Devaronian / Legends Devaronians were a horned humanoid species from the world of Devaron in the Colonies , a planet of low mountains and deep valleys linked by thousands of rivers . It was believed that they were descended from a race of primates that lived in the mountains of Devaron , and that their horns were a genetic mutation that proved useful in fending off predatory birds . Biology and appearance . A bipedal mammalian species , Devaronians evolved in the dense jungles of Devaron as a hunter - gather species . Their bodies were denser than most humanoids ' and as a result they were heavier than their appearance would tend to indicate . Devaronians had silver - based blood , which appeared thick and black when exposed . They possessed a unique blood filtration and cleansing system which processed through two livers . Because their bodies were constantly cleansed of toxins and carcinogens , the species was highly resistant to poison . To this end , sulfur was used as a stimulant on Devaron to enhance speed and strength , because inhaling it caused the substance to enter the bloodstream rapidly . Their livers struggled to eliminate sulfur from their system , meaning that long - term use could be dangerous . The Devaronians were one of the more unusual races in the galaxy , with a dramatic in appearance and temperament . The males were aggressive by nature , many being described as brash or bull - headed , with typically red - tinted skin and a pair of large horns growing from their heads . They took great pride in their horns , and groomed them quite regularly . Many species felt uncomfortable in their presence , for they resembled the devils of a thousand different myths . Female Devaronians were covered in thick fur that ranged in color from brown to white , hornless and had prominent canine teeth . They were docile , non - aggressive creatures . They tended to be dominant in their culture , being the only ones allowed to participate in government and politics . Several female Devaronians not covered with thick fur revealed two dark circles above the forehead , where the horns usually are in males . In addition , the teeth of the males were all sharp incisors , but the females also had molars and prominent canines . One in fifty Devaronian males had two sets of teeth , however , having an inner set of sharp " male " teeth and an outer , retractable set of " female " teeth . In primitive times , such males were used as solitary scouts by Devaronian tribes , since they could survive on either meat or plants . Males also had an extremely long tongue , though whether females shared this trait is unknown . The teeth were useful for some languages . A Devaronian had to continually and repeatedly retract and extend both sets of teeth to speak Huttese , causing aches over time . Society and culture . First devising the tumble hyperdrive around 27 , 000 BBY , Devaronians were one of the first species in the galaxy to develop interstellar travel . The males of the species had been common sights in spaceports throughout the galaxy for thousands of years by the time of the Galactic Civil War . Devaronian males were driven by an urge to wander , usually taking the first opportunity to move on from one place to another . As such , they were often found traveling the galaxy as tramp freighter captains and scouts . Female Devaronians , on the other hand , were content to remain in a single location , and , as such , raised the young and ran the government of Devaron . The males sent as much money as they could manage back to their homeworld to support their families , but otherwise hardly ever returned once they had begun to travel the stars . The females were content with this arrangement , as they tended to view the restless males as disruptive to home life . Mating rituals consisted of the season of Koh ' hibril . Females were dominant therefore , as that was the only time couples spend long periods together . " Oshmahr " was a mid - day meal ceremony of the Devaronians . Force - sensitivity was found in higher frequencies among Devaronians then in other species . Despite this , no strong Force - based tradition emerged on Devaron or among their colonies . The Jedi Order established the Eedit Temple on Devaron to train the Forceful children there , with females making up the larger percentage of students as males desired to travel more than the Jedi culture permitted . Devaronians in the galaxy . Sometime during the rise of the Empire , one Kardue ' sai ' Malloc , a captain in the Devaronian Army , received the order to put down a rebellion against the Empire on Devaron . The rebels were taking refuge in the ancient city of Montellian Serat . He shelled the city until the rebels surrendered , then finished it , turning the city to rubble . When he received more orders to move south to another group of rebels , interpreting them as ordering mass executions , he herded the seven hundred rebels into a holding pen , then had the guards open fire . He assumed the name Labria and went into hiding after his fellow Devaronians placed one of the galaxy ' s highest bounties on his head for his deadly wartime activities . He was seen in the Mos Eisley Cantina when Obi - Wan Kenobi and Luke Skywalker came looking for passage offworld . Nevertheless , very few Devaronians joined the Alliance to Restore the Republic during the Galactic Civil War . The infamous Devaronian , Vilmarh Grahrk , was a con artist and smuggler active during the latter days of the Galactic Republic . Kapp Dendo , served with the Alliance to Restore the Republic and eventually became a general in the New Republic military . Behind the scenes . The first appearance of Devaronians was in " " ( in the background of the Mos Eisley Cantina ) and only appeared there because the costume department ran out of alien costumes for the extras and used a second - hand " devil " costume .
