The first inhabitants of Universal Federation are referred to as Aborigines.  The female pictured is portraying the aboriginal tribe called the Skull Gods.

The Skull Gods were the first to tattoo their bodies in allegiance to their tribe.  They tattooed black circles around their eyes and the rest of their face was white except for their black nose.  Their bodies were tattooed to resemble their actual bones.  As the years went on, the females began decorating their faces with floral patterns and different colored motifs.

The other aborigine tribes were the Red Crows, Battle Claws, Shadow Beasts, and Wild Broncos.
