Having escaped from his chains, Optimus Prime attacks Serpent O.R. Prime has a strong advantage, being much larger than Serpent O.R., but several Decepticons, including Motormaster and Razorclaw, rush to the aid of their leader. While Prime individually fights off his attackers, a recovering Serpent O.R. notices a wound in the back of his neck. Outmatched by his opponents' combined might, Prime signals Hot Rod to attack. Now joined by the forces of G.I. Joe, the Autobots storm the Decepticon base.
