History Main / LiteralSplitPersonality

** One ''JLA'' storyline did this to the League's entire roster -- splitting Superman and Clark Kent, Batman and Bruce Wayne, etc. Hilarity spectacularly failed to ensue as [[FromBadToWorse things went on]]: Clark was [[BecomingTheMask scared of heights]] while Superman was losing his humanity, Bruce Wayne had no outlet for his rage at the criminal element while Batman lost his motivation, the Flash lost his connection to his human past while Wally West became lethargic and missed his dates with his wife, and Kyle Rayner was faced with a psychological breakdown without the ring to vent his creativity while Green Lantern lacked any imagination and just shot things. ComicBook/PlasticMan got split into Plas, who literally ''could not'' be serious, and Eel O'Brian, [[BeneathTheMask the ruthless and manipulative ex-career criminal.]] Only Franchise/WonderWoman and Aquaman were immune, and then only until they got hit with a second blast: Aquaman got split into fish and human, and Diana was split into clay statue and disembodied spirit... [[BatmanGambit which was exactly what she wanted to happen]].

* Many {{YouTube Poop}}s have [[Franchise/SuperMarioBros Luigi]] with split personalities, most often [[VideoGame/HotelMario Gay Luigi]] and [[WesternAnimation/SuperMarioBros Mama Luigi]]. [[ExaggeratedTrope Heck, even the split personalities have split personalities]]. They've had a few encounters. In "Final Hours", ''all of his forms'' were together witnessing [[MayanDoomsday the end of the world]]. [[spoiler: However, the end didn't happen.]]

* Many WebAnimation/{{YouTube Poop}}s have [[Franchise/SuperMarioBros Luigi]] with split personalities, most often [[VideoGame/HotelMario Gay Luigi]] and [[WesternAnimation/SuperMarioBros Mama Luigi]]. [[ExaggeratedTrope Heck, even the split personalities have split personalities]]. They've had a few encounters. In "Final Hours", ''all of his forms'' were together witnessing [[MayanDoomsday the end of the world]]. [[spoiler: However, the end didn't happen.]]

* ''Film/CultOfChucky'' reveals that thanks to a spell from voodoofordummies.com, Chucky has found the means to [[spoiler: split his soul into other dolls, the titular cult. One of these clones ends up [[BodySurf body surfing]] [[AndIMustScream into the body of Nica Pierce.]]]] It seems he's taught his accomplice Tiffany Valentine on how to do this as the ending reveals, [[spoiler: she's successfully split her soul into at least one Tiffany doll.]]

* Creator/RobinHobb seems to have discovered a new use for this in ''Literature/TheSoldierSon'' trilogy -- [[spoiler:it can solve TriangRelations]].

** In ''Series/KamenRiderFourze'', the [[MeaningfulName Gemini]] [[MonsterOfTheWeek Zodiarts]]' TransformationTrinket causes the user's dark side to manifest as a separate entity the first time it's activated. The dark side then attempts to strengthen its own existence by making people hate and distrust the original, making the "weaker" one become more fake (such as its face becoming a white mask); after 24 hours, whichever side is stronger becomes permanent while the weaker fades from existence forever. Unfortunately, this happens to [[GenkiGirl Yuuki]] when the bad guys force her to use the Gemini Switch, but our heroes manage to save her [[AlwaysClose just in time]].

** Mannimarco, an [[OurElvesAreDifferent Altmer]] {{necromancer}} known as the "[[AppropriatedAppellation King of Worms]]" who [[Characters/TheElderScrollsRecurringCharacters makes several appearances in the series]], had this occur to him. As an ImmortalitySeeker who [[GodhoodSeeker wished to become a god]], he first became the first mortal to become a [[OurLichesAreDifferent Lich]]. After his [[TheStarscream attempt to usurp]] [[GodOfEvil Molag Bal]], the [[OurGodsAreDifferent Daedric Prince]] of [[NamesToRunAwayFromReallyFast Domination]] and [[TheCorrupter Corruption]], during the events of ''[[VideoGame/TheElderScrollsOnline Online]]'' failed, he hatched another plan to seize the Mantella, an unimaginably powerful soul gem and power source for the [[RealityWarper reality warping]] [[HumongousMecha Numidium]] during the events of ''[[VideoGame/TheElderScrollsIIDaggerfall Daggerfall]]''. This plan succeeded...[[MindScrew sort of]]. Due to an event known as the "[[TimeCrash Warp in the West]]", all of ''Daggerfall'''s mutually exclusive endings happened at once, and [[BroadStrokes none to the same extent they would have individually]]. This seemingly created two beings out of Mannimarco, the "God of Worms" who ascended to divinity and the "King of Worms", a powerful lich who leads a [[ReligionOfEvil cult which worships the God of Worms]]. These two now seem to be treated as separate entities.

** Evil Jordan is Jordan's [[EnemyWithin evil side]] who tries taking over as the dominant personality in the ''VideoGame/SilentHill3'' review. Half of his face (and hand) is [[RedAndBlackAndEvilAllOver painted black with one]] [[RedEyesTakeWarning red eye]].

* [[WebVideo/ThomasSanders Thomas Sanders]] has a web series titled ''WebVideo/SandersSides'' where he has long conversations and debates with personifications of the different aspects of his personality, who try to help him find solutions to his personal or existential issues in his daily life.

* Spoofed in an episode of ''WesternAnimation/TheRenAndStimpyShow''. Ren gets split in two, but instead of getting split into a good and evil side, he gets split into an evil side, and an ''indifferent'' side. Later, Evil Ren tries to clone himself, but only gets split again into Evil Ren, and ''Hideously'' Evil Ren. Who, for some reason, [[OppositeSexClone is female]]. [[ScrewYourself And the two evil Rens fell in love]] [[UnholyMatrimony and promptly got married.]] And they expressed their love by constantly punching each other.

* Much like the ''Franchise/SilentHill'' video games, in the film ''Film/SilentHill'' the psychic little girl Alessa Gillespie split into two after enduring terrible trauma: the menacing CreepyChild "Dark Alessa", and the innocent Sharon Da Silva, adopted daughter of the film's protagonists. This trope is still present in the sequel ''Film/SilentHillRevelation3D'', where Sharon and her adoptive father have renamed themselves (she's now Heather Mason).

** "Demons and Angels" featured a triplication device, which created a Good Ship with crew (who exist in the starship equivalent of CrystalSpiresAndTogas, and can even make Pot Noodles edible), an Evil Ship with crew (where Rimmer's H has fallen sideways and... yeah) and a Neutral Ship with crew (i.e. the original gang). The Neutral Ship duly exploded, and it required a [[ReverseThePolarity polarity reversal]] to recreate it from the others.
** There's also "Confidence and Paranoia" in one of the early series, except that these were just manifestations of aspects of Lister's personality caused by his highly evolved pneumonia rather than Lister splitting himself.

* ''Series/{{Warehouse 13}}'':

* A hostile demon's spell intended to separate Buffy's personality from her Slayer abilities in an episode of ''Series/BuffyTheVampireSlayer'' hits Xander instead, separating him into an "aggressive" Xander (charming, well-groomed, and confident; but hot-headed and impetuous) and a "passive" Xander (awkward, clumsy, paranoid, and insecure; but with Xander's trademark sense of humor and good spirit). Note that despite the passive Xander's suspicions, neither half is actually evil, and they actually get along very well once they meet each other. Both Xanders also refer to ''Star Trek'''s "The Enemy Within" during the episode.
** Once the group learn what the spell did, they speculate that the demon's intention was to split Buffy into the purely human 'Buffy-Buffy' and the ruthless Slayer 'Slayer-Buffy' and then use the existing connection between the two to kill the more vulnerable 'Buffy-Buffy' in order to kill both of them.

* In ''LightNovel/DateALive'', Kurumi Tokisaki can make clones of herself. While they are usually just extensions of her, some manifest their own personality. The regular Kurumi is an AxCrazy murderer and {{Yandere}}. One of her clones is sweet and genuinely falls in love with Shido. Even if her clones are destroyed, they can eventually manifest again.

* ''LightNovel/FateZero'': Assassin, Hassan of the Hundred Faces, was in life a man with multiple personalities, some of them women and children. His Noble Phantasm, Zabaniya: Delusional Illusion, allows him give each of his personalities their own body. Though contrary to his name, he only has eighty of them. If any of them are killed, they are gone for good, but all of them need to be killed to truly end him. Unfortunately for him, his strength is divided between each body, so they are relatively easy to defeat in straight up combat.

* Sasha and Misha Necron of ''LightNovel/TheMisfitOfDemonKingAcademy'' are initially introduced as twin sisters but are actually [[spoiler:the forcibly split halves of Sasha, the original.]]

* In ''Anime/{{Pokemon}}'', Sabrina's shunning of her emotions in favor of focusing solely on training her psychic powers eventually caused her emotional side to split off into a CreepyDoll-like body. When a Haunter Ash had befriended got her to laugh she underwent a SplitPersonalityMerge and learned to embrace her emotions.

* ''Series/{{Farscape}}'': Seen in "My Three Crichtons", wherein John is split into a PowerTrio: the original (ego), an animalistic version that acts purely on emotion (id), and a hyperevolved version that acts purely on the basis of logic and self-preservation (superego). Interestingly, the id is the most heroic of the trio.

-->"Can half a man live?"

* In the ''WesternAnimation/Ben10UltimateAlien'' episode "Duped", Ben as Echo Echo splits into three Echo Echo clones, before each one turns human. Each of the Ben's represent a core aspect of Ben's personality, including: logical Ben, [[InTouchWithHisFeminineSide sensitive]] Ben, and [[{{Jerkass}} arrogant]] Ben.

* The main premise of the manga ''Rokuhime wa Kami Goei ni Koi wo Suru'' is about the reincarnated guardian Lloyd seeking out his empress Azumaria after a thousand year promise to reunite. Lloyd found out in chapter 4 that Azumaria's soul was split into six people, and his best chance to find them is to enroll into the magic academy. Although Lloyd does not know their identities, the manga heavily indicated that the six princesses that Lloyd met in the academy are indeed Azumaria's reincarnation, and the six princesses eventually fall for Lloyd as the story progresses.

* In ''VideoGame/BreathOfFireI'', the party enters the mind of Mogu, who is in a coma, to find his personality fractured. They have to find his missing Courage in order to bring them together and wake Mogu up.
* ''VideoGame/BreathOfFireIV'': Ryu (the protagonist) and Fou-lu (the antagonist) are [[spoiler:actually two halves of the same god, the Yorae Dragon/Arukai no Ryuu, that was summoned 600 years ago on the western continent in a desperate attempt to stop a massive civil war. Unfortunately, the summoning was botched; only half the god made it across straightaway (becoming the first emperor of the Fou Empire), the other half ending up landing 600 years in the future and literally halfway across the world. (The Fou Empire and its precessor do ''not'' have a good track record at successful summonings.)]] It should be noted the original split isn't good/evil here, but rather along Yin/Yang aspects. [[spoiler:Fou-lu is the yin/water/cold aligned half, while Ryu is the yang/fire/heat aligned half). Fou-lu is actually neutral at first; he ends up going to OmnicidalManiac thanks to having his girlfriend used as a Tactical Thermonuclear Curse Peasant in a deliberate attempt to kill him by the very empire he founded (which does ''not'' want to give up its regency to him).]]

* It's eventually revealed in light novel 29 of ''Literature/InvadersOfTheRokujyouma'' that the Goddess of Dawn split herself into 9 individual females who end up becoming MC Kotarou's love interests. All 9 girls possess parts of the Goddess's powers, abilities and worries. The Goddess did it out of loneliness, hoping that Kotarou could accept her for who she is as everyone else who came before Kotarou failed to meet her expectations. Kotarou accepted all of her and the Goddess, moved into tears, followed Kotarou's request to become human and erasing her and everyone else's memories to led a normal human life.

* In the light novel ''I Was Caught Up In A Hero Summoning, But That World Is At Peace'', Shallow Vernal, aka Shiro, split herself into two, with the other half being [[spoiler:the main heroine Kuromueina]]. Despite both having different personalities, both end up loving the MC Kaito.

* Many WebAnimation/{{YouTube Poop}}s have [[Franchise/SuperMarioBros Luigi]] with split personalities, most often [[VideoGame/HotelMario Gay Luigi]] and [[WesternAnimation/SuperMarioBros Mama Luigi]]. [[ExaggeratedTrope Heck, even the split personalities have split personalities]]. They've had a few encounters. In "Final Hours", ''all of his forms'' were together witnessing [[MayanDoomsday the end of the world]]. [[spoiler: However, the end didn't happen.]]
* [[AxCrazy Flandre]] from ''Franchise/TouhouProject'' is a mentally unstable little sister locked in a basement. She can split herself into four using her spellcard [[MesACrowd Four Of A Kind]], and fan works often depict the clones as expressions of different aspects of her psyche. For an example, Aozora Market created a [[http://g.e-hentai.org/g/149389/44dba39894/ doujin]] where she asked permission to go shopping in the village, and used Four of a Kind to spread the unstable parts of her personality around. One of them manages to buy the thing she wants, but not before the rest of them create chaos in the mansion.

* Basically applies in "[[https://www.fanfiction.net/s/12638414/1/Pokemon-Dark-Multiverse Pokemon: Dark Multiverse]]" when the [[ComicBook/DarkNightsMetal Dark Knights]] attack the ''[[Anime/PokemonTheSeries Pokemon]]'' world; an attack by Arceus splits the Red Death back into his separate personas of Bruce Wayne and Barry Allen, [[spoiler:prompting Barry to join the heroes opposing the other Knights and the Bruce that had been part of the Red Death finally accepting that he was wrong when confronted by his prime reality counterpart]].
* "[[https://www.fanfiction.net/s/6688142/1/The-Sister-in-the-Door The Sister in the Door]]" is based on the premise that Seeley Booth (''Series/{{Bones}}'') is the human identity of Angel (''Series/{{Angel}}'') after he achieved Shanshu. However, Booth's tumour is revealed to have been the work of the First Evil, with the operation to remove the tumour from Booth's brain allowing the First's agents to arrange for the part of Booth that is still Angelus to manifest as a separate entity.
* "[[https://archiveofourown.org/works/40367694/ Doctor Who in the Multiverse of Madness]]" sees a spiritual version of this; when the Thirteenth Doctor (''Series/DoctorWho'') finds herself, Dan and Yaz in the Franchise/MarvelCinematicUniverse, Wong decides to question the Doctor by expelling her astral form from her body, only for this to result in the Doctor's past incarnations manifesting as well.

* The ''Series/BuffyTheVampireSlayer'' fic ''Fanfic/TheOneWithTheAngelicFace'' sees Angela (the female version of Angel in this series) split into the female human and male vampire identity after Drusilla borrows Toth's weapon. However, [[spoiler:as the two halves literally need each other to exist in this dimension, eventually Angela will revert to her 'natural' state of a two-centuries-plus corpse while Angelus will become a pure vampire demon and be unable to exist on this plane, forcing the gang to merge the two identities back together before Angela dies]].
* In ''[[http://www.fanfiction.net/s/860445/1/Prism Prism]]'', [[Manga/RurouniKenshin Kenshin]] is split into a thirty year old version of himself, a teenage self, and a child self. Some different aspects of his personality end up split among them as well, such as the teenage version having a short temper and little self-control, most of which went to the adult version.
* ''Fanfic/OneStepBackwardsAndThreeForwards'': As a result of the reality-altering Wishes made by [[TheBadGuyWins Hawkmoth]] and his supporters, Adrien is split into two individuals in the new world: Felix Agreste, who [[RippleProofMemory remembers his past life]], and his younger brother Adrien, who exists to fulfill Lila's Wish of having him as her MealTicket.
* ''Fanfic/FromFakeDreams'': The Edefelt sisters' summoning of Medea results in this. Luvia has the nicer Princess incarnation, Marjatta the more cruel Witch incarnation. This is reflected in their Noble Phantasms and skills.
* In ''Fanfic/HellsisterTrilogy'', [[ComicBook/LegionOfSuperHeroes Legion's nemesis]] [[EvilSorcerer Mordru]] uses her magic to resurrect Satan Girl, ComicBook/{{Supergirl}}'s evil clone fashioned from her inner darkness.

* In the ''WesternAnimation/TheGhostAndMollyMcGee'' fanfic [[https://archiveofourown.org/works/37897201 "Split Persona-Libby]]", Molly's best friend (and [[FanPreferredCouple recently girlfriend]]) Libby gets split into five clones of herself, each representing an aspect of her personality: there's a Smart Libby who's [[TheSpock logical but unemotional]]; a Sarcastic Libby who's [[DeadpanSnarker snarky and bad-tempered]], a Shy Libby who's [[ShrinkingViolet nervous and bashful]], a Lovestruck Libby who's [[SickeninglySweethearts touchy-feely and optimistic]], and a Creative Libby who's [[MrImagination melodramatic, imaginative]], and prone to acting like a FilmNoir detective.

* In the opera ''Theatre/{{Eurydice}}'', Orpheus has a double that adds emphasis to several of his songs that represents his heroic quest, contrasting with the regular-guy Orpheus.

* In ''VideoGame/Drakengard3'', Zero suspects this is the case of the other Intoners. They were spawned by [[BotanicalAbomination the Flower]] when it resurrected her, modeling them off other women Zero knew in life, while shaping their personalities around aspects of her own. Five represents her materialism, Four her MadonnaWhoreComplex, Three her insanity, Two her dreams for a happier life, and One her efforts to rationalize the CrapsackWorld she lived in. The fact that none of the other Intoners is a complete individual helps explain their psychological instability.

* In ''Franchise/KingdomHearts'':

* The ''VideoGame/MegaManX'' series has a few examples. [[AllThereInTheManual According to supplementary materials]], Colonel and Iris were the result of a failed attempt to create a second Mega Man X, but the part of the AI representing X's compassion rejected the part responsible for his martial prowess, or vice versa, so they had to be split off into sperate bodies. There's also the obscure [[NoExportForYou manga and trading card series]] character IX (Irregular X, presumably he'd be called [=MaX=] if he ever showed up in the English version), an evil clone of X made up of all his negative emotions created by parasitic NanoMachines. And then in ''VideoGame/MegaManZero'' it turns out that [[spoiler:the title character himself is one of these, being a cheap knockoff of the real Zero's body that was used by the evil Dr. Weil to siphon off all the good personality traits that Dr. Cain implanted in him, leaving behind the raging psychopath, known as Omega Zero, that Dr. Wily intended him to be.]]
* In ''VideoGame/MegaManStarForce'', [[spoiler: Pat]] has a split personality, [[spoiler: Rey]]. Gemini becomes his EM wave partner. When he EM Wave Changes and becomes Gemini Spark, Gemini splits into two, and the two personalities split. Gemini Spark White merges with [[spoiler: Pat]]. The dominant one (the one you hit to damage), Gemini Spark Black, merges with [[spoiler: Rey]]. Thank Capcom for small blessings; in ''Star Force 2'', both of them are damageable separately.

* ''[[VideoGame/{{Onmyoji}} Onmyōji]]'': In the past, [[spoiler: Abe no Seimei]] performed a spell that split himself into [[spoiler: a Yang personality that is the Seimei we know and a Yin personality known as [[EvilCounterpart Kuro Seimei]], effectively [[CreateYourOwnVillain creating the]] BigBad.]]
* In ''VideoGame/Persona4'' ''[[UpdatedRerelease Golden]]'', [[spoiler: it's revealed that Marie was once the goddess [[Myth/JapaneseMythology Izanami-no-Mikoto]] but her existence was fractured by mankind's changing nature and she was split into Marie, Kunino-sagiri, Ameno-sagiri, and [[GreaterScopeVillain Izanami-no-Okami]]. In the GoldenEnding she [[PhysicalGod regains her power and uses it to create ideal weather for Inaba]].]]
* In ''VideoGame/Persona5'', [[spoiler: this is what twins Caroline and Justine really are. [[BigBad Yaldabaoth]] split ''Lavenza'' into Caroline and Justine so she didn't realize he disguises himself as [[BigGood Igor]].]]

* In ''VideoGame/ThreeDDotGameHeroes'', [[spoiler: Princess Iris is secretly split into three fairies, Ai, Lee, and Sue (Lee is your FairyCompanion for the adventure, Ai and Sue can be discovered in caves.]]

* ''VideoGame/LeagueOfLegends'' does this to ''TheGrimReaper'', manifest as [[TheDividual a dual entity]] of Lamb and Wolf, collectively known as Kindred. The apocryphal story was that there was once "a pale man" who was very lonely because [[PrimalFear everyone was terrified at having to meet him at the end of their lives]], so he split himself into two selves so he would always have a friend. Lamb is a stoic, absolute, but [[DontFearTheReaper serene version of Death who invites mortals to a peaceful passing]], while Wolf is an aggressive, primal version of Death [[TheProblemWithFightingDeath that hunts those trying to avoid their fate until he inevitably wins.]]

* ''Franchise/WhenTheyCry'': WordOfGod for the series is that [[spoiler:Bernkastel]] from ''VisualNovel/UminekoWhenTheyCry'' is a collection of ''VisualNovel/HigurashiWhenTheyCry'''s [[spoiler:Rika]]'s memories [[spoiler:of all the Fragments where she died]].

* In [[http://dresdencodak.com/2006/05/17/anagoge-starring-tiny-carl-jung/ this]] ''Webcomic/DresdenCodak'' strip, Kimiko suddenly, somehow has a red-coloured, extroverted copy of herself split off from her. Extrovert Kimiko then proceeds to run off with the guy that Introvert Kimiko was spying on.
* ''Webcomic/TheWotch'': In the 2003 "[=SchizophrANNEia=]" arc, Anne tries to fulfill multiple commitments by using a spell to make identical copies of herself. Turns out that each copy represents a different emotion, and furthermore each new copy diminishes the original incrementally. Needless to say much HilarityEnsues before Anne is finally able to pull herself together.

* In ''VideoGame/DragonQuestXI'', it's revealed that the RedOniBlueOni identical twins Veronica & Serena are the split reincarnation of one of the original [[ChosenOne Luminary]]'s companions.

Kotarou accepted all of her and the Goddess, moved into tears, followed Kotarou's request to become human and erasing her and everyone else's memories to led a normal human life.

* In ''Animation/BoBoiBoy'', the eponymous character has the ability to [[SelfDuplication create duplicates of himself]] with different ElementalPowers and distinct personalities:

'''Starscream:''' So... which part of me did ''[[OppositeSexClone you]]'' come from?\\

* ''Videogame/FallenLondon:'' ''Weaponized'' in order to subdivide a creature normally unkillable to humans into multiple formidable but killable beings. [[spoiler:In the Bag a Legend ambition, this is what the [[PhlebotinumBomb Chorister Bomb]] truly does: Split up the Vake/Mr. Veils into its myriad components and representations; most of them are too small to last, but three remain that you must kill (though you can keep one for yourself): Veils the Intriguer, his Chessmaster side that must be OutGambitted to death, Vake Veils, the hunter from beyond the stars that must be Slaughtered following a strict calendar, and Veils of the Third City, who represents his particularly involved reign in the Third City and must be killed with a weapon that can reach through time]].

** Once the group learn what the spell did, they speculate that the intention was to split Buffy into the purely human 'Buffy-Buffy' and the ruthless Slayer 'Slayer-Buffy' and then use the existing connection between the two to kill 'Buffy-Buffy' to kill both of them.

* Occurred in an episode of ''Series/SabrinaTheTeenageWitch''. When everyone was pressuring Sabrina to go to a different college (or in Aunt Hilda's case, to go backpacking), she ended up splitting herself into four different versions of herself without anyone knowing. Apparently even she didn't know about it herself until all four Sabrinas met up towards the end of the episode and reintegrated, realizing they had to do what Sabrina wanted to do.
