As the AUTOBOTS race to hide the AllSpark, the DECEPTICONS close in. BONECRUSHER catches up to the AUTOBOT convoy on the freeway near Mission City, ruthlessly tearing through civilian traffic in an effort to reach the AllSpark before the AUTOBOTS can stop him. Sick of the carnage, OPTIMUS PRIME takes it on himself to stop the hulking DECEPTICON once and for all. He falls back, converts to robot mode, and dives into battle with his energy sword ready.
