Zabraks were a species of near-humans that had evolved to be tough due to the nature of their homeworld Iridonia. The species was carnivorous and had two hearts, which allowed them to pump oxygenated blood around their systems more quickly than other species meaning they could run faster and physically exert themselves for longer. Some Zabraks possessed a ring of small, vestigial horns that ran from high on their brow round to the back of their head. The horns of males were generally more developed than those of females, although horn placement, length, and thickness varied enormously across the species.

Zabraks could be Force-sensitive.There were two subspecies of Zabraks, the Dathomirians and the Iridonians. Female Dathomirians did not have any horns, but males did.

All Zabraks were fiercely independent, usually taking on roles in society that minimized their need to be ordered around by others. This was often mistaken by other species for aloofness or arrogance, which was erroneous, although Zabraks were unashamedly proud of being survivors. The majority of Zabraks wore facial tattoos which often indicated familial ties, but could also simply be based on an individual’s personal taste. They were a colonial species, having migrated and adapted to dominate many worlds. The Zabraks of Iridonia were commonly seen traveling across the galaxy as Jedi, bounty hunters, or in other professions. A group of tribal male Zabraks lived on the planet Dathomir, where they were subservient to the female Nightsisters, but dwelt separately from them. Much of the Dathomirian Zabraks’ culture was unknown to outsiders, as they did not trust offworlders.
