Uncanny Valley Girl

I just, like, stabbed some loser to death.

She's cute. Beautiful, in fact. Friendly and popular. She's the head of the class in terms of looks, money and everything that counts for her approval rating, but she's not the Alpha Bitch, even if she has a Girl Posse or the entire grade on her side. One of Those Two Guys might have a crush on her, even though he never gets anywhere. She's the perfect girl...

...except there's something not quite human about her, and she's secretly out for your blood.

The Uncanny Valley Girl is smarter than she lets on, and puts on a very convincing persona that's made the class adore her. It's the high school girl version of Villain with Good Publicity, except the publicity is good enough that nobody, not even The Hero, knows she's the villain — or anything other than normal. Not until she comes at you with a sharp object, that is.

Compare Yandere, Cute and Psycho, Stepford Smiler, Living with the Villain, Dark Magical Girl, Faux Affably Evil, and Bitch in Sheep's Clothing. Contrast Alpha Bitch, Fallen Princess, Loners Are Freaks. In extreme cases, she may be a Humanoid Abomination.

Note that the focus is on the words "Uncanny Valley". The "Valley Girl" part is Just for Pun.

  • Ajimu Najimi of Medaka Box looks like a sweet angel and Too Good for This Sinful Earth, but it turns out she views people as indistinguishable from furniture and only seeks for a way to entertain herself.
  • Haruhi Suzumiya:
    • Ryoko Asakura —the Uncanny Valley Girl. She keeps up her charming persona and amazing smile even while trying to gut Kyon. She provides the trope picture.
      Asakura: You think it's a... joke? Huh. You don't wanna die? You don't want me to kill you?
    • In the tenth novel, Emiri Kimidori is revealed to be every bit as apathetic towards human suffering as Ryoko, just less proactive about it.
    • We eventually meet Kuyo Suo, a humanoid interface like Yuki. Unlike Yuki, she's an interface for the Heaven Canopy Domain, and is so completely alien that normal humans won't even acknowledge her presence. She speaks in stops and starts, inserting somewhat relevant phrases she clearly doesn't understand the meaning of here and there. She rarely moves, instead preferring to just appear places, and overall gives the impression of someone who simply has no idea how living things, let alone humans, act.
      Kyon: A cardboard cutout would have had more life than her.
  • In Shin Mazinger Zero three beautiful, tall, ponytailed, blonde triplet girls called Gamia Q1, Q2 and Q3 transferred to Kouji's high school. Given that they were gorgeous and friendly, even if they behaved in a strange fashion and looked a tad weird, all boys in class started to quickly slobber at them. In reality they were three androids (appeared for first time in the Mazinger Z original manga and Mazinkaiser) sent to assassinate Kouji Kabuto. Seemingly Kouji bought their masquerade, but shortly after he suggested them dropping their act, and he revealed that he had suspected it all along.
  • Mio Hio from D.N.Angel fits this to, like, a really creepy T! She's an American Expy, even has one of Those Two Guys when she's after the other to either kill him or bind his Superpowered Alter Ego Phantom Thief. Death Equals Redemption, which is, like, a drag.
  • The Vampire Princess Miyu OAV gives us a schoolgirl named Ranka. She's pale, beautiful, elegant, sweet tempered and ensnared the heart of the local Chick Magnet... she's also a Shinma that transforms people into dolls. Her guy knows it and loves her that way.
    • To a certain degree, Miyu herself counts when she poses as a schoolgirl to fit better in the human crowd.
    • Did we forget how Chisato Inoue became one of these after her Shinma awakening and her Face-Heel Turn? Brrrrr...
  • From Mai-HiME, there's Miyu Greer's adorable little charge/soulmate, Alyssa Searrs, the Golden Angel of the School Choir.
  • Johan Liebert from Monster decides to pull a stint as an Uncanny Valley Boy in volumes 6 through 9, when he starts attending University of Munich as part of a plan to get at Hans Georg Schuwald and puts up a front of the most mind-bogglingly perfect human being in existence. When Schuwald is finally confronted with the possibility that his new student secretary is a psychotic bastard that's probably planning to kill him, Schuwald isn't even the least bit surprised. Why? Because he was so damn perfect that he just had to be evil.
  • The mysterious transfer student in Saitama Chainsaw Shoujo seems pretty unfazed when she encounters the blood-drenched, murderous protagonist... complete with giggling and smirking while throwing her "boyfriend" towards Fumio's chainsaw.
  • Haruna Niekawa from Durarara!! Though it's mainly due to her being possessed by a Yandere Living Weapon.
  • Ryuuko Kounuma from Wolfen Crest. She seems nice enough, is rather charming and carefree... Except she is completely psychotic underneath. Having spent several years under the sexual abuse coming from her dad and her pimp, she deals with it by having sex with lots of men and ruin their lives ruined afterwards, to an insane extent. She doesn't fit the Emotionless description, though, as she's pretty much Ax-Crazy.
  • Nui Harime of Kill la Kill fits this trope like a specially tailored suit. She's cute as a bug, dresses in fashionable sweet Lolita, and always wears a big smile on her face. She also moves with Limited Animation, can reach through a Split Screen and possesses uncanny strength and speed. She also does whatever the hell she wants, and greatly enjoys the sight of carnage, especially if she's the one causing it.
  • Discussed in Attack on Titan. Eren Yeager accuses School Idol Krista Lenz of being one, stating he always found her false perfection incredibly creepy. While not quite a murderous psychopath, when she isn't pretending to be The Ingenue, she can be incredibly callous about the lives of her comrades and even admits she doesn't really understand the feelings of other people. She's getting better, though, and learning to be a real person.
  • Kyoko of Is This a Zombie?, an old friend of Orito, and the only survivor of an attack by the same serial killer who murdered the protaganist, Ayumu. She survived because she is the serial killer who murdered Ayumu, and she's murdering people so she can collect their souls to earn more than one life, effectively making her immortal. She's also actually a Magical Garment Girl, and was modifying Orito's memories to make him think they've been friends since childhood.

     Comic Books  
  • In X-Men, the seductive Foxx turns out to be the shapeshifter Mystique trying to seduce Gambit away from Rogue. A similar plot occurred in X-Men Evolution, when Rogue's friend Risty Wilde turns out to be Mystique spying on/stalking her adoptive daughter.

  • In Basic Instinct, Sharon Stone's character Catherine Tramell is this. She is a beautiful, wealthy, brilliant author but embodies this trope with her fondness for ice picks
  • Alice from Transformers: Revenge of the Fallen. She looks like a hot blonde who can't keep her hands off Sam, but she's actually a Decepticon who's after the Allspark info in Sam's brain.
  • Asami in Audition seems like the girl of your dreams. However, when she asks you to love only her, she means it.
  • Ex Machina:
    • Ava, to a degree, considering she's clearly designed to resemble and act human, but very clearly isn't. When she puts on clothes and a wig, she could easily pass for a human if she had put on a scarf to cover up her metallic nape and the "skin" her clothes didn't cover (and also if she didn't make a buzzing noise when she moves).
    • Kyoko's lack of vocalization is also rather disconcerting. When she starts peeling the skin off of her face, it gets really disturbing.
    • Ava had several predecessors, all of whom were nude in their flashback footage. One had a time lapse of being built up from a pair of legs, section by section, then doing a Sexy Walk, which dives right into Fan Disservice. Another, we see as a completely skinned woman minus the metal skull and neck vertebrae; Nathan dragging around her lifeless body like a corpse was...creepy. Another one, apparently "Jade", was being interviewed by Nathan and demanding to be let out in her concurrent interviews, until she was clearly desperate and panicked. Her footage ended on her having a Freak Out and battering at the door until her arms disintegrated, and eventually gave up, crying. Had she been human, her hands and forearms would have been worn down to the bone.

  • Tammy manages to conceal the fact that she's the high priestess of a cult trying to bring about the end of the world, and the one responsible for the plague of zombies in "Gil's All Fright Diner" , despite that the townsfolk (as well as the drifter two main characters) are VERY experienced with the supernatural. This may be because she uses her great female beauty to distract and manipulate all males in the book. The fact that she only has one cultist to aid her (her would-be boyfriend) and is a teenager probably doesn't hurt, either.
  • Lilith from The Mortal Instruments is described as beautiful, but unsettling.
  • In Percy Jackson and the Olympians book 4, Percy starts off the book by meeting Kelli and Tammi, two beautiful cheerleaders. They later turn out to be monsters concealed by the Mist, and they try to kill Percy. Oh, and they're also part of Kronos' army.
  • In the Uglies series, the "Specials" are essentially this: Tally describes them as being very beautiful, but a mean, threatening kind of pretty.

  • In an old text game you met a woman whose figure was described, to begin with, as "impossible" or "implausible". And you could sleep with her if you wanted, but then she turned out to be a monster that fed on Life Energy and you get a Non-Standard Game Over.
  • Tsukihime, a stand-out Visual Novel, can feature more than one of these depending on the route you take. The stand-out example, however, is Kohaku. On first appearance she's the one ray of cheerful Meido-shaped sunshine in an otherwise cold and unwelcoming Big Fancy House; but delve into the Far Side routes, and when you see her real smile... eep.
  • You know there's something wrong with Yandere-Chan from Yandere Simulator when the cute girl starts laughing and giggling in front of a corpse.
  • Orianna, the Lady of Clockwork from League of Legends is an example of a girl who approaches the Uncanny Valley from the other side. A clockwork-powered automaton in the shape of a beautiful girl, Orianna was created as a Replacement Goldfish by a genius clockmaker who never got over the death of his daughter. Unfortunately his creation ended up as something described as a "clockwork killing machine". While Orianna could never be mistaken for a human, she believes herself to be alive and tries her best to act in a manner she perceives as "normal"- except she has a very skewed perception of what "normal" is. As a result she's described as being far more creepy than the League's other robot, who doesn't even look SLIGHTLY human beyond his basic shape.
    This thing seemed dead inside. It seemed like an automaton, trying to act like as if it was alive. The effect was unsettling.
    It's not that she didn't have facial expressions ľ they were just wrong. There was something in everything she did that was just a little bit off, off enough to be just this side of completely alien.

     Western Animation  
  • In the episode of W.I.T.C.H. "T is for Trauma", Big Bad Nerissa disguises herself as the beautiful Stacie, showing up at Sheffield Institute in order to lure the heroines' boyfriends away and to spy on them. In addition to being beautiful, she uses a spell to make every guy in school completely crazy for her (except Will's boyfriend Matt, who was immune because Nerissa had already messed with him).
  • Invader Zim could be seen as a subversion of that trope, except that he's not a girl. Tak (who is a girl) is a somewhat straighter example.
  • In The Oblongs, Milo gets a crush on an alien who infiltrates not only his school but also the Debbies' clique, despite her Paper-Thin Disguise.
  • As mentioned, Risty aka Mystique in X-Men: Evolution.
  • In Ben 10: Ultimate Alien, Elena Validus becomes this after the Hive infected her and turned her into a Yandere for Ben.
