Gizor Delso was a Geonosian worker and the head technician of the Confederacy of Independent Systems, for whom he had helped design and construct a signal override device for the Separatist Droid Army, easing the Trade Federation's fears that the droids might be used against them.
Living his whole early life on Geonosis, Gizor Delso never quite made it to as high a rank as his rival, Sun Fac. Delso served as an engineer in the Stalgasin Hive and assisted in the activation procedures of the Separatist Droid Army in the secret factory on Geonosis. He was responsible for the army's last-minute preparations when the Battle of Geonosis broke out and ignited the Clone Wars.
During the final days of the Clone Wars, Gizor Delso finally departed from his homeworld to go to Mustafar, the final location of the Separatist Council. At that time, his employer, the Geonosian ruler Poggle the Lesser, and the other Separatist leaders had already been attacked and killed by Darth Vader, the notorious agent of the newly-formed Galactic Empire. After their deaths, the Clone Wars had supposedly been brought to an end. However, Delso was intent on keeping the war alive.
The battle droid deactivation signal was transmitted across the galaxy by Darth Vader, and Delso arrived on Mustafar only a few days after the massacre to find the Separatist Council members dead. He also discovered the Separatist's abandoned droid factory and immediately dreamed up a plan that he hoped would continue the Clone Wars. Delso's reasoning was never clear, but he soon became the self-declared leader of his Confederate Remnant.
The Mustafar Confederate RemnantEdit

Stealing plans for an experimental Imperial starfighter and entitling himself the "final commander" of the Confederacy of Independent Systems, the Geonosian holed up on Mustafar, along with his Geonosian bodyguards. He raised a "hibernating" battle droid army with amazing speed, and sent up many CIS ships, originally left to defend the Separatist Council on Mustafar, in order to create his own fleet.
Although the Confederate Remnant on Mustafar initially seemed to be little threat to the Empire, Darth Vader finally decided to take action. He sent the 501st Legion to Mustafar to assassinate Delso and crush his surprisingly well-strategized uprising. The 501st stormtroopers were baffled to find Delso had a Providence-class carrier/destroyer protecting the planet. Immediately, the Battle of Mustafar commenced, where the 501st eventually broke through Delso's fleet, raided the bunker, and destroyed his plan for a new, superior battle droid, and ultimately a new droid army. Delso, seeing his plot foiled, hid himself away in his volcanic stronghold. When the Imperial troops raided the complex control room, the power-hungry Geonosian was nowhere to be found. Engineers who were inside the room and communicated with him inside his bunker were gunned down.
Upon losing contact with his accomplices, Delso knew of his revolt's imminent failure. Not wanting to be trapped in his stronghold while the Empire prepared an orbital strike on the planet, Delso made a bold attempt to escape the battle area alive. Flanked by heavily-armed Geonosian bodyguards, Delso tried to break Imperial ranks, taking many lives with a Bulldog RLR. However, he was impossibly outnumbered, soon saw his uncoordinated associates fall around him, and was thus left exposed to crossfire. He made one final leap to escape with his life, but fate wouldn't let it happen, as Gizor was gunned down by one of the 501st stormtroopers. After his demise, his entire droid facility was destroyed by orbital bombardment and Mustafar was reclaimed by the Empire. With Delso slain, the last real influence of the CIS was finally destroyed.
