The leadership is passed back from Rodimus Prime to Optimus Prime and both Cybertron and Earth are at peace. Suddenly in the year 2011, the space bridge reactivates and Galvatron, along with his new set of Decepticon warriors, Skullcruncher, Mindwipe and Weirdwolf, launch a new campaign of terror. The Dinobots and the Technobots head out to stop the Decpticons, while on Earth, Optimus Prime receives word of the Decepticon attack. Sixshot leads his brigade against the Autobots and Ultra Magnus. Meanwhile, Daniel and Wheelie run into Trypticon, but manage to trick him into crossing a flimsy bridge and falling down into the river below. As Sixshot and Ultra Magnus duel, the Railbots suddenly arrive and the Autobots head back toward base.
