Frist was a person who held the rank of captain within the Galactic Republic's navy during the Clone Wars conflict. As the war progressed, Frist took on the role of flotilla commander for the fleet garrisoned above Geonosis. His primary duty was to safeguard the highly confidential construction project underway there from assaults by the Separatist forces. When the Geonosian drones initiated a rebellion to liberate their leader, Archduke Poggle the Lesser, Frist received instructions to pursue the Archduke's personal ship as it departed the planet's orbit. Despite Lieutenant Commander Orson Krennic's command to engage the escaping vessel, it arrived too late for Frist to prevent Poggle's successful escape.
