Hagark, a male Felucian from the Legends continuity, existed in the initial period of the Galactic Empire's reign.
Hagark's home was the planet of Felucia. However, the Imperial Captain named Vischera seized him and imprisoned him in an Imperial prison. Vischera tampered with Hagark's DNA, resulting in the Felucian's increased size, heightened aggression, and complete loyalty to the Captain. Hagark, along with Kargrek, another Felucian modified in a similar fashion, underwent combat instruction under Vischera's supervision, ultimately becoming his personal protectors. Hagark and Kargrek were with Vischera during his assault on a team of Alderaanian Resistance operatives who had secretly entered the prison.
