The Dalek Drone was a Dalek variant introduced in Doctor Who during the Eleventh Doctor's run. As part of the New Dalek Paradigm, it sported a bulkier mechanical shell than standard Daleks. Its livery was red and it sported grey domes over its "skirt". It also featured the standard Dalek manipulator arm and blaster.
As its name would suggest, Drones were to act as the basic labourers and soldiers of the resurrected Dalek Empire. They would have been the most common type of Dalek anyone would see, whether on the battlefield or aboard Dalek ships, within bases or any occupied territory. However, following the establishment of the Dalek Parliament, the bronze-shelled Daleks of the previous empire were reintroduced and would fulfill the role of the Drones. The Drones would then be promoted to an officer class that directed the bronzen Daleks.
At the climax of the Siege of Trenzalore, the New Dalek Paradigm was completely wiped out after the Eleventh Doctor used his newly-granted regeneration energy to wipe out the Dalek assault force. The red Dalek Drones, as well as the other New Paradigm types, were never seen again after this.
