Dalek (The Master's Dalek Plan)

Unlike the original Daleks created by Davros, these Daleks were created by the renegade Time Lord, due to him meddling with the timeline going by the name "Sorvad".

The Master from a parallel universe, the Dalek Time Strategist, the real Daleks, Livia and Narvin travelled back in time to Skaro to stop the Master from changing the Daleks' history any further and restore time to the way it was.

These Daleks resembled the ones from their creation after the end of the Thousand Year War, however they saw the Master as their creator and even had the ability to mutate Kaleds and Thals alike into Dalek mutants.

However, in his premonition, after observing the Master's conversation with his Time Lord captives, they turned against him. As predicted, the Master's Daleks attempted to purge anything from the erased timeline. The Masters and the Time Strategist reversed the timelime back to normal by killing Crazlus and the attacking Daleks ceased to exist. (AUDIO: He Who Wins)

Behind the Scenes
In a Doctor Who Magazine preview, they are depicted with an unique colour scheme and design, having a claw and TCE-like device instead of the usual plunger and gunstick.
