Supreme Dalek



The Dalek Supreme, also known as the Supreme Dalek, Black Dalek, and the Dalek Controller, served in the role of an elite or commander Dalek, however occasionally a Gold Dalek was used for similar purposes. (DW: Day of the Daleks)

The Dalek Emperor also similarly used Black-domed Daleks as lieutenants. (DW: The Evil of the Daleks)

History
Dalek invasion of Earth

During the 22nd century Dalek invasion of Earth (2157 - 2167) a Black Dalek known as a Supreme Controller directed the Bedfordshire operation. It had a terrifying pet called the Slyther which it used to let roam free around the mines at night killing those it found. Its voice was considerably higher than the other Daleks. A black and silver coloured Dalek referred to as the Saucer Commander was also used during this invasion. (DW: The Dalek Invasion of Earth)

Alternative timeline of the 22nd century

The Black Dalek appeared to have been replaced by a Gold Dalek in an alternative timeline in which World War III had occurred in the 1970s, enabling the Daleks to take over. (DW: Day of the Daleks)

Though the World War III timeline did get "erased", the Gold Dalek may have come from the main timeline, via time travel.

Dalek invasion of Spiridon

On the planet Spiridon, a Dalek Supreme in black and gold trim was used to represent a member of the Supreme Council of Daleks, with an eye-stalk that lit up when it was speaking. (DW: Planet of the Daleks)

Dalek Supreme also led the Daleks on the planet Kembel, as well as dispatching a Dalek execution squad. (DW: The Daleks' Master Plan, The Chase).

Later, the Black Dalek was replaced by the Dalek Emperor, which used black-domed Daleks as lieutenants. (DW: The Evil of the Daleks)

Dalek-Movellan War

The Dalek Supreme was the supreme commander of the Daleks during the war with the Movellans. A Dalek lieutenant, a Dalek of a darker shade of grey than the rest, was also of an intermediate rank at that time. (DW: Destiny of the Daleks)

Following the Dalek-Movellan war, the Supreme Dalek was a fully black Dalek, with white bumps instead of the usual grey ones, and a more hollow voice. (DW: Resurrection of the Daleks)

Imperial-Renegade Dalek Civil War

A schism developed between the Daleks led by the Dalek Supreme and those still loyal to their creator Davros. (DW: Resurrection of the Daleks, Revelation of the Daleks, Remembrance of the Daleks)

During the civil war, the Dalek Supreme was the leader of the Renegade Daleks that opposed the Imperial Daleks commanded by Davros, now calling himself the Dalek Emperor. The Dalek Supreme ended up as the last surviving Dalek on Earth. The Doctor convinced it that it had no purpose, at which point, in a state of confusion and distress, it destroyed itself. (DW: Remembrance of the Daleks)

Last Great Time War

During and after the Last Great Time War, the Dalek Supreme had once again been replaced by the Emperor who used black-domed Daleks as lieutenants; however the Cult of Skaro had Sec, a Black Dalek, as a leader. (DW: The Parting of the Ways, Doomsday, Evolution of the Daleks)

Davros' resurrection

During the resurrection of Davros a Red Dalek was possibly created to serve as Davros's second-in-command until Davros was overthrown (again). He took charge of the New Dalek Empire. His casing has gold ridges similar in appearance to the Genesis Ark around it, and its spheres are also golden. The Supreme Dalek speaks in a deep voice similar to that of the Emperor.
