Aga, originating from the world of Zelos II, were sizable, six-legged entities of semi-sentient nature. These creatures existed in packs and were inclined to assault other beings, motivated by both sustenance and the thrill of combat. Their utilization of rudimentary implements, like clubs, hinted at a capacity for greater development. Notably, during the era of the Galactic Civil War, the Emperor Palpatine is documented to have employed them as sentinels, achieved through the use of narcotics.
