Adar Adars were pack - hunting reptilian creatures with sail - like wings , which hailed from the blistering hot planet of Omiddelon III . Cunning and dangerous hunters , adars were found on numerous worlds and space stations in the galaxy , where their adaptive metabolisms allowed them to survive on virtually any food source . Biology and appearance . A typical adar was a reptilian creature with a long , spiky tail and large , membranous wings on its back . Its huge , clawed forelimbs were used for scampering through obstructed areas , while it used its hooked rearlimbs to propel itself through the air by taking great leaps . Gliding on air currents , the adar used its tail for balance when in motion . The adars were well adapted to their environment , particularly when food was scarce as they stored excess water and energy in their tails , and evolved to metabolize virtually any food source . Adars could eat anything from the protein s of living beings to plants and even wood , rock , and minerals . However , the adaptive process could take months to complete , and those who adapted to non - standard food sources had a greatly reduced life span . Their long bodies required an intense amount of energy during their active seasons , and their high metabolisms required the adar to eat their body weight in food every day to match their energy output . Those adars who drew on stored energy risked releasing an enzyme during the conversion process that eventually induced a trace - like state in which the adar slowed its breathing and energy use , becoming motionless until it was able to detect a nearby food source . Some adars who entered this state could survive for up to eight months , particularly in sheltered areas . Their adaptive metabolisms allowed adars to live in forests , jungles , and swamps , as well as urban and rural areas , so long as food was available . Adars were pack animals , with hunting parties ranging in size anywhere from four to over three dozen adars . Their battle tactics made them cunning and dangerous predators , even to Humans and large grazing animals : Adars would separate , flying on their wings to cover large areas , and upon locating a food source , a single adar could let out a piercing scream to attract its pack . Surrounding their prey , the adars leaped at or " dive - bombed " their targets , often simultaneously , to devastating effect . History . The adars native to the planet Omiddelon III were forced to continually adjust to their habitat , which was primarily governed by intense light , heat , and radiation . Further , the world ' s poles were oriented parallel to the orbital plane , meaning that planetary regions suffered periods of blistering heat and freezing cold with only brief mild seasons in between . While Omidedelon proved hostile to Humans and saw many life - forms die out , the adar population survived despite the formidable challenges of their environment . Like other native life - forms , the adar were active in the milder seasons and hibernated during the extreme weather . Because of this , the species became the dominant predators on Omiddelon III , and on other planets of the galaxy as well ; adars were accidentally transplanted to other worlds , and were reported anywhere from urban waste systems to isolated farms and even space stations .
