As stubborn as he is strong, nothing can stop the brawny Bonecrusher when he charges into battle to crack some skulls! Like a living locomotive with a one-track mind, all he wants to do is fight, fight, fight! Optimus Primal tries to get him to lighten up, if only to prevent him from overheating an internal coolant co-processor, but Bonecrusher would rather be out pounding his enemies into cyber scrap. His favorite attack strategy is to stun opponents with a dizzying head-butt, and then finish them off with a fast-firing missile shot straight from his mouth!
