Can you think of a movie where there is a very dark, almost macabre, girl in it?

I am looking for a muse for a character and can't think of any movie where there is a negative, dark, bi-otchy influence upon the story. Someone who is maybe a bit awkward or gross would work too. Just basically someone who doesn't fit the social norms of our society.

There are a lot of good suggestions already listed, but just to go in a different direction:

Lydia Dietz - Beetlejuice
Allison Reynolds - The Breakfast Club
