Coen the Porcupine

This is a character I made up in a fanfiction I wrote a couple of years back on Gametalk. His name is Coen Dow the porcupine (named after a coendou, a South American(?) porcupine). He's a burly young fighter who specialises in hand-to-hand combat, much like Knuckles, and has just entered his teen years. Unlike Knuckles, however, he tends to get nervous when he's under pressure.
I never did finish that fanfiction though. I couldn't think of a good ending for it. Oh well :/
