Dalek variant

Although the general appearance of the Daleks has remained the same, the colours and some details of the model have evolved over time. The following entries make mention of both television and non-television portrayals of the Daleks. It should be noted that the canonicity of these non-television portrayals is uncertain.

Standard Dalek
When they first appeared in the 1963 serial, The Daleks, the standard Dalek models sported a silver band along their chest areas, but their mobility was limited to metal walkways in the Dalek City on Skaro, being powered by static electricity and governed by a ruling council. A popular myth is that a "glass Dalek" also appeared in Terry Nation's original story for The Daleks, but due to budgetary considerations did not appear in the serial. The concept of a "glass Dalek" first appeared in David Whitaker's novelisation, and was eventually seen in Revelation of the Daleks.

In The Dalek Invasion of Earth, the size of the base of the Dalek was expanded, and radio dishes were mounted on their backs. These Daleks were more mobile, but still relied on external transmitted power, and were disabled when those transmitters were destroyed. In The Chase, the Daleks were further modified by including what was termed a solar panel array, consisting of wiring and metal slats.

The Daleks of the 1960s serials were mainly silver coloured with blue Dalek "bumps". In The Evil of the Daleks (1967), certain Daleks had black domes. Also, the dishes on their backs had vanished, so presumably they now had independent motive power systems. In the movies based on the first two Dalek serials, Dr. Who and the Daleks and Daleks - Invasion Earth 2150 AD, the Daleks had larger bases as well as larger, jam-jar shaped ear-bulbs, and were painted in a variety of bright colours.

When the Daleks returned to the series in Day of the Daleks, the Daleks adopted a grey colour scheme, with the Dalek commander being painted gold. By the time of Death to the Daleks, the Daleks returned to a silver colour scheme with black bumps, but once again reverted to greys in Genesis of the Daleks. In Remembrance of the Daleks the standard grey-black Daleks were part of the Renegade Dalek faction, with the dominant Imperial Daleks sporting a white-gold colour scheme.

The Daleks returned to the series in Dalek, with a lone Dalek that had somehow survived the Time War which had resulted in the mutual annihilation of both the Daleks and the Time Lords. There were no major alterations to the general Dalek design, except for an expanded base and an overall heavier, more solid look. The Dalek also had an all-over metallic brass finish, similar to the gold Dalek commander of Day of the Daleks. The ear-bulbs also resembled the movie versions, and the eye stalk glowed blue. This Dalek design exhibited abilities not seen before, including a swivelling mid-section that allowed the Dalek a 360-degree field of fire, and a force field that disintegrated bullets before they struck it. In addition to the ability to fly, it was also able to regenerate itself by means of absorbing electrical power and the DNA of a time-traveller. The "plunger" manipulator arm was also able to crush a man's skull in addition to the technology interfacing abilities shown by earlier models.

Non-television Daleks
The following Daleks have never featured in any television appearances:

Spider Dalek
Spider Daleks were a proposed design by John Leekey for an early version of the Doctor Who television movie to be produced by Amblin Entertainment in 1994. The script was rejected and it was the Matthew Jacobs scripted television movie that saw production in 1996. The Spider Daleks ultimately appeared in John Peel's novel War of the Daleks, depicted as creations of Davros. Spider Daleks are slightly larger than normal, but with eight legs. They are more manoeuvrable than standard Daleks, but more vulnerable at their joints. In the novel, the Thals believed that this design had been abandoned for centuries. Giant-sized versions, known as Striders, are ten times larger than the standard Spider Dalek.

In the Doctor Who Magazine comic strip story Fire and Brimstone (DWM #251-#255), a faction of Daleks from a parallel universe resembled Spider Daleks, and were viewed as abominations by the Daleks of the "main" universe. The comic strip Spider Daleks had a square font in their speech-bubbles, rather than the regular angular Dalek font.

Marsh Dalek
Only featured in the 1964 Dalek annual written by Terry Nation and David Whittaker, these were large, bipedal Daleks that were used to control the Horrokon Monsters on the planet Gurnian. They appear to be a forerunner of the Striders referred to in John Peel's books.

Marine Dalek
Marine Daleks, also introduced in War of the Daleks, are torpedo-shaped with their eyes at the front, and have their gunstalk and a grappling arm parallel to their bodies. They are also larger than the standard Daleks.

Scout Dalek
In Ben Aaronovitch's novelisation of Remembrance of the Daleks the Imperial Dalek faction use a type of scout Dalek which is more streamlined than standard Daleks, with overpowered motors.

Transsolar Discs
The Dalek Annuals (circa.1966-8), the The Dalek Chronicles and later Doctor Who Magazine comic strips frequently depicted Daleks mounted on small flying platforms, circular with a railing around the edge. These were used for operation within a planetary atmosphere, with a fully-enclosed version used in vacuum. The television Daleks never used such apparatus; most recently, in Parting of the Ways, it was established that the Daleks of that era (post- Time War) were capable of flight in space without any external assistance.
