After the radioactive storms on Sollgel Island transformed the man-sized Kamacuras to giants, the world was stunned to see the insects descend on a small mountain and unearth a mammoth egg. The mantis creatures immediately smashed the shell, revealing within an infant Godzilla. The ravenous insects were about to gorge on the helpless Minilla, when Godzilla stepped in, blasting the creatures into full retreat. Then, in an act of benevolent heart, Godzilla adopted the baby as his own. Teaching the growing Minilla how to belch its fires and survive on the harsh lands. However, their survival was put to the test when the gigantic black spider, Kumonga, crawled from the brush. Only under the combined flames of each monster did they burn the vile existence of the arachnid away.
