Dalek Supreme (Desperate Measures)

Months into the Last Great Time War, a Dalek Supreme led the Daleks' assault on Project Revenant's pocket dimension, intending to use the facility to produce Daleks and to exploit its link to the Death Zone to reach Gallifrey. It was killed when the pocket dimension collapsed. Afterwards the Emperor ordered the Time Strategist to appoint a new Supreme. (AUDIO: Desperate Measures)
