Summary:
The Autobots and their human comrades have been separated, following the destruction of their headquarters, and Optimus Prime is badly injured. Unfortunately, it is just the beginning of their troubles, as the powerful Decepticon Shockwave has come to Earth with his newest weapon: a clone of one of Cybertron's most ancient and fearsome beasts, Predaking. Now it's up the Autobots and their allies, both old and new, to reunite and protect the world from evil one last time.
