Thalek (Brotherhood of the Daleks)

Thaleks was a term coined by Charlotte Pollard to describe the Daleks that believed themselves to be other inhabitants of Skaro, the Thals. The Thal Valion was amongst the Thals turned into one of these Daleks. The Thal-Daleks along with a Red Dalek were destroyed when the facility collapsed when Jesic used the word exterminate. They were even heard singing their own version of "The Red Flag" much to the Doctor's bewilderment. (AUDIO: Brotherhood of the Daleks)
