Eddie Riggs, voiced by Jack Black, is the ultimate roadie who has been transported to a fantasy world of heavy metal music. He uses his hot rod, known as The Deuce, his heavy metal guitar, Clementine, and an axe with special powers called The Separator to fight the demons of Lord Doviculus. Along the way, Eddie gets help from a few of heavy metal?s greatest stars: Ozzy Osbourne, Lemmy, the bassist from Motorhead, and Rob Halford from Judas Priest. Eddie and his allies gain health by finding statues bound in chains or leather, monuments that play heavy metal songs on the Deuce?s radio and creating pyrotechnics on Clementine. Eddie can also use spells to fly above battlefields to direct attacks or boost the performance of his army with a rally flag.
