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! 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 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!
