Fairy Mothra

While in space, Mothra spawned thousands of Fairy Mothras, and one was sent to Earth to deliver a message from the Cosmos. In a park, Miki Saegusa was thinking about Project T, a plan which she wasn't sure of, which aimed to control Godzilla with her psychic powers. Just then, a nearby tree's leaves started glowing, and so did her earrings, which had the symbol of the Cosmos. From the tree came out a Fairy Mothra. The Fairy Mothra transformed into a projection of the Cosmos, who told her that SpaceGodzilla was going to try to kill Godzilla, and wanted her to somehow help defeat this monster. The Cosmos disappeared, leaving Miki, who now thought it was necessary to join the project.

Fairy Mothra appeared later when Miki was on Birth Island. The Cosmos warned her that everyone needed to work together to defeat SpaceGodzilla. After SpaceGodzilla was defeated, Fairy Mothra came back again. The Cosmos thanked Miki for saving the world, and Fairy Mothra returned to outer space.
