The Headmasters cartoon
On their journey back to Earth for their final plan, the Decepticons in Scorponok's transtector stopped at Pallas so the propulsion system of the giant ship could be repaired. There, Sixshot, who had been abandoned on Daira, rejoined the Decepticons, not knowing of Scorponok's careless disposal of his life.

The Decepticons soon preemptively attacked the following Autobots in Battleship Maximus and the battle was taken to Pallas. The violence was stopped when Sixshot challenged Chromedome to a duel on Juno. After planting bombs on Juno to kill Sixshot, Scorponok and the other Decepticons left Pallas for Earth.
