->'''Sam:''' Just because they're twins doesn't automatically make them creepy!
->'''Gary:''' It does a little bit...
-->-- ''Film/TheWorldsEnd''

Although casting twins on TV are rarely incidental, this is a specific non-comedic use of identical twins who tend to speak, move, and act in tandem just enough to weird out the audience. Usually relegated to villainous or morally ambiguous characters. They may even display an intense, [[{{Twincest}} very intimate fondness for each other]].

Especially creepy versions may show what amounts to a psychic affinity with each other, being able to finish one another's sentences or divine what the other is thinking/doing when not present.

See also {{Synchronization}}, FinishingEachOthersSentences, CreepyChild, EmotionlessGirl, [[IncestIsRelative Incest]], {{Twincest}}, TwinTelepathy, BrotherSisterIncest, HoYay. Not the same as EvilTwin.

HalfIdenticalTwins can sometimes make this category, especially when they try to look like each other (or switch off with the other twin), and trick people.

[[folder:Advertising]]
* Seen in [[http://www.youtube.com/watch?v=57Us8Q10Sks one of]] the Verizon "Dead Zone" ads. They SpeakInUnison and try to be creepy, but because the guy has a Verizon phone...
[[/folder]]

[[folder: {{Anime}} and {{Manga}}]]
* Hansel and Gretel from ''Manga/BlackLagoon'' take this trope to [[UpToEleven a whole new level]]. While initially they are fairly distinctive (one is a boy, and one a girl) despite similar looks and personalities, it is later revealed that they [[spoiler:swap the roles of 'boy' and 'girl' around as they please; Hansel wears his sister's clothes, a long-haired wig (both the twins actually have short hair), carries her weapon, and takes on her voice and personality, while Gretel does the same with Hansel's personality. The twins' gender is never actually revealed, which just adds to the confusion.]] Not to mention they just ''love'' killing people, just because they can. They also like to "play" with their victims. Is it surprising that everybody in the anime compares them to the twins from ''Film/TheShining''? In the manga, "Gretel" even sings the tune that plays over ''Film/TheShining'''s end credits.
** They also actively practice {{Twincest}} and were made to work as underage porn stars in snuff films. It's highly suggested that they just... broke... as a survival mechanism.
** Not to mention their disturbing optimism which centers around the deaths of others, which they cling to even as [[spoiler:they die themselves]].
* The twin girls Xia Yu Fang and Xia Yu Lan from ''LightNovel/FullMetalPanic The Second Raid''
** They were ''[[GenderFlip actually boys]]'' in the novel.
* Another anime example in ''Aim for the Top 2! DieBuster'' with the Serpentine twins.
* The Hitachiin twins, Kaoru and Hikaru, from ''Manga/OuranHighSchoolHostClub'' finish each other's sentences and use (implied) {{twincest}} as their schtick. They're played for laughs.
** Don't forget, sometimes they also speak and move in unison as well.
** In the anime, they also have a pair of (female) twin maids who do the exact same thing. They're just like the brothers, only they can get away with being in the changing room with Haruhi.
* ''Anime/CodeGeass'' has [[spoiler: Charles Vi Brittainia and his brother, V.V.]] although they don't look it, [[spoiler: since one has stopped aging after becoming immortal.]]
* In ''Dragon Drive'' a VillainOfTheWeek is a pair of male and female twin children who seem unnaturally sadistic because of being spoiled brats, but turn out to be [[spoiler:possessed]].
* Luki and Noki from ''Manga/DogsBulletsAndCarnage'' tend to avoid this most of the time, as while they're in sync, quite AxCrazy, and very good at their job as {{Bounty Hunter}}s, they're also quite genuinely cheerful and when they're off the job, they're just like normal children. However, after being {{Brainwashed|AndCrazy}} and possibly {{Mind Rape}}d twice in quick succession, they become this. They chuckle softly, speak in dead monotones, and the synchronization that was once cute becomes unnerving.
* Jasdero and Devit in ''Manga/DGrayMan'', who prefer to be referred to collectively as Jasdevi. They can also combine into one person. They also hang perilously over the UncannyValley. They also use WonderTwinPowers. And have PrehensileHair.
* The Liebert twins, Nina and Johan from ''Anime/{{Monster}}'', at least when they were children. Nina has since grown up to be a hardworking and productive member of society, while Johan has grown up to be a sociopathic manipulator and mass murderer who has been compared to UsefulNotes/AdolfHitler and the devil himself.
* Those creepy Bount twins in ''Manga/{{Bleach}}''.
** [[spoiler: Loyd and Royd Lloyd from the Vandereich]] are even creepier.
* Belphegor and Rasiel from ''Manga/KatekyoHitmanReborn''. Also, the Bloody Twins Jiji and Djidji.
* [[spoiler: 0010+ and 0010- ]] in {{Cyborg 009}}. A small subversion, since [[spoiler: the twins are * full-grown adults* and not children/teens as usual.]]
* The Watahiko children in ''Manga/{{Mushishi}}''. While not actually twins, they pretty much look the same, and share a single mind. [[spoiler: Or more accurately drones/appendages of a single entity. The real Watahiko is a sentient fungus.]]
* The Sonozaki twins in ''VisualNovel/HigurashiNoNakuKoroNi''. Though they're not really creepy as a pair, they each have their own distinct creepiness.
* Sae and Yumi from ''Manga/AsatteNoHoukou''.
* ''MuhyoAndRoji'' has Lili and Maril. They know too much, and behave suspiciously even after they help Roji fight some evil spirits.
* The [[http://media.onemanga.com/mangas/00002702/000190072/03.jpg twin hair stylists]] of the salon [[Manga/HidamariSketch Yuno]] went to scared the heck out of her.
* ''Manga/TsubasaReservoirChronicle'', with the vampire twins Subaru and Kamui who are [[spoiler: running away from a psychotic Seishiro for poorly explained reasons]], and the "cursed twins," [[spoiler: Fai and Yuui]]. When the latter twin became convinced that he [[spoiler: killed his brother thanks to BigBad's MindRape,]] he [[spoiler: took his brother's name]] and became the series's biggest angst muffin.
* ''Manga/{{xxxHOLiC}}'': Moro and Maru, Yuuko's two assistants at the shop. It's revealed early on that they have no souls, and later, that they keep the shop grounded between dimensions.
* ''Manga/DeadmanWonderland'': Ichi and Hajime, [[spoiler: who at first seemed to be a single, creepy Forgery kid with a lollipop]].
* ''Manga/{{Loveless}}'': Yoji and Natsuo, who, despite not being actual twins, certainly fit aspects of this trope and usually act like one mind.
* ''Anime/{{Kakurenbo}}'': Inmu and Yanku. They never speak, have glowing red eyes and act together a lot. They seem to have supernatural qualities without being supernatural, such having a strong sense of smell and being real fast. Also, you don't even know who's who - it may be believed Inmu is the one in red, but that's never been verified.
* Mairu and Kururi [[spoiler:Orihara]] from ''LightNovel/{{Durarara}}''. Usually they're harmless, if weird. ''[[BewareTheNiceOnes Usually]]''. [[CutePsycho Please don't provoke them.]]
* Sakon and Ukon from ''Manga/{{Naruto}}'' take this to [[UpToEleven exteme levels]]. They usually share Sakon's body.
* [[spoiler:Nene and Nono Motoe]] in ''Anime/BloodC''.
* Souya and Shirase aka [[spoiler: (the cute boys who work as Sanetoshi's assistants)]] in ''Anime/MawaruPenguindrum''.
* In ''Anime/YuGiOh'' Yami Bakura's later deck includes a magic card called "Cursed Necro Twins", or "Cursed Twin Dolls" in the dub. The illustration includes two ghastly looking girl twin dolls holding presents. When one player chooses a present, the other player is forced to choose the remaining one. The card is meant to manipulate Bakura's card graveyard.
* ''SpaceRunawayIdeon'' has the twins of the Buff Clan, a pair of short-lived villains who attempt to destroy the Ideon.
* Arron and Gurran Schmittel in ''ArmoredTrooperVotoms'', a pair of cryptic, cold scientist brothers who nevertheless take amusement in seeing how they can experiment in increasing Ypsilon's negative emotions. They even initially tend to [[FinishingEachOthersSentences finish each others' dialogue]], when they're not engaged in sibling banter.
* Otto and Deed, the Combat {{Cyborg}} twins of ''Anime/MagicalGirlLyricalNanohaStrikerS'', who are rarely separated and are two of the most [[EmotionlessGirl emotionless]] members of the [[QuirkyMinibossSquad Numbers]].
* Androids 17 and 18 from ''Anime/DragonBallZ'' are like this, at first.
* The Infant and Hakudoshi in ''Anime/InuYasha''. Both twins are nearly as sadistic as Naraku himself, to the point that they [[spoiler:attempt to overthrow him.]] Their childlike appearance makes them look relatively harmless, a mistake that most of their enemies made.
[[/folder]]

[[folder:Comic Books]]
* The series ''Comicbook/{{Kabuki}}'' featured twin assassins collectively named Siamese -- former Siamese twins joined at the shoulder, and given cybernetic arms when surgically separated. They're portrayed in a fairly creepy fashion; although they do get a sympathetic scene at one point in the series, it's somewhat negated by the fact that the left-handed one is busy sewing all her stuffed animals' mouths shut at the time.
* [[MarvelComics Fenris (the collective name of Andreas and Andrea von Strucker)]] had superpowers, but only when in contact with each other. As such, they were often found holding hands. As if that weren't enough, [[spoiler:Andrea died, so Andreas had her skin tanned and made into a leather grip for his sword so that he could maintain his powers.]] Ick.
** Later, [[spoiler: Andrea was resurrected, so Andreas had the skin flayed from his arm and given to her.]] Those crazy kids.
* At one time, {{Deadpool}} fought against two Britney Spears-esque twin sisters called "Mercy Sisters". They didn't finish each other's sentences, but they sure were creepy.
[[/folder]]

[[folder:Film - Animation]]
* The eels Flotsam and Jetsam from ''Disney/TheLittleMermaid'' fall under this trope. True, they may or may not be twins, (One eel looks pretty much like another.) but the scene where they talk Ariel into going with them to see Ursula is pretty creepy.
** It should also be noted that one of them is blind in his left eye, and the other in his right.
* Another Disney example: Si and Am from ''LadyAndTheTramp''. Is that song [[{{Earworm}} stuck in your head yet?]]
[[/folder]]

[[folder:Film - Live Action]]
* One of the most famous examples in the Western world would be the creepy sisters from Stanley Kubrick's film version of ''Film/TheShining'' (though their ages are stated as different in the film -- 8 and 10 years -- they look identical and are actually played by twins). They were based on a photo of a set of twins taken by Diane Arbus.
* Another well-known example from Western movies: "The Twins" from the ''[[Film/TheMatrix Matrix]]'' trilogy.
** Although, quite frankly, they'd be creepy even if there was just one of them.
** We're guessing the [[EvilAlbino albino factor]] doesn't help either.
* The Twins Wendell and Darlene in ''Film/TheHamiltons'', who also engage in {{Twincest}}.
* The twin sprites whose singing summons Mothra in the various ''Franchise/{{Godzilla}}'' and ''Film/{{Mothra}}'' movies (their spoken dialogue switches back and forth from speaking-in-unison to finishing-each-other's-sentences).
** Later subverted in the ''Film/RebirthOfMothra'' movies, in which they're turned into an OddCouple of an emotional twin, and an intellectual twin.
** The original twins weren't creepy at all, but very sweet. Their odd speech patterns were explained by the fact that they were really communicating by telepathy.
* ''Film/DeadRingers'', creepy twin surgeons played by one actor (Creator/JeremyIrons) and a boatload of FX.
* In some instances, the creepy twin effect is caused by a split brain situation, where each twin has half of the same brain. Some examples include the film ''SlapstickOfAnotherKind'', and the movie ''The Nightmare Before Christmas''. It also occurs in the novel ''The Singers of Time'' due to a set of conjoined twins sharing one brain at birth, who are then separated.
* The Nicolas Cage remake of ''TheWickerMan'' features a pair of creepy ''old'' female twins.[[http://www.youtube.com/watch?v=v_mW8mBzmHo]]
* The main characters of a creepy Japanese film called ''Wool 100%''. They're at least 60 years old, live in an isolated junk-filled mansion, and still dress the same as when they were teens (one wears only blue kimonos, the other green western dresses). Them coming to terms with their ItsAllJunk - filled house starts when a little girl suddenly materializes from a ball of red yarn.
* ''Franchise/{{Hellraiser}}'':
** In ''Film/HellraiserBloodline'' there were the Siamese Twins Cenobites, who were fused at the head and only ever emitted growling noises.
** In ''Film/HellraiserInferno'' there were the Wire Twin Cenobites, who also appeared as elderly human sisters. They were infinitely creepier than the bondage model cenobite versions.
* There were two silent vampire twins in Hammer Horror's ''Vampire Circus''.
* Mu-rong Yin and Mu-rong Yang in ''Ashes of Time'', brother and sister, apparently. They are very hard to tell apart, one time a character realizes only in the middle of the conversation that he's talking to the other twin. Both ask the same hitman to kill the respective other. Turns out [[spoiler: they are two personalities in one body, eternally fighting]]
* ''Film/HarryPotter and the [[Literature/HarryPotterAndTheHalfBloodPrince Half-Blood Prince]]'' has creepy twins in the background. They are not in the book. The movie adds them on to build a darksome atmosphere.
* ''TromasWar'' has creepy ''Siamese'' twins, joined at the head, one with a ''high''-pitched voice, the other with a ''low''-pitched voice.
* ''The5000FingersOfDrT'' features a pair of roller-skating twins who share a conjoined beard, with which they attempt to strangle the protagonists.
* Killers in the SlasherMovie ''Film/JustBeforeDawn'' turn out to be a pair of hillbilly twins.
* The 2013 ''Carrie'' remake introduces twins Nikki and Lizzy who are part of AlphaBitch Christine Hargensen's clique.
* EdgarWright loves this trope: ''Film/ShaunOfTheDead'', ''Film/HotFuzz'' and ''Film/TheWorldsEnd'' all feature creepy twins as minor antagonists. [[DiscussedTrope Discussed]] in the latter, providing the page quote.
** [[DownplayedTrope Downplayed]] in ''ScottPilgrimVsTheWorld''; the Katayanagi Twins are antagonists and do move in tandem, but its not meant to be especially creepy like in the Cornetto trilogy.
[[/folder]]

[[folder:Literature]]
* The Sisters of Orion of Adam R. Brown's ''{{Literature/Alterien}}'' series exemplify this trope. The Sisters release Oberon from captivity and summon him to them. He follows the voices of what he believes to be adult women only to discover they are young children no more than 6 years old. The creep factor is played up even further by the fact they each speak in a generally cold and emotionless tone.
* The {{Duumvirate}} is already terror-inducing, so when they pull this off it only [[FromBadToWorse gets worse]].
* The mages Beltira and Belkira from David Eddings' ''{{Belgariad}}'' have a tendency for finishing each other's sentences (This was {{retcon}}ned in the {{prequel}}s, where they play a much larger role and speak and act normally). However, there is a ''slight'' difference between them, as Belkira would allow himself some ironic comments Beltira would never say. (Although they're good guys.)
* In Creator/FrankHerbert's ''Literature/{{Dune}}'' series, Leto and Ghanima most definitely apply.
* The Otter Clan Mage twins in ''TheChroniclesOfAncientDarkness''. Pale-skinned, pale-haired, white-eyed children, referred to not as "The Mages," but as "The Mage."
* Cora and Clarice from ''Literature/{{Gormenghast}}''. They're also a little sad and pathetic, but still, creepy.
* Ruby and Garnet in Creator/JacquelineWilson's ''Double Act'', who are nice girls really, engage in creepy-twin behaviour to freak out their dad's new girlfriend.
* José Arcadio Segundo and Aureliano Segundo from ''Literature/OneHundredYearsOfSolitude'' used to cultivate the Creepy Twins image and pull {{Twin Switch}}es as kids. Once, when their mom served them some lemonade, one of the kids tasted it and ''the other'' boy, who had not drank still, said it was unsweetened. Subverted, as they grow up to be PolarOppositeTwins (with José Arcadio Segundo as a taciturn ShellShockedVeteran and Arcadio Segundo as a BoisterousBruiser) [[spoiler: until their deaths]]
* While not so much creepy as a pair of {{Bratty Half Pint}}s, Marilyn and Carolyn Arnold made life hell for TheBabySittersClub. They got better once people began treating them as individuals.
* ''Literature/LordOfTheFlies'': Sam and Eric. While not too creepy initially, they form a super-close bond out of survival and by the end of the book they're basically one entity.
* The Weasley twins from ''Literature/HarryPotter''. They're harmless but unsettling, and sometimes take turns speaking to the point that they switch speakers at least five times a sentence. They're also not beyond pulling dangerous pranks on people, though [[JerkWithaHeartOfGold mostly if they think]] [[KickTheSonOfabitch their target deserves it]]. In [[Film/HarryPotter the films]], they're definitely kinda creepy. Synchronized {{Cheshire Cat Grin}}s!
** Spoofed in Creator/CleolindaJones' [[http://community.livejournal.com/m15m/15640.html Goblet of Fire in Fifteen Minutes]]:
--->[Meanwhile, the Weasley twins are taking bets on the champions’ survival:]
--->'''FRED (OR GEORGE):''' Three lads!
--->'''GEORGE (OR FRED):''' One lady!
--->'''FRED (OR GEORGE):''' Four go down—
--->'''GEORGE (OR FRED):''' —but do four come up?
** The Carrow siblings aren't twins, but they are physically similar (squat, short). They also share a creepy wheezing laugh and are sadistic Death Eaters. [[spoiler: And then in Deathly Hallows they become teachers at Hogwarts, teaching anti-Muggle propaganda and forcing kids to use the Cruciatus Curse against one another as punishment.]]
* The Twins in the ''Literature/InheritanceCycle''.
* Jane and Alec in ''Literature/{{Twilight}}''.
* In the ''Franchise/{{Disgaea}}'' [[LightNovel/DisgaeaNovels novels]] it is revealed that [[Characters/DisgaeaHourOfDarkness Laharl]] got twin cousins [[Characters/DisgaeaNovels Shas and Kira]]. They are small unpleasant buggers that try to kill him.
* Lucas and Claus from Agota Kristof's ''The Notebook, The Proof, And The Third Lie'' are like this mixed in with a case of TroublingUnchildlikeBehavior.
* Perdina and Voile Tricante in ''Literature/BuryingTheShadow'' always struck Rayojini as being more than a little odd as all they seem to do is [[IncestSubtext stay in their room]] and read strange poetry. Creepiness factor upped by them being [[OldMaid women in their mid-twenties]].
* Emmeline and Adeline March in ''Literature/TheThirteenthTale'' who speak their own twin language and don't realize that other people are real.
* Violet and Verbina in Dean Koontz' The Bad Place.
* Deek and Steward Morgan in Toni Morrison's ''Paradise'' are the psychic brand of creepy twins, seemingly never talking to each other, but always knowing what the other means, causing discomfort from the townsfolk.
* The twin black cats in ''Literature/VarjakPaw'', who are also seen in-universe as being in the UncannyValley.
* As time passes in ''Literature/FlowersInTheAttic'' and Cory and Carrie get sicker, they become more and more like this.
* The Twins in the ''Literature/LeagueOfMagi'' have the power of gods and regard humans as nothing more than fascinating insects. When they even notice them, that is.
* Mekare and Maharet, the Red-Haired Twins, of ''Literature/TheVampireChronicles'' first appear in the dreams of vampires and mortals alike all across the world, kneeling either side of a charred body, and [[ImAHumanitarian preparing to eat its cooked heart and brain]]. Even as the context is revealed and they quickly become [[TraumaCongaLine sympathetic]], they don't stop being creepy.
[[/folder]]

[[folder:Live Action TV]]
* The twins in the British comedy ''TheLeagueOfGentlemen'' who leave a man tied to a scarecrow, so they have someone to talk to. Their names are Chloe and Radclyffe Denton, they are implied to have PsychicPowers and OffscreenTeleportation, and they are [[DevilInPlainSight deceptively monstrous]].
** ''{{Spaced}}'' featured a pair of spooky twins in its first episode, but they were dropped after the writers discovered that ''The League Of Gentlemen'' has used the idea just before them.
* The murderous cloned girls who looked exactly like each other in ''Series/TheXFiles'' episode "Eve" definitely count. They looked especially hellish in their matching red outfits. Even though fostered to families on either side of the country, [[IJustKnew they are somehow aware of each other's existence]] and murder their fathers in an identical bizarre fashion in order to make contact.
* The twins April and June in the ''TalesFromTheCrypt'' episode "Split Personality". Let's see: Matching outfits? Check. Propensity to finish each other's sentences? Check. Spooky, unblinking, hollow-eyed stare? Check. Chainsawing a con man in half lengthwise --[[GroinAttack from the groin up]]-- so each one could keep half of him? Chec- actually, [[CruelAndUnusualDeath that last one goes well above and beyond the expectations of the trope]].
* The elderly twins Lassie sees in the hallway at night in an episode of ''{{Psych}}'' definitely count.
* The Dedek twins' roles in the short lived ''FourKings'' creeped out many on TelevisionWithoutPity.
* An episode of ''{{Smallville}}'' featured mutant twins, referred to by the leader of their trio as the "Wonder Twins" for yet another comic book MythologyGag. Not only did the two have identical grotesque appearances and [[TheIgor Igor-like]] mannerisms, [[WonderTwinPowers use their power by touching]], and finish each other's sentences (to the chagrin of their leader), but they also [[{{Synchronization}} shared pain]].
* In ''Joan of Arcadia'''s season one finale, God appears to Joan as a pair of twins ([[{{Satan}} or does he?]]). It is pretty effing creepy.
* The English twins on ''TheSuiteLifeOfZackAndCody'' are always repeating each other.
** Indeed, Zack and Cody themselves fit this trope as well.
** [[WebVideo/YuGiOhTheAbridgedSeries "Dude, I thought YOU were Cody!"]]
* Sam and David Camden from ''Series/SeventhHeaven''. They often finish each other's sentences and speak in unison.
* The scene where Boomer confronts her naked clones in the Season One finale of ''Series/{{Battlestar Galactica|Reimagined}}'' was this, [[MesACrowd writ large]].
* Gem and Gemma from ''Series/PowerRangersRPM'' border on this at times. They [[StepfordSmiler don't seem capable of any facial expression other than a delighted grin]], [[SingleMindedTwins don't seem capable of speaking without the other to help]], and [[CuteAndPsycho have a slightly disconcerting fondness for explosives]].
* A ShoutOut to Kubrick in ''ItsAlwaysSunnyInPhiladelphia'', when Dee sees ''Film/TheShining'' twins. Whether the building is haunted in addition to everything else wrong with it or she's hallucinating from Charlie's cocktail of coping substances isn't made clear.
* ''{{Jekyll}}'': [[spoiler: Claire and Tom's twin kids are mostly normal throughout the series, but at the end, it's ''strongly'' implied that they've inherited the Hyde personality from Tom... and may in fact represent the divide rather than keep it lurking within themselves. Such as when they get bored and "switch" while confined in cells the size of beer kegs.]]
* ''Series/DoctorWho'' has played with the trope a couple of times:
** Romulus and Remus in [[Recap/DoctorWhoS21E7TheTwinDilemma "The Twin Dilemma"]]. They're not evil, but they are spooky mathematical geniuses.
** In [[Recap/DoctorWhoS31E1TheEleventhHour "The Eleventh Hour"]], Amy and Rory encounter a woman holding hands with two little girls. Although not twins, the girls look very similar and are dressed identically. The creepiness comes from the fact that [[spoiler:all three of them are actually a single alien "multiform", who gets confused and starts talking out of the wrong mouths with the wrong voices.]]
** Lampshaded in [[Recap/DoctorWhoS32E9NightTerrors "Night Terrors"]]. While searching an apartment building for a "scared kid", Amy encounters a pair of twin girls. She later asks the Doctor "I found ''scary'' kids, does that count?"
** The Time Trips novella ''The Death Pit'' features a couple of overly intimate (male and female) twins who speak in AntiquatedLinguistics who somewhat creep out the book's temporary companion, Bryony -- even though she's unaware that their growing up exposed to a powerful field of psychic energy has led to them developing RealityWarper-level PsychicPowers. Once the Doctor helps slay the psychic monster responsible for it, they immediately snap back into being normal, non-creepy twins.
* The Salamanca Twins in ''Series/BreakingBad''.
* A different take in Season 2 of ''Series/{{Luther}}''. The police catch a man committing random acts of violence at the throw of a dice. [[CliffHanger At the end of the episode]] another man wearing a hoodie sets out the same dice and murder implements; the camera then shows his face, revealing him to be an identical twin of the man in lockup.
* Mark and Luke from the second season of ''Series/TheFollowing''.
[[/folder]]

[[folder:Photography]]
* Creator/DianeArbus made her most famous photograph of two identical twin girls who stare directly into the camera. One of them has a slight smile, the other a slight frown. This haunting image is so famous that it's presumably Creator/StanleyKubrick 's inspiration for the twins' scene in Film/TheShining.
[[/folder]]

[[folder:Tabletop Games]]
* ''TabletopGame/{{Warhammer 40000}}'' fluff has the Apex Twins ([[Music/AphexTwin nyuck]] [[PunnyName nyuck]]): two adorable-looking girls who just happen to be out-and-out psychopaths. [[WithGreatPowerComesGreatInsanity They're also the most powerful psykers in the universe save perhaps the Emperor and Primarchs]].
[[/folder]]

[[folder:Video Games]]
* Zorn and Thorn from ''Videogame/FinalFantasyIX'' are [[TheScrappy extremely annoying]] examples of this trope, as they are nearly identical in appearance (with the exception of their colors) and constantly repeat what the other twin says (only in reverse with the case of Thorn). It turns out though that [[spoiler: they aren't twins at all, but are really one [[GrotesqueGallery grotesque and horrific]] monster that somehow poses as Creepy Twins.]]
* Alexia and Alfred Ashford in ''VideoGame/ResidentEvilCodeVeronica'', who are seen at one point in a home video [[spoiler: tearing the wings off a dragonfly and feeding it to ants.]] Let's not also forget that Alfred [[spoiler: misses his sister so bad from her being in cryo freeze that he dresses up as her, and honestly believes he IS her, until he's caught half-way between identities and looks in the mirror. Think less WholesomeCrossdresser, more ''Film/{{Psycho}}]]''
* Any of the Twins enemies in ''{{Persona3}}''. It's that rattling sound they make, and the fact that they're skewered together.
* ''FatalFrame 2''. That is all.
* ''ValkyrieProfileCovenantOfThePlume'' has Mireille and Mischka, a pair of twins who enjoy slaughtering people, are part of a mercenary group and display very good fighting skill despite being only twelve.
* ''{{Kuon}}''... '''oh God''' ''{{Kuon}}''.
* The Twin monster from ''SilentHill4''.
* ''VideoGame/PokemonBlackAndWhite'' gave us the Subway Bosses, Ingo and Emmet (Nobori and Kudari). Yet they are somehow very adorable, along with being creepy...
** {{Fanon}} obviously amps up their creepiness, ''specially'' via making them also {{Yandere}}s or {{Cute Psycho}}s.
* Jaryn and Kerith, the Glitterati twins from ''[[DanceCentral Dance Central 2]]''.
* The twins Martha and Lindsay from ''{{Catherine}}'', with their odd speech and unsettling amount of knowledge about the nightmares. In a variation for the trope they're old ladies.
* Strange and True, the conjoined "Amazing Twins!", from ''VideoGame/NightmareNed'' bicker more act like each other, but they're still pretty damn creepy.
* The VisualNovel ''MidoriNoUmi'' has Sorane and Rikuno, an unsettling pair who are almost completely indistinguishable from each other, aside from a few minor features like [[{{Tareme}} their]] [[{{Tsurime}} eyes]], are heavily into tarot cards, and speak every single word of their dialogue in unison.
* Gwendolyn and Charlotte Somersett, imperiled twin girls from the ''[[VideoGame/MysteryCaseFiles Ravenhearst]]'' game series, are justifiably creepy, both because they're ghostly SingleMindedTwins, and because they spent most of their (brief) lives being browbeaten and terrorized by Charles Dalimar, who kidnapped them and their mother to be his ideal "family". Hearing them call the abductor who trapped their souls "Father" while speaking in synch with one another could creep anyone out.
* ''VideoGame/TheCave'' has a set of twins as a playable character; and boy are they creepy constantly holding hands doing everything together, evil red eyes and [[ArsonMurderAndJaywalking extremely dated fashion sense]]. [[spoiler: Turns out they're Victorian twins that belong to a loving caring family but because said parents won't let them leave the house right away, they go to great lengths to kill their parents...and dogs...and ponies!]]
* Rosalind and Robert Lutece from ''Videogame/BioshockInfinite''. [[spoiler:They're actually parallel universe versions of the same person]].
* Some people feel [[AnimalCrossing Timmy and Tommy]] fit this trope pretty well, what with the fact that they're always staring at you. Sure, Nook does too, but he's shown more than a neutral expression. (This is ignoring the fact that they help run the shop and are probably just making sure you have the service you need.)
* Hisui and Kohaku from ''VisualNovel/{{Tsukihime}}''. Though they are faithful maids of the main character, it's as if they were hiding something...
** [[spoiler: Only Kohaku fits here: [[StepfordSmiler contrary to her cheerful demenor is in fact almost completely emotionally dead]] due to being [[BreakTheCutie repeatedly]] [[DespairEventHorizon raped]] by Makihisa Tohno and later SHIKI Tohno since she was 8 years old, something that caused her to hold a twisted need to destroy the entire Tohno family. Despite her stiff behavior, Hisui is honest to a fault and completely loyal to Shiki; not to mention, she actually has suffered quite a bit due to all the horrible crap that her twin sister had to go through to protect her from Makihisa's rape.]]
*** [[spoiler: Kohaku doesn't even want too--she doesn't ''want'' anything. It's just that she literally has no other reason to live apart from killing the Tohno, even if she is fond of Akiha (or as fond as she's capable of being). And then kill herself. She is so absent of personal motivation that she doesn't acknowledge pain or injuries.]]
* Danny and Demi from VideoGame/TheOutfoxies were former ConjonedTwins that had to be separated after a train crash. While they now have individual bodies now, they act as hitmen, going as far as have one of the kids hold the gun while the other fires it. [[spoiler:The ending even has them burning a man alive at an amusement park with smiles on their faces.]]
* Andariel the Maiden of Anguish and Duriel the Lord of Pain from ''VideoGame/DiabloII''. Not only they're evil as FUCK, but they're also powerful demons. Andariel is the DiscOneFinalBoss, and Duriel is ThatOneBoss.

* In {{Vocaloid}}, we have a few instances where twins Rin and Len Kagamine follow this trope to a T. Especially in [[http://www.youtube.com/watch?v=LmMKMn9jL3o Trick or Treat]] where they [[spoiler: trick Miku to play with them and eventually eat her.]]
* In the video for ''Oomph!'''s ''"Augen Auf"'' (Hide and Seek), the group of [[EnfantTerrible Enfant Terribles]] includes two identical twin girls who are perfectly syncronized.
* EvelynEvelyn aren't evil, but their songs, particularly the dual CreepyMonotone in "The Tragic Events of September", are pretty scary.
* The Mavericks' music video "[[http://www.youtube.com/watch?v=x-ujUhDGAeM Here Comes the Rain]]".
* The Music/{{Gorillaz}} music video for "[[http://www.youtube.com/watch?v=lRlmM88zzbY&feature=channel_video_title Rock the House]]" contains a pair in the beginning.
* The ghosts of Bonnie St Johnstone's children in the MurderBallad which bears her name. "Mother, when we were thine / Around our necks you pulled the twine ..."

* The Unity from ''TerrorIsland'' are three pieces (red, blue, and yellow) from the same game, and speak in [[http://www.terrorisland.net/strips/164.html riddles]], [[http://terrorisland.net/strips/076.html unison]], or [[http://terrorisland.net/strips/049.html both]], depending on what the authors feel like doing.
* The Viper twins in ''TheBeastLegion'' are a duo that are both creepy as well as ruthless & it can be clearly seen on [[http://www.thebeastlegion.com/issue-02-page-03wrath-of-the-viper-twins/ this page]]
* [[http://www.ddtcomic.com/2012/03/13/margaret-and-madeline/ This]] ''Dewey Defeats Tarzan'' strip features twin girls who are creepy even to their mother, and a reference to ''The Shining''.
* [[AllThereInTheManual Gwen and Leisel]] from ''Webcomic/CampWeedonwantcha'' claim to resent being called weird, [[IResembleThatRemark right before they start speaking in zodiac symbols]].

[[folder:Web Original]]
* thingOne and thingTwo from ''FanFic/TheMotleyTwo'' don't really embody this trope (they finish each other's sentences, but it's annoying rather than creepy), but when they face Tetras, against whom they hold a grudge, they decide to {{invoke}} this trope [[http://nixshadow.com/mspfa/?s=205&p=343 for sake of creeping her out]].
* Sokara and Setesh Vu Noi in ''TheGunganCouncil'' are ''insanely'' creepy in the way their minds are linked.
* A common ''GravityFalls'' AU called "Reverse Pines" turns the decidedly non-creepy Mabel and Dipper into this.
* [[SCPFoundation SCP]]-[[http://www.scp-wiki.net/scp-284 284]], two twins that literally ''share the same brain''.

[[folder:Western Animation]]
* The relentlessly bizarre BlackComedy ''Series/WonderShowzen'' has a pair of characters literally called the Creepy Twins.
* A creepy parody: "The Delightful Children from Down the Lane" in ''WesternAnimation/CodenameKidsNextDoor'' are not identical, and there are five of them, but their manner of speech and behavior are dead on for this trope. One episode also featured their cousins, The Interesting Twins From Beneath The Mountain.
* Sherri and Terri, the purple-haired twins of ''WesternAnimation/TheSimpsons'' fame, have only occasional creepy moments.
* In ''WesternAnimation/AvatarTheLastAirbender'', Princess Azula's teachers Lo and Li are of the rare elderly variety. [[spoiler:[[IWasQuiteALooker They were once quite beautiful, though.]]]]
** They spent the large part of the BeachEpisode trying to subvert this by showing they're not always "on", but just end up all the creepier when they [[FlungClothing fling off their regular clothes]] to show their ''swim suits''. Zuko was about to [[FanDisservice throw up]].
** They're also "off" in the final episode, [[spoiler:when they're subjected to Azula's paranoia.]]
* ''Avatar'''s SequelSeries ''WesternAnimation/TheLegendOfKorra'' gives us Korra's teenage cousins, HalfIdenticalTwins Desna and Eska. They both speak in [[CreepyMonotone Creepy Monotones]], wear blank expressions to rival [[EmotionlessGirl Mai's]], and are said to finish each others sentences. Additionally, Eska appears to have some unsettling {{Yandere}} tendencies.
--> '''Eska:''' You amuse me. I will make you mine.
--> '''Bolin:''' You mean like a boyfriend, or like a slave?
--> '''Eska:''' [[MathematiciansAnswer Yes.]] ''(Grabs Bolin by the collar.)'' Win me prizes.
** Their second appearance features them laughing, several seconds after rationalizing that something was funny. It wasn't actually funny, and [[MirthlessLaughter neither were they]]. No wonder Bolin was too scared to be on the run...
* ''Film/TheShining'''s twins make an appearance in an episode of ''FamilyGuy'' -- and are promptly blown up by [[EnfanteTerrible Stewie]] with a missile launcher.
* The unoriginally-named Cobra operatives Xamot and Tomax from ''{{GI Joe}}'', though, admittedly, originally these weren't meant to be their actual names.
** They're even creepier in ''GIJoeRenegades'' where they are depicted as {{cult}} leaders who brainwash their followers.
* ''WesternAnimation/{{Superjail}}'' has The Twins, who would've been creepy even if there had only been one of them.
* The 1977 children's film, ''RaggedyAnnAndAndyAMusicalAdventure'' features a wide variety of bizarre and deranged characters. Among the most [[TheScrappy aggravating]] are a naked pair of dolls that constantly spew [[BigLippedAlligatorMoment over the top]] and [[ThatRemindsMeOfASong irrelevant]] musical numbers while making [[UncannyValley unsettling]] faces. While they're probably meant to be cute and entertaining, they end up becoming profoundly disturbing.
* Jana and Jason are the villains of ''TenkoAndTheGuardiansOfTheMagic'' who turn into a [[ScaledUp big snake]] when combining their gems.
* Más y Menos from the TV adaptation of ''WesternAnimation/TeenTitans''. They're actually good guys, but when Brother Blood had them under mind control, they definitely fit this trope.
* ''InvasionAmerica'' has Simon and Sonia, a pair of genetically-engineered HalfHumanHybrid assassins, complete with psychic link. What made them creepy [[spoiler: before Sonia's HeelFaceTurn]] was that half the time, they didn't even speak to each other. They just shared looks, and you could tell by their expressions that they were communicating through thought. Simon, definitely the scarier of the two, also had a habit of torturing Sonia through their link as well.
* The Dee Dees in ''WesternAnimation/BatmanBeyondReturnOfTheJoker'' are pretty creepy with their evil Raggedy Ann looks complete with manic Joker-grins most of the time.
