He primarily worked with his brother , Bulduga , in their legendary bounty hunting team . Onca and his brother traveled to Serenno to take part in a contest within The Box , though Bulduga never took part in the competition because he was killed by bounty hunter Cad Bane . Onca also perished , but in the second challenge from an electrified laser blade . Biography . Onca and his brother formed a legendary duo throughout their bounty hunting careers . Eventually , their many successes caught the attention of Count Dooku , who invited them to compete with several other bounty hunters in The Box , a death machine that tested the skill and mind of each person who entered it ' s deadly grasp . The Box was designed by Moralo Eval , a Phindian mastermind who was behind the plot to capture Supreme Chancellor Palpatine . The contest was held on Serenno , Count Dooku ' s homeworld . The five contestants that survived The Box , would win the honor of kidnapping Chancellor Palpatine to use as leverage to free all captured Separatist leaders from the Republic . Unfortunately , Bulduga did not live to take part in the competition . Another participant , Cad Bane , fancied Bulduga ' s hat and asked how got it . Bulduga , recognizing the tension of the conversation , responded by drawing out his pistols . He wasn ' t fast enough . Bane drew his blaster first , shot Buldaga and took his hat while Onca looked on . Onca was not a fool and did not face off against Cad Bane , though he did secretly mourn for his brother . All contestant were required to give up their weapons before entering The Box . The contestants were herded onto an elevator and escorted by magnaguards into a pristine white chamber that sported square paneling on all sides . As the contestants regarded their surroundings , a panel in the middle of the floor sank , creating a small shaft which released dioxis gas into the room . Onca and the other bounty hunters retreated from the gas , heading toward the outer edges of the chamber . As the gas progressed it ' s way into the room , several panels began to slowly ascend from the floor , providing platforms for the competitors to perch on above the gas . Despite his sluggish maneuverability , Onca managed to obtain a foothold on one of the rising platforms . Though , as the platforms continued to rise , it became clear that the exit was not up but down . Rako Hardeen , secretly Obi - Wan Kenobi , scouted out the floor of the chamber and discovered that the shaft that released gas into the room had a secret tunnel at it ' s bottom . Onca was the last to drop down into the gas to follow Hardeen and survived the first challenge . The room they entered into from the tunnel was very dark and cubical in shape . A panel , tipped with an electrified laser blade , slid forward across the room and would have impaled Onca if he had not dodged it . Several more panels , also tipped with the same deadly weapon as the first , slid across the room . Onca became suddenly boxed in by several panels and was forced to stand perfectly still as a panel slid towards him . The blade stopped inches short from slicing into Onca ' s head , much to Onca ' s relief . Though Onca was caught off guard and impaled through the back by an electrified laser blade that sprouted out of the panel behind him . The five contestants that escaped The Box in the end were Derrown , Twazzi , Cad Bane , Rako Hardeen and Embo . They went on to kidnap the Chancellor at the Festival of Light on Naboo .
