Profile: On the road, there is not a 16-ton hunk of rolling steel more cold and cruel than Motormaster. He shows mercy to none, least of all the unfortunate human drivers who happen to be sharing a highway with him. He'll brutally barrel through any traffic tie-up- he'd even roll over a baby carriage if it were in his way. He doesn't care- he knows nothing on wheels can survive a collision with him, except, perhaps, Autobot Leader Optimus Prime- and Motormaster would give you an argument on that. In fact, he looks forward to that very confrontaion so he can destroy Optimus and claim, without reservation, he is 'King of the Road." His Stunticon followers tremble before his commands, which he gives with a thundering voice that has the hollow, doom-laden tone of an echo from a bottomless well. They hate him, but they fear him too much to disobey him.
Abilities: In truck mode, Motormaster is virtually unstoppable. At his top speed of 140 mph, he can ram a 20 foot-thick block of concrete and crumble it without cracking a headlight. In robot mode, he has enormous strength and carries an atom-smasher cannon, which shoots a high-energy beam of protons that can shred all but the densest materials. He combines with his fellow Stunticons to form the giant robot Menasor.
Weaknesses: Other than being highly fuel-consumptive, Motormaster has no known weaknesses.
