Together with his brother Bulduga, Onca was part of a legendary bounty hunting team. While Bulduga fancied himself a fast-drawing gunslinger, Onca was slower, unable to overcome the bulk of his Ithorian build to snap off shots as quickly as his brother could. Instead, Onca favored firepower over flash or finesse. He often carried more than one blaster rifle at a time, including a sawed-off one.
