Insectosaurus was a one-inch grub transformed by radiation into a 350-foot monster that attacked Tokyo. She was captured in 1969 and formed a close bond with the Missing Link, who is the only person that can understand her (although he nonetheless erroneously believed her to be male). After spending almost four decades in her larval phase (presumably due to the effects of the radiation inducing her gargantuan size), Insectosaurus metamorphosed in the late 2000s into a similarly-enormous butterfly who, despite her immense mass, was capable of powered flight.
Physical Appearance
Originally, Insectosaurus was nothing more than a simple grub with no unique characteristics, but after her mutation, she donned an almost mammalian-like appearance similar to that of an orange hamster with a massive overbite, four pincer-like arms, antennas, two stubby feet, and a short reptilian-like tail.
Insectosaurus is a massive creature in size, even dwarfing the giant Ginormica. After her metamorphosis near the end of the film, Insectosaurus' appearance is changed to that of a more moth-like creature (similar to Mothra of Godzilla fame) while still possessing her hamster-like face, furry body, massive overbite and reptilian-like tail.
