Five years later, after the defeat of Unicron, the Decepticons were engaged in an extended guerrilla war with the Autobots for control of Cybertron. Later, Motormaster sieged the lab of Swofford and Morgan with Galvatron, and became one of the first Decepticons infected with the Hate Plague. After Starscream had disposed of Megatron by making him fall into Cybertron's vast underground, he had Motormaster forcibly extract the data held within Laserbeak to uncover what Megatron had been planning prior to his take-over. Though Superion was crippled by the Omega Wave Cannon, the Stunticons, as well as the rest of the Decepticons, were sent packing when a massive amount of Autobot reinforcements arrived to turn the tide of the battle.

Motormaster and the rest of the Stunticons were created in response to the failure of a Decepticon campaign to acquire Autobot superfuel.This unchanged release of Legends Class Motorbreath comes packed with Generations Legends Class Thundercracker, as well as Deluxe Class Combat Hero Optimus Prime and a Generation 2-styled Deluxe Class Autobot Jazz. These sections form both arm frames, both leg frames, the torso frame, a gun, and a pedestal for that gun. During the Dark Ages, he joined up with Starscream's Predacons, helping him steal raw energon, only to have Grimlock and the Lightning Strike Coalition steal the energon. Despite possessing translucent plastic and more lopsided stats than a regular Bot Shot, he is apparently not labeled as a Super Bot.

After getting a tip from the Quintessons, Soundwave had Motormaster and his other lieutenants gather the troops for a full-scale attack on the Autobots. Motormaster was later present with Megatron's troops outside their base when Soundwave and Starscream announced they were taking over. Generations Legends Class "Motorbreath" (named so for trademark reasons) is a redeco/ retool of Reveal the Shield Legends Class Optimus Prime. Though Megatron's paranoia had grown to extreme levels by this point, Soundwave persuaded him that Motormaster's "idea" of using weight of numbers against Prime had some merit and Megatron sent for the Predacons. Once they did, the Stunticons drew attention to themselves by demolishing a highway, and then pretended to be "defending" Skids once RAAT forces arrived.
