Autobots, Decepticons, Predaking and Predacons form an unlikely alliance to battle a resurrected Unicron.

When new Decepticons appear, Optimus Prime summons Bumblebee and gives him the task of saving Earth. To help him, the veteran Autobot assembles a rogue team of young bots to capture the new enemies. The new Autobot recruits include a rebel “bad boy,” an elite guard cadet, a bombastic dinobot and a hyperactive mini-con. The recruits provide a challenge for Bumblebee because, while each is a fully capable hero, they are inexperienced when it comes to working as a team. So Bumblebee has to learn how to balance his role as a leader of the new squad with his job of fighting evil forces as he works to complete the mission.

Roll out with Optimus Prime, Bumblebee, Arcee, Ratchet, Bulkhead, and the rest of the heroic Autobots as they battle the evil Decepticons. Now that big bad Megatron has returned with a mysterious and dangerous element, Team Prime must prepare for an epic battle.
