Cab's childhood-friend Copo is struck by a circulatory disease, but the decepticons are kidnapping doctors all over the world: it is revealed by Mega that they intend to diminish humanity's will to live. Luckily at least one doctor, Dado, got away and directs the godmaster-autobots where to free the rest. While Road-King, Ranger and Lightfoot keep the Destrons busy, Ginrai sneaks pass to free the doctors, but couldn't exactly save all of them at once: despite this Copo's personal doctor named Rhodan was persuaded to go first so that he could cure Copo, and does, but the seacons refuse to let them leave without a fight. The godmasters unleash their best super-moves and triumph, then hurry to Viscas Island with Rhodan, who finally cures Copo.
