"Imperial scum!"- Dellso, to a Stormtrooper
Gizor Dellso was an Geonosian Inventor who worked for the Confederacy of Independent Systems during the Clone Wars and a rivle of Sun Fac. During the war, Gizor created an automated shut down of the entire Confederate Droid Army, after a group of geonosians, including himself, thought that their army may try to rebel against them. After the Birth of the Galactic Empire the Sith Lord, Darth Vader stole Dellso's deactivation device to destroy the entire Droid Army from Mustafar. Dellso, upon discovering this, returned to Mustafar and seized control over an abandoned droid factory on the planet and used it to create his own personal army along with a massive fleet of starships. In the year 13 BBY, Dellso used his army to attack Coroscant. This attack failed, and the Empire was able to defeat the droid forces and tracked them back to Mustafar. The Imperial Forces, however, could not break through the blockade at first until fighter pilots from the 501st Legion crippled the Capital Ship and sent a group of Imperial Stormtroopers to the planet. After destroying prototype B4 Battle Droid blueprints and part of the main droid factory, Gizor Dellso and members of his Geonosian Guard attempted to escape but were forced to attack an group of 501st Stormtroopers. Although they killed many stormtroopers, Dellso and his Guardsmen were all defeated and their outpost on Mustafar was destroyed via Star Destroyer.
