Hedorah

, also known as 'The Smog Monster, is a Kaiju who first appeared in the 1971 film Godzilla vs Hedorah. An extraterrestrial Kaiju that is Formed out of pollution, which it also consumes, Hedorah utilises Poison, sludge and smoke to attack, but is ultimately defeated by Godzilla's Atomic Breath attack.

In M.U.G.E.N, has been made only once, by Kozenikan. Closely following its behaviour in the movie, Hedorah fights by using Poison, sludge and smoke. The sprite for Hedorah was ripped from the 1980s NES Game Godzilla: Monster of Monsters!

Hedorah is as expected, slow. However, its attacks have quite decent range.
