Always Identical Twins

Go To

Think of your favorite pair of fictional twins. Got them? Now, be honest: Are they identical twins?

If you answered "yes," there's a reason for that. Identical twins show up far more frequently in fiction than fraternal (non-identical) twins. If you don't believe us, take a Wiki Walk through Twin Tropes. We'll wait.

Welcome back! So why are fictional twins always identical? Well, for starters, identical twins are visually striking. They allow for comic plots, and they add symmetry and symbolism to a story. An Evil Twin is almost always an Identical Twin; how else could they impersonate the "good" twin? Fraternal twins, for all intents and purposes, are just regular siblings, and regular doesn't cut it in fictionland. Oh yes, and if it's an animated film or series, that makes it one less character for the artists to design and learn to draw.

This trope is so pervasive that it even manifests when the twins have different sexesHalf-Identical Twins shouldn't even be identical! Though it is certainly possible for fraternal twins to bear a Strong Family Resemblance (especially in early childhood), or for one twin to be transgender.

There are sometimes aversions, almost exclusively in live-action productions where twin actors or Double Vision are not available — though the work may instead have an actor Playing Their Own Twin. See also Alleged Lookalikes, when twins are said to be identical but are obviously not.

Identical twins are highly prone to Speaking In Unison or Finishing Each Other's Sentences. They often dress identically, especially if Limited Wardrobe is in effect; or, if not identically dressed, they may be just different enough for the purpose of distinguishing them—like their outfits will be two dresses or shirts with exactly the same cut, different only in being differently colored. There is also a pretty good chance their names will sound like a matched set just to drive home their relationship.

Keep in mind if the twin isn't established at the beginning, or only shows up after the other one died, prepare for rage from the fandom.

Chalk this up to The Law of Conservation of Detail — if they're not identical, there's usually no need to establish them as twins rather than just siblings.

If the twins are conjoined, they will most certainly be identical, as this is the case in Real Life, although fiction often allows for the possibility of non-identical, or even opposite sex, conjoined twins, generally for the Rule of Funny. If a family seems to bear a lot of twins, that is Hereditary Twinhood.

In reality, fraternal twins are significantly more common than identical twins — only 8% of twin births are identical, or 0.1% of all births. But how would it look if in fiction only one character in a thousand had an identical twin?

Note also that fraternal twins can be the same sex, although in fiction they are much more likely to be opposite sexes.

As this is a trope in aggregate, a single pair of identical twins appearing in an individual work isn't an example of the trope. Cases in which more than one pair of identical twins are present in a single work — essentially a microcosm of the trope — are examples. Cases where the trope is lampshaded, discussed in-universe, invoked, or suchlike are likewise valid.

Examples of Identical Twins:

  • In a series of commercials for State Farm insurance, Los Angeles Clippers point guard Chris Paul plays both himself and his (fictional) Separated at Birth twin Cliff, an insurance agent who was likewise born to assist.

    Anime & Manga 
  • Air Gear has identical octuplets, complete with identical outfits.
  • Armored Trooper VOTOMS features the Schmittel twins, who are (at first) only differentiated by their uniform color and voices. Even so, the animators were incredibly prone to slip up at remembering which one was which.
  • BanG Dream! has Sayo and Hina Hikawa. Physically, they can only be distinguished by hair length and style and fashion sense. Their personalities, however, are very different. Hina is a carefree genius who flits from interest to interest as it suits her, while Sayo is hardworking and serious, constantly striving to be successful and overcome the inferiority complex caused by spending her life in Hina's shadow.
  • Battle Angel Alita has Elf and Zwölf, AKA AR/GR-11 and AR/GR-12 respectively, android clones of Alita, who inexplicably behaves as if they were identical twins, and often fill the role of Alita's Annoying Younger Siblings.
  • Bleach: A major plot-point in the final arc centres around two brothers who are completely indistinguishable from each other. Their powers allow them to mimic the forms of others, an ability they discovered before birth when they learned to mimic each other. They were thus born visually identical. Loyd is killed when he mimics Kenpachi's sealed form. Kenpachi has to remove his eyepatch to grow stronger than the form of himself Loyd is using. However, Royd is mimicking Yhwach, so when the eyepatch-free Kenpachi confronts Royd, Royd instantly defeats him with his bare hands. He goes on to fight toe-to-toe with Yamamoto. Yamamoto does manage to kill him, but not before using all his power, including bankai, which allows the real Yhwach to kill Yamamoto.
  • Played with in Blood+: Chiropteran queens are always born in pairs, with one having red eyes and one having blue eyes, but otherwise the two are completely identical.
  • In the sequel to Brave10, Nanakuma is introduced by Kamanosuke intercepting him and demanding answers thinking he's his teammate Rokuro as they are identical in everything but the colour scheme of their Coordinated Clothes (white and indigo, and black, respectively). Seeing the two together shocks many of the other characters as historically one twin would often be killed at birth for superstitious reasons so the sight really is rare.
    Kamanosuke: You look exactly the same. It's disgusting!!
  • Kazuo and Masao Tachibana of Captain Tsubasa. The only way to tell them apart is by their jersey numbers. The two even take advantage of being Single-Minded Twins on the field, which makes them a very effective pair with each other.
  • Riku and Risa Harada from D.N.Angel are identical twins, who can only be told apart by hair length (and personality). On occasion, they used this fact to their advantage. In the anime Riku's hair is a lighter shade of brown, to further differentiate them.
  • Played with in Eyeshield 21. Agon and Unsui dress and act very different from each other and whether they were fraternal or identical was left somewhat ambiguous for most of the series (although covers made it clear they are identicals). However after Agon gets a haircut, everyone is amazed to see he and his brother are very much identical.
  • Futakoi is all about this trope. There are six pairs of identical twins in the same series.
  • Takuma and Kazuma from Gakuen Babysitters look exactly alike, though they are easy to tell apart once one looks at their faces and judge their temperament; Takuma is perpetually cheerful and Kazuma is perpetually tearful.
  • GoLion had Takashi and Ryou Shirogane, the latter of which served as a Backup Twin after Takashi died (and died himself a little while after).
  • The first and only pair of twins Haikyuu!! introduces are identical, although they part and dye their hair differently and have distinct personalities so it's easy to tell them apart. The series introduces Inarizaki's talented setter Atsumu Miya first, and it's only about 30 chapters later that the audience (and Karasuno) finds out he has a twin on his team, the wing spiker Osamu. It's said that even if you take down Atsumu, "his twin Osamu will be right there to pick up the slack".
  • In High School Star Musical, Nayuki's younger sisters, Tsumugi and Yuki, look identical, though they are Polar Opposite Twins in personality. Tsubasa and Itsuki are fraternal twins, though.
  • In Makura no Danshi Yonaga and Yayoi Sagiri are identical twins who make flower arrangements. To differentiate them, Yonaga has his hair swept to the left and Yayoi has his hair swept to the right.
  • Played with in Maomarimo: Mao and Ako remain fraternal twins even after Mao's Gender Bender, but the issue is raised by a background character who wonders why this trope wasn't invoked when Mao became a girl. Technically, Mao isn't Ako's twin (though it's plot-relevant that they were born on the same day) but Mao doesn't know he was adopted (and Ako is concealing it for reasons of her own) so their classmate gets a lecture on the difference between fraternal and identical twins instead.
  • Miracle Girls:
    • Toni and Mika are identical twins with psychic powers. Toni has Boyish Short Hair and wears more tomboyish clothes than her sister, so the fact they're identical is slightly less apparent than other examples.
    • Toni and Mika's mother and their aunt are identical twins.
    • Partway through the manga, the plot involves a European country where the crown is ruled by identical twin queens and has been for centuries. One of the twins however is missing. Her sister is looking for her in order to kill her so that she can be the sole ruler.
  • Naruto features two sets of identical twins (Hiashi and Hizashi and Sakon and Ukon). Coupled with Shadow-Clones and Generation Xerox, Masashi Kishimoto seems fond of twins... then again he himself is one, and his younger twin Seishi is also a mangaka.
  • Osomatsu-kun is about identical sextuplets. Yes, six brothers who look exactly alike. The running gag in the early episodes was that other characters couldn't tell which is which. The revival series Osomatsu-san makes them easier to tell apart by giving each of them several distinguishing points along with color-coded outfits.
  • Ouran High School Host Club has the Hitachiin twins, who are so alike that no one had ever been able to tell them apart until they met Haruhi (made worse by the fact that they were dressed identically as children by their parents and staff). Of course they use that similarity for their own amusement, but it's also implied that it's also the reason they can be a bit bitter and cynical; Haruhi's ability to tell them apart, unique among everyone except their immediate family, is one reason that they consider her one of their favorite people.
  • Pokémon: The Series has a couple cases:
    • During the Advance Generation series, Ash and May meet a pair of identical twins named Forrest and Forrester, and the only way to tell them apart is through the colors of their shirts, and Forrester having a mole under his right eye.
    • Lana's younger sisters, Harper and Sarah, look like identical mini-clones of her. All of them clearly take after their mom.
  • The Quintessential Quintuplets centers around identical quintuplet sisters, which in Real Life is almost unheard of aside from the famous Dionne quintuplets.
  • Saint Seiya:
    • The known Gemini saints always seem to be fated to be identical twins, most notably with Saga and Kanon in the original series, as well as Aspros and Deuteros in The Lost Canvas, and Paradox and Integra in Omega. There also seems to be a curse that one of the twins is good while the other is evil, or that one of them will inevitably develop an evil Split Personality at some point.
    • The anime-only Asgard saga also had Mizar Zeta Syd and Alchor Zeta Bud, who were Separated at Birth due to a superstition in Asgard that when twins are born, one is destined to become evil.
  • In Saki, Kana has three younger sisters- Shirona, Nazuna and Hina- who appear to be identical triplets. She often has to care for them, and while they don't show up much in the series proper, they often appear in Saki Biyori.
  • Yoh, the protagonist of Shaman King, is revealed to be the identical twin of Hao, the Big Bad of the series.
  • One episode of Sherlock Hound has Sherlock and Watson dealing with a pair of twins, one is a navy commander and the other is an insane treasure hunter.
  • Tomo from Shonen Note: Boy Soprano has younger identical twin sisters.
  • Miraitchi and Clulutchi from Tamagotchi have an impressive amount of Identical Twin ID Tags to give them more distinct appearances, but they still have the same basic white-skinned humanoid alien design at their core. In-universe, they keep having to explain to others that they're "not alike at all."
  • Tsubasa -RESERVoir CHRoNiCLE- has Fai and Yuui , the "twins of misfortune" who are practically the same child made twice.
    • Horitsuba Gakuen has the above mentioned twins as well as Syaoran and Syaoran. In the actual series they're clones but the Alternate Universe extra portrays them as identical twins. To make it even weirder in the main series Syaoran technically does have a twin — Watanuki, but the two of them are not identical at all.
  • From Virgin Ripper, there's Kotori and Kotoha, completed with Coordinated Clothes and Theme Twin Naming.
  • You and Me features identical twins Yuta and Yuki Asaba as two of the main characters. They're both stoic, but Yuki is Brilliant, but Lazy and an otaku while Yuta is sarcastic and mature. The twins also have slightly different hairstyles.
  • Yuri!!! on Ice has Axel, Lutz and Loop Nishigori, who are identical triplets. They can be told apart by their hairstyles and color-coded outfits.

    Comic Books 
  • De Argonautjes has Castor and Pollux, two identical Pintsized Powerhouses.
  • Arawn: The four sons of Siahm are two sets of identical twins spawned from a different father. Math and Kern were the sons of her husband Dag, Arawn and Engus were the sons of her rapist Bran. Each one looks identical both to their twin and their sire.
  • In one of the comics based on the DC Animated Universe, specifically on Batman Beyond, Terry is surprised to find his former "Catwoman" has turned back to crime after swearing to go straight... especially when she doesn't have injuries she sustained during her latest heist. Turns out it's not her; both her parents had identical twins, who married each other, and their daughter came out looking a lot like her.
  • Batman: Black and White:
    • "A Matter of Trust": Bruce has to mind a pair of rambunctious twins. For added confusion, they're identical twins and he has trouble at first telling which one is which.
    • "Fortunes": A detective is hired to investigate the disappearance of a woman's sister. The sisters are identical twins, which turns out to be a plot point: the detective's client is the disappeared woman, who has murdered her sister and is now impersonating her.
  • The Fix-it Twins who appeared in The Beano in the late 70s .
  • Girl's comics had quite a few examples, such as "Last Chance for Laura" from Bunty or "The Two-In-One Taylors" from Mandy. Being identical would enable them to perform a Twin Switch every now and then.
  • Jommeke: Annemieke and Rozemieke, who are young twin girls who are basically the same characters and also look the same.
  • Mandrake the Magician and his Evil Twin Derek.
  • La Ribambelle: Atchi and Atcha are two young Japanese twin brothers, who often talk and move in unison.
  • Richie Rich: Upon learning of a poor country where kids can legally get married, Mayda Munny lures Richie there under the pretense of making a movie to help them. Her plan fails because the Justice of Peace, having a real marriage to officiate when Mayda had her "fake" one to Richie, sent his twin brother to perform his role in the "movie".
  • Robin: Two of Sebastian Ives' many cousins are a pair of identical twin girls. Since they're both jovial with similar personalities, and their parents give them matching outfits and keep their hair cut the same way, the easiest way to tell them apart is seeing which one tries to keep her clothes clean and tidy and which one has ribbons untied and doesn't seem to care much how nice her clothes look.
  • Wendy and Goldie, twin prostitutes from Frank Miller's Sin City. According to Marv, they even smell identical. Granted, he is insane and at one point, even mistakes one twin for the other despite knowing full well she was dead.
  • Suske en Wiske: In "De Schat van Beersel" an identical looking triplet plays an important role.
  • Tintin:
    • A strange example are Thompson and Thomson who, apart from their moustaches, look exactly like twins. They dress, act and move the same and often finish each others' sentences. They also appear to live in the same house and even in the same bed! Still the linguistic difference in the spelling of their name suggest they are not related to each other at all. Furthermore, in the original French, they were known as Dupont & Dupond, which are even pronounced identically — this was kept up at least to some extent in most translations, including English, where they are known as Thompson and Thomson.
    • A better example are Alfred and Nester Halambiek in King Ottocar's Sceptre, who are a good and evil twin, looking exactly alike, save for the fact that the good one smokes and is far-sighted.
  • Wonder Woman:
    • Wonder Woman: The villain Hynota has an identical twin sister named Serva, and the two pull off twin switches as part of their magic show.
    • Wonder Woman (Rebirth): It's obviously a choice considering their shapeshifting capabilities but Deimos and Phobos take care to appear quite identical in their various forms. They cared less about this pre-Flashpoint but seem to enjoy playing up the Creepy Twins angle, they are fear gods after all.
    • The Legend of Wonder Woman (2016): Two of the Holiday Girls are the identical twin sisters Milly and Tilly Heyday.

    Fairy Tales 
  • In "The Two Brothers", collected by The Brothers Grimm, a poor man has two children, "who were twin brothers and as like each other as two drops of water." It takes nearly the entire story for this to become plot relevant, but it eventually does when one brother goes missing and the other is mistaken for him when he comes to find out what happened to him.

    Fan Works 
  • Kirstin and Nicole Porter from the Ranma ˝ Fan Fic Boy Scouts ˝ are identical twins.

  • Codex Equus:
    • Bossa Nova Heartstrings and his younger brother, Blue Suede Heartstrings, are identical twins who have since Ascended to godhood, and because of this, they look exactly the same except for a few differences - Bossa Nova has a dark red mane and tail made of musical energy, dark red wing gradients on his wings, and a skull-shaped guitar Cutie Mark surrounded by a halo of music notes and flanked by black wings. Meanwhile, Blue has a dark blue mane and tail made of musical energy, dark blue wing gradients on his wings, and a red, heart-shaped electric guitar Cutie Mark surrounded by a halo of music notes and flanked by white wings. The fact that they're identical twins initially caused Temnobog to assume that they were magically separated in the womb by their own father until they confirmed that no, they were just born that way.
    • Alicorn Princes Star Cut and Alpine Butterfly are identical twin brothers. The fact that they are identical twins caused Temnobog to assume that they were split inside the womb by their father in his quest to make his unborn son perfect and completely flawless. They confirmed that while they did split inside the womb, it wasn't because of their father's meddling, as they were born naturally.

    • In the Dark World, Apple Pie had an identical twin named Poison Apple, though they had different Cutie Marks. Unfortunately, Poison Apple was killed by Fluttercruel. She comes Back from the Dead in the end though.
  • Ivor and Ivan are identical twin members of the Blades of Hessarian in the Twice Upon an Age series. (This is based on the fact that there are two identical-looking young men in the Blades' camp in the game, should the Herald of Andraste duel and defeat the Blades' corrupt leader; one of these identical figures serves as the group's mouthpiece, explaining to the Herald that he or she is now their leader. The game never identifies the two men as identical twins, but it seems probable.)
  • Though their canon counterparts play the trope very straight, the GenderFlipped Weasley twins very much avert this in the Harry Potter AU fanfic, Holly Potter and the Witching World. They're fraternal twins, who while they resemble each other greatly, are not identical. For one thing, Fred is taller than George — for another, they were assigned different genders at birth, with Fred being a transgender girl while George is a cisgender girl.

  • This was the main driving force behind the plot of Cronenberg's Dead Ringers.
  • Exaggerated in Godzilla: King of the Monsters (2019). The Monarch scientist, Ilene Chen, has an identical twin who also works for Monarch, we see in a photo their mother and her mother were also part of identical twins (all of whom also worked at Monarch), and it's also stated in supplementary material that Ilene has identical twin daughters. This is because Ilene and her sister (and by extension, their entire family line) are this universe's version of the Shobijin, twin priestesses who have a telepathic link with Mothra.
  • There are two pairs of twins in A Haunting at Silver Falls, and both are identical.

  • Jack & Diane: Diane and Karen, her twin, are completely identical. They even sound alike, so Jack mistook Karen as Diane on the phone. Both dress very differently though, and have different hair color.
  • In Jack and Jill, Adam Sandler plays both brother and sister in a set of twins. However, identical twins always form in the same ovum and are always the same sex, whereas twins of different sexes form separately. It is logical to argue that they look the same because they're related, but they're identical in the film because Sandler plays both.
  • The old kung-fu film, King Eagle has the daughters of the Mongol chieftain, a pair of twin sisters (played by the same actress). The elder sister is a Dark Action Girl serving the main villain in secret, while the younger is in love with the film's hero.

  • In the Anne of Green Gables series, this trope is often discussed in reference to Anne and Gilbert's middle children. Nan and Di are fraternal twin girls, emphasized as being Polar Opposite Twins in both looks and personality. It's frequently commented on as odd, since most believe this trope to be true. Especially the local children. A particularly mean-spirited little girl invokes this trope when she convinces Nan that she was really Switched at Birth with a hard-drinking fishmonger's daughter, who is red-haired like Di and their mother, Anne. Nan is distraught, but decides to do the honorable thing and try to switch back with this other girl. Nan finds out she's been had, however, when the girl's stepmother reveals there's nearly a year between them and there's no way they could have been switched.
  • The Baby-Sitters Club has a few sets of twins, almost always identical.

In the films, this trope was both confirmed by the Weasley brothers (played by real life identical twins James and Oliver Phelps) while averted in the fraternal twin Patil sisters, who were played by unrelated (though similar looking) actresses.

Private eye Mike Hammer is hired by a well-respected politician who has an evil twin brother who's committed a murder in an attempt to destroy his brother's reputation. However, during the investigation Mike discovers that the brothers don't look alike because they're fraternal twins, so the politician is the murderer after all.
  • Sascha and Boris Roznine in Pegasus in Flight.
  • "The twins" (No Names Given) in Peter Pan, "who cannot be described because we should be sure to be describing the wrong one." Note that Peter doesn't really know what "twins" are, and the animated series Peter Pan & the Pirates subverted this trope by making the twins different colors and heights, the implication being that they're merely good buddies who were labelled "twins" because they are always together and finish each other's sentences.
  • Reuhurinteen ala-aste: Sipuli and Tupuli look the exact same. This causes problems for Kippari, who has a crush on one of them, but isn't sure which.

  • Split Heirs: All of the triplets are identical to each other (at least over the waist, as one is female while the others are male), so much that that each is even mistaken for the others repeatedly.
  • Enid Blyton's St Clare's series has twins Pat and Isabel O'Sullivan. Both girls look near-identical, and were able to pull a Twin Switch during their first year at school, but after some time, the other teachers and students eventually learn to tell them apart.
  • Nypre and Deren, the first two characters introduced in the Stories of Nypre are identical twins, though its never been said if they are so identical as to be indistinguishable from one another.
  • Sweet Valley High:
    • Protagonists Jessica and Elizabeth Wakefield. As repeated in every book, they're only distinguishable by a mole Elizabeth has on her shoulder and Jessica doesn't. Also, Elizabeth wears a watch and Jessica doesn't, and Elizabeth has a more modest clothing style as opposed to Jessica's more sexy and fashionable clothes. They frequently even fool their parents by posing as each other.
    • The identical evil twins Nora and Margo, who other than hair color are so like Elizabeth and Jessica that they're even able to fool the other twins' parents.
  • Tolkien's Legendarium:
    • Elladan and Elrohir of The Lord of the Rings are not outwardly stated as being twins or even identical, but because their birth year is the same and elves wait at least ten years between children, they are assumed to be twins. They are also said to be "So much alike were they, the sons of Elrond, that few could tell them apart: dark-haired, grey-eyed, and their faces elven-fair, clad alike in bright mail beneath cloaks of silver-grey."
    • Tolkien also has Amrod and Amras, the youngest sons of Feanor from The Silmarillion: "twin brothers, alike in mood and face."
    • Elrond himself was a twin; however, the text doesn't say they were identical, and after Elros chose to become mortal and age they became less so.
  • The main characters of the T*Witches series are identical twin girls.
  • Two Little Girls in Blue:
    • Kathy and Kelly are identical twins. They look very similar and have similar interests, although there are differences in their personalities: Kelly is more outspoken and defiant, while Kathy is quieter and more timid. Kathy also gets sick more easily, quickly developing a bad cold within days of being kidnapped. It's mentioned they were technically conjoined twins as well; they were born with a thin membrane attaching their thumbs to each other, which was removed, and they still have a tendency to hold hands.
    • Norman and Theresa had identical twin sons who unfortunately died at birth, with Steve's twins reminding Norman of his boys. It's mentioned that when she disappeared Theresa was expecting twins again, though it's not known if they were identical or fraternal.

    Live-Action TV 
  • All My Children had Adam and Stuart Chandler, both played by the late David Canary.
  • Another World: Marley and Vicky Hudson.
    • Eventually, this was averted in a strange way. After several recasts, the original Marley actress returned, but Vicky was not recast. The explanation was Marley had an accident that resulted in Magic Plastic Surgery that somehow also left he several inches taller than she'd been before the accident.
  • The Barrier: Julia and Sara look similar enough to be played by the same actress, and for Julia to be able to fool plenty of people while pretending to be the recently-deceased Sara.
  • Big Sky: Rick Legarski turns out to have a twin brother in Season 2 named Wolf, who is his spitting image (played by the same actor). They initially have different hairstyles, but Wolf then changes hair his to match Rick's at his wife's insistence as a better way of getting to Ronald.
  • The Bold and the Beautiful had a rather interesting example. Twins Stephanie and Phoebe Forrester were identical twins until they graduated high school. From that point on they've been fraternal.
  • Played with in Dead to Me, in which Ben and Judy are insistent that the twins aren't identical, even though they're played by the same actor, and as far as Jen can see they might as well be.
  • The Doctor in the House franchise features two examples, achieved via Acting for Two (or Three).
    • In "Brotherly Hate" from Doctor in Charge, the humourless crawler Lawrence Bingham is revealed to be one of a set of identical triplets, and always resented being overshadowed by his cooler brothers Lionel and Leonard.
    • Professor of Surgery Sir Geoffrey Loftus is revealed to have an identical twin brother, Captain Norman Loftus, in the first episode of Doctor at Sea, so that when Drs. Waring and Stuart-Clark sign on as ship's surgeons, they will still be serving under a Loftus (and in contrast to the Bingham triplets, the Loftus brothers are very similar in personality).
  • Friends: Phoebe and Ursula, which allows various friends and colleagues to mistake them for each other in Ursula's first episode. Amusingly, when they think Phoebe is doing porn movies, Joey refuses to watch the video. But when they discover it's actually Ursula, he has no problem. The twin thing was a Throw It In moment, as Lisa Kudrow initially played Ursula on Mad About You, and then was cast in Friends. In order to 'explain' why Lisa was on two shows at once, the network made Phoebe and Ursula twin sisters.
  • Faking It: Zig-Zagging Trope. Petra and Pieter, the first twins who appear, are an obvious subversion since they're female and male. Later though Lauren has a pair of female twins as her latest "New Lisbeths".
  • Guiding Light: Lujack Luvonaczek and Nick Spaulding.
  • Himmelsdalen: Helena and Siri look exactly alike. It's necessary to cause the switch that sparks the plot.
  • The Indian Detective: Mumbai's "Terror Twins", Gopal and Amal Chandekar. They look identical, though their respective accents reflect where they stay most often (the former is based in Mumbai, the latter in Toronto).
  • Interview with the Vampire (2022): Grace's two daughters and the MacPhail brothers are identical twins, and both pairs of siblings wear matching outfits to further accentuate their sameness.
  • All pairs of twins in Jane the Virgin are identical: the Zazos, Valeria and Victoria, Petra and Anezka, and Petra's own daughters Anna and Ellie. This allows the show to liberally use the oft-lampshaded Evil Twin and Twin Switch tropes.
  • L.A.'s Finest: Syd meets twin brothers while in a bar (whom she hits on for sex later), while both are completely identical, even with the same dress and hair style.
  • A League of Their Own (2022): Jess, Lupe and Carson run into unnamed identical twin sisters in the gay bar. The pair are played by real identical twin sisters Kora and Ava Duvall.
  • The title characters of Liv and Maddie are, by contrast, played by one actress, Dove Cameron.
  • While the title quads in Nicky, Ricky, Dicky, and Dawn are an aversion, the Kramden quads are two sets of identical twins.
  • Once Upon a Time reveals that the real Prince Charming is actually dead, and he's being impersonated by his identical twin brother (who was raised as a peasant).
  • Subverted in Our Miss Brooks, when Connie Brooks impersonates her nonexistent twin sister Bonnie so she can moonlight at a diner.
  • Orphan Black: It turns out that of the numerous clones, two (Sarah and Helena) are actually twins. Their birth mother was implanted with an embryo like all the others, but it split inside her. In this case it's justified that they're identical; fraternal twins are when two eggs are fertilized at the same time, which of course was impossible in this case. Identicals result from a split ovum, as stated here.
  • Outrageous Fortune: Van and Jethro West, with wildly contrasting personalities.
  • Peter Punk: The Pop twins Andy and Michael.
  • Power Rangers Zeo has the character Trey of Triforia (also known as the original Gold Ranger). He is an alien whose race are composed of three separate entities that are normally unified as one, but due to being injured in battle cannot keep his singular form and has to appoint a successor to his Gold Ranger powers while he recovers. The Treys are played by identical triplets Ted, Tom and Tim DiFilippo. This series also introduces Tommy's twin brother David.
  • Nearly every set of twins in The Pretender, from regular character Sydney and his brother Jacob down to the briefest one-off appearance. Particularly notable was the episode where Sydney visits a Twins Convention, which is populated entirely by identical twins sticking together and wearing coordinated outfits.
  • Parodied in Scrubs with a set of identical twin brothers who dress the same, and are even both gay. They get offended when Elliot can't tell them apart, assuming it's because they're black.
  • Tia Landry and Tamera Campbell on Sister, Sister are long-lost identical twins, played by real life twins Tia and Tamera Mowry. For a while producers even had one twin wear a fake mole to match the other, but they eventually abandoned this. The fifth season's main goal was to distinguish the sisters' personalities even more.
  • Emily and Katie Fitch from Skins are identical twins, played by real life twins Kathryn and Megan Prescott respectively.
  • The Stanley Dynamic plays with this trope. Larry and Luke are described as identical twins, but one of the brothers is an animated character.
  • The Star Trek: Deep Space Nine episode "Vortex" features a pair of identical Miradorn twins, both played by Randy Oglesby, who also happen to be Single-Minded Twins. When one is killed, the other one is left seriously unbalanced.
  • Star Trek: Voyager has the occasionally-mentioned Delaney sisters, Jenny and Megan, who finally appear in "[[Star Trek: Voyager: S5E9: "Thirty Days" Thirty Days]". They are pretty much identical, though Harry Kim points out a subtle difference (one has a dimple on her cheek that the other one doesn't) that Tom Paris doesn't notice.
  • Star Trek: Picard: Dahj and Soji are completely identical, and both are played by Isa Briones. Justified as they're also biological androids, and thus created that way artificially.
  • Zack and Cody on The Suite Life of Zack & Cody, also played by real life twins. Puberty made them not so identical. A set of British twin girls were recurring characters too. Naturally they go on double dates with Zack and Cody.
  • Teen Wolf has Aidan and Eathan, who are not so much Single-Minded Twins as single-giant-wolfed twins. Their personalities are different, though, particularly when it comes to their sexualities.
  • Thunderstone has Sundance and Sutch, both played by Damien Fotiou.
  • Two Sentence Horror Stories: In "Crush" Jane and Mabel are identical twin sisters. Jane complains of having the same face, since people would mistake her often for Mabel, as the famous one who once was an actress.
  • Utopia (US): Numerous twins appear in the series working for Christie, all identical. It's indicated Christie finds them useful as control groups, given they're genetically identical.
  • Whitechapel: The new "Kray" twins. As they're based on the real ones, who were identical, this is justified.

  • L and R Nomura of Marginal #4. They have different hair colors - yellow and green, as part of their unit's color motifs, but besides that they're almost completely identical. It isn't stated whether or not both of them have their natural color.

  • Castor and Pollux, the twins in Classical Mythology who became the constellation Gemini, are usually portrayed as looking identical. However, the standard version of the story says they were actually half-brothers, because Pollux was a demigod, the son of Zeus and Leda, and Castor was the mortal son of Leda and her husband. (They were also actually quadruplets with their sisters Helen of Troy [demigodess] and Cytemnestra [mortal], with the four siblings being hatched from two eggs [because Zeus took the form of a swan]. The myths vary as to how they were distributed, but neither version exactly works — if the boys are in one egg and the girls in the other, they must be full siblings, but if the mortals are in one and the demigods in the other, they're Half-Identical Twins.)

  • Dice Funk: It turns out that Emma and Tamzin are identical twins.

    Tabletop Games 
  • The Ravenloft setting has Laurie and Gennifer Weathermay-Foxgrove, identical twin monster-hunting heiresses, as well as Jacqueline and Louise Renier, identical wererat littermates.

  • The mix-up in The Comedy of Errors is caused by two sets of identical twins confusing themselves for each other.

    Video Games 
  • In the fourth Detectives United game, the Big Bad is Mortimer Brown, Agent Dorian Brown's twin brother. This is an unusual one, as it's not clear whether the twins are identical or fraternal. However, because they are both invisible men who dress identically, and even sound exactly alike (both are voiced by Chris McCann), they are for all intents and purposes identical. Naturally, this leads to a case of Spot the Imposter for the heroes.
  • Devil May Cry:
  • The Elder Scrolls V: Skyrim: In Rorikstead, the Dragonborn can meet the unlikable Lemkil and his twin daughters, Britte and Sissel. This is a humorous example, however - the girls have to be identical twins, because there are only two models (one boy and one girl) for all the children in Skyrim.
  • Mio and May from Fatal Frame II are only visually differentiable by their hair parts and outfits. This also applies to all other twin pairs in the game.
  • Twin brothers Edgar and Sabin Figaro of Final Fantasy VI are biologically identical, but sport different hairstyles and builds (Edgar has long hair and an average build, Sabin has a shorter and messier version of his brother's hairstyle and is taller and bulkier), differences that allow anyone to tell them apart. They used to look more alike when younger - with Sabin being actually smaller and sickly - but 10 years apart in two different environments influenced their growth, causing Sabin to become taller and more muscular than his brother (which caused him to be mistaken for a bear by Terra in the game and by Mog in Dissidia Opera Omnia)
  • In the Grim Tales series of hidden object games from Elephant Games, Anna Gray and her sister Luisa are identical twins. At one point, they learn that years before they were born, they had a pair of half-sisters who were also identical twins.
  • The Idolmaster:
    • Ami and Mami Futami of the original series.
    • Yusuke and Kyousuke Aoi of SideM, though they make it easier out of costume by Kyousuke's need to wear glasses.
    • Amana and Tenka Oosaki of Shiny Colors.
  • Enter and Return in LEGO Island
  • The Legend of Zelda:
    • In the Oracle games, Koume and Kotake are identical apart from the gems on their foreheads being different colours.
    • The Legend of Zelda: A Link to the Past has identical twin lumberjacks.
    • Due to the model reuse in Majora's Mask, there's at least three sets of twins identical in everything but clothing colour.
  • Lucas and Claus from Mother 3. The game's narrative (as well as its inspiration) make it excessively clear that the two are meant to be completely identical, though they are curiously depicted with different hair colors—Claus ginger and Lucas blonde. Ironically enough, there's a perfectly good explanation for this if one considers them to be human chimeras—in the genetic sense. The game makes it a point to mention numerous times how indistinguishable the twins look regardless of this art direction.
  • My Cafe features two pairs of twin siblings, Ann & Chloe and Koffsky & Edward. Both pairs are identical.
  • In the Nancy Drew game Warnings at Waverly Academy, there are the identical twins Rachel and Kim Hubbard. However, Rachel sneaked Kim in without anybody knowing it and before the truth comes out, sometimes you speak to Rachel and other times to Kim. The only way to tell Rachel and Kim apart is that Kim always tucks a stray lock of hair behind her ear; Rachel doesn't.
  • Caroline and Justine in Persona 5: the only differences in their appearance are different hairstyles and which eye they wear their eye patches on. However, this is actually a subversion: the reason they look alike is because they are literally two halves of the same person.
  • One of the most recurring trainer classes in Pokémon is the "Twin" class, which features identical twin girls somewhere between 4 and 7.
  • Kiki and Viola DeWynter of Saints Row: The Third, who differ almost entirely on parts of their models being mirrored and the color of their sunglasses (Kiki's are pink while Viola's are white). In the game's backstory, after Zimos slept with one of them, they imprisoned him to take over his business - not because he slept with one of them, but because he didn't (and still doesn't) know which of them he slept with.
  • Redmond and Blutarch from Team Fortress 2, you can only tell them apart because Redmond wears a red suit and Blutarch wears a blue suit.
  • Way of the Samurai 3: The series had already established by this point that there's a lineage of identical blacksmiths named Dojima, and this game takes things even further by having the current incarnation of Dojima being twins, both of them even having the same name.
  • What Remains of Edith Finch has the twins Sam and Calvin. Having vastly different personalities and wearing different clothes it may not be immediately apparent that they are identical and they are not explicitly stated as such, but if you look close enough it can be deduced that they are in fact identical twins.
  • Xenoblade Chronicles 3: Number Seven (Segiri) and Number Thirteen are clearly identical twins. The interesting part is that due to everyone being born from Uterine Replicators, no one knows what siblings are, much less twins. Segiri mentions that no one in the colony ever understood why they looked identical, or their strange connection. Funnily enough, the Uterine Replicators also justify the "always" part of this trope; for all we know we see plenty of other twins and siblings, but no one notices because they don't look identical.

    Visual Novels 
  • Ace Attorney:
    • Trials and Tribulations has the twins Dahlia and Iris Hawthorne, whose only physical difference is Dahlia having dyed her hair red. They never share scenes, but Dahlia impersonates Iris in the final case. And Iris impersonated Dahlia during Phoenix's relationship with the latte in college.
    • Spirit of Justice does it again with Bonny and Betty de Famme. In this case, it's justified in that the two are stage magicians, a field where identical twins are commonly hired for the specific purpose of one twin being able to impersonate the other.
  • One of the biggest reveals regarding Super High-School Level Bodyguard Isshiki Madarai in Danganronpa Zero is that he's one of a group of identical octuplets, all of whom share the title of Super High-School Level Multiple Birth Siblings. Not only do they all look identical, they can synchronize flawlessly, which they utilize to make it seem like they're one immortal man.
  • Shion Sonozaki from Higurashi: When They Cry uses this to her advantage, as she assumes her sister Mion's identity to manipulate as well as to cover up murder in the Watanagashi and Meakashi arcs. Her sister did the opposite, more jokingly, in the same arcs. The two twins also switched identities when they were younger. Shion is technically the older twin, Mion, but has to live permanently as Shion since her little sister was branded with a tattoo instead of her.

    Web Comics 
  • Alice and the Nightmare: Deetran and Dumquil Vena are almost literally mirror reflections of each other, save for their scars.
  • El Goonish Shive plays with this: Susan and Diane are heavily implied to be twins, although they have different hair colors and heights. However, one of them had recently gone through an intense magical awakening, which resulted in her getting a growth spurt and the change of her natural hair color. Originally both girls were blonde, and one of them dyed her hair. But they're not twins at all; while they were born within an hour of each other, it was to different parents. That said, Diane's father is Susan's ancestor — he is an elf, for whom Immortality Begins at Twenty — so their similar appearances aren't completely a coincidence. Susan even notes that Raven (Diane's father) looks just like her own father.
  • Girl Genius: Sun Mingmei and Sun Daiyu are identical since they were originally intended to be the same person before an overlooked error was pointed out to the authors and Kaja loved the idea of resolving it by making them twins.
  • Discussed in Jupiter-Men. Quintin's hair is shorter and thicker than his sister Jackie's much curlier and more voluminous hair. Their eyes are slightly different shades of brown and Quintin's hair is dyed light green at the ends. They don't dress alike either, with Quintin wearing a simple hoodie and shorts while Jackie wears denim over a shoulderless blouse and short shorts. Rick is surprised to learn that Quintin is Jackie's twin, as they're fraternal twins who don't look identical, initially assuming that they're simply friends.
    Jackie: Hmm... have I never mentioned my twin brother?
    Rick: Twins...? But you guys don't look the same.
    [Beat Panel as Rick looks between the two of them]
    Jackie: Jeez! I sure hope not!
    Quintin: Hey!
  • Legostar Galactica: Bob and Rob Smith. Subverted in that Rob is an evil clone of Bob created by the Remulans as part of an abandoned infiltration plot.
  • Magical 12th Graders: Sort of. Yeorum and Gyeowul are not twins, but they look nearly identical despite being a year apart. The "Gyeowul" running around is actually an older version of Yeorum, and not even Yeorum notices.
  • The Order of the Stick: Elan and his Evil Twin Nale.
  • Precocious has the Et Twins, whose names are unknown. They're usually referred to as "Thing 1 and Thing 2", except neither of them actually have a designated number, so those nicknames get swapped based on what shirts they decided to wear. Sometimes they even wear the same number simultaneously.
  • Sailor Sun Bay(Brad) and Heather after Bay's Gender Bender. We don't know if they were Half-Identical Twins prior to the Gender Bender because Brad has never been depicted in the comic. It's even a plot point because in the backstory Bay & Heather found each other (they'd been Separated at Birth) after Heather was hired to play Bay's role in a touring production of Sailor Sun based on her identical appearance.

    Web Original 
  • AFK: Brendon made an alt character of his who's the former's twin brother.
  • Anon: Tucker and Hunter. Even Tucker's girlfriend struggled to tell them apart at first.
  • The Twins (2022): Apart from their different clothing choices and hairstyles, Lake and Lucas are identical in physical appearance. This allows Lake to seamlessly take Lucas's place when the latter dies.

    Western Animation 
  • Arthur has D.W.'s classmates Timmy and Tommy Tibble.
  • Avatar: The Last Airbender:
    • Lo and Li, Azula's ancient caretakers. Not even Azula can tell them apart.
    • ATLA also had a set of twins in the episode "The Fortuneteller," who were identical except one was an Earthbender and one wasn't.
  • The DeeDees (real names Delia & Deidre Dennis) from Batman Beyond: Return of the Joker.

  • Classic Disneyshorts: In Casey Bats Again, two of Casey's nine daughters are twins who look identical to each other.
  • Camp Lazlo has two sets of identical twins: the dung beetles Chip and Skip and the loons Dave and Ping-Pong. There are some superficial differences that tell them apart, but they basically look like clones of each other. There's also a set of of identical quadruplets, the Lemming brothers. Unlike the Dungs and the loons, there are no differences that separate the lemmings.
  • Teddy and Leo Platypus on Daniel Tiger's Neighborhood are this. Daniel at first is confused about there being two Teddys and Mom Platypus explains about them being twins. Teddy wears an orange shirt bordering towards pink, Leo wears a turquoise shirt bordering towards light purple.
  • The Davincibles has a villainous example. The Tenors Aka and Pella are identical in every possible way.

  • Parodied in the Futurama Soap Within a Show, All My Circuits, in which the main character is one of six identical septuplets.
  • Kim Possible's little brothers are identical twins who can only be told apart by the colour of their shirts.
  • The Sequel Series The Legend of Korra has Suyin's youngest sons, Wei and Wing. They have some minor accessory differences, but are otherwise completely identical.
  • The Raccoons: The three pigs who work for Cyril Sneer. They are identical in every way, even their clothes. The only way to tell them apart is their voices and the personalities that go with it.
  • Ingrid and Latoyah from Slacker Cats.
  • The Simpsons:
    • Sherri and Terri, two girls who go to the local elementary school and are in Bart's class.
    • Marge's older sisters, Patty and Selma Bouvier, are identical twins, so they're mostly the same in physical appearance and even their personalities; but their haircuts, dresses and even their sexualities are different (Patty eventually came out as a lesbian while Selma's heterosexual and has been married numerous times). Also, Selma has an adopted daughter from China named Ling and is the somewhat nicer twin; for example, when it comes to Marge's husband Homer, Selma has sometimes been shown to be a bit more willing to put up with him than Patty is.
      • It's revealed in one episode, however, that Patty and Selma are not identical. Their gray hair is actually the result of years of tobacco smoke and ash buildup; when they clear this debris from their hair, it's shown that one is blonde and the other has red hair.
  • Steven Universe: Jenny and Kiki are not specified as being identical, and they would never be mistaken for one another, but the differences are in their hair (which could just be a matter of styling it differently) and clothing, while their faces are the same shape and they share a voice actor.
  • The Twins in Superjail!, whose character models are literally copy and pasted most of the time.
  • The Scottish Twins from Thomas & Friends zigzag with this trope. In their backstory the twins intentionally removed their number plates so as to appear completely identical and pull a Twin Switch and escape from a railway that threatened to have them scrapped. After being employed at Sodor, though, they were given number and name plates, specifically so they could be told apart.
    • Soon after, the twin tank engines Bill and Ben were introduced, and often use Twin Switching to prank other engines.
    • Diesels Arry and Bert, but downplayed due to Bert's stubble.
  • The triplets in The Triplets of Belleville are basically the same type of characters.
  • From Total Drama, the 3rd Generation cast features Amy and Samey. In the spin-off Total Drama Presents: The Ridonculous Race, Mickey and Jay.

  • The Pet Alien episode "The Lookalike Girl of Evil" features Gabby's cousin Jabby. Jabby looks identical to Gabby (to the point of reusing her character model) but lacks her cousin's glasses and Mexican accent.

    Real Life 
  • The village of Kodhini, India has 6 times as many twins as the global average. On top of that, the majority of the twins are identical.
  • The Bella Twins had to take some steps to make this work when they started their identical twin model careers. As Nikki has a naturally more voluptuous frame than Brie, she had to do daily ab and cardio workouts to match her sister's waifier body type. As both twins turned 30, however, they abandoned this. Nikki got breast implants and started powerlifting. However even when they were identical, there were still notable facial differences that a good eye could spot.
  • Dueling advice columnists Abigail Van Buren and Ann Landers were identical twins; their real names were Esther Pauline and Pauline Esther. As teenagers, they pulled Twin Switch pranks frequently and even sometimes went on dates in each other's place.
  • Twinsburg, Ohio, a suburb of Cleveland, is named after twin brothers Moses and Aaron Wilcox, who were the town's biggest early investors. Since 1976, the town has hosted "Twins Days" in their memory, a weekend festival in August that has become the world's largest gathering of twins (and other multiple-birth siblings), drawing thousands from across the globe each year. As you can imagine, it is traditional for twins attending the event to dress alike (sometimes in costume) even if they're not identical.
  • June and Jennifer Gibbons were odd enough to be known as "The Silent Twins" by historians and psychologists alike. As sisters, they were unusually close, speaking only to each other, often holing up in their shared bedroom to write crime novels and refusing to leave, even for meals. During their eleven-year stint at Broadmoor Hospital, they reportedly made a pact that one of them had to die so the other could live a normal life. Sure enough, Jennifer died of an inflamed heart in 1993 and June has been living a relatively normal life since the death of her twin sister.
  • Nine-banded armadillos are always born as identical quadruplets, and the female can delay implantation of the embryo for several months until conditions are favorable.

Examples of Fraternal Twins (aversions):

NOTE: This section is reserved for twins who do not look alike at all; brother-sister twins who still look alike go to Half-Identical Twins.

    Anime & Manga 
  • Bleach: Yuzu and Karin Kurosaki are twin sisters but are the complete opposite of each other. Yuzu is a pale-haired homemaker who gets excellent grades in school. Karin is a tough, dark-haired tomboy who leads her male peers in football. Yuzu resembles their mother Masaki while Karin resembles their father Isshin.
  • Rin and Yukio Okamura from Blue Exorcist are fraternal twins who are opposites in pretty much everything, up to and including Rin being (half-)demon and Yukio being human. They look somewhat alike, but aside from Yukio wearing glasses, he's also a little taller and stockier than Rin.
  • Momiji and Kaede Fujimiya of Blue Seed are not only fraternal, they don't even resemble each other all that much. But their twinship is very important, because by being twins they split the power of the Kushinada.
  • Yukino and Kanade from Candy☆Boy are twin sisters but they aren't identical. Their hair colors are different and the way they style their hair differs.
  • In Corsair, fraternal twins Aura and Leti are clearly related yet distinct, with Leti taking much more after their father's side and Aura taking more after their mother's side.
  • Dragon Ball:
    • In Dragon Ball Z, Androids 17 and 18 are twins and do have some physical similarities (especially in the way their faces are drawn), but they have different hair colors and wear very different outfits.
    • Dragon Ball Super: It is revealed that there are twelve universes, but they are six pairs of twins. If the sum of their numbers is 13 (1+12, 4+9, 6+7, etc), those pairs are determined as twins. However, it is shown that Universe 7 and Universe 6 aren't identical. While both have a planet Earth, the Earth from Universe 7, which is the home planet of Goku and the others, is still full of life, while the Earth from Universe 6 is devoid of life due to the Earthlings blasting the entire thing in a devastating war.
      • Beerus and Champa, who are the Gods of Destruction of their respective universes, are both humanoid, purple cats. But Beerus is skinny, while Champa is fat.
  • Mairu and Kururi Orihara from Durarara!!, though they are sufficiently similar to possibly be just identical twins who decided to look different.
  • Food Wars!:
    • Averted in the case of Natsume and Orie Sendawara; Natsume is far more outspoken and aggressive than Orie, and tends to dress in quite provocative outfits, whereas Orie is calmer, meeker and tends to go for a cuter style. However, both of them are gourmets with extremely sensitive palates and have no hesitation whatsoever when it comes to shooting down unworthy efforts.
    • Defied in the case of the Aldini brothers, with several characters expressing shock at the fact that the two are even related, much less twins. Takumi is short, slender, blonde, artistic, sensitive and highly strung. Isami is tall, stocky (most of the time), brown-haired, calm, down-to-earth and practical. The only physical trait they seem to share is that both are blue-eyed, which is only noticeable when Isami is in "slim" mode.
  • Go! Go! Itsutsugo Land! averts the trope with a set of Quintuplets, all of which are radically different in appearance and personality.
  • Gundam SEED's Kira and Cagalli, being largely based on Luke and Leia. In addition to being non-identical, one is a genetically engineered superman and the other is completely unaltered.
  • In High School Star Musical Otori and Hiiragi are revealed to be not just brothers, but fraternal twins, separated by their grandfather, who needed an heir.
  • Kirio and Kirika from Kamichama Karin.
  • Kagami and Tsukasa Hiiragi from Lucky Star are fraternal twins who are drawn to have very different eye shapes (Tsukasa has Tareme Eyes and Kagami has Tsurime Eyes) and they also have different hairstyles. The fact that they're fraternal twins is even pointed out by Kagami. However, they have the same hair and eye color and look more similar to each other than to any of their other family members.
  • Lyrical Nanoha has Combat Cyborgs Otto and Deed, who are constantly referred to as the twins due to having been created from the same genes and born at the same time. While they act alike and are always together, they don't look alike, even having different height sizes, eye colors and shades of brown hair.
  • Magical Girl Site: It turns out Aya and Yastumura are these, with one having black hair and the other with blonde hair. This came as a complete shock to the main character, who just had her First Kiss with said twin sister.
  • It is unclear whether L and R Nomura of Marginal #4 are identical or fraternal twins. They have different hair colors, but that could be dyed (dandelion orange and lime green). R is 2 cm taller, but that could be due to other things.
  • Mitsudomoe has this with the main trio. They're triplets but look very different.
  • One Piece: The three sons who are born directly after Perospero are triplets: Katakuri, Daifuku and Oven. Aside from being massively huge and muscular, none of them resemble each other. They rather look like lost relatives of other characters instead. Their dissimilarity is even mirrored in their Devil Fruit abilities (Katakuri is a Logia-type user who can turn into mochi, Daifuku can summon a genie, and Oven has heat powers).
  • Suiseiseki and Souseiseki from Rozen Maiden are designed to be twins and they have the closest relationship among all seven sisters. While they do look similar, Suiseiseki has long hair and wears a green dress while Souseiseki has Boyish Short Hair and wears a blue suit. Their heterochromia also mirror each other's eye colors.
  • Bossun and Tsubaki from Sket Dance are eventually revealed to be twins who were Separated at Birth. Nobody noticed this before the revelation.

However, with proper modifications, they're apparently similar enough to perform a convincing Twin Switch.
  • Tengen Toppa Gurren Lagann has Jougon and Balinbow Bakusa, with blue and red eye colors.
  • To Love Ru:
  • Princess Fine and Princess Rein of Twin Princess of Wonder Planet.

  • In Zipman!!, Kaname and Koshiro are twins who look and act nothing alike. Kaname is a Book Dumb stuntman with whitish hair and a devilish face that earns him titles like "White Demon". Koshiro is a Teen Genius with gentle features and regular dark hair. The contrast is so startling that people can hardly believe they're related. It's even discussed by the judges who turned down Kaname for the role of Jackman.
    "His last name... Tatara."
    "You mean like that Tatara?!"
    "Could he be his brother?"
    "No, I doubt it. They don't look alike...

As shown in canon, Pinkie is a... pink-furred Earth pony mare with a dark pink mane and tail and a balloon Cutie Mark, while Marble Pie is a gray-colored Earth pony with a rock Cutie Mark. Upon becoming a demi-Draconequus goddess, Pinkie gained animal traits like a Golden Retriever's right front paw, a rabbit's left hind leg, an alligator's tail, a bluebird's left wing and a dragonfly's right wing, making her even more different than Marble.
    • Cernunnos and his younger sister, Rhiannon are labeled as fraternal divine twins by their respective entries, and thus have enough traits to differentiate them each other. Rhiannon is a dark blue-furred Deer doe with silver spots all over her body and face, smaller silver antlers, bright turquoise eyes, and a halo made of moonlight. Meanwhile, Cernunnos is a brown-furred divine Deer stag with darker brown accents, dark brown antlers gnarled like tree branches, blazing yellow-orange eyes and body markings, and a halo made of sunlight. Cernunnos gaining tree-like traits like leaves and bark on his antlers and body after receiving the domain of Rebirth and fusing with his dead older brother, Orion only served to widen the difference gap further.

They're pretty obviously brothers due to the blond hair, but one is tall and the other short. Then Oscar notices that the short one has silver eyes, meaning they're not twins at all—one is Yang's son and the other Ruby's.
  • Near the end of The Game of Three Generals in the Elemental Chess Trilogy, Roy and Riza become the parents of fraternal twins Brendan and Riana. The side volume Notes From the Grandmaster includes a Distant Finale which makes it clear that the twins look very different; Riana takes after their father and Brendan after their mother.

  • In Disney Fairies, Tinker Bell and Periwinkle are actually different races of fairies—apparently, fairies are created when a baby laughs, and the season that they're associated with depends on where the laugh "lands."

They have identical designs on their wings, however, as well as the same nose.

    Films — Live-Action 
  • Luke and Leia from the Star Wars saga. They were Separated at Birth after their mother died, to protect them from the Dark Side and particularly from their father, who had joined it. That's why they didn't know that they were twins when they first met each other and they have no resemblance to each other at all (he has light brown hair and blue eyes, she has dark brown hair and brown eyes). Granted, they were also established as twins later in the series, after the actors had already been cast.

But as it turns out, the "ghost" is Lady Chan's twin sister, who arranged the entire "haunting" to avenge her death.

  • In L. M. Montgomery's Anne of Green Gables series, among Anne and Gilbert's children are fraternal twins Anne and Diana, nicknamed "Nan" and "Di." Dark-haired Nan inherited her father's looks and her mother's wild imagination, while Di has her mother's red hair but in temperament is described as "very much her father's child." The fact that they are not identical baffles many of their peers and forms a minor plot point in Anne of Ingleside when a mischievous girl convinces the young Nan that all twins are identical, and the reason Nan doesn't look like her twin is that she was Switched at Birth.
    • Starting in Anne of Avonlea, Marilla fosters boy/girl twins Davy and Dora Keith, who are fraternal and Polar Opposite Twins in personality, as well. Davy is curious and always getting into trouble, while Dora is quiet and a rule-follower.

  • Kit and Holly Fielding in the Dick Francis novels Break In and Bolt.
  • One Lonely Night by Mickey Spillane.

  • Shadows of the Empire: Subverted. The Pike sisters, expert martial artists whom Xizor hires as assassins, look the same aside from their eyes: Zan's are green, Zu has one blue eye along with one green. This would technically make them fraternal-the book simply says they're "genetic twins".
  • What a Week has a rare case of fraternal twins of the same gender. Paul has a twin brother who looks nothing like him. Holly even said it's hard to believe they are related.

    Live-Action TV

  • The premise of Nicky, Ricky, Dicky, and Dawn with quadruplets instead of twins.
  • One of the big reveals in Heroes Reborn is that main characters Tommy and Malina are in fact, fraternal twins who were Separated at Birth. Why is this important to the show? Because they're Claire Bennet's children who were sent back in time to prevent Renautas Corporation from exploiting them - and because if the twins were raised together, Tommy's original ability of power absorption would have stolen his sister's ability as well. Their mother died in childbirth because he had inadvertently absorbed her regeneration.

  • For a series that's so out of touch with reality, you wouldn't expect Super Mario Bros. to feature realistic fraternal twins, but the heroes are, in fact, same-sex twins that look similar enough that they're clearly related, but different enough that they're easy to tell apart. Luigi was originally a Palette Swap of his brother, yet the Mario Bros. weren't canonized as twins until long after Luigi's Divergent Character Evolution.
  • The Sims 2 has a mechanic resetting how the parents' genetics and features are mixed after every birth, including between twins.

However, you can create identical twins in Create-A-Sim and Angela and Lilith Pleasant are existing identical twins.
  • While they are half identical in Final Fantasy IV, by The After Years, twins Palom and Porom have grown to look very different. Their earlier similarities can be justified by them originally being very young children, with puberty making their differences much more obvious.

Although they look similar, they are nowhere near Half-Identical Twins, as Carver is taller and has blue eyes in a more square-shaped face, while Bethany is brown-eyed and rather delicately featured. (Sharp-eyed players may notice that Bethany resembles their mother, Leandra, and Carver resembles Leandra's younger brother Gamlen.) They're also Polar Opposite Twins in terms of disposition; even the game makes note of their Red Oni, Blue Oni natures by giving Carver a reddish background in his icon while Bethany's is bright blue.
  • In the Dark Parables games, Prince Ross Red and Queen Snow White are immortal Polar Opposite Twins who don't look even remotely alike. Ross, who has fire-based powers, has red hair and red eyes; Snow, meanwhile, has frost powers and icy blue eyes. She used to be a brunette, but Power Dyes Your Hair white.

In the OVA for Kyou's route it takes Tomoya several minutes to realize that he's talking to Kyou and not Ryou after she cut her hair.
  • Haruka and Kanata of Little Busters! aren't identical, but they look similar enough that Kanata can impersonate Haruka, at least physically.
  • In Danganronpa: Trigger Happy Havoc, Mukuro Ikusaba and Junko Enoshima are fraternal twin sisters who look enough like each other with the right hairstyle, makeup and clothing that they can pass for each other, a fact used to switch Ikusaba for Enoshima, but there are enough physical differences like Ikusaba's Youthful Freckles that she has to brush off as being the result of her photographs being retouched when Naegi comments on it. If not using tricks, it's hard to tell that they are twins at all, considering that Enoshima has blond pigtails, round blue eyes, big breasts, and ceramic skin while Ikusaba has short black hair, narrow grey eyes, smaller breasts, and greyish pale skin. And even if Enoshima's blond hair is just dyed, her real hair color (red) would still be different from her twin sister's.
  • Sofiya and Natalya from Missing Stars have a Strong Family Resemblance but still look quite different from one another. Sofiya is quite a sum shorter than Natalya, wears her hair much longer, and their facial features are different.

Their eyes are slightly different shades of brown and Quintin's hair is dyed light green at the ends. They don't dress alike either, with Quintin wearing a simple hoodie and shorts while Jackie wears denim over a shoulderless blouse and short shorts. Rick is surprised to learn that Quintin is Jackie's twin, as they're fraternal twins who don't look identical, initially assuming that they're simply friends.
    Jackie: Hmm... have I never mentioned my twin brother?
    Rick: Twins...? But you guys don't look the same.
    [Beat Panel as Rick looks between the two of them]
    Jackie: Jeez! I sure hope not!
    Quintin: Hey!

  • Jackal and Hyena of Gargoyles both have brown hair and are completely Ax-Crazy, but that's where the similarities end.
  • In Transformers several characters are twins, and there's usually at least one pair in each continuity. However, they are never identical - at the very least they have strikingly different colours like Jetfire and Jetstorm in Transformers: Animated and other times they look different in many other ways, like Sideswipe and Sunstreaker in G1 - who even had radically different personalities. This is obviously for the purpose of making and selling more toys. Family relationships are actually rarely used to explain the Palette Swap characters, who get a more technical explanation if it's explained at all.
  • Hurricanes: Helmut and Yorg Beethoven. Helmut is taller and Yorg is more muscular.
  • Gravity Falls:
  • The Amazing Spiez!: Marc and Megan are twins, but they don't look any more related than they do compared to their older and younger brothers, and since the show's focus is on the team as a whole, the fact that they are twins is rarely mentioned or used as a plot point.

  • It's noted in The World of David the Gnome that gnomes always have twins when they have children. The trope is both played straight and subverted, however; some of the twins shown in the cartoon are identical, while others are fraternal.
  • Dora the Explorer - Dora's baby siblings are twin brother and sister and are given a decidedly different hairstyle.
  • Played with in DuckTales (2017)—the triplets apparently hatched from the same clutch of eggs (as did Donald and Della), but compared to the source material the three have distinct looks (mostly in regard to their "hair feathers") and personalities.
  • Space Ghost's sidekicks Jan and Jayce are a blonde girl and brown-haired guy.
  • The Wonder Twins, Zan and Jayna, on Super Friends were visually based on Donnie and Marie Osmond.
  • American Dad! episode "White Rice" reveals that Hayley had a twin brother named Bailey who died as an infant after Stan refused to vaccinate him. Bailey had auburn hair like Steve would later have rather than black hair like Hayley has.

    Real Life 
  • Not only does supermodel Nyle DiMarco look absolutely nothing like his twin brother Nico, they don't even appear to be the same race. Nyle has olive skin and straight black hair while Nico is a pale, curly ginger. The only sign that they're related at all is the deafness that runs in their family, as their parents and older brother Neal (who looks like he could be Nyle's fraternal twin) are all deaf.
  • Marcia and Millie Briggs actually play with this trope. They're biracial twins who each resemble a different parent appearance-wise, hence the news reporting them as "black and white twins." But once you get past the obvious differences, their facial features are every bit as similar as you would expect from sisters.
  • Perhaps the ultimate subversion of this trope would be Mary-Kate and Ashley Olsen. Despite playing identical twins in all their screen roles (save for Full House where they took turns playing the same character), they're actually fraternal twins. However, they look so similar that they've been mistaken for identical their entire lives.
  • Similar to the Olsens are The Usos, who are fraternal twins, but look similar enough that it can be difficult to tell them apart. The fact that they change their appearances often doesn't help.
