Millennian

The Millennians (ミレニアン, Mirenian?) (from Godzilla 2000: Millennium, 1999) were a race of beings that, while traveling in space in their solar-powered spacecraft, crashed on Earth in the Cretaceous Period, and were reduced to anti-matter. In the year 1999, a submarine built by the Crisis Control Intervention Center (CCI) accidentally awakened it from its 65 million year old slumber by shining the submarine's lights on it. The revived Millennians needed a way to regain their physical form. Scanning a group of humans, they found their DNA insufficient, and so their saucer flew off to find DNA that met their needs. They found this DNA in Godzilla, who was just attacking Tokaimura. Scanning Godzilla, the Millennians found his eternally reproducing cells (dubbed "Organizer G-1", "Regenerator G-1" in the American version) to be ideal for their ambitions. The saucer attacked Godzilla with a powerful energy cannon, but when Godzilla returned fire with his fiery, powerful plasmatomic energy beam, the fight ended up in a double knock-out. The CCI tried to contain the saucer, but it easily broke free from its bindings and flew off, landing in Shinjuku. There, it began remotely absorbing any information it could from computers throughout the city.

When Godzilla arrived in Shinjuku to destroy his foe, the saucer was able to overwhelm him, knocking a massive skyscraper onto him and rendering him unconscious. While Godzilla was out, the saucer extracted a large amount of his DNA and began using it to take form. The Millennians took form as a single, gigantic squid-like creature. Unfortunately, the Millennian could not control the power of Organizer G-1, and began mutating much further than it had expected. The creature collapsed to the ground as the DNA changed its body. As this was happening, Godzilla regained consciousness and blasted the saucer out of the sky. As Godzilla moved in towards the wreckage to investigate, the Millennian stood up, revealing its new form - the monstrous Orga. Startled by the new creature's sudden appearance, Godzilla went on the attack.

As the Orga, the Millenians acquired massive physical strength and the ability to fire a beam of energy similar to that of their spaceship from its right shoulder. They also gained the ability to assimilate an opponent's DNA by biting them.

The Millennians pilot the saucer using telepathy, which it also uses to tap into all technological devices, including computers, to gather their data, as well as transmit messages on all media machines. It also used telepathy to lasso Godzilla with underground cables, so that the alien can wear out the monster in order to gain the Organizer G-1. The Millennian also seems to not want to fight unless absolutely necessary; even once it has mutated into Orga, it is obvious that it does not want to battle Godzilla until it realizes that escape is not an option

Planet
The atmosphere is very different from Earth's, most species won't survive on our world from this planet.
