If you don't know the Order of the Stick, go read it NOW. It's an hilarious story of a stick figures party of adventurers in the old fashioned RPG way. Here is Sabine, an evil shapeshifter... for the schoolgirl outfit, you'll have to read the comic, there actually is a reason behind that. Besides the fact that she's dead sexay.
