The Godbomber-project is nearly complete, but at the Weather Observatory Moon Base, Mega and Giga have taken over and Blackzarak is getting closer. Ginrai still sulks over his defeat at Overlord's hands two episodes ago until the Project was finally finished. Upon testing it out he becomes "God Ginrai" and sets course for the moon to rescue the moon-base's staff who are being held hostage, but Mega and Giga, having been alerted to his approach by Devil Z, set off to stop him, but this time, it was Ginrai who was the better fighter and forces Overlord to fallback with Ginrai on his heels, but BlackZarak finally arrives for the ultimate battle.
