Two heads? How can you feed 'em?
Two heads! Day after day...
...It's drivin' me crazy in every way!
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. In some cases, these heads may cooperate closely, or at least as well as any close pair of allies can be expected to. In more comedic series, the heads will often argue with each other over which course of action to take. In more dramatic situations, the two heads will despise one another and resent their physical joining.
The specifics of how the body is controlled vary from case to case. Sometimes, the two personalities share seamless control. Other times, it may be possible for one head to take full control of the body, which may lead to bickering for dominance as each self tries to seize control from the other. In yet other cases, each head can only control the limbs on its own side.
When this applies to a creature with a Breath Weapon, it's common for each head to have its own specific weapon.
- One 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 attacks the other.
- In Digimon Adventure 02, the Digimon Kaiser gives Daisuke a Sadistic Choice: he can save only one of his four friends (and their Digimon) and not all of them because Deltamon has three heads and is hungry.
- Ebonwumon of Digimon Tamers has two heads, with each being voiced with a different accent in the dub. Both heads are generally in agreement with each other, though.
- Happens many times in Franken Fran. 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.
- King Ghidorah's three heads in Godzillandsometimes bicker, such as in the episode where they fight over a cake at Godzilla's birthday party.
- Discussed in Heaven's Design Team in regards to why there aren't any animals alive today that normally have multiple heads.
- 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 Snake People with their tails hopelessly imbricated rather than conjoined twins.
- Cerve, the cerberus from Monster Girl Doctor, has two dog heads growing out of her shoulders.
- One Piece:
- The giant Judge Baskerville of Enies Lobby 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 Ax-Crazy. Subverted when it's revealed to be three different people with very odd physiques sharing a shirt.
- Consuming an Artifical Zoan-type Devil-fruit called SMILE, can result in this for real, such as Holdem, who has a lion's head and front-legs growing out of his stomach, called Kamijiro. They often fight, which usually ends with Kamijiro performing a Groin Attack on Holdem...which of course also hurts it, since they share the same body.
- Kanan/Shuko/Junrei (collectively known as Honlon) from Pet Shop of Horrors. She's (they're?) a three-headed dragon with a different personality for each head. 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. However, this manifests as Literal Split Personality in their one-headed (shared) human form.
- Rouge in Ranma ½, having fallen in the Spring of Drowned Asura, has three faces (all on different sides of 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.
- Tengen Toppa Gurren Lagann: The series' flagship mecha, Gurren Lagann, is formed by combining two face-like mecha (Gurren and Lagann). The resulting combination has two faces (one on its head and one on its torso), which are piloted separately and "speak" and emote with each of their corresponding pilots. However, there are a few instances where Simon subverts this by piloting Gurren Lagann by himself.
- The Three Sisters in the first Vampire Hunter D 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.
- All-Star Comics: Gallifron is a giant two headed child eating ogre who acts as Loreli's most dangerous individual enforcer.
- Double-Header of the Legion of Substitute Heroes in The DCU — 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 Ultimate X-Men, 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.
- Green Lantern:
- One member 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. The innocent head has no control over their body and can only watch his brothers' crimes helplessly.
- A four-headed, multi-limbed creature formed from the remains of four Football Hooligans is sent to kill John Constantine in one issue of 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 Meat Cake comics. Although it's not sure if they're siamese twins... They argue constantly, though.
- 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 Seven Deadly Sins. They don't get on with each other very well.
- Divangelic in Empowered certainly looks like the two halves would have contrasting personalities, since one of them dresses as a sexy demoness and the other as an angel; she was always just a background character, though, so we never get to see them talk.
- Incredible Hulk's foe Bi-Beast. Justified, since he's an android.
- The EC Comics 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.
- The Powerpuff Girls story "Triple Threat" (Cartoon Network Block Party #58) has Mojo Jojo using a ray that initially seemed to have destroyed the girls, but actually makes them grow into a three-headed entity in a single body.
- One-shot comic The Carneys from Archie Comics, where a circus family have a siamese sisters named Linda-Louise, who are a two-headed girl.
- Legends of the Dead Earth: Subverted in Action Comics Annual #8. Phisto, the two-headed Bizarro World security guard who turns out to be collaborating with Zarn terrorists, has one mind and his two heads are in perfect sync. They always either Speak in Unison or finish each other's sentences.
- George and Tail, recurring characters from the marginal comic strip of Cricket magazine, are the independently-sentient head and tail of one earthworm.
- In Abraxas (Hrodvitnon), Vivienne Graham and San have this after their transformation into a Two Beings, One Body Kaiju, with their merged form having two heads which house either of their minds, similar to Ghidorah's three heads before them. In their first 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 second transformation.
- The Bridge: Grand King Ghidorah might seem to be this at first as he can speak out of each of his three heads, but is ultimately an aversion when it's found targeting the heads doesn't do much. The reason he can suffer massive damage to, or even lose one of his three heads is because none of them actually contain a brain. Bizarre Alien Biology is used as a reminder he's not a dragon like the Equestrian dragons, but an alien Animalistic Abomination that resembles a dragon. His actual brain, or rather equivalent, is in his chest.
- The two-headed Hideous Gobblsnutch in Captain Proton and the Planet of Lesbians.
"Ohhhh, I don't know..." said Left Head, quivering with fear and indecision.
"Can't you make up your mind for once?" snapped Right Head.
"How can I when I've got two of them!"
- Meet the Heavy Heavy Heavy.
- In the "Dark Woods Circus" series of Vocaloid PV's, Rin and Len Kagamine are confined to a mental institution and later have their heads chopped off and sewn onto one body.
- Kaiju Revolution: 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 Blood Knight who will lash out even against the center's wishes, the left head seems to be self-loathing due to it's tendency to nip at his body in disgust.
- The Legend of Spyro: A New Dawn: The Big Bad Deadlock is a three headed dragoness, each of which have their own personality and mind. Justified, as she's not technically one dragon, but conjoined triplets. Originally her three heads did bicker and fight, which is where her name came from, but eventually developed telepathy and now her heads get along well. This makes her quite dangerous, as each head is a different element and can mix and match them as a result.
- In ibenz009's 2020 Liliraune TF comic, besides the two main protagonists getting transformed into a Liliraune (which has two humanoid bodies with separate minds sprouting from a single plant), the plant's two flowers themselves seem to have independent minds based on the final panel.
- In the Pony POV Series, the 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 Queen Majesty, each head is also shown having differing emotions and reactions, with one even sleeping while the others are fully awake.
- RealityCheck's Nyxverse: In Nyx's Family, after eating way too many fire opals, Garble 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.
- Quest for Camelot: 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 Disney Acid Sequence song about how much better their lives would be if they were apart.
- How to Train Your Dragon: 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.
- Hercules: Cerberus's three heads are shown fighting each other over a steak that Hades throws to them.
- Gallavants: The Vanterviper's heads not only bicker, they also sing about their woeful plight.
Vanterviper: Oh, I will cry, 'till the day I die,
Two heads ain't better that one!
- The Little Prince And The Eight Headed Dragon: 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.
- The LEGO Movie: Bad Cop/Good Cop doesn't have two heads, but two faces, each with drastically different personalities.
- Monsters University 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.
- Dobrynya Nikitich and Zmey Gorynych: Zmey Gorynych. Despite being referred to in the singular, 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.
- Gandahar: Several of the Deformed have extra heads. Their leader has five, and at least two of them have different voices and personalities from his main head.
- Three Headed Shark Attack: The different heads of the shark occasionally nudge irritably at one another, or try to snatch the same human victim away from one another like competitors.
- Three Headed Monster: 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 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 Godzilla franchise — his three heads don't seem to have any distinct personalities from one another.
- Played Straight by his MonsterVerse incarnation in Godzilla: King of the Monsters (2019), 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 Hot-Blooded Blood Knight, and the left head is a Psychopathic Manchild with a short attention span that often annoys the middle head. His Red Baron 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).
- If you watch Fluffy the three-headed dog from Harry Potter and the Philosopher's Stone carefully you can see that one head is paranoiacally alert, one is lazy smart-aleck, and the third is a Cloudcuckoolander.
- In The Hitchhiker's Guide to the Galaxy The Movie, 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!
- The main antagonist in Jack the Giant Slayer 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 much less intelligent. Despite all this, the two heads seem to get along just fine.
- Monty Python and the Holy Grail: The Three-Headed knight. The heads start out speaking in unison, but once one of them breaks synchronization, the three start arguing about whether to kill 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.
- The Phantom Menace: Fode and Beed, the two-headed Troig announcer , 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.
- This trope is deconstructed in a HoloNet News story in Legends. Said story features a Troig named 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, 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.
- In Spider-Man 2, Dr. Octopus performs his nuclear fusion experiments with the help of four robotic tentacles which are attached to his spine, so that he can control them with his mind. Their artificial intelligence is so advanced that he had an inhibitor chip included to make sure that he could control them, and not the other way around. The inhibitor chip gets destroyed when his demonstration goes wrong, which allows them to assert their own personality and persuade him to start committing crimes in order to restart his research. In his dialogue with the arms it looks as if hes got four mechanical serpents all whispering toxic advice in his ear.
- Book of Imaginary Beings: The hundred-heads was a fish with a hundred distinct heads, each from a different animal.
- Dreamspeaker: Sisiutl is a size-changing snake with a head at both ends of its body.
- Joe-Jim the two-headed mutant from the Robert A. Heinlein novel Universe is one of the earliest modern types, and probably the first to be specifically described as a mutant
- The Hitchhiker's Guide to the Galaxy:
- Zaphod Beeblebrox fluctuates between being one and two people, according to the Rule of Funny. 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 And Another Thing... (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 Harry Potter background book Fantastic Beasts and Where to Find Them. 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 Caustic Critic, so the middle and left heads often team up to bite it off.
- The Brothers John from Abarat. And yes, one of them is a Jerkass who always bickers with the others. Clive Barker has stated that he intends to give them similarly conjoined love interests in a later volume.
- 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.

- In one of G. K. Chesterton'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 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 A Canticle for Leibowitz, and is an important plot point both times. The two-headed mutant who 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.
- Journey to Chaos: The true form of 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.
- In Starlight and Shadows, Zz'Pzora is a mutant Deep Dragon with two heads.
- In The Nutcracker and the Mouse King, the story that inspired the classic play The Nutcracker, the eponymous Mouse King has no fewer than seven heads.
- Downplayed in A Song of Ice and Fire and its adaptation Game of Thrones, where the Targaryen house sigil is a three-headed dragon. No real multi-headed dragons appear in The 'Verse, but it symbolizes a Rule of Three motif that recurrs with Daenerys, the most prominent Targaryen in the story. It also serves as an analogy to her three (separate, one-headed) dragons.
- Ology Series: 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.
- The Aquabats! Super Show!: "Ladyfingers!" features a siren with three heads named Quera, Hera and Vera. While Hera and Vera are evil and plot to devour the Aquabats, Quera ends up falling for Ricky Fitness and turning good.
- Buffy the Vampire Slayer. Becomes the subject of a Visual Pun when Spike takes on a reptile demon.
Spike: All right, heads up! [demon lifts up three heads; Spike gets an Oh, Crap! look] Heads it is then.
- In the Angel spin-off, 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.
- Doctor Who:
- Time Lords can apparently end up like this if a regeneration goes really wonky, although we've yet to actually see this. The Ninth Doctor claimed he could have two heads ("Or no head!") before regenerating, and the Eleventh mentioned a two-headed godmother.
- "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.
- Groundling Marsh: Had Mud/Slinger, a two-headed Groundling, each being their own distinct person.
- The TV version of The Hitchhiker's Guide to the Galaxy 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 not terribly successful.
- In a dream sequence in I Love Lucy, Lucy imagines her neighbors Fred and Ethel as a bickering two-headed dragon.

- In the The Librarians "and the Tears of a Clown", Eve is transformed in a two-headed woman as part of a freak show. Her second head is more irreverent and a bit lecherous that the original.
- Power Rangers:
- In one episode of Mighty Morphin' Power Rangers, the Monster of the Week 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.
- In the fairy tale episode of Scrubs, an inseparable couple is described as a two-headed monster.
- The Twilight Zone (1959): In "Mr. Dingle, the Strong", the Martian scientist's two heads each have their own personality. They seem to get along well.
- Multi-headed kaiju appear in some Ultra Series:
- Pandon, the final enemy in Ultraseven, is the best known example in the franchise. In some series, he has two heads on a single neck, making him more of a Two-Faced monster but in others, the heads are on separate necks. It's been stated that the left head is male and the right head is female, but that doesn't really matter when the Ultra heroes are being seared by twin jets of fire from a kaiju as formidable as Pandon.
- Each of Fire-Draco's three heads in Ultraman 80 has their own personality, appearance, powers, and even human form (the mortal reincarnations of the monster after its essence was sealed away centuries ago). The central red head appears as a fire-eater and possesses a flaming Breath Weapon; the left head is blue and can bash 80 with his thick skull due to his human form being a strongman; and the white head on the right is reborn as the young descendant of the priest who originally defeated Fire-Draco and is the Token Good Teammate forced to help the other two heads' reincarnations regain their original form.
- Jashrine from Ultraman Mebius has three heads stacked like a totem pole, each with their own emotion motif and powers. The top head is angry and wields a giant Battle Boomerang; the middle head is happy and a straightforward martial artist; the bottom head is sad and uses telekinesis. However, only one head at a time can act and speak, and they often finish each other's sentences as the active head changes.
- The same series also has the Dinozaur, which has only one head, but two tails. But if you destroy the monster's head, the tails will grow into heads and the entire body will flip over, becoming a Dinozaur Reverse.
- The Whose Line Is It Anyway? game "Three-headed Broadway Star" has three players join together and sing a fictional Broadway song, one word per head. This commonly leads to non-sequitur mishaps.
- The eponymous conjoined twins of the fictional band Evelyn Evelyn usually get along fine, but their self-titled song "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.
- Insane Clown Posse 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"!
- Many 1960s Psychedelic Rock albums like to portray multiple headed gods on their album cover, inspired by Hinduistic and Buddhistic art. Examples are Jimi Hendrix' Axis: Bold as Love and Anthem of the Sun by The Grateful Dead.
- This is invoked in the Vocaloid songs "Wide Knowledge of Late Madness" and "Dark Woods Circus". Two twins are spliced together and forced to join a freak-show.
- Slavic Mythology: 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, whose heads represent heaven, earth, and the underworld.
- The poem "Us" by Shel Silverstein; something of an extreme example, as the accompanying drawing shows two faces stuck onto the same head.
- Tuatha from The Fallen Gods 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.
- Welcome to Night Vale:
- 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 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.
- Tom, Dick, and Harry from The Muppet Show. They disagree about who's in charge of the... er... group?, what their intended act is, and such. Also, according to Harry, Dick is female.
- Theres a two-headed monster in Groundling Marsh 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.
- The fifth series of John Finnemore's Souvenir Programme features a song by 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 Sympathy for the Devil song (though Cerberus is not exactly a "Devil" except to people who don't portray him correctly) in which Cerberus laments that people don't show the Big Friendly Dog some kindness and affection instead of just fighting him all the time.
"They stab or slash or try to choke him,
They don't pat him, they don't stroke him,
No, not the tiniest amount!
No-one squeaks his squeaky toy,
No-one tells him he's a good boy,
Or three good boys, depending how you count!"
- Dungeons & Dragons:
- The Demon Prince Demogorgon, whose heads allegedly have competing spy networks and who constantly scheme against each other. They also have individual names — Aameul and Hethradiah; Aameul favors plans that use deception, while Hethradiath favors unsubtle raw power. Oddly enough, Demogorgon often benefits from this rivalry; one popular legend states that Aameul made a bargain with a lich queen, making her unprepared for a vicious pre-emptive strike by Hethradiah's forces; as a result, she was slain, giving Demogorgon as a whole her lands, wealth, and resources.
- Ettins are a race of two-headed giants. In early editions, one head (usually the one on the right) is usually the dominant one, so they rarely argue. In 5th, however, the two heads rarely get along, spending most of their time arguing and insulting one another like bickering siblings. Each head has its own name, and the ettin is usually referred to by a compound of these names. A 3rd Edition adventure features 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.
- The Angry, a type of sorrosworn embodying anger and hostility, have two heads each, which constantly bicker and argue with one another until they find something else to vent their wrath on.
- 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.
- 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.
- Death dogs are giant two-headed dogs with a nasty bite that lowers maximum hp indefinitely until the effect is cured. However, both heads are sapient and the monster manuals of all editions they appear in suggest they can be avoided if the player can start a conflict between the heads.
- Dread linnorms have two heads, each with a different Breath Weapon — one head breathes fire, the other ice.
- Pathfinder: Many creatures have extranumerary heads, each with its own consciousness. While this is a minimal issue in instinct-driven animals, it results in interesting intrapersonal dynamics in more intelligent beings.
- Vydrarchs and elder wyrms both have two heads, which for the most part act in concert but have been known to talk and even argue with one another. Jotund trolls have nine heads, which invariably all bicker with each other (usually about who gets to actually taste their prey).
- Magdh of the fae has three faces, 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.
- Chimeras are unique for not having different mind in each brain, as their lion, dragon and goat heads act in concert and share a single will.
- Ettins are two-headed giants whose heads often argue with one another and need to agree on common plans of action before doing things. A religious sect of ettins, the Children of Balance, seeks to deal with these issues by fostering balance between opposing viewpoints, ensuring cooperation between their selves while benefiting from diversity of thought and outlook — their leader, for instance, has a Neutral Good head and a Neutral Evil one. They chiefly worship and try to emulate dualistic deities as a result, such as the goddess of life and death, the god of creative and destructive magic, and the god/dess of the sky and the sea.
- Mukradis are immense centipedes with three heads, each of which possesses a different Breath Weapon — fire, lightning and acid.
- Neothelid overlords have two heads, a manifestation of the minds of two powerful neothelids struggling for supremacy after one devoured the other.
- Games Workshop games:
- Examples present in Warhammer 40,000, Warhammer and Warhammer: Age of Sigmar:
- Kairos Fateweaver, a Greater Daemon of Tzeentch, the 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 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.
- Warhammer: When a daemon possessed the great dragon Galrauch, the Gold Drakes head and neck split down the middle creating two ferocious heads. The possession wasn't complete, however, and Galrauch's original personality will sometimes emerge to take control of one of the heads and attack the other.
- In Warhammer: Age of Sigmar, the God of Destruction Gorkamorka has two heads due to being a fusion of the orc brother gods Gork and Mork from the-world-that-was. They stay as a composite being until they get to arguing with one another, which happens often, at which point Gorkamorka splits back into his component selves.
- In Blood Bowl, 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.
- In 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 fire two pistols at the same time as each head is able to aim and fire one of the guns.
- Examples present in Warhammer 40,000, Warhammer and Warhammer: Age of Sigmar:
- Magic: The Gathering 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 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."
- The Spikit, a double-headed beast of burden.
- Rahkshi Kaita Za, the combiner model of Turahk, Lerahk and Kurahk.
- Two-Bad of Masters of the Universe fame. In fact, in the 2002 cartoon, they devoted an episode to explaining how they came to exist and another episode to their scheme to become separated from each other.
- In Flush Force, there is the Gruesome Twosome team, made up of two-headed animals.
- Crayon Chronicles: One of the characters you can encounter is a two-headed female troll.
- HEPH: A trailer shows an enemy type that has two heads attached to each other.
- The Legend of Zelda: A Link to the Past: The boss Trinexx is a giant tortoise with three heads; a central one, a blue one that breathes ice that leaves frozen trails on the floor, and a red one breathes fire. The two elemental heads get cut off over the course of the battle.
- Ninja Clowns: Twisto is a three-headed hydra clown.
- Nosferatu Lilinor: One of the bosses of the game is a three-headed Hydra.
- 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, a notable aversion of this trope that only has a brain in the middle "main" head. The other two heads behave more like its hands.
- 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.
- Weezing has two heads, which produce two different toxins. According to the Black/White dex entry, triplet Weezings also exist, but they are very rare.
- Vanilluxe and the Klink line from the same generation also have multiple heads. In the case of Vanilluxe, they're the results of a pair of partially melted Vanillish re-freezing overnight.
- 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.
- Subverted by Binacle. Although its two barnacles attached to a rock, they can detach and move to another one. Then there is its evolution Barbaracle, who's made of seven barnacles, four of which form its arms, another two its legs, and one for its "head". They usually follow the head's orders.
- Project Dimentia Bodhisattva:
- Aqua can convert herself into a two headed girl when pressing down, and can get three heads if she was in the level Sky Chasm at max level.
- Orphyll from temtem has three heads, each with a different expression. The one on its left hisses, the one in the middle looks serious, and the one on its right is a Perpetual Smiler.
- For the classic two-headed ogres, it's very much Depending on the Writer. In the RTS games, it's Played for Laughs, as they invariably argue with each other. Some keep this in World of Warcraft, but not always. 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", and the ogre king Imperator Mar'gok deliberately averts this.
- 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 Brick Joke in Heroes of the Storm, as described below.
- 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 That One Boss for groups that bring a lot of squishy characters.
- 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.
- In Heroes of the Storm, the Ogre Mage Cho'gall is a playable character. Unlike the other characters in the game, Cho'gall requires two players to control, with one player controlling Cho (a melee warrior who also controls the body) and Gall, a spell caster. Naturally, they're based on Combination Attacks between the two players.
Cho: I'm ready to serve, my master!
Gall: I—I... I'm not ready.
- Within Warcraft the two heads had distinct personalities. Cho is the mastermind and main voice while Gall is insane and chants near gibberish with each line Cho speaks.
- Notably averted with the two-headed ettins, at least until Legion where a single quest mob will argue with himself.
- Many of the angels in the Bayonetta series are a notable aversion of this trope. All of them are Eldritch Abominations, 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 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.
- 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 Kingdom of Loathing, the Boss Bat has two heads. So does a mini-boss, a two-headed zombie, which even references the Boss Bat fight.
- In 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.
- Quest for Glory: Whilst they all agree on the fact they're not going to let the Hero of Spielburg, The Prince of Shapeir, The Saviour of Fricana, 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 Star Ocean: The Second Story 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 Arcuz is a two-headed giant who is/are elder brother and younger brother.
- In the game Eric the Unready, 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 Ultima VI. It resides in Blackthorn's Castle. This is a Shout-Out to Doctor Dolittle.
- 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.
- The Ettin in Stonekeep has two heads with very distinct personalities.
- Digital Devil Saga 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."
- Super Mario Bros.:
- Plants vs. Zombies 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. In the end, they agree to explodonate.
- Kid Icarus: Uprising 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 Day of the Tentacle the three protagonists appear to get turned into a three-headed hybrid by a time machine accident. It later turns out they had simply gotten stuck inside one set of clothes.
- Ninja: Shadow of Darkness: 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.
- There's a two headed shopkeeper in Simon the Sorcerer 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.
- Billy the Brute from an Ettin in Wizard 101 acts similar to the Ettins from Dungeons & Dragons. His right head is the dominant and more intelligent of the two and has to remind the left who's friend and who's food. He's also a great stonemason.
- ToeJam & Earl: 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.
- Tak and the Power of Juju has the redneckish Two-headed Juju. The left head is named Rufus and the right one is Jerry.
- Jade Empire features the Minion of Suffering, who is humanoid, but has two cow's heads.
- Landia in Kirby's Return to Dream Land 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 The Dragon from Heroine's Quest: The Herald of Ragnarok.
- The game Star Command: Revolution has a Brain in a Jar 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.
- Herbert and Chauncey from The Ultimate Haunted House 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 Non-Malicious Monster or Laughably Evil depends on the mood of the house.
- Mordheim: City of the Damned has a partial example played for Body Horror. The Extra Face mutation gives a Chaos fighter 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.
- Killer Instinct has the unusual case of Eyedol, who had two separate heads in the original KI while the reboot gave him two halves of a head, thanks to Gargosnote . Despite this, the reboot version fits the spirit of the trope better; he uses a Stance System based on which head is awake (one is a rushdown character, the other is a zoner), the player can change styles by punching the sleeping head until it wakes up, and his 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).
- In 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.
- Brickhead "Bricks" Mulligan, the color commentator in Mutant Football League, 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 directly onto Bricks.
- Clover from Deltarune, 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 Shrinking Violet. They do agree on some things, though, and the trick to ending the fight with them is to get them talking about those subjects.
- Miscreated has two-headed dogs as an enemy type.
- The two faces of the female mutant in KKnD 2 do not get along.
- Mega Man
- Viva Piñata has the Twingersnap, a version of the Syrupent with A Head at Each End, acquired by whacking a Syrupent egg with the shovel the moment before it hatches. Doing the same thing to a Twingersnap egg gets you a Fourheads, which has, well, four heads - three in front and one on the tail.
- One of the rarer mutations in Wobbledogs allows dogs to have extra heads, so they can bark much more often.
- The Nakarkos of Monster Hunter is one of these made from bones... 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.
- Ghost of the Gulag: Iosef and Grigori are a two-headed psychic boar Blind Seer. The two heads are partly fused and share a single central eye which grants them psychic abilities, though while Iosef sees Shadow Walker as a bringer of death Grigori sees him as a restorer of balance. Interestingly, the two boars seem to be of different species as well: Iosef is a Babirusa while Grigori is a European Wild Boar, and are divided in th middle between brown-furred and hairless.
- Girl Genius: One of the first few strips shows the discarded experiment of a Mad Scientist, with one male and one female head, panhandling on a street corner with a sign saying "can't agree on a hat..."
- The Order of the Stick:
- The chimera Trigak. It has a dragon's head, a lion's head and a goat's head, each of which can talk; whether they have different personalities is unknown, since Belkar kills it shortly after it appeared.
- Also appears as a Funny Background Event, when 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 5 heads seem to be equally angry, given that all five roars are coming in through the phone. As do each of her five elemental breath weapons.
- Yet Another Fantasy Gamer Comic:
- The Chimera: the dragon head is 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 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.
- Partially Clips: The Paradox Dragon (archived link) parodies the Knights and Knaves puzzle, with the dragons' three heads being unable to even agree on the rules, squabbling until it died of a migraine.
- Dungeons & Denizens: Donna and Diana are 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).
- 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.
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.
- 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.
- Spinnerette: Minerva the 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 Issue #9. They also wind up a bit distracted thanks to a Hate Plague in Issue #13.
Middle: I knew this dress was too short...
Left: Compared to the metal bikini?
- Contemplating Reiko: 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.
- In Commander Kitty, Zenith's biggest and baddest monster has not only a giant bear head, but a pair of dragon heads for arms.
- 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 thinking out loud.
- Slightly Damned: 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.
- Dreamscape: In the flashback in "A Curse or a Blessing", Melinda's curse's dog form has 2 heads.
- Multiple instances in Neopets:
- Available to raise is the Mutant Hissi, a two-headed snake pet. Though they behave as one under the player's care, the "Tale of Woe" plot features one that shows the separate heads do have separate personalities. In a parody of the Knights and Knaves puzzle, one of the two heads always lies and the other always tells the truth, but you never even get the chance to ask them a question because they're too busy arguing to notice you. The solution to this puzzle was to find a pointy stick and jab them with it; the one that says it didn't hurt is the liar.
- The Bearclops is a Petpet with one head of a Bearog — a dog critter — and one head of a Meowclops — a cat critter. In their artwork, they're visibly fighting like... well, cats and dogs.
- All of the vertebrate-analogues on 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 Belly Mouth 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.
- Subeta has Experiment #4423, a two-headed lizard critter able to obtain from the lab. Reginald and Bartholomew are a 4423 in charge of the option to swap two pets' names.
- In Tales of MU, Sara and Tara Leighton were fused together in a teleportation accident and now have their heads on one shared body.

- In The Avengers: United They Stand, Gemini from The Zodiac is depicted as a two-headed alien (one male head and one female head) with four arms.
- The Baskervilles: 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.
- Beany and Cecil went on the search for the Three-Headed Threep. The original series and the 1988 reboot featured an episode about the Threep.
- In the Biker Mice from Mars episode "Too Many Limburgers Spoil the Cheese", Greasepit at one point meddles with Karbunkle's duplicator ray, which causes him to gain a second head that he bickers with for the rest of the episode.
- Agatha and Emily, the two-headed vulture from the Bugs Bunny cartoon "Transylvania 6-5000." She gets along quite well with herself. Also Count Bloodcount, after Bugs transforms him into their Spear Counterpart.
- In the Camp Lakebottom episode "Head Two Head", Suzi and Gretchen accidentally get fused together into a two-headed being with big muscles and long necks.
- Captain Star: Atomic Stoker "Limbs" Jones has nine heads . . . as well as six arms.
- Not only does the title character of 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 Conjoined Twins, not two heads on one creature.
- The Son of the Chicken from Outer Space from Courage the Cowardly Dog 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.
- In Darkwing Duck, Morgana's relatives are all monsters, including a two-headed vulture-like creature. When DW and his family meet the extended family at their villa, one of the heads wants to eat them, but the other objects, saying it would be rude to eat guests. (Unfortunately for Darkwing, Morgana's grandma sides with the first one.)
- Dexter's Laboratory: During Dee Dee's Derailed Fairy Tale 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.
- The Dr. Zitbag's Transylvania Pet Shop episode "Easter Funny" had Officer Deadbeat work with a two-headed rookie cop. One head was peaceful and mellow, the other head was aggressive and ill-tempered, and neither of them got along very well.
- Dragon Tales
- Zak and Wheezie 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) Fridge Logic to be addressed.
- One episode features a cat with a head at each end. One head only says "me," and the other says "ow."
- Duckman's conjoined sons Charles and Mambo.
- In an episode of Dungeons & Dragons (1983), Presto has to deal with a three-headed ogre who is hustling money with a Shell Game (using skulls and a marble). The Trope is subverted; not only do they cooperate, they do so very well.
- In the infamous Ed, Edd n Eddy Mind Screw episode "One+One=Ed", Rolf shows up as a three-headed version of himself. Though by this point, the Eds had seen so many weird things in this episode that Eddy hardly bats an eye.
Eddy: A three-headed Rolf... Yawn!
- In the Family Guy episode "Road to the Multiverse", one of the Alternate Universes is a world where all the characters have two heads, one happy and one sad. Stewie's two-headed counterpart has no problems kissing himself.
Happy!Tom: The President's dog just had puppies!
Sad!Tom: There was a plane crash.
- Filmation's Ghostbusters 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.
- "Put Your Head on My Shoulder" has Fry's head sewn onto Amy's shoulder.
- We also see a dog with heads at both ends. The vet mentions that one needs to take pills, the other needs a suppository. A goat with heads at both ends appears in another episode.
- In Garfield and Friends/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. Different personalities? Check. Arguing with each other? And check.
- On The Grim Adventures of Billy & Mandy, 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 were immediately attracted to Mindy's chihuahua Little Delicious, and exchanged glances of dismay when they realized the middle head was growling at her.
- Crygen and Pyre, the two bickering halves of Magnokor on Inhumanoids, sometimes merged into a two-headed and still-bickering form.
- He-Man and the Masters of the Universe (1983) and She-Ra: Princess of Power features Two-Bad and Multi-Bot who fit this trope. Horde Prime is implied to (sort of) fit this trope too.
- In an episode of Jackie Chan Adventures, Jackie gets a Jekyll & Hyde split which isn't completed, resulting in his Yin and Yang splinters being two heads atop one body which control either half of the body. He eventually gets fixed.
- In one The Jetsons 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.
- On Jimmy Two-Shoes, demons with two or more heads make up a few of Miseryville's denizens, and one episode even had a Cute Monster Girl made of three separate bodies on a single waistline.
- In the Johnny Test episode "Li'l Johnny", Johnny runs into Susan and Mary's lab to find them as two heads on one body. Their expanation? Don't ask!
- A character named Cindy was this in Lloyd in Space. 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.
- In Men in Black, Alpha's first One-Winged Angel 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. 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 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.
- My Little Pony: Friendship Is Magic:
- "Feeling Pinkie Keen" sees the girls getting attacked by a four-headed hydra. 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 — and at one point laughs at the others when their attempts to grab the ponies just earn them concussions or mouths filled with trees and rocks.
- "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.
Tiger Head: You've got no idea what it's like to have a sister constantly looking over your shoulder!
- The aptly-named Three-Head from The Neverending Story: The Animated Adventures of Bastian Balthazar Bux, whose three heads take turns at emerging from small slots in his shoulders and display distinct colors and personalities.

- Planet Sheen has Princess Oom. One face is a bubbly cheerleader type and the other is an intense seductress. Both are in love with Sheen.
- Popeye the Sailor Meets Sindbad the Sailor includes a two-headed giant named Boola. Although they mostly act as one unit for the bulk of the episode, at one point they let Popeye go when the two heads get distracted by their bickering over how they want to eat him and start slapping each other.
- Porky in Wackyland: Porky Pig encounters a three-headed creature whose heads bicker and argue. Each head also has a distinct haircut, with one having a bowl cut, one with a messy mane, and the third being bald.

- The Simpsons Treehouse of Horror 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. Parodied in The Stinger with Homer complaining that this means he often has to cancel favorite activities in order to meet Mr. Burns' business obligations.
- A later Treehouse of Horror had Bart's head being grafted onto Lisa's body when he decapitates himself with the string of his kite. At the end of the segment, they both get their heads cut off at a sawmill, and Lisa's head is grafted onto Krusty's body while Bart's is grafted onto Selma's.
- In a segment of the twenty fifth Treehouse of Horrors. Bart reads Aramic that was written on a desk in Springfield Elementary. As the result, he and Lisa are transported to another school which is located in Hell. The principal has two heads.
- In the SpongeBob SquarePants episode "SB-129", Future Patrick has two heads.
- One episode of Stripperella featured squabbling conjoined twin brothers, who shared a single body and each controlled one arm and leg, essentially a two-headed man. The two of them had wildly different personalities (a laid back American and an uptight Brit), and almost nobody, including the brothers themselves seemed to be even aware that they shared a body; for instance, one woman claimed to have dated one head for months without meeting the other, and one head claimed to be two years younger than the other.
- The 1960's Depatie/Freleng cartoon show The Super 6 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. The Matzorileys were originally the antagonists in the first Inspector cartoon, "The Great DeGaulle Stone Affair."
- The Bulldrafish from Tak and the Power of Juju. Each head has its 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 belongs to Dr. Bender, a hideous Mad Scientist; the other belongs to Fender, an oafish Surfer Dude 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.
- Triple Threat from 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.
- Tenko and the Guardians of the Magic: Villains Janna and Jason can perform a Fusion Dance into a two-headed dragon, with each of them in control of one head.
- Touché Turtle and Dum Dum: The plucky turtle and his assistant battle a two-headed giant in the episode "Giant Double-Header."
- The version of Blitzwing from Transformers Animated 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 Transformers Energon 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 Voice of the Legion - 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.
- Transformers: War for Cybertron Trilogy also features Quintessons with five faces, each of which has its own individual personality, and they must all agree to reach consensus to finally partake an action. However, one face of one Quintesson has had enough with his other faces disagreeing with him, which culminated in him cutting off his four other faces, leaving only one remaining in charge.
- Another humorous example would be an extra from The Transformers, 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 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 Beast Wars Neo — 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 Transformers: Prime "Beast Hunters" toyline features a Sinnertwin lookalike known as Twinstrike.
- The same toyline also brings back Hun-Grrr as a twin-headed dragon.
- Cyberverse's take on the conjoined Autobot twins Rack'n'Ruin comes off as this.
- One Underdog short has him facing a two-headed dragon which would stop to shake hands with itself chanting "Teamwork, teamwork, that's what counts!"
- Red Mantle and Dragoon from The Venture Bros. A recently-joined pair (forced when Dragoon was dying after a tussle with Phantom Limb) who argue constantly over which of them is actually in charge. Thus far, Dragoon has taken over the left side.
- Ted and Tina Twingersnap from Viva Piñata.
- In the Wander over Yonder episode "The Legend", one of the kids Wander and Sylvia rescue from Lord Dominator's Mecha-Mooks is a pair of conjoined Polar Opposite Twins, scrappy Jamie and Lovable Coward Hank.
Jamie: I'll scramble their circuits!
Hank: I'm too young for half of me to die!
- Byron and Beasley from What It's Like Being Alone are blue-skinned conjoined twins. The former is constantly picking on the latter.
- Truth in Television with dicephalic conjoined twins 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 driver's license, they had to take the test twice. They may be conjoined but they are two individuals, if not exactly separate, people. It does make one wonder what would have happened if only one had passed the test.
- Octopuses function similarly to this trope; each of an octopus' eight arms has its own cluster of neurons that essentially serves as a simple brain. Each arm has enough "intelligence" to perform simple tasks that are "assigned" to it via the octopus' main brain, though doesn't have enough independent thought to play this trope straight.
- 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.
