I'd rather be a werewolf myself but if I had the opportunity I'd take it, I wouldn't even pretend to be one of the nice vampires we normally see these days that seem to like solving crime a lot too. I'd be a walking revenant, sucking the blood of my victims when hungry and maybe snapping a few necks when I'm not. Either that or become a predator that only stalks the toughest prey just like those yellow blooded fellows
Oh, and I'd move to New Orleans too just for stereotypes sake heh.
