The Transformers: The Movie is a 1986 animated science-fiction film based on the popular Transformers franchise. The film is set in the year 2005, and the Autobots and Decepticons are still battling for control of the universe.
The story begins with the Autobots defending their home planet of Cybertron from a massive attack led by the Decepticons. During the battle, the Autobot leader, Optimus Prime, is mortally wounded and passes on the Autobot Matrix of Leadership to his protege, Ultra Magnus.
Meanwhile, a colossal robot called Unicron, who travels the universe devouring planets, sets his sights on Cybertron and the Autobots. Unicron learns of the Matrix and seeks to obtain it, as it will grant him incredible power.
The Autobots, along with their human ally, Spike Witwicky, must stop Unicron before he destroys their planet and uses the Matrix to become unstoppable. Along the way, they encounter new Transformers, such as the daredevil Autobot Hot Rod and the spunky Dinobot Grimlock.
The film is notable for its dark tone and the killing off of many beloved characters, including Optimus Prime, which caused controversy among fans.

Ultra Magnus is unable to handle the power of the Matrix and is gravely injured, but Hot Rod steps up to become the new Autobot leader, now armed with the power of the Matrix. The film ends with the Autobots returning to Cybertron, having won a hard-fought victory against the Decepticons and Unicron.
