Regeneration.At the A-Base, Red Alert informs the rest of the team that he may be able to rebuild Smookescreen, since his spark (heart) still has a pulse. But that there is also chance that he may die while Red Alert is working on him. Meanwhile, Starscream, dirty, battered, bruised, and outraged finally returns to the D-Base and creams Thrust for closing the Warp-gate on him after which Megatron indifferently tells him to go clean himself up. Whilst Starscream's in the energon-bath-chamber, Demolishor shows up and demands that the Mini-cons be handed over on Megatron's orders. Starscream intimidates Demolishor and goes to Megatron personally. However, Megatron and Thrust plan to use Starscream as their personal dummy as a distraction to hopefully defeat the Autobots, but Starcream overhears their plot to rid of him. Starscream, fed up with being Megatron's punching bag, finally snaps and takes a swing at him with the Star Saber that turns the Decepticons against him. His rebellion leads him to injure most of the Decepticon soldiers and runs away, taking the Star Saber with him. Back at the A-Base, Hot Shot and Sideswipe are training when they hear the signal of the Decepticon's presence. Hot Shot, wanting revenge for Smokescreen, decides to go out and fight the Decepticons along with Sideswipe, but much to their surprise, it is Starscream being chased by Tidal Wave. Starscream is shot down and the two Autobots decide to fight. How Shot takes on Tidal Wave while Sideswipe chases Starscream. Optimus and Jetfire arrive to help and the two link up into Jet Convoy, but are no match for Tidal Wave's impenetrable armor. Starscream wishes to help and tosses Optimus the Star Saber and is able to damage Tidal Wave, forcing him to retreat. Starscream surrenders to the Autobots and asks them to join them. The Autobots are skeptical, however, believing that he will betray them at a certain point, but the kids believe that they can trust Starscream, which convinces Optimus to let Starscream join the Autobots. In turn, Starscream offers his data of the D-Base so that the Autobots can invade the Decepticons and rescue the Mini-Cons. Late that day, Hot Shot, who still doesn't trust Starscream, challenges him to a fight. The rest of the Autobots notice that both of them are missing when they are interrupted by Red Alert, who says that Smokescreen's spark was saved, but his body wasn't. Meanwhile, Hot Shot and Starscream are still fighting when a different Transformer breaks up the fight. The Transformer turns out to be Smokescreen with a new body, who tells Hot Shot that he appreciates Hot Shots actions to avenge him, but that he needs to get along with Starscream to defeat the Decepticons. Now, the Autobots are back in possession of the Star Saber and now have a new team member on their side.
