- "These Geonosians have been working on a new Confederate infantry prototype. Destroy the schematics before they can use it to build a new droid army."
- ―An Imperial officer of the 501st Legion
Gizor Dellso's droid prototype schematics were the plans for a battle droid concept that never came into fruition. The droid resembled a B-series battle droid, with a similar torso to the B2 super battle droid; but with a much larger and box-shaped head.
Originally intended to be used by the Confederacy of Independent Systems, Gizor Dellso, a Geonosian engineer, reactivated a previously hidden factory on Mustafar and around 12 BBY, created his own private droid army. This resulted in the Empire's swift military action. Prior to the battle, he found old schematics for the droid and proceeded to start mass-production. Before production had finished, the stormtroopers of the 501st Legion destroyed the schematics, ending any hope of activating them.
