Major Rigosso was a Belugan male military officer in the service of Lord Otua Blank on the planet Quarzite. During the year 20 BBY, the Belugans kidnapped the Kage female Pluma Sodi with orders to bring her back to Blank for the dictator's personal pleasure. However, as the threat of Sodi's rescue by Kage Warriors loomed over the mission, Rigosso hired a team of six bounty hunters to protect and safely deliver Sodi to Blank's stronghold.
