In Okinawa, a prophetess predicts that monsters will soon overrun the world. The first signs of the coming destruction are found by Masahiko Shimizu and his brother Keisuke. When they explore a newly discovered cave, they find samples of a strange, unearthly metal and a statue of a lionlike creature.
Keisuke meets Saeko, an archaeologist who can translate the inscription on the statue. “When a black mountain appears above the clouds, a monster will come and try to destroy the world,” the hieroglyphics read.
Saeko and Keisuke board a plane to deliver the statue to Professor Wagura, and while in the air, they see the eerie vision of a black mountain over the clouds. Meanwhile, brother Masahiko learns that the metal he discovered is called space titanium.
Suddenly an earthquake strikes and Godzilla arrives to destroy Japan.
Anguirus, Godzilla’s old friend, soon arrives, too, but Godzilla attacks it instead of greeting. During the battle, Anguirus tears off a piece of Godzilla’s hide to reveal a patch of space titanium. Soon this Godzilla is confronted by another Godzilla!
During the battle of the twin titans, the false Godzilla is revealed to be arobot called Mechagodzilla.
The prophetess reveals that Earth has one hope―King Ceaser. But the monster cannot be revived without the lionlike statue. Unfortunately, a weird alien race of intelligent apes, the Simeons, is out to steal the statue.
Finally, with the help of an intrepid Interpol agent, the prophetess is presented with the statue. With a ritual song, she awakens King Ceaser, who confronts Mechagodzilla. Soon Godzilla arrives and rips Mechagodzilla’s robotic head off. Together, Godzilla and King Ceaser have saved the world.
