Although he did not return as director, Ōmori continued his trend of incorporating Hollywood elements into his screenplay, in this case nods to the Indiana Jones franchise.

Later, a representative of the Japanese Prime Minister offers to have Takuya's charges dropped if he explores Infant Island with his ex-wife, Masako Tezuka and Kenji Ando, the secretary of the rapacious Marutomo company.

Battra, a male divine moth with a ferocious appearance that vaguely resembles Mothra, destroyed the civilisation and their weather-controlling device but then became uncontrollable, and started to harm the very planet that created him.

The Cosmos explain how the meteoroid uncovered Mothra's egg, and may have awoken Battra, who is still embittered over humanity's interference in the Earth's natural order.

Masako and Takuya later discover Ando's true intentions when he kidnaps the Cosmos and takes them to Marutomo headquarters, where the CEO intends to use them for publicity purposes.

Both Mothra and Battra attain their imago forms and converge at Yokohama Cosmo World where they begin to fight once more.

The next morning, the Cosmos explain that Battra had been waiting many years to destroy an even larger asteroid that would threaten the Earth in 1999.

Mothra had promised she would stop the future collision if Battra were to die, and she and the Cosmos leave Earth as the humans bid farewell.

However, the site of their fall would have been the submerged, Stonehenge-like ruins of the Cosmos civilization, which would have engulfed and trapped Godzilla with a forcefield activated by Mothra.

"[15] Stomp Tokyo said the film is "one of the better Godzilla movies in that the scenes in which monsters do not appear actually make some sort of sense.

"[16] Mike Bogue of American Kaiju said the film "[does] not live up to its potential", but added that "[its] colorful and elaborate spectacle eventually won [him] over" and "the main story thread dealing with the eventual reconciliation of the divorced couple adequately holds the human plot together.
