Hailing from the planet Devaron, the Devaronians were a species of sentient humanoids, characterized by two legs, a torso, a single head, two arms with hands, fingers, and an opposable thumb. The species had two sexes, male and female. Known Devaronian skintones included reddish brown and green.

The Devaronian head featured a nose, a mouth, and two forward-facing eyes, which notably came in shades of red, purple, and dark brown. Both sides of the face were flanked by two pointed ears that stuck out slightly. The males had short horns growing from the top of their heads. The females, however, were hornless, but had two dark circles above the forehead, where the horns usually are in males. While females had a full head of hair, males were bald some of them, however, grew sideburns.

Under the reign of the Galactic Empire, a Devaronian named Cikatro Vizago led the Broken Horn Syndicate, a Lothal-based criminal organization. The crew of the starship Ghost occasionally relied on Vizago for funding and information. Another Devaronian named Yelkin worked as a miner on the thorilide mines of Cynda. Shortly before the Battle of Yavin, a red-skinned male Devaronian was present in the cantina of Mos Eisley the day Obi-Wan Kenobi and Luke Skywalker met Han Solo and Chewbacca.
