A thick fog covers the seashore. Suddenly, as if out of a primeval dream of terror, a massive reptilian form obscures the window of a lonely lighthouse. It has razor-sharp teeth in a gargantuan mouth; claws that can cut through steel; a roar that echoes back through the centuries; dorsal fins that resemble crimson lightning bolts; and fiery breath that incinerates everything it touches. Soon, all in the creature's wake is utterly destroyed, and a terrified Japan can only wonder where this monstrous beast will next appear. Godzilla, king of the monsters, is back. This time it faces a formidable new foe in Orga (aka Giant Alien Millennian), a gigantic, lethal creature that has slowly transmuted from a UFO believed to be dormant for 6,000 years.
