Hedorah (ヘドラ Hedora) is an alien pollution kaiju created by Toho that first faced Godzilla in the 1971 Godzilla film, Godzilla vs Hedorah.
Hedorah, an alien from the Dark Gas Nebula, landed on Earth began feeding on pollution. Hedorah's actions soon gained the attention of Godzilla, who attacked the Smog Monster as he was feeding off of a smokestack. At the time, Hedorah was still in a young form, and was easily trounced by Godzilla. The two creatures had a series of battles across Japan, and Hedorah continued to grow bigger and stronger, and achieved a flying saucer-like form, allowing him to fly and spread sulfuric acid mist across Japan while destroying many factories. Hedorah and Godzilla had a final showdown near Mount Fuji, in which Hedorah achieved his final form, a humanoid, walking pile of sludge. Thanks to his acidic, poisonous body, as well as his lethal eye bolts, Hedorah very nearly put an end to Godzilla in their struggle. However, mankind had built a pair of gigantic electrodes near the warring monster. Their plan was that, since Hedorah was merely sludge, they would use the electrodes to dry him out. During a period of the fight where Godzilla was knocked out, Hedorah was lured between the electrodes. Unfortunately, a fuse was blown, and the electrodes were useless.
Thankfully, Godzilla quickly came to the rescue again, using his ray to re-energize the electrodes. Badly dehydrated by their electricity, Hedorah tried to escape, but thanks to Godzilla's new-found power of flight, was returned to the electrodes and was dried out completely. Sensing that there was still wet sludge within Hedorah's dried out husk, Godzilla proceeded to rip out Hedorah's innards, then used the electrodes to fry them. Godzilla had finally killed Hedorah, but not without a price; he had lost one of his eyes, and his right hand was burnt down to the bone.
