Roll out with Optimus Prime, Bumblebee, Arcee, Ratchet, Bulkhead, and more as the heroic Autobots battle the evil Decepticons. Now that big bad Megatron has a rare element that lets him rule over life itself, "Team Prime" needs human help more than ever. That's where the Teens -- Jack, Miko, and Raf -- come in. As they work together to defend Earth, the drama is just as intense as the heavy metal action.
Unicron returns and takes over Megatron's body to have revenge on the Autobots and ultimately destroy Cybertron. The Autobots, Decepticons, Predaking and two new Predacons must team up to protect their plant and destroy their accursed enemy once and for all.
