* ''UnitedStatesOfTara'': Alice, the "housewife" personality, reveals that she's jockeying to be the emergent personality if Tara ever reassumes therapy. This was followed by Bryce, Tara's alter based on her abuser, who reveals that he wants to "kill" Tara.

* ''UnitedStatesOfTara'': Alice, the "housewife" personality, reveals that she's jockeying to be the emergent personality if Tara ever reassumes therapy.

* Norman Osborn undergoes this in ''SpidermanTheAnimatedSeries''.

** The manga also suggests that [[spoiler: Legato Bluesummers]]'s original personality may have been pretty ordinary and that he used to have normal human needs, but that it soon got twisted beyond recognition by years of horrifying abuse in a small town plagued by criminality (and [[UnfortunateImplications paedophiliac homos]]) in the middle of nowhere-in-{{Mordor}} and [[spoiler: not even having a name, parents, or a past worth mentioning in his view]].

** Carnage called himself "I" as well, although in that case it was Cletus Kasady, who was already a psychotic killer, who took over the ''Symbiote's'' mind. The explanation that was recently given is that this was because the Red symbiote was just a baby when it first bonded with Kasady. Or, Kasady was just SO CRAZY, that he and the symbiote both wanted the same thing.

* During the ''{{SpiderMan}}'' storyline ''The Gauntlet'', [[spoiler: Curt Connors']] worst fears are realized when [[spoiler: he loses a battle of wills with the Lizard part of his psyche]]. [[spoiler: The Lizard kills and ''eats'' Curt's ''son'' Billy, and "Curt" essentially dies due to the trauma, leaving only The Lizard]].

* The above quote is a hearbreaking example of this trope from the 1986 remake of ''TheFly.'' Scientist Seth Brundle slowly transformed into a pathetic and diseased human-fly hybrid after accidentally fusing with said-insect in a teleporting experiment. At first the deformities were purely physical, as his human flesh warped and decayed into a "cocoon" under which the monster grew. Sadly, he also transformed on a mental level into an instinct based animal, unbound by compassion and morality. The love of Veronica, our heroine, was sadly not enough to stop his predictions from coming true...

* [[spoiler:{{Fight Club}}]]. Claimed by [[spoiler:Tyler Durden]] to be the evil plan all along.

* Happens to [[spoiler:Arnie Cunningham]] in ''Christine''.

* An episode of ''[[StargateSG1 Stargate SG-1]]'' had Daniel controlled by several diferent personalities that got in his head.
** ''StargateAtlantis'' has a similar episode where Rodney and a (female...) Marine wind up sharing his body. They each fight over control of the body, until it can't take their fighting anymore: if one of them doesn't give up and willingly disappear, both will die.

* ''{{Jekyll}}'': when [[EvilInc Klein & Utterson]] finally manage to capture Dr Jackman, they put him into a device that deletes one of the two personalities. Unfortunately for Jackman's wife, Hyde is the surviving personality. [[spoiler: However, when Mrs Jackman and her children are captured due to Hyde's immaturity, he ressurects his dead alter-ego and [[SplitPersonalityMerge merges]] with him, mixing Hyde's incredible strength with Jackman's maturity.]]

* Both the good and the evil ending of ''TheSuffering: Ties That Bind'' [[spoiler:results in either Torque and Blackmore wiping the other personality out completely.]]
* The bad ending of ''[[{{Manhunt}} Manhunt 2]]''- achieved by killing people as gruesomely as you can- has [[spoiler:Leo killing off Daniel's personality and becoming the sole resident of his body]].

* ''VampireTheMasqueradeBloodlines'' has a scene where, after being led along by the two, you finally confront [[spoiler:Jeanette and Therese Voermann -- wait, make that Tourette Voermann. One half of her face is done up in Therese's professional businesswoman style, while the other half is done up in Jeanette's slutty schoolgirl style, and the two sides speak in turns about wanting to kill the other]]. Depending on the dialogue you choose, either [[spoiler:Jeanette kills Therese, Therese kills Jeanette, or the two personalities decide to put aside their differences and coexist.]]
* Done very strangely in the ''{{Warcraft}}'' series; Arthas was a paladin who is corrupted by the Lich King, becomes his champion, then later merges with him, but then ''Arthas takes over the Lich King'', an entity of godlike mental power. A dark lord taken over by another dark lord [[spoiler:who is later revealed to be slightly less evil than everyone thought him to be]] when they became one dark lord.
* One of the main plot points of Riku's story in KingdomHeartsChainOfMemories and its remake is that Riku is fighting off the last of Ansem's darkness within his Heart. Several times he almost falls to it, and once he actually does, however how it happens depends on the version. In the original after completely dominating Lexaeus in their fight, the latter ''blows himself up'' in an attempt to drag the latter down into the Darkness, however in the nick of time he is able to resist. In the remake however, after a stalemate battle Riku lunges at Lexaeus to finish him off, only to be backhanded into the ''ceiling'' and passing out. Unconscious Riku's body is possessed by Ansem who then kills Lexaeus in ''one hit'' before Mickey appears and frees Riku.

* ''{{X-Men Evolution}}'', episode ''Sins of the Son''. Charles Xavier discovers he has a son in Scotland, David Haller, and goes to meet him, only for two other boys to enter the fray as well. These three boys (David, Ian, and the evil Lucas) are all parts of the same being. Xavier tries to help expunge Lucas, [[spoiler:but ends up locking away David, forever losing his son as Lucas goes off, never to be seen again (as the series was cancelled before this story could continue).]]

* In Animerica, this occurs to [[spoiler:Kiyone, explaining his MagnificentBastard actions in Season 2. The "evil" side attempts to do this again in the beginning of Season 3, but thankfully it gets destroyed for good this time.]]

* ''{{Inuyasha}}'' has Naraku trying part with Onigumo's human heart and soul which he eventually succeeds in doing it.

** They were right about each half of his face representing one of his personalities, they were just wrong about which side represented which. Oops.

** Carnage called himself "I" as well, although in that case it was Cletus Kassidy, who was already a psychotic killer, who took over the ''Symbiote's'' mind. The explanation that was recently given is that this was because the Red symbiote was just a baby when it first bonded with Kassidy. Or, Kassidy was just SO CRAZY, that he and the symbiote both wanted the same thing.

** Though During his time on Thunderbolts and Dark Reign, it seems the split personality explanation is back. Subverted in that Osborn is still an Evil jerk, the Goblin is just his darker side.

* During the ''{{Spiderman}}'' storyline ''The Gauntlet'', [[spoiler: Curt Connor's]] worst fears are realized when [[spoiler: he loses a battle of wills with the Lizard part of his psyche]]. [[spoiler: The Lizard kills and ''eats'' Curt's ''son'' Billy, and "Curt" essentially dies due to the trauma leaving only The Lizard]].

* Arguably what caused Brainwave's initial FaceHeelTurn after the end of ''Infinity Inc.'' About fifteen years later, [[EnemyWithin the new personality]] got possessed by [[PuppeteerParasite a ''third'', also villainous, personality]]. Eventually, when the third personality was defeated, it was heavily implied that the third personality ''ate'' the second one. In any case, [[HeelFaceTurn he got better]].

* [[InazumaEleven Fubuki Shiro]], who is taken over by Atsuya, his inner mind's high ego little brother. HeGetsBetter.

* Happens in "{{Artemis Fowl}}: The Lost Colony", when [[spoiler: after Artemis and Co. escape from the TimeCrash that's about to happen on Hybras, Qweffor (assisted by N°1) does it to the BigBad Abbot.]]

* ' He's also become more proactive and competent. At the moment it's actually unclear if it's really a split personality, or just him recovering from his acute amnesia.

** Carnage called himself "I" as well, although in that case it was Cletus Kassidy, who was already a psychotic killer, who took over the ''Symbiote's'' mind. The explanation that was recently given is that this was because the Red symbiote was just a baby when it first bonded with Kassidy.

* Happens to Il Palazzo of ''ExcelSaga''. Played straight in the anime, and a bit of a subversion in the manga, where, although the dialogue makes it quite clear there has been a hostile takeover, the only thing that really changes is his choice in clothing.

** Carnage called himself "I" as well, although in that case it was Cletus Kassidy, who was already a psychotic killer, who took over the ''Symbiote's'' mind.

** Though During his time on Thunderbolts nad Dark Reign, it seems the split personality explanation is back. Subverted in that Osborn is still an Evil jerk, the Goblin is just his darker side.

* ''InuYasha'' has Naraku trying part with Onigumo's human heart and soul which he eventually succeeds in doing it.

* Not one, but two different EXTREMELY bizarre variants occur in RedVsBlue Reconstruction: The first takes place in [[spoiler:the Meta, who is a freelancer taken over by several AI programs trying to reconstruct the Alpha]] and the second is related, only with [[spoiler:Church AKA the Alpha. He was tortured into several fragments. It was less of a "Takeover" and more of a division, but the results were similar.]] Could be argued that this happened to both Doc and [[spoiler:Flowers]] with the Omega AI since they had no control, just consciousness.

* Marik and Yami Marik from ''{[=~Yu-Gi-Oh!~=]''. The split personality is born when he kills his father. [[IGotBetter Marik gets his body back.]]

* Marik and Yami Marik from ''{{Yugioh}}''. The split personality is born when he kills his father. [[{{IGotBetter}} Marik gets his body back.]]

-->-- '''Seth Brundle''', desperately pleading his love to leave him before his final transformation into a giant fly in ''TheFly''.

If the takeover is incomplete, expect to see signs that the original is FightingFromTheInside. Antonym to SplitPersonalityMerge.

* ''VampireTheMasqueradeBloodlines'' has a scene where, after being led along by the two, you finally confront Jeanette and Therese Voermann -- wait, make that Jeanette/Therese Voermann. One half of her face is done up in Therese's professional businesswoman style, while the other half is done up in Jeanette's slutty schoolgirl style, and the two sides speak in turns about wanting to kill the other. Depending on the dialogue you choose, either Jeanette kills Therese, Therese kills Jeanette, or the two personalities decide to put aside their differences and merge.
