never got that far to hear him, i think i stopped (not because it got boring, but because i got distracted by other things that we're happening in my life, like video games.) after the island where (it's hard to spell his name from memory, ang? something) he met the avatar who was before him. (only voice roles that i know that Mark did was the joker in batman the animated series, batman beyond return of the joker, justice league, the batman arkham game series, and an episode in star wars the clone wars, which the character looked badass, but i don't know which episode he was in)
