This theatrical movie based on the television series (which was also based on a popular multiform robot toyline) did not impress very well at the box office. The movie takes place in 2005, twenty years after the television series, and chronicles the efforts of the heroic Autobots to defend their homeworld Cybertron from the evil Decepticons. Despite the invasion, the Autobots are determined to retake their homeworld and head for Autobot City on Earth for supplies. The Decepticons hijack and commandeer their ship, resulting in a fierce battle before a hideous menace heads their way. That hideous menace is the colossal demon known as Unicron, who has been ready to consume any massive planet 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.
