History Main / SplitPersonalityMakeOver

* PlayedForLaughs with [[NiceGuy Tatsuya Yuuki]] of ''Anime/GundamBuildFighters:'' he flips his hair up in the same manner as the aforementioned Allelujah, to engage his "[[HotBlooded Gunpla Battler]]" side. He later uses the said hairstyle (coupled with CoolShades) to identify himself as [[CharClone Meijin Kawaguchi III.]]

* On ''Series/{{Haven}},'' each of the overlays has their own distinct personality and style, in part because the cycle repeats every 27 years, so most of them live in different time periods and because these [[FakeMemories personalities are based on real people]] who exist outside of Haven. In season 5, Mara, the original personality, [[SplitPersonalityTakeover is released]], and is noticeable for being much less [[TheUnfettered inhibited]] than Audrey, unbothered by nudity and very much TheGadfly. This is in addition to a different hairstyle/color and make-up style than Audrey usually wears.

* Allelujah Haptism from ''Anime/MobileSuitGundam00'' is a more subtle example; which personality is in control depends on which of his [[DualityMotif differently-colored eyes]] is hidden by his PeekABangs. Unusually for this trope, he's actually seen shifting his hair around in-universe when he changes personalities, rather than it happening automatically as a stylistic change.

* Mike from ''WesternAnimation/TotalDrama'', to different degrees depending on which personality is in control. [[GrumpyOldMan Chester]] is hunched over, has wrinkles and speaks in an older-sounding voice, [[ForeignExchangeStudent Svetlana]] has eyelashes, unique irises, and lipstick, and speaks in a female voice with a Russian accent, [[{{Jerkass}} Vito]] has slicked-back hair, sounds like he's from {{Joisey}} and doesn't wear a shirt (since Mike losing his shirt is what triggers the personality begin with) and [[AwesomeAussie Manitoba Smith]] has an Australian accent and a fedora (again, because Mike putting on a fedora is what triggers him). [[spoiler:[[TheSociopath Mal]] has PeekABangs, a [[EvilSoundsDeep deeper tone of voice]] (which also has [[VoiceOfTheLegion a reverb effect]] sometimes), and dark bags under his eyes, though he can hide everything but the occasional reverb when [[HydePlaysJekyll masquerading as Mike]].]]

* Not a split personality, but when WesternAnimation/{{Mulan}} is dressed as a [[SweetPollyOliver soldier]], she is drawn with no eyelid folds and a more angular jaw to make her look more masculine.

* ''[[VideoGame/DotHackGUGames .hack//G.U.'s]]'' [[spoiler:Sakubo]] lets you know who is in control by [[spoiler:her[[note]]Although Saku is a girl and Bo is male, the Sakubo character model is female[[/note]] hat, which changes which point is up, backpack, which changes color, eyes that switch from {{Tareme Eyes}} to {{Tsurime Eyes}}, and skirt which flares out or flattens. Her hair also gains a bit of a curve outward as Saku.]] Given that this is an MMORPG, this is hidden under the guise of [[spoiler:Saku and Bo being twin brother and sister.]]

* Motoko, the female protagonist of ''Manga/{{Change 123}}''. (Just look at the picture on the linked page!)

* In ''Series/DoomPatrol'', Kay/Jane's appearance alters slightly depending on which of her personalities is running the body in a way that reflects their appearance in [[MentalWorld the Underground]] (which often look completely different from the real-world body). This is frequently a hair or makeup change, but Hammerhead brings her tattoo and the Secretary acquires a pair of glasses from somewhere. Others are much less subtle - because Flaming Katy is always seen using her superpower that leaves her WreathedInFlames, any smaller effect she might theoretically be having is impossible to determine.

[[folder:Web Original]]
* In ''Literature/{{Twig}}'', when Sylvester's dangerous and unstable "Evette" persona takes over while he's emotionally withdrawn and not taking independent action, multiple characters observe she's far less effective at applying Sy's trademark TheSocialExpert skills...but also far more focused on causing people ''pain.'' Sy's friend Jamie recognizes that rather than a true SplitPersonality Evette is a manifestation of Sylvester's psychotic break exacerbated by the mind-altering Wyvern formula, and is able to bring Sylvester back to the surface.

* ''ComicBook/{{Superman}}'': Some of the artists who have drawn the Man of Steel, like Frank Quitely and Ed [=McGuiness=], have made a point of giving Clark and Superman slightly different appearances to help explain why so few people make the connection between the two of them. Quitely's version of Clark, for instance, has a noticeably hunched posture and badly combed hair (whereas his Superman has the usual spit curl). [=McGuiness=]' Superman has a [[ClintSquint perpetual squint]], while Clark's blue eyes are usually visible.

* There is some very limited TruthInTelevision to this. Some people with actual DID (rare birds to begin with) have been documented to have selves with different handwriting, different handedness, different voice pitch, timbre, dialect, or speech mannerisms, or to walk or stand differently. Some selves may speak languages that others cannot. While these "phenomena" have been exaggerated somewhat by overly impressed (singlet) psychiatrists, including changes in eye colour — the most common SuspensionOfDisbelief Killer in portrayals of DID -- which seems like it really cannot happen, but has been theorized as happening because of slight changes in tension of iris and/ or pupil. These other behavioural changes can sometimes actually make the same body under two different selves difficult to immediately recognise as the same physical person. [[Literature/WhenRabbitHowls Truddi Chase]] described herself and other multiples as capable of radically differing physical appearance depending on who was front, and there was nothing metaphysical about it; it's all based on posture, muscle tension or relaxation, emotional presentation and so on.

* Willem Defoe does a masterful job of this playing Norman Osborne/Green Goblin in the first ''Film/SpiderMan1'' movie. Using only facial expression, vocal changes, and body language, he becomes a completely different character, NightmareFuel incarnate.
* In ''{{Film/Supergirl}}'' Creator/HelenSlater gives Kara's secret identity Linda Lee a few subtle differences in behaviour and speaking, to distinguish her from Supergirl. The fact that she has dark brown hair while Supergirl has long blonde helps too.

* Sensui of ''Manga/YuYuHakusho'' has ''[[UpToEleven seven]]'' personalities. We meet three, and the visible difference is as impressive as it is subtle, having as much to do with mannerisms and speech patterns as it does visual cues.
* Pictured above: In ''Manga/SaintSeiya'', Gemini Saga has two personalities; when "Good Saga" is in control, he has blue hair and calm blue eyes. When "Evil Saga" is in control, he has gray hair and white eyes with bloodshot sclerae.

* In ''Manga/TodaysCerberus'', Cerberus' appearance will change depending on which personality is in control. The innocent Kuro has black pigtails, the hot-blooded Shirogane has long white hair, while the stoic Roze has pink hair and a mask over her face.
* Enigma from ''Manga/SketDance'' inverts this, as his personality changes when he does a "makeover" -- he's usually a soft-spoken ShrinkingViolet but becomes a boisterous LargeHam whenever he wears a mask.

* Sensui, the biggest single villain in ''Manga/YuYuHakusho'' (and the mangaka's favorite) has ''[[UpToEleven seven]]'' personalities. We meet three, and the visible difference is as impressive as it is subtle, having as much to do with mannerisms and speech patterns as it does visual cues.

* The two main human villains of the first season of ''Anime/{{Bakugan}}'', Masquerade and Hal-G, are alternate personalities of two humans that were changed by massive exposure to negative energy. Hal-G gains green skin when he is in control and also changes his eyes, hair, voice, and clothing, but is still recognizable. [[spoiler:It also turns out he is capable of taking control of his body while only changing his eyes (which he keeps closed) to fool people into thinking his good side is in control.]] Masquarade, however, is completely unrecognizable from his good side not only because he is always wearing a visor in addition changing his hair, voice, and clothing, but also because [[spoiler:[[GenderBender he is a different gender than his good side]]]].

* Pictured above: In ''Manga/SaintSeiya'', Gemini Saga has two personalities; when "Good Saga" is in control, he has [[YouGottaHaveBlueHair blue hair]] and calm blue eyes. When "Evil Saga" is in control, he has gray hair and white eyes with bloodshot sclerae.

* ''VideoGame/TwistedMetal'': The physical difference between Marcus Kane and his evil alter-ego Needles/Sweet Tooth is more obvious than most other examples, as Needles wears a [[MonsterClown scary clown mask]] and Marcus doesn't. In the reboot, this is explained by Sweet Tooth being a part of Marcus's personality [[SplitPersonalitySwitchTrigger only unleashed]] by wearing [[EvilMask the mask]].

* Therese Voerman from ''VideoGame/VampireTheMasqueradeBloodlines'' is a stiff Ventrue IceQueen in a business suit. Her "twin sister" Jeanette is a slutted-up Malkavian party girl. You find out they're sharing the same body when you reach the end of their storyline, and find Therese/Jeanette wearing Therese's clothes but with her makeup and hairstyle split between Therese's professional do and Jeanette's party girl do.

* In ''VideoGame/DragonAgeII'', this is the case with Anders. While [[KnightTemplar Justice]] is in control, he will have GlowingEyesOfDoom and a severe case of EvilSoundsDeep (the "evil" part may, however, be debatable), as well as a minor case of PowerEchoes.

* ''VisualNovel/DanganronpaTriggerHappyHavoc'' has [[spoiler:Touko Fukawa, an asocial, rude author]]. [[AfraidOfBlood At the sight of blood]], [[spoiler:Fukawa reveals her other persona, Genocider Syo, an infamous SerialKiller]]. The two are discernibly different in that [[spoiler: Genocider Syo]] has [[ScaryTeeth sharp teeth,]] [[RedEyesTakeWarning red eyes,]] and an OverlyLongTongue.
* ''VideoGame/LaytonBrothersMysteryRoom'': Alfendi's hair and posture change when [[spoiler:switching from Placid to Potty Prof.]] [[spoiler:Potty Prof]] has darker hair, a more hunched posture, and a [[{{SmugSnake}} smugger]] demeanor. [[spoiler:Placid Prof]] has lighter hair, stands up straight, and has a calmer, more subdued demeanor.

* There is no actual split personality involved, but Molossia from ''Webcomic/AxisPowersHetalia'' changes from his real NiceGuy personality to a {{Delinquent}} façade in seconds by changing his hairstyle and putting on a jacket and sunglasses when anyone but America enters his territory.

* ''VisualNovel/DanganronpaTriggerHappyHavoc'' has [[spoiler:Touko Fukawa, an asocial, rude author]]. [[AfraidOfBlood At the sight of blood]], [[spoiler:Fukawa reveals her other persona, Genocider Syo, an infamous SerialKiller]]. The two are discernibly different in that [[spoiler: Genocider Syo]] has [[ScaryTeeth sharp teeth,]][[RedEyesTakeWarning red eyes,]] and an OverlyLongTongue.

* ''VisualNovel/DanganronpaTriggerHappyHavoc'' has [[spoiler:Touko Fukawa, an asocial, rude author]]. [[AfraidOfBlood At the sight of blood]], [[spoiler:Fukawa reveals her other persona, Genocider Syo, an infamous SerialKiller]]. The two are discernibly different in that [[spoiler: Genocider Syo]] has [[RedEyesTakeWarning red eyes]] and an OverlyLongTongue.

* In Season 1 of ''Series/OnceUponATime'' Ginnifer Goodwin gives some very faint differences between her Storybrooke counterpart Mary Margaret and her Enchanted Forest counterpart Snow White. Mary Margaret is a little shyer and more soft-spoken, as well as being {{Adorkable}}. Snow meanwhile is more confident and prone to the occasional burst of sarcasm.

* Jamie from ''Anime/ZoidsNewCentury'' gains swept back hair and a bold, deep voice when he becomes [[RedBaron the Wild Eagle]] during air combat.

* Played straight with Zwei's two personalities Echo & Noise, from ''Manga/PandoraHearts'' . It even came as a shock to the main cast when they were revealed as being one and the same person. While Echo has dead eyes, free flowing hair, dresses in uniform, has a calm/stale posture and a voice that is generally gentle/weak, though devoid of emotion. When turning into Noise her eyes go wild with ecstasy, she braids her hair with an ornament, strips of all clothing (dressing up in a nightgown and blood-red cape), moves as if she was the star of a play and shouts/screams her words.

* In ''Manga/TodaysCerberus'', Cerberus' appearance will change depending on which personality is in control. The innocent Kuro has black pigtails, the hot blooded Shirogane has long white hair, while the stoic Roze has pink hair and a mask over her face.

[[spoiler:It also turns out he is capable of taking control of his body while only changing his eyes (which he keeps closed) to fool people into thinking his good side is in control.]] Masquarade however is completely unrecognizable from his good side not only because he is always wearing a visor in addition changing his hair, voice, and clothing, but also because [[spoiler:[[GenderBender he is a different gender than his good side]]]].

* Willem Defoe does a masterful job of this playing Norman Osborne/Green Goblin in the first ''Film/SpiderMan1'' movie. Using only facial expression, vocal changes and body language, he becomes a completely different character, NightmareFuel incarnate.

* Thendy Bravura (also known as another dozen names) in ''Literature/FelsicCurrent'' incurs very visible personality changes. Often, others can tell he's just "done it again" merely by witnessing his facials features melt into a completely different countenance, before he even speaks. Their mounting exasperation to these frequent incidences is usually the source of [[FunnySchizophrenia comedy]].
* The dark Cinderella adaptation ''Sunny Ella'' plays with this, as Ella sees the world (and herself) one way but the reality of the situation is much different. Ella sees herself as a beautiful fairy tale heroine with a lovely singing voice and a sunny disposition; in reality she is mute, scarred, unkempt and has violent tendencies.

* They comment on this extensively in the miniseries ''{{Series/Jekyll}}''. Hyde is slightly taller and thinner than Jackman, he has a slightly different hairline and jaw shape, and his eyes are jet black. Of course it's the same actor plus platform shoes and different tailoring/shooting angles, but the effect is subtle and present, and many viewers who may not even notice the prosthetic changes at the start of the series will immediately be able to identify which one of them is in control by the end, even without the vastly different body language and behaviour.
* ''Series/KamenRiderExAid'': Emu is kind hearted doctor who trips over himself a lot. His gamer self, ''M'', is confindent, brash with side of PsychopathicManchild. The changes become somewhat less obvious as Emu finds stable footing in his role as a doctor, which mends most of the differences, but not to the point of SplitPersonalityMerge.

* ''Series/TheOuterLimits1995'': In "Second Thoughts", a mentally impaired janitor named Karl Durand transfers the memories, experiences and personalities of four other men into his brain using a device built by Dr. Valerian, the first of those men. After the first two transfers, Karl begins to exhibit signs of something akin to multiple personality disorder as the other personalities briefly surface and take temporary control of his body. Karl's appearance does not change but Howie Mandel differentiates between the various personalities by changing his facial expressions, tone of voice and body language. Different camera angles as Karl converses with the other personalities add to the effect. It is best illustrated by Mandel's performance as the rude, obnoxious thief and gambler William Talbot.

* Not a split personality, but when Disney/{{Mulan}} is dressed as a [[SweetPollyOliver soldier]], she is drawn with no eyelid folds and a more angular jaw to make her look more masculine.
