->''"Kojack is pretty much just evil Jack, and evil makes everything better!"''
-->-- '''[[LargeHamAnnouncer Kreese]]''', ''VideoGame/MadWorld''

The Evil Knockoff is what happens when the BigBad decides that he could finally beat that frustratingly tenacious hero if only he had... ''his own, personal, mindlessly loyal copy of the hero!'' This is based on the theory that there's something about the hero personally that makes them unbeatable. (Big Bads do tend to obsess about this stuff.)

For a character to be an EvilKnockoff, it must be a copy created at least partly for the purpose of defeating TheHero in combat, on the principle of fighting fire with fire.

In the least justified cases, the Big Bad produces [[RobotMe an obviously mechanical copy]] with superficial visual resemblance to TheHero but little functional similarity; for example, a robot "copy" of a human ninja could rely on hidden machine guns and rocket launchers. This prompts the question of just what talismanic property of the hero's appearance is actually getting copied into "Mecha-Hero." The reason why is some absurd and never clearly articulated theory that "nothing can be as strong as the hero but the hero- ''or something that kinda looks like him!''"

In more justified cases, the Big Bad knows strength when he sees it, and so makes sure the copy shares some basic capabilities or power source with the hero, or is an actual clone. If TheHero is ''already'' mechanical or otherwise manufactured (i.e. an engineered SuperSoldier), the copy will usually be based on that hero's original blueprints or other stolen underlying technology, be reasonably close in appearance and capabilities, and fight in a nearly identical fashion, resulting in a battle of wits and spirit instead of the more usual [[AnAesop Aesop]] that [[CloningBlues copies are never as good as the original]].

Some villains don't stop with just one Evil Knockoff, and SendInTheClones to produce a small army of Evil Knockoffs. Thanks to ConservationOfNinjutsu, these clones are usually not quite as good as the original, but make up for that via sheer numbers.

Often a form of LaserGuidedTykebomb. SisterTrope to EvilTwin (evil identical twin), EvilCounterpart (evil character with similar abilities and/or history who took another path), and CriminalDoppelganger (evil IdenticalStranger). Related to MirrorBoss and SixthRangerTraitor. Often, whole teams being cloned results in ThePsychoRangers. If the knockoff turns out to be the manifestation of the hero's inherent evil side, it's an EnemyWithout. Contrast PsychoPrototype, where the hero is the "Good Knockoff".

!!Examples

[[foldercontrol]]

[[folder:Anime]]
* The Corpse Corps from ''Anime/BloodPlus'' are clones of the Schiff. Well, clones of Moses, at least. Interesting in that the schiff themselves are vampire "knockoffs" who've become a PhlebotinumRebel SecretProjectRefugeeFamily.
* The Cloneblades from the ''Anime/{{Witchblade}}'' anime are an odd case, being clones of an artifact instead of a character.
** Casual variant, as both Cloneblades and Excons/iWeapons are [[BlackBox fruits of research]] which began when Dohji Industries and NSWF were ''allies'' and ended before they came to blows (i.e. catastrophe), so neither is created ''specifically'' for battle with each other or original. Also, Cloneblades are more imitation than copy, never showing any signs of being [semi]sentient/self-willed (unlike Witchblade). NSWF checked whether would-be wielder is physically and mentally ''ready'' for Cloneblades, but measured ''compatibility'' for Witchblade.
* ''{{Guyver}}'' has Guyver II, who should have beaten the hero.. and would have had his control metal not been shattered from the outset. In fact, it's so unrealistic that Sho beat him so early that the most recent anime changed it around, making Guyver II the "boss" for the Cronos Japan opening arc. (This was, by the way, done with Yoshiki Takaya's appoval.)
** There's also the ''female'' Guyver II from the ''Guyver: Out of Control'' OVA. She's the final opponent Sho faced and she pretty well beats the shit out of Sho from nearly start to finish. Only the Control Metal picking then and there to go haywire from extended use saved him from being either killed or enslaved by Kronos.
* ''GetterRobo Armageddon (The Last Day Of The World)'' had Dr. Saotome unleash a horde of mass-produced copies of Getter Robo G, from the second season of the original series.
** Not only that, Saotome and two other villains actually pilot a much more powerful Getter G near the end of the series and duel the heroes in a roughly evenly-matched battle.
* The Eva Series in ''[[Anime/NeonGenesisEvangelion End of Evangelion]]'' are mass produced copies of the Evas. Unusually for this trope, but typical for ''Evangelion'' style {{deconstruction}}, these copies are superior to the protagonists' units. They have infinite sources of power, flight ''and'' copies of the ArtifactOfDoom. Their opponent is Unit 02 armed with battery power, a combat knife, and a really angry German. [[spoiler:The original loses.]]
** However, all these copies are still inferior to Eva-01 the Super Prototype equipped with an even better "infinite" energy source, the Original Lance of Longinus, superior Flight Capability, and a person born to Pilot Eva.[[spoiler: Of course, he doesn't even fight at all after having yet ANOTHER Mental Breakdown upon seeing Asuka and Eva-02's remains, so he and the Audience spend the rest of the Movie being Mindraped.]]
* In ''{{Demonbane}}'', Doctor West created a knockoff copy of the titular robot, with all its magic... except Lemuria Impact.
* Towards the end of the first series of ''{{Vandread}}'', the Harvesters produced copies of the Vandreads; after the first set of copies were destroyed, the mass-produced later versions [[ConservationOfNinjutsu didn't seem much of a threat]] in the Second Stage. The EvilKnockoff of the CoolShip Nirvana in the Second Stage, however, unexpectedly turned out to be a [[spoiler:TransformingMecha]] that was in fact ''stronger'' than the original. (The copy of it shown at the final battle though was [[VillainDecay much weaker, though]])
* In ''{{Gunnm}}'', [[spoiler: Tiphares/Zalem eventually creates the AR series, exact copies of Alita/Galley's cybernetic body complete with robotic chips for brains and her Panzer Kunst fighting style. Most of them get killed off, but three of them go on to get their own character development, in an attempt to become individual.]]
* Barasuishou in ''RozenMaiden'' was specifically created to defeat the real Rozen Maidens by Enju, the jealous apprentice of the maker of the original dolls. He eventually succeeds. [[KarmicDeath Well, sort of]].
* One episode of the original ''BubblegumCrisis'' OVA had Boomers dressed up like the Knight Sabers. Very powerful Boomers whose true forms take up at least 50% more volume than their disguises. (Standard fare for Boomers; at least they're consistent.)
* The Dark Bring "Decalogue" from ''RaveMaster'' is an EvilKnockoff of Haru's Ten Commandment's sword, with ten forms that match the forms of Haru's sword [[spoiler: except for the last one]].
* Amiba from ''FistOfTheNorthStar'', the second Hokuto Shinken pretender in the story, never actually trained in the style, but instead uses a variation he developed through pressure point experiments, which he dubs the "Amiba-style Hokuto Shinken". Needless to say, Kenshiro was not impressed.
* In ''Manga/{{Naruto}}: Shippuden'', Team Guy has to defeat copies of themselves in order to break a seal on a cave entrance. They are exact copies of the strengths and techniques of each team member. In true Team Guy style, [[spoiler: the copies are defeated because the originals become stronger than they were when they started the fight]].
* In the 2001 ''{{Cyborg 009}}'', Albert Heinrich/Cyborg 004 faces off against a robotic doppleganger. Having been manufactured ''after'' the [[PhlebotinumRebel cyborgs escaped]], it's significantly stronger than him, resulting in [[spoiler: a brutal NoHoldsBarredBeatdown until he finally does something the robot doesn't expect: save a bird's nest rather than try and avoid its attacks.]]
* Afro-Droid from ''Anime/AfroSamurai'' was directly copied from all of Afro's skills, moves, and knowledge, but by virtue of being a robot, was faster and stronger. Afro could only beat him by using moves [[DontThinkFeel that surprised himself]] and Ninja-Ninja, his companion [[spoiler: and possible sub-conscience]]. After the initial defeat, Afro-Droid came back with some new abilities hidden under the skin-like covering of his body: lasers, missiles, machine guns, flight, and an ''[[DoesThisRemindYouOfAnything incredibly phallic]]'' and lampshaded front-mounted {{BFG}}.
* ''Manga/AstroBoy'' has an inordinately high number of them. The first was an unstable copy created by a one-off enemy known as the Bronze Republic to prevent him from retrieving a spaceship component they stole. Then there's the 1980s version of Atlas (and the 2003 version to a lesser extent, but oddly enough not the original). Honorable mention goes to Astroboy Mk. II, who never actually met the real one & isn't evil so much as a JerkAss.
* In ''{{Hellsing}}'', [[spoiler: all of Milennium's vampires are cheap knockoffs of Alucard. The only members of Milennium who aren't knockoffs, the Captain and Schrodinger, also end up being the only members of Milennium who have ever defeated Alucard.]]
* [[spoiler: Iron Kaiser]] to ''MazinkaiserSKL'', being said to be directly based on Mazinkaiser's design and having almost identical set of attacks.
* One of the [[MonsterOfTheWeek monsters of the week]] in ''GaoGaiGar'' absorbs a bunch of spare parts and becomes an evil version of the title mecha. [[CrowningMomentOfAwesome The battle ends with dueling]] [[FinishingMove Hell and Heavens]].
** In ''FINAL'', [[spoiler:a BrainwashedAndCrazy clone of Mamoru uses a copy of [=GaoGaiGar=] to fight Guy in the improved [=GaoFighGar=]. Ends similarly to the above, but it's a massive TearJerker instead.]]
* ''Manga/DragonBall'': In a broad sense: Dr. Gero creats the Androids (actually more like cyborgs) after he observes that [[ZergRush armies of]] {{Mooks}} are of very little use against Goku and resolves to create a single fighter of immense personal power rather than mass-produced military machinery. The culmination of his research is Cell, so named because he uses cells stolen from Goku and the other protagonists to [[PowerCopying mimic their abilities]].
* ''Anime/DragonBallGT'' has Hell Fighter 17, the machine mutant clone used to brainwash and fuse with the original [[{{Cyborg}} Android 17]]. Trouble is, the scientists that made this happen should've known [[spoiler:they couldn't trust each other or the resulting [[EvilIsNotAToy Super Android 17]] not to pull a [[AIIsACrapshoot double cross]]]].
* ''Anime/TurnAGundam'' has a strange reversal: according to [[AllThereInTheManual external sources]], [[spoiler:it was actually the Turn A that was reverse-engineered from the Turn X, in an attempt to copy its technology. The people who created the Turn A were terrified of the Turn X ever being used against them and wanted something that could put up a decent fight against it... making the Turn A a "Good Knockoff" of the Turn X. The two machines are shown to be dead even in combat capabilities, to the point that the series ends with them locked in an eternal stalemate, neither able to overpower the other.]]
* In ''GreatMazinger'', the Mikene are able to replicate and mass produce Great Mazinger itself and turned them loose on their foe. They usually show up in various ''VideoGame/SuperRobotWars'' installments when the original ''Great'' storyline is used.
* In ''Manga/{{Claymore}}'' it is revealed that [[spoiler:Youma and Claymrores are the Organizations attempts at recreating weapons equal tot he power of the ''Descendants of Dragons'' called the Asarakam.]]
* In the manga version of ''Manga/MaiOtome'', [[spoiler:BigBad Sergay summons villainous clones of the [[Manga/{{Mai-HiME}} HiME]] to fight against the Otome in his bid to TakeOverTheWorld. Their powers are equal to those of the originals, but their personalities are nearly polar opposites.]]
* In the ''Anime/YesPrettyCure5'' movie, BigBad Shadow creates mirror copies of the girls for the purpose of destroying them. Four of the five are killed by their own GoodCounterpart while the last dies in a HeroicSacrifice.
** Done again near the end of ''Anime/SmilePrettyCure'' when Joker creates the Bad End Precure. This time, however, none of the five are spared.
* Inverted and played straight simultaneously in ''Anime/IlSolePenetraLeIllusioni''. [[spoiler:The Elemental Tarot cards were created from their Daemonia twins, which unfortunately allows the Daemonia card to manifest an evil copy of the Elemental card's current user. The evil cards can only be destroyed by their good version making a HeroicSacrifice.]]
[[/folder]]

[[folder:Comic Books]]
* The infamous [[ComicBook/TheCloneSaga Clone Saga]] in ''Comicbook/{{Spider-Man}}''. This was taken to its limits in one issue, where it ended with dozens of Spider-Man clones attacking our heroes.
* ''TheFlash'' comics has Inertia, who was created to be the evil Thawne family member when Bart Allen (Impulse I/Kid Flash II) refused his heritage as a Thawne.
* In most ''Comicbook/{{Superman}}'' stories, SelfDemonstrating/{{Bizarro}} is a creation of LexLuthor, intended to defeat Supes. For his part, Superman has pretty much never considered Bizarro ''evil'' so much as incredibly misguided. This is across all incarnations, from the confused Superman clone to the backwards denizen of Bizarro World.
* In the ComicBook/{{Legion of Super-Heroes}} storyline ''The Great Darkness Saga'', the servants of [[spoiler: {{Darkseid}}]] are duplicates of [[spoiler: Lydea Mallor (ancestor of Legion member Shadow Lass), Superman, a Guardian of the Universe, and Darkseid's sons Orion and Kalibak.]]
** In the Postboot version of the same storyline, the same BigBad has cloned minions of [[spoiler:his son Orion, fellow New God Big Barda, and, Firestorm.]]
* The various comic versions of ''Comicbook/SonicTheHedgehog'' usually feature Metal Sonic at some point- recently in the Archie comics, a robot duplicate of Scourge, Sonic's MirrorUniverse counterpart was also created.
* ''SonicTheComic'' renamed the Metal Sonic "Metallix" to be more distinctive, and explained his different appearance in ''Sonic CD'' versus ''Sonic and Knuckles'' as being due to there being a whole army of them, the Brotherhood of Metallix. Naturally, what with AIIsACrapshoot, they ended up going rogue, usurping Robotnik and even attempting to erase him from history, they also created their own [[EvilKnockoff Evil Knockoffs]] of Porker and the Omni-Viewer creating the Porker Metallix and Pirate Omni-Viewer.
** After the failure of the Sonic Metallix Robotnik created the Metallix Mark 3 which was modelled after Knuckles unlike the Brotherhood of Metallix the Metallix Mark 3 was loyal.
* [[AiIsACrapshoot Evil robot]] ComicBook/{{Ultron}} from the MarvelUniverse frequently tried making evil knockoffs (of sorts) to limited success. Both the Vision and Jocasta's thought patterns were based off those of Comicbook/TheAvengers WonderMan and TheWasp respectively, but both also quickly turned against him and would go on the become Avengers themselves, making them more-or-less [[InvertedTrope good knockoffs]] of already good characters. Similarly, Alkhema was created with the thought patterns of Mockingbird and was arguably a successful EvilKnockoff as she was genuinely evil but ended up betraying him anyway. Even later on, Ultron planned to replace all organic life with evil knockoffs after he [[KillAllHumans killed them all]] (he failed, of course).
** It is also revealed that Ultron himself is a EvilKnockoff of [[spoiler: his creator, Hank Pym, who used his own thought patterns in Ultron's programming process]].
** And again, in ''{{Spider-Man}}'' #520, Hydra reveals four Avengers knockoffs, using special gear to simulate their powers: The Hammer, with his electricity-manipulating hammer, as a counterpart of [[TheMightyThor Thor]]; Karl, a man in powered armor styled after IronMan (who refuses to call himself by his assigned codename, Tactical Force); The Militant, basically a terrorist version of CaptainAmerica; and Bowman, a counterpart to the (then-deceased) {{Hawkeye}}.
* Match, the evil clone of ComicBook/{{Superboy}} in TheDCU.
** Superboy as well. Didn't work out.
* [[Characters/GLBlackLanternCorps The Black Lanterns]] in ''BlackestNight'' are evil (and in the cases of dead villains, ''eviler'') knockoffs of the dead people chosen by the Black Lantern rings. The rings reanimate the corpses and simulate any powers and weapons they had in life and a twisted version of their original personalities specifically meant to provoke a strong emotional response from people, enabling the Black Lanterns to rip out their emotion filled hearts.
* Not so much evil as unfriendly and impolite, but Obmoz in ''ComicBook/{{Zombo}}'' was created as a more powerful version of Zombo that would do as TheGovernment commanded.
* The many evil doppelgangers of [[MarvelUniverse Earth's greatest heroes]] in the [[InfinityGauntlet Infinity War]], created by the villainous Magus.
* The Titanium Man was a KGB agent who had a suit of armor modeled specifically on IronMan's specs (although inferior Soviet resources meant that the resulting armor ended up being more than eight feet tall). The Iron Monger was a later villain to do the same thing.
* ''Comicbook/TheBoys'' has one of the strangest examples of this trope. [[spoiler:Black Noir is the Homelander's evil clone, designed and tasked to kill him should the need arise. While they look completely alike, Black Noir constantly wears a completely covering black outfit to hide this, and never speaks in public. Because the Homelander behaves himself for too long, Black Noir steals his costume and commits atrocities in his name, making sure he will hear of these things. This turns the Homelander from a superpowered asshole to a monster, as he starts to doubt his sanity and morality. Because the sanction still refuses to come, both Black Noir and the Homelander snap, and the latter starts a war between the government and the supers, while the former finally decides to kill the latter.]] As one character puts it, "[he] turned into a psychopath by mistake".
* Played straight in a hilarious manner in a ''GrooTheWanderer'' story. The antagonist is a sorcerer who can conjure up any thing or being he can imagine (though they are very temporary). When facing Groo, he declares "The only thing that can defeat Groo... is ''Groo''!" and conjures up an exact copy. [[spoiler: Who directly proceeds to cutting of the sorcerer's head by accident and then disappearing.]]
* This was M. Bison's evil plan in Malibu's ''[[ComicBook/MalibuComicsStreetFighter Street Fighter]]''.
* In issues 3 and 5 of ''[[ComicBook/JusticeLeagueOfAmerica2013 Justice League of America (2013)]], The JLA fights robot doubles of, not themselves, but the [[JusticeLeagueOfAmerica Justice League]] built by [[RobotMaster Professor Ivo]].
* The award-winning "Manhunter" arc (the Paul Kirk version that ran in early 1970's ''Detective Comics'') had clones of Paul as the Council's security forces. A variant in that Paul was initially head of security and they were created to ''help'' him, but after he found out what the Council was up to, they did wind up on opposite sides.
* In ''ComicBook/UltimateXMen'', the Weapon X program looked for a mutant with a similar HealingFactor to Wolverine's after Wolvie went AWOL in hopes of recreating the adamantium-bonding process, and found Sabretooth.[[note]]The sequence of events was rather different in the 616 universe.[[/note]] {{Lampshaded}} by Wolverine:
--> ''''Four'' claws? Well, ''[[SarcasmMode that'll]]'' [[SarcasmMode keep people from seeing you as a made-in-Hong-Kong version of me.]]''

[[folder:Fan Fiction]]
* In ''Fanfic/PerfectionIsOverrated'', the BigBad, The Usurper, is trying to take over the world with the help of the [[ParodySue SUEs]], but they repeatedly lose against [[MaiHime the Himes]]. In response, for his last stand against the heroes, he deploys the final two [=SUEs=] as references to the CopyCatSue archetype- Makoto Kagami, who can take the form of any canon character and chooses Mai, and [[SignificantAnagram Suzuka Harushiro]] who wields Haruka's power from the manga. Natsuki tells him he's a hypocrite for thinking the [=SUEs=] are superior when he's using ones who imitate the Himes' powers, and Makoto and Suzuka fall at the hands of the Himes.
* Examples from [[Fanfic/Swing123AndGarfieldodiesCalvinverse the Calvinverse]]:
** Retro and Rupert produce an evil Calvin in ''Fanfic/RetroChill'' in order to ruin the real one's reputation, which would weaken the Earth's defenses and allow them to TakeOverTheWorld.
** [[spoiler:The monotone clones]] from the two-part ''Fanfic/CalvinAndHobbesTheSeries'' episode "Electronic Invasion".
** In ''Fanfic/ThePezDispenserAndTheReignOfTerror'', the duplicate creates a robotic knockoff of Socrates with WolverineClaws.
* [[http://kleinerkiller.deviantart.com/gallery/41037509 Yognapped]] has [[spoiler: Xephos]], the clone made from [[spoiler: Lewis]]'s blood. He's a sadistic BloodKnight who, on his very first outing, [[spoiler: [[TheEndOfTheWorldAsWeKnowIt reduces the population of Minecraftia by the thousands]] and pushes the world into an AfterTheEnd state]].
** And now, [[spoiler: [[OhCrap there are four more clones running around.]]]]
[[/folder]]

[[folder:Film]]
* De Nomolos' evil plot in ''BillAndTedsBogusJourney'' involved a pair of robot Bill and Teds assassinating and then replacing the originals. This also counts as an Inversion after Bill asks "How do you defeat a pair of evil robot usses?" [[spoiler:You build a pair of ''good'' robot "usses"! (Hilariously, these do not look human at all.)]]
** Station!
* [[HumongousMecha Mechagodzilla]] in ''Film/GodzillaVsMechagodzilla'' (1974), which was created by [[AlienInvasion the Simians]].
** [[InvertedTrope Inverted]] in the Heisei continuity's ''Film/GodzillaVsMechagodzillaII'' (1993) and the Millenium continuity's ''Film/GodzillaAgainstMechagodzilla'' (2002) and ''Film/GodzillaTokyoSOS'' (2003), where Godzilla is the antagonist ([[GreyAndGrayMorality kind of]]) and Mechagodzilla is built by the humans to defeat him.
* An early example is the 1920's film ''Film/{{Metropolis}}''. In the film, slaves which toil to keep a city running find hope in the form of a woman called Maria, who leads them in rebellion. To counter this, the leaders of the city above create a robotic copy of Maria to take her place.
* Slightly different in ''Film/TheLeagueOfExtraordinaryGentlemen''. The BigBad only gathers the League so he can get samples of their powers, create multiple {{Evil Knockoff}}s, and sell them to the highest bidder - "an army of Hydes, invisible spies, vampire assassins" - together with Nemo's supertechnology.
* Nuclear Man is the Evil Knockoff of Superman in ''Film/SupermanIVTheQuestForPeace''.
* All of the major villains Film/IronMan has fought have been knockoffs of Tony Stark's own designs. The Iron Monger was directly based off the Mk I, the "Hammeroids" were designed to compete, and Whiplash designed his tech to beat Stark at his own game.
* Before the heroes confront Nicola in ''Film/{{Bunraku}}'', they each have to face off against an evil counterpart.
[[/folder]]

[[folder:Gamebooks]]
* In the ''Literature/LoneWolf'' series, Lone Wolf faces an EvilKnockoff of himself called Wolf's Bane.
[[/folder]]

[[folder:Literature]]
* The StarWarsExpandedUniverse, specifically Literature/TheThrawnTrilogy, has [[MyNaymeIs Luuke]] Skywalker, an evil clone of Luke made from the hand he lost at Cloud City and wielding the same lightsaber. He was indeed mindless, and designed that way, as an extension of his master's will. Also, one of the main villains of this arc also proved to be a clone of a character we'd meet much later in [[OutboundFlight a novel]] set during the prequel series, although ''he'' was very, ''[[InTheBlood very]]'' like the original. [[spoiler:Zahn originally wanted to make this character a clone of Obi-Wan Kenobi, but ExecutiveMeddling torpedoed it]].
* ''Literature/TheSilmarillion'' and ''Literature/TheLordOfTheRings'' has a variant example - Morgoth makes evil knockoffs of entire ''races'', the Orcs from the Elves, the Trolls from the Ents, the Balrogs and dragons from the Maia, and presumably the Ringwraith's flying steeds from the Eagles. This is part of the limitations of his power: "The Dark Lord [[CreativeSterility cannot make, he can only mock]]".
* Mark Vorkosigan of the ''VorkosiganSaga'' is a subversion.
[[/folder]]

[[folder: Live Action TV ]]
* ''Series/PowerRangersDinoThunder'' had an evil knockoff of the White Ranger after the original evil one did a HeelFaceTurn.
** And almost ''every Franchise/PowerRangers'' team has an episode in which the BigBad creates [[ThePsychoRangers bad Rangers]]. The Jungle Fury season did a variation on it, with the "Five Fingers of Poison," poisonous animal-based Monsters Of The Week, as an EvilCounterpart team rather than an EvilTwin team. They even got a morph phrase and poses. Later in the series, we have The Spirit Rangers, senior members of the Rangers' order, with original suits and attacks based on the masters' own animal spirits. Naturally, the masters are freed from {{Brainwashing}} and the baddies now have ''eight'' rangers to deal with.
** The [[Series/MightyMorphinPowerRangers original series]] did this most memorably in "Return of the Green Ranger" when White Ranger [[GodModeSue Tommy]] was cloned and the clone became the Green Ranger.
* Princess Ardala created several copies of the eponymous hero in ''BuckRogers''. One of them was to be sent to Earth to act as a spy; the others... were to be kept by Ardala [[LampshadedDoubleEntendre for her own private purposes]].
* In an episode of ''Series/TheATeam'' a villainous landowner hires some thugs to pretend to be the A-Team to terrorize his enemies, with a fake Hannibal, fake B.A., and a fake Face. It ends as well for him as you might imagine.
* [[Series/GetSmart KAOS]] created Gropo the robot to destroy Hymie (who was created by KAOS in the first place, but changed sides).
* In ''{{Primeval}}'', Helen Cutter creates a clone of Nick Cutter in order to infiltrate the ARC. The real Nick almost gets his evil clone twin to turn, telling him he has free will. [[spoiler: He fails. The clone however, whispers "Save yourself!" just as he sets off the bomb intended to destroy the ARC]]
* Kreel creates two copies of Will in ''Series/TheLegendOfWilliamTell''. One dresses up in a cloak and kills people to sully his name, and later [[LukeIAmYourFather pretends to be his long lost brother.]] The other kidnaps Vara and nearly kills the team before Will manages to straighten things out.
* In ''Series/{{Beetleborgs}}'' the Shadowborg was an evil Beetleborg reverse-engineered from the Blue Stinger Borg's armor specifically created to destroy the heroes. The good guys had to create a ''good'' knockoff of Shadowborg, the White Blaster Beetleborg, to even the odds. Because of the rules governing the magic that created White Blaster, when Shadowborg was eventually defeated White Blaster's power vanished as well.
* Subverted in ''Series/JuukouBFighter'', the ''Franchise/MetalHeroes'' series which was where the original footage of ''Beetleborgs'' came from, by the original version of Shadowborg, Shadow/Black Beet. Originally created to defeat the B-Fighters by his master, he eventually starts to question his own existence and his loyalty starts to waver. Then, it is revealed that he is an actual [[CloningBlues clone]] of Takuya/Blue Beet and is eventually become obsessed with beating Takuya in order to prove his own existence and in order to gain immortality as he is dying due to being a short-lived clone who was only created to serve his purpose in defeating the B Fighters. He eventually ditch his master to fight for himself.
* One episode of the classic ''Series/HawaiiFiveO'' featured a criminal who put together a team of lookalikes of the Five-0 squad in order to con a businessman out of a large chunk of cash.
** The episode was also notable for showing what a ''MissionImpossible'' type operation would look like from the ''other'' side.
* In the ''Series/VRTroopers'' episode "Kaitlin Through the Looking Glass," Grimlord makes an evil duplicate of Kaitlin. The dupe eventually does a HeelFaceTurn, helps the heroes stop Grimlord, and then agrees to be reabsorbed into Kaitlin (it must be done or both will vanish.) The reabsorption process [[MiraculousMalfunction goes wonky]] though, giving Kaitlin the permanent extra superpower to [[MesACrowd split off Kaitlin Two at will.]]
* ''Series/DoctorWho'':
** The Daleks construct an android version of the Doctor in "The Chase".
** Parodied cleverly (with the help from a bit of TomatoSurprise) in the ''Short Trips and Sidesteps'' story "The Android Maker of Calderon IV", in which an android builder creates a completely perfect android duplicate of the Third Doctor as his life's work, as part of an incredibly convoluted villainous plot to get revenge on the Doctor and Sarah Jane. Then the real Doctor shows up with Sarah, [[TheNthDoctor but he's regenerated into the Fourth Doctor since then]], making the robot useless.
* In the ''Series/HerculesTheLegendaryJourneys'' episode "If I Had a Hammer...," Hephaestus brings a statue of Hercules to life. He has all of the strength and looks of Hercules, [[DumbMuscle but none of the brains]]. Subverted in that he's not really evil, but rather childish and easily manipulated by Discord, who was using him to frame the real Hercules for murder.

[[folder: Tabletop Games ]]
* In ''MagicTheGathering'', cards like Clone, Vesuvan Doppleganger, and The Mimeoplasm let you create this, though (because of rules regarding "legendary", or unique, cards), doing it to one of those caused both to die up until 2014, which tweaked it so that the only restriction on legendary creatures is that the same player can't control two copies of the same one. Also, the Scars of Mirrodin block went out of its way to make Phyrexian versions of old cards.
** Sakashima the Imposter is a (somewhat clunky) workaround to the Legend Rule, though he has the ability to impersonate multiple creatures (sequentially), and so is arguably not an example.
* In ''{{Monsterpocalypse}}'', the monsters from the faction Ubercorp International are robot duplicates of monsters from other factions.
* Near the end of the ''TabletopGame/{{Paranoia}}'' adventure "Send in the Clones", the [=PCs=] discover that their adversary Teela O'Malley has been cloned multiple times. They end up facing an entire army of Teelas.

* Sabata from ''VideoGame/{{Boktai}}'' was abducted at birth by [[BigBad Hel]], infused with Dark Matter, and raised as a "Dark Boy" with the intent purpose of killing Solar Children. [[spoiler:Turns out he's not such a bad guy, just a [[TheFatalist fatalist]] with some serious issues who [[HeelFaceTurn changes sides]] and becomes TheLancer quite quickly once he decides he ''wants'' to fight fate.]]
* The Chaotic Blade of Doom from ''VideoGame/AdventureQuestWorlds'' is a Chaos Knockoff to Necrotic Blade of Doom and the Necrotic Blade of Doom is evil to begin with.
* ''Franchise/SailorMoon'' has evil counterparts to the Inner senshi for basically every season/arc, the only group that fits as Evil Knockoffs is the Opposito Senshi from ''VideoGame/SailorMoonAnotherStory''. Each Opposito has a corresponding power to her counterpart (dark water for Nabu to combat Mercury, for example) and they even have a unified uniform design. Their mission is specifically to take the power of the Ginzuishou and defeat their counterparts. In fact, if you show up without Mars at one point in the game when confronted by her Knockoff, Marduk calls Mars a coward.
* Dr. Ivo Robotnik in ''Franchise/SonicTheHedgehog'' has created several robotic duplicates of Sonic, Metal Sonic from ''VideoGame/SonicTheHedgehogCD'' (pictured above is a scene from his arrival in the [[SonicTheHedgehogTheMovie animated movie]]) being the most famous. He's never used more than one at the same time, though - apparently Robotnik is GenreSavvy enough to know about ConservationOfNinjitsu.
** On the other hand, ''VideoGame/SonicHeroes'' implied that Metal Sonic had created an entire ''army'' of Shadow androids after usurping Eggman. When he took back his position, Eggman uses those Shadow androids in ''VideoGame/ShadowTheHedgehog'' for a couple of stages. [[TomatoInTheMirror He also convinced Shadow that he was an android as well]], and Shadow, due to his amnesia, even accepted it in two of the endings. [[spoiler: However, about seven to eight minutes into the final battle, Eggman admits to the Shadow you control that he had saved him from [[ContinuityNod his death in]] ''VideoGame/SonicAdventure2'' and is the same ultimate lifeform that his grandfather, Professor Gerald Robotnik, created 50 years ago.]]
** The boss of ''[[VideoGame/SonicAdvanceTrilogy Sonic Advance]]'''s Angel Island Zone at first appears to be Knuckles, except that his colors are somewhat off... Halfway through the fight, however, his fake skin peels away and he starts firing huge missiles out of his mouth, revealing him to actually be a robotic duplicate called Mecha Knuckles.
* [[BaldursGate Jon Irenicus]] makes copies of the party members with his magic the first time you fight him. They're not much of a threat as they lack the skills and equipment of the Party and can only attack normally.
* The Sloth Clones from ''{{Neopets}}''. Unique in that they're clones of ''the villain that created them.''
* The final stage of ''MetalSlug 3'' features a disturbing piece of Martian OrganicTechnology which is continuously pumping out clones of one of your captured comrades. Fortunately, each clone is just as much a OneHitPointWonder as you are (well, actually they have 4 hit points, but they drop so much Heavy Machine Gun ammo that it doesn't help them stay alive any longer). Once you free your comrade from the machine, it starts producing zombies of him/her instead (and these are [[DemonicSpiders much tougher]], and even have that nasty Blood Vomit attack).
** In ''Metal Slug 5'' the Ptolemaic Army uses Metal Slug tanks of their own. In fact, the first boss of the game is a ''[[BiggerIsBetter giant]]'' Metal Slug.
* Depending on how you play ''VideoGame/MegaManX 2'', you either fight Zero, or Zero dispatches a cheap knockoff clone of himself built by the X-Hunters.
* ''VideoGame/{{F-Zero}}'' has Blood Falcon, a clone of Captain Falcon by Black Shadow.
* ''GuiltyGear XX'' has Robo-Ky, a green-skinned robot copy of Ky Kiske.
* ''Franchise/MortalKombat'' has Mileena, a clone of Kitana created by Shang Tsung with Tarkatan DNA as a plus, making her one heck of a ButterFace.
** This is also the entire flavor of the MirrorMatch.
* ''VideoGame/MegaManZero'' [[spoiler:'''inverts''' this by making the Zero you play as the knockoff, but the memory's real...the original Zero body is the mindless, AxCrazy one.]]
** Hell, ''VideoGame/MegaManX'' himself got cloned before ''Zero 1'' and fought Zero to the death. And again in ''Zero 3''.
*** The twist being that Copy-X (the [[CaptainObvious aforementioned knockoff]]) was ''never'' intended by his creator to be evil in the first place.
** And the original EvilKnockoff of ''VideoGame/MegaManX'' is ''Zero.'' Bass is also this to ''VideoGame/MegaMan''.
** Prior to that, ''VideoGame/MegaMan'' has also been cloned at least twice, once into triplets. In ''[[MegaManPoweredUp Powered Up]]'', whatever character you play as also gets cloned.
** In ''VideoGame/MegaMan6'', you even play as the EvilKnockoff, according to ''MegaManMegamix''. This makes the ensuing MirrorMatch...interesting to say the least.
*** Keep in mind that Megamix isn't Canon game-wise. You still play as the real Mega Man (why else would you have Beat and Rush? Copy Mega wouldn't.)
** All the [[spoiler:copy chip generation reploids]] that appear in ''X8'' and ''VideoGame/MegaManXCommandMission'' are basically evil knockoffs of [[spoiler:''X7'' debutant [[YoungGun Axl]]]].
** RomHack ''VideoGame/Rockman4MinusInfinity'' has Snatchman, which stands on the ceiling. After beating it once, it [[PowerCopying steals four of your weapons with the help of Dr. Wily's Stealing System.]]
* This comes up a few times in ''VideoGame/{{Metroid}}''.
** In ''VideoGame/MetroidPrime'', the SpacePirates make several weapon designs to emulate Samus's Chozo Powersuit. They also attempted to copy the morph ball, only to have it ''break every bone in the test subject's body''. Needless to say, they moved on.
** Later in the ''Prime'' games, Dark Samus appears, after the eponymous creature stole Samus's Phazon Suit. It has Phazon-based versions of several of Samus's attacks from the first ''Prime'' game.
** The SA-X in ''VideoGame/MetroidFusion'' is a bunch of [[StarfishAliens X]] taking the form of Samus's suit; when they infected her, she had to [[BagOfSpilling lose most of her suit to be cured]], so the SA-X has the upper hand for most of the game.%% Please don't natter about whether the SA-X is or isn't a copy of Samus.
* Inverted by ''VideoGame/TalesOfTheAbyss'' in almost every way conceivable: [[spoiler:The BigBad decides he'd rather have TheChosenOne for himself, so he kidnaps and makes an inferior clone of said chosen one and sends the clone back as a stand in while grooming said chosen one into becoming his disciple. TheChosenOne turns out to be a bit smarter than the BigBad had intended and rebels against him... While the clone ends up surpassing both the original ''and'' the BigBad himself, to the original's annoyance and the BigBad's utter surprise.]]
* The Riku Replica in ''VideoGame/KingdomHeartsChainOfMemories'', though when you fight him in gameplay, he fits [[ThatOneBoss/KingdomHearts the other definition of "cheap"]].
** And in ''358/2 Days'' it seems that [[spoiler: Xion, an imperfect Replica of Sora, was a failed EvilKnockoff]]
*** Ooooh, that's a really ''complex'' one. [[spoiler: Roxas is important to the Organization, because he can use the Keyblade, meaning that unlike the entire rest of the Goddamn Organization, he can actually contribute to it's ultimate goal. But Roxas is kind of a wild card and the higher-ups don't like that, so Xion was created to siphon off Sora's memories from Roxas, and his ability to use the Keyblade, so that they could have someone they could control. So she's actually meant to be an EvilKnockoff of ''both'' of them, and no, that's not redundant]].
* In ''[[NicktoonsUnite Nicktoons: Attack of the Toybots]]'', [[TimCurry Calamitous]]' evil legion of LivingToys are backed up by robotic clones of WesternAnimation/SpongeBobSquarePants, WesternAnimation/DannyPhantom, his archnemesis [[WesternAnimation/JimmyNeutronBoyGenius Jimmy Neutron]], [[WesternAnimation/TheFairlyOddparents Timmy Turner]], and [[VideoGame/TakAndThePowerOfJuju Tak]] who, beyond looking like those heroes, have zilch to do with them in abilities. The proposed explanation for this is that these robots are built from Master Models, figurines holding data from characters around the multiverse that Calamitous kidnapped and then dumped back home and mindwiped to keep his secret plans, uhh, secret (Except that the first two were never seen captured at all during the storyline, though their previous clash two games ago might fill in for that.). And considering what Master Models you collect in game, we have to question what makes him consider that ''[[WesternAnimation/HeyArnold Arnold]] is as worthy as [[WesternAnimation/AvatarTheLastAirbender Aang]].''
* The BigBad in ''Dengeki Gakuen RPG: Cross of Venus'' sends out copies of various characters (none of which are of the playable characters) to act out his evil plans of CanonDefilement on the featured LightNovels (really). All of those fakers are bosses (in fact, it'd be easier to list which bosses are ''not'' clones) and while looking exactly like the genuine characters (except for the [[LightNovel/{{Toradora}} Minori]] and [[LightNovel/ACertainMagicalIndex Kanzaki]] clones, who both have villainous eyes), they are also [[PowerCreepPowerSeep weaker]] than them (except for the Minori clone again, considering what kind of story ''Toradora'' is in the first place) as one of them admits after defeat.
* In ''EndlessFrontier'', the [[spoiler: Einst]] create copies of Haken and Excellen, and later even produce versions of the Personal Troopers.
** Also, in ''VideoGame/SuperRobotWarsOriginalGeneration 2'', they made the Einst Eisen, based on Kyosuke's Alt Eisen.
* ''VideoGame/TeamFortress2'' features the Robot Team, a team comprised of evil, robotic counterparts of the Mercs.
* ''KnightsOfTheOldRepublic 2'' features the HK-50s, which are the evil(er) knockoffs of HK-47. And HK-47 was [[RoboticPsychopath pretty damn evil]] to start with.
** It has to be said that for all their bragging, they lack the original's subtlety (and that's saying something) - the first one keeps dropping his facade so much [[FridgeLogic you have to wonder]] how he managed to fool anyone long enough to do anything. Not to mention their combat skills are nowhere near the original's - after a bout of grandstanding, three of them are wiped out by T3-M4, a pintsized astromech droid. (Then again, T3 ''is'' that badass. Maybe they should've copied him instead.)
*** HK-47 himself is angry at these knockoffs. It's too bad the HK-50 factory never made it into the final game.
** FridgeBrilliance: It's rather like what GeorgeLucas has done to Star Wars in the last 15 years. This could actually be a subtle criticism...
* Shadow Mario in the Mario series, although [[spoiler: he is really Bowser Jr. in disguise.]]
** Also, in ''VideoGame/PaperMario'', the Duplighost enemies could transform into your allies, and at one point in the game [[spoiler: a mirror breaks, and it turns out that Mario and his allies' reflections were actually disguised enemies behind glass]].
*** Metal Mario from VideoGame/SuperSmashBros and VideoGame/MarioKart is also one.
* In ''RatchetAndClankSizeMatters'', the BigBad creates an army of clones of the main character. At first they're identical replicas, but later on you meet ones with heightened attributes. These include speed, strength, and carrying a huge flamethrower. [[spoiler:Because they're really tiny, the ones that aren't destroyed are sold as toys, or are kept to keep Qwark company.]]
** And in ''RatchetAndClankUpYourArsenal'', [[spoiler:Clank is replaced by his EvilCounterpart Clunk.]]
* [[{{Golem}} The golem Astaroth]]'s CharacterDevelopment in ''[[SoulSeries Soul Calibur]]'' from the third game onwards revolves around him discovering that he is just an EvilKnockoff of Rock the "White Giant". Astaroth dedicates himself to killing Rock so that he can be a truly unique being instead of just a cheap copy.
** Soul Calibur was created to be a ''[[InvertedTrope good]]'' knockoff of Soul Edge. However, since it was created using a piece of Soul Edge itself, it turned out to be just as bad in a different way in ''Soul Calibur IV''.
*** Not so much evil as [[WellIntentionedExtremist draconian]].
** Not only that, Astaroth gets his own twin, who is a bright eyed idealist clockwork golem who matches Astaroth's moves but doesn't have the slightest bit of resemblance to him in appearance. She is tasked with bringing Astaroth back.
* The Issue 17 update of ''VideoGame/CityOfHeroes'', titled "Dark Mirror", revolves around this trope, with various dopplegangers for players to fight, of varying origins.
* ''VideoGame/CrashBandicootTheWrathOfCortex'' has Cortex create a bigger, more violent version of Crash named, imaginatively, Crunch. [[LateArrivalSpoiler Then Crunch joins Crash's side at the end of the game.]]
* In ''VideoGame/{{Rayman}}'', there's Bad/''{{Dark|IsEvil}}'' Rayman, created by ''[[NamestheSame Mr. Dark]]''.
* Kojack in ''MadWorld'' is basically a copy of the player character Jack. It's not known how evil he is, he's just another participant in the BloodSport that is Deathwatch. Jack certainly [[AntiHero isn't]] IncorruptiblePurePureness either, it's pretty much just the announcers who say Kojack is an EvilKnockoff of Jack.
* ''DragonQuest'' gives us the [=FooHero=], [=FooFighter=], [=FooPriest=], and [=FooMage=], knockoffs of the [[JackOfAllTrades Hero]], [[MightyGlacier Warrior]], [[BlackAndWhiteMagic Priest, and Mage classes]].
* In the [[YouKeepUsingThatWord international]] [[NoExportForYou version]] of ''VideoGame/FinalFantasyX'', there are a handful of sidebosses called the Dark Aeons, which are {{PaletteSwap}}s of your original Aeons. They're also [[ThatOneBoss much harder.]]
** Played with at the end of the game proper. Yu Yevon [[DemonicPossession possesses]] each of the Aeons that you summon, transforming the into enemies identical to the aforementioned Dark Aeons (just not ''nearly'' as hard).
* The supervillain Deja Vu in ''FreedomForce'' can make evil duplicates out of anyone he wants, so he chooses to make a bunch out of Minuteman (a CaptainAmerica {{Expy}}). The knockoffs have the same powers but have GlowingEyesOfDoom.
* Dark Link has appeared sporadically throughout Franchise/TheLegendOfZelda. His most [[ThatOneBoss memorable appearance]] was probably in ''VideoGame/TheLegendOfZeldaOcarinaOfTime''. He usually has similar sword play abilities compared to the main character, but a lack of magic and various items.
* In ''VideoGame/KirbyAndTheAmazingMirror'', [[spoiler:Dark Mind captures Meta Knight and creates a copy of him called Dark Meta Knight who is sent to attack Kirby. Dark Meta Knight is disguised as the real one for most of the game until the true Meta Knight reveals that he is an imposter.]]
* ''VideoGame/KidIcarusUprising'' gives us Dark Pit, created when Pit shattered a soul-reflecting mirror (it breaking is why Dark Pit isn't a perfect copy). However, despite Pandora's wishes, he's definitely more of an AntiHero than a villain.
** Later in the game, the [[spoiler:Aurum invaders create copies of enemies from the Underworld Forces ''and'' the Forces of Nature.]]
* A notable ability of Chaos Sorcerer in DawnOfWar II in LastStand is to create demonic copies of his enemies - and sacrifice them to restore health if he needs to. Alternatively, he can trade these abilities for increased health and attack power as well as ability to heal himself by sacrificing energy.
* In ''VideoGame/{{Super Robot Wars Z}}2'', [[http://www.youtube.com/watch?v=I-A96vSQKvA Anti-Spiral pilots]] a PaletteSwap of the Gurren Lagann with Anti-Spiral Nia instead of the Grand Zamboa because Tengen Toppa wasn't in the game.
* The ''Citadel'' DLC of ''VideoGame/MassEffect3'' has [[spoiler:the clone of Commander Shepard, created by Cerberus during Project Lazarus for the purpose of spare parts but who was awakened by Agent Brooks for the purpose of providing the ultimate weapon for Cerberus. S/he serves as the BigBad of the DLC, attempting to kill Shepard in order to replace him/her. The clone even fights with the same abilities as Shepard]].
* There's Carla Radames, [[spoiler: the [[BigBad Big Bad]]]] of ''VideoGame/ResidentEvil6''. [[spoiler: She originally was a scientist working for Derek Simmons, and created the [[TheVirus C-Virus]]. However, after Ada Wong left him, Simmons became obsessed with having her back. Eventually, he decided to use the C-Virus to transform Carla in a perfect clone of Ada. It worked, or so he thought. While the cloning process was meant to replace Carla's memories with Ada's (albeit slightly altered to make her think she never left Simmons), it only managed to shut them away temporarily. When those memories returned (kind of, as she never really realised who she used to be, only that she was pissed off at Simmons), Carla began to plot Simmons' downfall. It nearly worked, but the part of her mind that remembered who she was made her contact Ada. When the two of them met, Carla injected herself with the C-Virus, making her mutated into a giant mess of grey goo, after which Ada killed her.]]
* The two bosses of Mission 7 in ''VideoGame/DoubleDragonNeon'' are [[DumbMuscle dumb]], Abobo-esque clones of Billy and Jimmy called "Bimmy and Jammy."
* In ''VideoGame/DiabloIII'', during the second phase of the final battle, you not only have to face [[spoiler:the Shadow of Diablo]], but also the Shadow Clones of your character that it creates from time to time, which may or may not use the same major moves as you do.
[[/folder]]

[[folder:Web Comics]]
* Parodied in ''Webcomic/{{Adventurers}}''. Khrima creates robot duplicates of all the heroes, and plans to kidnap the heroes and replace them with their doubles to fool each other, only to be informed of the holes in this plan: the duplicates only vaguely resemble the people they're replacing; he built a double of [[ExactlyWhatItSaysOnTheTin Evil Killer Death Spybot 5000]], who is ''already'' a robot and ''already'' on their side; if all the adventurers are replaced by robots then when the trap is sprung the robots will be turning on each other; and, if they're kidnapped, then of course there's no need to trick them anyway.
* In ''ItSucksToBeWeegie'', Luigi ends up running into the one guy that might possibly suck more than he does; Waluigi. HilarityEnsues.
* ''MSPaintMasterpieces'' had Copy VideoGame/MegaMan, made by Dr. Wily to stop Mega Man and pre-loaded with all of the Robot Masters weapons. A logical move on Wily's part since Mega Man is, y'know, ''a robot he helped build.'' And honestly, it would have actually killed Mega Man if it weren't for outside intervention.
* In ''Webcomic/SluggyFreelance'', Santa Clause creates Mecha-Easter Bunny to defeat Bun-bun. The only way he could be more evil than [[KillerRabbit Bun-bun]] is to [[TheTokyoFireball destroy Tokyo]], which he does before he even appears on-panel.
* In ''Webcomic/{{Sonichu}}'', Robotnik and Giovanni make ''two'' Evil Knockoffs of Sonichu - Black Sonichu (later renamed "Blake") and Metal Sonichu. Metal Sonichu is defeated in his first appearance and Blake is an annoyance to Sonichu and the Chaotic Combo until his hidden away HeelFaceTurn after getting a girlfriend.
* The concept is parodied in [[http://zebragirl.net/?date=2000-12-08 this]] ''ZebraGirl'' comic.
* In ''RustyAndCo'', the hipster vampire [[http://rustyandco.com/comic/level-6-52/ sets out to do this to Cube, by drawing out his evil side, and gets Madeline]]. ([[spoiler:[[http://rustyandco.com/comic/level-6-53/ Would have worked between if she had more evil to draw out.]]]])
* ''SonicTheComicOnline'' has the new Metallix built by Grimer called "Neo Metallix" it is based on Metal Sonic's Neo Metal Sonic form.
[[/folder]]

[[folder:Web Original]]
* ''WebVideo/AtopTheFourthWall'' has the mysterious Mechakara, who resembles Linkara with a robotic hand. His origins and motives are unknown and mostly he's just lurked in the background chuckling in a sinister fashion and occasionally making subtle attempts on Linkara's life [[spoiler: and re-killing the original Spoony.]] Linkara apparently doesn't even know he exists.
** [[spoiler: He does now, and Mechakara even got to give a [[YouBastard What the hell, viewers?]] for taking [[ReviewsAreTheGospel reviews as gospel.]] ]]
** He turns out be [[spoiler: an AlternateUniverse version of ''Pollo the RobotBuddy''. He's only using the Linkara guise (which could very well be his universe's Linkara's ''skin'') so that he can steal the Magic Gun, an EmpathicWeapon.]]
* As related to the above, ''WebVideo/TheSpoonyExperiment'' has implemented this recently. At the end of Spoony's ''FinalFantasyVIII'' review, he is attacked by Squall, who was hired by Dr. Insano, ALL of whom are [[ActingForTwo played by Noah Antwiler]]. At the end of this encounter, both Squall and Spoony are killed, and Linkara takes to reanimating Spoony through cloning. This Clone is now the main character of the Spoony Experiment. The Evil Knockoff comes in when a short while later, a Black Lantern ring falls into Linkara's hotel room while he's at the Chicago Comic Convention, and reanimates the soul of the Original Spoony One. This Black Lantern version fights Linkara briefly, is defeated, and joins Linkara in a single review. He is then promptly murdered by Mechakara and brought back as a Black Lantern again. Then, in the ''Final Fantasy X'' review, before the review truly begins, the Original Spoony bursts in on Clone Spoony, explaining that he came back to life as Spoony the White, and came to kill the clone to get his show back. Upon finding out that Clone Spoony was going to review Final Fantasy X, however, Spoony the White shot himself with the gun intended to kill the Clone. He then promptly returns as a Black Lantern Spoony, again. Given the convolution of this plot, it's hard to say if he's really the original, an Evil Knockoff, or if this is reversed from the get go.

[[folder:Western Animation]]
* ''WesternAnimation/KimPossible'' once had Drakken create a small army of feral Kim "clones." This plan failed, spectacularly, but at least he learned an important lesson: [[SpoofAesop "No clones."]]
* Utonium's college roommate did this in a [[TearJerker sad]], disturbing episode of ''WesternAnimation/ThePowerpuffGirls''. The knockoffs failed because he cut back on the sugar in order to increase profits. Those girls then move on to [[HeelFaceTurn Destroy their creator]], in the only permament death in the series.
** Not to mention the Rowdyruff Boys, who were created to be copies of the Powerpuff girls with a twist: being boys (made from "snips and snails and puppy-dog tails"), and naturally, being more violent.
* The ''WesternAnimation/{{Futurama}}'' episode "I Dated a Robot" had an army of evil Lucy Liubots.
* The J-Team from ''WesternAnimation/JackieChanAdventures'' had [[ThePsychoRangers an identical team of evil knockoffs]], until they did a HeelFaceTurn at the end of the episode.
* In one "Teen Force" short on ''WesternAnimation/SpaceStars'', Uglor created an evil duplicate of Elektra.
* Evil Emperor Zurg decides to make a team of evil, cloned rangers in an episode of ''BuzzLightyearOfStarCommand''. Trouble is, he takes them from their cloning vats a bit early and ends up with a team of evil ''kid'' versions of team Lightyear. [[spoiler:At the end of the episode, Zurg tries again, but waits too long and gets a team of senior citizens.]]
* The episode of ''WesternAnimation/BigGuyAndRustyTheBoyRobot'' in which the Legion Ex Machina reproduces Big Guy from his original blueprints -- which is a plot point, since Big Guy's final design differed from those blueprints in some very important ways -- the blueprint-[[ChestBlaster secret weapon]] different from the finalized [[AcePilot secret weapon]].
** There's also an episode where Donovan manufactured a line of Rusty-clone toys. In a subversion, they were perfectly docile. Then the [[BigBadDuumvirate Legion Ex Machina]] got a hold on one of the clones, and used it to control ''all'' of the clones. So, Big Guy and Rusty had to deal with an entire ''army'' of Evil Knockoffs.
* In ''WesternAnimation/{{Gargoyles}}'', Xanatos decides first to build a small army of cheap robotic copies of Goliath, then a suit of PoweredArmor for himself that resembles Goliath's appearance, then has ordinary humans gene-spliced into knockoffs, and then just out-and-out clones him. None of these schemes work, and the clone plan [[GoneHorriblyRight backfires so spectacularly]] he never tries again.
** Though it's worth noting that having the red exo suit does allow Xanatos to almost hold his own against Goliath and other non-humans. Additionally, Thailog and Xanatos together probably could best the Manhattan Clan. Pity Thailog hates both his dads.
** Part of the problem is that Xanatos' knockoffs have a nasty habit of [[HeelFaceTurn turning good]]. Of the four gene-spliced humans, only one remains evil throughout the entire series. Of the six clones, only two choose to be evil.
* Metalhead, Slash, and Tokka (never seen without Rahzar) in ''Franchise/TeenageMutantNinjaTurtles''. Metalhead is an obviously robotic and non-ninja imitation; the other two are at least other mutant turtles.
* The idea is lampooned in an episode of ''ActionLeagueNow'', in which The Flesh is impersonated by [=RoboFlesh=], who is indistinguishable from The Flesh aside from metal bolts covering his entire body. No one notices the bolts, and the evil mayor almost wins.
* Dr. Claw once created an army of ''WesternAnimation/InspectorGadget'' clones. Another episode had a M.A.D. Agent create a crude robotic duplicate of Gadget to frame him for crimes. The spinoff series GadgetBoyAndHeather also had one episode where [[BigBad Spydra]] created a copy of Gadget Boy named Bad Gadget Boy. Even GadgetAndTheGadgetinis was not immune to this trope, having an evil clone of Gadget in one episode and a disguised M.A.D. Agent in another.
* Aku does this to the titular Jack in one episode of ''WesternAnimation/SamuraiJack''. In this case, the clone is a physical manifestation of Jack's rage.
--> '''Aku:''' Is there no fighting style that can defeat his ?! ... Yeeees... No fighting style ''can'' defeat his!
** He is then defeated. Awesomely. Seriously, you have to see this.
*** [[spoiler: [[SheatheYourSword It isn't in a fight.]]]]
* The Dark Lord Chuckles the Silly Piggy created a mechanical duplicate of Dave called Mecha-Dave in an episode of ''WesternAnimation/DaveTheBarbarian''.
* Brother Blood made a whole bunch of evil Cyborgs by memorizing the original's blueprints on ''WesternAnimation/TeenTitans''. The problem turned out to be that you can only copy so much- and the human bits were not part of that.
** Heck, Blood went so far as to copy Cyborg's blueprints ''on himself'', turning ''himself'' into an EvilKnockoff. With Cyborg's powers added on to his own original ones, [[FanNickname CyBlood]] was nearly invincible- pity he didn't count on the power of DeusExMachina...
* In the old ''WesternAnimation/TheLegendOfZelda'' episode "The Doppelganger", Ganon creates an EvilKnockoff of Zelda (complete with "evil"-color outfit). It has a couple of tells: it can't make the Triforce float, [[GlamourFailure it casts no reflection]], and it's kisses were "colder than [Link] expected". Also, being a magic monster, it was destroyed by the energy blast from Link's sword (which had been previously shown to just sting actual people).
* Vlad tried several times to clone WesternAnimation/DannyPhantom, including creating a younger DistaffCounterpart.
** The thing is, he ''succeeded'' in creating the perfect clone. All he needed was that one mid-morph to finalize it.
* In one episode of ''WesternAnimation/AladdinTheSeries'', a chaos elemental can't figure out how to defeat Aladdin, so he makes a Bad Aladdin to fight him, complete with Bad Genie. Luckily, Good Aladdin figures out that Bad Aladdin wouldn't have freed his genie, so stealing the lamp works.
* In the {{DCAU}}, Cadmus created a clone of ComicBook/{{Supergirl}} named Galatea. She wasn't very nice.
** Like in the comic books, the DCAU version of Bizarro was created as a genetic clone of Superman gone awry.
** In the finale of the Cadmus story arc, [[spoiler:the Brainiac/Luthor hybrid]] generates robotic Evil Knockoffs of the JusticeLeague. Or alternatively you could argue they're technically ''regular'' knockoffs of AlternateUniverse {{Evil Twin}}s, the Justice Lords.
*** TheFlash didn't have a Justice Lord counterpart, as their StartOfDarkness was their Flash's death; his robot had the appearance of [[Characters/TheFlash Professor Zoom]], his EvilCounterpart in the comics.
* In one of ''{{Doug}}'''s [[HerCodenameWasMarySue Quailman]] stories, Dr. Rubbersuit captures Quailman and splits him into his good and evil halves, planning to use the latter as a henchman. The evil Quailman escapes and proceeds to wreak havoc.
* The ''Franchise/MastersOfTheUniverse'' character "Faker" is an evil palette-swap of He-Man himself, with blue skin, red hair and orange armor. Depending on which version of canon you accept, he's either a malformed clone (the comic book), or a magical creation of Skeletor (the animated series).
* A ''WesternAnimation/SheRaPrincessOfPower'' episode featured a creature that, on the Horde's orders, copied She-Ra's strength and abilities but, fortunately, also copied her personality.
* Lawrence Limburger and Karbunkle once created evil copies of the ''WesternAnimation/BikerMiceFromMars''.
* In the ''WesternAnimation/PhineasAndFerb'' episode "Cheer Up, Candace", Doofenshmirtz created robotic duplicates of Perry the Platypus to fight fire with fire.
-->'''Doofenshmirtz:''' [[{{Dissimile}} And by 'fire', I mean 'Perry the Platypus',]] [[DepartmentOfRedundancyDepartment and by 'fire' I also mean 'Perry the Platypus']].
* ''WesternAnimation/TheRealGhostbusters'' actually managed to create their own evil knockoffs in "Citizen Ghost." Or, more accurately, Peter created them when he [[NiceJobBreakingItHero forgot to burn the old flightsuits]], which were still covered in Stay-Puft's entrails; a flaw in the new Containment Unit further energized the suits.
* After Optimus recovered the [[InfinityPlusOneSword Star Saber]] in ''WesternAnimation/TransformersPrime'', Megatron took drastic steps to create his own ''Dark'' Star Saber to counter it. The Dark Star Saber ''shattered'' the original. [[spoiler:The reforged Star Saber fares much better.]]
** Earlier, Silas' efforts over the series researching the Transformers culminated in the creation of Nemesis Prime, a remote-controlled version of Optimus Prime.
** He's not the first of 'em, either. Nemesis Prime also appears in ''Anime/TransformersArmada'' (eventually proves to be part of or a projection by Sideways), and one Japan-only comic series (he goes on to make a HeelFaceTurn and become an AntiHero, partnered with ''Anime/TransformersEnergon'' Arcee.) Also, ''Anime/TransformersRobotsInDisguise'' has Scourge, who started it all. Sadly, the name "Nemesis Prime" wouldn't be coined until ''Anime/TransformersArmada'' a year later, so the only evil ''television'' Optimus Prime repaint to be a character in his own right winds up named after a G1 Decepticon he doesn't much resemble instead of the cooler name that later iterations of the concept would carry. (IDW Nemesis Prime isn't an example, though. A previous Autobot leader named Nova Prime took on the name went he went evil. Nova's not created from or in the likeness of Optimus.)
** Nemesis Breaker in ''Anime/TransformersCybertron'' is based on Leobreaker, created from his dark thoughts by a Unicron-empowered Megatron. As Leobreaker can combine with Optimus, Nemesis Breaker can combine with Megatron. The TransformationSequence even has everything change ''in the opposite order'' from Leobreaker's transformation.
** Megatron did this a bunch with Dinobot in ''WesternAnimation/BeastWars''. Once he created an all-organic clone of Dinobot's raptor form, once he made a pack of unstable cyber-raptors, and finally he just out-and-out made Dinobot 2.
** The latter does make a HeelFaceTurn at the end, when the original Dinobot's memories come back after [[spoiler:Rampage's death]].
* In ''WesternAnimation/Ben10Omniverse'', the Nemetrix is a knockoff of the Omnitrix created by Dr. Psychobos, Azmuth's UnknownRival, using incomplete blueprints of the prototype Omnitrix [[spoiler:provided by Malware]]. The Nemetrix can transform its bearer into non-sapient alien beings that are the predators of Ben's aliens. [[EgomaniacHunter Khyber's]] [[RightHandAttackDog pet]] wears the Nemetrix since sapient minds can't handle transforming into savage non-sapient creatures.
* In ''WesternAnimation/SonicSatAM''. Robotnik had kidnapped Sally and replaced her with a robot double that was so convincing, it fooled almost everybody. Tails was the only one who realized something was off, and Sonic only began to catch as on as well after Tails had warned him. In the end, Sonic was able to trick Robotnik by switching Sally out with the very same robot.

* FrederickTheGreat went out of his way to recruit light forces once he realized how effective MariaTheresa's [[ProudWarriorRace Croats and Hussars]] were at raiding.
* During lengthy conflicts, its very common for one side to copy or incorporate the other's weapons technology, tactics and strategy. Sometimes it went as far as recruiting the people who are responsible for whatever you were copying. The results can be anything from a noticeable improvement, to a bad knockoff.
* An example of something not at all for the purpose of [[SpaceBattle fighting]] would be, at least from the perspective of TheUnitedStates, the ''[[http://en.wikipedia.org/wiki/Buran_(spacecraft) Buran]]'' spacecraft, the SovietUnion's knockoff of UsefulNotes/{{NASA}}'s Space Shuttle.
* Rome didn't have a war navy until the I Punic War. The Romans captured some Carthaginian ships early in the war, and since they were [[OlderThanTheyThink serially produced]], it was easy to replicate the process and churn out their own fleet to fight the enemy at sea. Combine that with Rome's own ingenuity for war machines in the form of the ''[[http://en.wikipedia.org/wiki/Corvus_%28boarding_device%29 corvus]]'' boarding device, and that's why soon there was not a Carthaginian fleet anymore.
