1972 Grey Dalek Warriors
These dark grey Daleks appeared several times. They first appeared in Day of the Daleks under the command of a gold coloured Dalek. Day of the Daleks was the first TV story to feature the Daleks in colour.
Newly painted Daleks appeared in Genesis of the Daleks under the command of Davros. Later in Destiny of the Daleks one of these Daleks had survived and appeared to be in command of some lighter grey Daleks.
