Dalek drone

The Dalek drone was the most common Dalek model. (DW: Victory of the Daleks, VG: City of the Daleks) They were used as the main "foot soldier", which led to them very occasionally being called warrior Daleks. (EDA: War of the Daleks)

Variations

 * Pre-Time War
 * Post-Time War
 * Post-Resurrection drone

Pre-Time War

 * The original Daleks created by Davros who had grey silvery and black hemispheres on his MERC (Mind Enhanced Roving Chair). Davros described them as his Mark III Travel Machine. (DW: Genesis of the Daleks)
 * Later there were silver Daleks without slats and light-coloured skirt balls. The Daleks on Skaro which depended on static electricity from the floors of the Dalek City had no slats (DW: The Daleks). The Daleks seen in England during the 22nd century Dalek invasion had radio dishes mounted on their backs for external power (DW: The Dalek Invasion of Earth). The Daleks later had horizontal slats. (DW: The Chase onwards)
 * Later, the Daleks readopted the grey colour scheme (DW: Day of the Daleks). The Renegade Daleks retained this scheme during the Imperial-Renegade War while Davros' Imperial Daleks had a separate colour scheme (although these were effectively a different variant of Dalek). (DW: Remembrance of the Daleks)

During and after the Time War
During the Last Great Time War, the new Standard Dalek basic design had no major alterations except for an expanded base and an overall heavier, more solid look. The Daleks also had a metallic brass finish. The ear-bulbs were much larger and cylindrical and both the eyestalk and indicator lights glowed blue.

This Dalek design was also more advanced, with 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.

It was also able to regenerate itself by means of absorbing electrical power and the DNA of a time traveller. The manipulator arm was also able to crush a man's skull in addition to the technology interfacing abilities shown by earlier models (DW: Dalek).

At least the Cult of Skaro could also remotely interface with technology without using the manipulator arm and extract information from brainwaves using manipulator arms, killing the person from whose mind the brainwaves had been extracted. (DW: Doomsday)

The Daleks which escaped the destruction of the Crucible (DW: Journey's End) camouflaged themselves as 'Ironsides' which were supposedly created by Edwin Bracewell. These Daleks were khaki-green coloured, probably because it was a self-applied paint job in order to perpetuate the deception that they were obedient war robots. Following the restoration of the Dalek race, the standard Daleks became a bright red colour, but were otherwise no different from their superiors. (DW: Victory of the Daleks) The original three Daleks were then destroyed by their "superior" successors. However, it should be noted hundreds of "Time War" Daleks were sent into the Void. (DW: Doomsday)


 * However, the Time War design of the Daleks in also used by them in the Second Dalek War, in NSA: Prisoner of the Daleks, which is set before the Time War. It is possible that the Daleks which started the war, seen in DW: Frontier in Space & Planet of the Daleks, upgraded their casings after failing to retrieve their army in Planet of the Daleks, and the design was later used to fight the Time War.
