Generation 02 - The "Dal" Daleks: Dalek Workers

• Role: Worker caste – used for construction, demolition and other tasks beneath regular drones.
• Casing(s) Used: Construction Drone Casing
• Appearances: None. This rank is a conjecture based on the fact that the early Daleks must have expanded the metal city beyond that which their Dal forefathers managed.

The workers of the Second Generation were actually regular Dal drones, transferred for a work period into a prototype construction casing. The Dal mutant could survive for long enough to be transferred under controlled conditions from one casing to another. As such, the Dalek city encountered by the Doctor on his first visit to Skaro was the result of centuries work, building from the Kaled testing ground, through the beginnings of the city created by the Dals before they were encased in travel machines and finally completed by the encased Dal workers.

The prototype casings looked identical to the finished versions used by First Generation workers, but were reliant on recharging after a relatively short period.
