When Motormaster booms out orders in his hollow, bottomless-deep voice of doom, his Stunticon soldiers listen in very real fear. 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 in a head-on collision, though he fears that someone else might kill Prime before he can. His fellow Stunticons hate him, but are too terrified of him to dare disobey his orders.
