Showa Hedorah
Showa Hedorah, also known as the Smog Monster, is a kaiju that first appeared in the 1971 film "Godzilla vs. Hedorah." It was created as a result of pollution and industrial waste, and its main goal was to destroy human civilization. Hedorah had the ability to change forms, from a small, slug-like creature to a giant, dragon-like beast with poisonous gas emitting from its body.
