Dalek


Daleks are organisms from the planet Skaro, integrated within a tank-like or robot-like mechanical casing. The resulting creatures are a powerful race bent on universal conquest and domination, utterly without pity, compassion or remorse. Various storylines portray them as having had every emotion removed except hate, leaving them with a desire to purge the Universe of all non-Dalek life. Very occasionally they are shown as experiencing other emotions, including fear, although such occurrences are rare.




Collectively they are the greatest extraterrestrial enemies of the Time Lord and series protagonist, the Doctor. Their famous catchphrase is "Exterminate!", with each syllable individually screeched in a frantic electronic voice.

The Daleks were created by writer Terry Nation and designed by BBC designer Raymond Cusick. They were introduced in December 1963 in the second Doctor Who serial, colloquially known as The Daleks. They became an immediate and huge hit with viewers, featuring in many subsequent serials and two 1960s motion pictures. They have become as synonymous with Doctor Who as the title character, and their behaviour and catchphrases are now part of British popular culture. "Hiding behind the sofa whenever the Daleks appear" has been cited as an element of British cultural identity; and a 2008 survey indicated that 9 out of 10 British children were able to identify a Dalek correctly. In 1999 a Dalek appeared on a postage stamp celebrating British popular culture, photographed by Lord Snowdon.

The word "Dalek" has entered the Oxford English Dictionary and other major dictionaries; the Collins Dictionary defines it rather broadly as "any of a set of fictional robot-like creations that are aggressive, mobile, and produce rasping staccato speech". The word and Dalek image have been copyrighted by the BBC, whilst the rights to the Dalek concept reside with the (Terry) Nation estate. The term is sometimes used metaphorically to describe people, usually figures of authority, who act like robots unable to break from their programming; for example, John Birt, the Director-General of the BBC from 1992 to 2000, was publicly called a "croak-voiced Dalek" by playwright Dennis Potter in the MacTaggart Lecture at the 1993 Edinburgh Television Festival.

Externally, Daleks normally resemble human-sized salt and pepper shakers with a single mechanical eyestalk mounted on a rotating dome, an exterminator arm containing an energy weapon (or "death ray") and a telescopic manipulator arm which is usually tipped by an appendage resembling a sink plunger. Daleks have been seen to be able to use their plungers to interface with technology, crush a man's skull by suction, measure the intelligence of a subject, and extract information from a man's mind. Dalek casings are made of a bonded polycarbide material dubbed "dalekanium" by a member of the human resistance in The Dalek Invasion of Earth and by the Cult of Skaro in "Daleks in Manhattan".

The lower half of a Dalek's shell is covered with hemispherical protrusions, or "Dalek bumps", which are shown in the episode "Dalek" to actually be spheres embedded in the casing Both the BBC-Licensed Dalek Book (1964) and The Doctor Who Technical Manual (1983) describe these items as being part of a sensory array, whilst in the 2005 series episode "Dalek", they are shown to serve a function in a Dalek's self-destruct mechanism. Their armour has a forcefield that evaporates most bullets and resists most types of energy weapon, although normally ineffective firepower can be concentrated on the eyestalk to blind a Dalek. Their own energy weapons have also been shown to be capable of destroying them. The eyepiece is a Dalek's most vulnerable spot, and impairing its vision often leads to a blind, panicked firing of its weapon whilst shouting, "My vision is impaired; I cannot see!" Russell T Davies subverted the catchphrase in his 2008 episode "The Stolen Earth", in which a Dalek vaporises a paintball that has blocked its vision while proclaiming "My vision is not impaired!".

The creature inside the mechanical casing is depicted as soft and repulsive in appearance and vicious even without its mechanical armour. The first-ever glimpse of a Dalek mutant, in The Daleks, was a claw peeking out from under a coat after it had been removed from its casing. The actual appearance of the mutants has varied, but often adheres to the Doctor's description of the species in Remembrance of the Daleks as "little green blobs in bonded polycarbide armour". In Resurrection of the Daleks a Dalek creature, separated from its casing, attacks and severely injures a human soldier. As the creature inside is rarely seen on screen, a common misconception exists that Daleks are wholly mechanical robots. As of the new series Daleks are shown to be mollusk-like in appearance, with small tentacles, one or two eyes and an exposed brain.

The voice of a Dalek is electronic; the Dalek creature is apparently unable to make much more than squeaking sounds when out of its casing. Once the mutant is removed, the casing itself can be entered and operated by humanoids; for example, in The Daleks, Ian Chesterton (William Russell) enters a Dalek shell to masquerade as a guard as part of an escape plan.

For many years it was assumed that, due to their design and gliding motion, Daleks were unable to climb stairs, and that this was a simple way of escaping them. A well known cartoon from Punch pictured a group of Daleks at the foot of a flight of stairs with the caption, "Well, this certainly buggers our plan to conquer the Universe". In a scene from the serial Destiny of the Daleks, the Doctor and companions escape from Dalek pursuers by climbing into a ceiling duct. The Fourth Doctor calls down, "If you're supposed to be the superior race of the universe, why don't you try climbing after us? Bye bye!" The Daleks generally make up for their general lack of mobility with overwhelming firepower; a joke among Doctor Who fans goes, "Real Daleks don't climb stairs; they level the building." Dalek mobility has improved over the history of the series: in their first appearance, The Daleks, they were capable of movement only on the conductive metal floors of their city; in The Dalek Invasion of Earth a Dalek emerges from the waters of the River Thames, indicating that they not only had become freely mobile, but are amphibious; Planet of the Daleks showed that they could ascend a vertical shaft by means of an external antigravity mat placed on the floor; and Remembrance of the Daleks depicted them as capable of hovering up a flight of stairs. Despite this, journalists covering the series frequently refer to the Daleks' supposed inability to climb stairs; characters escaping up a flight of stairs in the 2005 episode "Dalek" made the same joke, and were shocked when the Dalek began to hover up the stairs. The new series depicts the Daleks as fully capable of flight, even through space.
