The Mystery of Planet Master

The four robots who mysteriously appear do battle with the Destrons, who happen to be Headmasters as well. Wipe tries to put Brainstorm to sleep, but a blast from Chromedome saves him. Convoy is in serious jeopardy from Galvatron until Hot Rodimus appears and saves him. A fierce battle rages between the Cybertron and Destron gestalts, until the mysterious spaceship shows up and sends the Destrons running. Fortress appears from inside the base and Cha recognizes him as an old friend. Fortress then explains to the Cybertrons the origins of the Headmasters -- how they had created the bodies for themselves on the planet Master. Meanwhile, Convoy heads toward Vector Sigma when he suddenly is aided by the appearance of the ghost of Alpha Trion. Blaster gives Wheelie a tape of his for some unknown reason as he heads back to Earth with Hot Rodimus and Ultra Magnus. As they enter the base, Blaster spots Ratbat and sends Steeljaw after him. It turns into a tape free-for-all as Soundwave appears.
