Godzilla: The Series - Season 2 - Eps 15: Vision
Another new and dangerous mutant species appears on the scene, this time in the form of gigantic hummingbirds that attack planes flying over San Francisco. Worst of all, this mutant avian species is able to render themselves invisible via the hummingbird trait of flapping their wings faster than any other bird species in the world. As a result of their ability to cloak themselves so as to be invisible to the unaided eye, Godzilla is unable to see the creatures in order to attack them.
