Optimus Prime and the Autobots are faced with a new kind of war. Alliances that once were strong now stand in doubt. Nonetheless, Earth needs their protection more than ever. Optimus Prime adapts, redesigning his alternate mode so he can move unrecognized. If he cannot fight the battle with firepower on the front lines, he can fight it with covert maneuvers from the edge. Grimlock is the ultimate wild card. The Dinobot leader has the power to decide the fate of Earth almost singlehandedly. His ferocious strength makes him a devastating force in battle. If that strength can be focused and harnessed for good, it could be enough to turn the tide. If not, it might be what seals Earth's doom.
