-- I didn't put Regan McNiel because she was possessed by a genderless demon called Pazuzu, it was slim pickings and I had to think long and hard to even find good candidates because of the lack of female horror slashers or icons in western horror.... Although in Japan, it's reverse what it is here, they almost always usually have a female killer, whereas in America/Canada/Europe, etc, the killers are almost always men. I did include Sadako and kayako, because they transcended japanese horror and became international icons.. --
