Later, the Transformers were all transported to Cybertron by Primus to battle Unicron. Although Unicron had tainted the Matrix after killing Thunderwing, Prime managed to reacquire and purify the Matrix. Prime then sacrificed his life one more time to destroy Unicron by plunging the Matrix into his maw. The Powermaster process, however, had been working to fully bond Prime and Hi-Q. Prime's death completed the process, and the two minds and souls became one. Hi-Q's biomechanical body was stripped down and reconstructed by the Last Autobot, resurrecting Optimus Prime once more with the two minds now one. Prime rejoined the other Transformers on the planet Klo and routed Bludgeon's Decepticons.
