About The Transformers
Unicron, a roaming artificial planet, devours robot planet Lithone. Though many inhabitants attempt to flee the planet in spaceships, only one escapes.
The evil Decepticons have gained control of the Transformers' homeworld, Cybertron at some point in the twenty years since the beginning of the struggle between the robotic warriors on Earth. The heroic Autobots are using two of Cybertron's moons as staging areas, preparing to strike against the Decepticons. A supply shuttle is readied for launch to Autobot City on Earth. A transmission is intercepted by the Decepticons, who ambush the shuttle and kill its crew, intending to use the ship to infiltrate Autobot City.
On Earth, Daniel Witwicky and Hot Rod fish in a lake near Autobot City, discussing Daniel's loneliness, as his father Spike is on one of the moon bases. They pick up the shuttle's signature, and race up to Lookout Mountain to see it land. They spot the Decepticons and launch a preemptive strike. After a brief battle, the Decepticons attack Autobot City. The Autobots, including Ultra Magnus, Blurr, Springer, Perceptor and Arcee, transform Autobot City into a fortress. As a siege ensues, Ultra Magnus orders Blaster to radio for assistance from Optimus Prime. The next morning Optimus and the Dinobots repel the Decepticons.
Optimus confronts his arch-enemy, Megatron. Though Megatron is defeated, Optimus is critically wounded due to Hot Rod's interference. Starscream takes command of the Decepticons and retreats with their fallen leader and other wounded aboard Astrotrain.
Perceptor informs the other Autobots that Optimus Prime's wounds are fatal. Optimus calls on Ultra Magnus to assume command of the Autobots and gives him the Autobot Matrix of Leadership. Before dying, Optimus asserts that the Matrix will one day light the Autobots' darkest hour.
