Jovians are a species of shapeshifting biomorphs hailing from Jovia XII, the source of Jovian steel. Their description indicates they are similar to the late bounty hunter Gandrayda, who may be a member of this species. It is unknown whether or not they have a treaty with the Galactic Federation that allows the latter to mine Jovian steel, which is used in the construction of the Sector Zero base on Norion.

The Jovians are never named as such in Metroid Prime 3: Corruption; they are only described as "shapeshifting biomorphs". As Jovian steel is said to have been derived from Jovia XII, it can be assumed that Jovian is the proper name for this species.
