A new "Doctor Who" series was announced for 2005 and the Daleks have appeared in every series since (as of series 11). In the first series of the revival, the Daleks serve as the main antagonists. In "Dalek" (2005), it was revealed that the Daleks were involved with the Time Lords in a Time War, in which both sides were believed to have been practically wiped out. The Ninth Doctor encounters a surviving Dalek who somehow fell through time to 20th century Earth. By 2012, it had passed into the hands of American billionaire Henry van Statten, who dubs it a "Metaltron" and keeps it in a secret underground museum called the Vault along with other alien artefacts. The Dalek is damaged, remaining silent and helpless until the Ninth Doctor arrives at the Vault. Absorbing DNA from the Doctor's companion Rose Tyler, it regenerates itself and goes on a killing spree. However, having absorbed Rose's DNA, it continues to mutate and finds itself beset with unfamiliar, human feelings. Realising it is now "contaminated", the mutant asks Rose to order it to destroy itself, rather than continue to live in that way. It then disintegrates itself with an energy field created by the spheres along its lower casing.
