Boushh was an Ubese male from Uba IV who joined the bounty hunting profession early in his life, proving a keen combatant and expert hunter. Although he was slight of build, Boushh wore a suit of "armor," which consisted of layers upon layers of brown survival clothing, and an optically-enhanced helmet; this helped mold his reputation as a formidable and dangerous hunter.He acquired a horde of facial scars from his adventures,though because he hardly ever took off his mask in public, few ever saw them.

Boushh trusted no one, and often kept tabs on his employers, looking for information he could use against them should they attempt to betray him. He made few alliances during his time as a bounty hunter; he roamed the Outer Rim Territories, working for various different employers, rarely staying with one for more than a few months. He did, however, work alongside several other hunters on occasion, such as the Wookiee Snoova, and Beylyssa, a Human female. Beylyssa and Boushh both shared a love of explosives, but their partnership ended violently—neither of them was badly injured, though. Rumors abounded that Boushh sent much of his profits on to other struggling Ubese bounty hunters. It was surmised by many of his fellow bounty hunters that he was part of a network of elite Ubese mercenary units. However, these rumors were never proved and their accuracy was doubted by many.

Boushh also worked as part of Crimson Nova—a subset of Bounty Hunters' Guild dedicated to hunting down Jedi survivors of Order 66—for a time, and hunted Jedi Knight Kai Justiss on Garqi alongside fellow hunters Zuckuss and Breela at some point. Boushh's work with the group was limited, though, and he refused to properly join the Guild.
