Megatron infuses The Nemesis w/ his own supply of Dark Energon which results in the ship taking on a life of its own with its own agenda. Meanwhile Optimus reluctantly decides to use the Spark Extractor in an attempt to bring the war to an end.
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.
But that's not so easy when they have to guard over Jack, Miko, and Raf, three normal kids who've accidentally discovered the Autobots. As Team Prime works to defend Earth from destruction, the drama gets just as intense as the heavy metal action.
