Evil Space Aliens called the Xilians unleashes all the Earth’s monsters to lay waste to most of the world’s major cities, including Tokyo, New York, Sydney, Shanghai and Paris. It is up to Godzilla and the Earth Defense Force to vanquish the monsters and aliens to rescue the world in the ultimate “Save the Earth” battle.

Japan is thrown into a panic after several ships explode and are sunk near Odo Island. An expedition to the island led by paleontologist Professor Kyohei Yemani soon discover something more devastating than imagined in the form of a 164 foot tall monster whom the natives call Gojira. Now the monster begins a rampage that threatens to destroy not only Japan, but the rest of the world as well.

Humanity’s desperate battle to reclaim the Earth from Godzilla continues. The key to defeating the King of the Monsters may be Mechagodzilla, a robotic weapon thought to have been lost nearly 20,000 years ago.

With no means for defeating Godzilla Earth, mankind watches as King Ghidorah, clad in a golden light, descends on the planet. The heavens and earth shake once again as the war moves to a higher dimension.

After the appearance of a new Gojira (Godzilla), the Japanese government builds a robotic Godzilla from the bones of the original monster that attacked Tokyo in 1954 to stop the beast.
