There was a time when BRIMSTONE was king of the roads on CYBERTRON. He was meaner, faster and tougher than anything else on wheels, and he made sure everyone knew it. The only rival he ever really had was HUBCAP. So it was only natural they ended up on opposite sides in the war. BRIMSTONE may be older now, but he's also meaner, and there's no way he's going down without taking HUBCAP with him.
