All the kinds of human monsters..?

I'm writing a story about all of the human monsters battle each other to take over the world, but anyways, so far I have: zombies, werewolves, vampires, and mummies. Is there any that I might have missed? I'm talking about like freaks of nature here, not anything like wizards! (although I love, love, love HP) I'm thinking about monsters sort of like Frankinstein but calling them "creepers" like off of Scooby- Doo! Thanks in advance!
