Runamuck
"The road is my playpen, cars are my toys."

For most of his life, Runamuck served as a spy and courier for Megatron, carrying messages to Decepticon warriors behind enemy lines. Since his leader's disappearance, though, Runamuck has been pretty bored. Too many Autobots around meant he couldn't get away with much. But now, with the Autobots forced into hiding on Earth, he's having the time of his life tormenting them by striking at vulenerable targets in front of a lot of human witnesses, where the Autobots can't counterattack.
