The Transformers: The Movie

THE TRANSFORMERS: THE MOVIE is set in the "future" year 2005. The good Autobots are in an ongoing war against evil Decepticons. When their planet fell to the Decepticons, the Autobots befriended humans and set up a base on Earth. Now the Decepticon warlord Megatron (voiced by Frank Welker) is launching a sneak attack on Earth's Autobot city, determined to get rid of Autobot leader Optimus Prime (Peter Cullen) once and for all. The battle shakes up everything on both sides but makes the Autobots even more determined to protect a luminous orb called the Matrix, which has the power to "light the darkest hour." Meanwhile, a new menace comes on the scene, a robot called Unicron (Orson Welles)—a planet-sized machine that destroys and eats other planets. The only thing posing a threat to Unicron is the Matrix, so the monstrous robot makes a deal with a battle-damaged Megatron to transform him into the powerful Galvatron (Leonard Nimoy) in order to capture it.
