Jovian from metroid series only appeared in prime image - FIN7

Jovians are a species of shapeshifting biomorphs hailing from Jovia XII, the source of Jovian Steel. 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, or if the Federation came and took it by force.
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.
