In one palimpsest reality which the personal timelines of the Doctor and the Dalek race passed through following the Last Great Time War, (PROSE: The Time Traveller's Almanac) the Ninth Doctor encountered what he believed to be the last surviving Dalek in existence in captivity in Henry van Statten's vault in 2012, (TV: Dalek) in what became known as the Van Statten Incident. (PROSE: Dalek Combat Training Manual) Named "the Metaltron" by van Statten, this Dalek was unfamiliar to its human captors. (TV: Dalek)
At the time of the incident, the Doctor believed that both the Time Lords bar himself and the Daleks had been wiped out at the end of the Time War, to the point that he initially took the sight of the lone Dalek on Earth in 2012 to be "impossible". This lone Dalek survivor, who was skeptical as to the Doctor's account of the war's end, searched for traces of its kind by scanning Earth's internet, satellites and radio telescopes, only to find "nothing". (TV: Dalek)
In his next incarnation, the Doctor was in Torchwood London in 2007 when the Cult of Skaro emerged from the Sphere within the Void and precipitated the Battle of Canary Wharf (TV: Army of Ghosts/Doomsday) before going back in time and influencing the construction of the Empire State Building for their own ends, (TV: Daleks in Manhattan/Evolution of the Daleks) also being indirectly responsible for the Earth being transported to the Medusa Cascade. (TV: The Stolen Earth/Journey's End) In the earlier "Metaltron" reality, however, the personal timelines of both the Doctor and the Daleks' had not progressed to the point where those events occurred. This meant that, at the time of the Van Statten Incident, the Cult of Skaro was still inside their Sphere within the Void. (PROSE: The Time Traveller's Almanac)
