Yoogish, commonly known as yoogs, were primate humanoids with elongated faces that drooped roughly a quarter of their height. Their primitive nature allowed for them to band together in large numbers, overwhelming their competition for food, shelter, or anything else that was important to their survival. They were sentient enough to work in menial labor but some that developed higher intelligence became scavengers and pirates. They largely inhabited the planet of Cytos, a tropical jungle covered world bombarded by heavy radiation from its sun Cyno.
