Yeah, I don't even remember an episode of TAS with him in it now that I think about it..
He's basically a kid of some rich overbearing parents, who hate the Waynes. He ends up killing both his parents and takes their fortune and continues to run their company into the ground until Wayne enterprise buys it. He then gets struck by lightning and considers that some sort of sign, and carves a mask out of his father's casket.
Jesus. The Batman saga never ceases to amaze with dark characters and tragedy.
Reading that makes me feel like I can invest into this now. Hopefully they pull it off.
Stay dark, cold, and snowing and we got a winner.
