In the Pyramid Desert Battle scene from : Revenge of the Fallen, Constructicon Mixmaster and his Constructicon comrades rumble in from all directions and surround Leo Spitz, Seymour Simmons, Skids, and Mudflap. The humans look up in terror as the desert sand begins to quake and the Constructicons combine to form the brutal Devastator. During the merge, Constructicon Mixmaster latches on as the combiner's head. Once fully formed, Devastator unleashes mayhem and destruction across the desert.
