And in this sequel it appears some of the machines are even bigger...
The battle for Earth has ended but the battle for the universe has just begun. After returning to Cybertron, Starscream assumes command of the Decepticons, and has decided to return to Earth with force. The Autobots, believing that peace is possible, finds out that Megatron's dead body has been stolen from the US Military by Skorpinox who has revived their leader using his own spark. Now Megatron is back seeking revenge and with Starscream and more Decepticon reinforcements on the way, the Autobots, despite finding reinforcements of their own, may have more to deal with than meets the eye.
