* 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 really cannot happen, 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.

* In ''Discworld/CarpeJugulum'', Nanny Ogg can tell the difference between Agnes and Perdita because Perdita's face is sharper.

* 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, and voice and clothing, but is still recognizable. 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, clothing, but also because [[spoiler:[[GenderBender he is a different gender than his good side]]]].

* 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 our 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.

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

* Buddy Love in the original version of ''Film/TheNuttyProfessor''.

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

* Cavendish from ''Manga/OnePiece'' is an [[Bishonen incredibly handsome]] man who transforms into an [[SuperpoweredEvilSide extremely quick, brutal murderer]] named Hakuba, who sports one hell of a {{Slasher Smile}} and {{Blank White Eyes}}. He also goes into a combination of both faces in what Bartolomeo calls a "Half N' Half" when Hakuba attempts a {{SplitPersonalityTakeover}}.

* 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.

* ''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 adds to the effect. It is best illustrated by Mandel's performance as the rude, obnoxious thief and gambler William Talbot.

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

* There is some very limited TruthInTelevision to this. Some people with actual DID (rare birds to begin with) have been documented to have alters with different handwriting, different handedness, different voice pitch, timbre, dialect, or speech mannerisms, or to walk or stand differently. Some alters may speak languages that other alters cannot. While physical changes (notably, eye colour — the most common SuspensionOfDisbelief Killer in portrayals of DID) cannot happen, these other behavioural changes can sometimes actually make the same body under two different alters difficult to immediately recognise as the same physical person.

* In ''{{Film/Supergirl}}'' Helen Slater 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.

* 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.

* Launch in ''Manga/DragonBall'' has a sweet, caring personality and a violent, aggressive personality that switch dominance when she sneezes. The sweet Launch is blue-haired, while aggressive Launch is blonde and has a HammerSpace machine gun.

* In the ''Series/DoctorWho'' episode ''[[DoctorWhoS33E12NightmareInSilver Nightmare in Silver]]'', there is no physical tell-tale indicating whether [[spoiler:Mr Clever]] or [[spoiler:the Doctor]] is in control, apart from the fact that the camera angle is oriented to the side of [[spoiler:his]] face with or without the Cyberman implants. The camera angle also focuses on the implants-free side when [[spoiler:Mr Clever]] tries pretending to be [[spoiler:the Doctor]] to trick Clara.

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

* [[IronLady Lady Une]] in ''Anime/GundamWing'' when she goes for LettingHerHairDown and [[TheGlassesGottaGo takes off her glasses]] becomes Saint Une, who has a much more gentle and peaceful personality. At the end she undergoes a SplitPersonalityMerge and keeps the unbound hair and no glasses look and the best parts of both personalities.
