Ozzy Osbourne in Brutal Legend
Brutal Legend could quite possibly be the most metal of all video games. In addition to having Tenacious D's Jack Black voice the title character of Eddie Riggs, the game features voice work from Lemmy Kilmister, Rob Halford, Lita Ford, and yes, Ozzy Osbourne.
In Brutal Legend, the player travels the heavy metal fantasy world as the lost roadie Riggs. The rocker must navigate his way through the world using the information he gathers from the people he meets along the way. Osbourne appears in the game as the Guardian of Metal, who helps Riggs upgrade his weaponry. While Osbourne's character appears dark and brooding, he's actually one of the more upbeat characters in the game.
