post a scary Anime character??

for graphics im going to Design and produce 2 products (souvenirs) to do with my very own ride in a theme park. my ride is going to be related to Anime in some ways, i want scary Anime characters since im doing a scary ride, i need some help for a mood board i have to produce about the ride. Id really want some help with scary Anime pics. and it doesnt have to be Anime if its too tricky, i wouldnt mind Cartoons too. bloody as well as scary would be good too. but then again not too bloody cos some people presumingly will freak out..

sorry for being picky :))
