Those two are joined at the hip.


I've had twice the adventure

I've cried double the tears.

I've had two times the bad times,

In only half the years...

We're like brothers...only closer.

The chance of having conjoined twins is as much as 1 in 100,000; the chance of those twins surviving infancy is 25%. As of 2008, there are under 2,000 conjoined twins in the world, and about a dozen are living in the United States. You're more likely to get struck by lightning — twice! — than to meet a conjoined twin. But don't tell that to Hollywood — according to them, the chance of our heroes meeting two people who share one body is higher. Much higher.

Conjoined Twins combine Creepy Twins with Body Horror: Imagine being attached to another person, the same one person, for your entire life. Freaky stuff. As such, they are a staple of horror and any show that wants to unsettle its viewers. They are a must at carnival freak shows.

If the twins aren't just background characters, most other Twin Tropes will apply. Some cases may literally have been Separated at Birth. Multiple Head Case is a subtrope, about the tendency of beings with two heads to have opposite personalities.

For our purposes, people who aren't born twins but somehow still get fused together apply. With the exception of such artificial fusions, depictions of this trope which connect in places other than the body's axis (head, neck, or torso) are a Did Not Do the Research. Conjoined twins are also Always Identical Twins; those that aren't are likely running on Rule of Funny.

Conjoined Twins are a real phenomenon, and have been around pretty well forever. They became prominent in the 1800s, with the rise of carnival freak shows; the most famous pair was Chang and Eng Bunker, the original "Siamese twins," who were connected at the sternum. Most of the examples below are taken from The Other Wiki's page.

Examples of Conjoined Twins include:


  • Advertisements for the 2008 Howl-O-Scream in Tampa, Florida, featured the Raven Twins: twin sisters conjoined at the face who performed crude surgery to separate themselves. They date men in order to steal their face tissue and repair the damage done to the once-conjoined sides of their faces.

Anime and Manga

  • The creepy twins Sakon and Ukon from Naruto are conjoined... most of the time. Thanks to their special power they can meld their bodies into Multiple Head Case,turning Multi-Armed and Dangerous or separating for tag team attacks whenever needed.
  • One of the "sealed chapters" of Black Jack, "The Two Jans", had Black Jack operate on a little boy with two brains and two faces, but only one body.
    • Also, this is Pinoco's origin... sorta. She was supposed to be the twin sister of a young girl but her body was absorbed into her in the womb, thus becoming a sort-of parasitic twin - basically, a sentient tumor in her body. Black Jack removes the "tumor" but senses Pinoco's wish to live, thus he builds her a small body an adopts her after her "sister" rejects her.
  • Yudy and Yucy in the short story Henshin: Half God.
  • The sisters Raphaela and Luciella end up turning themselves into this in Claymore. Until they wake up.

  • There's a Nightwing villain(s?) that is two men who were fused together by some sort of toxic goo.
  • Castle Waiting: A pair of conjoined twins are billed as a two-headed girl at a circus (as the owner thinks that's more interesting than two girls joined at the waist).
  • In the Buffy the Vampire Slayer: Origin comic, Buffy fought a set of opposite sex conjoined twins who were running a casino-cum-vampire factory in Las Vegas. The brother was a vampire, and the sister was a good shot with her guns, making them a potent enemy. At the end, Buffy put holy water in the sprinkler system, then activating it, killing every vampire in the casino - including the brother. The human sister was left alive.
  • Charles Rodrigues had "The Aesop Brothers", a regular strip in the National Lampoon, starring siamese twins George and Alex (who curiously don't look alike), and their constant travails.

  • Big Fish stars twin sisters Ada and Arlene Tai as conjoined twins/Korean Glamorous Wartime Singers, Ping and Jing (pictured above). Hero Edward tells his son a Tall Tale about meeting them when he was on a mission during the war.

  • In The Stone Dance of the Chameleon, the masters believe Conjoined Twins, which they call "syblings" to be representative of their twin gods in some way. (The exact details elude me at the moment.) The twins share the same name ("Left-name" and "Right-name" are used to distinguish them if neccesary) and one of them is blinded at birth. Sometimes pregnant women are given a poison to induce the developing of Conjoined Twins.
  • Two of the Binewski siblings in Katherine Dunn's Geek Love are a set of beautiful conjoined twins named Electra and Iphigenia.
  • One (bad) Dungeons and Dragons novel featured conjoined twin goblins, attached at the hip, as leaders of a goblin tribe.

Since they lack hands, they couldn't untie it, and they were forced to grow up bound together, learning to co-ordinate their movements.

Cam: Oh, Mr. Nigel-Murray, I so missed your insights.


Angela: Guys, hello! IDing them is not going to be a problem. How many sets of conjoined twins can there be?

Cam: I did not expect him to know that.

Vincent: Well, all facts are useful. It's just the context that shifts.

  • The The X-Files episode "Humbug" features a circus performer whose under-developed conjoined twin separates from him and commits murder.

  • House of the Dead: Overkill features conjoined twins Nigel and Sebastian as the boss of the 'Carny' level.
  • Kingdom of Loathing has a Conjoined Zombie, which the game itself notes 1) Conjoined Twins are rare, 2) Conjoined Twins living to adulthood is even rarer, 3) the odds of them zombifying is even rarer than that, so this is probably the rarest thing in the world. As such, this is a Mini Boss and not a regular Random Encounter.
  • The Marcel-Moreso Brothers in Freaky Flyers, are not just conjoined twins (skinny twin growing out of pudgy twin's back), but they're also mimes. They toy with the idea of being surgically seperated (Which is shot down when the Narrator points out that they only have one pair of legs), and in the end, marry a woman with a split personality.
  • The carnival sideshow in Bully features a pair of conjoined twin girls.

  • The Oblongs features Biff Oblong and Chip Oblong as conjoined twin brothers with a particularly odd variant of sharing a leg and butt cheek (giving them a grand total of 3 legs and 3 butt cheeks)
    • To make things even more awkward than usual, Biff is gay and Chip is straight.
  • One episode of The Simpsons Treehouse of Horror featured Bart's Evil Twin, Hugo, who had been separated from Bart at birth and kept in the attic. Hugo, having gone insane after being locked up in the attic his entire life, plans sew the two of them together again.
    • Another Simpsons example: In the Monorail episode, Homer fashioned a makeshift anchor out of the M on the train. He tosses it outside, and it drags on the road. At the same time, Dr. Hibbert is advising a pair of conjoined twins about the "very tricky procedure" that might allow him to separate them — and then Homer goes by with the anchor, chopping them apart easily.
  • The Ren and Stimpy Show featured one episode where the two of them suffer a terrible bus accident and have to undergo a drastic plan to survive: being sewn together into one body. Hilarity Ensues.
  • One episode of The Powerpuff Girls had the three of them getting conjoined into one, all facing outward, with control of their limbs randomly shuffled. This was a plot by Mojo Jojo to ruin their ability to thwart him. This backfired when they discovered a super attack because of it and Mojo Jojo decided to seperate them than deal with even stronger PPG.
  • SpongeBob SquarePants features several examples of this.
    • In The SpongeBob SquarePants Movie, we meet a pair of conjoined fish in a bar.
    • SpongeBob and Squidward have also been conjoined repeatedly:
      • The particularly squicktastic episode "Squid Bob Tentacle Pants." Spongebob uses Sandy's teleportation device, then gets involuntarily teleported while Squidward has his arm in Spongebob's mouth. Squidward gets dragged through the teleportation device too, and when they arrive back at Sandy's Treedome, their bodies are joined together. Later, at the end of this episode, Spongebob, Squidward, and a bunch of other characters end up in one conjoined blob.
      • The episode "Can You Spare A Dime?" features a brief moment of horror in which Spongebob tells Squidward, "We're like brothers...only closer." (This, incidentally, is also one of the page quotes.) Cut to Spongebob and Squidward fused together by a band of flesh. (WARNING! Not for the faint of heart.) Fortunately, Negative Continuity makes things better after the next cut.
  • Zak and Wheezie from Dragon Tales.
  • Generator Rex has the breather episode Without A Paddle where Rex is convinced by Noah to join a Serious Business Ping-Pong tournament. The antagonists of that episode are their opponents from a rival school, an E.V.O that was a pair of twins, completely fused together but with two heads. The main problem was their overbearing father who pushed them (and juiced them) to win, which resulted in an Unstoppable Rage and Multiple arms
  • Mighty Mac from Thomas the Tank Engine, who is a double-ended Fairlie locomotive that has two faces on each side.
  • The Camp Lazlo episode "Valentine's Day" features a pair of pigs joined by an eyeball, with 3 eyes between. They claim it's because they're made of magic. They fly away and leave a beautiful rainbow. Yeah.
  • The school nurse on South Park has her dead conjoined twin still attached to her head.
  • An episode of I Am Weasel took place in a "correctional facility". Several of the inmates were outfitted with massive iron devices that were meant to correct certain deformities. One of them had a "Fred" device on his backside that when removed, revealed a full twin somehow forced under it. Pretty morbid.
  • In one Beavis and Butthead cartoon, our intrepid heroes wind up in the freak show of a travelling carnival as siamese chicken-head-biting geeks by unspecified means, after their inexpert attempts to chat up a female contortionist draws the ire of their Ape Man. Stitches are mentioned.

Real Life

  • As mentioned above, Chang and Eng Bunker, the original "Siamese twins". They actually were from Siam (actual Thailand), and were connected at the sternum. It's an oft-cited fact that they could easily have been separated if they were born today. These guys toured around America and helped shape the popular notion about what a conjoined twin is, before settling down, marrying a set of sisters, and becoming slave owners. Seriously. Their sons fought in the American Civil War. When Chang died in his sleep, Eng chose not to be separated from him, and followed him within three hours.
  • George Schappell (born Dori) is a country music singer; he is also a conjoined twin, attached to his sister, Lori, at the head.
  • Daisy and Violet Hilton who tried to make a living in films, and starred in the movie Freaks. Their life was one big tearjerker.
  • Abigail and Brittany Hensel look like a woman with two heads, but are actually conjoined twins. A segment on the Discovery Channel related the interesting level of cooperation required, as each girl controls the arm and leg on that side. They can legally drive, too (presumably, only automatic cars).
  • A conjoined frog (or frogs) was found near a children's day nursery in Britain. Unlike the other instances of this tropes, it wasn't just two conjoined beings but THREE - including three heads, three pairs of legs, and multiple other organs
  • There was a news article about Indonesian twins who had one body and two heads. They died shortly after, however.
  • A pair of twins in Brazil were similar to this and the Hensel twins. However, they died at age 16 when one had a fatal lung infection; like with Eng Bunker, the healthy twin refused separation, even once it was clear that that was effectively a decision to die with her sister.
