Hedorah was named for hedoro, the Japanese word for mud. This is especially befitting, due to most of Hedorah's attacks involving releasing acid-rich dirt at his opponent. Hedorah is commonly referred to as the Smog Monster (公害怪獣?), a reference to his habit of both consuming and producing numerous gaseous pollutants, and is referred to as such in the American dub for Kōgai KaijūGodzilla vs. Hedorah. In the trailer for Godzilla vs. Hedorah, he was instead given the title Ninja Monster (忍者怪獣?). Ninja Kaijū
Hedorah's first three forms are denoted as Aquatic Stage (水中棲息期?), Landing Stage Suichū Seisoku-ki (上陸期?), and Flying Stage Jōriku-ki (飛行期?). His final form is known as either the Perfect Stage Hikō-ki (完全期?) Kanzen-ki, Mature Stage (成長期?) Seichō-ki, or the Giant Stage (巨大化期?). Kyodai-ka-ki
In its first form, Hedorah resembled a tadpole. In its second form, it resembled a quadrupedal reptile. Its third form was like a flying saucer, and its final form took on a humanoid shape. Hedorah's forms all share multiple common characteristics - all have green, kelp-like surfaces and large, yellow eyes with red irises. These eyes are positioned so that they blink sideways.
According to an interview with Yoshimitsu Banno by the Japanese magazine Eiga Hi-Ho, Hedorah's eyes were modeled after vaginas. In his Godzilla: Final Wars design, this allusion is significantly toned down, and his eyes were tilted, thus appearing to have a more 'normal' appearance.
In Godzilla vs. Hedorah, Godzilla tears out two white orbs from Hedorah's body. While in the film, the purpose of these orbs is never discussed, supplementary materials explain them to be Hedorah's eyeballs, despite them being white instead of red.
Hedorah seems to be primarily driven by instinct and the will to survive, and the horrific death and destruction he causes are mostly derived from his bizarre biological properties rather than any true malice. However, he does demonstrate aggression and awareness in his encounters with Godzilla. When first confronted by Godzilla, Hedorah answers Godzilla's taunts and seems to even mimic his gestures. During the monsters' final battle, Hedorah even laughs while smothering Godzilla in sludge.
In Godzilla: Final Wars, Hedorah was under mind control and did not act independently. His only visible onscreen actions involve him being blasted out of Tokyo Bay, then visibly waving his arms and panicking before Ebirah's claw pierces his eye.
In the comic series Godzilla: Ongoing, Hedorah is aligned with the other space monsters, and seems to be intentionally causing destruction.
In the Showa series, Hedorah was an alien life form from the Dark Gaseous Nebula in the Orion constellation that landed on Earth traveling on a comet for at least 243 light years. In Godzilla: Final Wars, Hedorah was one of many monsters under the control of the Xiliens, but his origin and how he came under the Xiliens' control are never explained.
HistoryDark Gaseous Nebula of the Orion, landed on Earth during the arrival of a comet, and promptly began feeding on pollution. Hedorah's actions soon gained the attention of Godzilla, who attacked the Smog Monster as he was literally sucking on an active smokestack to consume the pollutants being given off by it. At the time, Hedorah was smaller than Godzilla and inexperienced at fighting, 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 as he continued to feed. 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, the JSDF had built a pair of gigantic electrodes near the warring monster. Since Hedorah was an amorphous being and thus was mostly fluid, it was hoped that the two electrodes would dry Hedorah out and defeat him. Unfortunately, during the battle the fuses to control the electrodes had blown and the pylons supplying electricity had been damaged by the two monsters, making the electrodes useless.
Despite his brutal injuries, Godzilla recovered enough energy to stand up, and powered the electrodes with shots of his atomic breath before resuming the battle, dragging Hedorah back towards the electrodes. Badly dehydrated by the devices, Hedorah fled using his flying form, but Godzilla used his atomic breath to fly after him. After knocking Hedorah down, Godzilla brought Hedorah back to the electrodes and had them near-completely dry Hedorah out. Realising Hedorah might still have moisture within him that could bring him back to life, Godzilla tore into Hedorah's body and had the electrodes dry out the remaining husk of Hedorah, reducing him to a mass of dust and finally defeating the alien.
At the end of the movie, a picture of another Aquatic Hedorah is seen in some water, with the caption 'And yet another one?', but no sequel to the film was produced.
The Hedorah in Godzilla vs. Hedorah killed thousands of people. Hedorah killed some of the oil tankers' crew mates, most of the swimmers and fish in the sea, about 40 people on the first time he went on land, 1600 people when it was first flying, an unknown number when he was flying to Mount Fuji and about 80 of the people who were partying on Mount Fuji. Also, over 3,000,000 people were affected by Hedorah's smog. Strangely enough, it is not shown in the Millennium series whether Hedorah kills any people at all.Godzilla Island. He attacked Mothra and managed to injure her, but was dehydrated by Godzilla.
There was also another Hedorah in Godzilla Island called Neo Hedorah.
Hedorah is one of the strongest opponents Godzilla faced in the Showa series (though Godzilla easily defeated Hedorah in Godzilla: Final Wars, which means that either the Millennium Hedorah is much weaker than the Showa version, or that the Final Wars Godzilla is far more powerful than the Showa one). Hedorah possessed many special abilities. Hedorah's primary form of attack was by squirting chunks of its own acidic body at its opponent, as well as a red laser beam from its eye, capable of setting objects on fire and burning the flesh off any opponent it strikes. In its saucer form, it was also able to fly, and spread a mist of sulfuric acid as it went along, and in its final form it could revert back to its flying form at will. Hedorah can combine with other Hedorahs to become larger, or divide into multiple smaller Hedorahs. Hedorah does not require oxygen to survive, but rather thrives on inhaling toxic pollutants. The byproduct of Hedorah consuming these pollutants is a highly concentrated sulfuric mist, which is capable of corroding any metal and completely disintegrating organic life.
Hedorah is shown to also be able to release massive quantities of sludge and dirt without this affecting his size in any way, as shown in Godzilla vs. Hedorah where he traps Godzilla in a pit and releases so much sludge into the pit that it nearly covers Godzilla.
Hedorah has strong defenses, as it was completely immune to Godzilla's atomic breath even in its comparatively weak second stage, and conventional weapons would merely pass straight through Hedorah's amorphous body, leaving the pollution kaiju unharmed. Tearing into Hedorah's body proved to be ineffective as well, and it resulted in the flesh on Godzilla's hand dissolving all the way down to the bone, as Hedorah's blood alone is very toxic. Only his eyes are known to be affected by his own liquid sludge, and when he bleeds over one of his eyes, he has to shut the eye to prevent it from being damaged. In the ending credits of Godzilla: Final Wars, Hedorah is shown spraying sulfuric acid mist from tubes on his body, while stomping through city ruins. In Godzilla: Final Wars, Hedorah was also given a whip-like arm, which he may or may not use in battle.
While Hedorah was ultimately unable to kill Godzilla, his attacks are still incredibly effective against him, and Hedorah came close to killing Godzilla several times during the course of their numerous battles. Hedorah's toxic sludge alone was capable of burning Godzilla's armored flesh, and even cost Godzilla his eye. Hedorah's blood was able to actually burn all of the skin and and flesh off Godzilla's hand. As a result, Hedorah was the first kaiju to ever visibly penetrate Godzilla's skin. The sulfuric mist given off by Hedorah's flying form was also capable of causing Godzilla to gasp for air and collapse.

Hedorah appears as a villain in the 1988 Nintendo game Godzilla: Monster of Monsters, as well as the sequel, Godzilla 2: War of the Monsters. Hedorah was an enemy in Gojira-kun and the Godzilla Gameboy game as well, and was unique because Godzilla's blows couldn't hurt him, but rather push him back somewhat.
Hedorah also makes an appearance in Godzilla: Destroy All Monsters Melee, where it randomly appears in disc form and slows the energy recovery. It can be killed, though this is difficult. When it is killed, it turns into a puff of smoke which dies away.
Hedorah was stated to appear in both of the Godzilla: Destroy All Monsters Melee sequels but for Godzilla: Save the Earth, the game's engine couldn't develop a skeleton for Hedorah since it is a gelatinous blob, and for Godzilla: Unleashed, the cel-shading was a long and complicated process so Pipeworks decided to scrap him.
Hedorah appears for the first time as a playable character in the PS4 version of Bandai Namco's Godzilla, and as an enemy monster in the PS3 version. He is one of the lower tier characters, and can be fought on any difficulty path.

While Hedorah doesn't appear in this two-volume manga's main story, he appears as Godzilla's opponent in the Street Fighter Godzilla story, placed at the end of Volume 2. In this short story, Hedorah is dressed up as Blanka from the Street Fighter series, while Godzilla is dressed up as Ryu. Hedorah fights Godzilla with his red beams, but gets sent flying by a Shoryuken from Godzilla.
Godzilla: Ongoing, Hedorah is one of the space monsters that attacks Earth, the others being Gigan, SpaceGodzilla, and Monster X. Hedorah does battle with Kiryu and almost destroys him, but Godzilla arrives and takes on the smog monster while Kiryu escapes to get backup. Hedorah badly wounds Godzilla with his deadly toxic body and knocks him into a canyon, where he attempts to drown Godzilla in toxic sludge. Godzilla uses his atomic breath to fly out of the canyon and resumes his battle with Hedorah. Godzilla tears Hedorah into pieces and burns him into dust with his atomic breath. Godzilla then leaves to battle the other space monsters, leaving Hedorah apparently destroyed.
Hedorah appears in The Half Century War #3 as one of the many monsters battling in Ghana in 1975.
Hedorah in Godzilla: The Half-Century War #3
Hedorah appeared in the final issue of Godzilla: Oblivion, where he emerged from an interdimensional portal alongside Anguirus, Rodan, Zilla, King Caesar, Biollante, and Mothra and her larvae as entered the battle between Mecha-King Ghidorah and Godzilla. After causing some destruction in the city, Hedorah challenged Godzilla following the latter's victory over Mecha-King Ghidorah, only to be dispatched by a blast of atomic breath. Later, all of the monsters were left behind as the humans left the Earth as it became covered by tiny robotic cells that served as interdimensional doorways.

Hedorah's gurgling roar comes from Kemular, a poison gas monster from the original Ultraman series. When feeding on toxic fumes, Hedorah makes breathing noises that are recycled from Gezora. In addition, he utters several high-pitched laughter-like sounds, mostly in his final form. In Godzilla: Final Wars, his roar mostly remains the same, but he also emits sounds that are similar to an elephant trumpeting that has been lowered in pitch, and his roar now echoes.

- The sound effect used for Hedorah's eye beams is the same as the one used for Showa King Ghidorah's flying, only played at a higher pitch.
- In both of Hedorah's film appearances, his left eye is injured in some way.
- Hedorah is one of the first Toho monsters to be depicted via hand-drawn animation, as seen in the animated segments of his debut film.
- In Godzilla: Final Wars, Hedorah's tail resembles the Choju King Crab's from Ultraman Ace.
- Hedorah's blood is very toxic and acidic, but the only part of his body which is vulnerable to it is his eyes. If Hedorah bleeds over his eyes, he has to close them to prevent them from being damaged. However, in Godzilla vs. Hedorah, Hedorah used this to his advantage, after Godzilla punched through one of his eyes, the acidic blood caused the flesh on Godzilla's hand to be burned off down to the bone.
- Hedorah was the last new monster in the Showa era to completely act on its own independence, as the rest were controlled by aliens.
- It is almost impossible to kill Hedorah, as his only weakness is dehydration.
- It is never explained whether Hedorah is on the side of the Xiliens in Godzilla: Final Wars, or if he simply arrived on Earth to feed on the pollution given off by Tokyo.
- The end of Godzilla vs. Hedorah shows one of Hedorah's tadpole forms is still alive, alluding to a sequel that was never made.
- Due to Hedorah's very brief appearance in Godzilla: Final Wars, he carries out the least on-screen destruction in the entire film, as he was only shown feeding on the pollution in Tokyo Bay before Godzilla attacked him. The footage showing him using his sulfuric mist suggests that he was to have more screentime in the film, but that it was cut as a result of time constraints.
- In Godzilla: Final Wars, Hedorah's theme was cut from the movie's soundtrack along with his fight with Godzilla.
- Hedorah's debut in Godzilla vs. Hedorah coincided with the revival of the Ultraman series with The Return of Ultraman. Curiously, the first episode of the new series featured a monster called Zazahn, a kelp monster bearing a remarkable likeness to Hedorah who was supposedly attracted to a city by pollution. Curiously, the episode which featured the debut of Zazahn was also directed by Ishiro Honda.
- Hedorah was likely an inspiration for the monster Destoroyah in Godzilla vs. Destoroyah. Both monsters possess multiple forms, including microscopic, flying, and gigantic bipedal final forms, are composed of trillions of microorganisms that have merged together, are extremely difficult opponents for Godzilla, and are incredibly deadly to organic life. Both Hedorah and Destoroyah likely influenced the creation of the monster Shinomura from the comic Godzilla: Awakening, which also shares many of these similarities.
- In Bandai's 1984 Godzilland merchandise line, Hedorah is depicted as a female monster and one of Godzilla's friends. The Godzilland Hedorah is generally purple in color with long eyelashes above its eyes. This is the only known instance of Hedorah being portrayed as an ally or friend of Godzilla.
