Ahhh, it's hard to decide (I think I'm thinking about this too much)...
Angel and Demon could probably fly, which would be cool. Mecha pilot gets a, well, mecha which would also rock. Seer is cool, you could be all spooky, and a shape shifter would be fun...
But in the end I chose fighter. I always imagine myself as the one who defends the magic user she's loyal to.
... but can I have a giant robot too. *pictures it*
Magic user: Nooooo! I used up all my power, I can't block the next spell!
Bad Guy: Mwahahaha I have you now *Grabs MU's hair and begins long chant*
BG: *gets squished by big metal foot*
Me: My mistress. No touchy!
