The ability to make several copies of oneself, normally maintaining control over all copies. Usually comes implicitly with the ability to recombine said copies.

This power can be very potent. One can be effectively immortal if at least one of you survives, one gets the ability to distract, surround and hinder your opponent and if all the duplicates work from a single mind it all occurs with perfect coordination. This power is an opportunity for writers to show off the creative combat techniques and imaginative [[MundaneUtility Mundane Utilities]].

There may or may not be some idea of a central self, one copy who is the "proper" version for whatever reason: you have to kill that one to kill them all at once, one gives all of the commands, etc. The other copies, conversely, rarely [[WhatMeasureIsANonHuman count as persons]] in and of themselves; see also CloningBlues. If they ''are'' counted as actual people, expect WhichMe.

Possible side-effects include LiteralSplitPersonality. May be used in a DoppelgangerAttack, a BreatherEpisode might go for MesACrowd. Not to be confused with IAmLegion. PowerPerversionPotential means this naturally leads to ScrewYourself.



[[folder:Anime and Manga]]
* ''{{Naruto}}'': There are various Ninjutsu that can do this, each using a different way, but the Kage Bunshin no Jutsu (Shadow Clone Technique) is the first to be introduced and arguably the most iconic one among them, not the least due to the protagonist tending to utterly ''spam'' it (first ever use resulted in around '''2000''' clones!) as part of his pre-TimeSkip combat strategy.
** After the time skip he can make absurd numbers if he needs to. At one point he makes one shadow clone for ''every leaf on a tree'' so that all of them can train on using a new technique at once. Thus he can reduce needed to learn it from years to days.
* ''Manga/DragonBall'' has the Multi-Form Technique, developed by Tenshinhan, which splits the user into four bodies ([[ConservationOfNinjutsu though each body is only 1/4 the strength of the original]]). Krillin, Piccolo and others utilize the technique or variations of it throughout the series.
* Nico Robin has acquired to do the ability to do this during the TimeSkip in ''OnePiece.''
* In ''Manga/FullmetalAlchemist'', [[spoiler:Father]] creates all the [[spoiler:homunculi]] from undesirable pieces of his own soul, although you wouldn't guess it because, with the exception of [[spoiler:Pride]], there isn't much family resemblance. He can also reabsorb them, but that's a very unpleasant process.
* In ''Manga/JoJosBizarreAdventure'' Part 7: Steel Ball Run, the arc's BigBad [[spoiler:[[PresidentEvil President]] Funny Valentine]] stand allows them to pull copies of themselves to fight and to remain effectively immortal (as all clones share the same memories) or of others to [[spoiler:''[[ExpendableClone blow]] [[NeverTheSelvesShallMeet them up]]'']]
* ''Manga/UchiNoMusumeNiTeODasuNa'': Clara can use her {{super speed}} to create physical copies of herself. The only time she's ever used it is during the ''"Amazing Eighth Wonder Vol.1"'', where she used her clones to [[spoiler: gangbang [[ParentalIncest her own mother]]]][[note]]Clara was possessed by an alien parasite at the time. Once the parasite was destroyed, she returned to normal and lost all memory of the event[[/note]].

* Jamie Madrox of the Comicbook/XMen, aka Multiple Man, in the MarvelUniverse. If he leaves his duplicates separated for too long, they start to [[LiteralSplitPersonality become more independent and develop their own personalities]]. Sadly making a MesACrowd plot difficult for too long but an EvilTwin incredibly easy.
* Franchise/TheDCU:
** Multiplex, who gets this power as well as superstrength.
** The "Silent Majority", a member of a throwaway team of American-themed super-powered government agents called the [[IncrediblyLamePun Force of July]]. His code-name came from a combination of his personality (laconic) and his powers.
** There's Centipede, a Canadian super-agent who tracks Nelson in ''[[Comicbook/DialHForHero Dial H]]''.
** Bizarro can do this, but only under the light of a blue sun. He used this ability to create his own versions of Superman's friends and enemies, [[OppositeSexClone including Lois Lane]]. This is how [[BizarroUniverse Bizarro World]] was populated.
* The Engineer from ''ComicBook/TheAuthority'' could do this, using nanotech to extrude copies of herself. Her main limitation was that she spread her consciousness throughout her duplicates and the more she created the harder it was for her to manage them all. It was never explicitly stated if she could have created autonomous duplicates.
* Loki has has this power since the first Avengers story, though he uses it more frequently in the movies.
* Machine Man from ''ComicBook/UltimateFF'', being made of Gah Lak Tus nanomachines, is able to duplicate himself.
* The astral drops from ''ComicBook/{{WITCH}}'' are perfect duplicates of the Guardians, only without powers. The problem is that there's not multiple astral drops that get summoned and dismissed, only one that is put in limbo when non active, so they start developing their own personalities and feelings... And only Hay Lin treats her drop as an actual person ([[WhatTheHellHero something they get called on]]).
* ''ComicBook/{{Shakara}}'': Phaze is an alien assassin who can summon an infinite amount of AlternateUniverse counterparts of herself.

[[folder:Films -- Live-Action]]
* Penny from ''Film/SkyHigh2005'', a film about a highschool for superheroes, uses her power to make herself into her own one-woman [[TheCheerleader Cheerleading team]] and GirlPosse.
* A cut scene from the script of ''Film/BruceAlmighty'' featured Bruce creating an army of himself to beat up some thugs.

[[folder:Live-action TV]]
* Eli from ''Series/{{Heroes}}'' who could only be defeated if you took out the "true" him.
* ''Series/{{Smallville}}'':
** Brainiac, being as he was a Terminator 2 like living liquid metal produced by a spaceship, could do this [[SuperpowerLottery on top of so many other things.]] Mostly used so he could be in several places at once to throw people off his scent while plotting.
** A season two MonsterOfTheWeek, Ian Randall, was much more limited: one extra person would climb out of his back and he used one to study [[MesACrowd in two places at one so he could achieve the best grades]] since when they recombined so would their memories.
* ''Series/{{Charmed}}'':
** In a Season 1 episode, Prue casts a spell on herself to create two extra copies of her after Phoebe has a vision of her being stabbed. The two clones are also a LiteralSplitPersonality, as one represents her neurotic, control-freak side, and the other her highly repressed sexual side. The real Prue is unaffected by the split and acts like normal.
** Prue develops the power of AstralProjection in Season 2, but it's treated more like SelfDuplication (her astral-body is still on our plane, corporeal and can be seen by others).
* Alisha from ''Series/AgentsOfSHIELD'' is an Inhuman who can create seemingly limitless copies of herself. Taking out the "real" Alisha will also take out the rest.
* Danton Black aka Multiplex is the villain of the week in the second episode of ''Series/TheFlash2014''. In this case, there is a single "controller", who must be taken down. During the climactic fight, Barry uses his SuperSpeed to locate the one Danton with beads of sweat on him from the exertion of controlling so many copies and slams him into a pillar, knocking out all the copies.

* A possible UrExample is the 1943 French short story ''Les Sabines'', by acclaimed writer Marcel Aymé. It deals with an ordinary French woman called Sabine who happens to have this gift ([[AWizardDidIt don't ask why]]), of the "a single mind controls all the bodies" variety. At first she only uses it to do all the housework at once, but, when she meets a charming stranger, she decides to permanently split herself; one of her bodies will remain by her husband's side while the other elopes with the fellow. And as she keeps meeting more potential lovers, she ends up spread thin with thousands of copies all over the world (and people are starting to notice that wherever they go the keep running into unexplained lookalike). Deciding to punish herself, she sends one more avatar to live a tough, rotten life in the slums. Eventually, a thug murders that double, causing all the Sabines to die together.
* In the ''Literature/WearingTheCape'' books, there are a variety of Redux-type superhumans. Examples include Platoon, who duplicates himself permanently on a regular basis (there are implied to be dozens of him), and the supervillain Flash Mob, who can make 20 or so temporary duplicates.
* In ''Literature/ColdDays'', [[spoiler: Sharkface]] has this power, and uses it during the battle for Demonreach.
* In ''Literature/TheCandyShopWar'', one of the effects of the Sands Of Time is to split the wearer into three selves. It should be noted, however, that anything that affects one of the selves affects all of them. If one is injured, they are all injured. If one is under the affects of a magic candy, they all are. At the end of the hour, the selves recombine at the closest safe location to the average of their positions.
* ''Literature/WeAreLegionWeAreBob'': The point of a Von Neumann probe is that it can make more of itself to spread across the galaxy. Bob hesitates before making his first batch, but soon has no choice but to go through with it. Each new clone has a slightly different part of the original Bob's personality emphasized, and chooses a new name for himself.
* In ''Literature/SuperPowereds'', Julia can create multiple copies of herself with a HiveMind. It's originally stated that all of her clones are equal, but then this is revealed to be false. There is an original. In fact, she frequently sends a clone to a party, while being the designated driver herself. This allows her to experience everything a clone does without her own body being affected by the negative consequences. She also claims to be a good Christian girl and a TechnicalVirgin, which doesn't stop her from using her doubles to have wild sex (including [[TwinThreesomeFantasy Twin Threesome Fantasies]], of course) with guys. This way, she can maintain that her own body has never been penetrated, while also having plenty of experience and enjoyment.
* ''Literature/TheMachineriesOfEmpire'' has the radiant force multiplier, a bomb that, for a time, creates kaleidoscope-like copies of anything in its area of effect. The heretics use it to get a drop on Cheris' forces in the first battle.


[[folder:Myth and Legend]]
* Korean folk hero Hong Gildong could do this by transforming straw dolls into doppelgangers of himself.
* Pan, from Greek mythology, had the ability to split into multiple "Panes", each with its own name. Three of them, Agreos, Nominos and Aegipan, are described as having their own unique appearances, personalities and abilities.

* The backstory for ''VideoGame/MadDaedalus'' briefly mentions Icarus, a clone of Daedalus that he created to serve as his assistant.

[[folder:Tabletop Games]]
* ''TabletopGame/{{Champions}}'' and ''TabletopGame/MutantsAndMasterminds'' have this as the Duplication power.
* In ''{{TabletopGame/DCHeroes}}'' this was the Split power.
* The Selesnya Conclave from ''TabletopGame/MagicTheGathering'' has cards that have an ability called Populate which makes copies of Creature Tokens on the playing field.
* In ''TabletopGame/EclipsePhase'', the ubiquity of BrainUploading technology means that anyone can copy their mind-state and download it into a secondary body. This process is known as 'forking'. People can generate several types of forks - alpha forks are full, one-to-one copies of the primary ego. Beta forks are 'pruned' copies of the ego, usually with reduced skillsets and substantial memory loss, and are often created to perform a specific task. Delta forks are the most rudimentary type of fork, more like generic AIs with a personality template than full beings. When a fork's task is complete, it is usually merged back into the primary ego. However, depending on how long it's been since the fork was generated and how much the two minds have diverged, reintegration may be more difficult or even impossible. Up to a day of separation is acceptable, but at a week or more, substantial mental damage becomes a risk. The legality and morality of forking is disputed within the setting, and varies depending on which polity the characters are in - under some governments, forks are considered property, not sentient beings in their own right, or vice versa. Forking is a taboo subject in many places.
* In ''TabletopGame/MageTheAwakening'', the highly advanced "Manifold Presence" spell creates multiple temporary copies of the spellcaster. They can also be made autonomous and can potentially operate anywhere in the world, while sharing their sensory input with the caster.

[[folder:Theme Parks]]
* Figment has this ability in ''Ride/JourneyIntoImagination'' at [[Ride/DisneyThemeParks Epcot]], with there being an entire scene of his own clones running around.

[[folder: Video Games]]
* Janus Cascade in ''VideoGame/WildArms3'' revealed his ability to make duplicate bodies of himself, in an attempt [[FakingTheDead to escape death by the protagonist party]]. Unfortunately for him, [[FinalDeath he perished for good shortly thereafter.]]
* Some of the [[spoiler:zombie ponies]] can do this in ''VideoGame/StoryOfTheBlanks''.
* Flandre Scarlet of the ''VideoGame/{{Touhou}}'' series can do this up to three times for her "Taboo - Four of a Kind" spell card attack. She does this as an improvement of the stock vampire "turn into a swarm of bats, then back into a person" ability.
** Her sister Remilia enhanced the power in the opposite way - never more than one humanoid body, but has no limit to the number of bats she can exist as and can change back from any single bat.
* Shimmerstorm in ''VideoGame/LegacyOfHeroes''.
* ''VideoGame/RingRunnerFlightOfTheSages'' has a [[SpaceMaster caster]] ability called the Forked Path Catalyst, which creates two other copies of the caster. [[StealthInSpace Rogues]] can create decoys, with physical presence that ranges from standard {{hologram}}s to HardLight.
* This is where ''VideoGame/MegaMan3'' boss Gemini Man gets his name. According to ''Super Adventure Rockman'', he can have up to four clones alongside the original.
* In ''VideoGame/PhantasyStarOnline2'', [[spoiler: Dark Falz Double does this to guard the Profound Darkness.]]
* Subverted in ''VideoGame/SuperMarioRPG'', Yaridovich is able to disguise into several identical Toads (sans the one pretending to be the elder. Whoever,his real form looks nothing like the Toad duplicates. Played straight into one of his special moves, being able to make an equally strong copy of himself with less HP.
* In ''{{VideoGame/Destiny}}'', Taken Psions can perform this, sometimes to the level of MesACrowd.
* In ''VideoGame/FireEmblemFates'', the Mechanist class has the ''[[http://fireemblem.wikia.com/wiki/Replicate Replicate]]'' skill that allows the user to create a copy of themself. A copy shares everything that the original has, including skills, current stats, current class, and inventory.
* [[MeaningfulName Impfinity]], one of the Zombie Heroes from ''VideoGame/PlantsVsZombiesHeroes'' is capable of creating several clones of himself via a device on his chest. His Signature Superpower "Triple Threat" spawns two Impfinity Clones in random lanes.

[[folder: Web Comics]]
* ''Webcomic/GrrlPower'': Harem has this power, on top of being a HiveMind with teleportation powers. Any potential problems with the duplication are averted; each different body has a "different personality," but it's just a facade on Harem's part. In her words, "There's no 'this one' or 'that one,' there's just ME." Having said that, she does personalize each different body with hairstyles, tattoos, piercings, and wardrobes for each copy. It also helps that she has incredible intelligence.
* ''Webcomic/{{Paranatural}}'': A "racist whale-frog" spirit that breaks into Max's house has this power. It can bring any reflection to life, and feeds by [[AutoCannibalism eating copies of itself]].
-->'''Max:''' Okay that's a little out of my comfort zone. Gonna call for some backup.\\
'''Alt Text:''' A pragmatic ghost hunter would be happy with this turn of events, as the number of foes has decreased.
* In ''Webcomic/{{Sombulus}}'', Tenge Kaedermos has the ability to split into several autonomous copies of himself at will, as well as recombine himself magically. There seems to be no core copy or hivemind, though it is indicated that [[http://sombulus.com/comic/621 a copy will share the same level of energy as the original]]. The Morphids are another group have this ability as well, and can flood an area with [[http://sombulus.com/comic/750 hundreds of copies]] in a zombie-like horde. (Though in their case, it does not appear to be voluntary.)

[[folder: Web Original]]
* Troika of the Literature/WhateleyUniverse can split into three identical people, while OMAG can split into at least six people but the duplicates don't seem to have the autonomy that Troika's dupes do.
* The ''{{Literature/Worm}}'' universe offers several examples:
** The supervillain Oni Lee is a teleporter that leaves short-lived duplicates behind every time he jaunts. He uses this to great effect when combined with duplicated weaponry such as handguns or grenades.
** The superhero Prism can split into three copies and remerge into any of the three to gain enhanced strength, speed, and durability.
** Spree, a member of the villain team known as The Teeth, can spam vast hordes of duplicates ... that get dumber and dumber every second they're [="=]alive[="=].
** Cape-turned-mercenary Satyrical has the ability to produce flesh clones that can shapeshift to look like whoever he wants them to.
* Sebastian from ''WebVideo/ThePlatoonOfPowerSquadron'' can multiply herself. She mostly uses her power to get off work and to have someone to play video games with. Unfortunately, after a certain number of copies they get a little unstable and less like herself. [[spoiler:One of them even left to move in with her boyfriend due to constantly being treated like she's just a clone.]]
* Manson Haight, a small-time paragang member from ''[[WebOriginal/AcademyOfSuperheroes ASH]]'', has the power to make one duplicate every day.
* Flynt Coal from ''WebAnimation/{{RWBY}}'' can create four copies of himself, typically to amplify his trumpet weapon.
* Zahra Ghorbani from ''Literature/HeroesSaveTheWorld'' can make copies of herself, but they only remain for as long as they're in physical contact with her.

[[folder: Western Animation]]
* Lady Redundant Woman in ''WesternAnimation/WordGirl''.
* In ''WesternAnimation/DannyPhantom'', this is a rare power among ghosts. Vlad Plasmius can use it without difficulty. Danny himself spends most of the series trying to perfect it, and his evil future self (who incidentally absorbed Vlad's ghost half) has mastered it.
* The Ring of Nine Dragons in ''WesternAnimation/XiaolinShowdown'' allowed the user to duplicate him/herself, but cut his/her power into equal portions and leads to LiteralSplitPersonality.
* Billy Numerous in ''{{WesternAnimation/Teen Titans}}''. A particularly skilled one too, since he's able to create literally dozens of clones near-instantaneously with no power loss. Yes, he's only about as strong as the average man, but when you suddenly have 30 of them, all sucker-punching you from every angle, he's a fairly formidable villain.
* This is the power of LoonyFan Sebastian in the ''WesternAnimation/GeneratorRex'' episode "Rock My World".
* He doesn't normally have this power, but in one episode, WesternAnimation/SpongeBobSquarePants uses this to demonstrate that a lucid dreamer can do anything they want in a dream. "I can make a million of me!"
* Multi-Man of The Impossibles in ''WesternAnimation/FrankensteinJr'''s backup cartoon can, as his name suggests, make multiple copies of himself.
** The idea was recycled in ''WesternAnimation/TheSuperGlobetrotters''.
* ''Franchise/{{Ben 10}}'':
** Ditto from the [[WesternAnimation/{{Ben10}} original series]] could do this but if one of the copies was harmed it would affect everyone of them.
** Echo Echo from ''WesternAnimation/Ben10AlienForce'' can also do this and every copy is independent of itself, meaning Ben can keep one of them as backup in case anything bad happens to the others.
** In ''WesternAnimation/Ben10Omniverse'' we get to see Ditto's natural predator who can also self duplicate.
* Replay in ''WesternAnimation/StaticShock'', a FormerChildStar, who uses his copies to steal. They are shown to be separate individuals, but he has the ability to wipe them out from existence at will, thus keeping them in line.

[[folder: Real Life]]
* Certain species of plants, fungi, and bacteria have the power to form [[http://en.wikipedia.org/wiki/Clonal_colony clonal colonies]] where a single ancestor can reproduce vegetatively, not sexually, to form a large population of clones. Sometimes these clones are interconnected through roots and runners to form a [[IAmLegion single massive organism]] that is [[ExpendableClone practically immortal]].
** Most notable of these is [[http://en.wikipedia.org/wiki/Pando_%28tree%29 Pando]], a 100 acre large connected Quaking Aspen colony with 43,000 individuals estimated to be over [[ReallySevenHundredYearsOld 80,000 years old]].
*** The cloning ability was actually used to overcome the effects of climate change where the post ice age west was inhospitable for Aspen seedlings. Without young aspens or conifers, which were both sensitive to the arid environment, to compete with, the clonal colonies came to predominate. Some estimate that in some places Aspen have [[NoSexAllowed not reproduced sexually]] for 10,000 years.
* And when it comes to individual cells, there is of course mitosis in general, the form of cell division in which each daughter cell has a complete copy of the genetic code in the end. [[note]]As opposed to meiosis for the purpose of sexual reproduction, in which the daughter cells only get one half of all the genes.[[/note]] Though which of the genes get ''expressed'' after that, determining the individual cells' form and function, is another matter...
