Out of all the talented voice actors out there, hands-down, Wayne Grayson is my all-time favorite. His performance on yugioh is absolutely brilliant. Even if Joey were his only role, he'd still be brilliant. As just that one character, he's put on an accent, played 2 personalities (one of which was insanely EVIL) been in love... I could keep going on and on.
I think the most remarkable thing about Grasyon is that all of his roles, both yugioh and other, sound so different. Joey, Shadi, Dartz, Roland, (yugioh) Michaelangelo, (TMNT) Django, (One Piece) Tokegeroh, (Shaman King) and countless others.
