The Power of the Daleks is the completely missing third serial of the fourth season of British science fiction television series Doctor Who, and which was first broadcast in six weekly parts from 5 November to 10 December 1966. It is the first full story to feature Patrick Troughton as the Second Doctor. In this serial, the new Doctor (Troughton) and his travelling companions Polly (Anneke Wills) and Ben (Michael Craze) land on the planet Vulcan. There they find an Earth colony, where the lead scientist Lesterson (Robert James) discovers a 200-year-old alien capsule containing three inactive Daleks. Once brought back to life, the Daleks act as the colony's servants, but all they really want is power. Although audio recordings, still photographs, and clips of the story exist, no episodes of this serial are known to have survived. This is the sixth incomplete Doctor Who serial released with full-length animated reconstructions of its six missing episodes. All six episodes were released on the BBC Store from 5 November–10 December 2016 in weekly order, 50 years after the serial's original broadcast dates. Plot After his transformation from an elderly man into a younger man, the Doctor seemingly ignores or deliberately misunderstands direct questions from his companions Ben and Polly, and refers to his previous self as another person. His companions are at first unsure how to treat him: Ben suspects he is an imposter, but Polly is willing to believe he is the same man. The TARDIS lands on the planet Vulcan, where the Doctor witnesses the murder of an examiner from Earth, sent to inspect the planet's colony (why the examiner was summoned is a mystery). The Doctor, using the dead man's badge, pretends to be the examiner. A security team, led by Bragen, escorts the Doctor, Ben and Polly to the colony, where they meet the governor, Hensell, and his deputy Quinn. There are indications of a rebel faction that Hensell does not take seriously. The Doctor and his companions learn of a two-century-old capsule discovered by the colony's scientist, Lesterson. The Doctor sneaks into the laboratory, with Ben and Polly following, where they discover two Daleks inside the capsule, with a third missing. The group is discovered by Lesterson; the Doctor asks him where the third Dalek is, and the scientist reports that he hid what he assumed was a machine, with the intention to reactivate it. Later,
