Godzilla vs. Destoroyah

In an alternate timeline the original Godzilla is never defeated and repeatedly reemerges to feed on Japan's energy sources. A new inter-dimensional weapon called the Dimension Tide is created with the intent of eliminating Godzilla. However, the new weapon might also serve as a gateway to something far more sinister.

War reduced Japan to zero, and Godzilla plunged it into minus. Two years have passed since then, and the country has faced agonizing struggles to achieve recovery and finally reclaim its daily life. Just as humanity managed to cling to a hard-won peace, a new threat strikes, crushing hope in an instant. There is no third time. Everything ends here.

After the previous Godzilla attack, a miniature arms race ensues to collect his cells. Concerned over Godzilla's possible return, the Japanese government uses the cells to create a new bio-weapon, ANEB (Anti-Nuclear Energy Bacteria). They seeks the aid of geneticist Genshiro Shiragami, who's experiments result in a new mutation.

Godzilla has become a distant memory for Japan when the destruction of a US submarine raises alarms for Admiral Tachibana. His estranged daughter Yuri investigates the legend of the guardian monsters, who must rise to protect Japan against the vengeful spirits within Godzilla that seek to destroy both the nation and its people for the suffering they inflicted in the Pacific conflict.

Astronauts Glenn and Fuji investigate Planet X and encounter mysterious aliens known as the Xiliens, who ask Earth's people to help save their world from "Monster Zero". In exchange for borrowing Godzilla and Rodan, the Xiliens offer a cure for cancer. As Glenn investigates, he develops a romance with Miss Namikawa and uncovers the Xilien's true intentions.
