I bring you the extended bio for Roadbuster, ground assault commander and prominent member of Kup's crew in All Hail Megatron:
Code Name: Roadbuster
Function: Ground Assault Commander
Profile: "Demolishing Decepticons / is the way Roadbuster prefers to pass the time. If he's not fighting, he's just not happy. This isn't because he's particularly hot-tempered -- he just bores easily. When not in battle he's usually the most quiet of all the Autobots. But give him an enemy and he reverts to rough no-nonsense form and attacks with a zest unsurpassed by any of his comrades. It is in combat situations that his charisma surfaces, inspiring his fellow warriors and making him a natural leader. "With Roadbuster leading us, no one worries about consequences," says Tracks. "We just want to scrap some steel!"
Abilities: In jeep mode, Roadbuster can cross all but the most extreme terrains. He can traverse swamps, rocky hillsides, ice and mud without any problems. He has a range of 600 miles. He carries a turret-mounted linear blaster gun which can blow a hole through two feet of concrete. In robot mode he has a laser rifle as well as a shoulder-mounted shrapnel-missile launcher.
Weaknesses: As a result of his tendency to tune out non-combat situations, Roadbuster is sometimes unaware of impending danger. It is only when he is directly confronted by it that he will react, and by then he is often in more trouble than he can handle.
