Here, the Mayhems found the Autobots being told the story of Cybertron's origins by the Keeper.
Despite being on holy ground, Bludgeon and his compatriots attacked, with Bludgeon gaining the upper hand against Jazz until Bumblebee managed to sneak up on him.
He was there also to quell the sudden Unicron cultist uprising, remarking that to a master of Metallikato, their moves were like slow motion.
Thankfully, Optimus Prime's sacrifice saved them all, and Bludgeon was there standing over Prime's body with a few others as he died.
Bludgeon is a ferocious warrior, skilled in the ancient Cybertronian martial art of Metallikato.
He and his blade can cut through the battlefield as if everyone else is operating at a minimal speed setting.
While Bludgeon openly kept the peace (like keeping Fangry in line at meetings), he and Krok began to worry that some of the Decepticons were in favour of peaceful alliance and plotted to break it up.
Utterly vicious and aloof, Bludgeon is also highly religious, adhering to an arcane code of honor.Bludgeon was lured into a nearby canal, where Seawatch grappled him and hoisted him away with his boat mode.In his absence, the battle inadvertently awakened the slumbering Primus.Carnivac swore that Bludgeon and the other Mayhems would pay for killing his friend.He later took on the leadership of Thunderwing's new Mayhem Attack Squad, sent to slay the newly resurrected Jazz, Bumblebee, and Grimlock.
