The Dalek Book (1964) is notable, although not unique, in portraying a Dalek variant which has a "speaker grille" set centrally on the chest and, occasionally, a stylised numeral on the dome. Neither of these items has ever been incorporated in a Dalek variant shown on-screen. All episodes exist in 16mm telerecordings. The episodes were all recovered from negative film prints, which were discovered at BBC Enterprises in 1978. The negative of "The Rescue" is a dub from the positive print.

They all return to the Thal camp — this time with the fluid link — and the Doctor and his party make their farewells and return to the TARDIS. It is revealed that Barbara and Ganatus have been having something of a romance; he kisses her hand just as she is called into the TARDIS. In the later 1960s serials in which they appeared the Dalek design remained virtually unchanged, with only minor variations to the standard colour scheme and appendages. Susan reaches her friends and passes round the drugs, telling them the Thals are looking for peace and food. The Daleks overhear this and imply acceptance to a treaty, asking in return that the Thals help them cultivate the land, but in reality, they are plotting revenge and extermination of their old enemies. The message of peace is conveyed to the Thals, who are invited to collect food from the entrance hall to the Dalek city the following day. They believe this a genuine sign of friendship as Susan promised them that if the message was signed by her name it would be genuine. The more advanced Daleks developed their own technology, which enabled non-Kaleds to become Dalek mutants. A large number then returned to Skaro and began working on time travel technology in conjunction with Theodore Maxtible ( The Evil of the Daleks). (The date is difficult to ascertain, but would have to be somewhere between the 19th and mid-22nd centuries.) Civil war broke out on Skaro, and for a long time the Thals were once more able to live there in peace.

The ramifications of this deal on the history of Doctor Who are difficult to overstate. Indeed, though agents are usually unknown and uncredited workers, this deal was known to have been negotiated by future British television legend and studio boss Beryl Vertue — mother of Sue Vertue, and mother-in-law of Steven Moffat.

Alan Wheatley was chosen to portray Temmosus, the leader of the Thals, having worked with William Hartnell in The Flying Doctor episode "The Changing Plain". In Remembrance of the Daleks (1988) [6] and the episodes " The Parting of the Ways" (2005) [7] and " Doomsday" (2006) [8] the Doctor states that Dalek casings are constructed from "bonded polycarbide", with this material being referred to as "dalekanium" in The Dalek Invasion of Earth (1964) [9] and " Daleks in Manhattan" (2007). [10] The casing is depicted as being impervious to most projectile and energy weapons, although not indestructible. In various episodes Daleks are shown being damaged or destroyed by overwhelming firepower, their own weaponry and falls from a height. [11] In addition, in Revelation of the Daleks (1985), they are said to be vulnerable to "bastic-headed bullets". [12] In appearances from 2005 onwards a Dalek's defensive capability has been shown to include an invisible force shield, with the eye remaining a weak point.

Background

This story was intended to feature a Glass Dalek, but this was changed due to budget constraints. (The idea of the Glass Dalek was created by David Whitaker only for his novelisation of the story. A Glass Dalek did however later appear in the Sixth Doctor story, Revelation of the Daleks.) In Revelation of the Daleks (1985) Davros creates a new breed of Dalek mutants to command. He uses as source material the severed heads of terminal human medical patients in the Tranquil Repose mausoleum and suspended animation facility on the planet Necros. During the early stages of the conversion process the victims retain some memory and awareness of their humanity, but by the end of the metamorphosis they have become fully Dalek in nature, if not appearance. [12] Despite all these defeats the Daleks were never entirely wiped out and the Time Lords predicted a time when the Daleks could become the dominant life-form in the cosmos. As a result of the Doctor's intervention Dalek 'history' was massively changed. (See The second history of the Daleks). In Revelation of the Daleks (1985) Davros creates an army of Dalek mutants by manipulating DNA extracted from humans on the planet Necros, where the terminally ill and the dead are being stored in suspended animation. [12] These Necros Daleks are portrayed in the serial as a rebel faction while the grey Daleks from the Dalek home-world of Skaro, seen in the final episode, serve the Supreme Dalek. [49]

Although the plot's development hinges on the discovery by the Daleks that they have grown dependent on Skaro's radiation to survive, this fact has only sporadically been referenced by later stories, which present Daleks as galactic conquerors who routinely travel away from Skaro and conquer other worlds. The Dalek World’s Inside a Skaro Saucer provided David Whitaker and Terry Nation's answer to this discrepancy: all Dalek flying saucers are outfitted with "radiation rooms" where Dalek soldiers must come at least once a month to get themselves bombarded with all the radiation they need. The 2020 audio drama, Return to Skaro, would offer the explanation that the next generation of Daleks, having been suspended in a radiation-free environment for decades, overcame their dependence on it. Return to Skaro also tries to reconcile the apparent death of the Daleks in this serial with their subsequent appearances (the first attempt made in any media to explain this) by retroactively asserting that the next generation of Daleks and the retroactively introduced Dalek Supreme had survived by going into hibernation in a level sealed off prior to the destruction of the Daleks' power supply.New Series Dalek variants equipped with a five-pincered claw manipulator appendage and a multi-barrelled Gatling gun-style energy weapon appear in the 2022 New Year’s Day special episode " Eve of the Daleks". Their stated mission is to execute special targets, including the Doctor. [75] Supreme Dalek [ edit ] The Supreme Dalek prop on display at the Doctor Who Experience, December 2014.
