Sun Fac was the Geonosian Advisor to Poggle the Lesser in the years before the Clone Wars. He formed the Advanced Droid Division after Geonosis pledged itself to the Confederacy of Independent Systems and was present as Poggle's aid during the formation of the Confederacy inside one of Sun Fac's droid factories. When the Battle of Geonosis broke out, Sun Fac activated his B1 Advanced Battle Droid Units and had them protect the area around his place. He prepared to escape the planet while his droids held off Clone Troopers outside his palace, but was killed when a Republic Commando group called Delta Squad broke into his hanger bay and sniped down his Geonosian Starfighter.
