I was skimming threw the charachter choices and I got some ideas:

Freddy Croughar

A Chef

Scream From "Scream"

A Kid With A Skateboard

Frankenstein

FBI Agent

A guy with no head and the same guy but with a head

If I have any more ideas I will post em here!
Thank You!

The chef and the FBI agent are both excellent ideas.
