Godzilla: The Series (1998)

S2E9 Metamorphosis

Title: Metamorphosis Plot: H.E.A.T. is on the case of a colossal caterpillar mutation dubbed the Megapede, wreaking havoc across Illinois and Indiana. In response, Godzilla is summoned for aid, but the Megapede counters with a toxic foam and venomous spurs on its numerous legs, keeping the King of the Monsters at bay. Ultimately, the giant insect ascends a skyscraper, encases itself in a cocoon, and emerges as a massive winged creature that disrupts radar signals by rubbing its wings, causing chaos. To combat this threat, H.E.A.T. develops a foam that neutralizes the creature's toxins, enabling Godzilla to more effectively confront and defeat the beast.
