Mothra

Mothra (モスラ Mosura) is giant divine moth kaiju that appeared in 1961.

Origins
Mothra is the guardian goddess of the remote Infant Island in the south Pacific Ocean. She is reborn through an egg and is worshiped by the island's natives. She is spoken for by two miniature telepathic fairies called the Shobijin. Mothra is a type of Japanese silk moth which evolved as a byproduct of climate change on Infant Island due to increasingly abnormal weather patterns on Earth.
