Yaga drone

The Yaga drone was a subspecies of the Yaga, created through genetic engineering following the rise of the Galactic Empire.

Biology and appearance

They were larger and more muscular than the Yaga. They were designed to work in deep space and other hostile environments. Upon reaching adulthood, they no longer required any sustenance, surviving only on solar energy. They rarely spoke, usually just to acknowledge orders. While they were trained to be loyal to the Empire, many secretly harbored sympathy to the Rebel Alliance.
