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 {{Phlebotinum}} 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 preserve of villains. Indeed since cloning's 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).

Expect all the usual CloningBlues to be turned UpToEleven, since the copy has to deal with a LossOfIdentity on two levels; both as a copy of someone else and from losing their original identity (if they can even remember it).

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), and SelfConstructedBeing (where any material can be used as well as focusing on the being in question).



* [[http://www.youtube.com/watch?v=y0Ixn_Y2bIo This]] GE SuperBowlSpecial commercial uses Agent Smith (see ''The Matrix'' below) as a visual metaphor for their medical assistance software's ability to be "everywhere".

[[folder:Anime and Manga]]
* ''Anime/{{Naruto}}'' features a method of bringing people back from the dead by turning still-living people into clones of them.
** Another technique transforms a person in a walking puppet of the controller and transforms the puppet body to match the master. These copies are only as strong as the amount of energy the controller transfers to them. When they are killed, the bodies revert to their true forms.

[[folder:Comic Books]]
* In ComicBook/TheTransformers (UK), when Straxus fails into transferring his mind into Megatron's body, he turns a hapless Decepticon technician into a "Megatron clone" to attempt the transfer again.
* ''ComicBook/SpiderMan'':
** The infamous ''Clone Saga'' has ComicBook/NormanOsborn creating a copy of Aunt May via a "genetically-altered actress" while keeping the real Aunt May captive as part of his AssPull-errific master plan.
** Previous to this, the original ''Clone Saga'' was retconned by way of The Jackal using a retrovirus to create his clones, not the virtual instant clones as originally portrayed. Once ''ComicBook/TheCloneSaga'' kicked off, that retcon was unceremoniously dismissed in an "ILied" reversal.
* The Convert, one of the ''ComicBook/JusticeLeague3000'''s main enemies, does this ''en masse'' as his primary ability. [[spoiler:It's also how the future versions of the Justice League was created.]]

[[folder:Fan Fiction]]
* 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.]]

* The 2010 horror movie ''Victim'' is about a DeadlyDoctor transforming a young man ([[spoiler:who murdered his daughter]]) into a copy of his dead daughter through plastic surgery and brainwashing.
* The Spanish thriller ''[[Film/LaPielQueHabito The Skin I Live In]]'' has a similar premise, although the doctor in question is using a MagicPlasticSurgery technique he invented to turn his victim into a copy of his dead wife.
* In ''Film/TheMatrixReloaded'' movie and [[Film/TheMatrixRevolutions onwards]], Agent Smith gains the ability to do this (in [[Film/TheMatrix the first movie]] he could only BodySurf people who were still plugged into the matrix, like all the other agents). [[spoiler: By the end of the third film, he's more or less assimilated everyone in the Matrix [[ZombieApocalypse into a copy of himself]]]].
* Blofeld attempts this at the start of ''Film/DiamondsAreForever''. Film/JamesBond [[MuggedForDisguise KOs a scientist on the project, steals his clothes]], and subverts the trope by drowning the would-be clone in mud.
* ''Film/The6thDay'' [[ZigZaggedTrope Zig Zags]] this to justify how fast they can clone people. They use this trope to clone people, but they use it on "blank" clones they started growing beforehand.

[[folder:Tabletop Games]]
* ''TabletopGame/DungeonsAndDragons'' third edition introduces the psionic power "Mind Seed" which, after a week-long incubation, turns the target into a mental duplicate of the psion (though eight levels lower than the psion when s/he infected the target).
** This power, in turn, is one of the tools the Dreaming Dark uses in ''{{Eberron}}''.
* [[http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=254133 Essence of the Wild]] from ''TabletopGame/MagicTheGathering'' operates this way, turning any other creature you cast or otherwise put into play into a copy of itself. Since they will then also have the copying ability...

* In ''Literature/{{Stardoc}}: Plague of Memory'' Cherijo's long-dead first love, Kao Torin, is sighted on the Hsktskt homeworld. [[spoiler:He turns out to be a genetically altered Hsktskt, created from DNA extracted from Kao's corpse which was [[BurialInSpace buried in space]] by Jorenian custom.]]
* In ''Literature/{{Beta}}'', clones are created by extracting the soul of the original person (the "First") out of his/her body, then implanting a computer chip with information into said body.
* The ''Literature/{{MARZENA}}'' Series lay down the concept that certain people with neurochemically similar brains can form empathic states and become a singular mind when mentally linked up using the Bremen Chip. Connecting two similar brains together can cause the less-dominant brain to become more dominant-like (although the full effects can take months to manifest). [[spoiler: This is what happens to Lauren when she connects to Marian's brain, fully maturing an Independent Psychological State allowing her brain to mimic Marian's brain activity, and thus break into Marian's brain-locked computer.]]

[[folder:Live Action Television]]
* Similarly to the Matrix example, The Master in ''Series/DoctorWho'' does this to [[spoiler: almost the entire human race]].
** In the BigFinish audio play ''Mission of the Viyrans'', Peri becomes the vector for a pathogen that painfully converts the entire populace of a planet, Doctor included, into clones of her.

* A willing version of the process is ''very'' common in VisualKei. Whether out of their admiration for other artists or out of wanting in on their success, this happens with some artists who take FollowTheLeader to an extreme and become, in effect, clones of other artists' personas and sometimes even scarily close to their actual selves. Some common artists that pick up a lot of this are [[Music/HidetoMatsumoto hide]] of Music/XJapan - to the point that hide clones and cosplayers are almost their own subculture within visual kei - Music/{{Kyo}} of Music/DirEnGrey - who was himself one of Music/{{Kuroyume}}'s Kiyoharu - and Atsushi Sakurai of Music/BuckTick.
** Music/{{Kisaki}} and Music/{{Kaoru}} are among the ''many'' artists who are famous for hide clone attempts, though both have somewhat moved on from that phase.
** Leoneil of Music/{{Vaniru}} is probably the most famous Atsushi Sakurai clone yet - to the point that it is widely rumored the two are father and son.

[[folder:Video Games]]
* In ''VideoGame/ResidentEvil6'' Simmons created a clone of [[spoiler: Ada Wong (who he was [[StalkerWithACrush a little obsessed with]])]] by testing out the C-Virus on [[spoiler: Carla Radames]]. When she got her memories back, she was [[TheStarscream not amused.]]
* The cloning pod in ''VideoGame/EvilGenius'' works by copying the Evil Genius's appearance onto one of the many [[WeHaveReserves disposable]] {{mooks}} in your employ. The purpose of this is to get the mook killed in order to make the World Powers believe your Evil Genius is dead and lower your heat level.
* In ''VideoGame/KingdomHearts3DDreamDropDistance'', it is revealed that Organization XIII was designed to [[spoiler: gather twelve Nobodies who could be subjected to this trope in order to serve as [[BodyBackupDrive vessels for Master Xehanort's heart]].]]
* In ''VideoGame/FinalFantasyVII'', [[spoiler:Cloud Strife]] turns out to be this kind of clone of Sephiroth (along with countless others who were implanted with Jenova's cells, but he's the only one who displays the SOLDIER powers Seph had). He is also one, to a lesser degree, of [[spoiler: his dead friend Zack, whose personality and memories he partly absorbed after the resident MadScientist messed up his head]].
* ''VideoGame/TheKingOfFighters'' utilizes this in K's story. He's still considered a clone of main hero Kyo despite only being injected with Kyo's genes and retaining his own appearance.
* ''Franchise/{{Halo}}'' reveals in ''Literature/TheForerunnerSaga'' that [[spoiler:the Didact from the ''VideoGame/{{Halo 3}}'' terminals]] was the result of [[spoiler:the Ur-Didact (the one from ''VideoGame/{{Halo 4}}'')]] imprinting his consciousness upon a younger Forerunner. Unusually for this trope, the original personality still maintains some influence (most notably in his ''much'' more friendly attitude towards humanity compared with the original), and the act itself is portrayed as a necessary one, with the [[spoiler:Didact]] imprint even promising his host that he'll return control when his mission is over, though by the time that happens, their personalities seem to have become irrecoverably merged.
* In ''VideoGame/MetalGearSolidVThePhantomPain'', [[spoiler:Venom Snake]] is this to [[spoiler:Big Boss]], achieved through plastic surgery and hypnosis.
* 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.

* In ''WebComic/TheAdventuresOfDrMcNinja'' [[spoiler: King Radical's]] plan turns out to be to do this on a massive scale (more specifically [[spoiler: converting people into the inhabitants of the Radical Lands, where he came from]]).
* ''Webcomic/SchlockMercenary'' introduced the "[=REDHack=]" technology in the "Random Access Memorabilia" arc; StateSec's plan to capture a BigDumbObject was to [[spoiler:overwrite the [[BrainUploading mind backups]] of the civilian research staff with the mind of one of their agents, also including instructions to physically convert each victim's body into a SuperSoldier when the [[TriggerPhrase activation signal]] was sent.]]
* 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.

* In ''WesternAnimation/BatmanBeyondReturnOfTheJoker'', [[spoiler: the Joker implants his DNA and consciousness into Tim Drake, causing him to turn into a copy of him many years later.]]
* In ''WesternAnimation/AvatarTheLastAirbender'', the Gaang are given a [[StepfordSmiler creepy]] guide called Joo Dee. 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.]]
* 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.
* ''WesternAnimation/PhineasAndFerb'': Dr. Doofenschmirtz's -Inator in "Night Of the Living Doof" has the power to turn anyone repulsive...and we see that it does this by turning people into zombie-like clones of Heinz himself that can turn people into more Doof-clones [[ViralTransformation upon contact]]. [[ZombieApocalypse Chaos ensues]].
