->''Two heads? Who the heck needs 'em?\\
Two heads? How can you feed 'em?\\
Two heads! Day after day...\\
...It's drivin' me crazy in every way!''
-->-- '''Vanterviper''', ''WesternAnimation/{{Gallavants}}''

Whenever a creature has two (or more) heads and the ability to talk, each head will have its own distinct personality. In more comedic series, the heads will often argue with each other over which course of action to take.

SubTrope of ConjoinedTwins. Sometimes overlaps with BellyMouth or AHeadAtEachEnd.

!!Examples:

[[foldercontrol]]

[[folder:Anime & Manga]]
* Ebonwumon of ''Anime/DigimonTamers'', who has different accents in the dub.
* Kanan/Shuko/Junrei (collectively known as Honlon) from ''Manga/PetShopOfHorrors''. She's (they're?) a three-headed dragon with a different personality for each head. [[JustifiedTrope Justified]] in the manga's explanation of how dragons are born: the dragon's form and its personality are influenced by the person who cares for its egg, and thanks to unexpected circumstances, Honlon's egg was cared for by three very different people before it hatched.
* The Three Sisters in the first ''Manga/VampireHunterD'' novel and movie has the heads of three beautiful women and the body of some kind of silver dragony thing. The heads argue over which one of them gets to eat D.
* Rouge in ''Manga/RanmaOneHalf'', having fallen in the Spring of Drowned Asura, has three faces (all on different sides of the the same head) when she turns into her Goddess form. They bicker endlessly with one another, even yelling at each other to wake up if one of them is knocked out.
* The giant Judge Baskerville in ''Manga/OnePiece'' resembles the knight from ''Holy Grail'' and has one head that believes in punishment, one head that believes in mercy, and the center head which declares itself the most reasonable, but is really AxeCrazy. Subverted when it's revealed to be [[http://images1.wikia.nocookie.net/__cb20110514185624/onepiece/images/7/7e/3_Stooges.png three different people with very odd physiques sharing a shirt.]]
* Happens many times in ''Manga/FrankenFran''. In one particular variant, she stitched the salvageable remains of two clones that had just killed each other into one. We are then treated to a wide-headed, three-eyed, three-armed, three-legged human arguing with herself and beating herself up.
* ''Manga/InuYasha'' has the brothers Kinka and Ginka. Members of their species are born with two heads, with the stronger head killing and devouring the other early on to become a unique monster. Unfortunately, Kinka and Ginka have grown to be of equal strength, and spend all of their waking hours fighting each other violently, but to a stalemate. Note that they look more like two SnakePeople with their tails hopelessly imbricated rather than conjoined twins.
* One ''Manga/{{Bleach}}'' filler anime episode has a two-headed dog-like Hollow who was born from the spirits of two dead dogs. After nearly killing the little girl who owned one of the dogs in its life, one of the head attacked the other.

[[folder:Comic Books]]
* Double-Header of the [[ComicBook/{{Legion of Super-Heroes}} Legion of Substitute Heroes]] in Franchise/TheDCU -- pictured above. This is his whole "power" -- on his planet everyone undergoes mitosis at a certain age, but it happens over the course of some years. And his two heads don't even like each other, duh.
* In ''ComicBook/UltimateXMen'', Syndicate is the name for mutant conjoined twin brothers. They have two interlocked heads and three arms. They attempted to rob a bank, but Prof. Xavier stopped them. Afterwards, Xavier hired them to investigate the Hellfire club. Here's a [[http://syndicatetwins.tumblr.com fan page.]]
* ''ComicBook/GreenLantern'':
** One of the newest members of the Sinestro Corps is a two-headed alien. Both heads are psychotic killers but one likes killing people by ripping their bodies apart, while the other is disgusted by such crude methods and prefers more subtle methods of killing. They fight over who should control the Sinestro Corps power ring after they get it. And later, when the Green Lanterns assigned to tracking down and capturing the Sinestro Corps rings find some of their handiwork, the fact some of the bodies have been torn apart violently while others have been killed by precise controlled blasts hints that they are still fighting over control of the ring.
** There's also Maash, who has three heads (stacked vertically), the topmost being an innocent man and the bottom two both being cruel psychopaths.
* A four-headed, multi-limbed creature formed from the remains of four teenage boys is sent to kill John Constantine in one issue of ''ComicBook/{{Hellblazer}}''. He notices the different tattoos on each side of the body, from opposing football teams (each pair of boys had a different favorite team) and tricks them into arguing with themselves long enough for him to escape while they rip themself (themselves?) to pieces.
* Hindrance and Perfidia from ''ComicBook/MeatCake'' comics. Although it's not sure if they're siamese twins... They argue constantly, though.
* ''ComicBook/{{Supreme}}'':
** Baxter Frunnt... sort of. He's got one ''head'' so to speak, but it's got two bodies and personalities and faces to control, since his back is the other guy's front.
** 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.
* Divangelic in ''ComicBook/{{Empowered}}'' certainly looks like the two halves would have contrasting personalities, since one of them dresses as a [[HornyDevils sexy demoness]] and the other as an angel; she was always just a background character, though, so we never get to see them talk.
* Bi-Beast, an ''ComicBook/IncredibleHulk'' foe. But he's an android, so yeah.
* 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.
[[/folder]]

[[folder:Comic Strips]]
* George and Tail, recurring characters from the marginal comic strip of ''Cricket'' magazine, are the independently-sentient head and tail of one earthworm.
[[/folder]]

[[folder:Fan Works]]
* ''[[FanFic/RealityChecksNyxverse Nyx's Family]]'': [[spoiler:Garble, after eating way too many Fire Opals, grows huge and sprouts two extra heads, both of which have their own minds. Some time after the battle is over, it's revealed that dragons are not meant to have multiple heads, so his own physiology and self-healing properties will cause him to gradually split into three dragons, a slow, laborious and incredibly painful process that will take at least a year or longer to complete. Garble isn't very happy about this.]]
[[/folder]]

[[folder:Films -- Animation]]
* Devon and Cornwall, the two-headed dragon in the animated film ''WesternAnimation/QuestForCamelot''. They/he can't fly unless both heads can agree, which isn't often.
* The Mayor of Halloween Town from ''WesternAnimation/TheNightmareBeforeChristmas'', for some reason, actually has a smiling face on one side of his head, and a frowning one on the other. He ''is'' a politician, so it would be obvious that he'd be [[VisualPun two-faced]].
* Chunk from ''WesternAnimation/ToyStory3'' has a face that can flip between a smiling one and a frowning one by pressing a button on top of his head. During most of the movie, Chunk will always show his frowning face to show his affiliation to [[spoiler:Lotso]], but at the end of the film due to [[spoiler:Lotso]] being removed from the daycare center, Chunk actually now decided to show his smiling face.
* The Vanterviper's heads in ''WesternAnimation/{{Gallavants}}'' not only bicker, [[http://www.youtube.com/watch?v=enLAYqIrqto they also sing about their woeful plight.]]
-->'''Vanterviper:''' Oh, I will cry, 'till the day I die,\\
Two heads ''ain't better that one!''
* {{Orochi}} in ''The Little Prince and the Eight-Headed Dragon'', whose heads frequently fight-over vats of wine, over who gets to eat Prince Susano, and in fact, two of the last three heads bite each other off.
* Bad Cop/Good Cop from ''WesternAnimation/TheLEGOMovie'' doesn't have two heads, but two faces. Each with drastically different personalities.
* ''WesternAnimation/MonstersUniversity'' has Terry and Terri, members of the Oozma Kappa fraternity. They bicker from time to time but are also shown to share genuine care between each other.
[[/folder]]

[[folder:Films -- Live-Action]]
* The Three-Headed knight from ''Film/MontyPythonAndTheHolyGrail''. They first argue whether to kill the Sir Robin, then bitch about each other, and then disagree on what to do ''after'' killing him, giving him the time to bravely run away.
* Fode and Beed, the two-headed announcer from ''Film/ThePhantomMenace'', though the only clue to the differing personalities is that each head speaks a different language. To be fair, there are two main languages on Tatooine: Galactic Basic and Huttese. Some people can't understand Basic but do understand Huttese, and vice versa. That particular announcer was chosen because he could easily and fluently speak both at the same time.
* Averted with King Ghidorah from the ''Franchise/{{Godzilla}}'' franchise. His three heads don't seem to have any distinct personalities from one another.
* Scrad & Charlie from ''Film/MenInBlack 2''.
* Classic B-movie ''The Thing with Two Heads'' plays this seriously. [[{{Narm}} Or at least they try to.]]
* In ''Film/SpiderMan2'', the four tentacles of Dr. Octopus have a distinct personality from Octavius himself.
* In ''Film/TheHitchhikersGuideToTheGalaxy'' TheMovie, Zaphod Beeblebrox's second head is retractable and came out from ''under the other head''. It is eventually removed and used for collateral in exchange for the coordinates to Magrathea. Zaphod wasn't pleased, but it was just fine with everyone else, since the head was nasty, abusive, obnoxious and wouldn't be missed. Unfortunately, this greatly reduced his intelligence. Which, this being Zaphod, is saying quite a bit!
* One of the bug-like creatures in ''Film/{{Evolution}}'' has a head on each end of its body, with an extensible tongue in each. The way it walks suggests that both ends are independently trying to steer its multiple legs.
* If you watch carefully Fluffy the three-headed dog from ''Literature/HarryPotterAndThePhilosophersStone'' you can see that one head is paranoidly alert, one is lazy smart-aleck, and the third is a {{Cloudcuckoolander}}.
* The two-headed Makhai from ''Film/WrathOfTheTitans''.
* The main antagonist in ''Film/JackTheGiantSlayer'' is a two-headed giant named Fallon. The main head is in the normal, above the neck position and does all the talking. The second head is attached to his right shoulder. It's much smaller and [[TheUnintelligible much less intelligent.]] Despite all this, the two heads seem to get along just fine.
* The three-headed Tusseladd, the first troll encountered in ''[[Film/TheTrollHunter Trolljegeren]]''. Only the center head actually has a brain or eyes; the other heads grow just to hone the creature's sense of smell with additional noses.
[[/folder]]

[[folder:Literature]]
* Joe-Jim the two-headed mutant from the Creator/RobertAHeinlein novel ''Universe'' is one of the earliest modern types, and probably the first to be specifically described as a mutant
* ''Literature/TheHitchhikersGuideToTheGalaxy'':
** Zaphod Beeblebrox fluctuates between being one and two people, according to the RuleOfFunny. He operates as a unit most of the time, and only talks to himself when it's plot-appropriate. However, he can get hit on one head and knocked out, only for the other head to say, "What was that noise?"
** In ''Literature/AndAnotherThing'' (a sixth ''Hitchhiker'' book, planned by Douglas Adams and written by Eoin Colfer with Adams' notes and the blessing of the Adams estate), the left head has been surgically removed and cyborged into the Heart of Gold to run it better. It has a completely different personality from the Zaphod of the previous five books; a straight-laced accountant type who detests the excesses of the lifestyle he was forced to live as part of the Zaphod unit. Evidently it's entirely normal for Betelgeuse Five-icans; each head has a distinct personality, but one head will have the "dominant" personality and the other head's personality will be suppressed unless similarly removed.
* Runespoors, a species of magic snake from the ''Literature/HarryPotter'' background book ''Literature/FantasticBeastsAndWhereToFindThem''. Each of the three heads has a different personality. The left head is the planner, the center head is the dreamer, and the right head is always a CausticCritic, so the middle and left heads often team up to bite it off.
* The Brothers John from ''Literature/{{Abarat}}''. And yes, one of them is a {{Jerkass}} who always bickers with the others. [[spoiler:Creator/CliveBarker has stated that he intends to give them similarly conjoined love interests in a later volume.]]
* The Pierson's Puppeteers in Creator/LarryNiven's ''KnownSpace'' universe both play this straight and subvert it in that they have two heads, but the brain is in the central body.
* The brothers in ''First Person Plural'' by Andrew Beierle are dicephalus conjoined twins (two heads, one body). One brother is gay and the other is straight.
* The ''Literature/DoctorDolittle'' series features the Pushme Pullyu, a two-headed antelope.
* In one of Creator/GKChesterton's story, after several knights have failed to kill a one-headed giant, Red Legs kills a two-headed one because it's too busy quarreling to notice his approach.
* Zassaliss, Harssacss, and Sesstra of the ''Literature/{{Redwall}}'' book ''Triss'' weren't born conjoined, but a mace and chain thrown by the fighter who killed their mother bound their bodies together when they were little. Since they're snakes and therefore have no hands with which to untie it, they're permanently stuck. Zassaliss, the oldest of the triplets, took charge and bullied the other two into learning to coordinate with his movements. One really feels sorry for Sesstra, the only female...
* Shows up twice in ''Literature/ACanticleForLeibowitz'', and is an important plot point both times. The two-headed mutant who [[spoiler: kills Brother Francis]] doesn't display two personalities, but conclusively ends the first section. Rachel's evolution in the third section is played as the return of a sinless being to earth, highlighting the book's theme of history being cyclical.

[[folder:Live-Action TV]]
* In the fairy tale episode of ''Series/{{Scrubs}}'', an inseparable couple is described as a two-headed monster.
* In a dream sequence in ''Series/ILoveLucy'', Lucy imagines her neighbors Fred and Ethel as a bickering two-headed dragon.
* The ''Series/WhoseLineIsItAnyway'' game "Three-headed Broadway Star" has three players join together and sing a fictional Broadway song, one word per head. [[CrowningMomentOfFunny This commonly leads to non-sequitur mishaps.]]
* ''Series/{{Lexx}}'': Robot head 790 has himself sewn to the shoulder of a largely mindless cyborg drone, with whose mutterings he grows so annoyed that he punches himself in the other face.
* In the ''Series/DoctorWho'' episode [[Recap/DoctorWhoS31E4TheTimeOfAngels "The Time of Angels"]], the Doctor tells an anecdote about a planet of two-headed people.
-->'''The Doctor:''' Very relaxed, sort of cheerful. That's from having two heads. You're never short of a snog with an extra head. [...] Then they started having laws against self-marrying and what was that about? But that's the church for you.\\
[...]\\
'''Amy Pond:''' Church had a point, if you think about it. The divorces must have been ''messy''.
* ''Series/BuffyTheVampireSlayer''. Becomes the subject of an IncrediblyLamePun when Spike takes on a reptile demon.
-->'''Spike:''' All right, heads up! ''(demon lifts up three heads; Spike gets an OhCrap look)'' Heads it is then.
* Quera, Hera and Vera, the three heads of the Siren from ''TheAquabatsSuperShow'' episode "Ladyfingers!".
* The TV version of ''Series/TheHitchhikersGuideToTheGalaxy'' had to try and portray Zaphod Beeblebrox with the special-effects technology of the early 1980s and the budget of a BBC science-fiction series. The result was [[SpecialEffectsFailure not terribly successful]].
* In one episode of ''Series/MightyMorphinPowerRangers'', the MonsterOfTheWeek was a Two-Headed Parrot (one head was where you'd expect a head to be, the other was on its chest); at first the two heads were able to cooperate excellently, but the Rangers were able to get the jump on it by finding a tropical fruit it liked, and get the two heads arguing over it.
** That wasn't the first time; previously, there was Goatan the Lion Goat, another two-headed monster, who's two heads got along just fine.
[[/folder]]

[[folder:Music]]
* The eponymous conjoined twins of the fictional band Music/EvelynEvelyn usually get along fine, but their self-titled song "[[http://www.evelynevelyn.com/lyrics/evelyn.html Evelyn Evelyn]]" explores their disagreements:
-->''We grew up so very close.\\
A parasite needs a host.\\
I'm only trying to do what is best for us.\\
Well, I never asked for this, I never wanted this.\\
All that I want is some time to myself.\\
Looking in your eyes, I'm coming home.\\
Just get away from me, please just stop touching me.\\
You're always trying to be somebody else.\\
Now I realize I'm not alone.''
* 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"!''
[[/folder]]

[[folder:Myths & Religion]]
* ClassicalMythology: The Hekatonkheires (fifty heads), Typhon (a hundred dragon heads on his ''arms''), Cerberus (three heads), Orthrus (two heads), the Chimera (three heads of different animals and a snake for a tail), the Hydra (nine heads w/ the caveat that two new heads will replace any head that's lost except for one immortal head), Ladon (a hundred heads), Scylla (humanoid upper torso with six monstrous heads in place of a lower torso)... the Greeks really seemed to like this trope.
* Indian deities, Buddhas and Bodhisattvas are often depicted as having multiple heads. This is usually a visual metaphor for them being all-seeing.
* ChineseMythology describes several creatures with multiple heads, including Xiangliu, who has nine heads and the body of a snake.
* Similar to Xiangliu or the Hydra, JapaneseMythology has the Orochi.
* In Literature/TheBible, in the book of Revelation, Satan is depicted as a seven-headed scarlet dragon, and the Beast (traditionally identified as TheAntichrist), appears as a scarlet leopard with seven lion heads. Both cat and dragon have ten horns distributed among the heads.
[[/folder]]

[[folder:Podcasts]]
* ''Podcast/WelcomeToNightVale'' has Hiram McDaniels, who is literally a five-headed dragon. Cecil berates his audience about believing the stereotype of multi-headed beings bickering with themselves, right before [[StereotypeReactionGag Hiram proves it true]].
** A high school senior grows a second head, which ultimately leads to the football team getting disqualified (team numbers are counted by heads, not bodies, apparently). His mother has a head removed... the original one, because she likes the new one better.
[[/folder]]

[[folder:Poetry]]
* The poem "Us" by Creator/ShelSilverstein; something of an extreme example, as the accompanying drawing shows two faces stuck onto the ''same'' head.
[[/folder]]

[[folder:Puppet Shows]]
* The Two-Headed Monster from ''Series/SesameStreet''. "Mountains!" "Seashore!" or whatever the topic at hand is.
* Tom, Dick, and Harry from ''Series/TheMuppetShow''. They disagree about who's in charge of the... er... group?, what their intended act is, and such.
* Theres a two-headed monster in ''Series/GroundlingMarsh'' named Mud/Slinger. Their grandcestors (ancestors), were once two separate beings and lived alone in the marsh with no friends. After meeting, they became good friends, and wanted to be merged into one so that they'd never be alone again. They drank a potion that merged them into a two-headed being, and ever since then, all their descendants have been conjoined.
[[/folder]]

[[folder:Tabletop Games]]
* ''TabletopGame/DungeonsAndDragons'':
** Demon Prince Demogorgon, whose heads allegedly have ''competing spy networks'' and who constantly [[GambitPileup scheme]] against each other. They also have individual names; Aameul and Hethradiah.
** The five-headed Tiamat is, however, an aversion.
** Ettins are a race of two-headed giants. One head (usually the one on the right) is usually the dominant one, so they rarely argue. There was, however, a 3rd Edition adventure that featured a human man who was turned into an ettin, with his mind in the left head and a new evil personality in the right head that was slowly taking control.
** In the template-heavy days of 3.5, there was "Multiheaded Creature", although it did put a reasonable limit on how many heads were added.
** Subverted with Geryon in 4th Edition. He has three heads, with one being thoughtful and conniving, one being angry and cruel, and one being manic and gleeful. However, they actually share one mind, never argue with each other, and normally only one will talk at a time, with the dominant head being determined by his emotional state.
* [[AllTrollsAreDifferent Jotund trolls]] in ''TabletopGame/{{Pathfinder}}'' have ''nine'' heads which invariably all bicker with each other (usually about who gets to actually taste their prey).
* ''TabletopGame/{{Warhammer}}'':
** The first Chaos dragon, a good dragon that was corrupted by Chaos and grew a second head. His original personality is still in there somewhere and may attack the bad head during the battle.
** Tzeentch, God of [[BreadEggsMilkSquick change, hope and random mutation]] has a greater demon with two heads. Said demon's heads can see the past and future, respectively, but are a little oblivious to the present.
[[/folder]]

[[folder:Toys]]
* ''Franchise/{{Bionicle}}'':
** The Spikit, a double-headed beast of burden.
** Rahkshi Kaita Za, the [[CombiningMecha combiner model]] of Turahk, Lerahk and Kurahk.
[[/folder]]

[[folder:Video Games]]
* ''Franchise/{{Pokemon}}'':
** Dodrio's three heads symbolize joy, sorrow, and anger. Dodrio's first form, Doduo, has two heads, but they have identical brains (usually).
** Zweilous has two heads that don't actually get along. They compete for food, even though they share a stomach. This leads to overeating. And then it evolves into the three-headed Hydreigon, which subverts this trope by only having a brain in its center head.
** Vanilluxe and the Klink line from [[VideoGame/PokemonBlackAndWhite the same generation]] also have multiple heads.
** Exeggutor's 3 heads all think independently, though they never argue.
** Subverted by Binacle, although it's two barnacles attached to a rock, they can detach and move to another one. Played straight with its evolution Barbaracle, who's made of ''seven'' barnacle heads, four of which form its arms, another two its legs, and one for its "head". [[LeaderFormsTheHead They usually follow the head's orders]].
* ''VideoGame/WorldOfWarcraft'':
** Not true for most two-headed ogres. Though there are ''very'' few of those you can actually ''talk'' to, they're mostly just smart guys and might as well only have one head. Draz'zilb even refers to himself as "I".
** 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.
** In ''VideoGame/{{Warcraft}} II'' the heads would argue with each other if you kept clicking on them ("This way!" "No, this way!"). When they are upgraded to Ogre Magi, they start talking in unison, get their crap together, and learn magic powers.
--->'''First Head:''' We're not brainless anymore.\\
'''Second head:''' ''I've'' got the brain!\\
'''First Head:''' Nuh uh!
** There's actually one boss whose two heads argue with each other in a ''Burning Crusade'' dungeon. The fact that each head has a separate aggro table frequently makes this an example of ThatOneBoss for groups that bring a lot of [[SquishyWizard squishy]] characters.
--->"You always hungry -- that's why we so fat!"\\
"I want to kill this one. Get back here, you idiot!"\\
"I... hate... you..."
** There are also two bosses (Reliquary of Souls in ''Burning Crusade'', and Devourer of Souls in ''Wrath of the Lich King'') that are literally giant floating heads with three faces. They both have different voice actors, abilities, personas and even genders for each face.
* ''VideoGAme/{{Dota 2}}'' has two two-headed characters -- Ogre Magi (a spiritual successor to the ones in the Warcraft example above, considering the game's roots), and Jakiro, the Twin-Headed Dragon. Both characters mostly get along with themselves - Ogre Magi correct each other's mistakes and share control of the body, and have enough of a brain together to be somewhat intelligent, unlike most other ogres - although they do blame each other for dying, and, as an idle animation, they punch each other. Jakiro's heads congratulate each other on the remarks towards their rivals, as well as on some kills - when they're not trying to take the credit all to one of them, or when they're not blaming each other for failure. They also snap at each other as an idle animation occasionally.
* In ''VideoGame/KingdomOfLoathing'', the Boss Bat has two heads. So does a mini-boss, a two-headed zombie, which even references the Boss Bat fight.
* In ''VideoGame/{{Startopia}}'', the Turrakken race has two heads. When asked if they need anything, often each head will motion differently until they look at each other and agree. Which is probably why they make such good scientists. Each individual has two opinions, which allows for more ideas to be explored.
* ''VideoGame/QuestForGlory'': Whilst they all agree on the fact they're not going to let the [[TheHero Hero of Spielburg]], [[AwesomeMomentOfCrowning The Prince of Shapeir]], [[TheChosenOne The Saviour of Fricana]], [[IHaveManyNames and that oak that went to Moldavia]], pass, Cerebrus, the guardian of Hades, seem to bicker and bitch about the foodstuffs the other two heads prefer, to the degree that they nearly start fighting with each other.
* Ashton, from ''VideoGame/StarOceanTheSecondStory'' becomes fused in his introduction scene with a two-headed dragon. The two heads, Creepy and Weepy (or Gyrororo and Ururun in the Japanese version), constantly bicker with each other and with Ashton, though neither dragon head seems to take control of Ashton's arms and legs most of the time.
* The final boss of the flash game ''VideoGame/{{Arcuz}}'' is a two-headed giant who is/are ''elder brother and younger brother''.
* In the game ''VideoGame/EricTheUnready'', the title character has to get a two-headed oaf arguing with itself at one point to continue.
* There is a two-headed talking horse (aptly named Pushme Pullyu) in ''VideoGame/UltimaVI''. It resides in Blackthorn's Castle. This is a ShoutOut to ''Literature/DoctorDolittle''.
* In ''[[VideoGame/DragonsLair Dragon's Lair II: Time Warp]]'', on "The Garden of Eden" level, there's a two-headed serpent. One head tries to eat Dirk while the other tries to strike a deal.
* The Ettin in ''VideoGame/{{Stonekeep}}'' has two heads with very distinct personalities.
* ''VideoGame/DigitalDevilSaga'' has Heat's avatar Agni and Argilla's avatar Prithivi (which are located on the breasts). Heat also gives us this great line.
-->"Two heads means you will be devoured twice as fast."
* ''Franchise/SuperMarioBros'':
** Averted in both ''VideoGame/SuperMarioGalaxy'' and ''VideoGame/SuperMarioGalaxy2'' where all Thwomps, for some reason, have a face on the other side of their body, yet both are constantly scowling.
** Played straight with the Tox Boxes from those two games as with ''VideoGame/SuperMario64'', however.
* ''VideoGame/PlantsVsZombies'' has quite a few plants with multiple heads. While most of them show no signs of conflict, Cherry Bomb argues briefly with itself over whether to explode or detonate. [[TakeAThirdOption In the end, they agree to explodonate.]]
* ''VideoGame/KidIcarusUprising'' has Hewdraw, a three headed dragon who has an angry and boisterous head, a mellow head (who just wants to give up and go home), and a really posh, polite head that has a british accent. When you first meet them, the three heads wind up arguing in such a cacophony of noise that you can barely understand what they're saying. There's also Twinbellows, a two headed {{hellhound}}, but its heads don't form any kind of basis of their character.
* Near the end of ''VideoGame/DayOfTheTentacle'' the three protagonists appear to get turned into a three-headed hybrid by a [[TeleporterAccident time machine accident]]. [[spoiler:It later turns out they had simply gotten stuck inside one set of clothes.]]
* There's a two headed shopkeeper in ''VideoGame/SimonTheSorcerer'' whose heads bicker about where the merchandise should go ("The asparagus jelly belongs with the other jellies!" "I think it belongs with the vegetables!"). Apparently they don't share digestive systems, since one head complains about needing to go to the toilet and the other snaps that he'll just have to restrain himself.
* Billy the Brute from an Ettin in {{Wizard101}} acts similar to the Ettins from TabletopGame/DungeonsAndDragons. His right head is the dominant and more intelligent of the two and has to remind the left who's is friend and who's food. He's also a great stonemason.
* ''VideoGame/ToejamAndEarl: Panic On Funkatron'' has Flarney, a two-headed alien who often stumbles over his words, due to both his heads trying to talk at the same time, leading to him getting confused and forgetting what he was talking about. In the end he decides to have them take turns, each getting to say one sentence at a time.
* ''VideoGame/TakAndThePowerOfJuju'' has the redneckish Two-headed Juju. The left head is named Rufus and the right one is Jerry.
* ''VideoGame/JadeEmpire'' features the Minion of Suffering, who is humanoid, but has two cow's heads.
* Landia in ''VideoGame/KirbysReturnToDreamland'' is a four-headed dragon that's able to split into four, single-headed dragons. It's implied that it's actually the other way around, though, as if it's defeated in its fused state, it'll split apart, and it/they remain this way after the Master Crown is removed from them.
* Thrivaldi, the two-headed troll and TheDragon from ''HeroinesQuest''.
[[/folder]]

[[folder:Web Comics]]
* The chimera Trigak from ''Webcomic/TheOrderOfTheStick''. It had a dragon's head, a lion's head and a goat's head, each of which could talk; whether they had different personalities is unknown, [[spoiler:since Belkar killed it shortly after it appeared.]]
* ''Webcomic/YetAnotherFantasyGamerComic'':
** The Chimera: the dragon head is [[TheDitz an idiot]], the lion head is a {{Cloudcuckoolander}}, while the goat head is quite smart but doesn't control the body and thus is often very frustrated with the other two.
** Though even the Chimera isn't as bad as [[http://yafgc.net/?id=1006 this hydra.]]
** There is also a small story arc about a couple of ettins having love troubles, since both heads of the female ettin like the same head of the male ettin but not the other. The male ettin ends up asking the Chimera for advice.
* The [[http://partiallyclips.com/2002/09/11/paradox-dragon/ Paradox Dragon]] of ''Partially Clips'', parodying the KnightsAndKnaves trope.
* Donna and Diana from ''Webcomic/DungeonsAndDenizens''. Two heads on one hellhound body, hinted to be the result of momma dallying with Cerberus. Distinct to the point of considering each other sisters... and romantic rivals for the attentions of the same orc (who wisely does his best to avoid them).
* DJ Tonja in ''Webcomic/{{Muertitos}}'' 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.
-->'''Tonja:''' Could you at least stop eating while we're on the air? God, it's your fault we're so fat.\\
'''Coochie:''' Hey, YOU'RE fat, baby, I'M just a mouth on the back of your head.
* Isp, Osp, and Mosp in ''Webcomic/SluggyFreelance''.
* The travelling merchant's bandersnatch in ''Webcomic/{{Digger}}'' has two heads, and although they're clearly distinct entities (the bandersnatch-unit is referred to as "us"), they pretty much agree about everything, and alternate speaking with each sentence.
* Minerva the [[HellHound Cerberus]] in ''Webcomic/{{Spinnerette}}'' has three heads, each one with its own look and personality. The left head is the cute one, the right head is the brash, fiesty 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://krakowstudios.com/spinnerette/2012/01/09/01092012/ Issue #9]].
-->'''Middle:''' I knew this dress was too short...\\
'''Left:''' Compared to the [[ChainmailBikini metal bikini]]?
* Zeni and Nadi Tweeling of ''Webcomic/ContemplatingReiko'' are dicephalic conjoined twins. Much of the comic's rare bouts of lighter humor revolve around the issues of two girls with one body, or their strange episodes of obliviousness to their condition.
* The dragons/wyverns/whatever from ''Webcomic/OffWhite''.
* In ''Webcomic/CommanderKitty, [[BigBad Zenith's]] biggest and baddest monster [[http://www.commanderkitty.com/2011/10/09/battle-begin/ has not only a giant bear head, but a pair of dragon heads for arms]].

* [[http://conjoined.redwolf.ws Dr. Mercurious' webpage]] is proof that Rule 34 extends even here.
* In the "Dark Woods Circus" series of Music/{{Vocaloid}} PV's, Rin and Len Kagamine are confined to a mental institution and later [[BodyHorror have their heads chopped off and sewn onto one body]].
* [[VideoGame/TeamFortress2 Meet the]] [[http://www.youtube.com/watch?v=gTf2-8xCaYk Heavy Heavy Heavy]].
* In ''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.

[[folder:Western Animation]]
* Ted and Tina Twingersnap from ''WesternAnimation/VivaPinata''.
* PorkyPig encounters a three-headed creature in ''WesternAnimation/PorkyInWackyland'', whose heads bicker and argue. Also each head had their distinct haircut, [[Film/TheThreeStooges with one having a bowl cut, one with a messy mane, and the third being bald.]]
* Two-Badd of ''WesternAnimation/HeManAndTheMastersOfTheUniverse1983'' fame. In fact, in [[WesternAnimation/HeManAndTheMastersOfTheUniverse2002 the remake]], they devoted an episode to explaining how they came to exist and another episode to their scheme to become separated from each other.
* ''WesternAnimation/FilmationsGhostbusters'' has the similar Fib-Face. His two faces were attached to one head 90 degrees from each other, and one can never be sure which head's telling the truth and which one's lying. Again, the only way to defeat him is to get the two heads arguing.
* One of the ''ComicStrip/{{Popeye}}'' two-reelers, ''WesternAnimation/PopeyeTheSailorMeetsSindbadTheSailor'', includes a two-headed giant named Boola. Although they seem to not to suffer from bad coordination, they do appear a little unintelligent and tend to argue.
* Not only does the title character of ''WesternAnimation/CatDog'' have two heads, one's a dog and the other is a cat... and they're on opposite ends of the body. Although, they're just ConjoinedTwins, not two heads on one creature.
* The Son of the Chicken from Outer Space from ''WesternAnimation/CourageTheCowardlyDog'' has three heads. One head is nerdy and has glasses, one head is an angry jerk, and the center head is an idiot with his tongue hanging out. The outer heads have complete control over their respective arm and they often punch each other while arguing.
* Triple Threat from ''[[WesternAnimation/TeenageMutantNinjaTurtles2003 Teenage Mutant Ninja Turtles: Fast Forward]]'' is a wrestler/thief with three different heads. One of them is violent, the other calculating, and the third is a {{Cloudcuckoolander}}.
%%* ''WesternAnimation/SabrinaAndTheGroovieGoolies'' also has a character with two heads.
* ''Series/TheSuperMarioBrosSuperShow'' features the tri-headed Tryclide, a serpent with 3 heads.
* Zak and Wheezie from ''WesternAnimation/DragonTales'' take this trope a little further than most: not only do they have different characters, they have different ''genders''. It's a show for very little kids, so don't expect any of the inevitable (and potentially nightmarish) FridgeLogic to be addressed.
* ''WesternAnimation/{{Futurama}}'':
** "Put Your Head on My Shoulder" has Fry's head sewn onto Amy's shoulder.
** We also see a goat with heads at both ends. The vet mentions that [[MindScrew one needs to take pills, the other needs a suppository.]]
%%* Charles and Mambo on ''WesternAnimation/{{Duckman}}''.
* ''Franchise/{{Transformers}}'':
** The version of Blitzwing from ''WesternAnimation/TransformersAnimated'' has three faces for each of his three personalities, which occasionally argue with each other. Like some other examples on this page, he's got one head with multiple faces, though only one face is ever visible at a time.
** And Alpha Q from ''Anime/TransformersEnergon'' has ''four'' faces. It's implied that he wasn't always so schizoid, but developed the multiple personalities out of loneliness when he was trapped inside Unicron.
** Based on the Quintessons from ''G1'', who all had five faces. Alpha Q's full name, Alpha Quintesson, is only heard once. However, he only has four faces. His mask is always closed when his fifth personality, considered his 'true face' despite no physical face representing it (we see the inner sphere turn 360 more than once; there ''isn't'' a fifth face), speaks. Alpha Q's real self speaks in the VoiceOfTheLegion - Alpha Q is eventually revealed as the combined consciousness of everyone lost in his planet's destruction.
*** There's a difference, though: The G1 Quintessons only had one voice and personality apiece, the head-switching being purely cosmetic. ''Energon's'' Alpha Q is more like Blitzwing, each of his faces having a different temperament and sometimes arguing.
** Another humorous example would be an extra from ''Franchise/TransformersGeneration1'', season 3. One of the patients on the therapy planet Torkulon has three heads... who keeps saying "I have no head... I have no head... I have no head..." Definitely [[IncrediblyLamePun a head-case]].
** Doublecross, Hun-Gurrr, and Sinnertwin, who transform into twin-headed dragons, each suffer from split personalities, a condition which is (naturally) exacerbated in their beast modes. Sinnertwin even has two voice actors. Though technically, they're all three-headed. Sadly, we don't get a third VA for the robot mode head. Just as well, because Sinnertriplet doesn't make nearly as cool a name.
** Magmatron from ''Anime/BeastWarsNeo'' -- no relation to any version of Megatron -- has three heads. One is in the usual spot, and he's got one on each shoulder. He has the ability to separate into three autonomous units, but he is definitely one person.
** The upcoming ''WesternAnimation/TransformersPrime'' toyline "Beast Hunters" features a Sinnertwin lookalike known as Twinstrike.
*** The same toyline also brings back Hun-Grrr as a twin-headed dragon.
* This is averted in the AnimatedAdaptation of ''Literature/TheNeverendingStory'', where a three-headed character never has more than one head "awake" at a time. In the book, it was four.
* Creator/HannaBarbera's 1960s version of ''Literature/AlicesAdventuresInWonderland'' has a caterpillar with a head at each end, who just happened to look (and sound) like [[WesternAnimation/TheFlintstones Fred Flintstone and Barney Rubble]].
* Frank and Len from ''WesternAnimation/RubyGloom'' are a two-headed rock musician. Frank is smarter than Len, though not much.
* On ''WesternAnimation/TheGrimAdventuresOfBillyAndMandy'', Grim's three-headed dog doesn't talk, but his heads (two husky-types and one poodle) don't always act the same. Two of his heads were immediately attracted to Mindy's chihuahua Little Delicious, and exchanged glances of dismay when they realized the middle head was growling at her.
* In an episode of ''WesternAnimation/JackieChanAdventures'', Jackie got influenced by a powerful magical pair of tigers and ended up with two heads, one very good and the other evil. [[spoiler:They're actually his Yin and Yang, who showed up in the first season when he was split in two by one of the plot artifacts. The evil one is a pushy jerk, and the good one is a LovableCoward who only fights reluctantly.]]
* ''WesternAnimation/PlanetSheen'' has Princess Oom. One face is a bubbly cheerleader type and the other is an intense seductress. Both are in love with Sheen.
* Agatha and Emily, the two-headed vulture from the WesternAnimation/BugsBunny cartoon ''Transylvania 6-500''. She gets along quite well with herself. Also [[spoiler:Count Blood Count, after Bugs transforms him into a male two-headed vulture. Agatha and Emily are delighted and chase him off into the night.]]
* Red Mantle and Dragoon from ''WesternAnimation/TheVentureBrothers''. A recently-joined pair (forced when Dragoon was dying after a tussle with [[TouchOfDeath Phantom Limb]]) who argue constantly over which of them is actually in charge. Thus far, Dragoon has taken over the left side.
* One ''WesternAnimation/{{Underdog}}'' short has him facing a two-headed dragon which would stop to shake hands with itself chanting "Teamwork, teamwork, that's what counts!"
* On ''WesternAnimation/JimmyTwoShoes'', a two-headed man is one of the many citizens of Miseryville. [[TheLegionsOfHell He does not look out of place]].
* The ''WesternAnimation/FamilyGuy'' episode "Road to the Multiverse" features a universe where everyone has two heads: one happy, one sad.
-->'''Happy!Tom:''' The President's dog just had puppies!\\
'''Sad!Tom:''' But there was a plane crash.
* In the ''WesternAnimation/JohnnyTest'' episode "Li'l Johnny", Johnny runs into Susan and Mary's lab to find them as two heads on one body. Their expanation? [[NoodleIncident Don't ask!]]
-->'''Mary:''' [[MindScrew So is your head on my body or is my head on your body?]]
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'':
** The episode [[Recap/MyLittlePonyFriendshipIsMagicS1E15FeelingPinkieKeen "Feeling Pinkie Keen"]] sees the girls getting attacked by a four-headed hydra. Amusingly enough, one of the heads appears to be a little slow on the uptake; the other three heads roar in unison, for example, but the fourth one doesn't join in until it realizes what the other heads are doing.
** The talking chimera in [[Recap/MyLittlePonyFriendshipIsMagicS4E17SomeponyToWatchOverMe "Somepony to Watch Over Me"]] has three heads, each with their own distinct personalities: 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.
--->'''Tiger Head:''' You've got no idea what it's like to have a sister [[VisualPun constantly looking over your shoulder!]]
* A character named Cindy was this in ''WesternAnimation/LloydInSpace''. One head was nice and attractive; the other, mean and ugly. Lloyd only wanted to date the nice one; the girls weren't having it.
* The 1960's Depatie/Freleng cartoon show ''WesternAnimation/TheSuper6'' had a 3-headed character(s) named the Matzoriley brothers. Unfortunate ethnic stereotypes in triplicate, alleviated mildly by the fact they kept trying to beat up one another.
* Crygen and Pyre, the two bickering halves of Magnokor on ''WesternAnimation/{{Inhumanoids}}'', sometimes merged into a two-headed and still-bickering form.
* In ''WesternAnimation/GarfieldAndFriends''/''U.S.Acres'', in the episode "Hogules II", in Orson's dream, Roy and Wade are a two-headed giant. Sharing the same body? Check. [[SensitiveGuyAndManlyMan Different personalities?]] Check. [[VitriolicBestBuds Arguing with each other?]] And check.
* In one ''WesternAnimation/TheJetsons'' 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.
* ''WesternAnimation/TheBaskervilles'': The Baskervilles had a robotic three headed hound named Spot. Each head could talk and had its own personality: Cool Spot a sunglasses wearing dude who is April's best friend; Bad Spot a rabid monster who loves nothing more than total destruction; and Dumb Spot a complete idiot, likely the dumbest creature in the whole park.
* The Bulldrafish from ''WesternAnimation/TakAndThePowerOfJuju''. Each head has it's own personality; The bull head is aggressive, the dragon head is sweet, and the fish head is obnoxious.
* Headbanger of the short-lived ''Toxic Crusaders'' cartoon. He's a mutated freak with two heads who each control their side of the body. One head's a hideous MadScientist; the other's an oafish SurferDude. 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.
* In ''WesternAnimation/MenInBlack'', [[BigBad Alpha's]] first OneWingedAngel form after merging with several aliens using the Cosmic Integrator had multiple heads. A later episode reveals that the heads still have minds of their own, and they aren't happy about being trapped in Alpha's body and forced to do his bidding. A Symbiote that was absorbed by Alpha asks the others if they ever considered making a break for it, and they ask him how they can escape without bodies of their own. [[spoiler:The fact that they still have their own bodies and cells is a method to how Alpha is finally defeated in that episode: When Alpha absorbs a second Symbiote (the mother of the first who's trying to get him back), the [[GoodThingYouCanHeal regenerating factor]] both Symbiotes possess is infused into all of Alpha's cells ''and those of his sentient grafted body parts'', allowing them to regenerate their own bodies and break free of Alpha's own.]]
* ''WesternAnimation/TenkoAndTheGuardiansOfTheMagic'': Villains Janna and Jason can perform a FusionDance into a two-headed dragon, with each of them in control of one head.

[[folder:Real Life]]
* TruthInTelevision with dicephalic conjoined twins [[https://www.youtube.com/watch?v=ZBtYomZWR68 Abigail and Brittany Hensel]], who share one body and so present the appearance of one two-headed person. Only three prior sets of dicephalic twins living to adulthood have been recorded in all human history. However, unlike the Hollywood version each only has control and feeling of her own half of their combined body. Unlike the various "bickering heads" (including the reptiles below), though, they seem to be very well-coordinated and aren't known to argue excessively. When getting their drivers license, they had to take the test twice. They may be conjoined but are two individual, if not exactly separate, people. It does make one wonder what would have happened if only one had passed the test.
* [[OrganAutonomy Each of an octopus' eight arms has its own brain, and even a distinct personality.]] One arm may be aggressive, one may be curious, one may be shy, etc. Thankfully for their owner, they usually get along.
* Reptiles, due to their biology, are more likely to develop two heads on one body than most other animals (though it's still extremely unlikely). They don't move very well, will fight each other for food, and the carnivores (such as snakes) will actually try to eat each other.
