Compare EnemyWithout, but the components are not necessarily enemies, and unlike in EnemyWithout none has any particular claim on being the "original" version. Also compare SelfDuplication, which is similar in appearance, if nothing else. Contrast FusionDance, where two or more beings become one being.

[[spoiler:While they eventually have to recombine back into one entity or 'die', while split the two personas are less violently destructive than the whole, allowing Jazz to give the Danny aspect of the split some psychological therapy. After she deduces that the older Danny was 'coping' with his grief and pain at the loss of his family by 'hiding' under Vlad's rage after the split, Jazz is able to help him acknowledge that he didn't always fail and encourage him to focus on the positives, with the result that the recombined ghost is less interested in pointless destruction]]. The sequel, "[[https://www.fanfiction.net/s/3541315/1/Indemnification Indemnification]]", sees [[spoiler:Dark Danny return to his future, where he occasionally interacts with the ghost of his deceased human side, the two acknowledging that the two aren't quite complete even if they recognise that they are now two distinct people]].

** Sandman had this happen to him once, in ''Peter Parker: Spider-Man'' by some plot. He got split into his core, his childhood self, his [[OppositeSexClone feminine side]], and unfortunately, his [[SuperPoweredEvilSide evil side]] in order to handwave why he stayed a crook.
** A ''ComicBook/TheAmazingSpiderManNickSpencer'' storyline saw Peter and Spider-Man split into separate entities, with Peter basically possessing all of the responsibility while Spider-Man only had his sense of humour, to the point that Spider-Man actually asked Peter who 'Uncle Ben' was and thought it was a good idea to reprogram the Tri-Sentinel as a means of transport, until Peter was able to reverse the process after confirming that the two would die if not brought back together.

** "[[Recap/RedDwarfSeasonVDemonsAndAngels Demons and Angels]]" features a triplication device, which creates a Good Ship with crew (who exist in the starship equivalent of CrystalSpiresAndTogas, and can even make Pot Noodles edible), an Evil Ship with crew (where Rimmer's H has fallen sideways and... yeah) and a Neutral Ship with crew (i.e., the original gang). The Neutral Ship duly explodes, and it requires a [[ReverseThePolarity polarity reversal]] to recreate it from the others.

** ''Series/MashinSentaiKiramager'': TheDragon Yodonna has the power to split entities into five clones, with each clone representing a different aspect of their personality. In one episode the green ranger Sena is affected by this attack. While four of them quickly rejoin into a single entity, her pessimistic aspect stays separate, thinking she is holding back the rest. However, it is soon learnt that the pessimistic aspect is actually causing Sena to rethink her plans, as the incomplete Sena is dangerously reckless because without her pessimism she can't imagine anything going wrong. [[spoiler: The EvilGenius Kurantula is also hit with this attack in order to fool the rangers into thinking they destroyed him. However, it is his evil aspect that gets destroyed, causing him to perform a HeelFaceTurn]]. Later in the series it is revealed that Emperor Yodon has multiple personalities that he can switch between at will. All of his extra personalities are destroyed before Yodon himself dies but his [[spoiler:Yodonna]] personality returns as a ghost independent from Yodon in two spin off episodes.

* ''Manga/SoulHunter'': Downplayed in Outenkun's case. While he have the power to split himself in several parts, his personality remain [[JerkAss rather consistent]] when he do so. But as he himself notice, each Outenkun is more focused on one part of his personality: His resentment towards Youzen and Tsuuten Kyoushu for the first one, taking revenge on Genshi Tenson for the second, and finding back the missing part of his soul for the the 3rd (and likely the "main" Outenkun if there is one).
** Played straight with TheReveal in he final arc that [[spoiler:Taikoubou]] and Outenkkun where initially the same being.

* The Triple Goddess: Maid, Mother and Crone
* One possible interpretation of the Christian Father, Son and Holy Spirit.

The squabble between the two led to the original H-Dial disappearing, which led to the Wizard creating a new pair of dials and trusting Chris King and Vicki Grant to use them while the Master created villains to try and take the dials fom Chris and Vicki.

'''Slipstream:''' ''Don't ask.''

* By ''Literature/TheHeroesOfOlympus'', it's revealed that most if not all of the Greek gods from [[Literature/PercyJacksonAndTheOlympians the previous series]] have Roman counterparts that differ from the original depending on what Roman ideals are placed on them. It's hinted that these counterparts are separate from each other and can combine. The renewed conflict between Camp Half-Blood and Camp Jupiter causes them to exhibit constant split personality disorder, one of the reasons why they don't assist the battle against the Giants directly (the other is because Olympus is sealed off by Zeus/Jupiter, so one one can).

* ''WesternAnimation/{{Centaurworld}}'' It turns out that the beast that would become [[BigBad The Nowhere King]] was created this way. [[spoiler:An Elktaur engineer who worked on the portal between the human world and Centaurworld fell in love with a human and decides to make himself human so she would love him back, so he separated his human half from his elk half, but his elk side was still intelligent and became jealous of his human half and wanted to merge back together. After the human half refused to merge back together with the elk half, the elk half started merging humans and animals together in an attempt to create a family for himself but repeated exposure to the magic he used warped him into a monster.]]

* ''Manga/OnePiece:'' [[spoiler:Dr. Vegapunk]] is revealed to have resorted to this, ''surgically'' rather than supernaturally, because he believed just a single lifetime wasn't anywhere near enough to get everything he wanted to achieve done. [[spoiler:That and he had more than enough brain for six people, which was both convenient and [[MyBrainIsBig cumbersome as hell]]]]. As a result, he's now six entirely different people working together.

* In ''Galzoo Island'', if you choose to make love to Nekomatamata and impregnate her, she will end up getting split into five children instead of one like all the other girls in the harem. Kusushi explains that eventually, the five children will combine back into one once Nekomatamata grows back to adulthood in a few days time.
