Check out this awesome voice actor panel from Rose City Comic Con! The voice talent featured were William Salyers (Rigby on Regular Show), Veronica Taylor (Ash Ketchum on Pokemon), Olivia Olson (Marceline on Adventure Time, as well as the voice behind Haven't You Noticed (I'm a Star) ), and of course, Zach Callison (Steven)! With 2/4 of the the voices having made an appearance on SU, we figured this was worth a feature!
