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 shred all but the densest materials. Combines w/ his fellow Stunticons to form the giant robot Menasor. 

Weaknesses: Other than being highly fuel-consumptive, he has no known weaknesses.
Other Appearances:  Motormaster has not appeared in the TF Universe besides those of the G1 era.

Although none of the Stuntacons have made appearances through the rest of the TF Universe, a key factor in their creation involves an item Beast Machines fans will certainly recognize, the Key to Vector Sigma!  

Megatron stole the key on Cybertron from Optimus Prime's creator Alpha Trion in order to activate "Vector Sigma" (shown below to the right) & give life to the Stuntacons.  According to the explanation from Megatron, "Vector Sigma is the super computer that gave us all (Transformers) life."  When activated with the key, Vector Sigma came to life and said to Megatron, "I am Vector Sigma!  Before Cybertron was, I WAS!  Who awakens me?"  This genie-in-a-bottle type of entity has the power to bestow personalities into robots; basically Vector Sigma can create a "Spark."

Later in the two part classic G1 episodes "Key to Vector Sigma," Megatron discovers that on earth the Key has the power to turn organic matter into technological, just like in Beast Machines!
