4	->''"For years, I'd been treating the Hulk like he's some kind of disease, something to get rid of. But then I started looking at him as the cure. Eighteen months in a gamma lab. I put the brains and the brawn together. And now look at me. Best of both worlds."''

7	So Bob is also [[SplitPersonality Charlie]], maybe even with a little [[GhostInTheMachine Albert hiding in there somewhere.]] There are many possible reasons for the existence of these [[SplitPersonality split personalities]], but this co-habitation is rarely peaceful or long lasting, inevitably resulting in a BattleInTheCenterOfTheMind to try and find out which [[SplitPersonalityTakeover personality will take over]]. Sometimes though, the winner might not reduce the loser to a [[NotSoImaginaryFriend tiny, powerless voice]] or [[LossOfIdentity destroy it completely]], and instead offers to become one again. With a little EpiphanyTherapy, AppliedPhlebotinum or even actual psychotherapy, they merge into a single, whole person that is greater than the sum of its minds.
8
9	The resulting merged personality is usually a composite of the parts that is well and truly psychologically stable. This is especially true if they were an [[TheMcCoy id]], [[TheKirk ego]], and [[TheSpock super ego]]. If they were [[GoodAngelBadAngel moral]] or [[RedOniBlueOni temperamental]] opposites, the resulting merged personality will keep traits of both. In more action-driven works, this merger includes combat ability and powers, so if the character had a [[CrouchingMoronHiddenBadass moron and a badass]] coexisting, the united whole will be a badass all the time... while occasionally tripping on banana peels. Similarly, if the reason for the personality split was to seal awesome cosmic powers away (resulting in a SuperPoweredEvilSide; see both EnemyWithin and EnemyWithout) the united self will have full control over these powers without risk of SuperPowerMeltdown or corruption. If the integration isn't a completely smooth ride, however, expect aftereffects similar to AmnesiacDissonance. A character with a case of SplitMindSplitPowers might result in a personality [[AllYourPowersCombined with all the powers of each separate personality]].
10
11	This has notably been the accepted method of treatment of those with Dissociative Identity Disorder (DID) by psychiatrists, though many in the plural community question if it is always the best choice, advocating a case-by-case basis for treatment.

18	[[folder:Anime and Manga]]
19	* ''{{Anime/Bakugan}}'': [[TheHeavy Masqurade]], the sadistic, evil, and powerful Brawler that plagues the main cast, is actually [[spoiler:''Alice,'' the soft-spoken FriendToAllLivingThings, [[NonActionGuy Non-Action Girl]] of the team. She was around her [[MadScientist grandfather's]] laboratory at the time of an accident, creating a JekyllAndHyde personality that occasionally hijacked her. After [[TomatoInTheMirror she finds this out]] she initially runs away to avoid harming the team. Ultimately, she comes to peace with and lays the Masquarade personality to rest, who becomes a SpiritAdvisor to her in Brawling. This also leads to her becoming an ActionGirl (who still keeps her NiceGirl personality).]]
20	* In ''Manga/{{Bleach}}'', Ichigo's power manifested in the forms of Zangetsu, his Zanpakuto, and his Inner Hollow. In time, [[spoiler: he comes to dominate both of them, learning how to use their power for himself. He also tends to take on aspects of their personality and appearance when using their power, such as the coat he acquires in Bankai mode and the mask and personality changes that accompany his Hollowfication. Near the end of the Arrancar arc, Zangetsu and the Inner Hollow merged themselves while Tensa Zangetsu was trying to teach Ichigo the [[EleventhHourSuperPower Final Getsuga]]. The resulting entity appears as Tensa Zangetsu wearing a white robe instead of a black one, and having the top part of the Inner Hollow's super evolved mask. However, his personality largely remain as that of Zangetsu's. Ichigo then merges with THIS personality, and takes on its confidence and... moodiness. Also, the inner hollow turns out to be a merger of his Actual Soul Reaper powers and the hollow powers, while Zangetsu is his Quincy powers.]]
21	* ''Manga/Change123'' is all about trying to merge the personalities of Motoko and [=HiFuMi=] [[spoiler:and Zero]].
22	* Done uniquely in ''Anime/Danganronpa3TheEndOfHopesPeakHighSchool''. [[spoiler:One of the main characters, Hajime, underwent a surgery that replaced his personality with a different one, which was then renamed Izuru. After [[VisualNovel/Danganronpa2GoodbyeDespair the events of the second game]], the two of them managed to reach an accord and merge, signified by heterochromia--one eye Hajime's green, the other Izuru's red. However, rather than one of them being dominant, the resulting persona has traits from them ''both'', and upon being asked which name he goes by in the OVA simply says "either is fine".]]
23	* ''Manga/DeathNote'': Light Yagami has a minor variation of this when he regains his memories, making this one of the rare unhealthy villainous examples.
24	* In ''Manga/DemonSlayerKimetsuNoYaiba'', Zenitsu’s usual cowardice and loudness greatly contrasts with his serious side he can only access when asleep or unconscious. But as he [[CharacterDevelopment grows]], he starts speaking in full sentences instead of just “Thunder Breathing, First Form! Thunderclap and Flash (insert variation)!” and is implied to only fall asleep, indicated by a SnotBubble, meaning he gains a higher level of consciousness while in trance mode. He also starts acting seriously while awake, like when he angrily stopped [[BigBad Daki]] torturing a little girl. It all culminates in him [[spoiler:outright abandoning the need to become asleep or unconscious to fight seriously, as he did against Kaigaku and in the final battle against Muzan, but would still sometimes show his usual [[NoIndoorVoice loud]] [[LargeHam personality]] outside of battle]].
25	* ''Anime/DragonBallZ'':
26	** Centuries after the unnamed Namekian refugee developed a LiteralSplitPersonality that created Kami and King Piccolo, Kami physically and mentally merges with the latter's {{reincarnation}}. However, the resulting individual still looks like, acts like, and is called "Piccolo". Not to be confused with the time [[FusionDance Piccolo fused with Nail]], a completely different and unrelated ([[IdenticalStranger though identical-looking]]) Namekian.
27	** The Buu Saga liked to play with this. For starters, the FusionDance merges two fighters' personalities as well as their appearances. After that, Majin Buu is absorbed by his [[EnemyWithout dark side]], but the new hybrid form is restrained from killing some people due to his good side's influence.
28	** In ''Anime/DragonBallGT'', Good Buu merges with Uub, the reincarnation of Kid Buu, to become Majuub in order to become powerful enough to fight Baby Vegeta.
29	* ''Franchise/{{Gundam}}'':
30	** In ''Anime/MobileSuitGundam00'', Allelujah Haptism temporarily merges with his violent SplitPersonality Hallelujah Haptism to become "the SuperSoldier" with the piloting skills of two men. This is visually demonstrated by the fact that Allelujah always has his right eye covered by his hair, while when Hallelujah takes over, he sweeps the hair over to cover his left eye instead. When both personalities work together, both eyes are exposed (and he speaks with both voices and personalities in turn).
31	** Similar situation with Une in an earlier series, ''Anime/MobileSuitGundamWing''. Lady Une has two personalities, "Iron Une", a cold-hearted and ruthless military commander and "Saint Une", who is kind and gentle but ineffectual. She spending about half the series in a coma and wakes up a couple of episodes before the finale, having resolved the conflict and now combining the military skill with the compassion.
32	* ''Manga/HoshinEngi'' has this with Taikobo and [[spoiler:Ou Eki]]. They later [[spoiler:merge together to become Fukki]], although [[spoiler:Taikobo is the main, dominating personality]].
33	* ''Manga/KaguyaSamaLoveIsWar'' has a downplayed example. Kaguya explicitly does not have split personality disorder, but she vacillates wildly between her emotional, vulnerable "self" and the "self" that is paranoid and [[DarkAndTroubledPast trauma]]-based. Ice Kaguya (as the latter is known) thinks of her other as stupid, and Kaguya-chan thinks of her other as heartless. After several internal screaming matches, the two accept that they both have a reason for existing, and Kaguya comes closer to being her true self: a girl who can protect herself from her [[AbusiveParents family]] if needed, but who is also able to appreciate the peace and friendships that give life meaning.
34	* In ''[[Anime/PrettySammy Magical Project S]]'', Misao becomes a lot stronger mentally when she accepts her Pixy Misa DarkMagicalGirl persona. (And has full control when turning into Pixy Misa later.)
35	* Hikaru and [[EnemyWithout Nova]] in ''Manga/MagicKnightRayearth'', when Hikaru comes to realize [[spoiler: Nova was created from Hikaru's feelings of guilt and regret for killing Princess Emeraude, and finally learns to accept these feelings and forgive herself]].
36	%%* Happens at the end of the ''Manga/{{Mahoraba}}'' manga.
37	* Zigzagged a bit in the anime ending of ''Manga/{{MAR}}''. [[spoiler: Snow was a clone created from a piece of Koyuki's soul. Making them not so much split personalities so much as original and copy. In the end, Snow merges back into Koyuki to become one whole person to be with Ginta on Earth. The ending seems to indicate a complete merge of both sets of memories, while retaining the same personality. It helps they essentially acted as the same person anyway.]]
38	* ''Manga/{{Naruto}}'':
39	** The final arc reveals that Kurama was split in half when Minato performed the Reaper Death Seal on him. His Yin half was trapped alongside Minato in the belly of the Death God, while the Yang half was sealed into baby Naruto. Both are merged back at the conclusion of the series.
40	** This is one of the goals of the Eye of the Moon Plan, which requires the union of the nine Tailed Beasts into the single being where they originated from: the Ten Tails. Unlike the case with the Yin and Yang halves of Kurama, this is viewed in a negative light, as it is made clear that the nine are distinct beings with their own personalities, and certainly do not want to become erased just to recreate the Ten Tails.
41	%%* Happens to Yaya in the end of ''Manga/{{Othello}}''.
42	* ''Manga/RosarioPlusVampire'': Even after [[spoiler: the destruction of the [[RestrainingBolt rosary]] and her seeming [[DeathOfPersonality demise]], Outer Moka's soul still exists within Inner Moka's body, and by the final chapter, the two have become one, signified by Inner Moka's silver hair turning pink at the ends. This merger overlapped so completely with Inner Moka's own [[DefrostingIceQueen defrosting]] that nobody other than her father (not even newly merged Moka herself) realized it was happening at first]].
43	* In ''Anime/ShamanicPrincess'', the heroine, Tiara, confronts her uncontrolled magical powers in the form of a shadowy, seductive EnemyWithout. It gets the better of her at first, but eventually Tiara realizes its power is a result of her fear, so [[ImNotAfraidOfYou she asserts herself]] and [[NeckLift shows it who's boss]]. It merges into Tiara, giving her access to her SuperMode for the first time.
44	* ''Manga/WChange'' both inverts this, then plays it straight. Maki's two personalities used to be one entity -- with the "light" side representing her happiness and joy and the "dark" sight representing her anger and sorrow, but they diverged into two separate beings at some point. Later, the personalities merged back together, allowing Maki to switch between her two sides at whim.
45	* ''Franchise/YuGiOh'':
46	** Often overlooked in the English dub of ''Anime/YuGiOh'', Yugi and the pharaoh usually combine their minds when dueling. The reason this is overlooked is because Yugi merged with the pharaoh looks pretty much exactly like the pharaoh all by himself. On account of the pharaoh looking like an older version of Yugi.
47	** In ''Anime/YuGiOhGX'', this occurs during his final duel against Yubel when Jaden accepts that he is the Supreme King, and no longer fears or denies that power.
48	[[/folder]]
49
50	[[folder:Asian Animation]]
51	* ''Animation/BoBoiBoy'': The titular hero has ElementalPowers, and each element has a personified form that he can turn into. [[LiteralSplitPersonality Multiple elementals can be summoned at a time]], typically three at a time via "Triple Split", and can later merge back to make the whole [=BoBoiBoy=] again. Initially, the longer he used his Triple Split, [[EquivalentExchange the more forgetful he became]], and therefore the elementals had to merge back as quickly as possible after splitting.
52	[[/folder]]
53
54	[[folder:Comic Books]]
55	* ComicBook/DeathsHeadII gained independence after the Minion cyborg assimilated the minds of 105 of the most deadly minds in the universe, only to have its last target (the original ComicBook/DeathsHead) take over its programming and form a gestalt personality.
56	* Crazy Jane of ''ComicBook/DoomPatrol'' had 64 distinct personalities when introduced, each with its own superpower. Over the course of her initial run she began integrating them. Two in particular, Baby Doll and Scarlet Harlot, merged to become Baby Harlot. (She was based on Truddi Chase and the Troops, who catalogued 92 people, never integrated, and despised the idea.)
57	* In ''ComicBook/ElfQuest'', Two-Edge's mind was split in two by Winnowill, [[spoiler:his ''mother'']]. He tries to use a troll vs. elf ''war'' to decide what he really is. [[note]]Significantly, the war is won by the elves AND their troll allies.[[/note]] Later, instead of running, Two-Edge allows Leetah to heal his fractured mind. His later appearances show him to still be a bit loopy, but with only one mind running the show.
58	* ''ComicBook/SpiderMan'':
59	** The Green Goblin has undergone this after his 1996 comeback, the Goblin previously veering between being an outright SplitPersonality of ComicBook/NormanOsborn, a psychotic break from reality and the power fantasy of an unstable CorruptCorporateExecutive who just won the SuperpowerLottery. Naturally, the amalgation of a mentally ill white collar criminal with his homicidal maniac alternate persona did not exactly make things better- the new Norman Osborn was a MagnificentBastard who developed particularly twisted views on his emnity with Spider-Man and graduated from millionaire industrialist to head of S.H.I.E.L.D. (because HumansAreMorons). Recently, the Goblin has shown signs of making a comeback, in the form of delusions and homicidal mania.
60	** Later, Osborn was purged of the Goblin formula entirely. While he's been BroughtDownToNormal, he sees the sudden lucidity as an advantage in crushing his enemies, and the "good" Norman that used to appear during his early bouts of amnesia is entirely absent.
61	* ''ComicBook/GreenLantern'': After transforming into Star Sapphire during the mid-80's due to not being able to cope with the extended absence of Hal Jordan, Carol Ferris split into two beings — Predator, which represented "the male side of her", and Carol herself, who was the normal "female side" that loved Hal. After Hal Jordan decided to quit the Green Lantern Corps, Predator kidnapped Carol Ferris and performed a Fusion Dance with her that changed them into Star Sapphire right before Hal's eyes. Later, though, Carol grew more stronger when she accepted the Star Sapphire ring willingly to the point that she regained control of herself in her Star Sapphire form.
62	* ''ComicBook/TheIncredibleHulk'': Doc Samson once pretended to have done this to the Hulk and Bruce Banner, via EpiphanyTherapy. But [[FailureIsTheOnlyOption eventually the change in premise became too much of a problem for the Hulk's title]], and the writers made use of the fact that Therapy Does Not Work That Way to establish that Samson had really just created a new, if more stable, alternate. [[CanonDiscontinuity Tossing out the fact that Doc Samson wasn't really in control of the process and didn't fully understand what was happening at the time.]] Since there are three "main" Hulk personalities (Savage Hulk, Child Hulk and Gray Hulk) and several secondary ones like Devil Hulk and the aforementioned Professor Hulk, it's a topic they have explored several times since, sometimes without including Banner in the merger at all.
63	* In the schoolgirl comic book ''Julie's Jungle Cousin'' Sue has two personalities: Jungle Sue, a gender-flipped Franchise/{{Tarzan}} who speaks YouNoTakeCandle, acts on instinct and is capable of daring physical feats; and Stuttering Sue, who speaks grammatical English with a stutter and is a physical klutz. By the end of the comic she has managed to integrate the two into one articulate, athletic personality.
64	* ''ComicBook/{{Exiles}}'': Morph and Proteus actually come to terms with being in each other's body and mind, respectively in Claremont's ''New Exiles'' Annual.
65	* ''ComicBook/{{Superman}}'':
66	** In ''ComicBook/AdventureComics #313: ''ComicBook/TheCondemnedLegionnaires'', an evil ComicBook/{{Supergirl}} is created when Kara gets exposed to red Kryptonite. At the end, though, Satan Girl is reabsorbed back into Kara.
67	** In ''ComicBook/Supergirl2005'' story arc ''ComicBook/GirlPower'', ComicBook/LexLuthor used a piece of black Kryptonite to create an evil Supergirl clone, and ComicBook/WonderWoman used her Lasso of Truth to merge both Karas back into a single being.
68	* ''ComicBook/WonderWoman1987'': The Greek Olympians split themselves to create the Roman pantheon a few millennia ago, with both developing distinct personalities and differences over the years, but in the face of ComicBook/{{Darkseid}} and the ComicBook/NewGods they remerge with their counterparts for more power with the Greek versions becoming more dominant but changed to reflect their Roman versions.
69	* ''ComicBook/XMen'': Professor X's wayward son Legion had his personalities integrated... into one guy who was ''far'' worse than his previous selves put together. The result was the ComicBook/{{Age of Apocalypse}}. Before, each of his selves only had access to one mutant power, and the good and neutral personalities acted as somewhat of a restraint on the evil one. The amalgamated version became an [[TheUnfettered utterly ruthless]] WellIntentionedExtremist with access to ''all'' of Legion's many powers ([[SuperpowerLottery which turned out to be stronger and more varied than anyone realized]]). Later, as the focus character of the X-Men: Legacy title, CharacterDevelopment allows him to do this without going off the rails.

72	[[folder:Fan Works]]
73	* ''Fanfic/BecomingPonies'': Fluttershy and Erica eventually perform this. As do one half of Twilight and Isaac.
74	* ''Fanfic/TheChaoticMasters'': [[spoiler: The purpose of the JourneyToTheCenterOfTheMind that the Collector takes Raven on is to merge with her [[AnthropomorphicPersonification emoticlones]], so that she can embrace her emotions and fully control her powers to the extent that Tirek can't use them to influence her.]]
75	* ''Fanfic/ChildOfTheStorm'': Bucky has three separate personalities -- Bucky Barnes, Steve's LovableRogue BestFriend and FriendlySniper; the Winter Soldier, the Red Room's implacable, hyper-efficient, and utterly ruthless SuperSoldier assassin; and James, who developed from the remnants of the former mixing with the latter. The first and last merge at the end of ''Child of the Storm'', with the Winter Soldier persona remaining as a SuperPoweredEvilSide that Bucky can unleash at will.
76	** In the sequel, [[spoiler: the Red Son persona]] merges with Harry -- though as only a few months worth of memories, without much of a mind of his own, it's dubious whether this totally qualifies. It doesn't change Harry's personality much, but it does make him a much more dangerous opponent, as [[spoiler: the Red Son]] was programmed with all sorts of combat skills.
77	* ''Fanfic/DanganronpaParadiseLost'': Midway through Chapter 5, [[spoiler:Shion Nanashi has a JourneyToTheCenterOfTheMind after being confronted with the fact that before she got amnesia, [[CanonCharacterAllAlong she used to be]] [[EnfantTerrible Monaca Towa]], which culminates in the two of them merging together. The resultant has both of their memories, answers to the name of Monaca, and has Shion's sense of righteousness]].
78	* ''Fanfic/FacingTheFutureSeries'' (a ''WesternAnimation/DannyPhantom''): In "Two For One", [[spoiler:at the end of the BattleInTheCenterOfTheMind where his ghost half wanted to do a SplitPersonalityTakeover, Danny managed to convince him that they were two sides of the same coin and that they needed each other, while apologizing for always seeing him as a burden. This resulted in his two halves merging and Danny getting control of his powerful [[SuperMode True Ghost Form]].]]
79	* ''Fanfic/{{Flinch}}'': Sheik is the embodiment of all of Zelda's repressed anger and violent desires. She's a PsychoForHire while Zelda is an ActualPacifist. Eventually, Zelda comes to terms with her aggression, merges Sheik, and [[spoiler:gives Samus a NoHoldsBarredBeatDown]].
80	* ''Fanfic/HaveFaith'': The tetralogy starts by establishing that Faith Lehane (from ''Series/BuffyTheVampireSlayer'') [[http://www.tthfanfic.org/Story-10602/Mediancat+April+10+1997.htm is actually an alternate personality]] for WesternAnimation/{{Daria}} Morgendorffer, produced to handle her rage over [[spoiler:her family's brutal murder]]. In [[http://www.tthfanfic.org/Story-11037/Mediancat+The+Sum+of+Their+Parts.htm the second story]], Daria and Faith wind up in a fight with [[spoiler:Glorificus who steals the mental energy maintaining their separation]]. Then [[spoiler:Willow pulls the same trick on Glory/Ben]]. [[spoiler:Daria's and Faith's minds work together to become "reason, backed by intuition... more than the sum of her parts," while Glory/Ben become completely paralysed by indecision: "less than the sum".]]
81	* ''Fanfic/TheImmortalGame'': Occurs to [[WesternAnimation/MyLittlePonyFriendshipIsMagic Twilight Sparkle]] near the latter end of the fic. Earlier in the story, the psychological trauma of being transformed into [[SuperpoweredEvilSide Nihilus]] had caused her mind to {{split\|Personality}} in two -- the dominant, [[ActualPacifist peaceful-to-a-fault]] Sparkle, and the more brutish Twilight. The two personalities spend quite some time [[TalkingToThemself arguing]], with Twilight pushing for a merge to restore themself to a full and equal mind, but Sparkle being too afraid that Twilight will pull a SplitPersonalityTakeover and be as [[HeWhoFightsMonsters monstrous as Nihilus was]]. Eventually, [[spoiler:[[BigBad Titan]] captures Sparkle and tortures her. The pain and desperation causes Sparkle to accept Twilight and fuse back with her, recreating the ''real'' Twilight Sparkle]]. Cue [[HesBack asskicking]].
82	* ''Fanfic/PonyPOVSeries'':
83	** Pops up in Pinkie Pie's reharmonizing chapter: [[spoiler:Angry Pie, a SplitPersonality representing Pinkie's anger, attempts a SplitPersonalityTakeover by absorbing Pinkie and her other personalities. In order to defeat her, Pinkie and Pinkamena fuse together, and the resulting being defeats and absorbs Angry, before fusing with the other personalities, restoring Pinkie's mind to its full state for the first time since she got her cutie mark.]]
84	** Happens again in the [[BadFuture Dark World]] timeline, [[spoiler:but differs from the main universe, in that Twilight has to [[JourneyToTheCenterOfTheMind enter her mind]] and talk her personalities into doing it, and she didn't have split personalities the entire time; she ''forced'' her mind back together and a number of factors resulted in it splitting again, allowing Twilight to help her put it back together ''right''.]]
85	* ''Fanfic/AShadowOfTheTitans'': According to [[EnemyWithin the Queen]], the longer that Jade spends in Shadowkhan form, the more this process will occur with the two of them, until eventually all that's left will be a being with the Queen's amorality, but with Jade's wit to keep her from being StupidEvil.
86	* ''Fanfic/ShadowsOverMeridian'': Part of the backstory for this RecursiveFanfiction of ''Fanfic/{{Kage}}'' is that Jade and her EnemyWithin, the Queen of the Shadowkhan, eventually decided they needed each other to survive, so they merged together to form a new personality with aspects of both. The main side effect of this is Jade gaining total control over the Shadowkhan tribes.
87	* ''Fanfic/TheWeaverOption'': The intense Callidus indoctrination and brainwashing apparently broke the mind of [[spoiler:Sophia Hess]], replacing her with the loyal apprentice Elena Kerrigan. However, on learning about Taylor's success, [[spoiler:Sophia]] resurfaced due to the sheer ''rage'' she felt. Elena's mind fought back but could not kill the original as that would destroy their soul; [[spoiler:the Emperor]] instead forced the two minds to merge into a single individual.
88	[[/folder]]
89
90	[[folder:Films -- Live-Action]]
91	* In ''Film/AvengersEndgame'', [[spoiler:we see that in the five-year TimeSkip after the Snap, [[ComicBook/TheIncredibleHulk Bruce Banner and the Hulk]] have reached an accord and accepted each other as part of the same being, so there is no longer a transition between the two. "Professor Hulk" retains the Hulk's size, strength and skin tone, but with Banner's brains and easygoing personality (and his wardrobe, [[NerdGlasses glasses]] and [[VocalDissonance gentle voice]]).]]
92	%%* ''Film/FightClub'': "You met me at a very strange time in my life."
93	* In ''Film/HellraiserIIIHellOnEarth'', [[spoiler:Pinhead Unbound and Elliot Spencer are merged back into the same being, which turns out to be Pinhead. Joey is given just enough opportunity to stab Pinhead and send him back to the Cenobite dimension.]]
94	* ''Film/MeMyselfAndIrene'': "I'm calling the shots from now on, Hank. I don't need you to fight my battles for me. If you can back down from something this important, you're nothing at all. YOU'RE NOTHING AT ALLLLLLLLLLLLLL!"
95	* The author and his cartoon character are merged in ''Film/{{Monkeybone}}''.
96	[[/folder]]
97
98	[[folder:Literature]]
99	* This happens to the main character at the end of the ''Literature/{{Hainish}}'' novel ''City of Illusions''.
100	* Dandra and Tetkashtai in the ''Dragon Below'' trilogy merged into one person at the end of the second book, combining Tetkashtai's psionic power and academic knowledge with Dandra's stubbornness and mental stability to form one psion much more powerful than the sum of her parts.
101	* Susannah Dean in ''Franchise/TheDarkTower''. She originally alternated between the personalities of Detta Walker (kind of psycho and seriously badass) and Odetta Holmes (a wonderful person, but often completely useless). Forcing them to notice each other led to them merging into Susannah, who keeps Detta's ferocity and Odetta's kindliness and feelings for Eddie. Still, the merge isn't perfect; at one point, Susannah has to let Detta take over again because she learned a lesson Odetta never did. [[spoiler:"Poetry-readin' bitch like her never had the time for a little ''ars mathematica''."]] Detta is also prone to resurfacing on her own occasionally, but when she does she is much less vicious than she was originally.
102	* Downplayed and reconstructed in ''Literature/TheWheelOfTime'': Rand Al'Thor suffered a long time clashing with his previous incarnation, psychotic and homicidal Lews Therin Telamon, and finally snapped. Eventually he [[spoiler: realized, that "voice of Lews Therin" was a way to manifest memories and experience from previous life, and accepted them as his own. Afterwards, he is still Rand, but much more stable, wiser and knowledgeable]].
103	* Happens to Tahiri Veila and her implanted Vong personality, Riina Kwaad, in ''[[Literature/NewJediOrder Force Heretic 3: Rebirth]]''. Riina, being a [[ProudWarriorRaceGuy Proud Warrior Race Girl]], had attempted a SplitPersonalityTakeover, but settled on the compromise when she realized that "killing" Tahiri would be disastrous for both of them.
104	* Creator/RobertSheckley has a story where a man underwent a treatment in his childhood by having his extra personalities siphoned away into artificial bodies. The story is about him searching for them all over the Solar System. [[spoiler: In the end, he collects them all, expecting them all to reintegrate into his, only to have all the parts, including himself, merge into a completely different persona]].
105	* The ''Literature/{{Animorphs}}'' [[StarfishCharacter starfish]] book, where Rachel morphs a starfish and ends up split in half, with both halves demorphing into a separate version of herself, ended with an Erek-mediated merging of the two halves.
106	* An unwanted merging happens in Robert Silverberg's short story "[[http://astraeasweb.net/plural/multiples-silverberg.html Multiples]]". TwentyMinutesIntoTheFuture being multiple is accepted as a variant normal experence, like being gay. A singlet woman voluntarily undergoes an experimental treatment to make her multiple. It works, but doesn't last.
107	* Daniel Keyes' novel ''Literature/TheFifthSally'', which is more or less based on [[https://archive.org/details/dissociationape02pringoog/page/n10 century-old cases of multiple personality]] plus his friendship/working relationship with [[https://en.wikipedia.org/wiki/Billy_Milligan Billy Milligan]], has everybody "fusing" together at the end, as does Creator/ShirleyJackson's novel ''The Birds' Nest'' and most of the popular-literature accounts, mostly written by doctors and ''not'' by the people experiencing the condition, which became popular in the 1970s and '80s. Many of these real-life multiples did not feel that integration was healing or a cure; [[Literature/WhenRabbitHowls some wrote their own stories]].
108	* ''Literature/RhythmOfWar'': For the past couple of books, Shallan Davar has had three semi-independent personalities: "Shallan" the artist and scholar, "Veil" the spy and street thief, and "Radiant" the duelist and noble. [[spoiler: At the climax of this book, we discover that Veil serves a second function: she protects Shallan from her worst memories, the things she dares not consider. When Shallan confronts the final set of memories she's been hiding, Veil integrates into Shallan and ceases to be an independent persona.]]
109	* This eventually happens with the Possessed (at least the ones who aren't complete psychopaths) and the people they've forcibly taken over in ''Literature/TheNightsDawnTrilogy''.
110	* ''Literature/TheImpossibleUs'': Geoffrey manages this with the aid of Nick's contextualization of his "displaced" memories.
111	[[/folder]]
112
113	[[folder:Live-Action TV]]
114	* ''Series/BuffyTheVampireSlayer'':
115	** In "The Replacement", Xander's personality is magically split into two bodies -- one being confident, competent Xander and the other being awkward, pathetic Xander -- and then merged again at the end.
116	** In the penultimate episode of Season 5, the barriers separating BigBad Glory from her [[SealedInsideAPersonShapedCan human vessel]], Ben, begin to break down. While they still inhabit Ben's body separately, their memories and personalities begin to merge together. This leads to Glory manifesting Ben's empathy and humanity and Ben inheriting Glory's [[ItsAllAboutMe selfishness and ruthlessness]], until they agree to work together.
117	* At the end of season 2 of ''Series/CloakAndDagger2018'', it's ambiguous whether this has happened to Bridget and Mayhem, or whether Mayhem's still in control but ''listening'' to Bridget in her head.
118	* ''Series/TheCrowdedRoom'': By the end of the series, Danny's undergone fusion therapy to merge his split personalities with him.
119	* Despite providing the picture, ''Series/{{Jekyll}}'' averts this. Even though Jackman and Hyde agree to work together, they retain their individual personalities and [[SuperpoweredEvilSide powers or lack of them]]. Their alliance is simply a case of switching voluntarily depending on which would be most useful at any time, and both of them agreeing to devote their respective talents towards the common goal of saving Jackman's family.
120	* ''Series/KamenRiderBuild'': The original identity of [[spoiler: Takumi Katsuragi]] resurfaces after [[ItMakesSenseInContext some demonic possesion shenanigans]] knocked out his SplitPersonality, but opts to merge with him after becoming convinced that it's the better solution, resulting in the latter's identity getting most of former's memories. He still hangs out in [[spoiler: Sento's]] mind to observe him afterwards and occassionally comes forth to talk to him in their shared mindspace.
121	* ''Series/TheSecretWorldOfAlexMack'' has Evil Alex and Good Alex merge after both of them had been separated.
122	* Season 3 of ''Series/StarTrekPicard'' has a downplayed example: Data and Lore's minds are essentially restored and put into a single positronic brain. When a BattleInTheCenterOfTheMind ensues for control over the shared body, Lore seemingly subsumes Data for a complete SplitPersonalityTakeover -- but because Lore deliberately assimilated Data's memories as trophies of his conquest, he effectively becomes Data but with some of Lore's personality (fortunately, not the malevolent aspects) mixed in.
123	* In the season 6 finale of ''Series/{{Supernatural}}'', Sam is stuck in a MentalWorld where his identity has split into three personalities: original Sam, soulless Sam, and the mentally broken Sam who's been [[FateWorseThanDeath tortured in Lucifer's cage]]. Finding his way out of there requires the other two to merge back into him. Unfortunately, soulless Sam is trying to murder original Sam to keep that from happening, and the broken Sam's memories are so [[GoMadFromTheRevelation traumatic]] that [[spoiler: Sam has to be admitted to a psychiatric hospital in season 7.]]

126	[[folder:Music]]
127	* "In Birdsong" by Music/EverythingEverythingBand describes the merging of the [[https://en.wikipedia.org/wiki/Bicameral_mentality bicameral mind]] as the origin of human consciousness.
128	* There's an unusual one at the climax of Music/TheWho's RockOpera ''Music/{{Quadrophenia}}''. In "The Rock," as Jimmy's [[MyLifeFlashedBeforeMyEyes life]] [[strike: flashes]] crawls before his eyes, the musical themes representing aspects of his personality merge into one. Hm? You say I can't possibly get all this information from an instrumental? You're right: [[AllThereInTheManual It's all there in the]] [[strike:manual]] liner notes.
129	* In another Rock Opera example, Music/GreenDay's ''Music/AmericanIdiot'' has this happening to St. Jimmy, the evil side of Jesus of Suburbia ("Jimmy died today; he blew his brains out into the bay").
130	* Music/{{Eminem}}'s [[KayfabeMusic kayfabe]] shows this happening over time. At the start of the story, Slim Shady [[SplitPersonalityTakeover takes control over the formerly positive]] ConsciousHipHop artist and wipes his original personality. Slim's personality forms a bleach-stain even on Eminem's increasing appearances in his discography, causing the line between the two to get blurred, until Marshall kills him in "When I'm Gone" due to him spreading into his personal life. Following [[CreatorBreakdown Eminem's drug addiction and depression nearly killing him]], Slim comes back from the dead BloodierAndGorier than ever on ''Relapse'', but is then PutOnABus for most of ''Recovery'' (having had a [[BoltOfDivineRetribution painful reminder]] to stay on his best behaviour, courtesy of God), while a now dark-haired Eminem airs sincere joy about his CreatorRecovery. The following album, ''The Marshall Mathers LP 2'', after Eminem was more comfortable in sobriety, shows a reblonded Eminem having found a comfortable medium with Slim, embracing Slim's exuberance and productive rage as well as Eminem's [[TheParagon Olympian compassion]]. The video for "The Monster" shows Slim locked up in Eminem's mind, but helping him out with his lyrics, while the song itself reminds us that they get along; the AlbumClosure tells us that the two of them are the same.

132
133	[[folder:Tabletop Games]]
134	* The goal of the Multiple Men in ''TabletopGame/BleakWorld''. Unlike most [[GoneHorriblyWrong Experiments]], the Multiple Men would rather live with their personalities than silence them and have various methods of getting along.
135	* ''TabletopGame/ChangelingTheLost'' has an EnemyWithout variant with regards to the fetch, an impostor made from a fragment of the changeling's soul to fill their place after they're taken by [[TheFairFolk the Gentry]]. Most changelings are just content to kill their fetch - either in an attempt to reclaim their life or destroy one of "their" tools - but it's possible for a changeling and a fetch to come to a deep, intricate understanding of how each one reflects aspects of the other's personality and being. If that happens, the changeling and fetch merge into one being, with the changeling's [[SanityMeter Clarity]] going up a level. Keep in mind this is a long, difficult process, and odds are other changelings won't look on you so kindly for attempting it...
136	* With the ubiquity of BrainUploading in ''TabletopGame/EclipsePhase'' it's not uncommon for people to make temporary copies or "forks" of themselves and later reintegrate the two. Unfortunately the longer they remain separate the more likely the chance of integration causing [[SanitySlippage stress]].
137	** Individuals who are willing to push the boundaries of transhuman science have attempted merging completely different egos together, though this almost always results in insanity.
138	* This is a central mechanic of the game, ''Vox'', where characters incorporate the voices in their head as a part of themselves they have 'forgotten,' growing closer to perfection each time.
139	[[/folder]]

141	[[folder:Video Games]]
142	* In ''VideoGame/BerwickSaga'', [[spoiler: Once recruited, Owen can switch to between "priest" and "dark priest" at will.]]
143	* It's not fully explained, but this happens in the Dimensional Vortexes in the DS re-release of ''VideoGame/ChronoTrigger''.
144	* As the Act 2 of ''VideoGame/Cyberpunk2077'' goes on, PlayerCharacter V starts affecting the mannerism of Johnny Silverhand, after being infected by a biochip containing his VirtualGhost, they're told it's [[YourDaysAreNumbered only a matter of weeks]] until their personality [[DeathOfPersonality gets completely overwritten by]] Silverhand's, and the rest of the game is them trying to find a way to stop it.
145	* In ''VideoGame/TheDarkness'' videogame, Jack Estacado manages to control the Darkness, a demon spirit that existed in his family since WWI, not through guns but by absorbing it into his own spirit. This allowed him to control the Darkness, but the Darkness reminded Jackie "with each life you take. I grow closer to owning your soul!" Guess what he has to do next to reach his Uncle Paulie?
146	** Even [[spoiler:Death]] is not enough to escape: Jackie [[spoiler:commits suicide]] after [[spoiler:Uncle Paulie kills his girlfriend before his eyes]] while he's being restrained by [[spoiler:the Darkness itself]], but comes back with the Darkness still possessing him.
147	* [[spoiler:Vergil's human half, V,]] does this with [[spoiler:his demonic counterpart, Urizen,]] in ''VideoGame/DevilMayCry5'', though they leave behind [[spoiler:Griffon, Shadow, and Nightmare, Nelo Angelo's emotional baggage]].
148	* ''VideoGame/Disgaea5'': A large part of Killia's backstory is his past [[spoiler: as Tyrant Overlord Killidia. Even after turning away from his old life and trying to change for the better after his defeat at Goldion's hands, his destructive urges keep rising back up throughout the story, largely thanks to his quest for revenge against Void Dark. Killia's BigEater habits were a means to suppress his Tyrant side, but they eventually stop being enough. It takes a return to his second-home Netherworld and another bout with Demon General Bloodis before Killia is finally able to accept his other self.]]
149	* The ''VideoGame/FalloutNewVegas'' [[DownloadableContent DLC]] ''Dead Money'' has Dog and God, a Nightkin with two personalities: the dumb, friendly, always-loyal, always-hungry [[MeaningfulName Dog]]; and the cold, calculating, intelligent, {{Jerkass}} ControlFreak [[JerkWithAHeartOfGold with a heart of gold]] [[MeaningfulName God]]. Essentially, they are the Id and Superego of one single personality, and eventually you have the option of merging the two personalities into one, or have either Dog or God [[SplitPersonalityTakeover take over completely]]. If you merge the two, Dog and God will finally put aside their differences for a brief moment to say thanks and goodbye to you before merging. The merged personality has no memories at all, but has a vague feeling like you've helped him, even though he doesn't know who the hell you are.
150	* In ''VideoGame/FatalFrameI'', Kirie ended up split into two parts -- one being the vengeful spirit possessed by the Malice and roaming the mansion, killing anyone that comes her way, and another, young version of herself that wants the other to be freed from the Malice and return to her original duty of keeping the Hellgate closed. The post-Final Boss scenes show the two forms merging again, and Kirie returns to her duty.
151	* ''Franchise/FinalFantasy'':
152	** Happens with [[spoiler:Kain]] and [[spoiler:[[EnemyWithout Dark Kain]]]] in ''VideoGame/FinalFantasyIVTheAfterYears''.
153	*** This happens to [[spoiler:Cecil]] as well. It turns out that [[spoiler:the [[CastingAShadow Dark Knight]] aspect of Cecil's personality that he cast away [[VideoGame/FinalFantasyIV seventeen years prior]] in order to accept the powers of a [[ThePaladin Paladin]] comes back to life and becomes Cecil's EnemyWithout, serving as a boss late in the game. Upon defeat, the Dark Knight [[BetaTestBaddie questions his identity]], causing Cecil to apologize for repressing this part of his life for so long and pull a YouAreNotAlone on his darker half. This event is crucial for [[HesBack rousing Cecil out of his]] HeroicBSOD (thus restoring his resolve and in-game stats), although Cecil doesn't regain his Dark Knight abilities (no, ''VideoGame/{{Dissidia\|FinalFantasy}}'' doesn't count... probably).]]
154	** In the final quest of ''[[VideoGame/FinalFantasyXIV Final Fantasy XIV: Shadowbringers]]'', [[spoiler:this happens to the Warrior of Light and the Warrior of Darkness shortly after realizing they're fragments of the same soul.]]
155	** In ''VideoGame/LightningReturnsFinalFantasyXIII'', [[spoiler:Lightning and Lumina merge once Lightning accepts the parts of herself she viewed as "weaknesses", which manifested as Lumina.]]
156	* A timid Shiro Fubuki from ''VideoGame/InazumaEleven 2'', merging with his HotBlooded alter-ego by the last two chapters.
157	* In ''Franchise/KingdomHearts'', someone whose heart is lost to darkness, but had above-average strength of will, can find that not only does their stolen heart become an instinct-driven [[TheHeartless Heartless]], but their leftover body gets back up and turns into an emotionless [[HumanoidAbomination Nobody]]. Killing or melding both of these will resurrect the original person. The Nobody can eventually grow a new heart with enough time and experiences, which makes their subhuman treatment in ''VideoGame/KingdomHeartsII'' rather morally dubious once it's revealed, but the resurrected human retains all of the Nobody's memories and merges any new heart with their own, so most of them are quite fine with it afterward. If you're Sora or Kairi, things get more complicated:
158	** Sora managed to keep his human form as a Heartless with some help from Kairi, and his Nobody Roxas didn't get any of his memories. This meant Roxas's appearance and eventual personality were completely different from Sora's, and while they ''do'' merge at first, Sora eventually questions the wisdom of the decision and seeks to resurrect Roxas as his own person. Sora doesn't know it, but he's ''also'' merged with Xion, an ArtificialHuman made out of memories stolen from him in a previous adventure, who also has her own personality. [[spoiler:Both of them permanently get new bodies towards the end of ''VideoGame/KingdomHeartsIII'']].
159	** Kairi and Naminé are in a similar boat: since Kairi literally [[IncorruptiblePurePureness cannot become a Heartless]], she's able to retain her body and memories when Naminé is born, leaving Naminé with nothing but the barest of existence to call her own. The pair eventually merge, [[spoiler:though this too is undone at the end of ''VideoGame/KingdomHeartsIII'']].
160	** [[EnemyWithout Vanitas]] tries to force this with Ventus at the climax of ''[[VideoGame/KingdomHeartsBirthBySleep Birth by Sleep]]'', which would cause TheEndOfTheWorldAsWeKnowIt if he succeeded. Ven eventually manages to break the merger at the cost of sending both halves into a ten-year-long coma, which they spend trapped inside Sora's heart. Combined with the previously-mentioned mergers, Sora's heart is quite the clown car by the time of ''[[VideoGame/KingdomHearts3DDreamDropDistance 3D]]'', with no less than four other hearts inside him. Xemnas even outright asks Sora how much of him can really be called ''him'' after merging with that many other people:
161	--->"The bits and bytes that have made up your life so far... can you say for sure that they are not just copies of someone else's?"
162	* In ''VideoGame/LaPucelle'', [[spoiler:Eclair]] confronts and merges with Dark [[spoiler:Eclair]] who is [[spoiler:her]] desire to be free and normal.
163	* Inverted in ''VideoGame/MassEffect3'' to [[spoiler: the geth, formerly a [[MindHive cooperative mass of programs,]] allowing them to become self-aware individuals, after the recently individualized Legion [[HeroicSacrifice merges himself with the Consensus.]]]]
164	* [[IAmWhatIAm Accepting one's Shadow self]] in ''VideoGame/Persona4'' transforms it into a Persona, which isn't quite merged but does act as a GuardianEntity instead of an EnemyWithout.
165	* This happens in the Good Ending of ''VideoGame/SilentHill1'', in which Cheryl Mason and Alessa Gillespie merge and are reincarnated into a new baby. In ''VideoGame/SilentHill3'', it is shown that Harry Mason has decided to care for the child, naming her Heather.
166	* In ''VideoGame/StarWarsTheOldRepublic'', the Sith Warrior fights an EnemyWithout of themselves in their class story on Tatooine. Depending on your current Force alignment, the shadow will taunt you for being either too Light or too Dark. You can bypass the fight entirely by agreeing with it and merging, but [[KarmaMeter you get points for the alignment opposite to yours as a result]].
167	* In the [[MultipleEndings normal and good endings]] of ''VideoGame/TalesOfSymphoniaDawnOfTheNewWorld'', [[spoiler:Ratatosk's personality comes to terms with the part of himself that is Emil and the two accept each other as parts of a whole.]]
168	* Not quite a merger, but in ''VideoGame/VampireTheMasqueradeBloodlines'', in the climactic dialog with [[spoiler: Jeanette/Therese]], with high enough stats you can persuade them to make amends and tolerate each other, in which case they bury the hatchet and peacefully coexist. Speaking with them later on reveals they're still separate entities, but apparently much more aware of each other [[spoiler:and the ensuing character is named 'Tourette' by the game.]]
169	* Fei in ''VideoGame/{{Xenogears}}'' merges with no less than three (possibly four, though that one was an EmptyShell) alternate personalities after convincing them to. This is remarkable since he wasn't the original, but ''the third'' personality.
170	* In ''Videogame/Psychonauts2'', Cassie O'Peia is suffering from a fragmented mind due to her mental archetypes being scattered. This culminates in a battle with the dominant Archetype, the [[ScaryLibrarian Librarian]], who represents her Superego. After her defeat, the Archetypes reconcile and combine to form a full version of Cassie.
171	-->'''Raz''': Are you... the real Cassie?
172	-->'''Cassie''': Hmm, not sure. But I'm sure she's in here somewhere.

177	* Occurs in [[spoiler:Ren's good ending]] in ''VisualNovel/DramaticalMurder'' with [[spoiler:Aoba and his SuperpoweredEvilSide, who he has come to realize isn't truly evil but lonely and acting out to get his attention]].
178	* Discussed [[spoiler: and averted]] in ''[[VisualNovel/ShallWeDateNinjaShadow Shall We Date?: Ninja Shadow]]'': [[spoiler: In Kagura's route, Saori hears of a medicine that could potentially help Kagura and his SplitPersonality, Homura, merge back together in peace. She goes through lots of danger to get it, but it turns out to be untested and she almost gets it ''force fed'' to her. After all of this is over, Kagura (and Homura) thank her for her efforts, but [[SplitPersonalityTeam they ultimately decide to co-exist and work together on their issues]].]]

181	[[folder:Web Animation]]
182	* The goal of the Meta (a gestalt entity of AIs created as [[LiteralSplitPersonality Literal Split Personalities]]) in ''WebAnimation/RedVsBlue: Reconstruction'' is to reconstruct the original Alpha [=AI=] from which they were split off. According to WordOfGod, the first AI in the Meta (Sigma) intended to rebuild the Alpha with itself as the leader.
183	* In ''WebAnimation/{{RWBY}}'', it's revealed that every incarnation of [[spoiler:the being currently known as Ozpin]] will eventually have their original personality fuse with those of the previous incarnations'. The current incarnation, [[spoiler:Oscar Pine]], still has his own identity separate from the collective [[spoiler:"Ozpin"]] personality, but he's accepted the eventuality that he'll ultimately be absorbed.
184	[[/folder]]
185
186	[[folder:Webcomics]]
187	* The ''Series/DoctorWho'' comic ''Webcomic/The10Doctors'' demonstrates a rare version of the trope. As the title suggests, the Doctor's [[TheNthDoctor regenerations 1 through 10]] all band together to save the universe. [[spoiler:At one point, Ten gets captured by the Daleks and is brainwashed into "Dalek Tor"]]. In order to defeat the programming there is a BattleInTheCenterOfTheMind where the Doctors all form one persona -- an amalgam of his multiple personalities.
188	* In ''Webcomic/{{Drowtales}}'', [[OurFairiesAreDifferent fae]], such as elves, are vulnerable to tainting, meaning that their "souls" have been infected by a demon. Usually, the demon will gradually consume the tainted victim, but it is also possible for the fae to merge their "soul" with the demon, leaving the fae's own personality dominant, making them immune to further DemonicPossession, and sometimes giving them access to special abilities originating from the demon.
189	* ''Webcomic/GunnerkriggCourt'': In Chapter 69, [[https://www.gunnerkrigg.com/?p=2070 Annie is split into two iterations of herself by Loup's meddling]] (one of which spent a couple of hours conversing with him in the Wood, while the other spent [[YearOutsideHourInside six months living in the Court with her father]]). In Chapter 79, Zimmy reunites them, [[https://www.gunnerkrigg.com/?p=2442 creating a single Annie with the memories of both iterations]].
190	* ''Webcomic/{{Homestuck}}''
191	** Inverted: [[spoiler: Gamzee Makara]] begins with the stable merged personality [[spoiler:when stoned]]. Then he [[spoiler:sobers up]], the personalities split, and both of the resulting personalities are AxCrazy.
192	** [[spoiler:When Jade Harley ascends to the God Tiers, she's merged with her dream self which had branched off into its own different personality, Jadesprite, for a time.]]
193	** This apparently was to be the destiny of [[spoiler:Calliope and Caliborn]] and it is implied to be part of the natural lifespan of their race, [[spoiler:the cherubs]]. Sadly [[spoiler:Caliborn managed to kill Calliope's dream self]] meaning that they will remain as fractured personalities forever.
194	* Attempted a few times by ''Webcomic/{{Jix}}'' and her alternate personalities Remula and Lamerix. The first time it seemed to work for a while, but broke down when she was cloned and Remula was seemingly transferred to the clone [[spoiler: they were actually copied]]. Another time a psychologist tried to get her personalities to destroy each other.
195	* ''Webcomic/KillSixBillionDemons'': Allison makes a DealWithTheDevil with Incubus in ''Seeker of Thrones'', giving her greater control of her [[CosmicKeystone Magus Key]] by becoming Incubus' emmisary. [[spoiler:During the caper on the Infinite Bank, this causes the Key-mastering parts of Allison -- her confident, sociopathic, power-hungry aspects -- to merge [[SplitPersonalityTakeover and take control of her body]] [[https://killsixbilliondemons.com/comic/seeker-of-thrones-7-84/ while the rest of Allison's consciousness is left divided and staring at the whole thing on the sidelines]]. After the power-hungry aspect leaves Cio to die Allison [[https://killsixbilliondemons.com/comic/seeker-of-thrones-9-103/ finally has enough and manages to come to a realization that all the Allisons in her head are her]], and goes on to confront and (literally) embrace the power-hungry aspect as another part of herself.]]
196	* This is one of the possible explanations for the ending of the Aiden and Brownwyn arc in ''Webcomic/{{Misfile}}''. It wasn't made terribly clear, but Rumisiel did force the Wraith-thing to into Bronwyn's psyche and told it to stay there, and Bronwyn did regain her affection for Aiden as a result.
197	* Mingmei Wu and Professor Sorgaz in ''Webcomic/TheWotch'', once Mingmei is made aware of her status as a [[GenderBender gender bent]] teacher dunked in the FountainOfYouth and the origional personality reappears. Perhaps a slight twist on this trope, as well; Mingmei is perfectly willing to go away so Professor Sorgaz can return to his normal life. It is ''Sorgaz'' who proposes merger, claiming she already has a better life than he ever did (He proposes merging the best of both worlds -- her friends, his bank account).

201	* ''WebVideo/EmpiresSMP'': While [[spoiler:"[[LiteralSplitPersonality Dark Sausage]]"]], the embodiment of [[spoiler:Sausage]] in his [[AmbitionIsEvil worst]], Corrupted state, was initially split from [[spoiler:Lord Sausage of Mythland]] in Season 1, [[spoiler:the [[AllLovingHero Protector of Sanctuary]]]], the Season 2 reincarnation of [[spoiler:Lord Sausage]], merges [[spoiler:Dark Sausage]] as part of his soul again after their battle. [[spoiler:Shelby]] is the only person to learn the two are, in fact, both different and the same person.
202	* Happens to [[spoiler:Sasha and Abby when Sasha dies while mentally linked with Abby]] in the Podcast/MetamorCity novel ''Making the Cut''.
203	* A [[https://anti-catharsis.tumblr.com/post/183557416601/can-i-just-go-ahead-and-say-how-great-the-writing fan commentary]] on the ''WesternAnimation/MiraculousLadybug'' episode "Oblivio" describes it in terms similar to this trope.
204	-->And despite neither of them having their memories they both still had their personalities and it was really nice to actually see their true selves come out without having any of their previous feelings, beliefs, or influence from their [[TransformationTrinket miraculous]] get in the way. They weren’t trying to be someone they weren’t.. Adrien wasn’t overly flirty, Marinette wasn’t clumsy or nervous... They were just there and they were them.

207	[[folder:Western Animation]]
208	* ''WesternAnimation/DuckTales2017'': In "The Split Sword of Swanstantein!", Lena discovers that logical Huey has mentally locked away his savage emotional side behind a door, calling him "The Duke of Making a Mess", and convinces him that he needs the inner strength of the Duke in order to defeat Steelbeak. While the Duke initially overpowers Huey's rational thinking, Huey finally shakes hands with the Duke, giving him the perfect balance of strength and logic to take down a thug ''three times his size'' without giving in to rage.
209	* ''WesternAnimation/OKKOLetsBeHeroes'': K.O. and Turbo K.O. can merge to form Perfect K.O. so long as one doesn't overpower the other. [[spoiler:The GrandFinale sees them merge permanently after K.O. accepts T.K.O. as being him instead of just a part of him, resulting in K.O.'s outfit becoming darker and him now having T.K.O.'s fang.]]
210	* ''WesternAnimation/RickAndMorty'': In the episode "Rest and Ricklaxation", Rick and Morty get split into "healthy" halves and "toxic" halves. Rick realizes they have to merge back to save the lives of their toxic halves, [[spoiler:but Morty refuses to do so and runs away. Eventually, Rick tracks him down and forcefully remerges him.]]
211	* ''WesternAnimation/TeenTitans2003'': In "Nevermore", Cyborg and Beast Boy accidentally enter Raven's mindscape, where the personifications of all her emotions live (i.e. Pink Raven is her happiness, Gray Raven is her shyness). When Trigon appears to menace her friends, the Ravens come together to defeat him.
212	* Mike in the ''WesternAnimation/TotalDrama All Stars'' finale, after hitting the ResetButton, not only loses his other personalities but also gains their abilities, except for Mal's.
213	* D.A.V.E. from ''WesternAnimation/TheBatman'' is an unusual variant in that he’s a robot programmed like this: take the personalities and skills of all of Gotham’s supervillains and squash them into one mind. His crimes have the traits of different villains on them, and when pressed on his origin rattles off the origins of Joker, Penguin, and Mr. Freeze while trying to recall his own.
