post a scary 日本动漫 character??

for graphics im going to 设计 and produce 2 products (souvenirs) to do with my very own ride in a theme park. my ride is going to be related to 日本动漫 in some ways, i want scary 日本动漫 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 日本动漫 pics. and it doesnt have to be 日本动漫 if its too tricky, i wouldnt mind 动画片 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 :))
