Height: 0.1mm ~ 60m
Weight: 0-48,000tons Birthplace: Space
Appearance: “Godzilla vs. Hedorah”


A mysterious creature that adheres to meteorites and comes from space. It has the opposite properties of creatures on earth. Its body is composed of space minerals called “hedrum.”


At first, it looks like a tadpole and lives in the contaminated sea, but it repeatedly coalesces cells, passes through the Umibozu type, and finally lands on two legs.

Umibōzu​ is a spirit in Japanese folklore. The Umibōzu is said to live in the ocean and capsize the ship of anyone who dares speak to it. This spirit’s name, which combines the character for “sea” with the character of “Buddhist monk,” is possibly related to the fact that the Umibōzu is said to have a large, round head, resembling the shaven heads of Buddhist monks. Alternatively they are enormous Yōkai that appear to shipwreck victims and fishermen. (Source: Jisho)

さらに円盤状に形態を変化させ、空を飛ぶようになり、最終 的にはゴジラを上回るほどの大きさにまで成長する。食性は水 銀、コバルト、カドニウムなど地球生物にとって、有害なものであれば何でも食べてしまう。

Furthermore, it changes its shape into a disk shape, and it will fly in the sky, and eventually it will grow to a size larger than Godzilla. Its eating habits involve eat anything harmful to the earth’s organisms, such as silver, cobalt, and cadmium.

武器は、成長の段階でやや異 なり、水中棲息期には体当たり攻撃を得意とする。また、上陸 期には有害物質を多量に含んだヘドロ弾を発射。飛行期には滑空しながら、硫酸ミストなどを噴射する。巨大化期には体内で起こる核反応を利用し、眼球の上部から赤色の怪光線を発射するようになる。

Weapons are slightly different at the stage of growth and are good at ramming during the underwater inhabitation period. Also, during the landing period, Hedorah projectiles contain a large amount of harmful substances were fired. During flight, it glides and injects sulfuric acid mist and the like. During its enormous period, it uses the nuclear reaction that occurs in the body to emit a red mysterious ray from the upper part of the eyeball.
