Stone Dalek

The Stone Daleks were a pair of Daleks left as an after-image when Dalek history was temporarily erased by the universe's destruction on 26 June 2010.

Biography
The stone Daleks were two members of the New Dalek Paradigm at the Alliance's sealing of the Eleventh Doctor in the Pandorica in 102. As the cracks in time continued to run rampant across the universe, Dalek history was erased, leaving the stone Daleks as petrified after-images.

The Pandorica held atoms from the original universe, taken before the cracks erased events, which could sustain life. Light from the Pandorica restored one of the Daleks, albeit with limited power. This stone Dalek shot the Doctor, severely wounding the Time Lord without killing him but depleted its energy reserves nonetheless. It was confronted by River Song, who threatened to kill it by shooting its eyestalk with an Alpha Meson gun. Initially, it did not believe that River would destroy it, thinking that as one of the Doctor's companions, she would show mercy. River told it to look her up in its data banks. After doing so, it begged repeatedly for mercy, shaking in terror. Later, when Amy and Rory asked where it was, she stated, "It died."

When the Doctor reset the universe and timeline, the stone Daleks, along with all things that had been erased from history, were restored to their original form and place in space and time. (TV: The Big Bang)

Behind the scenes

 * The reactivated Dalek was the first heard crying, "Mercy". The lone Dalek in Dalek cried for the Ninth Doctor to "have pity."
 * It is unknown which Dalek of those present under Stonehenge the restored Dalek actually was. The lack of a deep voice suggests that it was not the Supreme. However, its voice is similar to those of the red Drone Daleks in City of the Daleks and Nicholas Briggs has stated that the voice used in the Adventure Games is the voice he would use if he ever had to voice the red Daleks on TV. However, the actual prop that was altered for the Stone Dalek was the Strategist model, as confirmed by director Toby Haynes in a Doctor Who Magazine interview.
 * Two more stone Daleks and two stone Cybermen were supposed to have been seen in The Big Bang; however, due to the costume necessities for The Pandorica Opens, the budget did not support it. Most of a stone Cyberman was seen when the Doctor escaped the Pandorica, additionally a stone Auton Roman appeared.


 * When the stone Dalek moved itself and its eyestalk, the same sound as the Russell T Davies era Daleks was heard when they moved.
