Like the title says. Who's voice do you hear when read the comics? I speak for everyone when I say Kevin Conroy is the definite voice of Batman. Ditto for Clancy Brown's Lex Luthor Mark Hamill is not only the definite Joker voice, but the defenite Hobgoblin voice as well. I hope Greg Weisman gets him for Spectacular Spiderman. On the Marvel side, I say Josh Keaton has become a good voice for everybody's favorite web-slinger. Cal Dodd is more definite of a Wolverine voice than Steve Blum. However, Steve Blum is a pretty good voice for the Green Goblin.
