Trandoshans (T'doshokin their language) were large, bipedal reptilian humanoids from the planet of Trandosha (or Dosha). They had sensitive eyes that could see into the infrared range and the ability to regenerate lost limbs—albeit slowly—and were anatomically built heavier and stronger than most humanoids, including Humans. They would also periodically shed their skin. Unlike some other reptilian humanoids, such as the Barabels and the Ssi-ruuk, Trandoshans had no tails. The Trandoshans were a warlike species who allied early with the Confederacy of Independent Systems and the Empire, taking Wookiees as slaves.
As a species, they were renowned across the galaxy for great strength. This is evidenced by several members of other species boasting physical prowess and power by having defeated a Trandoshan, either in battle or in a contest of strength.
