Kenpachirō Satsuma

After a fishing boat is attacked, the sole surviving crew member realizes it is none other than a resurrected Godzilla. However, efforts to bring the story to light are suppressed by the Japanese government amid growing political tensions between the United States and the Soviet Union, who are both willing to bomb Japan to stop the monster.

An ever evolving alien life-form arrives on a comet from the Dark Gaseous Nebula and proceeds to consume pollution. Spewing mists of sulfuric acid and corrosive sludge, neither humanity nor Godzilla may be able to defeat this toxic menace.

Mothra's dark counterpart, Battra, emerges to eliminate humanity on behalf of the Earth. Two tiny fairies called the Cosmos offer their help by calling Mothra to battle the creature. Unfortunately a meteorite has awoken a hibernating Godzilla as a three way battle for the Earth begins.
