1992's "Godzilla vs. Mothra" portrays Mothra as a guardian of the Earth who presided over an advanced civilization over 12,000 years ago. When the civilization created a device designed to control the Earth's climate, the Earth responded by creating the Black Mothra, Battra – which Mothra defeated, but not before the civilization was wiped out. Mothra's egg is later discovered in 1992 on Infant Island by the Marutomo real estate agency, which seeks to exploit it and Mothra's priestesses for profit. The egg hatches during a fight between Godzilla and a resurrected Battra, and the larva later attacks Tokyo in order to save its priestesses. Mothra forms a cocoon around the National Diet Building, attains its adult form, then briefly fights Battra before joining forces with him in order to fight Godzilla. Battra dies in the attempt and Mothra pledges to fulfill Battra's role in preventing a meteorite from devastating the Earth in 1999.
