Onca Onca was a male Ithorian bounty hunter who was in operation during the Clone Wars , together with his brother Bulduga . Onca ' s and Bulduga ' s reputation caught the eye of the Sith Lord Count Dooku and Phindian criminal mastermind Moralo Eval , who invited both brothers to participate in a series of challenges at the Box on the planet Serenno . As Bulduga was killed before they arrived at Sereno , Onca was forced to participate alone . History . At some unspecified point in their lives , Onca and his brother Bulduga became bounty hunter s and formed a legendary duo throughout their careers , becoming famous across the galaxy . In 20 BBY , during the Clone Wars , both brothers were invited along some other fellow bounty hunters by the Sith Lord Count Dooku and the Phindian criminal mastermind Moralo Eval to participate in a series of challenges at the Box on the planet Serenno . The duo ' s reputation was the main reason for which they caught Dooku ' s eye . Unfortunately , Bulduga did not live to take part of the competition because the Duro bounty hunter Cad Bane finished him and fancied his hat and asked how got it . As Bulduga responded by drawing out his pistols recognizing the conversation ' s tension , Bane drew his blaster first and shot fatally Bulduga and taking his hat for his own . Onca witnesses this event , but as he wasn ' t a fool he didn ' t dared to face off against Bane , although he secretely mourned for his deceased brother . Competing against other bounty hunters in the potentially fatal challenges , the victors would receive the honor of kidnapping Supreme Chancellor Sheev Palpatine of the Galactic Republic . Onca did well the first challenge like the others , even although by Embo ' s fault he nearly fell to his death at the Dioxis released at the gas room , and made it to the second challenge . Once there , the bounty hunters discovered that the room was full of electrified laser blade columns just when one nearly impaled Onca ' s head after Rako Hardeen pushed Jakoli to safety , but Onca bent to avoid that fate . In a matter of seconds , however , Onca was cornered by the columns and one got directly to his head , with the laser near to his face threatening to slice it , but as the laser didn ' t got to far , it returned to its origina position . Thinking that he was safe , Onca sighed of relief , but he was quickly impaled in the back by a laser blade before he can became aware , killing him and thus becoming the first bounty hunter to die in the challenges . Personality and traits . Along his brother Bulduga , Onca was part of a successful legendary bounty hunting team famous over the galaxy . In contrast of his brother , who was a fast - drawing gunslinger , Onca was slower , incapable to overcome the bulk of his Ithorian build to snap off shots as quickly as Bulduga could . This last trait would eventually cost to Onca not only his career , his life also , when he was fatally cornered at the Box on Serenno . Equipment . Onca favoured firepower over finesse or flash . Onca frequently carried more than one blaster rifle , including a sawed - off one , at a time . Behind the scenes . Onca appeared first and only physical appearance was in the episode " The Box " of the TV show " " . He later apppeared in a flashback sequence of the episode " Crisis on Naboo " .
