C-21 Highsinger was a droid bounty hunter that operated during the Clone Wars. He was part of a syndicate of bounty hunters that included Boba Fett, Latts Razzi, Dengar, Bossk, and Oked. He had extensive modifications, including precision-engineered servomotors and manipulators. Although a deadly combat droid, C-21 Highsinger had his battle programming pushed beyond its limits when defending Otua Blank's subtram from the swift Kage Warriors.
Mission to SerennoEdit
In the second year of the Clone Wars, Highsinger and several other members of Boba Fett's syndicate including Latts Razzi, Embo, and Fett himself were frequenting a bar in Coruscant's Level 1313 when they were visited by the undercover Jedi Master Quinlan Vos. Vos had been dispatched by the Jedi Council on a mission to assassinate the Separatist leader Count Dooku and had been partnered up with Asajj Ventress, a Dathomirian Nightsister who had once been Dooku's Sith apprentice. Fett informed Vos that Ventress was hunting a Volpai fugitive named Moregi on Pantora. Vos traveled to Pantora where he managed to partner up as a bounty hunter before revealing his true identity and enlisting Ventress' support to kill Dooku.
Following the failure of Vos and Ventress' assassination attempt, Highsinger and his fellow syndicate members took part in a mission to infiltrate Serenno and rescue Vos. Earlier, Fett had been visited at the Mos Eisley Cantina on Tatooine by Ventress, who wanted to rescue her partner and lover from Dooku. Highsinger accompanied his fellow syndicate members and Ventress as they traveled on Fett's starship Slave I to Serenno. While Ventress infiltrated Dooku's prison, Highsinger and his associates staged a diversion and attack several Separatist vehicles and droids. They even managed to snare Dooku under some webbing but were forced to flee when Vos spurned Ventress' rescue and openly sided with Dooku.
