i want there to be a survivor where they themselves were a murderer or something like that tbh
a non-human monster would be cool to go against, haven't watched the show, but it just seems like hard to pull off unless it's a freddy or spirit clone.
something that may be cool with it, is the ability to climb and jump, hell maybe remove or greatly decrease terror radius when climbed, their addons including increasing jumping range, climbing speed, how long you can stay climbed, or removing terror radius greatly. basically climb onto a tree or wall, able to peer around the corner, or maybe even enter third person momentarily, and then leap a certain distance. a non-human survivor should mean new ways for the killers to play, not rehashes of the old ones.
