* ''Animation/{{Krisztoforo}}'''s format has Bőfejű, the plenty-headed dragon (13 to be specific, or 14-minus-1 according to the creators) telling stories about the eponymous knight to his child, the 3-headed Önfejű. Bőfejű's name means "Plenty-Head".

[[folder:Eastern Animation]]
* Most of the dragons in ''Animation/HungarianFolkTales'' follow the tradition of having either three, seven or twelve heads. Because of the folk art-inspired animation style, at times they appear as green humans with one head adorned with multiple faces.
* Each episode of the 90s Hungarian [[StopMotion claymation]] series ''Animation/{{Krisztoforo}}'' features the 14-minus-one-headed dragon named Bőfejű ("Plenty-Head") telling a bedtime story to his three-headed baby. Every head seemingly has its own name and personality, which is not obvious at first [[ActingForTwo because there's only five voice actors]] and their names are rarely said.

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's 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/TheSimpsons'' WesternAnimation/TreehouseOfHorror episode "Homer's Nightmare", at the very end when Mr. Burns' body is crushed, so he has his head surgically grafted to Homer's ample frame.

[[caption-width-right:250: Don't expect them to agree on anything!]]

* ''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.
** In [[http://yafgc.net/comic/1006-hydra-condriac/ one strip]], the Chimera encounters a hydra whose heads are constantly arguing, bickering and squabbling -- for example, they first argue about which path to take and then fight to assign blame when that path proved a poor one.
** One story arc follows a couple of ettins with 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.
* ''Webcomic/PartiallyClips'': The [[https://web.archive.org/web/20100220193527/http://partiallyclips.com/2002/09/11/paradox-dragon/ Paradox Dragon]] (archived link) parodies the KnightsAndKnaves puzzle, with the dragons' three heads being unable to even agree on the rules, squabbling until it died of a migraine.
* ''Webcomic/DungeonsAndDenizens'': Donna and Diana are two heads on one hellhound body, hinted to be the result of momma dallying with Cerberus. They're 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).

* ''Webcomic/{{Digger}}'': The travelling merchant's bandersnatch 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.

* ''Webcomic/ContemplatingReiko'': Zeni and Nadi Tweeling 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.
%%* ''Webcomic/OffWhite'': The dragons/wyverns/whatever.
* ''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.]]
%%* ''Webcomic/{{SinFest}}'': Cerberus.
* ''Webcomic/{{Housepets}}'': Cerberus' heads' speech bubbles are colored in different shades of blue, but the only time they're seen talking to one another it looks more like [[http://www.housepetscomic.com/comic/2016/05/02/talking-heads/ thinking out loud]].
* ''Webcomic/SlightlyDamned'': Cerberus is currently two-headed, and three-headed in flashbacks. The mental capacity of the heads varies. While its heads do get along, the severed third does enjoy the opportunity to spend some time alone.

* ''WesternAnimation/TheGrimAdventuresOfBillyAndMandy'': Grim's dog Cerberus doesn't talk, but his heads (two husky-types and one poodle) don't always act the same.

In the episode "Dream a Little Dream" during a nightmare sequence in Billy's mind, a bunny transforms and grows a second head

-->'''Plucky second head:'''Don't look now pal but you just became a duo.

* Creator/GamesWorkshop games:
** ''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.
** ''TabletopGame/{{Necromunda}}'': Having two heads is one of the options for mutant Scavvies. The mutation gives the model a 180 degree field of vision and allows them to [[GunsAkimbo fire two pistols at the same time]] as each head is able to aim and fire one of the guns.
** Examples present in ''TabletopGame/Warhammer40000'', ''TabletopGame/{{Warhammer}}'' and ''TabletopGame/WarhammerAgeOfSigmar'':
*** Kairos Fateweaver, a Greater Daemon of Tzeentch, the [[BreadEggsMilkSquick God of change, magic, hope and random mutation]], has two heads, one of which can only see the past while the other can only see the future.
*** Karanak, the Hound of Vengeance, is a three-headed Flesh Hound of the Blood God Khorne to fit with his [[Myth/GreekMythology Cerberus]] theme. The first of Karanak's heads can track his quarry across space, the second follows them across time while the third can sense his prey's thoughts.

%%* ''TabletopGame/MagicTheGathering'' has Hydra cards, which typically have a varying number of +1/+1 counters (representing their heads) depending on how much mana is used to cast them. Below is an example in the [[https://gatherer.wizards.com/Pages/Card/Details.aspx?popularpage=1&multiverseid=202586 Rock Hydra]]:
%%-->''"Put X +1/+1 counters (heads) on Hydra. Each point of damage Hydra suffers destroys one head unless R is spent. During upkeep, new heads may be grown for RRR apiece."''

* In ''Toys/FlushForce'', there is the Gruesome Twosome team, made up of two-headed animals.

* ''VideoGame/FaceRaiders'': There is a two-faced enemy that represents angry and sad on its sides.

* ''VideoGame/{{Bayonetta}}'':
** Many of the angels in the series are a notable aversion of this trope. All of them are {{Eldritch Abomination}}s, and many of them have multiple heads or faces, but each of them is depicted as a singular entity. Most notably, the Auditio Fortitudo is a dragon with three heads/faces, much like the Hydreigon example, but only one of its heads (the humanlike face [[BellyMouth on its chest]]) is shown to have a personality/mind and presumably controls the whole creature.
** The demon Greed has three heads and, unlike most of the angels, is depicted as a savage, feral creature. As such, it's unknown whether it plays this trope straight or is another notable aversion.
* ''VideoGame/DahnaMegamiTanjo'' has a two-headed, [[MultiArmedAndDangerous four-armed]] demon knight serving as a boss, and as the battle progresses it [[AnArmAndALeg lose two limbs]] and [[OffWithHisHead a head]] before it's knocked off a tower. The same boss returns a few levels later after its defeat for a rematch, with only two arms and a head.
* ''VideoGame/Dota2'' 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.
%%* ''VideoGame/KingdomOfLoathing'': The Boss Bat has two heads. So does a mini-boss, a two-headed zombie, which references the Boss Bat fight.
* ''VideoGame/KingdomRushOrigins'': Ettins have two heads that disagree with each other every now and then, causing it to hit itself with its own club and stunning it for a brief while.
* ''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.
* ''VideoGame/{{Arcuz}}'': The final boss is a two-headed giant who is/are are a sibling pair -- and, somehow, one is the elder and the other is younger.
* ''VideoGame/EricTheUnready'': Eric has to get a two-headed oaf arguing with itself at one point to continue.
* ''VideoGame/UltimaVI'': There is a two-headed talking horse, named Pushme Pullyu as a ShoutOut to ''Literature/DoctorDolittle''. It resides in Blackthorn's Castle.
* ''VideoGame/DragonsLair'': In ''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.
* ''VideoGame/{{Stonekeep}}'': The Ettin 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'': Played straight with the Tox Boxes.
* ''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.
* ''VideoGame/DayOfTheTentacle'': Near the end 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.]]
* ''VideoGame/NinjaShadowOfDarkness'': The second boss is a two-headed {{Hellhound}}. When it first appears in a cutscene, both heads are actually arguing and snapping at each other, until your protagonist steps into view. Cue boss battle.
* ''VideoGame/SimonTheSorcerer'': There's a two-headed shopkeeper 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. It is revealed if you listen to them long enough, that they were originally one person (The right head) but he touched a glowing stone, causing a second head to grow from his shoulder. Whether this is magic or a mutation is never explained.

* ''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.
* ''VideoGame/KirbysReturnToDreamLand'': Landia is a four-headed dragon that's able to split into four, single-headed dragons. It's implied that its split form may be is true one, 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.
%%* ''VideoGame/HeroinesQuest'': Thrivaldi, the two-headed troll and TheDragon.
* ''VideoGame/StarCommandRevolution'' has a BrainInAJar example with the Triumverite race; beings with three disembodied brains floating in a canister where a head would be on a human. The responses of their in-game units include "Three heads are better than one!" They seem remarkably in sync, though.
* ''VideoGame/TheUltimateHauntedHouse'': Herbert and Chauncey are a strange purple two-headed monster who love nothing more than to eat disgusting objects like severed body parts. Appetite aside, they're fairly cheerful and friendly for monsters, though whether they are a NonMaliciousMonster or LaughablyEvil depends on the [[GeniusLoci mood of the house]].
* ''VideoGame/MordheimCityOfTheDamned'' has a partial example played for BodyHorror. The Extra Face mutation gives a Chaos fighter [[ExactlyWhatItSaysOnTheTin a second face]] which overlaps with the original, resulting in a face with two noses, three eyes and two sets of lips over an enormous mouth. The effect is akin to a visual glitch and very freaky.
* ''VideoGame/KillerInstinct'' has the unusual case of Eyedol, who had two separate heads in the original ''KI'' while the reboot gave him two ''[[BodyHorror halves]]'' of a head, thanks to [[TheRival Gargos]][[note]]This is discounting the fact that Reboot!Eyedol has alternate costumes that give him two different heads, including a Classic costume[[/note]]. Despite this, the reboot version fits the spirit of the trope better; he uses a StanceSystem based on which head is awake (one is a rushdown character, the other is a zoner), the player can change styles by [[SelfHarm punching the sleeping head until it wakes up]], and his [[SuperMode Instinct Mode]] wakes both heads at the same time and combines their moves (like the rushdown form's {{Shoryuken}} being followed by the zoning form's meteor rain).
* ''VideoGame/{{Paladins}}'': Moji's familiar[=/=]steed, Po-Li, has two heads. The left one has a derpy face and shoots energy balls. The right one has a serious face and sprays magical fire. While not very powerful on their own, their attacks are much stronger when used together. They also both love Moji very much and often compete for her affection.
* ''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]].
* ''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.
* ''VideoGame/{{Miscreated}}'' has two-headed dogs as an enemy type.
* ''VideoGame/KrushKillNDestroy'': The two faces of the female mutant in ''[=KKnD 2=]'' do not get along.
* ''Franchise/MegaMan''
** ''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/MegaManZero1'': As a Mechaniloid based on the Orochi, the guard Orotic has eight head, a pair each for FireIceLightning and NonElemental.
* ''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.

* ''VideoGame/MonsterHunterGenerations'': The Nakarkos is one of these [[{{Dracolich}} made from bones]]... [[spoiler:or so it seems. It's actually a massive cephalopod-like monster that attaches the bones of the prey it eats to its tentacles to maintain the ''appearance'' of a two-headed corpse serpent, tricking its foe into thinking it's fighting more enemies than it really is.]]

* ''VideoGame/IslandSaver'': The Mythic Wolf, Funny Flamingo and Mythic Turtle of Fantasy Island each have two heads.

%%* Averted by the three-headed Tusseladd 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.
%%* The two-headed Makhai from ''Film/WrathOfTheTitans''.

* ''Literature/HarryPotter'': [[http://harrypotter.wikia.com/wiki/Runespoor Runespoors]], a species of magic snake from the background book ''Literature/FantasticBeastsAndWhereToFindThem'', have the three heads each with 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.
* ''Literature/{{Abarat}}'': The Brothers John, one of whom is a {{Jerkass}} who always bickers with the others.
* ''Literature/FirstPersonPlural'': The brothers are dicephalus conjoined twins (two heads, one body). One brother is gay and the other is straight.
%%* ''Literature/DoctorDolittle'' features the Pushme Pullyu, a two-headed antelope.
* In one of Creator/GKChesterton's stories, after several knights have failed to kill a one-headed giant, Red Legs kills a two-headed one because it's too busy quarreling with itself to notice his approach.
* ''Literature/{{Triss}}'': Zassaliss, Harssacss, and Sesstra 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...
* ''Literature/ACanticleForLeibowitz'': Shows up twice, 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, as her second, atrophied head begins to display more and more independent will, is played as the return of a sinless being to earth, highlighting the book's theme of history being cyclical.

%%* ''Literature/StarlightAndShadows'': Zz'Pzora is a mutant Deep Dragon with two heads.

* ''Literature/OlogySeries'': Hydras, in ''Dragonology'', typically have three heads, but can have more. ''Monsterology'' includes chimeras, with the usual snake, goat and lion heads, and a prehistoric phoenix parasite preserved in amber, which appears to be an insect with two heads.

* ''Series/GroundlingMarsh'': Had Mud/Slinger, a two-headed Groundling, each being their own distinct person.

%%* ''Series/SesameStreet'' is demonstrating the number two by showing animals in nature, reciting, "two arms", "two horns", etc. finishing with a two-headed snake.

* Many 1960s PsychedelicRock albums like to portray multiple headed gods on their album cover, inspired by Hinduistic and Buddhistic art. Examples are Music/JimiHendrix' ''Music/AxisBoldAsLove'' and ''Music/AnthemOfTheSun'' by Music/TheGratefulDead.

[[folder:Puppet Shows]]
%%* ''Series/SesameStreet'': The Two-Headed Monster. "Mountains!" "Seashore!" or whatever the topic at hand is.

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 of their descendants have been conjoined.

* Double-Header of the [[ComicBook/LegionOfSuperHeroes Legion of Substitute Heroes]] in Franchise/TheDCU -- 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.

* Divangelic in ''ComicBook/{{Empowered}}'' certainly looks like the two halves would have contrasting personalities, since one of them dresses as a [[HotAsHell sexy demoness]] and the other as an angel; she was always just a background character, though, so we never get to see them talk.
* ''ComicBook/TheIncredibleHulk'': Bi-Beast. Justified, since he's an android.

They always either SpeakInUnison or finish each other's sentences.
* ''Franchise/{{Superman}}'':

** In ''ComicBook/TheImmortalSuperman'', the titular hero runs into an old super-hero who once fought a weird four-headed monster called Kono-Beast.

[[folder:Films -- Animation]]
* ''WesternAnimation/QuestForCamelot'': Devon and Cornwall, the two-headed dragon. They/he can't fly unless both heads can agree, which isn't often. They even have a full DisneyAcidSequence [[https://www.youtube.com/watch?v=v-nNhGikahU song]] about how much better their lives would be if they were apart.
* ''WesternAnimation/HowToTrainYourDragon'': Barf and Belch are one of a two-headed species of dragon called the Hideous Zippleback. The two heads work well in tandem, with Barf breathing out a flammable gas which Belch then ignites with a spark. However, having two separate riders, who happen to be bickering siblings, things are bound to get a little... difficult.
* ''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.
** Cerberus's three heads are shown fighting each other over a steak that Hades throws to them.

* ''Anime/TheLittlePrinceAndTheEightHeadedDragon'': {{Orochi}}'s heads frequently fight over vats of wine, over who gets to eat Prince Susano, and two of the last three heads outright bite each other off.
* ''WesternAnimation/TheLEGOMovie'': Bad Cop/Good Cop 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. When Mike tries to [[LoopholeAbuse submit them as two people]] for the Scare-Offs to reach a minimum ''head''-count, he's immediately shut down due to monsters with multiple heads being commonplace, so they only count ''bodies'' instead of heads.
* ''[[https://www.youtube.com/watch?v=HvSaBVSAkz4 Dobrynya Nikitich and Zmey Gorynych]]'': Zmey Gorynych. Despite being referred to in the singular and being introduced with all three heads speaking in unison, the three heads frequently converse with each other and speak independently, with Zmey alternating between referring to himself in the singular and plural (though this might actually be a translation gaffe). The left head has a high-pitched voice, the middle head has a low-pitched voice, and the right head speaks with a pitch somewhere between the other two.
%%* ''WesternAnimation/RalphBreaksTheInternet'': Double Dan.

%%* ''The Thing with Two Heads'' plays this seriously. [[{{Narm}} Or at least they try to.]]
%%** Ditto ''The Incredible 2-Headed Transplant''.

* In ''Fanfic/AbraxasHrodvitnon'', [[Film/MonsterVerse Vivienne Graham and San]] have this after their transformation into a TwoBeingsOneBody {{Kaiju}}, with their merged form having two heads which house either of their minds, similar to Ghidorah's three heads before them. In their [[CameBackWrong first]] [[PowerIncontinence form]], San's head is little more than half a vestigial head located on their back, but he gains a fully functional head and neck after their [[EmergencyTransformation second transformation]].

* [[VideoGame/TeamFortress2 Meet the]] [[https://www.youtube.com/watch?v=gTf2-8xCaYk Heavy Heavy Heavy.]]

* In the ''Fanfic/PonyPOVSeries'', the [[PhysicalGod Dragon Goddess]] Queen Tiamat is a gigantic {{Kaiju}} sized dragon with five heads. Each head seems to have a mind of its own, but they never fight. When she meets [[spoiler:Queen Majesty]], each head is also shown having differing emotions and reactions, with one even ''sleeping'' while the others are fully awake.

* The ''Anime/MyHime'' fanfic ''Fanfic/DuranAndKiyohimesOmakeTheater'' presents Shizuru's CHILD, Kiyohime, this way. Kiyohime is a hydra with six heads. They all have different tastes in music (and thus their own [=iPods=] and headphones. They all insist on having their own food bowl (even though, as Natsuki points out in protest, they all share one stomach), and head # 4 seems to be a daredevil, while at least three of the other heads are presented as more sensible.

* In ''Film/TheHitchhikersGuideToTheGalaxy2005'' 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!

* ''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.
* 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.
* Averted by most incarnations of King Ghidorah in the ''Franchise/{{Godzilla}}'' franchise -- his three heads don't seem to have any distinct personalities from one another.
** PlayedStraight by his Film/MonsterVerse incarnation in ''Film/GodzillaKingOfTheMonsters2019'', where his three heads display distinct personalities and are explicitly stated by the director to have separate minds (and are even portrayed by three different motion capture actors). The middle head is the dominant, most intelligent and most prominently sadistic head; the right head is a HotBlooded BloodKnight, and the left head is a PsychopathicManchild with a [[MinionWithAnFInEvil short attention span]] that often annoys the middle head. His RedBaron title even reflects on this, as he's known as "the One Who is Many", and the director even gave each head its own name (Ichi, Ni and San/Kevin).

* ''WesternAnimation/AtomicBetty": In "Spliced", Penelope and her posse get spliced together, becoming a three-headed mutant.

* ''WesternAnimation/TheGrimAdventuresOfBillyAndMandy'': Grim's dog Cerberus doesn't talk, but his heads (two husky-types and one poodle) don't always act the same. Two of his heads are immediately attracted to Mindy's chihuahua Little Delicious, and exchange glances of dismay when they realize that the middle head is growling at her. In the episode "Dream a little dream" during a nightmare sequence in billys mind, a Bunny transforms and grows a second head

* ''WesternAnmation/KidCosmic': Boss Fiosa is a two-headed alien crimelord who wields the fire and ice stones. It's ambiguous whether her two heads have separate consciousnesses or not.

* ''Literature/TheDivineComedy'': In addition to Cerberus (who has three heads like in the original myths), Satan himself has three heads, meant to be the opposite of the Holy Trinity.

* All of the vertebrate-analogues on ''WebOriginal/{{Snaiad}}'' have two heads, the first head being a beaked cranium that contains the reproductive organs and most closely resembles a head, and the second head being a BellyMouth of sorts that usually displays a long proboscis-like tongue. However, the trope is ultimately subverted: neither of the heads actually contains the brain, it being located inside a special bony keel inside the ribcage.

* ''WesternAnimation/TheGrimAdventuresOfBillyAndMandy'': Grim's dog Cerberus doesn't talk, but his heads (two husky-types and one poodle) don't always act the same. Two of his heads are immediately attracted to Mindy's chihuahua Little Delicious, and exchange glances of dismay when they realize that the middle head is growling at her.

* ''WesternAnimation/TheVentureBrothers'': Red Mantle and Dragoon are 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. By the show's time, Dragoon has taken over the left side.
