* In an episode of''Anime/Dorohedero'', Chota is forcefully transformed into Nikaido in order to fool En and Chidaruma. However, he does not become a mental clone of Nikaido, therefore he has to act like he is her.

* ''WesternAnimation/PhineasAndFerb'': Dr. Doofenshmirtz's -Inator in "Night of the Living Pharmacists" has the power to turn anyone repulsive...by turning people into zombie-like clones of Doof himself, which turn other people into Doof-clones [[ViralTransformation upon contact]]. [[ZombieApocalypse Chaos ensues]].

* [[AdorableAbomination Mr. Frundles]] in ''WesternAnimation/RickAndMorty'' is a living GreyGoo scenario: anything it bites grows a living, sentient Mr. Frundles face. When it bites Season 2 Jerry's ankle his ankle becomes Mr. Frundles and it gets control of just his leg, but when it bites him on the face his ''face'' changes and it takes over his entire body. [[TheEndOfTheWorldAsWeKnowIt The entire world is Mr. Frundles about 30 seconds later]].
* ''WesternAnimation/StarTrekLowerDecks'': "[[Recap/StarTrekLowerDecksS2E01StrangeEnergies Strange Energies]]": After accidentally developing godlike powers, Ransom transforms the Apergosian citizens' heads into copies of his own, but retaining their natural orange skin.

* In the ''Literature/{{Twilight}}'' fanfiction ''[[{{Fanfic/Luminosity}} Radiance]]'', Elspeth accidentally does this. She can use her powers to [[MindRape implant thousands of memories into a given person]]. [[spoiler: With a bit of makeup, it's not to hard to mislead them as to which set of memories are their own.]]

* A virus transforms many demons in ''VideoGame/Disgaea4APromiseUnforgotten'' into clones of [[GoldfishPoopGang Axel]], first just acting like him, but later sounding and looking like him. The protagonists do manage to turn everyone back.

* One artifact weapon in ''TabletopGame/{{Pathfinder}}'' is a cursed, intelligent longsword that transforms any user who is drawn into a contest of wills against it and falls into such a clone of the long-dead barbarian warlord who originally wielded it

** In ''VideoGame/FinalFantasyVII'', [[spoiler:Cloud Strife]] and all the turns out to be this kind of clone of Sephiroth (along with countless others who were implanted with Jenova's cells, with the amount they were injected with determining whether they just get a little power boost [[spoiler: like everybody in SOLDIER]], or end up crippled, insane, and vulnerable to having their body completely taken over by Sephiroth).

*** This is how [[spoiler:the Weapons' Oversoul]] works - it overwrites [[spoiler:the pilot's]] personality with that of the person whose combat data was chosen as the template, and reshapes their body into a more monstrous and bizarre version of that person. Over the course of the questline, the player has to contend with clones of [[spoiler:Nael van Darnus, Gaius van Baelsar (whose original, still-alive self is decided ''not'' amused) and Regula van Hydrus.]]

* ''VideoGame/BatmanArkhamKnight'': Four individuals (Johnny Charisma, Christina Bell, Albert King, and Henry Adams) are slowly transforming into clones of ComicBook/TheJoker due to being transfused with his Titan-infected blood, which Joker shipped out to hospitals prior to his death in ''[[VideoGame/BatmanArkhamCity Arkham City]]''. This leads to them developing Joker's traits, such as green hair, white skin, and his AxCrazy personality traits.
* This happens to [[spoiler: Alcatraz]] in ''[[VideoGame/{{Crysis}} Crysis 2]]'' who was given [[spoiler: Prophet's nanosuit as the two were dying. Through the game, the suit heals him, at the expense of turning him ''into'' Prophet]]. The effect has fully completed by the time of ''Crysis 3'', with no mention of who the current [[spoiler: Prophet]] used to be.

* One episode of ''WesternAnimation/ArchiesWeirdMysteries'' shows Veronica accidentally causing the populace of Riverdale to start gradually turning into duplicates of herself after making a misguided wish on a wish-granting artifact that everyone was more like her. By the time Veronica is able to reverse this, the whole town is filled with snobby teenage girls and even Archie and Betty are starting to not act like themselves.
* In ''WesternAnimation/AvatarTheLastAirbender'', the Gaang are given a [[StepfordSmiler creepy]] guide called Joo Dee when they visit the Earth Kingdom. When her veneer breaks, she's taken away and replaced by an eerily similar guide who answers to the same name and insists she's the same person. [[spoiler: It's revealed that the city in question has an entire [[NightmareFuel room]] full of "Joo Dee"s being brainwashed into similar guides. It's never made clear if they're based off someone, but it certainly fits the spirit of the trope.]]
* Albedo from ''WesternAnimation/Ben10AlienForce'' is a [[TheGreys Galvan]] who turned into a copy of Ben thanks to making his own Omnitrix copy and the original setting Ben's DNA as the default form. He also retains his original personality while playing TheMindIsAPlaythingOfTheBody completely straight, hating Ben because his body gives him irrational impulses, hormones, and chili fry cravings (that last one being his own quirk that [[NeverMyFault he’s choosing to blame]] on Ben).
* In an episode of ''WesternAnimation/FamilyGuy'' Peter gains the ability to transform anyone he touches into a clone of Robin Williams.
* In ''WesternAnimation/{{Jumanji}},'' the protagonists manage to drop [[GreatWhiteHunter Van Pelt]] into a bottomless pit. However, afterwards Peter slowly begins to look and act more like him. Eventually VP!Peter explains that there must ''always'' be a Van Pelt in the game--even if Alan kills VP!Peter, ''he'll'' just become Van Pelt instead. They eventually save Peter, at which point the old Van Pelt manages to climb out of the pit and goes back to hunting Alan.
* In ''WesternAnimation/MiraculousLadybug'', this is MonsterOfTheWeek Reflekta's primary ability. Fortunately for the victims, they keep their personalities and simply transform physically into her. Fortunately for her, they do not get her superhuman powers but are robbed of any they might have. [[spoiler: It also has a logical weakness; since her powers are based around turning people into her, it does nothing further to whomever it's already affecting, especially if they act as human shields or get their hands on other equipment.]]
* The ''WesternAnimation/MonsterFarm'' episode "A Pair of Jacks" had Count Cluckula drink a potion that turned him into a duplicate of Jack Haylee.

* In the ''WesternAnimation/RegularShow'' episode "[[Recap/RegularShowS02Ep11BensonBeGone Benson Be Gone]]", [[MeanBoss Benson]] is replaced by Susan, who proceeds to work the park workers harder than he ever did, which slowly starts to turn them into copies of her, though they keep their original faces and personalities.
* An episode of ''WesternAnimation/UglyAmericans'' featured a plague that was turning New Yorkers into clones of Larry King. Apparently the plague was a rare side effect caused by the original Larry King taking too many medications that interacted in an unexpected way.

* ''WebVideo/OutsideXbox'': In the [=OXventure=] episode "Sect Appeal" [[spoiler: this turns out to be the cultist's plan; rather than grow Egbert clones from scratch, they're going to inject townsfolk with a serum to transform them into them.]]

* In ''Webcomic/ElGoonishShive'' [[http://www.egscomics.com/index.php?id=1656 this starts to happen]] to most the guests at the party Nanase and Ellen go to.

* ''Franchise/WonderWoman'': Queen Atomia's "Proton Chamber" turns those of her victims that are forced into it and put through the chamber's process all into identical clones which are near mindlessly loyal to her and extra susceptible to her mental commands.

* In a story arc in the ''ComicBook/JusticeSocietyOfAmerica'' has the nanomachines that give Cyclone [[BlowYouAway her powers]] suffer a malfunction that makes them transmissible and convert other women into copies of her. She eventually works out the problem and reverts the victims, but not before someone she went to for help exploited the situation to try and copy her powers.

* Wiki/RPCAuthority: [[http://rpcauthority.wikidot.com/rpc-239 RPC-239]] can replace someone's consciousness with his own by coming into direct physical contact with them. The worst part is that there's no way to revert this, not even with amnestics.
* Wiki/SCPFoundation:

One of the problems with cloning is how slow and inefficient it is; you have all the difficulties of creating life, letting the clone mature, dealing with it diverging from the original, CloneDegeneration and so on. One simple way around this is to start off with some raw materials...namely, another person. This can range from using FunctionalMagic or AppliedPhlebotinum to transform someone physically and mentally or using more mundane means like MagicPlasticSurgery and {{Brainwashing}}. Either way, the unfortunate victim becomes the original's {{Doppelganger}}.

Since this [[DeathOfPersonality basically]] involves killing the person the clone's "made" from, this trope tends to be the province of villains. Indeed, since cloning has become possible in RealLife (and no longer automatically brings to mind a MadScientist), this is a good way for a writer to keep the act of cloning someone as ethically questionable. A villain who makes a habit of it might also be TheVirus (especially if the clones are able to transform people as well).

Compare and Contrast; {{Humanshifting}} (where someone has the ability to transform into another person), WeWillNotUseStageMakeupInTheFuture (when this is used where a simple disguise would have sufficed), BodySurf, (where there is always only one of the "surfer", barring accidents), GrandTheftMe (where someone takes over another person's body), TheVirus (which transforms the victim into a member of the Virus' type, rather than into a specific individual, although this distinction may be blurred if the Virus has a HiveMind), FaceStealer (who forcefully transforms themselves into the original rather than the other way around), SelfConstructedBeing (where any material can be used as well as focusing on the being in question), and KillAndReplace (where the killer transforms into or impersonates the victim).

* ''VideoGame/TheKingOfFighters'' utilizes this in K's story. He's still considered a clone of the main hero Kyo despite only being injected with Kyo's genes and retaining his own appearance.

* ''Literature/Angelmaker'': The true villain, Shem Shem Tsien, used surgery and brainwashing to turn the serial killer Vaughn Parry into a perfect replica of himself, allowing him to "survive" and continue his plans well past his death by old age. This pseudo-resurrection didn't help his preexisting god complex any. A number of "prototypes" with incomplete brainwashing are employed as part of his goon squad.

** [[http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=447196 Metamorphic Alteration.]] Interestingly, while all clone spells encourage copying the strongest creature on the battlefield, this spell also rewards turning an opponent's best creature [[BalefulPolymorph into a copy of the weakest creature]].

* ''ComicBook/TheTransformersMarvel'': In the UK comics, when Straxus fails into transferring his mind into Megatron's body, he turns a hapless Decepticon technician Archforce into a "Megatron clone" to attempt the transfer again.
