The Rigellians hailed from Rigel VII and were characterized as massive, green-skinned sentient humanoids. Their reptilian physiology, shaped by the intense gravitational forces of their native planet, resulted in a dense, heavily-muscled build and a large frame. This unique adaptation granted them exceptional strength on planets with standard gravity, where they were said to be capable of dismantling vehicles and other metallic structures. Their considerable physical capabilities led to their occasional employment as assassins. By the era of the Galactic Civil War, the Rigellian species was nearing extinction. A member of this species was the bounty hunter operating under the guise of Darth Vader's porter.
