Thing is, these "bit parts" are supposed to come from a bunch of different fandoms, and although I have some good ideas, I'm always looking for more. If you wanted to give your characters a true "WTF?!?" moment or some new bit of horror to face, what sort of people/creatures/beasties would you have on your "wandering monsters" list for the game?
My ideas thus far:
The Vorpal Bunny
The Knights Who say Ni
It (as in Stephen King's)
Bake-Neko (Japanese mythology)
Creepy-ass ghosts from movies like Ju-On and Sisters
The "two lovers" sea monster from the Uzumaki manga
A small pack of Velociraptors
Dr. Who (Tom Baker version, with or without a complimentary set of Daleks)
Care to suggest? The sillier/weirder, the better!
