Space Silverfish

The Space Silverfish are extraterrestrial insect kaiju created by Toho and appear as recurring antagonists in The Dawn of Monster Kid.

Origin
The Space Silverfish are alien creatures that drifted through space on solar winds in pod-like meteorites to search for an inhabitable planet for populate their species. Whatever planet they arrive, the male would run away while the female chases him. Once they mate, the female lays 50 eggs and when the juveniles hatch, they would eat whatever they see.
