The Rei Ayanami Expy is a character archetype common in JapaneseMedia, [[TropeMaker started]], or at least [[TropeCodifier codified]], by Rei Ayanami from ''Anime/NeonGenesisEvangelion''.

Common characteristics of the archetype include:
* LoveInterest (usually female).
* [[MysteriousWaif Mysterious and/or otherworldly]] origins.
* DarkAndTroubledPast
* [[TeenageTropes Age 10-20]].
* Pale skin.
* Short, usually bobbed hair.
* [[YouGottaHaveBlueHair Unnatural hair color]], often in cold tones like [[ShyBlueHairedGirl blue]], [[MysticalWhiteHair silver, grey or white]] (also occasionally pink).
* [[TechnicolorEyes Unnatural eye color]], often [[RedEyesTakeWarning red]], [[IcyBlueEyes blue]], [[SupernaturalGoldEyes yellow]], or even {{purple|Eyes}}, usually in a TsurimeEyes style.
* Appears [[EmotionlessGirl emotionless]], [[TheQuietOne quiet]], [[TheStoic stoic]], or otherwise [[NoSocialSkills odd]].
* A tendency towards talking in SpockSpeak, [[CreepyMonotone Mono]][[MachineMonotone tone]], RoboSpeak, or a combination thereof.
* Is {{not quite human}}, such as an ArtificialHuman, {{Transhuman}}, [[CloningBlues clone]], [[HumanAlien alien]] or [[RidiculouslyHumanRobot robot]], explaining their [[HughMann odd]] [[GlamourFailure behavior]].
* Suffers a major [[BandageBabe injury]] or [[IllGirl illness]], or at least is frequently hospitalized.
* Occasionally has a strong connection to a parental figure, boss and/or antagonist, and may even display UndyingLoyalty to them.
* [[DefrostingIceQueen Eventually becomes more emotional]], such as by [[BecomeARealBoy Becoming A Real Girl]] or turning out to have a SugarAndIcePersonality.

[[ShapedLikeItself Rei Ayanami herself exhibits every characteristic]], and [[FountainOfExpies many other characters]] have been created as variations on her. However, the [[FollowTheLeader popularity of this archetype]] has also led many of the variations to spawn {{Expies}} of their own.

A SubTrope of FountainOfExpies and ShyBlueHairedGirl. Compare to PhlebotinumGirl, CharClone and ShanaClone. See also {{Kuudere}}, EmotionlessGirl and StoicWoobie.


* Rei Ayanami from ''Anime/NeonGenesisEvangelion'', the TropeNamer, TropeMaker, and a {{Deconstruction}} of the archetype itself (making this an UnbuiltTrope). Rei is a seemingly {{emotionless|Girl}} [[TeenageTropes 14 year old]] girl with pale skin, [[ShyBlueHairedGirl blue hair]] and {{red eyes|TakeWarning}} who serves as one of the protagonist's LoveInterests; however, before he gets closer to her, she only relates to his father who also happens to be a weird and somewhat disturbing father figure for her. After being [[BandageBabe heavily injured during a battle]] at the start of the series, Rei slowly becomes [[DefrostingIceQueen more intimate with the protagonist]] as her [[NoSocialSkills stunted social skills]] improve. This eventually leads the main character to learn [[spoiler:[[CloningBlues Rei is one of multiple clones]] made to house the soul of an EldritchAbomination that's the [[MysteriousWaif key]] to a planned AssimilationPlot...and is also partially made from the DNA of his dead mother.]]

[[folder: Anime & Manga]]
* ''Anime/DotHackSign'':
** Subaru. She has short, bright blue hair, brown eyes (close enough to red), is quiet and very soft spoken as well as showing signs of being shy in RL. Also In real life, she is in a wheel chair from a terrible accident she keeps secret, and is a {{Meganekko}}. The series shared a character designer with ''Evangelion'', so it's plausible it was a deliberate reference between the two characters.
** Tsukasa shows traits of this, as well, mostly being emotionless (though it's more an angry sort of apathy).
* Kanade "Angel" Tachibana from ''Anime/AngelBeats''. She's presumed to be an angel working under God to oversee the afterlife. She's also seemingly emotionless, to the point where the other characters weren't even sure if she was sentient at first. [[spoiler: She's actually a human just like the rest of them. Her powers come from a computer program, and she seems blank because she'd given up on forming attachments to anyone. She displays some subtle humanity when Otonashi is getting to know her, and by the finale she's dropped the facade entirely.]]
* Maia Tsukigane from ''Anime/AquarionLogos''. She's a stoic girl with short white hair and NoSocialSkills who was trained by the BigBad ever since childhood in order to be his perfect enforcer. She's sent as an undercover spy to keep an eye on the main character, eventually falling in love with him.
* Chirico Cuvie ''Anime/ArmoredTrooperVOTOMS''. He has the blue hair, IcyBlueEyes, cold, unemotional exterior, and [[spoiler:is a vessel for a Godlike being, which he ultimately destroys or defies]]. Considering that ''VOTOMS'' came way before ''Evangelion'' in 1983, he could be regarded as [[OlderThanTheyThink the earliest example of this trope]].
* ''Manga/AttackOnTitan'':
** Mikasa Ackerman [[PlayingWithATrope plays with her status as one]]. She fills some qualities of a Rei Ayanami expy quite well (fairly emotionless, dark and troubled past, short cut hair, teenager, named after IJN Dreadnought), [[DoubleSubvertedTrope double subverts others]] (her hair color, appearance and skin tone are all considered unique, but that's merely because she's the only asian woman alive, [[spoiler: which also gives her immunity to the Coordinate]]), [[DefiedTrope and defies others]] (is never injured thanks to her phenominal combat skills, is the lead protagonist's adopted sister [[spoiler: and had no idea that she was related to Kenny Ackerman]]). She's also definitely not emotionless, rather she doesn't express her feelings the same way other people do and she can perform under pressure instead of panicking ([[spoiler:which is a common trait of the Ackerman family]]).
** Annie Leonhardt also plays with this. She has pale skin, IcyBlueEyes, and is even more emotionless and cold than Mikasa. [[spoiler: She also happens to be part of a group of titan shifters that have some kind of evil agenda in mind, and is revealed to be the deadly Female Titan, to everyone's great shock. She does end up showing emotion, but unlike other examples, it's disturbing rather than a good sign.]]
* Sen Yarizui, "the Ice Witch", from ''Anime/BenTo'', though she's more of a very laid-back {{Cloudcuckoolander}} as opposed to being shy and emotionally repressed.
* [[SpellMyNameWithAnS Ondine/Undine]] from ''Anime/BirdyTheMighty'', though she doesn't last long.
* Jo of ''Anime/BurstAngel''. Dead ringer, aside from a rougher appearance and personality and having a slight tan, making her a bit of a [[DevilMayCry Dante]] expy as well.. She's even referred to as an angel of death. Plus, they both pilot giant mechs. [[spoiler:And they are both {{Artificial Human}}s.]]
* ''Anime/CodeGeass'':
** Anya, a pink haired [[RedEyesTakeWarning red eyed]] 15 year old HumongousMecha pilot who [[TheQuietOne likes taking pictures of people more than talking to them]], [[spoiler:and is a SoulJar for the protagonist's mother]].
** C.C. also has a number of these traits as well, though she is a ''lot'' snarkier than most. Also Rei was not a Pizza fanatic.
* Tsubame Otorii from ''Anime/CyberTeamInAkihabara''. She's even being voiced by Music/MegumiHayashibara, Rei's seiyuu.
* Yin from ''Anime/DarkerThanBlack''. Her emotionless state is due to her being one of the setting's [[MeaningfulName Dolls]].
* Due to their awkward habits, stoic natures, pale skin, and lack of proper people skills, L and [[spoiler: his eventual successor]] Near from ''Manga/DeathNote'' are rare male examples. This probably goes even moreso to Near due to his hair color.
* ''Anime/DualParallelTroubleAdventure'' has the character D, who pretty much is a straight up {{expy}} of Rei (this show has been described as ''Evangelion'' [[JustForFun/XMeetsY meets]] ''Tenchi Muyo''), being a [[ArtificialHuman bio andriod]] who acts like a robotic EmotionlessGirl. She does however lack Rei's appearance, (which is probably because of legal issues).
* Ren from ''Manga/ElementalGelade'' (her name is even one letter apart from Rei) has waist length blue hair, green eyes and speaks in a monotone voice. Not only is she an Edel Raid ([[LivingWeapon girls who can bind their soul with their Pledger and turn into a weapon]]) but is a Shichiko-hoji, one of the most powerful Edel Raids. Of course this means that [[PhlebotinumGirl everyone wants their hands on her]]. In the beginning of the show she's an EmotionlessGirl who hates Coud because he's a human, but later [[DefrostingIceQueen starts developing feelings for him]] and they become a couple at the end.
* Lucy from ''Manga/ElfenLied'' could be considered an extremely ''dark'' take on the archetype. She has pale skin, unnatural hair and (in the anime) eye color, indeterminate origins, isn't entirely human, has a very cold demeanor (even after defrosting) unless she's killing someone, serves as a LoveInterest to the main male lead Kouta, and is [[UndyingLoyalty single-mindedly devoted]] to him. However, her single-minded devotion to Kouta has lead to deadly consequences for everyone involved. She also suffers a significant injury by getting shot in the head in the beginning, is the key to the {{Big Bad}}'s plans, and, closer to the original take, [[spoiler:serves as an ApocalypseMaiden in the climax]]. Will all of those facts, she's one of the few examples who actually stays true to the original character's UnbuiltTrope nature.
* Eureka from ''Anime/EurekaSeven''. Very light turquoise hair, a HumanAlien, very attached to her boss at first and is an IllGirl and EmotionlessGirl as a result of her upbringing, prior to a traumatic event that would trigger her CharacterDevelopment, which then was accelerated much further by meeting her LoveInterest. [[spoiler:Specifically, she was used by the government as a TykeBomb, and trained to kill almost remorselessly, until one day, when she was checking a pile of corpses looking for wounded people to finish off, she found three orphans, had a huge epiphany, and decided then and there to adopt them and defect from the military]]. Realistically enough, she could still slip back into emotionless behavior on occasion. [[EmotionalTorque The occasions presented themselves]].
* ''Manga/FairyTail'':
** Merudy, a young girl with short-cut pastel-coloured hair and a petite body, is very stoic and her voice in the anime is very soft. She even calmly starts to dispatch Erza and Juvia, claiming with a cold expression that it's her mission to do so. She's also fiercely devoted to her parental figure, Ultear, going as far as to wanting kill Gray, the person she hates for killing Ultear's mother. After the timeskip, her personality has completely changed and now is very cheerful.
** Yukino Aguria, a shy, obedient girl wih short silver/light blue hair.
* ''Manga/FutagoNoTeikoku'' has Fa. She has short, blueish hair, is very reserved and stoic, has a strong attachment to Gaw, and has a magical curse placed on her.
* Ledo from ''Anime/GargantiaOnTheVerdurousPlanet'', although a male example. White hair, pale skin, purple eyes, otherworldly origins, NoSocialSkills, stoic, and even a mecha pilot to boot.
* [[IdolSinger Inori]] [[MysteriousWaif Yuzuriha]] from ''Anime/GuiltyCrown'' shares many traits with Rei, in both personality and situation. [[TheStoic Stoic]], seemingly [[EmotionlessGirl emotionless]]? Check. Red eyes? Check. [[UndyingLoyalty Deeply devoted]] to her boss, and, later, the main character? Check. [[spoiler:ArtificialHuman based on one of the protagonist's family members who nevertheless has boatloads of {{UST}} with him? Um...check.]] The only way for Inori to be a more thorough example would be if she had blue hair instead of pink and piloted one of the show's mecha.
* ''Franchise/{{Gundam}}'' finally provides its first example with Mikazuki Augus from ''Anime/MobileSuitGundamIronBloodedOrphans'', the first in the ''Gundam'' franchise. He's emotionless, short in stature, has short hair, is a ChildSoldier, has significant injuries, NoSocialSkills, UndyingLoyalty to Orga, and to top it off, a mecha pilot. As an added bonus, his name means "Crescent Moon", which has connotations with the cold (like Yuki and Rei), and was an Imperial Japanese warship. Unlike other examples, though, he rarely becomes more humanly expressive, and this lack of development is played for drama.
%%* Kisaragi from ''Manga/HappyLesson''.
* Ikaros from ''Manga/HeavensLostProperty''. An emotionless, obedient and submissive Angeloid who comes to slowly warm up thanks to the main character.
* Kanna from ''Manga/{{Inuyasha}}'' by virtue of her white hair, pale skin, lack of emotions and the fact that she's an ArtificialHuman. She's also [[CreepyChild a little girl]].
* Shimei Ryomou of ''Manga/IkkiTousen'' (Battle Vixens). Complete with bandage over one eye.
* Sara from ''Anime/JewelpetTwinkle''. Blue hair, red eyes, pale skin, TheStoic with a SugarAndIcePersonality.
* Nozomu Ezomori in ''LightNovel/{{Kanokon}}.'' Not surprising, since she shares the same VA with QB's Aldra, except being more slutty.
%%* Anju Maaka from ''Manga/{{Karin}}''.
* Ayuki from ''Manga/KashimashiGirlMeetsGirl'' matches to a degree. She's a slender {{Meganekko}} with a bob. While not exactly stoic, she's quiet DeadpanSnarker who prefers science and learning over romance.
* ''Anime/KeyTheMetalIdol'' has one in the form of its titular protagonist, Tokiko "Key" Mima, a shy, emotionally constricted RidiculouslyHumanRobot prone to fits of otherwordly rage, who seeks to become human before her battery runs out. Considering that the work was made before ''Evangelion'' came out, she could be considered a [[OlderThanTheyThink proto-example of this]].
* Minami Iwasaki from ''Manga/LuckyStar'' is a parody of this.
* Fate from ''Manga/MahouSenseiNegima'' is a male example of the trope. White-haired, emotionless, ArtificialHuman created by the BigBad.
* Miyu ([[spoiler:or, more correctly, M.I.Y.U.]]), from both ''Anime/MaiHime'' and ''Anime/MaiOtome''.
* Ruri Hoshino of ''Anime/MartianSuccessorNadesico.'' Blue-grey hair, yellow eyes, odd origins, very stoic.
* The titular Anime/MissMonochrome. She is a white-haired, blue-eyed android aspiring to become an idol. She's pretty emotionless and so socially inept that her servant easily tricks her into giving her all her fortune and she can't tell the difference between a store manager and an idol manager.
* Mamiko Kuri from ''Manga/{{Narutaru}}''. A mysterious girl with pale skin and cold eyes whom Sudo took under his wing when he found out she had a shadow dragon. She tends to be rather quiet, and often considers the people around her to be inferior. It's later revealed that [[spoiler:Mamiko's shadow dragon is the earth itself and she is one of those who must judge this world and make the choice of what kind of world it will become. At the end of the manga, Mamiko destroys everyone and everything in the world except Shiina and herself. They begin the world over again, with Mamiko's son as the new Adam of the reborn world.]]
* Not the most obvious but Sai from ''Manga/{{Naruto}}'' has shades of being an expy of Rei. He's a pale teenager with NoSocialSkills and a MysteriousPast, and is TheStoic.
* Mai from ''Manga/{{Nichijou}}'' has demeanor but she's TheGadfly personified.
* Kirika Yuumura, from ''Anime/{{Noir}}'' is another brunette with similarities - Initially emotionless, although she does cry in episode one (although she's crying because she can't feel regret, not because of the dozen men she just killed), soft-spoken and created as a weapon. Her eyes are at the red end of brown, getting redder whenever there's an open fire around - used to great effect when her 'true self' comes out towards the end of the series. The series ends with her choosing between being human, or being a weapon.
* Lala Ru from ''Anime/NowAndThenHereAndThere''. A mysterious blue-haired, blue-eyed girl with special water powers who claims to be thousands of years old. Due to her long and disillusioned experience with humans, she feels little to no emotions with them. Her relationship with Shu changes her to be more protective and open.
* Echo from ''Manga/PandoraHearts''. She's a white-haired girl with a stoic personality who serves as the minion of the {{Yandere}} brother of one of the main characters. She also has a dangerous SplitPersonality named Noise. Eventually, the protagonist Oz befriends her and it's usually implied Echo might have feelings for him.
* Ein from ''Phantom'', including the haircut (but not the hair color.) She even winds up laying impassively under TheHero by the end of the first episode.
* Isla from ''Anime/PlasticMemories'' is a [[RidiculouslyHumanRobot Giftia]] with silver hair and red eyes. She is highly serious and emotionally distant, due to being a ShellShockedVeteran of a job that involves retrieving and terminating her own kind. Yet she's very {{Adorkable}} and eccentric. As the series progresses, she becomes more open thanks to her love interest. She is also in a decaying physical condition, since her 9-year lifespan is nearing its end.
* Mytho from ''Anime/PrincessTutu'' is a male example. He's a white-haired, magical prince from a fairy tale. The shards of his heart, his emotions, were shattered throughout the land. As a result, Mytho is an emotionless shell and Duck spends much of the first season working to restore his emotions.
* Aldra in ''Anime/QueensBlade'', but only in the original series, since in the sequel, her personality was [[ReTool retooled.]]
* Anthy from ''Anime/RevolutionaryGirlUtena'', right down to [[spoiler:being a goddess stabbed by the villains to contain her power (remember, Rei has Lilith's soul.)]] Given ''Utena's'' original air date, she's probably the UrExample, as wee as one of the few to stay true to Rei's UnbuiltTrope nature.
* Lan from ''Anime/RinneNoLagrange'' is a different take on the archetype. She has all of the characteristics that place her firmly in the category; [[YouGottaHaveBlueHair blue hair]], pale skin, PurpleEyes, TheStoic, [[NoSocialSkills strange behavior]], [[HumanAlien an alien]], and co-starring in a HumongousMecha series. She's different in that her stoicism doesn't work as well as she tries to and it soon becomes clear she's NotSoStoic. ''[[RunningGag Really]]'' NotSoStoic. She defrosts into more of an average emotional girl sooner than expected. Also, her odd greeting is the result of her being ''lied to'' about Earth culture.
* By [[Creator/NobuhiroWatsuki the mangaka's]] own admition; Tomoe Yukishiro from ''Manga/RurouniKenshin'' was designed after Rei. She may have dark hair, but personality-wise she fits surprisingly well: she's quiet, apparently cold yet kind-hearted, becomes Kenshin's love interest as she defrosts [[spoiler: and dies to protect him]]
* ''Anime/SaintSeiyaOmega'' has the tiny, quiet, blue-haired Aria. Demure and shy? Check. Blue hair and eyes? Check. MysteriousWaif with a DarkAndTroubledPast? Check. [[DefrostingIceQueen Learns to express her emotions better through contact with the main character]]? Check. Has great and mysterious powers? Check. [[spoiler: Not entirely of human origin?]] Check. [[spoiler: Gets killed off]]? Check...
%%* Mero Furuya from ''Manga/{{Sankarea}}''.
* A rare male expy in the anime adaptation of the yaoi manga ''Sensitive Pornograph'' as the ExtremeDoormat character Aki. He has her hair, dark reddish brown eyes and even has his arm and right eye bandaged similarly by the end of it.
* Lain from ''Anime/SerialExperimentsLain'' fits everything here, except she has brown hair. Notably, the creators of ''Lain'' [[WordOfGod have said]] they didn't even watch ''Evangelion'' until they finished the fourth episode of ''Lain''.
* Gowther from ''Manga/TheSevenDeadlySins'', also another male example but fits the bill perfectly. [[SupernaturalGoldEyes Golden eyes]], NoSocialSkills, completely {{emotionless|boy}}, [[PinocchioSyndrome wants to become more human-like]], and to top it off, [[LivingToys a doll]].
* In ''{{Anime/Shirobako}}'', [[ShowWithinAShow the fictional series being worked on]] ''3rd Aerial Girls' Squadron'' has one in the protagonist, Aria. Tragic past. EmotionlessGirl. Bob Haircut (in pink).
* Noël from ''Anime/SoundOfTheSky''. White-haired, pale skinned pilot and mechanic of the crew's SpiderTank that hardly speaks, when she does she uses a monotone and has a DarkAndTroubledPast coming back from when she was a ChildProdigy. More lively when drunk.
* Cheza from ''Manga/WolfsRain''. She looks like Rei Ayanami with pink hair. Being half-plant qualifies her as not fully human. She's also quite emotionless, although she does perk up quite a bit in the presence of wolves.
* ''Manga/TheWorldGodOnlyKnows'': Dokuro, the girl who Keima meets in his time travel [[spoiler:and the past self of his teacher Yuri Nikaido]], has many characteristics of this trope. She's a powerful ArtificialHuman [[spoiler:and some kind of clone of the original Dokuro Skull]], has bobbed hair and PurpleEyes. When she's introduced, she's an EmotionlessGirl, but thanks to the main character she warms up and becomes very upbeat.

[[folder:Comic Books]]
* The ''Manga/MarvelMangaverse'' version of ''Comicbook/FantasticFour'' is, depending how you look at it, either a FusionFic or extended ShoutOut to ''Evangelion''. Each member of the team was heavily {{Revision}}ed to resemble a member of the ''Evangelion'' cast, with Sue Storm/The Invisible Woman ([[AdaptationNameChange renamed "Sioux Storm"]]) acting as the Four's cold, distant Rei equivalent.

[[folder:Fan Works]]
* Krieger Female Model 68b #6345 from ''Fanfic/LoveAndKrieg''. She is an emotionless, highly indoctrinated cloned soldier (with short hair, although it's blond), and she does rarely enough express emotions, like affection towards her normal civilian boyfriend. It's surprisingly cute.
* Tsukuyomi from ''Fanfic/{{Infinity}}''. [[RidiculouslyHumanRobot Artificial]], [[TheStoic stoic]], [[TheSpock keeps her emotions suppressed]], exceedingly polite, intelligent and deadpan {{Cloudcuckoolander}} whose honesty extends to discussing her tactics with her enemies and openly [[MoreExpendableThanYou considering herself expendable]]. Like the rest of her siblings, [[YouGottaHaveBlueHair she also has blue hair]].
* Chronicler from ''Fanfic/CitadelOfTheHeart'' is a rare male example of this trope. [[NoSocialSkills Lack of knowledge of the social norm]], [[YouGottaHaveBlueHair bluish black hair]], [[TechnicolorEyes eyes with silver pupils and red irises]], [[MysteriousPast generally mysterious with an other-worldly origin]], 18 years old at the time of his official introduction, pale skin, [[DarkAndTroubledPast an entire past of being abused by those who had some degree of power and or authority over him]], he's a HalfHumanHybrid so he's definitely NotQuiteHuman, and he's also a LoveInterest for [[LightNovel/SwordArtOnline Suguha]].

* ''Film/PacificRim'' gives us Mako Mori. While being older, having a rather more well-adjusted and sociable personality and there's nothing artificial about her origin, she's the only Japanese character in the film, is [[TheStoic stoic and reserved]], fiercely loyal to her adoptive father figure, and sports Rei's haircut as said above. It's even colored blue, though only at the tips. She also happens to be a HumongousMecha pilot. Popular fan consensus is that it's supposed to say, "We took -some- inspiration from Evangelion but didn't try to ape it".
** Explicitly invoked in the Japanese dub. Instead of having Creator/RinkoKikuchi dub her own lines over in Japanese (which she would be perfectly capable of doing), Mako is voiced by the same person responsible for Rei - Music/MegumiHayashibara. You can't get to be a bigger Expy than that!

[[folder:Light Novels]]
* Julie Sigtuna from ''LightNovel/AbsoluteDuo''. Silvery-white hair, red eyes, pale skin, petite, mysterious and troubled past, not a normal human, stoic and weird behaviour, eventually reveals a sweet and emotional side to her love interest.
* Isuzu Sento from ''LightNovel/AmagiBrilliantPark'', with her upbringing as a soldier leaving her stunted in the social department, unemotive demeanor, otherworldy origins, and not being entirely human, as well as being the love interest to the main character. The only thing that separates her from the other examples is that she's taller than average, has long hair, normal hair, eye and skin color, and is [[GagBoobs quite endowed]].
* Mei Misaki, from the ''Literature/{{Another}}'' horror/mystery light-novel series most certainly qualifies. An EeriePaleSkinnedBrunette with emphasis on [[TownWithADarkSecret eerie]], dark short hair, skin so pale it is in a shade of grey, [[RedEyesTakeWarning red eyes]], an eye-patch resembling Rei's usual bandages, [[EmotionlessGirl a deeply stoic demeanor]] and the overall feeling of creepy cuteness/cute creepiness exhaled. Visually, she is basically Rei with pitch black hair.
* Felli Loss from ''LightNovel/ChromeShelledRegios'' is a silver-haired psychokinetic whose powers make her unable to express emotions the same way as others, but is slowly warming up to the protagonist. She's also a rare example of this character type mixed with ShanaClone.
* Origami Tobiichi in ''LightNovel/DateALive''. She even has the ChildSoldier who drives Mecha vs PersonOfMassDestruction thing going. She's also a StalkerWithACrush and one of the few characters listed who is a bit of a jerk.
* Sf from ''LightNovel/TheEndingChronicle''. A silver-haired automaton created using technology from another world. She's the personal maid of the supervisor of Team Leviathan. She lacks emotions, but shows an extreme amount of loyalty and devotion for her master.
* Tabitha from ''LightNovel/TheFamiliarOfZero''. Bobbed light blue hair, very fair skin, quiet and deeply stoic demeanor, and speaks in strangely truncated, sentences with barely enough to get her point across, often single-word ones.
* Lelei La Lalena from ''Literature/{{Gate}}''. A 15-year-old genius sorceress with short light blue hair and eyes. She's stoic and quiet, but a nice girl. She also forms part of the UnwantedHarem of the main character.
* Yuki Nagato from ''LightNovel/HaruhiSuzumiya'', to the point where her name is a pun on Rei's--Rei can be read as "ice", Yuki as "snow", and both Nagato and Ayanami were Imperial Japanese naval warships. Curiously, Yuki is described in the novels as having black hair (since in the Haruhi universe people have normal hair colors) but in the anime and even in the novels' art, it appears of a purplish blue similar to Rei's (but much more pale). Her characterization, however, has some variance: She is a LoveInterest only briefly, if that (though she is one in the spin-off where she's a normal human ShrinkingViolet); she neither is a MysteriousWaif nor does she have a DarkAndTroubledPast (if anything, she becomes more interesting the more we know her); and the becoming more emotional part is downplayed, in that her affect remains as flat as ever, but she seems to undergo significant CharacterDevelopment and emotional development under the surface (despite the fact she states her affect will always be flat, she nevertheless seems to become more expressive and animate in her own way as the series progresses).
* Koneko from ''LightNovel/HighSchoolDXD''. Pale skin, short silver hair, golden eyes, petite, is not human, appears cold and soft-spoken and eventually warms up to the main character.
* In ''LightNovel/HorizonInTheMiddleOfNowhere'', there's an amnesiac, emotionless [[RobotGirl automaton]] with silver hair and blue eyes known as P-01s. It's later revealed that she's Horizon Ariadust, a human girl who died in an accident years ago. After her death, her father put her soul in an android body and used her emotions to create WeaponsOfMassDestruction that will give her the power to save the world from an apocalypse. Horizon also serves as the love interest of the main character Toori Aoi.
* ''LightNovel/InfiniteStratos'':
** Laura Bodewig. A white haired, a red eyed and yellow eyed, genetically-engineered ArtificialHuman [[TykeBomb raised as a]] SuperSoldier, and educated with just enough social skills to be able to function as a soldier, which left her with no idea of how to act like a normal girl and socialize normally. Initially, she hates the main character, but she later falls in love with him and chooses him as her "wife". She's also another example of this mixed in with ShanaClone as she's got the long hair, short stature and temper.
** Kanzashi Sarashiki. Red eyes, short aquamarine hair, shy and quiet personality, eventually warms up to the main character and falls in love with him.
* Eucliwood Hellscythe from ''LightNovel/IsThisAZombie''. Light hair, pale skin, mysterious abilities and origins and a deeply quiet and stoic demeanor that makes her come across as emotionless, but still has a hidden caring side.
* Nozomi from ''LightNovel/MayoiNekoOverrun''. A mysterious girl with blue hair and red eyes. She normally tends to be indifferent and emotionless, and also seems to be a little airheaded.
* Shiro from ''LightNovel/NoGameNoLife''. A young girl with light blue hair and red eyes. She's a {{Hikikomori}} {{Neet}}, bue she's actually a genius with an almost supernatural intelligence. She also only shows emotion around her older brother Sora.
* Hazuki from ''LightNovel/NogizakaHarukaNoHimitsu'', though she doesn't have any dramatic plotline related to it, she is just weird.
* Mashiro from ''LightNovel/ThePetGirlOfSakurasou'' is an odd girl, with virtually NoSocialSkills, [[EmotionlessGirl doesn't understand the concept of emotions too well]] and has very light blond hair, a really fair skin and reddish eyes. Although, her behaviour is usually taken to be the effect of an AmbiguousDisorder.
* Fremy Speeddraw from ''LightNovel/RokkaBravesOfTheSixFlowers''. A stoic, cold young girl with white hair, pale skin, blue eyes and an eyepatch. Fremy is the first and only half human/half kyouma in the world and she was once the Six Flower Killer, an assassin who killed potential future heroes of the Six Flowers. She was chosen as a Brave after she was betrayed by the Kyouma who raised her, her own mother among them. At first, she doesn't want to trust anyone ever again, but Adlet gains her trust and she falls in love with him.
* Hecate from ''LightNovel/ShakuganNoShana''. "The Priestess" of Bal Masqué, she has the appearance of a small blue-haired girl with blue eyes. A quiet and emotionless character.
* Shino Asada[=/=]Sinon from ''LightNovel/SwordArtOnline''. She has short hair, fair skin, a DarkAndTroubledPast, and an emotionally-distant demeanor that defrosts thanks to the main character. Her MMORPG counterpart Sinon even has the blue hair and eyes to go with it.

[[folder:Video Games]]
* Creator/{{Atlus}} LOVES Evangelion, so within many Evangelion references in their games, of course there's several Rei Ayanami Expies. So far, there's five of them. That's already more than half of the number of Rei expies used to create the page image. [[SarcasmMode Maybe the day where we can make the page image using Rei expies from Atlus only will come. Maybe.]]
** Gender flipped with Serph from ''VideoGame/DigitalDevilSaga'': an initially [[DefrostingIceQueen completely emotionless]] pale-skinned gray-haired [[HeroicMime almost totally silent]] [[InvertedTrope male lead]] who's [[spoiler: [[ArtificialHuman a digital clone]] of [[CloningBlues a sociopath scientist who nearly destroyed the entire world]]]], and is completely devoted to [[InvertedTrope female love-interest]] [[MysteriousWaif Sera.]]
** ''VideoGame/DevilSurvivor'''s Amane Kuzuryu, a blue haired, blue eyed EmotionlessGirl [[spoiler:that serves as the host to both an angel ''and'' a demon.]] In [[MultipleEndings her route]], she reveals the reason for her behavior and wishes that she had been able to lead a more normal life.
** In ''VideoGame/Persona3'', we have two! First is the Protagonist himself, who possesses blue hair and eyes that are either blue or silverish, and also appears emotionless but gradually becomes more human as he forms bonds. (His characterization in the first animated movie adaption mirrors Rei's in the first Rebuild movie, complete with a WhenSheSmiles moment!) Second is Aigis, with her robotic nature and exotic looks, but isn't quite as emotionless so much as initially single-minded. Her role only settles in when Ryoji, the Kaworu Expy, enters the story and she immediately becomes suspicious of him.
** ''VideoGame/DevilSurvivor2'' has Miyako. She just appeared in Record Breaker, but it's no doubt that Miyako is a Rei expy too. She has short hair and eyes in color shade similar to Rei's hair. Okay, initially she is not that emotionless, but she does [[DefrostingIceQueen eventually become more emotional]], later becomes one of the protagonists' main love interest, [[spoiler: isn't exactly human. Rei is the soul vessel for Lilith and Yui clone, when Miyako is the mix of Fourth Triangulum and Yamato clone, later fight against her own kin other than human.]]. Also, she is noticeably less polite and wary of Alcor, the Kaworu expy in said game.
* Mari Ming Onette from GrandChase can be called one.
* Lydia from ''VideoGame/ChroniclesOfInotiaChildrenOfCarnia''.
* Sybill from ''VideoGame/{{Alundra}}''.
* The Character Kos Mos in the VideoGame/{{Xenosaga}} Series is a female [[YouGottaHaveBlueHair blue haired]], red eyed [[EmotionlessGirl Emotionless]] Robot which becomes more humane/defrosting. [[spoiler:Like Rei, she and her successor Model "T-Elos" have got something to do with the plan of the antagonist/government organisation.]]
* ''VideoGame/FireEmblemElibe'':
** Tate from ''Fire Emblem 6 (Binding Blade)''. She looks the part and has the SugarAndIcePersonality down pat.
** The dancer Ninian from ''Fire Emblem 7 (Blazing Sword)''. Though she lacks the short hair, it IS blue, and she has red eyes, an unusual color even for FE standards, as well as pale skin, and is pretty frail both in cutscenes and in combat. She's also notably shy and reserved but can open up to all 3 of her support options (one of which is a possible love interest), and hides a dark secret; [[spoiler:she's a dragon born from a human father. Her tragic family history is revealed in Hector's story, in which the player learns that her father is the main antagonist, Nergal, who sent her and her brother through the Dragon's Gate for their own protection during the Scouring, a massive human/dragon war. Their mother, Aenir, was killed, and Nergal, seeking to reunite with his children after the war was over, began experimenting with unscrupulous dark magic that warped his mind and made him forget his original purpose. Centuries later, in an ironic twist of fate, he manages to call his children back through the Gate, but they don't remember him, and he doesn't remember he had children in the first place, only wanting to use the siblings to further his own goals of obtaining power.]] Worst of all, [[spoiler:he actually laughs when Eliwood accidentally kills her.]]
* Vanilla H from ''VideoGame/GalaxyAngel'', a red-eyed, pale-skinned young girl who controls nanomachines by suppressing her emotions.
* Leen from ''VideoGame/{{Grandia}}'' has almost every trait of it, and is maybe the first one.
* Angel of ''VideoGame/OneMustFall 2097'' fits the trope to a T.
** She also happens to predate Rei by a year. One Must Fall came out in 1994. Evangelion first aired in 1995.
* Blaze the Cat of ''Franchise/SonicTheHedgehog'' fame is a sort of anthropomorphic interpretation of this type of character, down to the same general color scheme and hairdo. Because her role as the dedicated guardian of the Sol Emeralds is of tantamount importance in her dimension, she initially distrusts strong emotions and social attachments, which she sees as distractions. She later embraces both to a degree.
* Stern the Destructor of the ''VideoGame/MagicalGirlLyricalNanohaAsPortable'' games. She's an ancient, alien, {{Magitek}} program that copied Nanoha's appearance, with a few changes such as her hair being cropped short and her eyes being an unnaturally light color of blue. As the Material of Wisdom, she has little to no emotions and is completely logical. However, she starts gaining some emotions after she met and [[DefeatMeansFriendship lost to]] Nanoha, even gaining her own personal desire to improve herself in the hopes of [[TheRival one day beating Nanoha]] in a LightheartedRematch.
* [[Franchise/{{Metroid}} Samus Aran]] became this trope in ''Videogame/MetroidOtherM'', with characteristics from both Rei and Shinji. She speaks in a stoic monotone, seems to suffer from low self-esteem like Shinji, and lots of emphasis is placed on her loyalty to Adam (much like Rei's loyalty to Gendo) and her DarkAndTroubledPast, both of which are the cause of most of her [[NotSoStoic emotional breakdowns]] throughout the game (such emotional breakdowns were a staple of ''Evangelion''). A flashback scene even gives her a bobbed haircut similar to Rei's.
* Shiki from the ''VideoGame/SamuraiShodown 64'' series is older than the average, but otherwise fits the bill nicely (the whole TechnicolorEyes thing being derived from DemonicPossession, but she has heterochromia meaning she's not ''completely'' being controlled).
* The Kritya from ''VideoGame/TalesOfVesperia'' are an entire ''race'' of strange, blue-haired nonhumans who... [[EmotionlessGirl don't quite]] [[CloudCuckooLander have it all together]]. The party's [[TheBigGirl Big Girl]], Judith, is considered weird by their standards for being a [[TheTease flirtatious]] BloodKnight who will offer to show off [[MsFanservice even]] ''[[MsFanservice more]]'' [[MsFanservice skin]] [[{{Stripperiffic}} than she usually does]] and devise battle strategies that involve ''being eaten alive by monsters and then ripping them open from the inside'' in the same emotionless tone of voice that everyone on this page has.
* ''VideoGame/{{Touhou}}'' has Hata no Kokoro, a pink-haired [[AnimateInanimateObject tsukumogami]] based on a set of 66 noh theater masks with a close connection to an antagonist from the previous game in the series. Kokoro is simultaneously a LargeHam, MoodSwinger and EmotionlessGirl, "[[BossSubtitles The Expressive Poker Face]]" who expresses herself through her {{Floating Mask}}s, but after some character development she learns to handle and display her feelings more naturally.
* The New Angelic Gaia Interface from the eroge game ''Makai Tenshi Djibril'' is a wholesale expy of Rei Ayanami, from the fact she's got blue hair and pale features, she's also a artificial angel, of the holy kind, whose whole purpose is to go into battle and get maimed, and she does in fact shrug off a lost arm at least once.
** Also, the mark of a transformed Devil Angel when working for Heaven was, for the first three games, that their hair took on a pale color, as close to light blue as possible.
* Melphonshina from ''VideoGame/PhantasyStarOnline2'' more or less falls straight into this trope, minus being a LoveInterest. Her DarkAndTroubledPast being that [[spoiler: she was envious of the relationship between [[BloodKnight Gettemhult]] and his partner, and wished to be in her place]]. After she's [[spoiler: used by Gettemhult to release [[EldritchAbomination Dark Falz Elder]]]], she gets seriously injured. [[spoiler:After Dark Falz Elder [[HeroicSacrifice sacrifices himself]] two Episodes later,]] she breaks out of this to a degree.
* Courtney from ''[[VideoGame/PokemonRubyAndSapphire Pokémon Ruby]]'' is [[PlayedWith re-imagined along those lines]] in the remake, ''Omega Ruby'', with robotic [[TerseTalker mostly short]] speech patterns, (though she does speak full sentences at certain points, though with Creator/WilliamShatner levels of pauses) [[CurtainsMatchTheWindow violet hair and eyes]]. Ironically, different traits, such as short hair and an attraction to a protagonist are only apparent in the Ruby and Sapphire chapters of ''Manga/PokemonSpecial'' which is based on the original games and thus is not an EmotionlessGirl there (or in the original games for that matter). In both cases she does have a connection to the antagonist, being a member of Team Magma and one of its CoDragons.
* ''{{VideoGame/Blazblue}}'' has the Murakumo Units, a series of {{Magitek}} cyborgs. There are three playable Murakumos and each of them have some of Rei's traits. As a whole, Murakumos are young women with light hair and skin, draw power from an EldritchLocation, were created by an abusive MadScientist father, are varying flavors of TheWoobie and are clones of Ragna's (the protagonist) long lost sister. Lambda-11 is curious, innocent, developing emotions, has red eyes and is forced into battle by her boss and sort of mother figure Kokonoe because there's just no other choice. Noel, aka Mu-12, didn't know she was a Murakumo for years and developed a proper (but meek) personality, initially serving the local StateSec to support her family but eventually breaking away from that to help save the world. Nu-13 has red eyes, silvery blue hair and pale skin and seems to be an IllGirl, and switches from being utterly emotionless to the definition of {{Yandere}} whenever Ragna shows up.
** Their genetic template, Saya, was pretty similar to Noel before becoming the Imperator [[spoiler:and being made a vessel for Izanami, the Goddess of Death.]] When Ragna meets an adult Saya for the first time, her appearance and personality took a huge change. She is absolutely devoid of emotion, ruthless, nihilistic and hateful towards the world. Her golden locks have become purple, and her previously jade eyes are now crimson. [[spoiler:All of this can be attributed to her being possessed by Izanami, and Saya's consciousness apparently struggles for control, resulting in the Imperator showing some sympathy towards Ragna and despising Terumi.]]
* Ramlethal Valentine from ''VideoGame/GuiltyGear'', albeit a DarkSkinnedBlonde case[[note]]Though her dark skin could be [[HadesShaded the result of originating from the Backyard]][[/note]], but otherwise plays this to a T. Emotionless though she warms up later, petite, platinum blonde hair, not human, and was created by [[spoiler:St. Maximus Ariels]].
* [[MeaningfulName Eva]] from ''VideoGame/CrushCrush'' has green hair and gold eyes, but otherwise is a very clear expy of Rei as a mecha pilot you save from dying who's an emotionless, [[SpockSpeak Spock-like]] MysteriousWaif until you gradually teach her how to smile. She even mentions [[BandageBabe wearing bandages]] to a party at one point and says that [[{{Tsundere}} Cas]][[GirlishPigtails sie]], another girl in the game, reminds her of one of her colleagues.
* [[MeaningfulName Kuu Dere]] from ''VideoGame/YandereSimulator'' and ''Kuu Dere Simulator'' is based on Rei Ayanami and has the standard short blue hair and red eyes. Her bio in-game states that no student has ever seen her show emotion, something which is an InformedAbility currently because she'll run away in terror like anyone else if she sees Yandere-Chan commit murder and will threaten her to tell anyone what she has done if she tries to speak to her the following days, as well as damage her reputation. However, in the future she'll have the "Apathetic" persona, which will literally show no emotion.
* Fie Claussell from TheLegendOfHeroesTrailsOfColdSteel fits the archetype to a T. She's a quiet, stoic 15-year-old with exceptional combat capabilities who is eventually revealed to be [[spoiler: [[ChildSoldier a former Jaeger from the Zephyr Jaeger Corps]] and adoptive daughter of the corps's boss, The Jaeger King.]]
* Pandora from ''VideoGame/MegaManZX''. A [[EmotionlessGirl Emotionless]], [[YouGottaHaveBlueHair green-haired]], [[RedEyesTakeWarning red-eyed]] [[RidiculouslyHumanRobots reploid]]. Her and her brother act as CoDragons for the BigBad and their origins remain a mystery until their DarkAndtroubledPast is revelead late in [[VideoGame/MegaManZXAdvent ZX Advent]].

[[folder:Visual Novels]]
* Primula of ''VisualNovel/{{Shuffle}}''. A young EmotionlessGirl with very light purple hair and pale skin. In the anime, emotions cause her magical powers to go haywire. In the visual novel they're hoping she can gain emotions to show the program she's part of is a success, putting her into a human environment is part of the program, her magic has little to do with it. In both she is an artificial lifeform.
* Kyoko Kirigiri of ''VisualNovel/DanganRonpa''. Purplish white hair, purple eyes, stoic and mysterious (even her talent is just listed as "???"), she [[spoiler: is the estranged daughter of the school headmaster and was also secretly amnesic the whole time]]. She also gradually warms up to the main character.
* Saber from ''VisualNovel/FateStayNight''. Fair hair and skin, not completely human even when she was alive, and an emotionally cold demeanor that comes to defrost thanks to the protagonist's actions.
* Kei Ayamine from ''Franchise/MuvLuv'', a short-haired purple eyed {{Kuudere}}. Bonus points for her name. The only thing that sets her apart from other examples is that she's also quite TheGadfly.
* And of course, Ruri Shiromizu from ''Season of the Sakura''.
* Mio Nishizono from ''VisualNovel/LittleBusters'' has short blue hair and amber eyes and is stoic.

* Iriana Estchell from ''Literature/IlivaisX'', offering nearly every aspect. The one place she differs is that she's trying to AVOID [[BecomeARealBoy becoming more humanly expressive]].
* Freelancer Agent Texas from ''Machinima/RedVsBlue'', specifically after her past is revealed in Seasons 9 and 10.

* The version of Raven in the {{Animesque}} ''WesternAnimation/TeenTitans'' cartoon is modeled after the archetype. [[AdaptationDyeJob They even change her black hair from the comics to blue-purple]]. However, Raven is [[TheSnarkKnight notably snarkier]] than most examples.
* Despite being quite outgoing and sociable, the titular character of ''WesternAnimation/GetEd'' bears many hallmarks of this trope, from eyes which glow red when he is angered, the blue color scheme of his suit and the fact that he was [[spoiler: genetically engineered by Ol'Skool from an ancient artifact]]. He is also plagued by 'visions', a lack of knowledge of the outside world and strong desire to know about his past.
** Sadly, due to the creator of the series passing away we never fully see the resolution to this.
* ''WesternAnimation/NeoYokio'': Helena, a monotone and aloof woman with purplish-blue hair and purple eyes. After [[spoiler:being possessed by a demon and falling down a flight of stairs]], Helena dons a hospital gown and head bandage for most of the series. Giving up her former life as a fashionista, Helena becomes reclusive and rarely shows any emotion besides her annoyance towards Kaz. She even [[spoiler:steals and pilots Charles the mech-butler to escape Neo Yokio at the end of episode 6.]]
