History: An alien monster, presumably unknowingly brought to Earth by the Nebulans, began feeding on the rampant pollution on Earth. The pollution was so abundant that it grew to incredible sizes, progressing through its four-stage life cycle. As it feeds and grows, it comes into conflict with Godzilla three times, once in its terrestrial form, once in its flying form, and finally near Mt. Fuji for their final battle. The battle is fierce, with Godzilla suffering a number of injuries from the toxic monster. Hedorah is only finally defeated with the help of the human-made giant electrodes, which Godzilla activates with his breath, causing the smog monster to dry out and die.

Species: Alien Hedrium lifeform
Origin: Tokyo Bay
Faction: Xiliens
Abilities: Acidic Sludge, Sulfuric Acid Mist, Red Melting Ray, Division, Recombination
History: This male Hedorah is an alien monster that first appeared sometime between 1996 and 1999. It was later controlled the Xiliens who deployed it to Tokyo Bay along with Ebirah to try and destroy Godzilla, but the king of the monsters easily defeated the two.
Species: Hedrium lifeform
Origin: Heibei
Faction: China, Destroyer
History: A pollution eating bacterial lifeform discovered in a cave in Heibei, China that was turned into a bioweapon by the Chinese. When Anguirus I and Rodan I appeared in Beijing, Hedorah was deployed to destroy the monsters. While the plan was a success, Hedorah went wild and destroyed Beijing and Tianjin overnight. Once the monster ran out of pollution to digest, it disappeared. It is likely that Hedorah was originally brought to Earth along with the organic Gigan sometime in Earth's past, presumably 12,000 years ago.
