Aurora Unit 486 is an Aurora Unit who helped terraform Norion into the "fertile planet it is today". It is mentioned in Metroid Prime 3: Corruption in the Galactic Federation Data entry "Planet Norion", but is not seen in-game, although it is possibly located somewhere on Norion. Whether 486 was cured of its corruption virus infection prior to the start of the invasion on Norion, or was one of the AUs still needing the cure, is also unknown. It can be presumed that 486 would have received the cure regardless. 486 is the only named Aurora Unit in the Metroid series that has yet to be encountered by Samus.
