Megatron has died in a huge explosion that has destroyed the Decepticon’s Space Bridge. After Starscream assumes command, Megatron is found in the wreckage, where he had remained in stasis. The Autobots battle a number of different villians, including M.E.C.H. as the Decepticons regain power. Knock Out, Skyquake, Makeshift and Breakdown join their side, tilting the balance of the war. This leads up to Unicron the Chaos Bringer threatening the earth. The Autobots must work with Megatron in order to save the world from Unicron. During the intense battles, Optimus Prime loses his memory and becomes Orion Pax, giving the Decepticons further advantages in the war.
