* ReformedButNotTamed: San, formerly one of the '''[[MultipleHeadCase three heads]]''' of King Ghidorah who has since been separated from Ghidorah's body and has merged with Dr. Graham to form a new two-headed creature in ''Fanfic/AbraxasHrodvitnon''. Although [[MoralityPet Vivienne's positive influence]] and being cut off from the other Ghidorah heads' evil influence leads San to [[HeelFaceTurn switch his moral alignment]] to fighting for Godzilla and humanity, San still retains a cruel streak towards anyone who personally hurts him and the ones he cares about past his patience threshold, and he still finds the thought of fighting with other monsters [[BloodKnight alluring]].
* VillainousIncest: ''Fanfic/AbraxasHrodvitnon'': Both Ghidorah's regenerating body and the autonomous [=MaNi=] version of '''[[MultipleHeadCase Ghidorah's right head]]''' are perfectly happy to use RapeIsASpecialKindOfEvil among other ColdBloodedTorture on Monster X to torment Vivienne into AxCrazy insanity, and are planning to use her as a monster BabyFactory. Although [[spoiler:Vivienne]] was born a human, Ghidorah's heads do still think that her transformation into [[spoiler:Monster X by San's severed head]] makes her both their sister and their daughter, and the fact she has [[spoiler:a "shed skin" version of San as her transformed body's second head doesn't deter [=MaNi=] at all from performing a subtextual violation of Monster X's body]].
* BigBrotherInstinct.FanWorks: ''Fanfic/AbraxasHrodvitnon'': This runs both ways with [[Characters/AbraxasHrodvitnonMonsterX Monster X]]'s two heads, [[TwoBeingsOneBody San and Vivienne Graham]], who consider each-other siblings due to MultipleHeadCase being Ghidorah's definition of siblinghood and due to bonding closely with each other, respectively. Anyone who actively and seriously messes with one of the two beings who compose Monster X is in for a world of agony and likely death from the other half. [[spoiler:Eventually, Vivienne somewhat extends her protectiveness of her San to his separate clone, San-2/Youngest Brother]].
* Characters.AShadowOfTheTitans: [Asuka-Tammy] two heads each with their own name and mind. Also upper bodies with extra arms. They are the same arachnid lower body.
* Characters.HearthstoneHeroesOfWarcraftAlternateHeroes: Omen has two heads, each with a distinct voice. They get along well for the most part, but the right head is more cunning and the left head is more aggressive.
* Characters.NickelodeonAllStarBrawl: Unlike ''Smash''[='s=] transforming duo characters, Cat and Dog are conjoined twins [[AHeadAtEachEnd connected via a long, stretchy body]] who simply swap positions rather than transforming in any capacity.
* Characters.PokemonGenerationIIChikoritaToGranbull: Girafarig has an extra head on its tail, which has its own simple brain and can act, perceive and attack separately from the main one. When it evolves, its two heads fuse together, and their brains are now directly connected through thick nerves.
* Characters.RollingWithDifficulty: HE-11 and Vice each have a distinct head, which switch out depending on who is in control.
* Characters.ShatteredGlassPrimeOthers: As is traditional for Quintesson Judges, Aquarius has five different faces, each with its own personality. Downplayed in that the faces usually agree on what to do, just not how or why they want to do it.
* Characters.StarVsTheForcesOfEvilTheMagicHighCommission: Rhombulus' snake hands have a mind of their own. In "Crystal Clear" they try to convince him that abducting Star isn't a good idea. Their origins are explained in ''Star and Marco's Guide to Mastering Every Dimension'' wherein Glossaryck turned Rhombulus' original limbs into "thoughtful alligators" in an effort to counteract the bruiser's innate savagery. It didn't quite take and the snakes grew to hate Glossaryck as much as Rhombulus did. When magic disappears, the snakes outlived Rhombulus, but seem to have been reduced to regular snakes intellect-wise.
* Characters.TheAquabats: Briefly dated one '''[[MultipleHeadCase head]]''' of a man eating Siren.
* Characters.UltramanEighty: Each of Fire-Draco's three heads has its own personality, appearance, and powers. In fact, when the monster was originally defeated long ago, the heads' souls reincarnated as three separate humans.
* Characters.VivaPinataTVShowMainCharacters: Teddington is a snob who likes opera (he also likes singing it, [[HollywoodToneDeaf unfortunately]]) and sad, melodramatic movies while Tina is a snarky, more fun-loving but still hot-headed {{Tomboy}} type. The two don't get along at all and barely ever go a minute without arguing.
* ComicBook.BabeDarlingOfTheHills: Oliver and Boliver, a two-headed member of the freakshow. They haven't spoken for a month after having an argument, to which Babe laments they "were such good friends".
* ComicBook.TopTen: Dispatcher Linda "Janus" Burnett, like the Roman god, has a face on the back of her head. "Front-Jan" and "Back-Jan" are distinct individuals (even with their own boyfriends) and spend a decent amount of the first series bickering and competing with each other. The events in ''Beyond'' get her to ResignInProtest and go back to her parents (who are two-faced like her) and she's replaced with a ''three''-faced woman named Tara.
* DarkAndTroubledPast.FanWorks: ''Fanfic/AbraxasHrodvitnon'': [[Characters/AbraxasHrodvitnonMonsterX San]], the former '''[[MultipleHeadCase left head]]''' of Ghidorah. Ghidorah as a whole is just as violent, depraved and sadistic in this story as it's ever been, but it has a pretty compelling FreudianExcuse which also applies to San: [[spoiler:San and his brothers were originally just wild animals on some long-gone alien world fighting for survival, until they were captured by [[AbusivePrecursors the Makers]], systematically [[BeingTorturedMakesYouEvil tortured into evil]], and transformed into a BioweaponBeast. Ghidorah [[TurnedAgainstTheirMasters turned against]] and exterminated the Makers in revenge, but [[TerribleTicking the Old Noise]] which the Makers had programmed into Ghidorah's heads as a "standing order" continued tormenting the three heads ceaselessly, constantly and insatiably demanding endless bloodshed and destruction,]] until any trace of goodness in Ichi/Eldest Brother and Ni/Elder Brother was irreversibly "torn apart and forgotten" and Ghidorah's three minds were moulded into the AxCrazy interstellar OmnicidalManiac we all know it as. What's more, before and after the three heads' corruption, San was and always remained the [[TokenGoodTeammate least actively malicious and hateful of the three, and the most curious about humanity and the other "little" lifeforms]] his brothers so hated, for which Ichi and Ni were very physically, verbally and emotionally abusive towards San, treating him like little more than dirt.
* Film.ThreeHeadedMonster: The titular monster, of course. The middle head appears to be the one who's in charge, while the left and right head would spend times bickering when things doesn't go their way.
* MeaningfulName.LiveActionFilms: In his [[Characters/MonsterVerseKingGhidorah MonsterVerse continuity incarnation]], his MultipleHeadCase three heads are named Ichi, Ni and San, meaning One, Two and Three in Japanese and denoting the order of most to least intelligent head. The "King" in his name also carries special relevance with this incarnation, as he's initially only referred to as Ghidorah, the implication being that he only gains the name ''King'' Ghidorah when he [[TyrantTakesTheHelm successfully usurps Godzilla's kingship over the other Titans for a time]].
* RedemptionEqualsDeath.FanWorks: ''Fanfic/AbraxasHrodvitnon'': In the finale, [[Characters/AbraxasHrodvitnonKingGhidorah King Ghidorah]]'s left head goes rogue against the other two, '''[[MultipleHeadCase eviler]]''' heads, and he dies helping the heroes to kill the three-headed dragon and put an end to their menace once more.
* WesternAnimation.DragonTales: But they're two entirely different individuals. [[FridgeLogic Of two entirely different sexes...]]
* WesternAnimation.MonstersInc1: Very briefly seen, after Sulley and Mike expose [[BigBadDuumvirate Randall and Mr. Waternoose]]'s plan to [[TheMenInBlack the CDA]]. A two-headed monster can be seen, the two heads exchanging glances with each other.




to:

* StayAheadOfThisIndex: MultipleHeadCase: A being with more than one head whose different heads don't get along well.
* AdaptationalSympathy.FanWorks: The expansion on San's (Ghidorah's left head's) and Ghidorah's general characterization and backstory gives the former even more sympathetic traits and redeeming qualities than he was presented with in [[Film/GodzillaKingOfTheMonsters2019 canon]], and the physical and auditory abuse he suffers '''[[MultipleHeadCase from Ghidorah's other two heads]]''' is ''not'' PlayedForLaughs here. The San head has been under chronic physical and verbal abuse from his brother heads whilst having absolutely no-one else to turn to for ''billions'' of years, which has in turn made San dependent, severely love-starved, and [[ItsAllMyFault prone to self-blame and self-loathing]]; [[spoiler:to say nothing of what he went through before all that with [[AbusivePrecursors the Makers]]]]. San also truly likes and cares for his MoralityPet Vivienne Graham, taking his new responsibilities as her brother head to heart after their fusion.
* Anime.ChibiGodzillaRaidsAgain: Each of Chibi Ghidorah's heads often contradicts the other and can erupts into fights (usually over food).
* Characters.DigimonGhostGameSupportingCast: Like other Reppamon, his tail is completely sapient, and the two are constantly at odds with one another. In this one's case, the tail wants to prove its strength by attacking things and doesn't care for civilian casualties, while the main body is constantly fighting it to prevent people from getting hurt.
* Characters.GoosebumpsHorrorLand: [The Menace] has a second head that he constantly argues with.
* Characters.WarhammerWarriorsOfChaos: When he consumed and was consumed by the Daemon, his head split into two down its length and transformed into two independent heads atop two long, snaking necks. His original personality occasionally takes control of one of these, leading to his two heads fighting with one another until the daemon resumes control.
* Podcast.TheFallenGods: Tuatha has a pet Cerberus-Yorkie whose three names (Susienka, Binggan, Keksi) all mean "biscuit" in Slovak, Mandarin, and Finnish respectively. They also disagree often, with one having opposite opinions from another and the third acting as a neutral party.
* TooDumbToLive.AnimatedFilms: In ''WesternAnimation/HerculesPureMagic'', Hercules mentions that the Hydra's middle head is immortal. '''[[MultipleHeadCase The other heads]]''' immediately become so jealous that they jump into a volcano to test this immortality, even though that would also kill ''them'' (and the immortal head is the only one who can ressurrect the other heads when they're destroyed).



* WesternAnimation.TeenageMutantNinjaTurtles2003: Triple Threat from ''Fast Forward'' has three heads: a [[RedIsViolent red brutish]] one, a yellow [[CloudCuckoolander crazy]] one, and a methodical blue one



[[folder:One power per head]]

[[/folder]]



* Characters.XenobladeChronicles3Moebius: When O and P Interlink, rather than one member dominating, the resulting fusion has two heads (one for O and one for P) and uses a StanceSystem to switch between a more bestial and a more humanoid stance where O or P is in control, respectively. As they're the only multi-headed Interlink in the whole game, this is played for BodyHorror and implies that their fusion isn't as "perfect" as they repeatedly claim it to be.



* TheQueenpin: WesternAnimation/KidCosmic has Boss Fiosa, the '''[[MultipleHeadCase two-headed]]''' alien crime lady of the Bagai Crime League. She was once the moll of the previous boss of the League, who was given two of the [[GreenRocks Cosmic Stones of Power]] by him as a gift. But she then used their power to [[KlingonPromotion kill him]] and take control of the organization for herself. '''(Putting this here because of the consistent use of single-person pronouns.)'''
* Characters.FutureCardBuddyfightDisaster: Actually averted. The heads don't act independently of each other. They even speak in unison.



* AttackOfTheMonsterAppendage: ''Series/BuffyTheVampireSlayer''. The MultipleHeadCase Hellmouth Demon seen in "[[Recap/BuffyTheVampireSlayerS1E12ProphecyGirl Prophecy Girl]]" and "[[Recap/BuffyTheVampireSlayerS3E13TheZeppo The Zeppo]]". '''(ZCE)'''

* Multiple people on one body = 24%
* Multiple heads that argue and bicker = 8%
* One personality trait per head = 2%
* Distinct entities are fused together = 2%
* The heads explicitly do not have distinct wills or personalities = 3%
* Unclear or not sufficient context = 51%
* Other = 1%
* ZCE = 9%

As an overall analysis:
* Insofar as the main definition requires that each had have a distinct personality and will, it's not being used like that. The largest category in both checks -- about half of the second -- is just "multiple heads are present" without any commentary one way or the other on their independence.
* The boundaries between "heads with distinct personalities" period, "heads with distinct personalities that don't get along and bicker", and "heads with distinct personalities that each have/embody a distinct personality trait" were rather fuzzy and required a number of arbitrary judgement calls. I am not confident about how well they work as trope distinctions. The third one might have potential if defined more strictly, but I'd be inclined to leave that on the maybe pile for some future day.
* The "one power per head" concept is useable, I think. It doesn't turn up a lot in these checks, but in a general reading of the main page a number of entries to that effect turn up.

My inclination is to cut and dismabiguate the main page, and then split off a new trope for "multiple heads have each their own personality and may or may not get along with each other" with a clearer name, another one for "each had has a distinct unique power", and a Useful Notes page for polycephaly.

There is some ambiguity in the description, laconic, playing with page, and index entries about whether this is supposed to be "heads with distinct personalities" period, "heads with distinct personalities that don't get along and bicker", or "heads with distinct personalities that each have/embody a distinct personality trait". In the interest of analysis, I'm going to group explicit examples of the latter two in their own categories.



* ''Anime/TheUltraman'': Cho, Jin and San are a trio of {{Sea Monster}}s who, because of pollution, ends up being mutated into a single three-headed entity, all three of their heads capable of interacting independently.
* The Creator/ECComics story "The Basket" from ''The Haunt of Fear'' features a two headed man who always keeps one of his heads covered with a basket so he can go in public. While one head is friendly the other is cruel and a murderer.



* ''WesternAnimation/{{Hercules}}'': The Hydra starts with a single head, but after Hercules decapitates it [[HydraProblem three more grow in its place]]. The heads glare at each other momentarily, and after Hercules keeps chopping off its heads the Hydra ends up with dozens of heads, wildly snapping and fighting each other over who gets to eat Hercules.
* ''Film/ThreeHeadedMonster'': The titular villain. The middle head is the one's that's in charge, while the left and right heads spends most of the film arguing with each other. Fittingly enough, the middle head is its sole weak spot -- removing it will kill the monster instantly.



* Music/InsaneClownPosse mention this in the song "Down with the Clown":
-->''What if I grew another fuckin' head?\\
And his name was violent... Ed?\\
And he'd headbutt me every time I cussed.\\
I would need two microphones when I bust.\\
Would you show me love even with another head?\\
Or would you be like: "FUCK YOU AND ED"!''



* ''Webcomic/{{Muertitos}}'': DJ Tonja doesn't so much have two heads as a second mouth on the back of her head, but the second mouth has its own personality, and often argues with the front face.



* "[[Recap/MyLittlePonyFriendshipIsMagicS4E17SomeponyToWatchOverMe Somepony to Watch over Me]]": The talking chimera has three heads, each with its own distinct personality: a tiger, a goat and a snake. They refer to one another as sisters, and spend much of their time arguing with one another. They can't ever agree on what to eat (besides pies) and the goat and tiger heads bicker about who's in charge.



* ''Fanfic/KaijuRevolution'': Each of King Ghidorah's three heads have an independent personality, the center head is dominant and the most well-coordinated, the right head is a BloodKnight who will lash out even against the center's wishes, the left head seems to be self-loathing due to its tendency to nip at his body in disgust.



* ''VideoGame/MutantFootballLeague'': Brickhead "Bricks" Mulligan, the color commentator, has a "mutant hobbit head" that lives on his shoulder: Bricks, Jr. Junior ''hates'' Bricks. Eerily, it's strongly implied he can somehow separate from Bricks's body and move around on his own; sometimes he asks Bricks to provide an alibi as to his whereabouts last night if his parole officer calls. At the absolute minimum, Junior is fully formed enough to be capable of both vomiting and urinating of his own accord. Usually [[UrineTrouble directly]] onto [[ButtMonkey Bricks]]. '''(This feels like it should be on ConjoinedTwins, if they physically separate some of the time.)'''

* MeaningfulName.LiveActionFilms: In his [[Characters/MonsterVerseKingGhidorah MonsterVerse continuity incarnation]], his MultipleHeadCase three heads are named Ichi, Ni and San, meaning One, Two and Three in Japanese and denoting the order of most to least intelligent head. The "King" in his name also carries special relevance with this incarnation, as he's initially only referred to as Ghidorah, the implication being that he only gains the name ''King'' Ghidorah when he [[TyrantTakesTheHelm successfully usurps Godzilla's kingship over the other Titans for a time]].
* Music.ProfessorElemental: EldritchLocation: The attic from the song of the same name changes with each visit, is ruled by King Rat and populated by a range of strange and malevolent beings.

* ScrewedByTheNetwork.LiveActionTV: In 1996, MTV created a sister network called [=M2=]. Later known as [=MTV2=], it was dedicated entirely to music to answer concerns over the main network's [[NetworkDecay shift in programming]]. After introducing the "'''[[MultipleHeadCase two-headed]]''' dog" logo in 2005, [[AdoredByTheNetwork hip-hop became the dominant genre]] and the channel more or less became "MTV with {{Hip Hop}} and {{Rock}} videos". When Viacom's 2017 restructuring plan went into effect, the network scrapped its remaining original programming, and eventually stopped airing its early morning music video blocks, leaving it with nothing but rerun fare.

* TabletopGame.{{Necromunda}}: Having two heads was one of the options for mutant Scavvies in the 1st and 2nd Edition versions of the game. The mutation gave the model a 180 degree field of vision and allowed them to [[GunsAkimbo fire two pistols at the same time]] as each head is able to aim and fire one of the guns independently.
* TooDumbToLive.AnimatedFilms: In ''WesternAnimation/HerculesPureMagic'', Hercules mentions that the Hydra's middle head is immortal.

Although [[MoralityPet Vivienne's positive influence]] and being cut off from the other Ghidorah heads' evil influence leads San to [[HeelFaceTurn switch his moral alignment]] to fighting for Godzilla and humanity, San still retains a cruel streak towards anyone who personally hurts him and the ones he cares about past his patience threshold, and he still finds the thought of fighting with other monsters [[BloodKnight alluring]].

Although [[spoiler:Vivienne]] was born a human, Ghidorah's heads do still think that her transformation into [[spoiler:Monster X by San's severed head]] makes her both their sister and their daughter, and the fact she has [[spoiler:a "shed skin" version of San as her transformed body's second head doesn't deter [=MaNi=] at all from performing a subtextual violation of Monster X's body]].

The San head has been under chronic physical and verbal abuse from his brother heads whilst having absolutely no-one else to turn to for ''billions'' of years, which has in turn made San dependent, severely love-starved, and [[ItsAllMyFault prone to self-blame and self-loathing]]; [[spoiler:to say nothing of what he went through before all that with [[AbusivePrecursors the Makers]]]].

Added DiffLines:

The description primarily emphasizes the concept of each head having its own distinct personality -- the main definition at the start is given as "Whenever a creature has two (or more) heads and the ability to talk (or at least displays sapience to some degree), each head will have its own distinct personality." The bulk of the description is given over to how these personalities might interact with one another, what sorts of personalities they might have, and how shared body control works out.

One two-sentence paragraph at the end brings up the possibility of each had having "a distinct power or attribute", such as specific keen senses or different {{Breath Weapon}}s.

Before checking through examples, I'm going to establish to methodological guidelines:
* Firstly, I'm assessing each example in a vacuum -- that is, I'm not strictly concerned with what the subject of an example is actually like assuming complete knowledge of them. I'm only going to consider what each specific write-up says or emphasizes, because I'm not trying to find all valid examples of a theoretic trope, I'm trying to find out how this one is used in practice.
* Second, I'm assuming that, ''without further context being provided'', the ability for one head to perform one action while another head performs another is not inherently a sign of distinct minds existing -- not any more than, say, being able to do different things with each hand means having two minds in control of them. Multitasking is a thing. There aren't a lot of examples where this is a relevant concern -- most either clearly establish the existence of multiple personalities or don't have anything like this happen -- but it does come up a few times.

The example list breaks down as such, checking fifty examples:

[[folder:Multiple people on one body]]
* King Ghidorah's three heads in ''Series/{{Godzilland}}'' sometimes bicker, such as in the episode where they fight over a cake at Godzilla's birthday party.
* ''Anime/TheUltraman'': Cho, Jin and San are a trio of {{Sea Monster}}s who, because of pollution, ends up being mutated into a single three-headed entity, all three of their heads capable of interacting independently.
* The Creator/ECComics story "The Basket" from ''The Haunt of Fear'' features a two headed man who always keeps one of his heads covered with a basket so he can go in public. While one head is friendly the other is cruel and a murderer.
* ''Fanfic/DuranAndKiyohimesOmakeTheater'': Kiyohime has six heads. They all have different personalities. Head #4 is noted as being the daredevil of the group. Also, each head insists on its own food bowl, which Natsuki complains about, pointing out they all share one stomach. And each has its own taste in music, as they have separate headphones and players for each one.
* ''WesternAnimation/{{Hercules}}'': The Hydra starts with a single head, but after Hercules decapitates it [[HydraProblem three more grow in its place]]. The heads glare at each other momentarily, and after Hercules keeps chopping off its heads the Hydra ends up with dozens of heads, wildly snapping and fighting each other over who gets to eat Hercules.
* ''Film/ThreeHeadedMonster'': The titular villain. The middle head is the one's that's in charge, while the left and right heads spends most of the film arguing with each other. Fittingly enough, the middle head is its sole weak spot -- removing it will kill the monster instantly.
* ''Franchise/StarWars'': This trope is deconstructed in a ''[=HoloNet=] News'' story in ''[[Franchise/StarWarsLegends Legends]]''. Said story features a Troig named [[https://starwars.fandom.com/wiki/Dwuirsintabb Dwuir and Tabb]], with the former wanting them to be surgically separated due to his "brother", according to him, being mentally ill and suicidal. Unfortunately, the process is complicated by the fact that the separation could kill Tabb, and Troig medical technology has not advanced far enough to do that safely, but at the same time, [[MortonsFork not separating them could endanger both of them]]. This ethical dilemma sparked controversy that lasted all the way from the Clone Wars into the New Republic.
* Music/InsaneClownPosse mention this in the song "Down with the Clown":
-->''What if I grew another fuckin' head?\\
And his name was violent... Ed?\\
And he'd headbutt me every time I cussed.\\
I would need two microphones when I bust.\\
Would you show me love even with another head?\\
Or would you be like: "FUCK YOU AND ED"!''
* ''Radio/JohnFinnemoresSouvenirProgramme'': The fifth series features a song by [[Myth/ClassicalMythology Cerberus himself]], voiced by all three of the male cast (Finnemore himself, Simon Kane, and Lawrie Llewyn), each head with its own personality, so Cerberus addresses itself as "we". The song is basically a SympathyForTheDevil song (though Cerberus is [[DarkIsNotEvil not exactly a "Devil"]] except to people who [[EverybodyHatesHades don't portray him correctly]]) in which Cerberus laments that people don't show the BigFriendlyDog some kindness and affection instead of just fighting him all the time.
* ''Franchise/{{Pokemon}}'': Exeggutor's three heads all think independently, though they never argue due to their psychic powers. Alolan Exeggutor has ''four'' heads due to the dopey looking one on its tail.
* ''VideoGame/{{Stonekeep}}'': The Ettin has two heads with very distinct personalities.
* ''VideoGame/{{Warcraft}}'': Blizzard actually had an April Fools joke about the ogres, claiming that two-headed ogres would be playable in ''World of Warcraft'' as a sort of cooperative character. That is to say, two players each control a head, and both control movement. This being an April Fools joke, they of course emphasized all the features that made this playstyle incredibly inconvenient. This actually becomes a BrickJoke in ''VideoGame/HeroesOfTheStorm'', as described below.
* ''Webcomic/{{Muertitos}}'': DJ Tonja doesn't so much have two heads as a second mouth on the back of her head, but the second mouth has its own personality, and often argues with the front face.
* ''WesternAnimation/TheJetsons'': In one episode, Elroy's scout troop has a camp-out on the moon and briefly encounters what seem to be a troop of aliens with two heads each. And the heads of one of the aliens talk to each other about having only one head being strange and scary.
* "[[Recap/MyLittlePonyFriendshipIsMagicS4E17SomeponyToWatchOverMe Somepony to Watch over Me]]": The talking chimera has three heads, each with its own distinct personality: a tiger, a goat and a snake. They refer to one another as sisters, and spend much of their time arguing with one another. They can't ever agree on what to eat (besides pies) and the goat and tiger heads bicker about who's in charge.
* ''WesternAnimation/TransformersCyberverse'': The conjoined Autobot twins Rack'n'Ruin come off as this. Another two-headed Cybertronian named Doublecrosser is introduced in the post-series movie ''The Immobilizers'', whose heads aren't above blaming one another when their actions incite the ire of their fellow Mercenaries.
* ''Fanfic/KaijuRevolution'': Each of King Ghidorah's three heads have an independent personality, the center head is dominant and the most well-coordinated, the right head is a BloodKnight who will lash out even against the center's wishes, the left head seems to be self-loathing due to its tendency to nip at his body in disgust.
* ''TabletopGame/BloodBowl'': The Two Heads mutation is a physical ability available to any player on a Chaos, Nurgle and Skaven team that gives them a bonus to their Dodge rolls. The Skaven are particularly fond of this mutation with their most famous Star Player, Tarsh Surehands, having a pair of heads. Unfortunately Tarsh strangled himself to death after his heads got into an argument about a missed pass during an important game.
* ''WesternAnimation/ToxicCrusaders'': Headbanger is a mutated freak with two heads who each control their side of the body. One head belongs to Dr. Bender, a hideous MadScientist; the other belongs to Fender, an oafish SurferDude delivery boy. The body itself is kinda lopsided since the surfer's half of the body is rippling with muscle, whereas the scientist's is shriveled and emaciated.
* ''VideoGame/DragonsDogma'' has the [[ClassicalChimera Chimera]], with its usual three heads of a lion, a goat and a snake. Each of the three heads can fight independently, with the Lion being a melee attacker, the Goat being a spellcaster and the Snake covering blind spots and using poison attacks. They can, however, be sent into a panic that causes the three heads to fight over control. If the Goat is killed before the Lion, the Chimera becomes more aggressive and starts pouncing aggressively around the battlefield, but if the Lion is killed before the Goat, the Chimera becomes more evasive, running away from the player and casting long-range spells.
* ''VideoGame/MutantFootballLeague'': Brickhead "Bricks" Mulligan, the color commentator, has a "mutant hobbit head" that lives on his shoulder: Bricks, Jr. Junior ''hates'' Bricks. Eerily, it's strongly implied he can somehow separate from Bricks's body and move around on his own; sometimes he asks Bricks to provide an alibi as to his whereabouts last night if his parole officer calls. At the absolute minimum, Junior is fully formed enough to be capable of both vomiting and urinating of his own accord. Usually [[UrineTrouble directly]] onto [[ButtMonkey Bricks]]. '''(This feels like it should be on ConjoinedTwins, if they physically separate some of the time.)'''

[[folder:One personality trait per head]]
* ''ComicBook/{{Supreme}}'': In one issue, Suprema encounters a demon with seven heads, each embodying one of the SevenDeadlySins. They don't get on with each other very well.
* ''Literature/JourneyToChaos'': The true form of [[spoiler: Kallen Selios]] is that of a four-headed chimera. Three of them (goat, lion and dragon) emerge from her neck and the fourth one (snake) comes out of her posterior as a tail. All of them represent different aspects of her personality and so they present different viewpoints. Thus they argue.
* ''VideoGame/{{Deltarune}}'': Clover, being based on the clubs playing card suit, is a three-headed... quadruped of some kind. One head is friendly, one is cranky and self-centered, and one is a ShrinkingViolet. They do agree on some things, though, and the trick to ending the fight with them is to get them talking about those subjects.
* ''WesternAnimation/DextersLaboratory'': During Dee Dee's DerailedFairyTale in "Deedeelocks and the Ness Monster", the three heads of the Ness Monster are the happy-go-lucky Silly Ness, the surly Grumpy Ness, and the narcoleptic Sleepy Ness.
* ''WesternAnimation/FamilyGuy'': In "[[Recap/FamilyGuyS8E1RoadToTheMultiverse Road to the Multiverse]]", one of the {{Alternate Universe}}s is a world where all the characters have two heads, one happy and one sad. Stewie's two-headed counterpart has no problems [[ScrewYourself kissing himself]].
* ''Webcomic/{{Spinnerette}}'': Minerva the [[HellHound Cerberus]] has three heads, each one with its own look and personality. The left head is the cute one, the right head is the brash, feisty one, and the middle head is the mature, moderate one. Interestingly, rather than being presented as three individuals sharing one body, it's more like Minerva is a single person who's thoughts are the same for all three heads, just filtered through different personality traits. According to her later on in the issue, the heads do not share thoughts (they have different personalities) but instead synchronize their memories during sleep. We see her heads talking to one another a few times in the book-only [[http://www.spinnyverse.com/comic/01-09-2012 Issue #9.]] They also wind up a bit distracted thanks to a HatePlague in [[https://www.spinnyverse.com/comic/11-21-2012 Issue #13]]. '''(Note: the description really goes back and forth over how distinct the minds are here.)'''

[[folder:One power per head]]
* ''VideoGame/MegaManZero1'': As a Mechaniloid based on the Orochi, the guard Orotic has eight heads, a pair each for FireIceLightning and NonElemental.
[[/folder]]

[[folder:Distinct entities are fused together]]
* ''VisualNovel/SlayThePrincess'': Tampering with the story causes AGlitchInTheMatrix to merge five different princesses together into a horrid mess. In their ending, they've gotten their act together and are considerably prettier, and choose to forgive you for turning them into this, since they no longer had to be alone.
* "[[Recap/TheSimpsonsS3E7TreehouseOfHorrorII Treehouse of Horror II]]": At the very end of "Homer's Nightmare", Mr. Burns' body is crushed, so he has his head surgically grafted to Homer's ample frame. Parodied in TheStinger with Homer complaining that this means he often has to cancel favorite activities in order to meet Mr. Burns' business obligations.
* ''WesternAnimation/TenkoAndTheGuardiansOfTheMagic'': The villains Janna and Jason can perform a FusionDance into a two-headed dragon, with each of them in control of one head.
* ''Literature/TalesOfMU'': Sara and Tara Leighton were fused together in [[http://www.talesofmu.com/story/other/two-heads-are-better a teleportation accident]] and now have their heads on one shared body.
* ''VideoGame/XenobladeChronicles3'': When Consuls O and P fail to have the heroes killed, they Interlink into a single, hideous, two-headed Moebius. While both heads have minds of their own, they seem to be coordinated and use a StanceSystem based on which one is calling the shots. [[spoiler:Unfortunately for them, one of the things they agree on, staying Interlinked for too long, results in their death via a localized Annihilation event,]] as O and P are both StupidEvil.
[[/folder]]

[[folder:The heads explicitly do not have distinct wills or personalities]]
* ''Literature/CarnivalInAFix'': The HauntedHouse attraction is run by a two-headed alien. Both heads are named Stan, so that is what they're collectively called.
* ''Franchise/{{Pokemon}}'': Girafarig has a second head on its tail. Downplayed in its case, since the tail-head has no higher brain functions, but it is stimulated by smell and is able to alert the other head and bite on its own. When it evolves into Farigiraf, the tail-head surrounds the main head and acts both as a helmet and for increased intelligence, as there are now neurons connecting their brains. Both Farigiraf's outer head and inner head cooperate perfectly.
[[/folder]]

[[folder:Unclear or not sufficient context]]
* ''Series/{{Angel}}'': A demon in Lorne's bar sings a duet of "Bye Bye Love", which you can do if you've got a second head in your chest.
* The poem "Us" by Creator/ShelSilverstein; something of an extreme example, as the accompanying drawing shows two faces stuck onto the ''same'' head.
* ''TabletopGame/DungeonsAndDragons'': In the template-heavy days of 3.5, there's "Multiheaded Creature", although it does put a reasonable limit on how many heads were added.
* ''TabletopGame/{{Pathfinder}}'': Magdh of the fae has three faces, [[TheHecateSisters mother, maiden, and crone]]. She is attended by a heirarchy of faerie dragons, amongst whom seniority is determined by the number of heads they have.
* In ''Toys/FlushForce'', there is the Gruesome Twosome team, made up of two-headed animals.
* ''VideoGame/IslandSaver'': The Mythic Wolf, Funny Flamingo and Mythic Turtle of Fantasy Island each have two heads.
* ''VideoGame/NinjaClowns'': Twisto is a three-headed [[MonsterClown hydra clown]].
* ''WebAnimation/{{Dreamscape}}'': In the flashback in "A Curse or a Blessing", Melinda's curse's dog form has two heads.

* ''WesternAnimation/{{Futurama}}'': We also see a dog with heads at both ends. The vet mentions that [[MindScrew one needs to take pills, the other needs a suppository]]. A goat with heads at both ends appears in another episode.
* ''Webcomic/TheOrderOfTheStick'': In FunnyBackgroundEvent, the succubus secretary of the three fiends tells them Miss Tiamat is holding on lines 2, 3, 5, 8 and 11. In this case, all five heads seem to be equally angry, given that all five roars are coming in through the phone. [[ReachingBetweenTheLines As do each of her five elemental breath weapons]]. '''(Note: Tiamat happens to be a valid example in-canon, but this specific write-up does not describe her as such.)'''
* Myth/SlavicMythology: The war and divination god of the island of Rügen, Svetovid, has four heads that represent the cardinal directions or the seasons. There is also the three-headed god Triglav[[note]]It is even in his ''name'': ''tri'' - three; ''glav'' - face, head.[[/note]], whose heads represent heaven, earth, and the underworld.
* ''VideoGame/MegaMan8'' has Search Man and his two heads. Wily thought that a two-headed robot master would be better for searching than a single-headed one.
* ''VideoGame/VivaPinata'' has the Twingersnap, a version of the Syrupent with AHeadAtEachEnd, acquired by whacking a Syrupent egg with the shovel the moment before it hatches; its waking animation has one head get up first and nudge the other awake. Doing the same thing to a Twingersnap egg gets you a Fourheads, which has, well, [[ExactlyWhatItSaysOnTheTin four heads]] -- three in front and one on the tail.

Crosswicks:
[[folder:Rough list]]
* AttackOfTheMonsterAppendage: ''Series/BuffyTheVampireSlayer''. The MultipleHeadCase Hellmouth Demon seen in "[[Recap/BuffyTheVampireSlayerS1E12ProphecyGirl Prophecy Girl]]" and "[[Recap/BuffyTheVampireSlayerS3E13TheZeppo The Zeppo]]".
* CannibalismSuperpower: ''TabletopGame/DungeonsAndDragons'': [[AllTrollsAreDifferent Dire trolls]] are a mutated form of troll that comes into being when a troll starts eating other trolls. This causes them to grow much larger and develop [[BodyHorror mutations]] such as [[MultiarmedAndDangerous extra limbs]], {{eyes|DoNotBelongThere}}, mouths, and '''[[MultipleHeadcase sometimes even entire heads]]''' growing from random places around their body. To further add on to this, they can graft parts from other trolls to themselves thanks to their [[HealingFactor regeneration]]. Each dire troll is thus a unique collection of grotesque horror. And, of course, they're much stronger and tougher than normal trolls, as well.
* DamnYouMuscleMemory: ''Fanfic/AbraxasHrodvitnon'': The [[Characters/AbraxasHrodvitnonMonsterX two-headed Kaiju]] formed of San (Ghidorah's [[WhiteSheep left]] [[MultipleHeadCase head]]) and Vivienne Graham merging together has a spar with Godzilla, during which Godzilla at one point propels them into the sky. The San half of them takes control of their arms and spreads them out wide on instinct, on account of him being formerly part of a flying dragon that had wings in place of arms (and likely also on account of the fact that the feelings of power and freedom that came with being able to fly are one of the only things about being part of Ghidorah that San misses).
* EquippableAlly: ''Webcomic/YetAnotherFantasyGamerComic'': A peculiar case with the Chimera, who is technically a single creature but also a MultipleHeadCase. The dragon head is the one in control of the BreathWeapon, but being a drooling idiot with no clue as to when, what or who he should incinerate, it is common for the lion head, in control of the body, to grab the dragon head and point him in the correct direction to use like a flamethrower.
* FracturedFairyTale: ''WesternAnimation/DextersLaboratory'' has "[=DeeDee=]-Locks and the Ness Monster"; Dexter's mom convinces (read: forces) him to read [=DeeDee=] a story because she's sick, which leads to Dexter reading her from a complicated science textbook. Bored to sleep, [=DeeDee=] takes over and makes up her own story, taking a bit of everything from old fairy tales with her own twists; such as three pigs made of Straw, Sticks, and Bricks, a Big Bad Wolf with the stature of [[TheNapoleon Napoleon]], and a '''[[MultipleHeadCase three-headed]]''' bag-pipe monster named the Ness Monster (each head with its own personality and PunnyName: Silly Ness, Grumpy Ness, and Sleepy Ness). Dexter interrupts halfway and {{lampshade|Hanging}}s the lack of story structure, but was ignored.
* HydraProblem: King Ghidorah from ''Film/GodzillaKingOfTheMonsters2019'' has an amazingly rapid healing factor, able to regenerate his severed left head in less than a minute, with that head's '''[[MultipleHeadCase individual personality intact]]''', no less. While he regrows only ''one'' head, fortunately, it's theorized that he can eventually regenerate from any severed piece of his body, with [[spoiler: his severed head being recovered in TheStinger implying he's not gone for good.]]
* LeakingCanOfEvil: ''Fanfic/AbraxasHrodvitnon'': While [[Characters/AbraxasHrodvitnon Ghidorah]] was still frozen in Antarctica, its '''[[MultipleHeadCase heads]]''' were partly conscious and aware of what was happening around their icy prison, and they were still able to exert a limited psychic and electromagnetic interference.
* MoralLuck: ''VideoGame/CastleForestIslandSea'', being about philosophy, discusses this trope, especially in conjunction with the '''[[MultipleHeadCase three-headed monster]]''' whose heads think independently. If two of them eat people and the third won't, is the third head as guilty as the others? It's connected to the same stomach!
* ObsessedWithFood: ''VideoGame/MonsterHunterGenerations'': The Nakarkos is a cuttlefish-like Elder Dragon that's responsible for ''[[PersonOfMassDestruction entire ecosystems]]'' disappearing into its beaked maw. However, unlike other HungryMenace cases such as the Deviljho, whose metabolism is so intense that it's constantly starving, the Nakarkos is different. It ''does'' use a few bones from its prey to cover its arms with, giving it the initial appearance of a MultipleHeadCase Elder Dragon, but mostly, it just [[ForTheEvulz doesn't have anything better to do]] than eat everything.
* OutOfCharacterAlert: ''Fanfic/AbraxasHrodvitnon'': In Chapter 13, when an enraged Vivienne and San rip [[UndeadAbomination the Many]]'s Skullcrawler host to shreds, they're unnerved by hearing [[BigBad Ghidorah]]'s '''[[MultipleHeadCase voices]]''' whisper "''[==]'''YESSSS'''[=SSSSssssss=]''" through the PsychicLink at their violent display in a soft, sensual tone that is uncharacteristic of them. [[spoiler:It's an early warning that Ghidorah has started to find Vivienne's episodes of temporary psychosis arousing, and has accordingly changed their plans for Vivienne to forcibly making her a monster BabyFactory]].
