->'''Raphael''': [stabs Foot Soldier] [[http://clang.ytmnd.com/ "Clang?" Did you say "Clang?"]]\\
'''Michaelangelo''': Check those dudes out! [cue sparking]\\
'''Donatello''': "Dudes" nuts, [[MechaMooks they're robots!]]\\

-->-- ''[[WesternAnimation/TeenageMutantNinjaTurtles1987 Teenage Mutant Ninja Turtles]]''

So there's this person you've met. They look like a human, they act like a human, they talk like a human, and in your mind, they're very much a human.

Then they get wounded, and instead of bleeding, they're releasing sparks. Or maybe you catch them doing something no human should, like [[UnusualUserInterface changing stations by blinking]], or [[SuperStrength lifting a car]].

Apparently, the human you've been with [[TheyLookLikeUsNow was one of them]] [[HollywoodCyborg cyborgs]], RidiculouslyHumanRobots, or MechanicalLifeforms.

At this point, one of two things may happen.

If the character is an enemy, [[NotEvenHuman this is the signal]] for TheHero to go all out in battle. After all, [[MechaMooks it's a robot]], who cares if it gets killed?

However, if the character is a friend, this will lead to much shock and/or angst for everyone as they ask themselves WhatMeasureIsANonHuman This may include a HeroicBSOD if [[RobotMe even the robot]] [[TomatoInTheMirror doesn't know]].

A specific kind of GlamourFailure. For the alien and other organic creature version of this trope, see AlienBlood and BizarreAlienBiology. Occasionally appears as a {{Subversion}} of MortalWoundReveal - the robot ''should'' have died, but because of its non-biological nature, it won't die, causing much in the way of OhCrap moments.

Compare UnroboticReveal and AnimatedArmor.

'''Spoilers ahoy, so be wary.'''

!!Examples

[[foldercontrol]]

[[folder:Anime and Manga]]
* In ''Anime/MagicalGirlLyricalNanohaStrikerS'', one of the characters, [[spoiler:Subaru Nakajima]], walks out of an explosion, covered in blood and one arm missing a large chunk of flesh, revealing the cybernetics underneath, during her scene of UnstoppableRage. Interestingly, there's no ArtificialHuman-related angsting here, partly because most of the ''Nanoha'' cast aren't human, and have no problems at all accepting it.
** And unlike [[spoiler: Fate and Erio]], [[spoiler:Subaru and Ginga]] had a loving family, and complete knowledge of their origins long before the series even began.
** Hell, by this point in the series, the Bureau probably has "So you're not exactly what's traditionally considered human, that's okay because you're a person too and we support you" pamphlets. (Probably written by Fate and Nanoha.)
*** Happens again in the PSP games, [[spoiler: The Florian Sisters are full androids.]]
* Happens in ''ArmitageIII Dual Matrix'' with the titular character, made worse by the fact that it's her kid that sees it and becomes immediately afraid afterwards.
** Happens to Armitage and [[LaughingMad D'Anclaude]], among others, in the original series; Ross Sylibus' ArtificialLimbs are revealed this way, as well.
* [[spoiler:Bartholemew Kuma]] of ''OnePiece'' was revealed as a cyborg this way.
* The MIB chasing after the Crescendolls in ''Anime/{{Interstella 5555}}'' are revealed to be robots when, after an explosion, parts of their skin burn off and reveal metal.
* In ''BubblegumCrisis 2033'', Largo's boomer status - which had been implied before - is confirmed when Leon shoots him in the hand, leaving a small hole with sparking metal visible inside.
** The first episode has this happen to the kidnapped little girl, who is as surprised as anyone else that she's a Boomer with the Phlebotinum to control the military's {{Kill Sat}}s.
* In ''DominionTankPolice'', Annapuma loses her arm in an explosion, revealing her metallic skeleton. This causes Leona to exclaim, [[RantInducingSlight "Mechanical love dolls?!"]]
* A variation occurs in ''KaraNoKyoukai'' when [[spoiler:Shiki]]'s arm gets possessed, and we see the skin covering melt off to reveal that it's really a puppet arm. The rest of [[spoiler:Shiki]] is human, but the arm is artificial.
* [[spoiler:Major Montana Max]] in ''{{Hellsing}}'' after being shot by Seras.
* After being on the receiving end of a reflected fire spell, Mubyou in ''WagayaNoOinariSama'' is revealed to be a robotic duplicate of the ''real'' Mubyou. Since the real Mubyou is always WalkingTheEarth, she created a few puppet copies of herself to work in the lands she's not currently in. Seems the duplicate Mubyou just wanted to be acknowledged for her work.
* In the finale of ''CoyoteRagtimeShow'', Madame Marciano is injured and revealed to be a cyborg. Then again, being the TrulySingleParent of twelve {{Robot Girl}}s, is it really that surprising?
* At the end of one episode of ''{{Yu-Gi-Oh 5Ds}}'', a flying spinning spike of doom flies towards [[ManipulativeBastard Rex Godwin]]. He catches it with his hand seeming to suffer no ill effects to the total shock of everyone watching... turns out his arm is robot. [[spoiler: Coupled with the fact he possessed a severed arm in a test tube with a Dragon's Birthmark on it, this led some people to suspect that he may have been the 5th Signer. However, it turned out he wasn't the only one missing an arm...]]
** [[spoiler: Ghost]] is revealed to be a robot after it loses to Yusei and crashes. When the lads go to help it, Crow touches it's shoulder, and it's arm falls off.
** [[spoiler: Placido]], both when he combines with his D-Wheel, and later when he is blown apart at the waist.
** Inverted in the Third season of the original ''Anime/YuGiOh''. The gang meets up with a robot monkey, but don't realize that it's [[spoiler: Honda]] until later
* Zeo in ''BeyBlade''.
* This occurred in ''NegimaNeo'' during the re-telling of the battle between [[TheHero Negi]] and [[OlderSideKick Asuna]] against [[VainSorceress Evangeline]] and [[RobotGirl Chachamaru]]. Chachamaru uses herself as a [[TakingTheBullet shield]] to [[DivingSave save]] a [[KindHeartedCatLover group of cats]] which had gotten caught in the fray, causing her shoulder and upper thigh to spark and a metallic skeleton to show beneath her skin. In the regular manga, she simply showed them her JetPack by accident.
** I'm pretty sure that in the manga, it wasn't even an accident. She never makes any indication that she's attempting to hide her robotic nature; she even has incredibly obvious antenna ears and pulls out the jetpack in a public place to get a kid's balloon out of a tree. Everyone else (except [[MetaGuy Chisame]]) is just [[WeirdnessCensor oblivious]].
* Parodied, like everything else, in ''Anime/ExcelSaga''. Ropponmatsu II gets shot in the head, and the circuitry underneath reveals she's a robot. Excel is honestly surprised by this, despite obvious signs of it earlier in the episode. Ropponmatsu herself considers it obvious, and asks how many people shoot missiles from their knees.
** Well, considering [[TheDitz how stupid]] Excel is, it's no surprise she hasn't caught on.
* In ''Manga/FullmetalAlchemist'', Ed has an [[RoboticReveal automail reveal]] when his right arm gets attacked by Cornello's pet chimera. In ''Brotherhood'', the reveal is done by a rogue alchemist trying to freeze his blood in that arm.
** Izumi also finds out that Al is [[AnimatedArmor just an empty suit of armor]] by ''throwing'' him, and concludes that Ed has an automail leg by the fact that ''his steps sounded different'' when they were sparring. She's just that good.
* The ''TrinityBlood'' novels drop several hints about Father Tres Iqus not being human, however it is only officially revealed when he is shot through the arm and his circuits are revealed.
* In the final episode of ''Anime/TheBigO'' it turns out that Big Ear, the mysterious informant who's always reading a newspaper when he's spoken to, is an android.
* Used to chilling effect at the end of a scene in ''GhostInTheShell 2: Innocence''; after Batou and Togusa finish a conversation with [[spoiler: a forensics scientist]] about the nature of the UncannyValley, her face flips open to reveal mechanical insides.
** If you look carefully, you can deduce her cyborg status by noting that she wears short sleeves in extreme cold, and her breath isn't visible even though Togusa's is.
* In ''GallForce'', the crew find out about an advanced android when Pony forces the information out of the OX-11, to be confirmed moments later, when [[spoiler: Catty makes a HeroicSacrifice, and her clothes are burned away to reveal the android beneath.]]
* In ''OsamuTezukasMetropolis'', Ken'ichi is the very last person to find out or even consider that Tima was a robot. She was introduced as this at the beginning of the film.
* In ''{{Gundam 00}}'' [[spoiler:half of Lichty's body is revealed to be cybernetic when he saves Christina's life at the cost of his own.]] Since it adds very little to his character, this was most likely due to the fact that it would have looked really gruesome if a normal human body had been exposed to GN particle beam like that, and wouldn't have passed the censors.
* ''Anime/AKB0048'''s Mayu Watanabe looks like just another member of the pop idol group...until she raises her arm and a missile launcher complete with aiming visor swings up out of it. This is not really focused on in the show, though.
* In the Votoms OVA The Last Red Shoulder, one of Chirico's old friend, Byman was seemingly untouched by their former treacherous commander Pailsen (Their leader Gregor was wounded and scarred during a failed hit attempt, while other member Muza had his entire family slaughtered while he wasn't home, and Chirico himself was set up to be marked a traitor), until Chirico (who noticed Byman refused to punch Muza with his right hand when a fight broke out) tossed a lit piece of firewood at him, burning off his sleeve and revealing a robotic arm, as Pailsen had tortured and cut off his entire right arm. They promptly stop mistrusting him after that(Muza believed he had no business being with their group when his life was seemingly fine)
[[/folder]]

[[folder: Comic Books]]
* The comic's cover showed the new ''Comicbook/{{X-Men}}'' (Storm, Wolverine, Nightcrawler, Colossus, and Banshee) fighting the original Comicbook/{{X-Men}} (Jean Grey, Cyclops, Angel, Beast, and Iceman). The fight actually happened in the issue, with the new X-Men unwilling to fight all-out against their friends. But Wolverine realized that the original X-Men were robots because they didn't smell right. The robots were reduced to scrap metal pretty quickly after that.
** X-men enemy Arcade makes robots convincing enough that his appearances in comics usually end up being robots. He was so good at this that when he made a double of Nightcrawler, Mystique mistook it for her son and couldn't bring herself to kill it.(Had no problem vaporizing her daughter Rogue though)
* Anna, from the ''{{Gen 13}}'' series. She's a demure maid who cooks and cleans for the group, looking very much annoyed when her carefully cooked breakfast goes ignored in favor of various snacks, junk food and cold pizza. Then she turned out to be an assassin droid with concealable blades and weapons of destruction.
* Adam Aaronson, ''Machine Teen'', initially believes himself to be an OrdinaryHighSchoolStudent. His robotic nature is revealed when he gets damaged playing football, but he himself is programmed to think of it as a normal injury.
* In ''TopTen: The 49ers'' the IronMan CaptainErsatz is revealed, when his armour is damaged, to be a [[DoesThisRemindYouOfAnything robot passing as a human]] to escape [[FantasticRacism anti-AI prejudice]].
* DoctorDoom has a battalion of robot duplicates, all programmed to act as if they were him, unless a) there's more than one of them in the room, or b) the real Doom is present.
* James-Michael's [[spoiler: parents]] in OmegaTheUnknown.
* This was a WhatCouldHaveBeen in ''ComicBook/SonicTheHedgehog''. Sometime after the Endgame arc, the original plan was that Sally had been DeadAllAlong since that arc, and the Sally that's been in the comic since then was in fact a robotic clone who became self aware and ultimately rebelled against Eggman. However, this was given ExecutiveVeto, so Sally ultimately survived Endgame and the clone never appears.
* BorisTheBear, revealing to Boris (and us) that he's a robot.
* Happened a lot in the SilverAge with {{Superman}} who had robotic duplicates that could impersonate him as Clark or Superman. But in an early PostCrisis story, the first {{Superman}} is so perfectly programmed with Superman's personality that he believes he's Superman even after his robot parts become exposed. He genuinely believed he was somehow the real Superman turned into a robot.
* In the final panel of the ECComics story "Strictly Business," the husband shows how easily he could enter into a deliberately SexlessMarriage and tolerate it for three years by opening up his chest...
[[/folder]]

[[folder:Film]]
* Inverted in ''Film/TheBlackHole'' when the Cygnus' compliment of robotic crew members [[spoiler:are actually revealed to be the lobotomised remains of the human crew. With Maximilian's help Dr. Reinhardt converted them into subservient cyborgs after they tried to mutiny.]]
* The ''Franchise/{{Terminator}}'' franchise:
** ''Film/Terminator2JudgmentDay'':
*** The T-800 cuts the skin off his arm deliberately to prove to the Dysons that he isn't human.
*** At first, the T-1000 seems like it's the soldier the resistance sent back to protect John, until the Terminator shot him multiple times and he reformed afterwards.
** ''Film/TerminatorSalvation'' pretty much does this ''in the trailer.'' While we do not see the entire scene, the gist of the scene explains everything: Medic, trying to patch up a wounded soldier, is horrified when she sees Terminator circuitry, calls over [[TheHero John Connor]], who ties him up and interrogates him, before untying him when he sincerely doesn't understand why the hell he's tied up, just so he can see it for himself. Cue the horror.
** For ''Series/TheSarahConnorChronicles'', see the Live-Action TV folder.
* Beta in ''TheLastStarfighter'', when he was wounded in front of Alex Rogan's girlfriend. Moments before, Beta had been trying to convince her that he was a robot. She didn't believe him. He gets shot, shows her his circuits, and says, "See?" before chasing after the attacker.
* In the 2004 version of ''Film/TheStepfordWives'' [[spoiler:it's revealed when the main character knocks his head off that Mike Wellington is actually a robot, while it's his ''wife'' that's the programmer, an inversion from the original movie.]]
** Both film versions have the scene where Joanna confronts the mysteriously changed Bobbie and goes so far as to stab her. The Stepfordized Bobbie acts ''very'' strangely for someone with a kitchen knife in her stomach. Maybe Joanna should've done anything now, but the [[IdiotPlot plot]] seemingly required her to be an idiot.
*** Which makes the 2004 version even more stupid when you find out [[spoiler: all the Stepford Wives are human women with ''microchips''. Because microchips make a gut wound ''all'' better.]]
** The 1975 version features a chilling climax when Joanna meets her robot double.
* ''Film/{{Toys}}'': [[spoiler:Alsatia, revealed by her [[OffWithHisHead accidental decapitation]] in the climactic battle]]
* The [[Film/GodzillaVsMechagodzilla 1974 version]] of Mechagodzilla gets a reveal like this, while impersonating the real Franchise/{{Godzilla}}.
* Used a number of times in the ''Franchise/{{Alien}}'' series.
** ''Film/{{Alien}}'': Ash, the ship's medical officer. By ''bashing his head off''.
** ''Film/{{Aliens}}'': Bishop, thanks to the infamous knife-trick.
** ''Film/{{Alien 3}}'': Inverted when someone suspected of being an android is violently attacked, only to start bleeding very human red.
** ''Film/AlienResurrection'': Annalee Call. During their escape in the elevator shaft, Wren has trouble opening the shaft door. He asks for Call's gun which she readily provides, not realizing her mistake until Wren shoots her in the chest, knocking her off the ladder and into the water with a very determined xeno on the group's tail. After they take out the xeno, they are suprised when Call opens the shaft door from the other side, soaked with water. Though she doesn't want to talk about what happened, [[NoOneCouldSurviveThat Ripley saw her being hit and her light clothing betray the fact that she doesn't have body armor]]. She opens her jacket and reveals circuits and synthetic liquid instead of bone fragments and blood. Androids built by Androids are illegal so Call hid her own identity to stay alive. Needless to say, the rest of the team (except Ripley) didn't like this one bit until she proved her worth by crashing the Auriga.
* The film version of ''Film/IRobot'' has Spooner getting his arm damaged, revealing a [[{{Cyborg}} cybernetic]] limb inside. Bonus points, because the robot attacking him is ''actually surprised'' by this. More bonus points [[YouAreWhatYouHate because Spooner absolutely hates robots]].
* In ''Starchaser: The Legend Of Orin'', the villainous Zygon turns out to be a robot when Orin cuts his cheek. Although that really shouldn't have been a surprise to him, since the dude was running a [[EvilEmpire robot empire]] and was strong enough to [[NeckLift pick him up and choke him with one hand]].
* In ''[[BillAndTedsExcellentAdventure Bill and Ted's Bogus Journey]]'', done [[RuleOfThree three times]] by the "evil" Bill and Ted robot usses. The reveals lean toward terrifying, but the second time, when human Bill punches his twin, is probably the funniest. "Oww! You're metal, dude!"
* The German silent film ''Film/{{Metropolis}}'' had one of the first robotic reveals. A MadScientist creates a female robot that is identical to Maria, a woman who preaches about peace to the enslaved workers in the city who want to revolt. The real Maria is kept away as the robot inspires lust among men and violence among the workers. When the city falls to pieces, and the people decide that Maria is to blame, they tie her up to a stake and attempt to burn her to death. She laughs as her 'exterior' melts away, revealing that she is a robot.
* In a 2004 DisneyChannel MadeForTVMovie called ''Pixel Perfect'', a hologram named Loretta is created by a teenager to help his best friend's band. Loretta is thought to be human until the band's second performance, when she starts fading in and out. But, in a slight subversion, everyone loves the holographic lead singer.
* ''PoliceAcademy'' played with it in [[http://www.youtube.com/watch?v=_rftQ0asyMU this scene]].
* [[spoiler:Alice]] turns out to a humanoid Decepticon in ''Film/TransformersRevengeOfTheFallen''.
* In ''Film/{{Surrogates}}'', [[spoiler:The Prophet]] is revealed to be a Surrogate controlled by [[spoiler:the Surrogates' inventor.]]
* ''ThePresidentsAnalyst'' - near movie's end, the good guys have stormed the headquarters of The Phone Company. Finding themselves facing the company's blandly cheerful president, they're surprised to find he's an animatronic figure.
-->'''Masters:''' He's a ''recording!''
-->'''Kropotkin:''' It's like a visit with Abe Lincoln at Disneyland!
* In the 1982 film ''Android'', [[spoiler:the MadScientist who built the androids Max and Cassandra]] is graphically revealed to be an android too after his head is ripped off in a struggle and [[CranialProcessingUnit it keeps speaking until it is thrown down a trash chute.]] He keeps repeating "I'm not an android" the entire time.
[[/folder]]

[[folder:Literature]]
* In Creator/ETAHoffmann's 1816 short story, "Literature/TheSandman", the main character falls in love with a woman named Olimpia, who is eventually revealed to be a robot.
* [[Creator/IsaacAsimov Elijah Baley]] is told from the start that R. Daneel Olivaw is a robot. He refuses to believe it, however, as robots that advanced don't exist on Earth in his time -- and he has a brilliant theory about the murder of the human in whose image Daneel was built. When Daneel peels the synthetic flesh off his arm to prove himself, Baley faints ([[GeorgeJetsonJobSecurity for several reasons]]).
** And then Elijah pulls off his trick in the sequel.
** Though [[{{Foundation}} Hari Seldon]] doesn't find out that [[spoiler: Dors Venabili]] is a robot until long after they met.
* ''Literature/{{Animorphs}}'' did this a little differently. They morph dogs, and just-so-happen to run into an old acquaintance of Marco's as he's passing out fliers for the [[AlienInvasion Yeerks' front organization]], and they freak out because... ''Erek has no scent.'' Because this might be a new weapon of the Yeerks, they stalk him until he just-so-happens to get hit by a truck and his hologram shorts out for a split-second. It's not until they morph spiders (which see a different wavelength of light) that they can confirm that he's an android[[note]]Or maybe more of a cynoid in disguise?[[/note]], however. Erek turns into a fairly important minor character, as the Animorphs' spy inside the Yeerk organization and using his and his friends' holographic abilities to impersonate the Animorphs so that they can go into outer space or something without being missed.
* In "The Eleventh Voyage" of Ijon Tichy, the main character of ''Literature/TheStarDiaries'' by Creator/StanislawLem, this gets totally [[spoiler:inverted]]. Tichy, sent in a robot disguise to a planet inhabited solely by machines that are hostile to all humanity, discovers in the story's finale [[spoiler: that there is no single robot around the place. All of the alleged machines are in fact secret agents like himself, who have been exposed one by one, and forced to keep up appearances. Furthermore: the computer mastermind behind this plot shows up to be merely a humble human gofer working for the agency responsible for sending all those people on a mission to that planet]]. The story is a parable of living in a country, where everybody upholds the official ideology no one actually believes in, which was the case of People's Republic of Poland at the time when Lem wrote the thing.
[[/folder]]

[[folder:Live Action TV]]
* ''Series/RedDwarf''. in "Out of Time", Lister gets his arm cut, revealing mechanical parts. Not only mechanical, but of a model inferior to Kryten, which means Kryten technically outranks him! The whole thing is then beautifully subverted when [[spoiler: it turns out that Lister's mechanical "nature" is the result of Starbug having hit an "unreality pocket", turning Kryten briefly into a gibbering idiot as he attempts to apologize for his mis-step]].
* Franchise/StarTrek
** ''Series/StarTrekTheOriginalSeries''
*** Dr. Roger Korby at the end of the episode "What Are Little Girls Made Of".
*** And Norman at the start of "I, Mudd".
** ''Series/StarTrekTheNextGeneration''
*** In the episode "Thine Own Self", Data is amnesiac because of (nonvisible) damage, and has gone native. An injury shows the circuitry under his skin, much to the shock of all (Data himself included).
*** The episode when Data's creator's wife shows up, and while she's down on the planet she falls and turns out to be an android herself.
* There was a ''Series/StargateSG1'' episode where this was combined [[spoiler: with a TomatoInTheMirror]]...
** And a sequel to this episode: One of the villain's followers started doubting his godhood because said "god" looked surprised after killing an android.
* In the series ''TotalRecall2070'', Farve is revealed to be inhuman when he regenerates his arms' skin after having it burnt/melted by high voltage cables. He then explains that he's an Alpha android, a prototype RidiculouslyHumanRobot using WetwareCPU.
* ''Series/PowerRangersOperationOverdrive'': [[spoiler:Red Ranger Mack is revealed to be a robot built by his "father" after a computer virus that infects the Rangers' base afflicts him as well, and he's forced to be taken off-line and disassembled to get at the problem.]] Needless to say, he wasn't very happy about it.
** About ten years prior, ''Series/PowerRangersTurbo'' had an episode where the [[CousinOliver Blue Ranger Justin]] suspects that the other four Rangers have been replaced by robots. As it turns out, he's right. [[spoiler:The real sting? Justin HIMSELF is revealed to be a robot like them, when the real Justin shows up to deactivate him.]]
** In ''Series/PowerRangersSPD'', new cadet Sophie is discovered to be a robot when the Rangers walk in on her repairing the circuitry in her arm.
** ''Series/PowerRangersRPM'' [[spoiler:inverts this. Tenaya 7 is convinced she is a machine, until a cut in a fight reveals she bleeds. The camera angles play with this trope, mimicking its straight use and treating the blood as if it was the tell-tale sparking wires. In fact, the straight usage had happened earlier in the same episode to a part of her body that ''was'' mechanical, although it was to make the point that Tenaya was( as she thought) a machine.]] There's also the finale, where it's revealed that [[spoiler:around half of the citizens in Corinth are sleeper agent cyborgs, and Venjix is just about to activate them]].
* The ''Series/{{Buffy|the Vampire Slayer}}'' episode "Ted" has Ted revealed as a robot after Buffy clobbers him.
** We know that the Buffybot is a robot, but it's revealed to a vampire after he injures her, revealing electronic parts (and causing her to bang into walls).
** Likewise when Glory knocks the Buffybot's head off.
-->'''Glory:''' "The Slayer's a robot? Did everybody else know the Slayer was a robot?"
** Unnecessary for April in "I Was Made to Love You". Her behavior makes it perfectly clear to everyone that she's a robot. Which makes it EverybodyKnewAlready when her creator Warren tells Buffy something she "couldn't possibly know".
* In the ''Series/{{Angel}}'' episode "Lineage", after Wesley kills [[spoiler: his father]], the latter is revealed as a robotic replica.
* In ''Series/{{Andromeda}}'', Doyle is revealed to be an android when she cuts her hand and bleeds superconductor fluid. As a small twist, it's revealed to ''us'', but not to ''her'', since Harper programmed her with a perception filter that causes her to think it's blood.
* ''Series/DoctorWho'', "[[Recap/DoctorWhoS13E4TheAndroidInvasion The Android Invasion]]". Sarah Jane Smith's face comes off to reveal that she's been replaced by a robot.
** In "Victory Of The Daleks", [[spoiler:Professor Edwin Bracewell's]] hand gets shot off by a Dalek, revealing [[spoiler:him to be a robotic creation of theirs, so that in turn the Daleks have proof that Bracewell 'created' them. [[WhyAmITicking They also made him]] [[MadeOfExplodium as an explosive device]]]].
* The reimagined ''Series/{{Battlestar Galactica|Reimagined}}'' finds plenty of ways to reveal that characters are not quite human:
** As artificial humans in this world are mass-produced, a favourite is simply to reveal that (an)other identical version(s) of a character exist(s). This is done with [[spoiler: Boomer, Sharon, D'Anna, Cavil and Gina (in the movie)]].
** In the first Season we also get the fact that their spines glow when "getting intimate". This was dropped in later Seasons (probably because it's pretty stupid and provides a simple "Cylon detector" for humanity).
** Caprica Six simply tells Baltar she's an android; as she knows the world is about to be invaded by her fellow killer robots this is not much of a gamble.
** Leoben Conoy behaves oddly, is unusually strong and proves vulnerable to exotic radiation.
** A marooned Aaron Doral is rescued by his fellow androids.
** [[spoiler: Simon]] is seen talking with another, known, android.
** [[spoiler: Anders, Tyrol, Tory and Tigh]] are drawn together and mysteriously 'activated' when the Fleet reaches [[spoiler: the Ionian Nebula]].
** [[spoiler: Ellen]] is glimpsed by another android in a vision.
** Subverted with [[spoiler: Starbuck]]. There are many hints that she might be an android but the main thing that suggests this e.g. [[spoiler: her resurrection]] is apparently ''not'' due to [[spoiler: "downloading"]].
* In an episode of ''Series/BionicWoman'', after Jaime rescues a girl from some would-be kidnappers, the girl discovers the exposed wiring of Jaime's arm.
** In [[Series/TheBionicWoman the original series]], Jaime herself is horrified when she first tangles with the Fembots; she thinks they're just crazy doppelgangers until she rips one of their faces off during the fray, revealing circuitry and freaky lidless eyeballs. (Her later, delirious warning to Rudy about robots, after they've kicked her ass, is chalked up to bionic rejection. Until Oscar's face suddenly comes off.)
* In ''Series/{{Farscape}}'' [[spoiler: Aeryn]] is kidnapped and replaced with a bioloid copy- which is unveiled when Crichton gets wise and shoots her in the head, revealing pulsating organic machinery beneath the ruined face.
** [[spoiler: Sikozu]] reveals herself to be a bioloid as well by rotating her left eye 120 degrees as a signal to another bioloid.
* In the second season premiere of ''{{Terminator}}: TheSarahConnorChronicles'', Catherine Weaver seems to be an ordinary CorruptCorporateExecutive who has obtained [[MacGuffin the Turk]] and plans to develop it. Then the head of her company's AI division starts [[BathroomStallOfOverheardInsults badmouthing her in the men's room]]. As soon as he's alone, a [[BlobMonster liquid-metal type Terminator]] [[VoluntaryShapeshifting peels itself off]] the urinal and turns into Catherine Weaver, who kills the man with a [[ShapeshifterWeapon liquid metal finger-poke]] and a BondOneLiner.
--->'''RedShirt:''' God that Weaver bitch pisses me off.
--->''Walks up to the urinal and unzips his pants. Mrs. Weaver emerges, [[IncrediblyLamePun scaring the pants off the Red Shirt]].''
--->'''Mrs. Weaver:''' I'm sorry to hear I piss you off. ''poke'' [[BondOneLiner Believe me, the feeling is mutual.]]
* In a ''{{Sliders}}'' episode, the lead researcher for developing MechanicalLifeForms wanted to test out a way to transfer a human brain into a robot. He discovered that the procedure was already performed on himself when he was hit by a weapon.
* 1960's ''Series/{{Batman}}'' episode "The Joker's Last Laugh". Batman realizes there's something strange about a bank teller. He twists the man's nose and the top of his head blows off, revealing springs and other mechanical parts. The teller was actually one of the Joker's android robots.
* In ''Series/TheSarahConnorChronicles'', Cameron has a more subtle way of revealing herself, simply by lighting up the irises of her eyes. In this case, though, she is talking with someone who already knows Terminators exist.
[[/folder]]

[[folder:Music]]
* There is an old viral video from the early 2000's by a raper named Pete Miser called [[http://www.youtube.com/watch?v=m-HqzavQLKY Scent of a Robot]], which essentially this trope in song form.
[[/folder]]

[[folder:Tabletop Games]]
* There are rules governing this reveal ''vis--vis'' Cyborgs in ''TabletopGame/{{Deadlands}}: Hell on Earth'' and ''Lost Colony'', particularly if the deadbot in question is equipped with the "Infiltrator" package, which makes a normally pallid cadaver-with-metal-in-its-guts capable of breathing normally, bleeding, eating, and other things. When a cyborg takes enough damage, nearby characters can make a check to see if they notice anything unusual in the wound, with the roll being easier if...
-->''...Your can is continuing to fight after taking enough damage to drop a bull rhino.''
* Encouraged for Game Masters in the [[ProseDescriptiveQualities PDQ-system]] superhero game ''Truth and Justice''. Where heroes get Hero Points to trade for bonuses and to pull off impossible stunts, villains get Villain Points which grant similar bonuses and also allow them to "actually" turn out to have been a robotic double all along, and other forms of instant escape/backup plan. Villains have to be worn down in a series of confrontations to be put away for real.
[[/folder]]

* One of the characters in the first ''[[VideoGame/WildArms1 Wild ARMs]]'' game is revealed to be not quite what they seem after [[spoiler: he cuts off his arm to get away from the BigBad]]. When the others treat the injury, [[spoiler: sparks fly out, and they discover that his insides were made of the same properties as the [[MechanicalLifeforms Metal Demons]]]].
* A variant occurs in ''SuperSmashBros Brawl'' when [[spoiler: The Ancient Minister, who up until this point was considered to be a variant of one of the Big Bad's Mooks, turns out to be [[strike:a]] THE R.O.B.]]
* In ''Franchise/TombRaider: Chronicles'', in the final level you encounter suited henchmen who seem extremely tough, after causing enough damage it is revealed that they are Cyborgs and must be killed by alternative means to shooting.
* Dr. Wily at the [[YourPrincessIsInAnotherCastle next-to-last level]] of ''VideoGame/MegaMan3''. [[spoiler: Although it's kind of easy to tell because they play the regular level-ending song. It did surprise some people because this was only the first game where the bad guy was "[=Not-Wily=]".]]
* VisualNovel/{{Snatcher}} has [[spoiler: Random]] - it comes as a [[TomatoInTheMirror surprise to himself]] as well.
* Done with a twist in ''CommandAndConquer 3: Kane's Wrath'', where it is revealed that [[spoiler: the player]] is a Nod AI named LEGION. Presumably, LEGION was aware of its nature the whole time, but the player doesn't until Kane makes the revelation himself.
* One of the millions of twists in ''VideoGame/GhostTrick'' is that [[spoiler: the BigBad's assistant is an AI.]]
* In ''BatenKaitos Origins,'' the one with robotic innards is [[spoiler:Milliarde.]]
* In ''StreetsOfRage 3''[='=]s Stage 5, you fight [[spoiler:Mr. X. Why are you only on the ''fifth'' stage when you fight him? Well, upon defeating his henchmen, the top half of him burns off to reveal a robotic duplicate. The real Mr. X, who you encounter in Stage 7 (assuming you rescued the [[strike:[[{{Macekre}} General]]]] Chief of Police), has been reduced to a brain.]]
* Played straight with the final boss of the first ''Turok'' game. The Campaigner at first appears to be some sort of barbarian wizard, but as he takes damage his flesh peels off to expose his robotic structure. In some ways there is a [[WhatMeasureIsANonHuman subversion]] of this trope, as the player has already cut down legions of "real" humans by this point.
* ''VideoGame/CaveStory:'' Professor Booster apparently recognizes [[spoiler:the protagonist]] as a robot immediately, but several other characters--particularly Kazuma, and possibly the player--don't realize this until Booster points it out. In their defense, he is a RidiculouslyHumanRobot.
** With white skin, inhuman eyes, and antennae for ears.
* ''VideoGame/HenryHatsworthInThePuzzlingAdventure's'' ending has you fighting [[spoiler:Weasleby]] for a while before he suddenly twitches with electricity coming off him and his head falls out. And then [[spoiler:[[KidSidekick Cole]] pops out from the remains to reveal himself as TheManBehindTheMan.]]
* Somewhat played with in ''VideoGame/MetalGearSolid4'', [[spoiler:right before the final boss fight with him, Ocelot dramatically removes his jacket to reveal that Liquid's arm has been replaced with a bio-mechanical prosthetic, hinting that "Liquid" was artificial.]]
** In ''VideoGame/SnakesRevenge'', [[spoiler:Big Boss reveals before the final battle that he was turned into a cyborg. After he sustains enough damage, he transforms into a tall cyborg who chases after Snake across several rooms.]]
** Inverted in ''VideoGame/MetalGear2''. In an optional radio call during the final battle, Kasler tells Snake that Big Boss underwent an operation to replace his limbs with cybernetic organs. When Snake defeats Big Boss with a makeshift flamethrower, [[spoiler:he burns to death like any other person ([[VideoGame/MetalGearSolid4 he did get better]]).]]
** Also inverted in ''VideoGame/MetalGearRisingRevengeance''. [[spoiler: In a cast full of superhuman cyborgs, TheDragon Jetstream Sam is cut open to reveal that he's a normal human with almost no cybernetic enhancements.]]
* In ''VideoGame/WonderBoyInMonsterLand'', [[spoiler:the dragon you've come all this way to slay]] is revealed to be a robot, [[spoiler:possibly from space]].
* In the first ''SonicAdvance'', halfway through the fight with Metal Knuckles, his outer covering breaks off to reveal his metallic body. (Of course the fact that he was a robot was AllThereInTheManual, but only in the Japanese version.)
* At the end of ''ProfessorLaytonAndTheCuriousVillage'', it's revealed that [[spoiler:practically everyone in St. Mystere is a robot, save for a few residents such as [[GirlInTheTower Flora]] and [[GadgeteerGenius Bruno]]]].
* In ''VideoGame/StrongBadsCoolGameForAttractivePeople'', [[spoiler:Uzi Bazooka reveals himself as a robot clone of Dangeresque, Too? after being shot.]]
* ''VideoGame/ConkersBadFurDay'', being the ShoutOut-heavy game it is, throws one out to {{Terminator}} with the Haybot, who looks like your average musclebound anthropomorphic stack of hay until you stick Frankie's forks in his ass twice, at which point part of him burns away to reveal the ever-familiar image of a robotic red eye. "'''[-BUFF YOU, ASSHOLE!-]'''"
* A minor reveal in ''VideoGame/MassEffect3'': after chasing down a Cerberus agent on Mars, Vega rams her with a shuttle. Cue her emerging OutOfTheInferno... her clothes and skin burned off the robotic frame by the explosion.
* In ''VideoGame/Persona4Arena'', when [[spoiler:Labrys']] {{Shadow|Archetype}} reveals itself, it forcibly removes [[spoiler:Labrys']] human guise to reveal to everyone that [[spoiler:she is actually a {{robot|Girl}}]].
* In ''EchoNight Beyond'' [[spoiler:the young man]] is revealed to be a robotic copy of [[spoiler:Kenneth]], a man who was killed. Also, [[spoiler:Richard, the player character]] is a robotic copy of [[spoiler:the real Richard (aka. the space station chief) made by his ficanee (who was in love with the real Richard when he died)]].
* A quest in Rivet City, in the [[VideoGame/{{Fallout3}} Capital Wasteland]], has you looking for an escaped android with fake memories and a new face. As it turns out, [[spoiler:the android is the very first person you meet in the city, Chief Harkness.]]
* ''VideoGame/LastAlert'' has [[spoiler: [[MadScientist Dr.]] [[BigBad Garcia]].]]
* In ''VideoGame/MetalSlug 4'', [[spoiler: bionic versions of General Morden and Allen O'Neal are shown being produced, the latter being fought as a mini-boss in the final mission, ''Franchise/{{Terminator}}''-style.]]
* In ''Neo VideoGame/{{Contra}}'', [[spoiler: [[BigBad Master Contra]] is actually revealed to be a machine, and that [[TheManBehindTheMan the real Master Contra is actually Project C, the ultimate weapon made up of Bill Rizer's consciousness]].]]
* Subverted in ''VisualNovel/BionicHeart''. When Luke first meets [[ArtificialHuman Tanya]], she has had half her face blown off by the police pursuing her, revealing the mechanical parts underneath her skin.
* In ''VisualNovel/VirtuesLastReward'', it is at one point hinted that there may be a secret robot among the cast. It is eventually revealed that [[spoiler:Luna is, in fact, a GAULEM]].
** This trope also happens in one of the paths when [[spoiler:Sigma]]'s arm is cut and a white fluid comes out of it. By the ending of the path, it is revealed that [[spoiler:he has cybernetic arms, but the rest of him is human]] .

* [[spoiler:Asher]] from TheLeetWorld, whose eyes [[GlowingEyesOfDoom flash]] {{red|EyesTakeWarning}} after he receives new programming through the television.
* ''HowToKillAMockingBird:'' [[spoiler:Scout is actually a ROBOT GUY!]]
* PotterPuppetPals episode "Ron's Disease" combines one with a SuddenlySexuality for Dumbledore.
* At the end of the ''WebAnimation/NapsterBad'' short "Metallica Millionaire", the game show host [[Series/WhoWantsToBeAMillionaire Regis Philbin]] turns out to be a robot as [[Music/{{Metallica}} James Hetfield]] smashes him.

[[folder:Webcomics]]
* Parodied/inverted in [[http://dresdencodak.com/2009/05/11/42-essential-3rd-act-twists/ this]] [[NewFirstComics forgotten]] ''DresdenCodak'' strip.
* Similarly parodied/inverted in [[http://freefall.purrsia.com/zu/ffsim.gif this comic page]] from ''Webcomic/{{Freefall}}''.
* Inverted [[http://sluggy.com/daily.php?date=000527 in]] [[http://sluggy.com/daily.php?date=000528 these]] ''SluggyFreelance'' strips where [[spoiler:Oasis bleeds after being stabbed through the gut, revealing that she's ''not'' a robot like everyone thought. Whether she's human in the strictest sense of the word is still unknown, however]].
* Inverted again (maybe there's a pattern?) in this ''AntiheroForHire'' [[http://antiheroforhire.com/d/20070528.html strip]].
* Used with a goat and a hawk in [[http://drmcninja.com/page.php?pageNum=2&issue=17 this page]] of ''Webcomic/TheAdventuresOfDrMcNinja''. {{Lampshade}}d in the AltText: "I think my favorite way for a cyborg's mechanical innards to be revealed is by artillery fire to the face."
* From ''WebComic/AxeCop'' [[http://axecop.com/index.php/acepisodes/read/episode_5/ episode 5]]: "The evil flying book turned out to be a robot and it exploded."
* [[VideoGame/Left4Dead2 Coach]] if you believe [[http://www.vgcats.com/comics/?strip_id=289 this]] VGCats strip
* A rather odd case in ''Webcomic/CommanderKitty''. It's first revealed [[http://www.commanderkitty.com/2010/12/05/dont-wait-up/ through dialogue]] that [[BigBad Zenith]] is actually a RobotGirl, with the first visual indication not happening until later when [[http://www.commanderkitty.com/2011/07/12/well-theres-yer-problem/ we see her with a cable attatched to her chest]].

[[folder:Web Original]]
* In ''{{Morenatsu}}'', one non-canon bad ending on [[spoiler:Tatsuki's]] route reveals him to be [[spoiler: a robot created by Shigure. He kills both Tatsuki and Hiroyuki, the latter because he now knows this secret]].
* In ''RedVsBlue'', if Carolina didn't figure out [[spoiler:Tex was a robot when she was shot in the shoulder--complete with sparks--in season 9]], she certainly had to have figured it out when [[spoiler:Tex gets stabbed deeply in the back with no side effects in season 10]].
* ''{{Literature/Worm}}'' has Dragon, a Canadian woman widely lauded as the greatest [[GadgeteerGenius Tinker]] in the world, who deploys to each battle with a new set of high-tech battle armor. Her [[ADayInTheLimelight interlude]] reveals that she's actually a partially developed ArtificialIntelligence, severely crippled by the death of her creator while she was still in development.

[[folder:Western Animation]]
* In the Franchise/WallaceAndGromit short ''WesternAnimation/ACloseShave'', when Preston is put into the sheep-shearing device, sparks fly, and the RobotDog emerges stripped to the metal.
* Oliver, in the ''WesternAnimation/KimPossible'' episode "Grudge Match", is first pinned to a giant magnet, then has his face pulled off. He was being used as a [[TheBeard beard]] by a [[HotScientist supermodel-lookalike]] robotics expert.
** Eric in [[TheMovie The]] [[WesternAnimation/KimPossibleMovieSoTheDrama Movie]], [[spoiler:was acting as a human until he electrocuted Kim while she hugged him, though to be fair, this is more "sack of goo" than "robotic".]]
* [[spoiler:Sari Sumdac]] from ''WesternAnimation/TransformersAnimated'', ends up with a chunk of her elbow missing, with Cybertronian circuitry poking out. [[spoiler:This one was just as much a surprise to her as everyone else.]]
* Above quote is the titular ''Franchise/TeenageMutantNinjaTurtles'' first encounter with their most common MechaMooks in the [[WesternAnimation/TeenageMutantNinjaTurtles1987 first cartoon series]]. Despite Raphael actually stabbing one, Michelangelo's exclamation seems to imply they had been previously holding back.
** ''WesternAnimation/TurtlesForever'', the crossover between the first two TMNT cartoons, has a reveal when the 2003 Turtles learn the 1987 Foot Soldiers are robots.
-->'''2003 Leonardo''': Robots?
-->'''2003 Michelangelo''':''(enthusiastic)'' ''Exploding'' robots.
* Inverted in ''WesternAnimation/SouthPark'', in which Cartman's robot disguise (consisting of a couple of cardboard boxes) manages to fool everybody until he gives the game away by farting.
** Also played straight in the "Trapper Keeper" episode.
* Every slain enemy in ''WesternAnimation/SamuraiJack'' turns out to be a robot, regardless of how human they looked or behaved, if they were encountered in a cockfighting ring, or even if they appeared to be wild animals. Similarly, any limbs he chops off non-robotic characters will turn out to be cybernetic prostheses.
* In a few times in ''Franchise/ScoobyDoo'':
** Charlie in an episode of "Scooby-Doo, Where Are You?"
** The No-Face Zombie in the "No-Face Zombie Chase" episode of "The Scooby-Doo Show"
** The Ice Monster from the pilot eposide of "What's New, Scooby-Doo?"
** The Ghost Monster Trucks in the race episode of "What's New, Scooby-Doo?"
** The Ninjas in "Scooby-Doo And the Samurai Ghost"
** The Fright Hound from ''WesternAnimation/ScoobyDooMysteryIncorporated''. It was essentially a canine {{Expy}} of [[Franchise/{{Terminator}} the T-800]].
* An episode of ''Inch High Private Eye'' featured a mad dollmaker as the VillainOfTheWeek, who uses robot mannequins to rob department stores. When he's eventually caught, the heroes discover they only captured a decoy. He returns for a second run, with mechanical copies of the titular character and his boss, but this time, they catch him for real.
** As a matter of fact Creator/HannaBarbera loves this trope for some odd reason, taking it so far, that sometimes, the main villain of the episode turns out to be one. Nobody seems to question where the robot came from or who built it.
* PlayedForLaughs with a robotic duplicate of Leela in the first episode of the ''WesternAnimation/{{Futurama}}'' revival. Everybody except her realized that she was a robotic duplicate, until Nibbler bit a chunk off of her arm, revealing circuitry. She spent the rest of the day screaming. [[spoiler:Also done with a Fry duplicate later that episode.]]
** Also spoofed and then immediately inverted in the earlier episode "Insane in the Mainframe", where the trauma of being committed to a robot asylum eventually causes Fry to believe he is a robot. In the episode's conclusion, bank-robbing robot Roberto stabs Fry, but the knife hits a can of oil he put in his jacket pocket earlier, causing Roberto to believe Fry really is a robot. Moments later, Fry snaps out of it when he sees the blood coming from a cut on his arm.
** Yet another ''Futurama'' episode has Bender going on a fox hunt, only to be hit by sudden empathy when it's revealed the fox was in fact a robot. As were the hounds. And the horses. [[spoiler:And, at the end of the episode, the head hunter.]]
* In the ''WesternAnimation/{{Gargoyles}}'' episode "Leader of The Pack", Xanatos breaks The Pack out of jail. During an epic fight on board an oil tanker, [[EvilDetectingDog Bronx]] tears off half of his face, revealing that "Xanatos" is actually the robotic duplicate, Coyote. Of course, the whole point of the exercise was [[spoiler:to get Xanatos' girlfriend Fox a shot at early parole for her actions during the jailbreak at the start of the episode]].
* In ''WesternAnimation/{{Sealab 2021}}'' Quinn reveals in an episode that he is a robot. This isn't mentioned again afterwards and was thought to just be a wacky joke since there's NegativeContinuity. But then a later episode mentioned it again. I guess they don't really seem to care much.
* The ''WesternAnimation/TeenTitans'' episode "Masks" first introduces [[BigBad Slade's]] trademark {{mooks}}, who dress decidedly like ninjas. At the end of the first fight with them, though, Robin rips the mask off one of them, revealing the robotic circuitry beneath. Later episodes also had "Slade" being revealed as one of his android doubles, with the real Slade speaking through them from an unknown location. Averted with other MechaMooks later in the series--the robot soldiers that served Brother Blood and the Brain were clearly shown to be machines from their first appearances.
* ''WesternAnimation/ThePowerpuffGirls'' villain Roach Coach is revealed to be a sentient roach, in a MobileSuitHuman.
* In ''WesternAnimation/YoungJustice'' Professor T.O. Morrow is revealed to be a robot when Red Volcano kills him. The real Morrow is dying in hospital, having built a robot duplicate to carry on his work. It subverts ComicBookTime in the process, as Morrow had been active since World War II without seeming to age.
* In ''WesternAnimation/SuperRobotMonkeyTeamHyperforceGo'', we have Jinmay. Funny thing is, she was just as surprised as we were.
