A wide-eyed Ithorian boy, Byph was a Jedi youngling studying at the Jedi Temple during the time of the Clone Wars. At the height of the galactic conflict, he was selected as a top student to undergo The Gathering, an important Jedi rite of passage that tested students on the frozen world of Ilum. Byph had to overcome his fearful nature and find the Ilum crystal that would become the heart of his lightsaber.
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.
Most beings in the galaxy assume that Ithorians are peaceful keepers of gardens and contemplative philosophy. The ones who have stared down the barrels of the bounty hunting brothers Bulduga and Onca beg to differ -- if not busy begging for their lives. While Onca favored heavier rifles, Bulduga preferred the fast-draw blaster. Some who noticed Bulduga's low slung holster, red-lensed goggles and wide-brimmed hat wondered if perhaps Bulduga was a copy-cat, looking to imitate another well known gunslinger -- but not within earshot of the deadly Ithorian.
