Zap'Ulga, a male Dug from legends, worked for Sebolto and participated in both pirate operations and the illegal hunting of Nexu. Senator Ask Aak sought him for his suspected involvement in a series of attacks on Republic freighters transporting aid to Malastare.
The infamous bounty hunter Jango Fett eventually collected the reward for Zap'Ulga, valued at 4,000 credits if captured alive and 2,000 credits if deceased, while trying to reach Sebolto.
