Orga (Godzilla)
From Multiversal Omnipedia
Orga was an alien entity, first appearing as a long-buried spacecraft, which awoke in the early 21st century and began gathering data. Targeting Godzilla for his regenerative G-cells, the spacecraft attacked, assimilating some of Godzilla's DNA and becoming a pseudo-reptilian creature. Although a match for Godzilla, the kaiju was finally able to destroy Orga with atomic fire.
Comments
The creature was never named in the film Godzilla 2000, but it was named in other materials, such as the Godzilla: Destroy All Monsters Melee video game.
