Black Dalek (Daleks' Invasion Earth 2150 A.D.)

A Black Dalek was second-in-command to the Gold Dalek during the occupation of Earth in 2150. (NOTVALID: Daleks' Invasion Earth 2150 A.D.)

The Dalek Survival Guide identified a Black Mine Controller as a member of the Dalek Invasion Force in the version of history "B" relative to the First Doctor's version of history "A". (PROSE: Dalek Survival Guide) In the "A" reality, the Dalek Earthforce was led by the Black Dalek Leader as Supreme Controller, operating the Dalek Supreme Type 1 casing, and supported by a black-and-silver Dalek saucer commander. (TV: The Dalek Invasion of Earth) Incidentally, another Black Dalek supported the Gold Chief Dalek, operating the Dalek Supreme Type 3 casing, who led the Dalek Invasion Force Type 3 in the altered version of history "C" created by the Daleks. (TV: Day of the Daleks, PROSE: Doctor Who and the Day of the Daleks)

Characteristics
The Black Dalek had a casing mostly coloured black, consisting of the dome section, middle section and lower section. As with all Daleks on Earth, it sported a tall black fender at the bottom of the lower section, two cone-shaped luminosity dischargers which stood atop the dome and flashed when the Dalek spoke, coloured red like the Red Dalek, alongside mostly silver accessories; the neck rings which supported its black neck grille, slats across the middle section, middle section bands atop and below the arm sockets, and the eyestalk that connected the eye lens, which appeared as a shining white disc at the face of a black ball, to the dome's pivot, supported by five light blue discs. The left and right arms of the middle section were a gunstick and claw manipulator arm respectively. The sense globes in the Black Dalek's lower section were coloured gold.

Biography
The Black Dalek operated aboard the Dalek spaceship which landed in Bedfordshire, where human slaves were made to mine to further the Daleks' goal to extract the magnetic core of the Earth, which would allow them to pilot the planet like a giant spaceship; having found a fracture in the Earth's crust, the Daleks intended to drop a explosive device through the fracture, which would cause the metallic core to burst out and plunge towards the Sun, killing all humans in the area. (NOTVALID: Daleks' Invasion Earth 2150 A.D.) The Black Dalek, the Red Dalek and two Robomen once patrolled a street of the ruined London, narrowly missing the presence of an older Susan in TARDIS, which they mistook for a simple police box. (NOTVALID: Untitled 1)

Ultimately, the Black Dalek reported that the Earth's outer core had been penetrated and so oversaw preparations for the explosive capsule with the Red Dalek and the Gold Dalek. The Black Dalek ordered Reserve Section Roboman 9 to the mine control centre while Sections 8 and 10 were to continue to patrol the mine area. The Black Dalek presented Dr. Who, the "rebel leader" who had been captured along with Susan and Wyler, to the Gold Dalek, who intended to exterminate him. However, Dr. Who stalled by offering to help neutralise the Daleks' weakness to magnetism. Once the Robomen arrived, Dr. Who seized the control and ordered the Robomen to attack the Daleks. Though the control room was soon secured, Dr. Who and company escaped, creating a distraction and so the capsule was dropped only to explode off-course. As the Daleks were all summoned into the spaceship, they were incapacitated by the magnetic forces. Unable to control itself, the Black Dalek fell down the shaft where the capsule had been dropped, followed by the Red Dalek before the ship itself crashed, destroying all the Daleks on Earth.
