Joe-bear here with my last character: Vincent Goyle! But, don't bother calling him Vincent, he prefers Harrison or Harris. Anywho, you can check out his bio, but here's the quick list of things you need to know:
+ Witless, not very bright, crude, immature + Follower, not a leader + Very skilled in the Dark Arts, secretly + Speaking of secrets, he's super good at keeping secrets, especially his own beliefs of blood purity + Harris is pretty strong physically. If you need a body guard or to have someone rough others up? He's the guy to go to. + Slytherin's best beater, clearly. Overly aggressive, loves to get rough when the ref ain't lookin, so hold onto your brooms, kids!
Anything else can really be read in his app. Just make sure to never underestimate the ugly kid, he may surprise you yet!
