Calvin Wimmer voices Demolishor, who transforms into a white Terex O&K RH 400 hydraulic mining excavator. In robot mode, his treads turn into huge wheels, enabling him to roll either on the two of them, or only on the front one, with the rear one lifted behind his head. During production, the film writers simply called him "Wheelbot", and he is erroneously listed by that name in the film's credits. Also, he is referred to as "Demolisher" in the film novel. and heres the link Transformers: Revenge of the Fallen - Wikipedia, the free encyclopedia don't know if this is real or not. sorry if this is old.
