Gizor Delso

Gizor Delso was a Geonosian fugitive who rebelled against the Galactic Empire shortly after the Confederacy of Independent Systems was defeated. He and his Geonosian bodyguards landed on Mustafaar and raised a "hibernating" Battle Droid army. Among Delso's new soldiers were Magnaguards, Droidekas, Battle droids, Sith Probe Droids, and Super Battle Droids. In the case of an invasion, he would utilize the stronghold's turrets, which were automated. He then sent up many CIS ships to create his own fleet, in which there were many Droid Starfighters, Droid Tri-fighters, and other ships.

Darth Vader decided to take action. He sent the 501st Stormtrooper Legion to Mustafaar after they put down a rebellion on Naboo. The Stormtroopers, upon arrival, were attacked by droids, who boarded their ship. The hangers were not ready for attack, and thus were filled with crates of supplies and fuel. The droids and soldiers used these as cover. Then, the stormtroopers pushed the automatons back. The pilots used TIE fighters, TIE Interceptors, and TIE Bombers to push back the droid fleet. The Imperial Pilots destroyed many fighters, and destroyed an auxillary Banking Clan Ship, killing many droids and alien crew. Soon, a pilot was order by an Imperial Officer to fly into the hangers of a Seperatist ship, steal a Seperatist bomber, and return the bomber to the Star Destroyer's hanger for study. Finally, after this was completed, the soldiers destroyed the ship and took the fight to the surface.

After many heated battles, the droids were pushed back. Many stormtroopers and officers were killed fighting, too. A group of soldiers invaded the control room and destroyed the schematics for the droid army. Then, a commando was ordered to steal a Seperatist data disk. After this was accomplished, Gizor Delso himself came out to fight. A large amount of Geonosians came as well, to help their leader. Many stormtroopers were killed by the droids, the Geonosians, and Delso himself, but soon he was killed. After their leader's demise, the rest of the robots and Geonosians were killed quickly.
