Transformers: The Headmasters

The Mystery of Planet Master (1x2)

:

The four robots who mysteriously appear do battle with the Decepticons, who happen to be Headmasters as well. Mindswipe tries to put Brainstorm to sleep, but a blast from Chromedome saves him. Optimus Prime is in serious jeopardy from Galvatron until Hot Rod appears and saves him. A fierce battle rages between the Autobot and Decepticon gestalts, until the mysterious spaceship shows up and sends the Decepticons running. Cerebros appears from inside the base and Kup recognizes him as an old friend. Cerebros then explains to the Autobots the origins of the Headmasters -- how they had created the bodies for themselves on the planet Master. Meanwhile, Optimus Prime 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 Rod and Ultra Magnus.
