Enfant Terrible



"A little child, she was. But also a fierce killer...Now capable of the ruthless pursuit of blood, with all a child's demanding."

- Louis

They're adorable children. An angel, one might say, with a cherubic face. One just wants to pick them up and hug them.

Pity they're psychopaths. An Enfant Terrible knows people think they're cute, and will use that to their advantage. When one person finds out, said hero usually has a hard time convincing others, who will turn on them for even suggesting such a thing about the poor, poor child.

An Enfant Terrible may be supernatural, or simply a child born without a conscience. They may also be an Evil Orphan - possibly of the self-made variety.

A form of the Devil in Plain Sight. Might overlap with Girl Scouts Are Evil, if they do more than just sell you cookies, and with Kids Are Cruel, if the kid's behaviour also transpires in his relationship to other children. Akin to the Creepy Child, except Enfants Terribles are truly dangerous and vicious at heart, whereas a Creepy Child isn't necessarily psychotic or evil.

Of course, such a character almost always plays the Wouldn't Hurt a Child and Children Are Innocent cards to get away with their actions, which almost always works—for a while. They're unlikely to be directly killed by any heroic character in the story, but they have a habit of becoming Self-Disposing Villains.

See also Corruption by a Minor, which is often this character's favourite technique to get what they want, and Undead Child for a common subtype. Often the nemesis of a Kid Hero.

Compare Tyke Bomb, Little Miss Badass, Yandere, Cute Is Evil, Fetus Terrible and Cute and Psycho. Contrast with Psychopathic Manchild, where a teen-aged or already grown psycho acts like a child. Contrast Goo-Goo Godlike, in which the child is not evil, just playful and way too powerful.

Not to be confused with Les Enfants Terribles.

Anime and Manga

 * The Monster.
 * Elfen Lied is about a race of superpowered psychotic little girls called The Diclonius.
 * And one of them met her "match" in a bunch of really cruel and really stupid kids from an orphanage. Guess what happened.
 * The little girl assassins in Gunslinger Girl may also be viewed as Enfants Terribles, although they have been specifically Brainwashed and manipulated into being that way.
 * Noir is a case where the Enfant Terrible gets a bit better, more or less.
 * Wen from the Cowboy Bebop episode Sympathy for the Devil is a killer who stopped aging in his childhood after exposure to Green Rocks.
 * Excel Saga has an example of this: [[media:1109068744777.jpg|Cosette]] from the episode "Increase Ratings Week" is an eight-year-old assassin.
 * On a similar note, Cynthia from Overman King Gainer is a perfect example of this. She's an elite soldier working for her foster father, who enjoys killing and likens it to a game - except she knows she's actually committing horrible crimes. However, her father legitimately loves her and is proud of her for her deeds, so she might just be the perfect soldier.
 * In her early appearances, Ririn from Bleach used the trope for her facade. During one of the fights, despite everything she had brought down on them, both Ichigo and Renji make note of how hard it is to fight brats, and instead opt to attack her two minions.
 * Gin Ichimaru, however, was shown to be pretty darn creepy and evil as a kid when Aizen recruited him in the flashback Turn Back the Pendulum Arc.
 * And then there's Yachiru. Not necessarily evil, perhaps, but the fact that, as a toddler, she was entirely unafraid of a very large and blood-covered man who had been killing people in front of her is supposed to be significant. Then she was raised by that man, and enjoys watching him "fight," which usually means "slaughter."
 * As well as the fact that her Spritual pressure is insane and her aura is shaped like a demon, even fellow squad 11 Blood Knight Ikakku (Strong enough to be a captain if wanted to) is absolutely terrified of her.
 * Masato from Mermaid Saga who is an adorable little child who happens to be an 800 year old sociopath known for poisoning women with mermaid's flesh in hopes for the Million-to-One Chance (an actual one, not the type that occurs nine times out of ten) that it might make her immortal instead. Of course, the "lucky" one who doesn't die an agonizing death doesn't have it much better either, as he tends to punish them by repeatedly killing them.
 * Michio Yuki of MW converts from a sweet, adorable kid to this. It happens to him because of being exposed to the titular Psycho Serum.
 * Dio of JoJo's Bizarre Adventure as a child killed his father, got adopted into the rich family of the main character, made said main guy look like a bitch for all of his early childhood years, kissed the girl that the main guy liked, burned his dog in an oven, and beat him up in a boxing match. And this is all before he becomes a vampire and causes trouble for three of the main character's descendants. His primary motivation for the vampirism? The main guy beat nine shades of hell out of him for having kissed his girl, so he decided to get back at him in the worst way possible.
 * In Part 3, the user of the Stand Death 13 is a remarkably intelligent and sadistic baby. Whenever his victims fall asleep, Death 13 pulls them into a dream of an amusement park and kills them; his Stand makes it real. Should they escape, they have no memories of the dream.
 * Hansel and Gretel of Black Lagoon play this archetype well past the hilt with their childish fits of pique-turned-bloodbaths, shared multiple personalities, laundry list of psychosexual disorders, and cutely-adorned heavy machinegun. They aren't supernatural, their immunity to recoil forces aside, but they are very, very messed-up.
 * Luki and Noki from DOGS Bullets and Carnage, particularly the aptly-named DOGS: Hardcore Twins. They fight with a gun and a claw, both huge, and boast that they leave an ocean of blood wherever they go—all while treating it as a fun game.
 * Saffron, Ranma's final foe in Ranma ½, first appears as a very nasty child with a chip on his shoulder and a kingdom of powerful, flying soldiers at his beck and call. He later acquires his true, mature form and proceeds to devastate half the countryside.
 * Narrowly averted with Tokito of Samurai Deeper Kyo, who is referred to as sadistic by one of the characters (who isn't a very nice guy himself, when it comes down to it) and has a lot of onscreen fun torturing people, both psychologically and physically. Eventually, though, she is redeemed.
 * Vino from Gash Bell is an INFANT whose demon partner is more or less Hitler mixed with Satan. And he enjoys watching him destroy the world. After his demon partner is killed one of the main characters adopts him because he's just a baby, but I would have electrocuted the little fucker right there.
 * from My-HiME. Sure, she's huggably cute, but you'll soon forget about all that when you realize that she can call an army of tanks to your doorstep...and she's not afraid to order to shoot to kill. Just don't look up at that metallic thing floating high above the ground.
 * The Fifth diary holder, Reisuke Houjou in Mirai Nikki is one of these, being an adorable four-year-old who uses his magic picture diary to adorably kill people (i.e., asks a girl to take a bath with him, and then tries to electrocute her). He has a Freudian Excuse that his parent's didn't love him enough (they never "slept like a river", next to each other with him in between) . Well, that and God is telling him to kill people. No, not as in he's hearing voices that he attributes to God, but as in God exists, and he's telling a four year old to kill people (and he tells that to other people, too. Because he's THAT much of a prick.).
 * As a small and relatively cute child, Gaara reacted to another child's rejection by trying to kill her. Hard to blame him, though, after all the Mind Screw-ings his family gave him.
 * from Gundam AGE takes this trope Up to Eleven. While he's only seven years old, he's done more than his fair share of heinous acts (which is to be expected for )
 * Yu-Gi-Oh!
 * Mokuba Kaiba comes disturbingly close to this in the beginning of the manga (when he's still ), but he gets better afterwards. Seto Kaiba around the same age (flashbacks) might have been even more dangerous. He still is.
 * In the parody Yu-Gi-Oh!: The Abridged Series, the little girl with her teddy bear
 * The little girl herself is harmless, it's the teddy bear that's evil. Even then, what can a teddy bear really do?
 * Noah Kaiba from the Virtual Nightmare Filler Arc is Seto and Mokuba's adoptive brother. Seriously injured just prior to their adoption, Noah's mind was placed in a virtual environment that preserved his conciousness but at the cost of permanently stunting his emotional growth. Despite being in his late teens or early twenties, he still appears as a child within the virtual world, and acts like one as well.
 * Third-party villain Tron from Yu-Gi-Oh! Zexal is a child wearing a Elizabethan-style outfit (much like his three henchmen do) and an iron mask.
 * Despite not having a humanoid form, Ghost in the Shell: Stand Alone Complex's Tachikomas evoke this at times, speaking with cute, childlike voices and behaving in cute, childlike ways just before cheerfully shredding a whole platoon of infantry with a Gatling gun.
 * Fullmetal Alchemist has.
 * is like the inverse of the Psychopathic Manchild (a "childman", perhaps?), having the form of a child and the mind of an evil, evil, EVIL man.
 * Actually, as of chapter 106, it appears that  really does have the mind of a child - just a horribly evil one. After all, all he wants to do is make his Father happy, and if it means slaughtering a few million innocent people, then so be it.
 * In the 2003 anime version, there was Wrath after being corrupted by Envy and remembering his past, but after a while.
 * Ralph from Glass Fleet may be adorable and loving most of the time, but he won't hesitate to attack and try to kill you if you get on his bad side.
 * Himeko from Shinigami Trilogy is basically Mandy with the ability to be deceptively adorable. In fact, she looks suspiciously like a certain DeviantArtist's version of Mandy, and combined with her grim reaper suitor they look like Mandy's children Mini-Mandy and Grimm Jr.
 * from Shugo Chara.
 * Baccano! (see trope quote 2) has someone who (probably due to horrible torment and constant fear) turned into one. Though it might be just a overcautious kind of self-preservation.
 * If Maria Ushiromiya from Umineko no Naku Koro ni isn't one normally (it's unclear), she definitely was one when she Not that she doesn't have a massive Freudian Excuse...
 * Although he may be a bit too old to count but 16 year old Hajime Muroto from Gantz certainly displays the traits, he plays it out like he's a very innocent and sensitive boy, but as it turns out he's a dangerous psychopathic serial killer and rapist.
 * Kouganei Hana from Karakuridouji Ultimo. A cute little tyke, when she isn't smiling like a lunatic and ordering her giant killer robot to murder everything in sight.
 * Isaac, the prepubescent mass-murderer from Eternal Sabbath. In his defense, however, he has one hell of a Freudian Excuse: He was raised in a vat to keep him from developing consciousness, but being telepathic, he has known of his intended purpose since infancy, and has consequently developed a rather poor opinion of human morality.
 * Gerard (technically Jellal) from Fairy Tail. While he's an adult at the start of the story he convinced everyone to be his slaves as child because they thought he was a sweet, morally righteous kid.
 * Subverted with V.V. in Code Geass; even though he looks like a little kid, he is really in his late-50s/early-60s and has a Code for immortality.
 * Played straight with . The kid is an assassin, who's been killing people since he was a small child. Nobody would suspect a six year old to shoot someone, but it helps that he can.
 * Ginger Bread of Katekyo Hitman Reborn.
 * Except that he's actually a doll, that's being controlled. Lambo or the Arcobaleno babies would fit better, even though they were adults transformed into babies.
 * The purest form of Majin Buu was Kid Buu, a child-like form of Buu completely lacking any sense of morality or moderation. Essentially, his first act on being cleansed of those features absorbed from past victims was to blow up Earth while still on it, reform himself, and start blowing up other planets while trying to find Goku and Vegeta.
 * In fact, when he was first released, his first act was an Earthshattering Kaboom... on 700 planets all at once. Something like that would definitely get the attention of the Kaioshins.
 * Young Knives from Trigun he simultaneously murders and breaks up the crew of the ship who adopted him and Vash, and in the end he leaves everyone including Vash's beloved mother figure to die on the ship after he causes it to blow up.
 * The Digimon Emperor  from Digimon Adventure 02 has elements of this, but a lot of that is due to the fact that he simply doesn't realize that the Digital World is Not a Game  . Just watch his childlike glee when he creates the Dark Spiral and Chimeramon.
 * Rurouni Kenshin has Soujiro and Enishi. The former's a Stepford Smiler serving a Social Darwinist, the latter is a Yandere who severely lacks empathy, and both can cut people down into hamburger.
 * Medaka Box has Unzen Myorii, the first Big Bad after the Genre Shift. He's a ten-year-old cute little boy who's Establishing Character Moment is him breaking the Orchestra Club leader's arm, and then massacring the entire club for being too loud.
 * Medabots has the Ankle Biters, whose Medabot, Churlybear, is a deceptively powerful Gravity Master. Though they don't exactly kill anybody, they are nasty pieces of work, though granted, Spyke kinda had it coming.

Comic Books
""All those years of dipping from the same genetic pool caused a wrinkle, a flaw in an otherwise normal family line. We set out to keep ourselves above the common man and found ourselves with a thing from the deepest pit of the Sith.""
 * Malice Vundabarr of Darkseid's Female Furies in The DCU.
 * Another example from The DCU: In the comic book L.E.G.I.O.N. '94 (basically the "modern-day" version of the Legion of Super-Heroes), the superintelligent Lyrl Dox took control of the intergalactic police force L.E.G.I.O.N. from his father, Vril Dox (the son of Brainiac), brainwashed all but a handful of the force's members, and turned it into a fascist organization that nearly took over the universe. All of this before his second birthday.
 * Calvin, from Calvin and Hobbes fits most of the requirements, but he doesn't get away with it.
 * Jenifer, from a '70s comic by Bruce Jones. She's got some sort of preternatural power that she uses to seduce men and rob them of their logic, driving all their friends and family away and then raping them repeatedly, Naturally, as this is a comic, her hideous deformity should be a clue. (Try YouTubing the TV version, as well—there's some pretty sick stuff there.)
 * Though said TV version plays her somewhat more morally ambiguous. Rather like a wild animal actually.
 * Oliver AKA Kid Omni-Man from Invincible - imagine an evil, 10-year old Superman with super-intelligence slowly going more and more insane while everyone around him ignores all the obvious signs.
 * So, kinda like a kid version of Superboy-Prime?
 * And that's not
 * As of now, it appears that . Probably.
 * X-23 of the X-Men is a rather good example. She is Wolverine's clone and was raised from birth by a Government Conspiracy to be a killing machine and often is able to carry out missions because she is so cute that no one suspects her.
 * Same goes for the Cassandra Cain Batgirl, minus the government, plus an abusive dad.
 * Similar to Cass is Batman's son Damien Wayne. Raised to be an assassin by his mom Talia, he has a major case of Raised by Wolves.
 * In Earth X, the new Red Skull is a 12-year old blond boy named Benny Beckley with mind control powers. Aside from attempted world conquest his crimes include killing Doc Samson (by forcing him to tear himself apart), his aunt, Normon Osborn, and others.
 * By the time he actually starts taking over the planet, he seems to be about 16 or 17, at least.  still nearly gives Captain America a Heroic BSOD.
 * The Fantastic Four actually fought a villain named Enfant Terrible. Turns out it was just a misunderstood alien child. It almost destroyed Earth by pulling the sun closer to it simply because it found this glowing ball in the sky fascinating, for one.
 * BPRD 1946 has a demon that stayed on Earth in the guise of a little Russian girl.
 * Ashley in Hack Slash. Beat his own brother to death with a toy truck for playing with it, and was smothered to death by his outraged mother with a teddy bear. Survived as a vengeful ghost murdering other children in their dreams. Then ended up
 * Klarion (bum..bum..BUM!) The Witch Boy.
 * Prince Harrandatha Estillo from the X Wing Series comics. He's Royally Screwed-Up.


 * I Luv Halloween - Moochie, oh my dear motherf* cking god, Moochie!! She takes enfant terrible and ups it up to eleven (probably twelve)! She kills an obnoxious teenage couple and a young boy by bashing their heads in with a bra-slingshot, mutilates an unfortunate doctor (by applying him with electric shocks and stabbing scalpels into his thighs), pulls out teeth from dead and living alike (she was dressed as the tooth fairy), and her mile-wide pet cemetery implies no animal ever lasts more than five minutes in her care. She's also accompanied in her murderous hijinks by Spike, who is more of a creepy child than enfante terrible. All of this is for comedy.
 * Hell, nearly the entire main cast is made of enfante terrible. In one volume, after being taken in by a Christian couple, whose fear for Finch and Mr. Kitty's safety is misguidedly justified due to being in the midst of a zombie apocalypse (the kids themselves don't care what's going on as long as there's candy), they set fire to the husband's wife before escaping.
 * Finch (who happens to be the leader of the loosely-knit tricker-treaters) does it again when an old woman gives him an apple for candy, which he sees as unforgivable. If he doesn't get any treats, then the old woman gets "tricked", when Finch and his gang give an apple stuffed with razor blades to a town cop, whose death prompts the woman to get arrested.
 * Hit-Girl from Kick-Ass. While in her civilian garb she plays off as an innocent little girl, but outside of this, due to Training from Hell from her father, she is incredibly skilled with any weapon but she favors swords and knives in particular and can slice through an army of thugs in minutes and can shatter a man's leg with a single kick. She does all of this with sadistic glee, and she's one of the good guys.
 * The villains of the X-Men event "Schism" are a quartet of rich 11-to-12-year-olds who have joined the Hellfire Club. They include the new Corrupt Corporate Executive of the company that manufactures sentinels, who got the position by murdering his father and blackmailing the board of directors; a Bavarian child prodigy descended from Victor Von Frankenstein; an Ax Crazy Little Miss Badass hotel heiress; and a West African Self-Made Orphan who's taken over his family's slave trading empire.
 * Recent X-Force villain Genocide is a ten-year-old boy. A giant, radioactive skeleton in an intimidating-looking containment suit, but a ten-year-old boy. He's got enough nuclear firepower to blow up an entire town, and he curbstomped Wolverine. Subverted in that he doesn't appear to be a "bad" kid, exactly, he just admires and tries to please really bad people (the followers of Apocalypse, if you must know).
 * Numerous characters from British Humour Comics fit this trope, examples include Ivy the Terrible and Bea from The Beano Cuddles and Dimples from The Dandy and Sweeny Toddler from Shiver And Shake, Whoopee! and Whizzer and Chips.
 * Jimmy Marks aka Hybrid. The son of a human woman and a Dire Wraith. He started out as a relatively normal child, but when a bunch of his dad's old comrades showed up looking for him, they took an "interest" in the boy and taught him the ways of power and evil. Jimmy took to their lessons like a fish to water and started terrorizing his parents (even his Dire Wraith father was terrified) and killing livestock For the Evulz. Even worse, around this time Jimmy's mutation—extremely potent Psychic Powers—also manifested itself. Psychic powers, the ability to go One-Winged Angel into a super strong Nigh Invulnerable monster even fouler than a typical Dire Wraith, and a penchant for evil that terrifies his own Dire Wraith father (who is a member of one of the most evil races in the Marvel universe, which is saying something) -- not a good combination. In his debut he ages his own mother to death, impales his father with a pitchfork when dad tries to kill him out of remorse for letting him become a monster, engineers a Let's You and Him Fight scenario between Rom and the X-Men by pretending to be a helpless child, and tries to abduct Kitty Pride for breeding purposes. Hybrid was so evil that Rom was willing to set his weapon to "kill" when Hybrid proved too powerful to be banished to Limbo. Hybrid not only survives, but gets worse with each later appearance. In Avengers Academy, he pulls the exact same "helpless youth" act to get admitted into the Academy, all so he can enslave everyone there and make the men his soldiers and the women his breeding partners.

Fan Works

 * Princess Jody from Super Milestone Wars, subverted since she's older then she look, she's actually over 1000 years old
 * Deconstructed in the Firefly fanfic Forward, where the resident psychopathic child is a mind-controlling girl created by the Academy. The deconstruction comes from the fact that the child in question is impulsive and irrational, going on violent rampages whenever she thinks she's encountered someone connected to her torture. This ultimately leads to both  and   tracking her down, by essentially following the trail of corpses.
 * in With Strings Attached was an elven woman of unknown age who was murdered and then reborn as a five-year-old boy. Given her taste for sadistic jokes (that's why she was murdered), considerable knowledge, and willingness to step on people to get what she wants, she qualifies.
 * In Attack of Giygas, we have Porky and Ashley. Ashley ends up turning  into one.

Film

 * Damien from The Omen.
 * The kids from Village of the Damned.
 * Stepping away from the supernatural, there is The Bad Seed, which was a 1956 theatrical film (in which the Enfant Terrible was named Rhoda) and a TV movie in 1985 (where she was named Rachel).
 * Several classic horror-movies are filled with them, including the Stephen King adaptation Children of the Corn and its sequels.
 * Chucky from Child's Play is similar, as an adult serial killer who has transferred his spirit to a childlike doll, and who often uses the cuteness/innocence aspect to get what he wants.
 * In The Good Son, the murderous title character is a Gender Flip version of the aforementioned Bad Seed.
 * It's Alive! is about a malevolent baby. Within minutes of its own birth, it kills everyone in the room except mom.
 * David Cronenberg's The Brood has
 * The unstoppable Paperboy from Better Off Dead pursues Lane throughout the movie, demanding the two dollars Lane's family owes him. He also duplicates himself/recruits an army of identical helpers, and survives falls that should kill a human.
 * The recent underrated film Orphan stars a serial killing orphan It's a lot smarter than it sounds on paper.
 * Samara in the remake of The Ring was aged down from 40 or so in Ring to about 12. Oh, and she can drive you insane or kill you with her mind. Even after death.
 * The title character in Joshua was possibly one of these. Bu it is also possible that everything that happened was just happenstance and misunderstandings. In the final scene,.
 * The title character in Mikey is one of these as he is a seemingly innocent child who is actually a psychopath who murders his foster families or anyone else who makes him really angry.
 * Men in Black lampshades this in a scene involving a shooting gallery filled with aliens. While the other MIB applicants shoot at the aliens (who're actually just working out and sneezing), Will Smith's character shoots the lone civilian, "a white girl, eight years old, taking a stroll in the ghetto with all these monsters while carrying quantum physics books".
 * This originally appears to be a stupid mistake on the part of Will Smith's character, but further into the movie it is revealed that she really would be the only suspicious person in such a situation.
 * In Bloody Birthday three children Debbie, Curtis, and Steven have no consciences and murder anyone either because they feel like it or feel they have wronged them, it was foretold in the movie that anyone born during an eclipse would cause them to behave that way.
 * In Halloween, Michael Myers is six years old at the time of his first murder.
 * Even more so in the remake, with Deborah finding the notion of Michael killing animals unbelievable. Until he graduates to people.
 * Oogie Boogie's hench-children Lock, Shock and Barrel from The Nightmare Before Christmas. While discussing their objective of kidnapping Santa Claus, the possibility of killing him in various ways also comes up.
 * While not cute per se, Winchell in North certainly is terrible, a Smug Snake really. This preteen school newspaper editor encourages the hero's search for new parents and publicizes it. While North's out searching, Winchell spearheads a powerful movement to make all parents subservient to their children. When he realizes that North choosing to return to his real parents would spoil things, he tricks North into thinking they no longer love him—then sends assassins (adults) out to kill him.
 * In Who Can Kill a Child?, children on an island of the coast of Spain for no particular reason start murdering all the adults until only they remain and they go off recruit other children for their killing spree.
 * The only explanation for their psychotic behavior as one of the initial survivors claimed that a virus that only affected the children may be causing them to act like that.
 * Jody Mitchell from Daddy's Girl is a psychopathic little girl who kills anyone who gets in the way of separating her from her beloved father.
 * Claudia from Interview with the Vampire is a little girl who was turned into a vampire by Lesat to give Louis a surrogate child. Upon becoming a vampire, she is a blood-thirsty murderous child who lures people to her by pretending to be lost so she can kill and feed off them.
 * Parodied in Mafia with Chucky, a psychotic little boy who is a parody of Chucky from Child's Play he murders his grandfather with bug spray so that he can steal his wallet and his father can become the new godfather, he is later seen torturing animals and stabbing dolls, and he gets his comeuppance when he receives a package of tiny dinosaurs which eat him alive.
 * The Children semi-combines this with Zombie Apocalypse, as an unknown sickness affecting only children turns them into murderous sociopaths who are of course very good at faking innocence.
 * The main character on The Tin Drum is more of a sociopath than a psychopath but he's still terrible nonetheless.

Literature
"Lord Hellebore: That child is an abomination. Remover of Inconvenient Obstacles: Then you have achieved your purpose, my lord."
 * The two children, Miles and Flora, in Henry James' The Turn of the Screw. Although there is some speculation as to whether or not they really were Enfants Terrible or whether the narrator was insane...
 * Claudia in Interview with the Vampire. She's Really Seven Hundred Years Old, though.
 * Tulip, from Anne Fine's award-winning children's book The Tulip Touch, is another example.
 * Acheri, from Hell's Children, by Andrew Boland, is a little girl who sadistically kills many people through the course of the story.
 * Josephine in Agatha Christie's Crooked House.
 * Gwendolen Chant from Diana Wynne Jones' Chrestomanci series may look like a china doll, but for her vindictive nature and her mistreatment of her brother Cat.
 * Peter Wiggin in Orson Scott Card's Ender's Game liked to torture animals to death and physically and mentally torment his siblings.
 * The murderous newborn in Ray Bradbury's short story "Small Assassin" personifies the concept.
 * The disturbingly polite and sweet children in "The Veldt", who murder their parents because they've threatened to cut off TV their holographic nursery also count, of course. Bonus points for being named Peter and Wendy.
 * An even creepier example would be "Zero Hour", in which every child in the world is convinced by an alien race to set things up to let them invade Earth and kill all of the adults. And they agree because they are promised later bedtimes, no baths, and all the TV they want.
 * Clark Fries in Robert A. Heinlein's Podkayne of Mars.
 * Amity Adora ("Amma") Crellin in Gillian Flynn's Sharp Objects; charming, childlike, spoiled, vicious, manipulative, morbid, sexually precocious, and, incidentally, by the age of thirteen.
 * Redwall's Veil Sixclaw. He's an Exclusively Evil ferret, who ends up being raised by the good mice. From the start he makes them suspicious, hence the name they choose for him. His foster-mother Bryony puts it down to fear of Carnivore Confusion and adores him, but by his teens he's attempting to poison fellow Abbeydwellers. Some fans who see him as the Woobie forget that he continues this behaviour in his wanderings, committing highway robbery and murdering two foxes (who admittedly had captured him earlier). He apparently gets his psychotic tendencies and grudge-holding abilities from his father.
 * What really mixes up this example is the fact that he  This has the effect of convincing Bryony that he really was evil in his heart all along (it doesn't make sense in context either).
 * Tara Webster, Michael's little sister from Goosebumps book - The Cuckoo Clock of Doom - appears to gain a sadistic pleasure from making her brother's life difficult, and displays no redeeming qualities at all. It appears that she's always been like this, to the point that she would make things difficult for her brother even when she could barely speak.
 * Coin, from Sourcery, seems a lot like this.
 * Coin wasn't psychotic as much as he was just a naive kid guided by bad parenting. He did hesitate from because he was harmless, and when he later  he begins to realize that killing people isn't right.
 * And the Ass Saw the Angel (a book written by Nick Cave, whose musical career provides the page quote) has the character of Beth. The Unreliable Narrator can't quite make up his mind whether she's actually a demonic witch or not.
 * Tad Williams' The War of the Flowers just straight out calls it The Terrible Child. Everyone knows he's pure evil though. That was kind of the point of creating him in fact.

 * Euphemia in My Godawful Life, a parody of Misery Lit: a foul mouthed girl genius who turned her former foster parents into spiders and who has driven many of her carers to suicide. She also hints that she fakes her Asperger's Syndrome in order to avoid being locked away, and may have murdered her father (a paedophile) and his friends.
 * Markie, a toddler who makes life miserable for Skeeve and his associates.
 * The protagonist of The Wasp Factory by Iain Banks is a 16 year old boy who has killed three children and numerous small animals, the children at a very young age.
 * Haunted:
 * Some of the Desinger Baby Sex Slaves in Miriam "Starhawk" Simos's The Fifth Sacred Thing.
 * Mordred Deschain, The Little Red King, from The Dark Tower series. At least two characters fall victim to this evil baby within hours of his birth.
 * In Death:  is revealed to be this in Innocent In Death. She is The Sociopath who killed her own baby brother, two male teachers, an old woman in a nursing home, and also tried to kill her own mother. There is no Freudian Excuse for this child.
 * Leck in Fire/Graceling. Guess it comes with being able to ...but a lot of people are damaged or killed thanks to him.
 * The Bernard Taylor novel The Godsend tells the story of an English family of six who take in an abandoned baby.
 * Palpatine was this well before he met Darth Plagueis.
 * Palpatine was this well before he met Darth Plagueis.

Live-Action TV

 * The various Law & Order series like to play with these, and especially emphasizes the handwringing "what can we do, the legal system can't handle such a monster without exploiting innocent kids!" response.
 * A notable example in Law & Order is an eight year old girl who has issues with the male gender: she would rip out the eyes out of males in pictures, poisoned a cat just to watch it die (and doesn't flinch when the Psychiatrist yell at her for it), scared her nanny to do her bidding... and murdered a younger boy and stuffed a battery in his mouth. And of course doesn't have, and likely is completely incapable of feeling, a shred of remorse.
 * There was also a Law and Order Special Victims Unit episode with a kid who murdered another one and mutilated himself to scare other kids. When it was realized he wouldn't get charged as an adult
 * Interestingly enough,
 * There's also another episode of SVU which revolved around a harassed boy that gunned down members of the school's basketball team, then tried to commit suicide and missed then blamed an alter ego named "Zoltar" for it. He gets better though, as the unit gives him the opportunity to go to a mental hospital to cure his disorder.
 * Another episode of SVU looks like it is playing this trope straight (kid comes to school and shoots another kid on the playground) but it is actually subverted (he was shooting at the gangsters behind the fence that have been threatening him).
 * CSI had Hannah West, a 12-year-old child prodigy who successfully got her brother released by  and then turned into a Yandere when her brother paid more attention to his girlfriend than to her.
 * Then there were the little bundles of horror that were the killers in "Bad Words" and "Cats in the Cradle." The killer in "Go To Hell" also had an early-teens accomplice who was arguably an even worse person than he was. Oddly enough, subverted with the killer in "Gentle Gentle," the actual youngest perp seen on the show... who was too young to know what he was doing.
 * Let's not forget the role played by- sigh- Justin Bieber as Jason McCann. This may be one of the WORSE ones on this list even though he's sort of a Girly Boy because instead of sadistic sadism, he cunningly plans,, and does this all by It is however worth it in the end when
 * The Anointed One in Buffy the Vampire Slayer.
 * Also from Buffy the Vampire Slayer are Hansel and Gretel, a single demon that takes the form of two dead (and later living) children apparently murdered by occult forces to cause the mothers of Sunnydale to try to kill all the other supernatural elements. Under their influence, Buffy's mom, Willow's mom, and several others attempt to burn Buffy, Willow, and Amy at the stake. It doesn't work so well when Hansel and Gretel are turned back into a big ugly demon though. Apparently the original story of Hansel and Gretel was based upon an earlier more successful attempt by the same demon in Germany.
 * Angel had an episode where a little boy was possessed by a demon and doing horrible things. They exorcise the demon, but find out from the demon (who begged to be killed) that it was the boy himself who was so evil, and that the demon had been trapped.
 * To be fair, the demon would have done the same kinds of things if it had been in control. What had him scared was that while demons like him do evil things for the love of evil, the boy was utterly cold inside when he did things like try to kill his own sister.
 * Really even saying he was cold inside is giving the kid too much credit based on what the demon said. The demon described it as being trapped inside a total emptiness and that even though he had been corrupting humans since "before [they] had words to name [him]", it was the darkest thing he had ever known, driving him to take control of the boy's body at night to attempt suicide.
 * Chuck in several episodes of iCarly.
 * A side-effect to cloning a little girl in Smallville happens to be the negation of any sense of right and wrong. Another side effect is super speed which makes Lana think she's a ghost.
 * The clone twins Teena and Cindy, in The X-Files episode "Eve".
 * The X-Files also gave us Charlie from "The Calusari."
 * The Millennium episode "Monster" concerns a demonic lil' tyke who frames her daycare provider for abuse, then does the same to Frank when he investigates.
 * There are at least two examples in Doctor Who. In Remembrance of the Daleks, a girl is possessed by the Dalek battle computer. In "Human Nature" and "The Family of Blood", another girl is overwhelmed by the gaseous entity 'Sister of Mine', taking over her lifespan. The same musical theme in both cases.
 * The trope is also toyed with in "Closing Time". The Doctor, who claims to be able to speak baby, tells Craig that his infant son Alfy prefers to be called "Stormageddon, Dark Lord of All." There's no indication that he's an actual evil baby, though.
 * In The Celestial Toymaker, Cyril is what Billy Bunter would be if he were a Psychopathic Manchild's slave. He crosses the Moral Event Horizon in episode 4 when . However,.
 * Supernatural has just picked up one of these.
 * It also had one as a Monster of the Week way back in Season 1;
 * Supernatural loves this trope. Enfant Terribles, usually ghosts, possessed or just plain crazy, turn up in Dead in the Water, The Benders, Playthings, All Hell Breaks Loose, The Kids Are Alright, Bedtime Stories, Are You There, God? It's Me, Dean Winchester and Family Remains. Did I miss any?
 * In The Real Ghostbusters Fritz actually complains about how often this happens, right before an attack by three more evil ghost kids.
 * Little sister Megan on Drake and Josh is an evil, conniving brat to the titular characters, but acts sweet and adorable to everyone else.
 * Brat doesn't really cover it. She's a pre-teen super villain. She's got a hidden high-tech lair in her bedroom disguised as girly toys and pictures. Seriously.
 * Madison in the The Inside episode "Everything Nice"
 * The first episode of the Eleventh Hour features
 * Hannah Montana has Rico. He has the makings of an Evil Genius.
 * Parodied in Only Fools and Horses—Rodney is convinced that his nephew Damien (the name is not coincidental) is one of these, and acts as if he's with the Anti-Christ anytime he's in the same room as him. Of course, the boy's just a normal child, but try telling Rodney that.
 * One particular scene highlights this; Damien wants to show off a conjuring trick he's learnt, and chooses Rodney to show it to. From Damien's point of view, he's just happily playing with his uncle. Rodney, however, looks as if he's being forced to participate in some kind of satanic ritual.
 * From the episode "It's a Good Life": "No comment here, no comment at all. We only wanted to introduce you to one of our very special citizens, little Anthony Fremont, age 6, who lives in a village called Peaksville in a place that used to be Ohio. And if by some strange chance you should run across him, you had best think only good thoughts. Anything less than that is handled at your own risk, because if you do meet Anthony you can be sure of one thing: you have entered The Twilight Zone."
 * He in turn is parodied in an episode of Johnny Bravo.
 * The sequel episode gives us Anthony's daughter Audrey, who seems better than he is (she openly admits to hating him when she sends her friend's father to the cornfield) but towards the end of the episode
 * In A Nice Place to Visit, Rocky had led a street gang while in grade school.
 * In Desperate Housewives, Kayla, Tom Scavo's illegitimate daughter became, this. At first she was just cold to Lynette, who her conniving mother Nora had told her wanted to take her (Kayla) away from her (Nora), which was true, but only to get her away from Nora's crazy. But then the next season, Kayla does increasingly outrageous things, from convincing her half-brothers to jump off the roof to claiming Lynette abuses her, all in the name of getting Lynette out of the picture so she could stay with her father.
 * Mordred in Merlin used to just be creepy, but now he's a ruthless killer who doesn't even blink.
 * Similarly, in the 1998 series of the same name, the first thing we see of Mordred is him, as a young toddler, picking up a knife and throwing it across the room at a guest. According to his mother, it's just his way of demanding attention.
 * Criminal Minds
 * In the episode "The Boogeyman" it's revealed the killer was a twelve year-old boy who would lure other children into the woods, then beat them to death with an aluminum baseball bat.
 * "A Shade of Gray" reveals the (main) killer was a child sociopath who had murdered his younger brother by cramming model plane parts down his throat after his younger brother broke the model plane by accident. He also killed the family's puppy.
 * The episode "Safe Haven" had a 13-year old sociopath on a cross-country killing spree, slaughtering entire families by gaining their trust with his seeming innocence in order to get access to their homes.
 * In Power Rangers Operation Overdrive (made and taking place in 2007), Thrax, son of Rita and Zedd, spent a few days as The Man Behind the Man in charge of that season's warring factions, and proved a villain powerful and skilled enough to disable the entire incumbent Ranger team. Word of God says he was born between Zeo and Turbo (that's the reason Zedd and Rita didn't take Big Badhood back like the Zeo finale implied they would, they were raising him), making him just ten years old at the time.
 * Alexander from Smallville. Given that he's a clone of Lex Luthor, this shouldn't be surprising.
 * Malcolm in the Middle has a few: Francis, the eldest, did several horrible things as a toddler, and ended up lighting his teddy bear on fire (and the fact that he poured lighter fluid on it implies that it was deliberate), and it is heavily implied that Francis' final action was the reason why Lois ended up having to become such a strict mother. Reese kicked his mother hard enough to force her to go into labor several hours before the scheduled time for labor, and then kicked the doctor as he was born. Probably the worst offender was Jamie, who after being born, often frames his brothers for things he did, and when under the influence of soda, actually attempts to murder Lois by shoving a shelf onto her. Suffice to say, Francis and Reese really don't grow to become any saner into adulthood.
 * The apparent physical age of immortals from Highlander is fixed at the age of their first death; two episodes featured an evil immortal who had undergone this at seven years of age.
 * The apparent physical age of immortals from Highlander is fixed at the age of their first death; two episodes featured an evil immortal who had undergone this at seven years of age.

Music
"Since I was no bigger than a weevil They've been saying I was evil That if bad was a boot then I'd fit it That I'm a wicked young lady but I've been trying hard lately Aw, fuck it. I'm a monster, I admit it."
 * The previous page-quote, "The Curse of Millhaven", by Nick Cave and his aptly-named backup band, The Bad Seeds, is about a 14-year old mass murderer, who drowns the neighbour's kid, burns down property, decapitates the handyman (with the circular saw in his garden shed), stabs an old lady to death, and is directly responsible for an entire class of children drowning, but did not Crucify the Dog. Nothing odd about the mass murdering, especially on an album like Murder Ballads, but it just goes to show- even a cute, blonde-haired small town girl can be evil to the core.

"We've got a sense of humor but we haven't any cares. Oh how I had to laugh when we kicked granny down the stairs. On our tippy-toes we crept right up where she was standing, And the tears ran down my face as she lay bleeding on the landing. And when we called out "Mama! Quick! We think our granny's dying!" And when Mama came a-running we pretended to be crying. We said "We saw her trip"; they couldn't tell that we were lying And since Granny was unconscious she was doing no denying! Ha Ha Ha Ha Ha Ha Ha Ha Ha Ha Ha Ha Ha."
 * Not to mention the band references two earlier examples: Nick Cave and the Bad Seeds have an album called "The Good Son".
 * Independent L.A.-based band Creature Feature has a song called "Such Horrible Things," which follows the birth, life, various horrors, and final institutionalization of an unnamed psychotic individual, who's deeds include, but aren't limited to:
 * Pouring super glue into his father's hair at the age of two.
 * Attempting to leave a "friend" in the woods to die at age six.
 * Burning down his family's house at the age of eight because he hated the color of the place.
 * And at fourteen "there was that one time" which, on the actual song, is conveyed only by a musical interlude and lots of screaming.
 * Edge of Sanity's "Crimson II" is about a demonic child born to a nun who read a cursed book. The child can read minds and kill victims by projecting "images too hideous for human minds to bear".
 * Cruella de Ville's song "Those Two Dreadful Children" details an allied pair of Enfants Terribles:

"The cat is dead, the cat is dead, And Mikey too, and Uncle Fred Expiring oh so suddenly while Sipping down some tea. The tea was hot, the tea was nice With strychnine and a little spice To cover up the funny taste Of our conspiracy. When Grandpa saw what we had done He went straight for his hunting gun. But we were quick, we stole the clip; The rest is history. To make sure Grandma wouldn't flee We gave her a lobotomy And now she's just as happy as can be."
 * And to top that, "The Cat Is Dead" by The Mystic Knights of the Oingo Boingo (the predecessor group to the better-known Oingo Boingo), gleefully delineates the actions of a trio of psychopathic children:

"About a maid I'll sing a song, Sing rickety-tickety-tin, About a maid I'll sing a song Who didn't have her family long. Not only did she do them wrong, She did ev'ryone of them in, them in, She did ev'ryone of them in."
 * And also, of course, Tom Lehrer's "The Irish Ballad."

"Just take a look, ah, that's my lad. Why, I'm in Heaven when he calls me "Dad". He's all in life I'll ever desire. See how cute, he sets the mailman on fire! Little rascal, with his tousled hair, Always seems so full of life. Tiny footsteps, scampering here and there. Just see how proudly he carries that knife! When he's not giving Daddy a hug, You'll find him pouring acid on the rug. Cute! He's just an angel with an axe for a toy. Ha ha, that's my boy!"
 * "That's My Boy" by Stan Freberg:

"Now the day I was born The nurses all gathered 'round And they gazed in wide wonder At the joy they had found The head nurse spoke up Said, "Leave this one alone" She could tell right away That I was bad to the bone."
 * "Excitable Boy" by Warren Zevon describes a young man who is probably just on the verge of growing out of this trope and into a full-grown adult psychopath.
 * The first stanza of "Bad to the Bone" by George Thorogood and the Destroyers:

Oral Tradition, Myths, Legends and Folklore

 * Older Than Feudalism: the Greeks had Zeus, whose mother saved him from being eaten by his father Cronos (trying to avoid Karmic Death for overthrowing his father); Zeus then served up some nasty poison to Cronos while posing as a servant; his son Hermes tops this by stealing a herd of Apollo's cattle almost as soon as he was born and then sweet-talking his way out of being punished for said theft (and, on top of that, killing one of the cattle as a sacrifice to himself).
 * The Chinese god of battles Ne Zha (pronounced Nataku in Japan) not only was born in an egg-like sac that took three years to "hatch" (finally Dad got fed up and attacked the thing with a sword, after which Ne Zha burst out), he also brought the wrath of the Sea King down on him when he accidentally killed a young prince when said prince went topside to give him grief about his destructive playing habits.

Radio
"Do you think I'll be the best torturer in the world? Do you think my father will be proud of me? WELL? WILL MY DADDY BE PROUD?"
 * The Holy Terror from the Big Finish Doctor Who audio of the same name. The child in question is a five year-old boy who has been imprisoned in a dungeon ever since he was born so he would grow up untainted by the world, divine and all powerful. Oh, he's all powerful alright.

Tabletop Games

 * In World of Darkness: Innocents, where the player characters are children, a character who hits zero on the Karma Meter becomes one of these. They aren't necessarily evil, but they have absolutely no empathy or conscience. As the book puts it, they'll probably end up institutionalized.
 * The New World of Darkness game Changeling: The Lost includes Fetchspawn, one of the options for the children of the fake people that the Gentry leave to replace Changelings. They have no Karma Meter. They have no empathy. Most people just assume they're autistic because of their total inability to relate to other human beings on an emotional or social level. They tend to kill things just because. This is all exacerbated by the fact that their touch automatically opens all doors, springs all locks, they cannot be bound or imprisoned, and people tend to ignore them, so they're able to slip around without notice. They are immune to Changeling superpowers, and their touch drains the Lost of magical energies. Oh...and did we mention that at the age of 21 they get sucked back into the Hedge, likely to become Gentry themselves?
 * In Mage: The Ascension, widderslaint were reincarnated Nephandi (mages who were evil because of their malformed souls, or whose souls were malformed by their evil). Even before their awakening as mages, they're irredeemably evil (the fiction introducing them describes an infant crawling into his twin brother's crib to strangle him to death, then falling asleep hugging the corpse like a teddy bear).
 * The Dungeons & Dragons 3.5 manual Heroes of Horror, incidentally, introduces a template called Unholy Scion, which is basically a creature whose soul has been substituted with a demonic/devilish/evil essence while still in the womb. Already at birth, the resulting child is a fully-sentient Complete Monster who holds his/her/its own mother in thrall through evil power alone, and gains terribly destructive powers as it grows in Hit Dice. Oh, and did I mention it is so evil that its merest touch can grievously harm good-aligned characters?
 * There is a sequel to Cyberpunk 2020 called Cyber Generation, where the Edgerunners of CP2020 have mostly been either killed or grown complacent by buying cushy corpjobs with retirement, leaving the rebellion to their children. It's very possible to play this kind of character in this game, especially if your character is a type of YoGanger referred as a Beaver Brat. Beaver Brats mostly come from suburban areas and specialize in talking their way out of trouble by convincing adults that there has been a big misunderstanding and they couldn't possibly have done it.

Theater

 * Mary Tilford from The Children's Hour is a malicious girl who tells a lie about her two teachers just to get out of going to school. She then blackmails another girl into saying she started the lie, pull's the other girl's arm out of her socket (albeit accidentally), and steals several jewelries.

Video Games
"M. Bison: OF COURSE!"
 * Bulleta/B.B. Hood from the Vampire/Darkstalkers series is a borderline example, as although she appears to fit it perfectly, it's sometimes implied that she's much older than she appears.
 * Played totally straight in Metal Gear Solid: Portable Ops, with a very, very deadly child soldier known as The Frank Hunter to the mercenary community, because of his habit of approaching his targets with nothing except a knife and an innocent cuteness that made it impossible for them to strike back.
 * More implied, but equally straight, the same series brings in a government cloning project to develop exceptionally gifted children who could be raised into brilliant soldiers - this project created the main character and two Big Bads. The name of the project? 'Les Enfants Terribles'. It's not an example of this trope at the time the series takes place, though, because the trouble starts when the Enfants are all well into their thirties. We'll have to hope for Metal Gear Kids.
 * Done.
 * How young are we talking?
 * Actually, Liquid might come very close to this trope, assuming the Official Missions Handbook's claim that Liquid participated as a mercenary at the age of 13 is canon. In either case, Solidus comes the closest, seeing how he was implied to have led a unit in the Liberian Civil War as a teenager (although in his case, pretty much everyone wasn't an adult).
 * Don't forget Raiden, who was raised to be a child soldier after his parents were murdered by Solidus, and placed in a unit of young boys that fought in the Liberian civil war. His nicknames were 'Jack the Ripper' and 'White Devil'.
 * The villain in Drakengard, the megalomaniacal empress and feared high priestess of the Cult of the Watchers...is a little blonde girl about six years old. She seems to be floating in the air without a care as far as her mental state goes when you first meet her, but then she speaks. And her voice has this odd habit of alternating between a cute girl's and an evil man's. Her eyes are also naturally blood red, which is just disturbing.
 * Arcana Heart has two:
 * Kira Daidouji, an 11-year old child genius who got fed up with having to return to Japan to mix in with the "normal kids". Her research on ether science has allowed her to create a large watery blob, whose body she uses for combat. Sounds normal at first, but when you consider she also wants to use that blob to help her Take Over the World, you're in completely different territory.


 * Lieselotte Achenbach is a ten-year-old assassin who carries around the spirit of her dead older sister in a puppet with no legs. Creepy!
 * Independent adventure game Emily Enough features this as the player character: Emily decides, at her birthday, to slaughter her family. The rest of the game features her trying to get out of the asylum she ends up in. Emily herself seems quite comfortable with her new profession, too.
 * Occurs occasionally in Super Robot Wars, but most prominent with the leader of the Inspectors: Wendolo. Killed his own brother and threw away his Quirky Miniboss Squad without shedding a tear, felt no shame in desiring to enslave humanity and reduce them to mindless killing machines (Incidentally the exact same plan as that of the Balmarians, who were the sworn enemy of the Inspectors' superiors), refer to humanity as nothing more than a cancer that needed to be eradicated, and doing it all with a smug grin on his face.
 * By far, the absolute worst example on this list is Betty, of Fallout 3. She's the mistress of a Lotus Eater Machine that would be a utopia, if it wasn't for the fact that she likes to sadistically torture people to relieve boredom. And she forces you to help her.
 * Betty is a bit of an aversion as she is actually
 * In the same quest (and the entire game with a proper console code/mod) you can be one yourself. The biggest example perhaps being to kill Timmy's parents, and then brag to him about it.
 * There's also the in-world, pre-war Urban Legend of the "Pint-Sized Slasher" An unknown kid in a clown mask with a kitchen knife, going around killing adults. Whether he exists or not is up for debate, but Betty (Mentioned above) uses the legend for her own twisted enjoyment while you are in Tranquility Lane. You can find what is supposed to be the Pint-Sized Slasher's mask in the Point Lookout expansion (In two locations, no less!)
 * Flandre Scarlet from Touhou. One of her main gripes is that whoever she tries to play with, except for other uberpowered Big Bads and main characters, tends to end up a splatter in the wall.
 * Flandre is really 495+ years old. But she pretty much has a child's mentality.
 * Thief: Deadly Shadows arguably fits the trope with although since she's actually  it may be an "in name only" example.
 * Kohaku of Tsukihime looks like a sweet Meido who wants nothing more than to please her master. Then you peel away the layers of Stepford Smiler and find a Yandere with a deep, deep grudge against the Tohno family. (By the way, she's been slipping suspicious substances in the Protagonist's food the moment he stepped foot into the mansion and he can end up as the subject of her sadistic experiments by accident.)
 * The Cherubs from Doom 3.
 * Overlord II's Witch-boy would be this, if he were cute to begin with. At best he's sort of Ugly Cute... At least to Kelda.
 * In Jump Start Adventures 3rd Grade: Mystery Mountain, the villainess is the Spoiled Brat daughter of a great Professor—basically, Veruca Salt with access to buttons that can destroy the world.
 * In the Total War series, one of the entourage members an assassin can get is an apprentice. The flavour text basically describes this trope.
 * in Rule of Rose isn't pure evil, but
 * In Dead Space, we have Lurkers, though they actually qualify more as Fetus Terrible. In Dead Space 2, we have those, plus Crawlers (instead of fetuses, these are babies old enough to crawl...and they have an exploding sac on them) and The Pack (Bratty zombie kids...they don't have body-part weapons like most other necromorphs do, but they are fast and always attack in groups)

Web Comics

 * Ruby Gem in Monsterful: She's plain open evil, specially with her mother Diamond. On recent chapters her evilness has evolved to the point of sacrificing virgins and wanting to gut her teacher like a fish.
 * On the Monsterful 2010 Xmas Special,
 * The catgirls in the Something*Positive arc "Kawaii of the Damned".
 * Parodied in Charby the Vampirate.
 * The Onion Kid is mistaken for this after the deaths of his family and several foster families afterward.
 * BM might have been one of them but we don't know if he was cute (we can guess he was not though)
 * Millie from Ozy and Millie.
 * Megaweapon from Far Out There certainly acts the part (and the things we only hear about are even worse).
 * Slippery Weasel of Frog Raccoon Strawberry is an incredibly evil wizard who is still in diapers.

Web Original

 * In The Gamers Alliance, both Arawn and Yurius were truly horrible even when they were still young. Yurius gleefully set people on fire, and Arawn massacred his foster family as well as plenty of other people who annoyed him but still had the nerve to act totally innocent in order to fool the mages investigating the murders.
 * Most users on YouTube. They just upload harmful videos, write nasty comments and insult each other, even at the teenage.
 * Survival of the Fittest's answer to this trope is Kimmy Redmond, a girl who has the look of somebody five years her junior, complete with carrying a lollipop around. A unicorn lollipop. She also has very few compunctions about causing harm to her classmates. Although it hasn't happened yet, it's very likely this will transfer to killing them too.
 * A more accurate example of this trope is 12-year-old prodigy Brandon Cuthbert, who, before the game, sliced up various woodland creatures for experiments. This carries over to when he He seems to show some remorse for his actions right before  though.
 * Vendetta from Making Fiends isn't particularly cute, nor is she a Devil in Plain Sight, but BOY is she sociopathic.
 * As part of the Dr. Horrible's Sing-Along Blog DVD release, "L'enfant Terrible" was one of the chosen winners for the Evil League of Evil Application contest. The application video can be seen here.
 * She's smarter than you.
 * Open Blue features Remillia, which deploys Tyke Bomb special forces known as Angels. They begin active duty at the age of 13, and the younger ones tend to use their age to fool targets of their assassinations. Senseless Violins are just one of their many weapons.
 * By all appearances,  and   look cute. Too bad that in There Will Be Brawl,
 * The Mwa Mwa Penguins you can find at the Pet Shop in Club Penguin embody this trope.
 * Within the world of Magical Girl Hunters, some of the magical girls joined to save the world. Some just like the excuse to kill stuff. Captain Kawaii... * shudder*
 * The webcomic / video series Contemplating Reiko stars the daughter of Satan and her three older sisters.
 * Many/most of the kids from Childrin R Skary fit this.

Western Animation
"Butters: "Society cast me out, and so I vowed to make them all pay! And pay they did! Nobody knows that beneath this sweet eight-year-old little boy lies the most evil, the most destructive supervillain of all time!""
 * Professor Princess from Transformers Animated dresses and acts like a young girl but has a psychotic obsession with destroying 'violent' toys, in one instance deactivating Angry Archer's explosive arrows because they were too destructive. However, she uses a wand-like item that destroys things in a blast of sparkles and flowers. Apparently if there's flowers it's okay.
 * Stewie Griffin from Family Guy is a comedy example; he's a sarcastic, ranting evil genius with a homicidal grudge against his mother, and he's only one year old.
 * Maybe Eliza Pinchley. Vowed to viciously kill Lois and meant every single word... She hasn't actually attempted it, though, and her character will probably never return to Family Guy.
 * Also Bertram, who in his most recent appearance has become an Omnicidal Maniac.
 * In Batman: The Animated Series, Baby Doll is a washed up actress with a bizarre debilitating condition that makes her look permanently like a child regardless of her age. The fact that no one takes her seriously as an adult ruins her life and she becomes insanely fixated on the mannerisms and environment of her one successful role.
 * Therapy can help, and she's actually pretty nice when she's not crazy. She just has a BIG Berserk Button.
 * This video featuring her pretty much shows what the Enfant Terrible is all about.
 * Wendy Testaburger from South Park, in the episode "Tom's Rhinoplasty", where she gets hot substitute teacher Ms. Ellen shot into the Sun by Iraqis in a fit of jealousy.
 * Don't forget Cartman, the racist, bigoted, murderous, self-centered Heroic Sociopath. While his attempts at being cute aren't always very successful, he is still without a doubt, the most manipulative character in the show and is quite psychopathic.
 * Most of the younger characters, now and again. Let us not forget Professor Chaos! Bringer of destruction and Doom!


 * Mandy from The Grim Adventures of Billy & Mandy, despite having a Deadpan Snarker and Emotionless Girl personality, is young enough and psychopathic enough to qualify.
 * She is in fact, the Goddess of Enfantes Terrible.
 * All of the main cast in Lil' Bush. Then again, they're Strawman Political Spinoff Babies based on real politicians.
 * Darla Dimple from Cats Don't Dance is a psychotic (and sometimes Genre Savvy) child actress.
 * 3-year-old Angelica Pickles, of Rugrats, is mean to the babies but sweetness and light to the adults. By the time of All Grown Up!, set 10 years later, she is less able to get away with this.
 * Then there's her dreamed up baby brother of Nightmare Fuel, that for the sake of identification will be called Drewie. I'm glad that hell baby wasn't a real Rugrats character.
 * Bart's evil conjoined twin Hugo in a The Simpsons Treehouse of Horror episode: "A routine soul smear revealed the presence of pure evil."
 * Maggie might also qualify.
 * A young princess Azula (as seen in flashbacks) from Avatar: The Last Airbender skillfully combines an angelic smile with both Creepy Child and Enfant Terrible behaviour.
 * Ben10 had Ben's Evil Counterpart, 11-year-old sociopath Kevin 11, who was willing to kill hundreds of innocent civilians as part of a heist attempt in his first appearance (all previous villains on the show had fairly standard Saturday Morning Supervillain plots, Kevin's was the first to really be over the line by Ben's standards) and just got crazier from there. Unlike most examples of this trope, Kevin actually grew out of it in the sequel series.
 * Suzy Johnson, Jeremy's little sister on Phineas and Ferb, acts sweet and innocent in the eyes of her brother, but when she crosses paths with his girlfriend, Candace, she shows her True Colors when Jeremy isn't looking.
 * She is also apparently the most horrible thing in the world to Buford, the local bully, who all the other kids fear.
 * Charles aka Brainchild from The Tick (animation), a ludicrously intelligent kid (he mastered quantum physics before he could walk, among other things) whose desire to become a Card-Carrying Villain is met with benign acceptance by his hippie family.
 * Heloise in Jimmy Two-Shoes. She's a small girl who works in Misery Inc. as top inventor to create dangerous products for misery and she loves to destroy stuff. She is also easily angered and hates nearly everyone but the titular character.
 * Codename: Kids Next Door:
 * Obviously, The Delightful Children from Down the Lane. A common joke in fan fiction is to compare them to the Children of the Corn, which gives you a general idea what they're like. Not only have they attempted to kill the main characters, they reached a whole new level of creepy in season four when they were going to eat a cake made from other children
 * Joey, Numbah Four's baby brother, specifically in the episode "Operation: DODGEBALL". While he is on the good guy's side, challenging and defeating the evil Dodgeball Wizard, he's pretty brutal when doing so, beating the villain to a pulp and wrecking an entire city in the process.
 * Ren Hoek of The Ren and Stimpy Show was portrayed as one of these in the Adult Party Cartoon episode "Ren Seeks Help". As a child, he was playing innocent to his parents, but without supervision he is shown commiting acts of vandalism such as setting fire to buildings and torturing and killing animals. He gets away with it, until one of his victims (a frog) tells his parents about what he's been doing. After some lecturing on the horrible things he's done, they tell him the only thing he can do for the frog is put it out of it's misery - rather than do this, he chooses to let the frog go and suffer more, leading to its eventual suicide.
 * Foop on The Fairly OddParents is basically a magical G-Rated version of Stewie.
 * The Boondocks episode "Smokin' with Cigarettes" featured Lamilton Taeshawn, a psychotic young boy from a broken family who lived with his grandmother. He claimed he did terrible things, not for sympathetic reasons, but because he liked to cause people to crash in their cars, break people's arms, and assault elderly people including his grandmother. He killed a dog and later attempted to kill Riley when Riley told him he didn't want to friends anymore.
 * The character of Lamilton was based on a boy named Latarian Milton, who stole his grandmother's car at the tender age of seven. When asked why, he responded "I want to do it because it’s fun. It’s fun to do bad things. I wanted to do hoodrat stuff with my friends," one of whom "smokes with cigarettes". The next month, young Latarian was back in the news—for beating up the same grandmother in Wal-Mart because she wouldn't buy him chicken wings. He was subsequently 5150ed.
 * An episode of Nightmare Ned had a a doll-sized Ned being tormented by a pair of twins.
 * Sarah from Ed, Edd 'n' Eddy, Ed's little sister. She enjoys beating up the whole main trio, especially Eddy, who are all older than her and boys, for goodness' sake. Normally, she wears a facade that makes her looks sweet and nice, but she very often uses the argument of "telling mom" (and others, which include her attempting to suffocate herself) to manipulate Ed.
 * The Caterpillar Room kids from Toy Story 3, or at least how the toys there see them.
 * Cousin Eddy from Jimmy Neutron fits this trope to a T, not to mention is only one years old.
 * The Powerpuff Girls.
 * Princess Morebucks A capitalist bully.
 * Mitch from the episode "Getting Twiggy With It", a cruel school bully who volunteered to take care of Twiggy (the class' pet hamster) simply so he could torture it; after his abuse caused Twiggy to mutate into a giant hamster, the Girls actually wanted to let Twiggy eat him.
 * Porky Pig's toddler charge in the WW 2-era cartoon Brother Brat. The kid's mom (a welder at Lockheed who leaves the kid for Porky to babysit) gives Porky a manual on child care. At the end of the cartoon mom shows Porky how to use the manual correctly.
 * From The Flintstone Kids; Captain Caveman's Arch Nemesis Mr. Bad is an adult, but as the hero relates to his son - via Flashback - the villain's criminal career started in elementary school, where he took over the school with homemade Mecha Mooks.
 * Hector Con Carne, the Villain Protagonist of Evil Con Carne, is another villain whose career as such started as a child. Flashbacks show that the first land he conquered was the playground at his kindergarten and he also kidnapped other students' pets and toys, holding them for ransom.

Real Life

 * School bullies, of course.
 * Jesse Pomeroy, the youngest person in Massachusetts convicted of murder in the first degree, at the age of 14.
 * Mary Bell convicted of strangling two young boys in 1968 at the precious age of 11 (pictured here). She was rehabilitated, and is still alive.
 * Willie Bosket, whose crimes, starting at the age of fifteen, led to a change in New York state law, allowing juveniles as young as thirteen to be tried in adult court for murder and face the same penalties. He is still in prison, not scheduled for release until 2046.
 * Nevada-tan, a.k.a. "Girl A".
 * Jon Venables and Robert Thompson, both ten years old when they murdered two year old James Bulger.
 * The Young Killers articles in the TruTv Crime Library covers several of the above... and more.
 * Cracked.com's 5 Shockingly Evil Things Babies Are Capable Of makes a tongue-in-cheek claim that all babies are natural sociopaths. Most people outgrow these troubling behaviors. Others, like those listed above, obviously didn't.
 * Julia Drusilla, daughter of the original Caligula. Her vicious temper was what made him believe she was really his; she had a habit of savagely attacking her playmates. Murdered at the age of two after her father was assassinated.
 * Then again, she is the daughter of Caligula, and knowing that it was a sport among early historians to apply either Villain or Hero Upgrades to the historical figures they liked or not, it's not clear if Julia was or not as ultra super bad as they say. And she certainly didn't deserve to be beaten to death by adult soldiers, thank you.
 * Jordan Brown, who was eleven years old when he murdered his father's fiancee. His motive? The victim was pregnant, and Brown was afraid the new sibling would turn him into The Unfavorite.
 * Christopher Pittman murdered his grandparents in 2001 at the tender age of 12. According to his legal defense, Pittman committed the murders because the prescription drug Zoloft had made him psychotic.
