Um...what do you write in a bio, anyway? My name's Peter Pettigrew, but my mates (Moony, Prongs, and Padfoot) call me Wormtail. Bet you'd like to know why, but you can't. Ha.
Anyway... stuff about me? Uh... I'm a sixth year at Hogwarts. I'm in Gryffindor. I have the greatest, most beautiful girlfriend in the world. My best subject is Charms, I guess. I have a rat named Amistad.
Not much else to say. Think I'll go ask James if he wants to run down to the kitchens with me to nick something to eat.
