Crowley, former King of Hell. The Winchesters tried to fix me, but thanks to the incomplete spell I'm now a twisted mess, neither demon nor human.
Though he'll blatantly deny it, Crowley's not the demon he used to be. He puts on a big front, but he's more bark than bite these days. Occasionally he almost seems human.
I would still be wary if I were you.
M!A: Teenager until he gets a kiss from
Castiel.
