In his first form, Cerebulon was actually within the giant UFO which was hovering over Tsunopolis which then brought you to the mothership in Earth's orbit, and finally crash lands back on Earth after your battle with the three Zorgulon destroyed the mothership. He emerges from the ruined craft, smashing through the largest monument on the concourse in a smaller saucer mech-suit of sorts that is mobilized by four legs and two protruding arms that will shoot a death-ray when the hands are joined. The "head" of this suit is protected by a force-field.
