Starscream, still in command of the Decepticons after Megatron’s disappearance in the Space Bridge, leads Thundercracker and Soundwave in attacking a hydroelectric power generator. The Autobots respond quickly, as Optimus Prime arrives with an assault team. The battle is short, as a thrown piece of equipment destroys the Decepticon store of Energon Cubes. With little to show for their efforts, the Decepticons retreat. Optimus Prime sends Prowl and Bluestreak to follow them.
