Stone Dalek

The Stone Dalek was one of The Progenitor Daleks.

History
The Stone Dalek appeared in The Big Bang. It was one of the Progenitor Daleks present at the Alliance's sealing of the Doctor in the Pandorica in 102 A.D.. As the Cracks in Time continued to run rampant across the Universe, Dalek history was erased, leaving the stone Dalek as an 'after image' to quote the Doctor. It was activated after The Pandorica opened: It contained atoms from the original universe, from before the cracks started to erase events. Thus, the light from within the Pandorica reactivated it but the stone didn't fall off. Its power wasn't fully restored so it couldn't shoot, but eventually it got it power restored enough to shoot it's weapon. It was one of the first Daleks to shoot the Doctor. It was also the first Dalek to say "Mercy!" Soon after that it was shot by River Song.
