Godzilla Legend: The Asuka Fortress

Godzilla Legend: The Asuka Fortress (ゴジラ伝説 アスカの要塞 Gojira Densetsu Asuka no Yōsai) is an unmade 1979 Godzilla film. In the year 2000, Godzilla has been successfully sedated deep within the Japan Trench by means of a special frequency. Meanwhile, the scientist Dr. Yasuto Ito has invented and constructed a new superweapon dubbed the Asuka Fortress (or Big Boy in later drafts); a mountainous robotic supercomputer built to defend Japan against all threats. The Prime Minister of Japan intends to use the giant robot to enforce 'world peace' under the banner of the World Peace Unicom League, but instead both he and his cabinet end up becoming the Asuka Fortress' first victims when it gains independence with the goal of exterminating all other life on Earth. Realizing how desperate the situation has become, a group of computer technicians and scientists who helped build the Fortress, led by a man named Son of Heaven, free Godzilla from his underwater prison to battle the rogue superweapon. The Asuka Fortress recognizes Godzilla as the only being capable of destroying it and constructs and sends forth several robotic minions to assassinate the King of the Monsters. Godzilla eventually makes his way to the Asuka Fortress itself but the machine proves too powerful for him to defeat until Son of Heaven and his friends infiltrate the Fortress and shut it down from the inside. With the Asuka Fortress deactivated and the human heroes out of harm's way, Godzilla obliterates the motionless mechanical behemoth.[1][2]
