Slapdash eventually returned to Nebulos with Goldbug, Joyride and Getaway, hoping that Nebulan science could build a new body to house the mind of Optimus Prime. When the Autobots refused to leave the planet even after being warned about the poisoned fuel, Hi-Q agreed to construct Prime's new body, while the Autobots drained their energy fending off an attack by the Decepticon Powermasters. Prime's mind was placed within his new body, but he immediately began to die due to the Nebulan fuel that powered it. Realizing the nobility and humanity of the Autobots, Hi-Q agreed to save Prime's life by merging with him as a Powermaster, while his assistants, Rev, Hotwire and Lube bonded to Getaway, Joyride and Slapdash to save them. Dreadwind and Darkwing were defeated by the new Powermasters and exiled from Nebulos, while the Autobots left to rejoin their fellows on Earth.
