This bounty hunter from Nimbanel, alongside his Ranat partner, made an appearance at the spaceport of Lothal approximately five years prior to the Battle of Yavin. While at the Imperial posting agency to get ahold of the personal and military records of Lieutenant Jenkes, the Trandoshan Bossk and his guide Ezra Bridger noticed the Nimbanel and Ranat bounty hunters occupying a pair of computer terminals, both visibly armed with holstered blasters.
Subsequently, the Nimbanel and his Ranat associate tried to capture Bossk, who Jenkes had marked for termination. Despite Bossk's attempts to negotiate, the pair disregarded him, leading to a confrontation. During the ensuing fight, Bossk struck the Nimbanel in the stomach with the muzzle of his mortar gun, then stunned him. Following this, Bossk took the Nimbanel's helmet and fled with Ezra to Monad Outpost, a mining settlement, where they faced Jenkes.
