Me and him
—Shel Silverstein, "Us"
Whenever a creature has two (or more) heads and the ability to talk, each head will have its own distinct personality. In more comedic series, the heads will often argue with each other over which course of action to take.
- This commercial for Leapfrog's Leapster.
Anime & Manga
- Ebonwumon of Digimon Tamers, who has different accents in the dub.
- 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.
- 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.
- Rouge in Ranma One Half, having fallen in the Spring of Drowned Asura, has three faces (all on different sides of the the same head) when she turns into her Goddess form. They bicker endlessly with one another, even yelling at each other to wake up if one of them is knocked out.
- The giant Judge Baskerville in One Piece 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 Axe Crazy. Subverted when it's revealed to be three different people with very odd physiques.
- 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.
- Inu Yasha 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.
- 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 attacked the other.
- Double-Header of the Legion of Substitute Heroes in The DCU -- pictured above.
- Doubleheader was also the name of a gangster with two heads in Fighting American Comics.
- And a member of the new X-Men in Earth X named the Two-Headed Man.

- Green Lantern
- One of the newest members of the Sinestro Corps is a two-headed alien. Both heads are psychotic killers but one likes killing people by ripping their bodies apart, while the other is disgusted by such crude methods and prefers more subtle methods of killing. They fight over who should control the Sinestro Corps power ring after they get it. And later, when the Green Lanterns assigned to tracking down and capturing the Sinestro Corps rings find some of their handiwork, the fact some of the bodies have been torn apart violently while others have been killed by precise controlled blasts hints that they are still fighting over control of the ring.
- There's also Maash, who has three heads (stacked vertically), the topmost being an innocent man and the bottom two both being cruel psychopaths.
- A four-headed, multi-limbed creature formed from the remains of four teenage boys is sent to kill John Constantine in one issue of 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.
- 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.
- Bi-Beast, an Incredible Hulk foe. But he's an android, so yeah.
- George and Tail, recurring characters from the marginal comic strip of Cricket magazine, are the independently-sentient head and tail of one earthworm.
Films -- Animation
- Devon and Cornwall, the two-headed dragon in the animated film Quest for Camelot. They/he can't fly unless both heads can agree, which isn't often.
- The Mayor of Halloween Town from The Nightmare Before Christmas for some reason actually has a smiling face on one side of his head, and a frowning one on the other.
- Chunk from Toy Story 3 has a face that can flip between a smiling one and a frowning one by pressing a button on top of his head. During most of the movie, Chunk will always show his frowning face to show his affiliation to Lotso, but at the end of the film due to Lotso being removed from the daycare center, Chunk actually now decided to show his smiling face.
- The Vanterviper's heads in Gallavants not only bicker, they also sing about their woeful plight.
Films -- Live-Action
- The Three-Headed knight from Monty Python and The Holy Grail. They all agree that they want to kill the travelers, but bicker so much about what to do after that... that the knights get away.
- Fodesinbeed Annodue, the two-headed announcer from The Phantom Menace, 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. Perhaps that particular announcer was chosen because he could easily and fluently speak both. At the same time.
- Averted with King Ghidorah from the Godzilla franchise. His three heads don't seem to have any distinct personalities from one another.
- Played straight with the Monsterverse version. According to the director of Godzilla: King of the monsters each of King Ghidorah's head has it's own personality with the center being dominate.
- Scrad & Charlie from Men in Black 2.
- Classic B-movie The Thing with Two Heads plays this seriously. Or at least they try to.
- In Spider Man, the four tentacles of Dr. Octopus have a distinct personality from Octavius himself.
- In The Hitchhikers 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.
- Fallon, the lead giant in Jack the giant slayer. Each head even had it's own voice actor.
- The Hitchhikers 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 Pierson's Puppeteers in Larry Niven's Known Space universe both play this straight and subvert it in that they have two heads, but the brain is in the central body.

- 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.
- 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 fairy tale episode of Scrubs, an inseparable couple is described as a two-headed monster.
- In a dream sequence in I Love Lucy, Lucy imagines her neighbors Fred and Ethel as a bickering two-headed dragon.
- 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.
- Lexx: Robot head 790 has himself sewn to the shoulder of a largely mindless cyborg drone, with whose mutterings he grows so annoyed that he punches himself in the other face.
- In the Doctor Who episode "The Time of Angels", the Doctor tells an anecdote about a planet of two-headed people.
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. [...]
- Of course, this relaxed conversation becomes extremely important later in the episode...
- Buffy the Vampire Slayer. Becomes the subject of an Incredibly Lame Pun when Spike takes on a reptile demon.
"All right, heads up! [demon lifts up three heads. Spike gets an Oh Crap look] Heads it is then."
- 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.
- Insane Clown Posse mention this in the song "Down With The Clown"
"What if I grew another fuckin' head?
- As quoted above, the poem "Us" by Shel Silverstein; something of an extreme example, as the accompanying drawing shows two faces stuck onto the same head.
- The Two-Headed Monster from Sesame Street. "Mountains!" "Seashore!" or whatever the topic at hand is.
- 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.
- 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.
- Dungeons and Dragons
- Demon Prince Demogorgon, whose heads allegedly have competing spy networks and who constantly scheme against each other.
- The five-headed Tiamat is, however, an aversion.
- Ettins are a race of two-headed giants. One head (usually the one on the right) is usually the dominant one, so they rarely argue. There was, however, a 3rd Edition adventure that featured a human man who was turned into an ettin, with his mind in the left head and a new evil personality in the right head that was slowly taking control.
- In the template-heavy days of 3.5, there was "Multiheaded Creature", although it did put a reasonable limit on how many heads were added.
- Subverted with Geryon in 4th Edition. He has three heads, with one being thoughtful and conniving, one being angry and cruel, and one being manic and gleeful. However, they actually share one mind, never argue with each other, and normally only one will talk at a time, with the dominant head being determined by his emotional state.
- Jotund trolls in Pathfinder have nine heads which invariably all bicker with each other (usually about who gets to actually taste their prey).
- Warhammer has the first Chaos dragon, a good dragon that was corrupted by Chaos and grew a second head. His original personality is still in there somewhere and may attack the bad head during the battle.
- 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 Hydreigon, which subverts this trope by only having a brain in its center head.
- Exeggutor's 3 heads all think independently, though they never argue.
- World of Warcraft
- Not true for most two-headed ogres. Though there are very few of those you can actually talk to, they're mostly just smart guys and might as well only have one head. Draz'zilb even refers to himself as "I".
- Blizzard actually had an April Fools joke about the ogres, claiming that two-headed ogres would be playable in World of Warcraft as a sort of cooperative character. That is to say, two players each control a head, and both control movement. This being an April Fools joke, they of course emphasized all the features that made this playstyle incredibly inconvenient.
- In Warcraft 2 the heads would argue with each other if you kept clicking on them ("This way!" "No, this way!"). When they are upgraded to Ogre Magi, they start talking in unison, get their crap together, and learn magic powers.
First Head: We're not brainless anymore.
"You always hungry -- that's why we so fat!"
- 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 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.

- 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
- 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, and Twinbellows, a two headed Hell Hound.
- 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.
- 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.
- The chimera Trigak from The Order of the Stick. It had a dragon's head, a lion's head and a goat's head, each of which could talk; whether they had different personalities is unknown, since Belkar killed it shortly after it appeared.
- 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.
- Though even the Chimera isn't as bad as this hydra.
- There is also a small story arc about a couple of ettins having love troubles, since both heads of the female ettin like the same head of the male ettin but not the other. The male ettin ends up asking the Chimera for advice.
- This Partially Clips strip.
- Donna and Diana from Dungeons and Denizens. Two heads on one hellhound body, hinted to be the result of momma dallying with Cerberus. Distinct to the point of considering each other sisters... and romantic rivals for the attentions of the same orc (who wisely does his best to avoid them).
- DJ Tonja in Muertitos doesn't so much have two heads as a second mouth on the back of her head, but the second mouth has its own personality, and often argues with the front face.
Tonja: Could you at least stop eating while we're on the air? God, it's your fault we're so fat.
- Isp, Osp, and Mosp in Sluggy Freelance.
- The travelling merchant's bandersnatch in Digger has two heads, and although they're clearly distinct entities (the bandersnatch-unit is referred to as "us"), they pretty much agree about everything, and alternate speaking with each sentence.
- Minerva the Cerberus in Spinnerette has three heads, each one with its own look and personality. The left head is the cute one, the right head is the brash, fiesty one, and the middle head is the mature, moderate one. Interestingly, rather than being presented as three individuals sharing one body, it's more like Minerva is a single person who's thoughts are the same for all three heads, just filtered through different personality traits.
- Though we see her heads talking to one another a few times in the book-only Issue #9.
Middle: "I knew this dress was too short..."
- Zeni and Nadi Tweeling of Contemplating Reiko 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.
- Dr. Mercurious' webpage is proof that Rule 34 extends even here.
- 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.
- Two-Badd of He-Man and the Masters of the Universe fame. In fact, in the remake, they devoted an episode to explaining how they came to exist and another episode to their scheme to become separated from each other.
- Filmations 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.
- One of the Popeye two-reelers, Popeye the Sailor Meets Sindbad the Sailor, includes a two-headed giant.
- Not only does the title character of Cat Dog 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.
- 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.
- Sabrina and The Groovie Goolies also has a character with two heads.
- Zak and Wheezie from Dragon Tales 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 potential Nightmare Fuel filled) Fridge Logic to be addressed. When one (or both) of them wants to start dating, double-dating will be not only an option, but a necessity. This is ignoring issues of masturbation, as well. Unsurprisingly, Rule 34 has already explored that last item...
- Futurama "Put Your Head on My Shoulder" has Fry's head sewn onto Amy's shoulder.
- Charles and Mambo on Duckman.
- 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 does only have four faces. However, 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) Alpha Q's real self speaks in the Voice Of The Multitude - Alpha Q is eventually revealed as the combined consciousness of everyone lost in his planet's destruction.
- Another humorous example would be an extra from Transformers Generation 1, 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.
- This is averted in the Animated Adaptation of The Neverending Story, where a three-headed character never has more than one head "awake" at a time. In the book, it was four.
- Hanna-Barbera's 1960s version of Alice in Wonderland has a caterpillar with a head at each end, who just happened to look (and sound) like Fred Flintstone and Barney Rubble.
- Frank and Len from Ruby Gloom are a two-headed rock musician. Frank is smarter than Len, though not much.
- On The Grim Adventures of Billy and Mandy, Grim's three-headed dog doesn't talk, but his heads (two husky-types and one poodle) don't always act the same. Two of his heads were immediately attracted to Mindy's chihuahua Little Delicious, and exchanged glances of dismay when they realized the middle head was growling at her.
- In an episode of Jackie Chan Adventures, Jackie got influenced by a powerful magical pair of tigers and ended up with two heads, one very good and the other evil. They're actually his Yin and Yang, who showed up in the first season when he was split in two by one of the plot artifacts. The evil one is a pushy jerk, and the good one is a Lovable Coward who only fights reluctantly.
- 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.
- Agatha and Emily, the two-headed vulture from the Bugs Bunny cartoon Transylvania 6-500. She gets along quite well with herself. Also Count Blood Count, after Bugs transforms him into a male two-headed vulture. Agatha and Emily are delighted and chase him off into the night.
- Red Mantle and Dragoon from The Venture Brothers. 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.
- 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!"
- On Jimmy Two-Shoes, a two-headed man is one of the many citizens of Miseryville. He does not look out of place.

Happy!Tom: The President's dog just had puppies!
- 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!
- The My Little Pony Friendship Is Magic episode "Feeling Pinkie Keen" sees the girls getting attacked by a four-headed hydra. Amusingly enough, one of the heads appears to be a little slow on the uptake; the other three heads roar in unison, for example, but the fourth one doesn't join in until it realizes what the other heads are doing.
- 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.
- The 1960's Depatie/Freleng cartoons 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.
- 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 drivers license, they had to take the test twice. They may be conjoined but are two individual, if not exactly separate, people. It does make one wonder what would have happened if only one had passed the test.
- Two-headed turtles: they will fight their other heads over food, and they're uncoordinated.
- Two-headed snakes too. Like the two-headed turtles, they will also not slither very well, and they'll fight over food and have been known to try to eat each other.
