Legendary Orga

Legendary Orga origin:

Orga was part of a species of microscopic organisms that absorbed other microbes for nutrients. This species did not orignate from Earth; their origin is unknown.

After many years on the radiation-enriched Earth, the organisms evolved into a multi-cellular beasts who still consume other creatures for nutrients, also gaining their essence. By unhinging it's massive, venomous maw and devouring its prey, an Orga is a deadly creature indeed. This feeding ability enabled the Organisms to live far after the other radiation-feeding animals.

Orgas are very strong and intelligent creatures. They are loners and do not work in groups due to their territorial nature. The Orga species are smart enough to create a "seperate brain" from parts of their bodies and is protected by the Orga's regenetive skin. This second brain holds knowledge of past lifeforms the Orga absorbed, and is telepathically controlled by the owner to follow them. The goal of the Orga is to gain knowledge, in order to become the dominant species. However, they were rivals of Godzillas, who were strong enough to keep the Orga population relatively small.

However, during the Ice Age, large animals were very rare, and the Orga's started to die off, except one...

This Orga was the only one of it's species to survive because it consumed a Godzilla, gainging it's endurance and strength. It remained dormant deep in the ocean depths, along with it's second brain, until large creatures began to arise due to the Nuclear Bomb testings. The "Alpha Orga" emerrged from it's hibernation, for it was hungry.
