Description: Ten years after the epic Unicron battles, the Autobots and leaderless Decepticons have formed an uneasy alliance. When Energon - the rare and potent substance over which the Transformers have fought for eons - is discovered on Earth, mysterious forces return to control the Energon at any cost. Only an elite team of Autobots, the heroic "robots in disguise," can save the planet from total destruction.
Includes "Cybertron City", "Energon Stars", "Scorponok", and "Megatron's Sword".
