This company , controlled by Archduke Poggle the Lesser , was responsible for producing thousands of battle droids . At the wishes of the Trade Federation , one of the company ' s main customers , Dellso helped design a signal override to shut down the company ' s droid army that could be used in case enemies ever attempted to use their droids against the Trade Federation . Following the formation of the Confederacy of Independent Systems in 24 BBY , Dellso , like all his people , joined the movement . In 22 BBY , the Clone Wars broke out . Dellso continued to fight against the Galactic Republic until the war ended in 19 BBY and the Confederacy ' s battle droids were shut down by the signal Dellso had designed . Following the war ' s end and the Confederacy ' s dissolution , Dellso traveled to the Confederacy ' s secret bunker on the Outer Rim planet of Mustafar , determined to continue the fight . He had with him a set of experimental plans for a prototype starfighter that he had managed to steal from the Galactic Empire , the government that had replaced the Republic . On Mustafar , Dellso was able to not only locate an abandoned droid production factory , but to restart it as well , producing a number of battle droids and starships . He also designed a Confederate infantry prototype , which he planned to put into action for his rebellion . In creating a new droid army , Dellso became the leader of one of the last Separatist holdouts . Sometime between 18 and 12 BBY , the Empire became aware of the threat that Dellso posed . Seeking to end the rebellion before it could develop into a full - fledged war , Emperor Palpatine dispatched the elite 501st Legion to eliminate Dellso and destroy his droid army . The 501st was confronted in space by Dellso ' s fleet . However , the legion was able to destroy a number of droid starfighters , cripple Dellso ' s flagship , a " Providence " - class carrier / destroyer , and steal a Belbullab - 24 strike bomber . The legion then landed on the planet . Though Dellso ' s army fought to repel the stormtroopers and keep his rebellion alive , they were unable to do so . Determined to prevent the Clone Wars from occurring again , the Empire ' s forces defeated those of Dellso and destroyed the prototype battle droid schematics . Dellso realized that the battle was lost to him and , accompanied by his bodyguards , attempted to flee . As the Imperials fought with the remains of his droid army , Dellso entered the fray armed with a Bulldog RLR and rained heavy fire down upon the Imperial forces , who were taken by surprise and suffered many losses as a result . However , the Imperials quickly recovered and rallied and though Dellso and his remaining entourage fought fiercely , they were ultimately overwhelmed and killed by the 501st . The Empire then bombarded Mustafar from space , destroying the factory and the last remnants of Dellso ' s army . Personality and traits .
