Dargo was a settler of planet Brunk who was sent to Grumborg Prison for devouring one of his business partners. He enjoyed tormenting and devouring new arrivals, until Morbilus Grendy showed up and, with charisma and confidence shocking in a man his age, put Dargo in his place. He later intended to eat Spuckler Boach and was getting his butt kicked by the latter when Grendy intervened.
