Dr. Hell, Mazinger Z's main enemy, has been defeated and killed in battle, and finally Kouji Kabuto and the rest of his friends can take a break from their duty of defending Japan and the world from evil. However, during a storm after a very hot day in the beach, Boss, Mucha and Nuke have a disturbing vision of a prophet that heralds the end of the world, claiming that the dead will raise and destroy the human race, and that the General of Darkness will attack from air, sea and land. The only hope of defense is an iron fortress, Mazinger. After these words, the strange figure disappears. When Boss tells these events to Koji and Sayaka, they barely credit what he says, mocking him and disregarding this prophecy as only an illusion caused by the intense heat. They start listening to music on the radio, but are soon interrupted by reports of attacks by bizarre monsters in several important cities including London (attacked by Aquatic Beast Arimoth), Moscow (by Reptile Beast Gurosten), Paris (by Superhuman Beast Arsoth), and New York (by Aerial Beast Orbee).
