The Ubarrak are a humanoid civilization native to the Alpha Quadrant. They control a multi-sector-spanning interstellar empire known as the Ubarrak Primacy. The Ubarrak have slitted yellow eyes and prominent overhanging brow ridges. Individuals have been described as "powerful" and "broad-shouldered", but it is unclear whether those were general traits or just qualities of those individuals. Ubarrak can hold their breath for several minutes. They are prone to scanning their environment with tiny jerks of the head, as if expecting trouble at any moment.
