Hrm, Grimm to me more seemed like monsters and creatures of destruction that wouldn't really have a place for a succubus - outside of something horrific like flaying a pretty womans skin off and wearing it like an edgar-suit. Which is probably not the sexiest thing one can do.<br/><br/>Mind you i'm fairly pro succubi, just not sure how well they would fit into RWBY where most Grimm have been how to say - 'Dire' animals? Though obviously not following the animal they're based on to the letter. I'm all for adding in such a thing, but im not so sure if it'd work as a Grimm from what we've seen of them.
