C-21 Highsinger

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.

Safe cargo objective
During the Clone Wars, Highsinger joined a group of bounty hunters put together by Boba Fett in order to undertake a mission on the planet of Quarzite. The hunters were joined by Asajj Ventress&mdash;although they were unaware of her identity&mdash;after she killed one of the members of their team. The group was tasked with guarding a large wooden chest aboard a subtram, which was to be delivered to the Belugan Otua Blank. Though the trip began easily enough, soon the tram was beset by Kage Warriors, who sought the cargo for themselves. One by one, the hunters fell. Though Highsinger was one of the last hunters standing, the Warriors' leader, Krismo Sodi was able to dispatch the droid by linking him with fellow hunter Latts Razzi as she was thrown from the train. Highsinger fell beside Razzi, though both survived. In his absence, Fett too was bested by Sodi, who soon revealed that the cargo was his sister, Pluma Sodi, who was to be forcibly wed to Blank. Ventress, having suffered many changes in her recent past, ended up placing Fett within the chest and delivering him to Blank, collecting both a bounty from the warlord as well as from the Kage Warriors for freeing Pluma. She then shared the first bounty with Highsinger and the others, telling them that Fett would join them soon enough.

Mission to Serenno
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 High 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 Chalmun's 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 palace, 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.

Galactic Civil War
During the Galactic Civil War, Highsinger was among the bounty hunters hired by Darth Vader to return Doctor Aphra to him, after she was captured by the Rebel Alliance on Vrogas Vas.
