History Main / SplitPersonalityTeam

* ''Fanfic/ThreesACrowdNaruto'' kicks off with [[PlotTriggeringDeath Naruto being murdered]], only to find his consciousness somehow inhabiting Sakura's body alongside [[BeneathTheMask Inner Sakura]]. While Sakura remains the dominant personality, the trio agree to work together in order to secretly investigate and figure out some solution to their plight, without fighting for control.
* The ''Franchise/LoveLive'' fic ''Fanfic/WhenOneBecomesMany'' reinvents the different idol groups as separate disassocative systems. In the original story, the systems were developed to protect their hosts from [[AbusiveParent abusive fathers]].

* ''ComicBook/MoonKnight'' has DID, but his three alters help each other to fight crime.

* ''VisualNovel/PhoenixWrightAceAttorneySpiritOfJustice'': [[spoiler:Uendo Toneido's characters,[[MultiGenderedSplitPersonalities Kisegawa]] and Patches, are revealed through testimony to be full blown split personalities, who work with him to enhance his [[https://en.wikipedia.org/wiki/Rakugo rakugo]] performances.]] Much of the case revolves around the question of whether the three are hiding a murderous fourth personality named Owen. [[spoiler:It turns out a fourth personality called Owen ''does'' exist, but he's just a timid little boy and not the murderer. [[AlternateIdentityAmnesia None of the other three share Owen's memories]], so their reaction to seeing their master's dead body was to hide any evidence that he might have done it, as they literally didn't know otherwise; in fact, he was a ''witness'' to the murder.]]

* In ''VideoGame/GrandiaII', Elena, a WhiteMagicianGirl by default, gains a SuperpoweredEvilSide, who is a PersonOfMassDestruction, as a result of DemonicPossession. When she becomes Millennia, usually right before a major boss battle, she helps the party, at first because their short-term goals coincide, and later because [[LoveRedeems she's in love with the main character]]. Just before the final boss, she gains a separate body and they are able to fight together.

* ''VideoGame/TheLegendOfZeldaFourSwords'': After pulling out the Four Sword, Link is split into four copies of himself, Green, Red, Blue and Purple. In the manga version, the four parts have different personalities: Green is energetic, Red is timid, Blue is hot-headed, and purple, called Vio, short for Violet, is calm and thoughtful.

* The ''VideoGame/Killer7'' use this as a gameplay mechanic, with all the Smiths playing differently, using different weapons, and having different skills despite being split personalities of one man (the twist being [[spoiler: that the one man is not the one that we think]]. They even appear to change form when they switch personalities and have their own health meters.

* ''Manga/JoJosBizarreAdventure'' has this in the form of [[Manga/JoJosBizarreAdventureGoldenWind Part 5]]'s main villain, Diavolo, and his split personality, [[spoiler:Doppio]]. Being extremely paranoid of people finding out his identity, Diavolo doesn't go out in public, preferring to "switch" to [[spoiler:Doppio]], who definitely seems more normal [[BerserkButton so long as you don't stick your nose too deep into his business]]...

* ''Anime/YuGiOh'': Before Yami's true nature and origin were revealed, everyone thought he was a SplitPersonality of Yugi (Yugi called him "other me"). As Yami was the better duellist and had the mind powers to punish cheating opponents, they switched out for battles. During their match against Pegasus, they relied on their bond and trust to duel him by switching between one another so Pegasus' mind reading won't work. However, it's later revealed that Yami is in fact the spirit of a Pharaoh from thousands of years ago who was sealed within the Millenium Puzzle and is connected to a much grander scheme, with a running theme being what the Pharaoh's name is. [[spoiler:Yami/Atem and Yugi's final duel serves to demonstrate that Yugi no longer needs Yami to fight for him, letting Yami move on to the afterlife.]]

* This is the point which Toko Fukawa and Genocider Syo/Genocide Jack in ''VideoGame/DanganronpaAnotherEpisodeUltraDespairGirls'' have reached after numerous years of the former being justifiably terrified of the latter. Toko has learned to control when Jack fronts (by shooting herself in the head with a taser) and Jack has quit being a man-hunting serial killer to use her power to instead slaughter armies of killer robots. In return, they’re pardoned for the tens of bodies they dropped before TheEndOfTheWorldAsWeKnowIt and are given an internship in the second-to-last government on Earth, which quickly becomes the last by the end of the prologue. Toko’s in charge unless they need to fight things, then Jack is called out to destroy everything in their path.
* In ''VideoGame/GrandiaII'' Elena, a WhiteMagicianGirl by default, gains a SuperpoweredEvilSide, who is a PersonOfMassDestruction, as a result of DemonicPossession. When she becomes Millennia, usually right before a major boss battle, she helps the party, at first because their short-term goals coincide, and later because [[LoveRedeems she's in love with the main character]]. Just before the final boss, she gains a separate body and they are able to fight together.

* ''VisualNovel/PhoenixWrightAceAttorneySpiritOfJustice'': [[spoiler:Uendo Toneido's characters,[[MultiGenderedSplitPersonalities Kisegawa]] and Patches, are revealed through testimony to be full blown split personalities, who work with him to enhance his [[https://en.wikipedia.org/wiki/Rakugo rakugo]] performances.]] Much of the case revolves around the question of whether the three are hiding a murderous fourth personality named Owen.

* In ''[[VisualNovel/ShallWeDateNinjaShadow Shall We Date?: Ninja Shadow]]'', [[spoiler:Kagura has a SplitPersonality, Homura, born from his horrifying DarkAndTroubledPast. The HotBlooded Homura was born to protect the gentle Kagura's frail mind after his trauma, and tends to take over when Kagura's either in battle or too stressed]].
[[/folder]]

* Invoked in ''WesternAnimation/SouthPark'': A psychiatrist diagnoses multiple personality disorder at Butters when he plays trucker, cowboy or detective. It then turns out that the psychiatrist himself has MPD and one of his personalities, a boy named Billy, tries to convince Butters to become "Inspector Butters" in order to solve a crime. Butters plays along, because the psychiatrist is armed and one of his personalities is ready to shoot him if he steps out of the line.

* Alpha Q in ''Anime/TransformersEnergon'' has a few, very distinct, separate personalities. Each personality has their own face. Overlaps with MultipleHeadcase and MindHive.

* Fai Films' ''WesternAnimation/FerngullyTheLastRainforest'' has TheHero Zack needs Batty Koda to fly him to the control section of the leveler, but Batty's instinctive fear of anything man-made obstructs this effort. Zack slaps Batty, which literally rewires the bat's brain, until Batty thinks that he's in a John Wayne movie, whereupon he bravely flies Zack to the GiantMecha.

* [[ComicBook/OutlawKid Lance Temple]] starts off ''ComicBook/BlazeOfGlory'' wanting to avenge himself upon his other personality, the Outlaw Kid, who he believes killed his father. In reality, it was the shock of discovering his son ''was'' the Outlaw Kid that killed his father. As the 4th issue begins, Lance starts coming to terms with the truth, and willingly [[TheHatMakesTheMan pulls his mask over his face]] to become the Outlaw Kid.
* ''ComicBook/TheCreeper'' and Jack Ryder are usually at odds, but they are this in the 1997 miniseries, with Jack providing his investigative skills and the Creeper handling combat. At first they are uneasy allies but eventually full-fledged partners when they are freed of their self-loathing in the ComicBook/DCOneMillion event.
* Rose and Thorn, also of DC, in some versions. The original is your basic JekyllAndHyde villain, but later on, there have been both rebooted versions of the original and entirely different characters later, where they're both good, but the civilian Rose is, well, a civilian but Thorn goes and takes care of business by night, with both having to leave each other messages. Some versions of the ''good'' Thorn can be pretty brutal and antihero-ish, though.

** Revisited in ''ComicBook/ImmortalHulk''. Bruce is active during the day and handles scientific knowledge or anything to do with rules or structure. The Immortal / Devil Hulk comes out at night and is more at home with gut feelings and doling out karmic punishments. Bruce can trade places with Joe Fixit if he needs Joe's cunning or is just emotionally overwhelmed; something similar applies to the Immortal and Savage Hulks. The Professor and the [[ComicBook/PlanetHulk Green Scar]] are conspicuous by their absence [[spoiler: until Xemnu starts messing with Bruce's head, at which point the Green Scar joins forces with the Savage Hulk to fight back.]]

* ''Comicbook/{{Shazam}}'': In the original 1940s/50s Creator/FawcettComics run of Captain Marvel, Cap and Billy Batson (along with Junior/Freddy and to a lesser extent Mary), their normal and empowered selves were this. After the DC revival, they became more single-personality {{Henshin Hero}}es.

* ''Manga/JoJosBizarreAdventure'' has this in the form of [[Manga/VentoAureo Part 5]]'s main villain, Diavolo, and his split personality, [[spoiler:Doppio.]] Being extremely paranoid of people finding out his identity, Diavolo doesn't go out in public, preferring to "switch" to [[spoiler:Doppio,]] who definitely seems more normal [[BerserkButton so long as you don't stick your nose too deep into his business...]]

* The ''VideoGame/MegaManX'' fanfic "[[https://www.fanfiction.net/s/12986811/1/The-Original-An-Axl-Story An Axl Story]]" has Axl share his body with Lumine, whose [[GrandTheftMe hostile takeover plot]] failed and ended up performing a HeelFaceTurn, and [[BackFromTheDead Iris]], explained by having her body be used as the basis for Axl's. Internally, they can communicate with Axl and interact with his functions, while externally, they can take advantage of his [[{{Shapeshifting}} A-Trans System]] to morph into their own forms and freely roam the world.

** Pinkie's Fullbring allows her to bring Pinkamena, who is the embodiment of her repressed negativity and emotions, into the physical world, and Pinkie eventually [[EquippableAlly becomes a hammer]] for Pinkamena to wield. [[spoiler:In the Camp Everfree arc, completing their Fullbring merges them physically together again, though they later reveal that they can separate again if needed, but allowing them to remain as distinct mental entities]].
** Twilight eventually manages to come to a mutual understanding with Midnight to the point where they begin working together in combat,[[spoiler: Twilight handling Quincy reishi manipulation and Midnight focusing on magic.]]

* ''Fanfic/TheImmortalGame'' weaponizes this, with Celestia [[spoiler:and eventually Twilight]] being able to split the mind into two: one to analyze the situation, the other to act on it. [[spoiler:And then we find out the Big Bad can do it too, and can split into a previously unprecedented '''three''' personae.]]
* The [[http://archiveofourown.org/series/59646 "Multicolored"]] series of ''Film/{{The Avengers|2012}}'' fanfiction expands Bruce Banner and the Hulk's relationship into a full Split Personality Team, introducing a bunch of additional alternates and explaining their personality and roles.

* A ''Franchise/KingdomHearts'' fanfic titled "[[http://www.fanfiction.net/s/4749737/1 Somebody Told Me]]" (now dormant, possibly [[DeadFic dead]]) presents Roxas and Naminé as alters of Sora but they get along, can communicate, even via a MentalWorld, and even try so that all three can live their own lives as best as possible. Part of the story at the time was dealing with Naminé's boyfriend Marluxia being brought into the loop and how his acceptance and subsequent behavior changes complicates Sora and (especially) Roxas' lives.

* A ''Series/Sense8,'' from the show of the same name, consists of eight people with a mental link, turning them into a collective HiveMind. Each original personality still exists, and can take over for someone in a situation where one person's skills is better suited to another person's problem.

* [[spoiler: The Voerman Sisters]] in ''VideoGame/VampireTheMasqueradeBloodlines''. Though initially hostile towards each other, the PlayerCharacter can convince the them to reconcile with one another.

* ''VisualNovel/PhoenixWrightAceAttorneySpiritOfJustice'': [[spoiler: Uendo Toneido's characters,[[MultiGenderedSplitPersonalities Kisegawa]] and Patches, are revealed through testimony to be full blown split personalities, who work with him to enhance his [[https://en.wikipedia.org/wiki/Rakugo rakugo]] performances.]] Much of the case revolves around the question of whether the three are hiding a murderous fourth personality named Owen.

[[spoiler: It turns out a fourth personality called Owen ''does'' exist, but he's just a timid little boy and not the murderer.]]

* ''Comicbook/DirtyPair'' (the 1990s Adam Warren {{Animesque}} comic book series): [[TheParagonAlwaysRebels Shasti]] was an ArtificialHuman created to exploit this trope, with four separate personalities she would switch between as her missions demanded. An attempt to temporarily load the personality of a psychopathic criminal her team was hunting drove her homicidally insane, but did not reduce her ability to use her alternate selves to become a criminal mastermind.

* In ''Anime/MobileSuitGundam00'', although they started out in a more standard JekyllAndHyde configuration, Allelujah and Hallelujah eventually develop into a duo that help each-other out depending on the required situation as well as occasionally [[SplitPersonalityMerge fusing]]. Allelujah acting as thought and moral while Hallelujah acts as instinct and drive. The [[IdenticalTwinIDTag visual cue]] to which personality is in charge at the moment is which eye is showing, with the left grey eye representing Allelujah, while the right gold eye is Hallelujah. Whichever personality is dormant will have their eye [[PeekABangs covered by their hair]]. But whenever they go all-out and fully merge, they sweep their bangs aside to show ''both'' eyes and become "the Super Soldier."

* In ''LightNovel/SoImASpiderSoWhat'', split personality is literally a power ("Parallel Minds") that characters can unlock by levelling up the multitasking skill ("Parallel Thought"). When the protagonist Kumoko unlocks this skill, she makes extensive use of it by dividing their work. "Information Mind" (Kumoko's original mind) [[ExactlyWhatItSaysOnTheTin handles processing information]] while "Body Mind" handles moving their body around. As she levels up Parallel Minds to gain more personalities, they become "Magic Mind #1" and "Magic Mind #2" whose job is to cast spells during battle so the other two minds don't have to focus any of their own attention on it. It's implied that the skill wasn't actually ''meant'' to be turned on permanently, but Kumoko was kind of insane to begin with.

* Shinobu Sensui from ''Manga/YuYuHakusho'' has seven personalities, created after a psychologically traumatic event to help carry his burdens. They could even converse with each other and convince each other to take a particular course of action. i.e, the suave ManipulativeBastard seen at the beginning is "Minoru", created to contact and deal with Sensui's followers, and when Yusuke manages to land a hit on "Minoru" Sensui switches to a personality named "Kazuya", who is an AxCrazy BloodKnight that handles the actual killing of the human beings Sensui hates so much.
* In ''Manga/{{Naruto}}'', Zetsu is the only Akatsuki member who doesn't go around in EvilDuo - his teammate is himself, i.e Black and White Zetsu. The white is goofy and gleeful while the black is serious. He can also split into two halves.

* ''Anime/YuGiOh'': Before Yami's true nature and origin were revealed, everyone thought he was a SplitPersonality of Yugi (Yugi called him "other me"). As Yami was the better duellist and had the mind powers to punish cheating opponents, they switched out for battles.

** Revisited in ''Anime/YuGiOhArcV'' where Yuya starts off alone but gains Yuto as an additional personality inside his body part way through the series.

When the protagonist Kumoko unlocks this skill, she makes extensive use of it by dividing their work.

* ''Breaking Twilight'' by [=OrphiusOlyandra=] gives us Pinkie and Pinkamena, the latter of whom embodies all of the bad parts of the former's life, which she had cut from her memory as if from pages in a book, and replacing them with happier FakeMemories[[labelnote:*]](We see her do this with some guards she killed to get out of captivity, where she is shown convincing herself she threw them a party instead.)[[/labelnote]] so she can live with herself. Pinkamena torments her over this, until they eventually team up to win the war and Pinkamena starts showing more benign traits. [[spoiler:And then a third one is accidentally created by Twilight's botched attempt at a Split Personality Merge, ultimately named "Pinks" as she's neither Pinkie nor Pinkamena, but somepony in between.]]

* The ''VideoGame/MegaManX'' fanfic "[[https://www.fanfiction.net/s/12986811/1/The-Original-An-Axl-Story An Axl Story]]" has Axl share his body with Lumine, whose [[GrandTheftMe hostile takeover plot]] failed and ended up performing a HeelFaceTurn, and [[BackFromTheDead Iris]], explained by having her body be used as the basis for Axl's. Internally, they can communicate with Axl and interact with his functions, while externally, they can take advantage of his [[{{Shapeshifting}} A-Trans System]] to morph into their own forms and freely roam the world.

* ''Literature/VorkosiganSaga'': This is explored in depth in ''Mirror Dance''. Mark Vorkosigan develops a Split Personality Team he dubs the "Black Gang" (because they do the dirty jobs) in order to survive and eventually escape ColdBloodedTorture. Three of the personalities are TooKinkyToTorture (in different ways) and one of them is a manifestation of Mark's assassin training. Mark's only regret is that he can't take ''his'' alternate personalities to a posh dinner like Miles can with Admiral Naismith.
* ''Literature/WhenRabbitHowls'': The Troops have some elements of this, although they don't always surface for practical reasons. Mean Joe protects the most vulnerable personalities, Grace the Zombie keeps going under immense strain, Black Katherine deals with rage, and so forth. They also don't sequester emotions to certain people. Each has his or her own full range of emotions, but handle them in different ways; through art, writing, work, etc.

* In the ''Literature/{{Voidskipper}}'' novel ''In Pursuit of Bark's Finest'', Madeline Zargosty is partnered with Maximus Hadrian (often simply called Max), a cyberwarfare expert who's been downloaded into the same morph as her. While they briefly separate for various purposes, they generally stay together. Notably, Max is recognized as an agent in his own right by the Bureau of Starforce Intelligence.

* In ''Literature/{{Blindsight}}'', multiple personalities are no longer considered to be a mental disorder and some people have them surgically induced for multi-tasking. The team's linguist, known as "The Gang", has four primary personas and dozens of partial personality nodes.
* In ''Literature/ArtemisFowl: The Atlantis Complex'', Artemis develops a second personality called Orion. After the BigBad brands Artemis with a rune of enthrallment, Artemis endures an electric shock in order to awaken Orion, who turns out to be unaffected by the rune and possesses martial arts prowess which Artemis does not, making him very useful in the conflict that follows.
* [[http://astraeasweb.net/plural/multiples-silverberg.html Multiples]] by Creator/RobertSilverberg. TwentyMinutesIntoTheFuture multiple personality is accepted and respected as a variant normal lifestyle, similar to being gay. Many groups form cooperating teams, keeping logs if they can't communicate directly. The main character, a singlet, first poses as a multiple, then tries experimental treatment to see if she can become multiple for real.
* By ''Literature/RhythmOfWar'', this is what Shallan's quasi-DID has evolved to, with three distinct personalities that communicate with each other and hand off control as needed: "Shallan" handles art, scholarship, and social interaction, "Veil" handles stealth and spycraft, and "Radiant" handles combat and stressful situations.

* In ''Series/TheFlash2014,'' the prime universe Killer Frost (the first we met was from an alternate universe) is at first a SuperpoweredEvilSide of Caitlin, but at the end of the season where she was introduced, she makes a HeelFaceTurn while ''not'' fully becoming Caitlin again. When we find them next season, each is clearly her own person, and Frost gets an arc of finding herself as an individual. Caitlin and Frost work together, with Caitlin being the scientist and Frost being the superhero, and care for each other a great deal.

* In ''VideoGame/GrandiaII'' Elena, a WhiteMagicianGirl by default, gains a SuperpoweredEvilSide, who is a PersonOfMassDestruction, as a result of DemonicPossession. When she becomes Millennia, usually right before a major boss battle, she helps the party, at first because their short-term goals coincide, and later because [[LoveRedeems she's in love with the main character]]. Just before the final boss, she gains a separate body and they are able to fight together.

* This is the point which Toko Fukawa and Genocider Syo/Genocide Jack in ''VideoGame/DanganronpaAnotherEpisodeUltraDespairGirls'' have reached after numerous years of the former being justifiably terrified of the latter. Toko has learned to control when Jack fronts (by shooting herself in the head with a taser) and Jack has quit being a man-hunting serial killer to use her power to instead slaughter armies of killer robots. In return, they’re pardoned for the tens of bodies they dropped before TheEndOfTheWorldAsWeKnowIt and are given an internship in the second-to-last government on Earth, which quickly becomes the last by the end of the prologue. Toko’s in charge unless they need to fight things, then Jack is called out to destroy everything in their path.
* Hel in ''VideoGame/{{Smite}}'' has a Light Side with a nice personality and a Dark Side with a nasty personality. While they tend to argue with each other, they split the job while fighting.

* ''VisualNovel/PhoenixWrightAceAttorneySpiritOfJustice'': [[spoiler: Uendo Toneido's characters,[[MultiGenderedSplitPersonalities Kisegawa]] and Patches, are revealed through testimony to be full blown split personalities, who work with him to enhance his [[https://en.wikipedia.org/wiki/Rakugo rakugo]] performances.]] Much of the case revolves around the question of whether the three are hiding a murderous fourth personality named Owen. [[spoiler: It turns out a fourth personality called Owen ''does'' exist, but he's just a timid little boy and not the murderer.]]

* Invoked in ''WesternAnimation/SouthPark'': A psychiatrist diagnoses multiple personality disorder at Butters when he plays trucker, cowboy or detective.

[[spoiler:Yami/Atem and Yugi's final duel serves to demonstrate that Yugi no longer needs Yami to fight for him, letting Yami move on to the afterlife.]]

* This is how Kevin's multiple personalities manifest in ''Film/{{Split}}''. [[NiceGuy Barry]] appears to be the most outgoing, [[SuperOCD Dennis]] originally came about to appease Kevin's mother in her demands that he keep things clean, while [[TheLeader Patricia]] is composed and organized and can direct some of the more volatile personalities, curbing their excesses. Kevin's therapist even comments on how well he does at his job and that he's one of her most consistent patients. [[spoiler:At least, that's how it used to be. Unfortunately, Patricia is evil and convinces Dennis and Hedwig to team up with her against the nicer personalities to summon [[AxCrazy the Beast]], [[SplitPersonalityTakeover submerging Barry and the rest]] in their quest to bring him about. And poor Kevin hasn't seen the light in ''two years''.]]

The Split-Personality Team is less horror-oriented than other SplitPersonalityTropes, because the alternates are generally on the core personality's side, or at least looking out for their shared welfare. It's more commonly used in psychologically oriented stories exploring the complexity of a character's fractured mind. Some RealLife accounts of Dissociative Identity Disorder report a similar phenomenon, which may have inspired the trope. Rather than trying to merge back into one individual, DID patients in treatment may prefer to work toward a psychologically healthy, though still separate, Split Personality Team.

* ''Comicbook/TheIncredibleHulk'':
** In the early 2000s Bruce Banner develops Lou Gehrig's Disease, which is killing him. He strikes a bargain with the various Hulks in his head (primarily the green Savage, gray Joe Fixit, and Professor personalities): they can come out whenever they think is appropriate, and in turn they keep Banner alive.

* ''Literature/{{Aristoi}}'' by Walter Jon Williams features a ruling class of people that pretty much have this as a superpower.
* [[{{Literature/Voidskipper}} In Pursuit of Bark's Finest:]] Madeline Zargosty is partnered with Maximus Hadrian (often simply called Max), a cyberwarfare expert who's been downloaded into the same morph as her. While they briefly separate for various purposes, they generally stay together. Notably, Max is recognized as an agent in his own right by the Bureau of Starforce Intelligence.
* ''Literature/JoesWorld'' by Creator/EricFlint: Wolfgang Laebmauntsforscynneweeld, wielding the twin powers of madness and amnesia, and is himself both "the main patient, the head psychiatrist, the chief tester as well as testee of experimental drugs, and the captain of the security guard" at the Begfat asylum that he himself founded, so he could have a home of his own.
* ''This Alien Shore'' by Creator/CeliaSFriedman: The main character Jamisia is on the run, and struggles to understand the Others, extra people who live in her head. In the space colonies, mental "disorders" have been accepted as variant normal (people paint their faces with ''kaja'' designs, associated with totemic animal spirits, to indicate what variances they have). The most prominent among the Others in the story are Derik, aggressive and impulsive; Raven, trained as a pilot and a technician; and Katlyn, the seductress. At the very end, [[spoiler: the group escapes to a safe area of space and is identified as belonging to a ''kaja'' called ''rusa'', a deer which in Japanese mythology sheltered within its body the spirits of lost souls]].
* ''Literature/{{Discworld}}'': Altogether Andrews is one of the CrazyHomelessPeople introduced in ''Literature/TheTruth'', whose eight or so personalities manifest themselves whenever they need to express their opinion, in this case whether selling newspapers constitutes work.
* In ''Literature/{{Blindsight}}'' multiple personalities are no longer considered to be a mental disorder and some people have them surgically induced for multi-tasking. The team's linguist, known as "The Gang" has four primary personas and dozens of partial personality nodes.

* ''Series/DoomPatrol'': This is how Crazy Jane's personas are supposed to work. Unfortunately for her, there's a reason she's a member of the [[SuperZeroes Doom Patrol]] instead of the Justice League: having a headspace full of close to 50 different personas, all of which have some sort of personality disorder, some of which are so extreme that they can't even comprehend how to take care of Jane's body when they're in control, does not lend itself to cooperation. A great deal of time in Jane-centric episodes is spent on the personas disagreeing with each other while Jane attempts to keep them in line and cooperating.

* In ''LightNovel/SoImASpiderSoWhat'', split personality is literally a power ("Parallel Minds") that characters can unlock by levelling up the multitasking skill ("Parallel Thought"). When the protagonist unlocks this skill, she makes extensive use of it by dividing their work. "Information Mind" (Kumoko's original mind) [[ExactlyWhatItSaysOnTheTin handles processing information]] while "Body Mind" handles moving their body around. As she levels up Parallel Minds to gain more personalities, they become "Magic Mind #1" and "Magic Mind #2" whose job is to cast spells during battle so the other two minds don't have to focus any of their own attention on it. It's implied that the skill wasn't actually ''meant'' to be turned on permamently, and but Kumoko was kind of insane to begin with.

* ''Anime/YuGiOh'': Before Yami's true nature and origin were revealed, everyone thought he was a SplitPersonality of Yugi (Yugi called him "other me"). As Yami was the better duellist and had the mind powers to punish cheating opponents, they switched out for battles. During their match against Pegasus, they relied on their bond and trust to duel him by switching between one another so Pegasus' mind reading won't work. However, it's later revealed that Yami is in fact the spirit of a Pharoah from thousands of years ago who was sealed within the Millenium Puzzle and is connected to a much grander scheme, with a running theme being what is the Pharoah's name. [[spoiler:Yami/Atem and Yugi's final duel serves to demonstrate that Yugi no longer needs Yami to fight for him, letting Yami move on to the afterlife.]]
