The Cybertron Headmasters learn for the first time from Hawk of the Cybertron's most important operation, the Godbomber Project. The Transformer, known as Godbomber, is being constructed, according to Grand Maximus' specifications, to combine with Super Ginrai to create the ultimate Godmaster, God Ginrai. Devil Z hears of this plan and decrees that Super Ginrai must be destroyed before the project can be completed. Unfortunately, Ginrai has been convinced to be a stunt driver in a clever Destron plan. He drives his truck around a series of mines but gets blown up by an uncharted mine. He faces off with Buster and Hydra, managing to defeat them but then meets the Godmasters Giga and Mega, whose transtectors occupy a single merged form, Overlord. Overlord then proceeds to completely beat up Super Ginrai, leaving him for dead, but somehow he manages to survive the brutal assault.
