Rebirth of Mothra

Millions of years prior, a giant three-headed space dragon called Desghidorah arrives on Earth and battles a species of enormous and highly advanced moths who serve as protectors of the "Elias", a race of tiny, humanoid beings. After the battle, Desghidorah is defeated and sealed under the Earth while three Elias, the benevolent Moll and Lora and the vengeful Belvera, and one moth, Mothra, remain.
