wanders into the Antarctic outpost and activates the control chair by accident, and presto! He's TheHero, ready-made. However, Sheppard has already distinguished himself by managing a HighSpeedMissileDodge in an ordinary helicopter, which is why O'Neill gave him top clearance in the first place.
* At the end of the first series of ''Series/{{Blackadder}}'', two servants standing in the background turn out to be Percy and Baldrick, who proceed to rescue Edmund... [[BlackComedy almost]].
* Jonathan from ''Series/BuffyTheVampireSlayer'' starts out as just a generic Sunnydale High Student/Monster Fodder, being used pretty much as scenery. Then he gets a handful of episodes where his insignificance is played up for all it's worth. Then he becomes a major character. Then he's murdered by one of his best friends.
* Seska from ''Series/StarTrekVoyager''. She was originally just a red shirt that appeared in a couple episodes as a member of Voyager's crew. As it turns out, she is the main antagonist of the first two seasons.
* Megan from ''Series/MadMen''. For over half the season, she's just a secretary/receptionist at Sterling Cooper Draper Pryce, albeit one who was more stylish than the others. By the end of the season, she's Don Draper's fiancee.
* "Jim from IT" in BBC's ''Series/{{Sherlock}}'', who appears as Molly's boyfriend, and whom Sherlock quickly dismisses as gay after Jim gives him his number. Turns out he's actually Moriarty himself.
* Marlo Stanfield from ''Series/TheWire''. The first time viewers see him, he looks like an average corner hustler, and he's only shown for a couple of seconds. The first few times he's mentioned, the police on the detail immediately dismiss his crew as a low-tier outfit. Later, it becomes clear that Marlo's crew is actually extremely capable and becomes the dominant criminal force in Baltimore.
* ''Series/DoctorWho'': In "[[Recap/DoctorWhoS34E1DeepBreath Deep Breath]]", companion Clara is seemingly abandoned in the bowels of a spaceship by a manic and unreliable Doctor undergoing regeneration trauma. She is repeatedly menaced by one particular clockwork android wearing a skinned face resembling the previous actor to play the part of the Doctor, until the suspension has been milked dry, at which point the "android" rips its face off to reveal the new Doctor, with his wits about him for once.

* Taken to the extreme in the first chapter of ''Manhwa/ShinAngyoOnshi''. The main character of the series appears only as some henchman of the unknown evil lord of the city. In chapter 2, after it turns out that the supposed hero from chapter 1 was the evil lord all along, the true main character reveals his identity and kicks some ass!

[[folder:Professional Wrestling]]
* Often, ProfessionalWrestling does this, with a {{Jobber}} that scores a fluke victory and goes on to make something of himself. See: [[Wrestling/SeanWaltman The 1-2-3 Kid]] (later known as [[XPacHeat X-Pac]]) and Wrestling/BarryHorowitz in Wrestling/{{WWE}}, Wrestling/{{Goldberg}} in Wrestling/{{WCW}} (who actually started his win streak with his first televised match, despite getting the JobberEntrance), Wrestling/MikeyWhipwreck in the original Wrestling/{{ECW}}, and Colin Delaney in the WWE {{revival}} thereof. Another popular bit is a fan that somehow gets involved in the action and ends up wrestling; WWE did this bit with Wrestling/SteveBlackman, Zach Gowen, and Wrestling/SantinoMarella, as well as having "celebrity guest" Lawrence Taylor get involved this way.

* In ''Theatre/TheGondoliers'' by Creator/GilbertAndSullivan, the girls who will be the gondoliers' love interests are chosen by a game of blind-man's-buff. Before they are tagged in the game, the female leads of the play have no solos and are not distinguished from the rest of the chorus in any way.

[[folder:Video Games]]
* This trope is what makes the Imperial Guard campaign of ''[[VideoGame/DawnOfWar Dawn of War II: Retribution]]'' so satisfying. The faction universally considered the weakest and the biggest joke in the entire setting, usually existing only to be [[RedShirtArmy utterly crushed to display how awesome the opposing group is,]] can go on to single-handedly defeat fallen Space Marines, escape a planet undergoing [[EarthShatteringKaboom Exterminatus,]] survive a [[EverythingTryingToKillYou Space Hulk,]] and finally wind up defeating a [[BigBad demon]].
* In ''VideoGame/FinalFantasyVII'', one of the Shinra guards in some flashbacks turns out to have been Cloud the whole time.
* Marx from ''VideoGame/KirbySuperStar'', who at first glance appears to be nothing more than a generic resident of pop star. Turns out, he was actually the BigBad who staged the whole thing, and was manipulating Kirby into awakening Nova so he could use its power to seize control of pop star. Especially since unless you waited at the title screen, he doesn't even appear in the game proper beforehand.
* In ''VideoGame/{{Persona 4}}'', the SortingAlgorithmOfEvil runs: Mitsuo, a creepy kid who shows up once on your first day of school and appears in the shopping district every now and again, Namatame, a character mentioned in the throwaway news reports near the beginning of the game and sometimes shows up around town, Adachi, Dojima's bumbling PluckyComicRelief of a partner, and Izanami, the gas station attendant who greeted you at the beginning of the game.
* When the Fold take over the nanite-controlled supervillains in ''VideoGame/MarvelUltimateAlliance 2'', Bullseye kills a large number of Red Shirts with [[DeadMansHand his lethal playing cards]]. The only one that gets back up? A disguised Comicbook/NickFury (who turns out to be an LMD, as per usual).
* ''VideoGame/ProfessorLaytonVsAceAttorney'' features a new "Mob Trial" system, where Phoenix has to cross-examine several witnesses at once. To keep this from being too overwhelming, the individual witnesses in each "mob" are generally flat, generic characters with very basic portraits and personalities. Of course, in the first trial involving the system one of the seemingly generic witnesses turns out to be the real killer. They get a lot more expressive after you start to PullTheThread.

* Played with in ''Webcomic/TheOrderOfTheStick'', where two Samurai [[YouShallNotPass holding off bad guys for the heroes]] turn into supporting characters as soon as we [[NominalImportance learn their names]]. In fact, one of them had been mortally wounded just as he was about to introduce himself, and as he lay dying, he happened to mention his first name, then immediately realized it was OnlyAFleshWound. He decided to save revealing his last name for an emergency. Also, [[MemeticBadass O-Chul]].
* In ''Webcomic/ErrantStory'', an inept and cowardly guard from the Veracian Church, named Sandel, suddenly turns out to ''actually'' be an undercover spy for the Ensigerum Time-Ninja-Monks! Still only a MauveShirt, but that's a hell of a lot better than being an NPC Guard.

[[folder:Web Original]]
* The French webnovel ''Les Aventures de Morgoth'' has a secondary character named Tiberius Kenny Redshirt, who not only survives but becomes quite a badass.
* This trope is almost universally played straight in [[Franchise/TheSlenderManMythos Slender Man stories.]] Notable instances include Tim from WebVideo/MarbleHornets, who is secretly Masky, Brian from the same series who is secretly the Hooded Man, and also totheark, and much more surprisingly Kevin from WebVideo/TribeTwelve, who turns out to be none other then the Observer.
* ''Podcast/TheAdventureZone'' has Barry Bluejeans: first encountered as an irrelevant mercenary hired by [[AdaptationalVillainy Gundren]] and presumed dead in the destruction of Phandalin by the end of the first arc. Over fifty episodes later, he is revealed to be one of the most important characters in the entire show, having traveled to the current universe aboard the same IPRE ship as the protagonists.

[[folder:Western Animation]]
* In many ''WesternAnimation/LooneyTunes'' and Creator/TexAvery cartoons, a silly character keeps appearing out of nowhere as a RunningGag. At the end, the villain gets fed up and demands the character tells him who he is. He responds, "Don't you know? I'm the hero", then dispatches the villain with a HyperspaceMallet.
* In ''WesternAnimation/StarWarsCloneWars'' Shaak Ti is introduced as a member of [[CListFodder the squad of Jedi that Grievous soundly defeats]]. She survives, and goes on to play a major part in the Battle of Coruscant, protecting Chancellor Palpatine. Not only that, she survives for another ''17 years'' after Order 66, when the vast majority of the Jedi (including ''all'' Jedi except Shaak Ti who were present in the Jedi Temple at the time) were killed. This is especially notable, as one of the deleted scenes from ''Film/RevengeOfTheSith'' would have shown her being killed by Grievous before Order 66 was ever executed.
* Used in the ''WesternAnimation/AeonFlux'' episode "War"; each time one kills a DecoyProtagonist and becomes a DecoyProtagonist him/herself.
* During Book 3 of ''WesternAnimation/TheLegendOfKorra'', Kuvira appeared in the background of many scenes as a common soldier in Zoafu, before she is introduced during the season finale. In Book 4, she is revealed as a [[VillainWithGoodPublicity charismatic tyrant]] who is determined to conquer the whole Earth Kingdom and eventually the world.
