Long before the dawn of man on Earth, the war between Autobots and Decepticons raged. Two titans - huge metal warriors, each committed to total victory - emerged as leaders. Optimus Prime, wise, just and gentle despite having strength enough to move mountains took command of the Autobot forces, hoping to lead his people to peace and freedom. Megatron, an evil, destructive tyrant bent on total domination of the universe and all its resources led his Decepticons on an endless war of conquest. For millions of years their battle has raged like fire across the galaxy, and now they are here on Earth in a fight to the finish that will determine the fate of the planet and all its people.
