In the Daikaiju Universe

 * Two small fairies called the Shobijin are discovered on the irradiated Infant Island, and are stolen. Their monster god Mothra hatches and crawls to Tokyo to save them. The giant larva then builds a cocoon and transforms into it's adult form. It then finally locates her small priestesses and takes them back to Infant Island. (Mothra)
 * A young sea monster named Gorgo is awoken by volcanic eruptions off the coast of Ireland. He is taken away by humans to London, only to have his mother, Ogra, travel across England to look for him. After she destroys most of London, she is reunited with her son, and the two leave peacefully. (Gorgo)
