Yaga ( species ) The Yagai ( singular , Yaga ) were sentient insectoids indigenous to Yaga Minor . They were one of the many species enslaved and exploited by the Galactic Empire . Biology and appearance . The Yagai were an insectoid species . They stood on three strong legs arranged in a tripod pattern , with their rear leg facing backward . They had two arms , with each arm ending in a hand with nine opposable digits . The Yagai were usually tall and thin , with a long torso , skinny fingers , and a long thin neck . Their multiple digits were well - suited for fine mechanical and technical work . After their subjugation by the Galactic Empire , a subspecies of Yaga drone s were created through genetic engineering . These drones were even larger than the usual Yaga , and very muscular . The drones possessed thick bulky armor , and moved slowly . They were created to survive in deep space , where the Yagai could not go . They were very dim - witted , and rarely spoke except to acknowledge commands . Once a drone was fully grown , it only required solar energy to survive . Society and culture . Yagai culture was primarily centered around technical and mechanical prowess and achievements . They were specifically talented in the area of hyperdrive technology . Elder Yagai fully encouraged younger generations to take up professions in technical fields , fearful of the repercussions if the Imperials decided the Yagai were no longer useful . They were an aggressive and territorial species , but rational enough to submit to the Empire ' s might . Some believed they would make a valuable asset to the Alliance to Restore the Republic . The Yagai were fully aware of the atrocities the Empire committed the galaxy over , and had no desire to meet a similar fate . As such , though they deeply resented being controlled — and twisted into the Yagai drones — they did little more than seek opportunities for sabotage . With the entire population of Yaga Minor effectively held hostage , the Yagai fully submitted to Imperial rule . Some Imperials , like High General Hestiv , mistook this submission for loyalty to the Empire . The Yagai favored baggy , flowing garments such as jumpsuits . Their clothing was usually white or a shade of blue or purple , which were neutral colors on their homeworld . They are known to favor a spicy dish called Dindra . As a result of the enslavement of their species and the blockade of their system , free Yagai were rarely seen in the galaxy . Those away from their homeworld were either escaped slaves , who feared being recaptured , or slaves forced to work for Imperial masters in distant part of the galaxy . Yagai drones were indoctrinated from birth to unquestioningly follow the orders of their Imperial masters . Most Yagai considered the drones to be non - citizens . History . During the time of the Galactic Republic , the Yagai were renowned for their starship engineering skills and their cooperation with the galactic community . After the rise of the Empire , however , they were quickly subjugated and enslaved . The Empire built a major Imperial shipyard above Yaga Minor and shipped Yagai technicians across the galaxy to help maintain the vast Imperial Fleet . At the time of the Imperial Remnant , slavery was banned and the relationships between Yagai and the Empire were significantly improved , a result of Admiral Pellaeon ' s tolerant politics .
