Skullsmasher has an endless appetite for combat, and for Autobots! He doesn't need blasters or other weapons -- he would rather defeat his enemies by devouring them. He isn't the quietest Decepticon, which can make catching his targets harder. Titan Master Grax makes Skullsmasher invisible to the Autobots by masking his energy signature. When they team up, it's time to chow down.
