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.

    Hänsel And Gretel - 'Black Lagoon'

    Identical twins with a shared passion for assassination, Hänsel and Gretel make for a fearsome package. Left in the care of an abusive orphanage, the siblings fell victim to exploitation in violent snuff films. Being forced into killing at young ages warped the siblings' personalities to the point they believe they need to kill others in order to live longer.

    Both twins are disturbingly close to each other, even swapping identities for their own amusement. The embodiment of Hänsel uses a battle axe while Gretel wields an immense rifle. If a woods witch befell this version of Hänsel and Gretel, she might want to proceed with caution.

    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.

  • Gaara literally arrives to the world with a Tailed Beast sealed into his body. While this chakra monster granted him incredible abilities that would serve him well in his future career as a ninja, as a child it made him into something of a monster himself. Gaara's birth led to his mother's death, which made his father and his uncle unsympathetic to his needs. When his powers got out of control and he started murdering random villagers, his own father attempted to assassinate him. By the age of 12, violence was all he cared about.

    After fighting Naruto Uzumaki, Gaara puts aside his murderous behavior and uses his abilities more constructively. Despite his change of heart, he was still entirely capable of killing innocent people for most of his childhood.

    Reisuke Houjou - 'Future Diary'

    Despite being a five year old, Reisuke Houjou comes across one of the scariest kids in anime. Like everyone else involved in the Survival Game, Reisuke wants to win, and that means becoming a cold-blooded. His methods far surpass what's possible for most kindergartners, making use of complex chemistry, physics, and social manipulation.

    However, he's not without his childish side - even if he feels hellbent on killing someone, he might show mercy if that person treats him with the kindness he never received from his abusive parents.
