Plot
On Cybertron, a war rages between the good Autobots and the evil Decepticons for the power of the Mini-Cons, which are smaller power-enhancing Transformers. The Autobots try to help the Mici-Cons escape the war torn planet, but their ship is attacked by the Decepticons as they enter a space bridge. This causes an explosion which scatters the Mini-Cons across the globe.

Investigating the crash site, Daniel Witwicky and his crush Carly Spencer discover the Mini-Con ship and accidental activity a beacon, alerting the Cybertronians to the presence of the Mini-Cons on Earth. Earth is soon invaded by forces from both sides, with the Autobots led by Optimus Prime and the Decepticons by Megatron. When the Autobots save Daniel and Carly, they become their protectors and friends.

The Transformers learn of the prophecy that the planet destroyed Unicron will return. Megatron, believing that if he can control Unicron he will be unstoppable, decides to try and use the Mini-Cons to reawaken him. He sends his second-in-command, Starscream, as well as Blackout, another Decepticon, to find one which has been located in a desert near to the city. Daniel and Carly become caught up in the crossfire, but Starscream attacks Blackout and defeats him before he can kill the humans. Scorponok then steals the Mini-Con and brings it to Megatron. That night, Megatron is confronted by Starscream in the desert as both sides watch, with Starscream desperately pleading with Megatron not to free Unicron. Megatron laughs him off and powers up the Mini-Cons. Suddenly, the Earth's moon sheds it's skin and transforms into Unicron, revealing that he had been imprisoned there all along. Starscream battles Megatron but is killed. Optimus attacks Megatron and the Decepticon retrieves the Autobot Matrix, the last thing needed to fully empower Unicron. Suddenly, the Decepticon Sideways appears and steals it, revealing himself at the true herald of Unicron. Optimus then convinces Megatron to have the Autobots and Decepticons work together in order to defeat Unicron before he can destroy Earth.

During a fierce battle, Optimus and Megatron are swallowed by Unicron and find their way to his core, where they are confronted by Sideways. Sideways captures them and taunts them, telling Optimus that he is the same as Megatron in his war efforts. Overcome with rage, Optimus is able to awaken the sleeping Mini-Cons, which disable Unicron. Optimus then destroys Sideways.

With Unicron shut down, Megatron challenges Optimus to a final battle, explaining that they must now decide the fate of the Transformers. However, the negative energy which comes about as a result of the battle reawakens Unicron. The fight culminates in Optimus and Megatron dangling over Unicron's maw. Megatron tells Optimus that without the cycle of hate they form, Unicron will be powerless. He then cuts himself free of Optimus' hold and falls to his death, sacrificng himself to finish Unicron, who vanishes in a brilliant flash of light. As Optimus floats through space, the Matrix floats towards him and he reflects on Sideways' word and feel dishonoured, deciding he is unworthy of the Matrix and chooses to go into exile.
