Liu's alter, and everyone's favorite lecherous lycanthrope. He may be reckless, somewhat callous, and a hormonal idiot, but he's far from heartless. Sully tends to make split-second decisions based on a gut feeling, and this only sometimes works in his favor. He'll fall for, and flirt with, anything with breasts, and primarily uses sexual jokes to get under people's skin. In direct contrast to Liu, Sully is empathetic, wears his heart on his sleeve, and is more than willing to be honest with those he trusts.

Sully's voice sounds very similar to Liu's, just louder and more confident. So, a very typical teenage boy voice.
