Motormaster

Motormaster is the name of several fictional characters from the Transformers universe. Motormaster made his first appearance in the Marvel Transformers comic before appearing in the animated series. Other than in Transformers: War for Cybertron, Motormaster is the leader of the Stunticons, an all-car group created by Megatron to counter the dominance of the Autobots on the road. Due to difficulties Hasbro had in trademarking the name Motormaster since his original incarnation, toys originally intend to be Motormaster have been released as Menasor instead, despite looking like Motormaster.
