List Rules Vote up the anime children you wouldn't want to run into in a dark alley.

The world of anime boasts no shortage of powerful children, with characters like Sakura Kinomoto and Naruto Uzumaki holding the fate of the world in their adolescent hands. But for all the powerful child heroes of the anime universe there exist deadly anime kids with equally impressive, if dangerous, abilities. Anime never shies away from blessing young people with great power, and just like adults, anime children can let power go to their heads. Unlike the most annoying anime children, many dangerous anime kids actually make compelling character studies.

Many of these kids are dangerous serial killers who easily hold their own against adults. Some possess formidable powers like Mariko Kurama from Elfen Lied, who uses telekinesis to rip apart enemies for fun. Maybe they're blisteringly intelligent like Johan Liebert of Monster, a child nihilist with plans to instigate the apocalypse. No matter what the reason for their brutality, adults are better off staying far, far away from the deadliest anime children.

Raised from birth to be an assassin as part of the Zoldyck assassin clan, 12-year-old Killua Zoldyck sees no problem in murdering anyone who crosses him in the bloodiest ways imaginable. Though capable of brutal violence, Killua can actually be an affectionate, fun-loving kid - until his bloodthirsty side comes out in battle. Due to his pride and loyalty to his friends, Killua will savagely murder anyone who crosses him or his acquaintances, as long as he's sure that he'll win.

If he remains unsure of victory, he avoids the combat, since he doesn't want to endure the humiliation that comes with losing. Armed with a powerful Nen (aura), his metallic yo-yos, and an intellect far beyond his years, Killua is a young force to be reckoned with.

Hibana Daida is listed (or ranked) 2 on the list The 15 Deadliest Anime Children Of All Time

Everyone in the Deadman Wonderland Prison is dangerous in their own way, but Hibana Daida is especially unsettling. At age seven, this girl became an Undertaker, meaning she survived the prison's brutal reform program and ranks as one of the worst and most savage inmates.

When Hibana was in kindergarten, a classmate flipped her skirt. Instead of telling him off or telling the teacher, Hibana reacted by killing not only him, but everyone else in her class. This was, she believed, an appropriate punishment. She also tortured and killed her abusive mother in retaliation for the pain she endured at her hands. In Hibana's eyes, her sadism is just one part of being the "good girl" her mother raised her to be.

Pride is listed (or ranked) 3 on the list The 15 Deadliest Anime Children Of All Time

Although he inhabits the body of a child named Selim Bradley, Pride is actually the oldest homunculus created by Father. In his child form, Selim appears as a sweet, polite little boy who shows respect for his elders. All of his positive traits go right out the window when he turns into the monstrous Pride, a living shadow with rows of sharp teeth. As Pride, he sees himself as superior to humans, torturing and enslaving them for his own amusement. But he targets more than just humans - he also dismembers and consumes Gluttony, a fellow homunculus who was foolish enough to trust him.

Despite his amoral nature, Pride inexplicably enjoys life as a human child, and wishes he could fully inhabit his fake life and make it real. In the end, he manages to do just that.

Mariko Kurama - 'Elfen Lied'

Mariko Kurama - 'Elfen Lie... is listed (or ranked) 4 on the list The 15 Deadliest Anime Children Of All Time
Photo:  Elfen Lied/Arms

After enduring a series of traumatic experiments and complete isolation at the Diclonius Research Institute, Mariko Kurama becomes completely insensitive to the suffering of others. Except when reined in by the threat of being hurt herself, Mariko murders any human being unfortunate enough to approach her, and she delights in fighting and maiming other Diclonius.

Despite her propensity popping someone else's limbs for fun using her telekinetic arms, Mariko remains in many ways a normal five-year-old girl who wants to be close to her family.
