When Motormaster (aka Motorbreath) booms out orders in his hollow, bottomless-deep voice of doom, his Stunticon soldiers listen in very real fear. (Hey, if your boss could barrel at top speed through a concrete block 20 feet thick and turn it to rubble like it was no big deal, you'd be terrified of disobeying too.) A cold and brutal tyrant, without an ounce of mercy or care for any lesser being, he considers himself the true "King of the Road." He longs to one day prove his claim by destroying Optimus Prime, though he knows that Megatron might kill Prime first.
