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 WikiWalk through TwinTropes. We'll wait.

Welcome back! So why are fictional twins always identical? Well, for starters, identical twins are visually striking. They allow for [[TwinSwitch comic plots]], and they add [[PlotParallel symmetry]] and [[RuleOfSymbolism symbolism]] to a story. An EvilTwin is almost always an Identical Twin; how else could they [[SpotTheImpostor impersonate the "good" twin]]? Fraternal twins, for all intents and purposes, are just regular siblings, and [[RuleOfDrama 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 are [[UntoUsASonAndDaughterAreBorn different genders]]-- HalfIdenticalTwins shouldn't even ''be'' identical! Though it is certainly possible for fraternal twins to bear a StrongFamilyResemblance, particularly in early childhood.

There are sometimes aversions, almost exclusively in live action productions where twin actors or DoubleVision are not available. The main ''subversion'' of this trope is NonIdenticalTwins, when twins are [[InformedAttribute said to be]] identical but are obviously not.

Identical twins are highly prone to [[SpeakInUnison Speaking In Unison]] or FinishingEachOthersSentences.

Keep in mind if the twin [[LongLostRelative isn't established at the beginning]], prepare for rage from the fandom.

Chalk this up to the LawOfConservationOfDetail -- if they're not identical, there's usually no need to establish them as twins rather than just siblings.

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?

[[folder:Advertising]]
* In a recent series of commercials for State Farm insurance, Los Angeles Clippers point guard Chris Paul plays both himself and his (fictional) SeparatedAtBirth twin Cliff, an insurance agent who was likewise born to assist.
[[/folder]]

[[folder:Anime & Manga]]
* Fujio Akatsuka's ''Osomatsu Kun'' is about identical ''sextuplets''. Yes, SIX characters that look exactly alike. The running gag in the early episodes was that other characters couldn't tell which is which.
* ''OuranHighSchoolHostClub'' has the Hitachiin twins, who are so alike that no one had ever been able to tell them apart until they met Haruhi. 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.
* ''TsubasaReservoirChronicle'' has [[spoiler: 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 [[spoiler: Syaoran and Syaoran]]. In the actual series they're [[spoiler:clones]] but the AlternateUniverse extra portrays them as identical twins. To make it even weirder in the main series [[spoiler:Syaoran]] technically ''does'' have a twin -- [[spoiler:[[{{xxxholic}} Watanuki]]]], but the two of them are not identical at all.
* It is fairly common in most harem-type series to have a pair of identical twins as part of the cast.
* 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. However after Agon gets a haircut, everyone is amazed to see he and his brother are very much identical.
* ''Manga/AirGear'' has identical ''[[UpToEleven octuplets]]'', complete with [[CoordinatedClothes identical outfits]].
* [[spoiler:Shion Sonozaki]] from ''VisualNovel/HigurashiNoNakuKoroNi'' uses this to her advantage, as she assumes her sister's identity to manipulate [[spoiler:as well as to cover up murder]] in the Watanagashi and Meakashi arcs.
* ''Manga/{{Naruto}}'' features two sets of identical twins (Hiashi and Hizashi and Sakon and Ukon). Coupled with [[SelfDuplication Shadow-Clones]] and GenerationXerox, Masashi Kishimoto seems fond of twins... [[JustifiedTrope then again]] he himself is one, and his younger twin Seishi [[Manga/SixSixSixSatan is also]] [[Manga/BlazerDrive a mangaka]].
* Yoh, the protagonist of ''Manga/ShamanKing'', is revealed to be the identical twin of Hao, the Big Bad of the series.
* Played with in ''Manga/{{Maomarimo}}'': Mao and Ako remain fraternal twins even after Mao's GenderBender, but the issue is raised by a background character who wonders why this trope wasn't invoked when Mao became a girl. Technically, Mao [[NotBloodSiblings 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.
* Takuma and Kazuma from ''Manga/GakuenBabysitters'' 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.
* One episode of ''Anime/SherlockHound'' has Sherlock and Watson dealing with a pair of twins, one is a navy commander and the other is an insane treasure hunter.
* ''Manga/{{Gunnm}}'' has [[GratuitousGerman Elf and Zwölf]], [[YouAreNumberSix AKA AR/GR-11 and AR/GR-12]] respectively, android clones of Gally, who inexplicably behaves as if they were identical twins, and often fill the role of Gally's {{Annoying Younger Sibling}}s.
* ''ArmoredTrooperVotoms'' features the Schmittel twins, who are (at first) only differentiated by their uniform color and voices. Even so, [[OffModel the animators were incredibly prone to slip up at remembering which one was which]].
* Played with in ''Anime/BloodPlus'': [[OurVampiresAreDifferent Chiropteran queens]] are always born in pairs, with [[RedOniBlueOni one having red eyes and one having blue eyes]], but otherwise the two are completely identical.
* ''{{Futakoi}}'' is all about this trope. There are ''six'' pairs of identical twins in the same series.
* In ''{{Manga/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''.
* ''Manga/{{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. [[spoiler: [[EliteMook 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, [[WalkingSpoiler Royd]] is mimicking [[TheEmperor 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.]]

** In the [[BadFuture Dark World]], Apple Pie had an identical twin named Poison Apple, though they had different Cutie Marks. Unfortunately, Poison Apple was killed by Fluttercruel.
* [[http://mrmenoc.wikia.com/wiki/Little_Miss_Conjoined Little Miss Conjoined]], two [[ConjoinedTwins conjoined]] ''Literature/MrMen'' fan characters, are completely identical except for the color of their noses (one has a yellow nose and one has a green nose).

[[folder:Film]]
* There are identical twin brother cops in ''Film/HotFuzz''-- [[spoiler:the Sergeants Turner (Bill Bailey's characters)]].
* Mary Kate and Ashley Olsen in everything they've done (except ''Series/FullHouse'', where the twins both played the same one character to stretch limits on how long very young child actors are allowed to work). They're actually fraternal twins, but look alike enough for identical-twin plots to work. However, as is often the case they started growing out of their StrongFamilyResemblance as they approached adulthood.
* The Twins from ''Film/TheMatrixReloaded''.
* Both versions of ''Film/TheParentTrap''.
* In ''Film/PacificRim'', the Chinese pilots of Crimson Typhoon are played by real-life identical ''triplets'' the Luu Brothers. As well, the American Jaeger pilots of Romeo Blue, Bruce and Trevin Gage, were identical twins.
* ''Film/ThePrestige'': [[spoiler: Borden and Fallon]].
* The Stabbington Brothers in ''Disney/{{Tangled}}''.
* A pair of elderly women twins appear in the French film ''Film/{{Amelie}}'', buying food at the local fruit stand. They also [[FinishingEachOthersSentences Finish Each Other's Sentences]].
* ''Seconds Apart'': Seth and Jonah are identical twins who use their telepathic abilities to commit murders.
* Eli and Paul Sunday of ''Film/ThereWillBeBlood''.
* This was the main driving force behind the plot of Cronenberg's ''Film/DeadRingers''.
* In ''Film/RoomInRome'', Natasha/Sasha/whatever her name is has an identical twin.

[[folder:Literature]]
* ''Literature/HarryPotter'': Fred and George Weasley and the Patil sisters.
** 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.
* The main character and his brother from ''Literature/TheSpiderwickChronicles''
* The main characters of the ''Literature/TWitches'' series.
* Jessica and Elizabeth Wakefield of ''Literature/SweetValleyHigh''. Not to mention 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 twins' ''parents.''
* Subverted in ''Literature/HonorHarrington'': while Detweiler brothers look like identical sextuplets, they are, in fact, ''clones'' of their father.
* Elladan and Elrohir of ''Literature/TheLordOfTheRings'' are not outwardly stated as being twins or even identical, but because their birth year is the same and elves wait at 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." This implies that they are identical twins (ignoring the fact that more elves are described like that than not, and quite a few humans!)
** Tolkien also has Amrod and Amras, the youngest sons of Feanor from ''Literature/TheSilmarillion'': "twin brothers, alike in mood and face."
* Lampshaded in ''Literature/ChroniclesOfTheKencyrath'', where the Edirr produce so many twins they usually do everything in twos.
* "The twins" ([[NoNameGiven No Names Given]]) in ''Literature/PeterPan'', "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 ''PeterPanAndThePirates'' [[SubvertedTrope 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 [[ThoseTwoGuys are always together]] and finish each other's sentences.
* [[PolarOppositeTwins Jory and Nia]] from [[Literature/CircleOfMagic Cold Fire]].
* Little Miss Twins from ''Literature/MrMen''.
* Lottie and Lisa in Erich Kästner's novel ''Das doppelte Lottchen'' who are so identical-looking that when they switch places, their own parents don't realise they've gone home with the wrong child, even though they don't even like the same food, aren't good at the same things at school, and Lisa doesn't know how to cook.
* EnidBlyton's ''Literature/StClares'' series has twins Pat and Isabel O'Sullivan. They do look alike, but their classmates can recognize them.
* Nypre and Deren, the first two characters introduced in the ''Literature/StoriesOfNypre'' are identical twins, though its never been said if they are so identical as to be indistinguishable from one another.
* RobertAHeinlein seems to have liked this trope; not only are there the Stone twins in ''The Rolling Stones'' but Lazarus Long's twin sister-daughters (clones) in ''Time Enough For Love''
* In [[Literature/TheHungerGames Mockingjay]] the Star Squad includes identical twin sisters whose first names are never revealed. Katniss and the other characters simply refer to them as "Leeg 1" and "Leeg 2".
* Averted in ''Literature/FirstLight'' when Thea was told that the three girls on her locket were Lana, her mother, and [[spoiler: her mother's twin who left the community with her twin.]] This was important because there could [[PopulationControl only be two girls born to any mother]].

[[folder:Live Action TV]]
* Tia Landry and Tamera Campbell on ''Series/SisterSister'' are long-lost identical twins, played by real life twins Tia and Tamera Mowry.
* Emily and Katie Fitch from ''Series/{{Skins}}'' are Identical twins, played by Real Life twins Kathryn and Megan Prescott respectively.
* Zack and Cody on ''Series/TheSuiteLifeOfZackAndCody'', also played by Real Life twins. Puberty made them not so identical.
* The title characters of ''Series/LivAndMaddie'' are, by contrast, played by one actress, Dove Cameron.
* Nearly every set of twins in ''Series/ThePretender'', 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 co-ordinated outfits.
* ''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.
* {{Friends}}: Phoebe and Ursula.
* Series/OutrageousFortune. Van and Jethro West. Both with [[TheDitz wildly]] [[AmoralAttorney contrasting personalities]].
* ''Series/PeterPunk'': The Pop twins Andy and Michael.
* ''Series/PowerRangersZeo'' has the character Trey of Triforia (also known as the original [[SixthRanger 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.
* The ''Series/DoctorInTheHouse'' franchise features two examples, achieved via ActingForTwo (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 [[FreudianExcuse 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).
* ''Series/GuidingLight'': Lujack Luvonaczek and Nick Spaulding.
* ''Series/AnotherWorld'': Marley and Vicky Hudson.
* ''Series/AllMyChildren'': Adam and Stuart Chandler.

[[folder:Video Games]]
* Dante and Vergil from ''VideoGame/DevilMayCry'', of the [[RuleOfSymbolism symbolism-heavy]], CainAndAbel, PolarOppositeTwins variety. You can tell them apart because Vergil [[GoodHairEvilHair slicks his hair back]], but they're also ColorCodedCharacters: [[RedOniBlueOni Vergil wears blue, Dante red.]] Two other pairs are [[PlayingWithFire Agni]] [[DualBoss and]] [[BlowYouAway Rudra]] from ''3'', and [[FrogsAndToads Bael]] [[AnIcePerson and]] [[AlluringAnglerfish Dagon]], a pair of [[OurDemonsAreDifferent frog demons]] in ''4'', the latter of whose in-game information even points out that, [[PaletteSwap aside from their color,]] they are identical in terms of abilities and weaknesses.
* Redmond and Blutarch from ''VideoGame/TeamFortress2'', you can only tell them apart because [[ColorCodedCharacters Redmond wears a red suit and Blutarch wears a blue suit]]
* Ami and Mami Futami of ''VideoGame/TheIdolmaster''.
* Enter and Return in LEGOIsland
* Koume and Kotate from TheLegendOfZelda series. Identical apart from the gem on their forehead being different colours. ''ALinkToThePast'' also featured Twin Lumberjacks and due to the model reuse in ''MajorasMask'' there's at least three sets of twins identical in everything but clothing colour.

* ''Webcomic/TheOrderOfTheStick'': Elan and [[EvilTwin Na]][[SdrawkcabName le]].
* ''LegostarGalactica:'' Bob and [[EvilTwin Rob]] [[MrSmith Smith.]] [[spoiler:Subverted in that Rob is an [[EvilTwin evil]] [[CloningBlues clone]] of Bob created by the Remulans as part of an abandoned infiltration plot.]]
* ''SailorSun'' Bay(Brad) and Heather after Bay's GenderBender. We don't know if they were HalfIdenticalTwins prior to the GenderBender because Brad has never been depicted in the comic. It's even a plot point because in [[AllThereInTheManual the backstory]] Bay & Heather found each other (they'd been SeparatedAtBirth) after Heather was hired to play Bay's role in a touring production of Sailor Sun based on her identical appearance.
* ''Webcomic/ElGoonishShive'' plays with this: [[spoiler: 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.

* The [=DeeDees=] (real names Delia & Deidre Dennis) from ''WesternAnimation/BatmanBeyondReturnOfTheJoker''.

* KimPossible's little brothers are identical twins who can only be told apart by the colour of their shirts.
* The Scottish Twins from ''ThomasTheTankEngine'' zigzag with this trope. In their backstory the twins intentionally removed their number plates so as to appear completely identical and pull a TwinSwitch and escape from a railroad 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.

* [[spoiler:"Syaoran Li" and "Watanuki Kimihiro"]] aka [[spoiler: "Tsubasa Li 1" and, presumably, "Tsubasa Li 2]] of ''TsubasaReservoirChronicle'' and ''Manga/{{xxxHoLic}}'' are a particularly notable example, being that they're not identical despite one of them being a time travel duplicate of the other.
* ''[[Anime/MobileSuitGundamSeed Gundam SEED]]'''s [[spoiler: Kira and Cagalli, being largely based on [[Franchise/StarWars Luke and Leia]]]]. In addition to being non-identical, one is a genetically engineered superman and the other is completely unaltered.
* Kagami and Tsukasa Hiiragi from ''Anime/LuckyStar'' are fraternal twins who are drawn to have very different eye shapes (Tsukasa has TaremeEyes and Kagami has TsurimeEyes) and they also have different hairstyles. However, they do look more similar to each other than to any of their other family members, at least as far as their hair and eye colors are concerned.
* ''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.
* [[SingleMindedTwins Mairu and Kururi]] [[spoiler:Orihara]] from ''LightNovel/{{Durarara}}'', though they are sufficiently similar to possibly be just identical twins who decided [[PolarOppositeTwins to look different]].
* Rin and Yukio Okamura from ''[[Manga/BlueExorcist Ao No Exorcist]]'' are fraternal twins who - despite looking somewhat alike when you take away Yukio's glasses - are opposites in pretty much everything, up to and including Rin being (half-)demon and Yukio being human. This didn't stop the fandom from going nuts with {{Twincest}}.
* Princess Fine and Princess Rein of ''Anime/FushigiboshiNoFutagohime'' (Twin Princesses of the Mysterious Star).
* Kyou and Ryou Fujibayashi of ''VisualNovel/{{Clannad}}'' are similar to Kagami and Tsukasa Hiiragi in that Ryou has TaremeEyes and Kyou has TsurimeEyes. Though they're more alike than most fraternal twins with similar colored hair and eyes [[spoiler: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.]]
* Momiji and Kaede Fujimiya of ''BlueSeed'' 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,
* [[spoiler: Bossun and Tsubaki]] from ''Manga/SketDance'' are eventually revealed to be twins who were SeparatedAtBirth. Nobody noticed this before the revelation. Especially since [[spoiler: Tsubaki is characterized by his long eyelashes, which Bossun don't have, and he also wears contacts]], making them look less similar than they should be. However, with proper modifications, they're apparently similar enough to perform a convincing TwinSwitch.
* ToLoveRU has two sets of twins, but neither set is identical. Ren and Run are the result of a LiteralSplitPersonaility and look nothing alike.
** [[PolarOppositeTwins Nana and Momo]] look like sisters, but are obviously distinct. They pull off a TwinSwitch at one point using their sisters FreakyFridayFlip [[AppliedPhlebotinum machine]].

* In Creator/LMMontgomery's ''Literature/{{Anne of Green Gables}}'' series, Anne and Gilbert's twins, Nan and Di, are fraternal. They are opposite in looks, with Nan taking after Gilbert and Di taking after Anne. They also differ in personality. Di is mentioned as being "very much her father's child", while Nan inherits her mother's wild imagination. The fact that they are not identical forms a minor plot point in ''Anne of Ingleside'', in which a mischievous friend convinces the young Nan that all twins are identical, and the reason Nan doesn't look like her twin is that she was SwitchedAtBirth.
** In ''Anne of Avonlea'', Anne's foster mother Marilla adopts the twins Dora and Davy.

* Buffy and Jody from ''FamilyAffair'' were fraternal twins.
* [[spoiler:Miss Parker and Mr Lyle]] in ''ThePretender''.
* Brenda and Brandon Walsh ''BeverlyHills90210'' are fraternal twins.

Ridge and Taylor's daughters Steffy and Phoebe were identical twins and played by identical twins up until the point where the characters left for London. Phoebe is the first to return, now played by a new actress. When Steffy returns a while later she is played by a different actress than Phoebe and the twins are now fraternal.

* For a series that's so out of touch with reality, you wouldn't expect ''Franchise/SuperMarioBros'' 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.
* ''VideoGame/TheSims 2'' has a mechanic resetting how the parents' genetics and features are mixed after every birth, including between twins. Identical twins are thus impossible unless that mechanic is glitching (which is not uncommon).
** However, you can create identical twins in Create-A-Sim and Angela and Lillth Pleasant are existing identical twins.
* Lucas and Claus from ''VideoGame/{{Mother 3}}''. Based on in-game evidence, they're still similar enough that you ''can'' confuse the two if you don't know them well. What really gives them away, though, is their hair; Lucas is blonde, Claus is a redhead.

* ''WesternAnimation/TheVentureBrothers'' has two sets of fraternal twins. Jonas Junior & Thadeus and Hank & Dean, the latter two being the title characters.
* Jackal and Hyena of ''WesternAnimation/{{Gargoyles}}'' both have brown hair and are completely AxCrazy, 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 ''TransformersAnimated'' 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 [[MerchandiseDriven for the purpose of making and selling more toys.]]
* ''{{Hurricanes}}'': Helmut and Yorg Beethoven. Helmut is taller and Yorg is more muscular.
