Pokemon maybe?
Pokemon has some of the most darkest and cruelest pokemon. Just check out pokedex entries. Drozee eats the dreams of kids, Hypno kidnaps them, Shedinja steals your soul through its back, Driftloon takes kids to the underworld, Duskull enjoys the sound of crying children, Dusknoir takes people to the underworld, Dusclops takes your soul, Honedge drains the life out of you, Phantump are the result of children who get lost in forests, Gotherita hypnotizes and steals kids to make as friends, and so on.
I can probably keep going on with how many dark things pokemon are capable of, and that's pretty crazy considering this is a game aimed at kids xD
Dance my pretties!
