Essentially a movie involving the battle between the heroic Autobots and the evil Decepticons, two warring factions of transforming robots from the planet Cybertron, the plot also involves the giant planet named Unicron, who's ready to consume anything that stands in its way. The only thing that can stop Unicron is the Autobot Matrix of Leadership, which is possessed by the Autobots and which the Decepticons, through Unicron's orders, plan to take away from them.

This movie features an all-star voice cast consisting of Leonard Nimoy ("Star Trek") as the voice of Galvatron, Judd Nelson as Hot Rod, Robert Stack ("Unsolved Mysteries") as Ultra Magnus, and in his final role two months prior to his death, Orson Welles ("Citizen Kane") provides the voice of Unicron. This movie is also known for its soundtrack featuring Stan Bush's "The Touch" and Weird Al Yankovic's "Dare to be Stupid".
