"I've got business with the Senate. How 'bout you fellas step aside?"
- ―The Senate Guard Captain and Cad Bane
The Senate Guard Captain served in the elite division of the Senate Guard during the final years of the Galactic Republic. By the time of the Clone Wars, he was part of the security detail in the Senate Office Building—the headquarters of the Galactic Senate, located on the capital planet of Coruscant. Following the arrest of the Hutt crime lord Ziro, Cad Bane led a team of bounty hunters to the Senate headquarters where they encountered the officer and a group of commandos on a restricted landing platform. Before they could arrest the Duros for trespassing, Aurra Sing used a sniper rifle to kill several guards from a distance. Taken by surprise, the captain was also killed when Bane snapped his neck. After securing the platform, Bane's BX-series droid commandos used the deceased soldiers' armor to disguise themselves as Senate Commandos while the rest of the team infiltrated the building and took a group of senators hostage in order to pressure Supreme Chancellor Sheev Palpatine into releasing Ziro from the Republic Judiciary Central Detention Center.
