Haden Vazzar, a Human male, was a member of the Galactic Republic during the era of the Jedi Civil War.
Vazzar held the lieutenant rank and functioned as a scout within the Republic's forces. In the year 3957 BBY, Vazzar participated in a Republic operation to the planet of Sernpidal, where he and his team successfully retrieved a code cylinder. This cylinder contained the necessary command codes for the sensor arrays located on Darth Revan's flagship. Subsequently, they journeyed to the Republic vessel, the Viscount, and aided the Jedi Bastila Shan in their endeavor to capture the Dark Lord of the Sith, Darth Revan. While on this mission, Vazzar and his fellow operatives faced off against Darth Voren, the Sith apprentice.
