The Black Dalek Leader, (COMIC: Plague of Death) usually just referred to as the Black Dalek, and briefly as Searcher One Leader, (COMIC: The Archives of Phryne) was the earliest Black Dalek in existence and the second-in-command of the Dalek race, after the Dalek Prime. (COMIC: Duel of the Daleks, Plague of Death, PROSE: The Evil of the Daleks)

Serving as the Dalek Emperor's warlord, (COMIC: The Secret of the Emperor) the Black Dalek also held the rank of Supreme Dalek and oversaw major operations during the early expansion of the Dalek Empire (COMIC: The Archives of Phryne, Return of the Elders, TV: The Chase, PROSE: The Chase) before its ultimate destruction. (TV: The Daleks' Master Plan, PROSE: The Mutation of Time)

During its reign, the Black Dalek Leader did not remain the only Black Dalek in existence (TV: The Dalek Invasion of Earth, PROSE: Legacy of the Daleks, AUDIO: The Destroyers, Masters of Earth, The Curse of the Daleks, Return to Skaro) but it was unquirely valuable to the Dalek Prime, who considered in irreplaceable. (COMIC: Plague of Death, PROSE: The Mutation of Time)

Establishing power on Skaro
During the days when the Daleks remained confined to the Dalek City on Skaro, the Black Dalek Leader was feared among the Daleks as the enforcer of the Emperor's will. The Emperor summoned the Black Dalek to deal with Zeg after he challenged the Emperor's authority. Its weapon was unable to penetrate Zeg's metalert casing. (COMIC: Duel of the Daleks)

When the Daleks developed a means of space travel, the Emperor led an invasion force off Skaro to conquer other planets, (COMIC: The Amaryll Challenge) leaving the Black Dalek in charge of the Dalek City. When the Daleks were threatened by the outbreak of a rust plague, the Black Dalek was infected in such as way that it could be used as a vessel to transmit the plague to other Daleks. The Emperor returned to Skaro to deal with the situation. The Emperor's guards chased the Black Dalek away to protect the Emperor. The Emperor then found the Black Dalek by the Brain Machine, rusting away, resigned to its fate, ashamed as it was of letting other Daleks die. The Emperor claimed the Black Dalek was too valuable to lose and sent it to the recasting furnace to be repaired. (COMIC: Plague of Death)

Leading the early conquests
After its recovery, the Black Dalek led a force of Daleks to the planet Phryne in search of new technologies as war with the Mechanoids became evermore certain. It took on the title of Searcher One Leader, denoting its command over the saucer, Searcher One. The Daleks successfully occupied the planet, although many Phrynians went into hiding to form a resistance movement. (COMIC: The Archives of Phryne)

The Emperor called a meeting with the Black Dalek and a Red Dalek when the presence of the One in a Million Dalek threatened to cause a civil war on Skaro. (COMIC: Shadow of Humanity)

Once the Daleks discovered the location of Earth, (COMIC: The Road to Conflict) the Black Dalek was also present on the Emperor's ship when the Daleks first ventured into the solar system. The Daleks retreated in the face of resistance but vowed to return. (COMIC: Return of the Elders)

22nd century Dalek invasion
In 2157, the Daleks began a decade-long occupation of Earth and its colonies. Though the Black Dalek Leader was not involved, numerous other Black Daleks took part in the invasion, all of which were lost at the Daleks' defeat, including the Supreme Controller, the Dalek Saucer Commander, (TV: The Dalek Invasion of Earth), the Black Dalek Interrogator, (AUDIO: Masters of Earth) and the head of the research facility DA-17. (PROSE: Legacy of the Daleks)

After the failure of the invasion, the Daleks identified the Doctor and determined the role he played in their defeat. The Black Dalek, under orders from the Dalek Prime, (PROSE: The Chase) ordered an assassination squad to pursue his TARDIS in a Dalek time machine and exterminate the occupants. The squad failed. (TV: The Chase)

As the Supreme Dalek
Beginning in the 36th century, the Daleks began the conquest of hundreds of planets in the Ninth Galactic System and the Constellation of Miros, avoiding human space for hundreds of years. (TV: Mission to the Unknown) In the 40th century, they finally returned and began preying on human space in secret. A subordinate Black Dalek informed the Black Dalek Leader, as the Supreme Dalek, about the success of the Dalek incursion on M5. (AUDIO: The Destroyers)

During the same period, the Black Dalek Leader presided over the re-election of the Dalek Prime as Emperor. The Black Dalek obliterated the entire Red Extra-Galactic Squadron when their commander denounced the Emperor for continued failure to defeat humanity. (COMIC: The Secret of the Emperor)

Destruction
In 4000, the Black Dalek oversaw the Dalek operations on planet Kembel. It led the conference which founded the Great Alliance with the emissaries from the Outer Galaxies, intent on invading the solar system once more. (TV: Mission to the Unknown, PROSE: Mission to the Unknown, WC: Mission to the Unknown)

Some months later, the Supreme Dalek held another conference as the Alliance completed preparations on the Time Destructor with the taranium supplied by Mavic Chen. The theft of the taranium by the First Doctor put the Black Dalek on edge, and it callously executed a number of its erstwhile allies, and even other Daleks, for failure during the recovery efforts.

Even after the successful recovery of the taranium core, the Doctor, Steven Taylor and Sara Kingdom managed to hijack the Time Destructor itself, using the Black Dalek as a shield to discourage the other Daleks from attacking them. The active Time Derstructor wiped out all Daleks on the planet, including the Black Dalek (TV: The Daleks' Master Plan) This was a massive blow for the Dalek Empire as the Dalek Prime considered both the fleet and the Black Dalek irreplaceable. (PROSE: The Mutation of Time)

Legacy
When the Second Doctor returned to Skaro, he encountered another Black Dalek. He wondered if it was the same Supreme Dalek from Kembel at a point in time prior to its destruction. However, by this stage, Black Daleks had become far more common and many were present in the City, indicating to the Doctor that the Black Dalek Leader was long dead. Indeed, it had been almost a millennium since the events on Kembel and the Daleks were engaged in the destructive Great War. (PROSE: The Evil of the Daleks)

After the Dalek Civil War, (TV: The Evil of the Daleks) Black Daleks became outranked by the new Gold Daleks (PROSE: Doctor Who and the Day of the Daleks) who constituted the elite among the Daleks. Yet, in the words of the Eighth Doctor, Black Daleks remained "a lot nastier and smarter" than their Grey Dalek, Blue Dalek and Red Dalek subordinates. (PROSE: War of the Daleks)

Black Daleks continued to act as Supreme Daleks (TV: Resurrection of the Daleks, Remembrance of the Daleks) and notable individuals also acted as the Emperor's enforcers, including members of the Imperial Guard, (AUDIO: Order of the Daleks) Dalek X, the Dalek Inquisitor General during the Second Dalek War, (PROSE: Prisoner of the Daleks) and Cult of Skaro leader Dalek Sec. (TV: Doomsday, Daleks in Manhattan/Evolution of the Daleks, PROSE: Birth of a Legend)

Identity
The Black Dalek Leader first appeared in Duel of the Daleks and became a recurring character throughout The Dalek Chronicles. For years, there was no definitive link between the Black Dalek Leader, the Black Dalek which appears in The Chase, or the Supreme Dalek which features in Mission to the Unknown and The Daleks' Master Plan.

The connections were made by John Peel in his novelisations: The Chase, Mission to the Unknown, The Mutation of Time and The Evil of the Daleks. Peel wrote these as interconnected works and established the Black Dalek from The Chase and Mission to the Unknown/The Daleks' Master Plan as one and the same in the process.

Furthermore, the novelisations take inspiration from The Dalek Chronicles, most notably in the form of the Dalek Prime's bulbous gold casing. For the Black Dalek, it is considered "irreplaceable" in The Mutation of Time and remembered as "the second in command of the Daleks race" in the novelisation of The Evil of the Daleks, matching the status of the Black Dalek Leader as established in Plague of Death.

As a result, it could be said that the Black Dalek Leader became the first ever character originating in spin-off media to make its way into the TV series, if retroactively.

The Dalek Supreme seen in Daughter of the Gods could also be the same individual, as the story takes place in an alternate timeline in which the Daleks were never defeated on Kembel. However, no link has been drawn to establish this.

Other matters

 * The Black Dalek was voiced by either David Graham or Peter Hawkins in its original televised appearances. Nicholas Briggs provided its voice for the novelisation audiobooks, as well as the reconstruction of Mission to the Unknown by the University of Central Lancashire.
 * Because The Dalek Chronicles went through frequent art shifts, the Black Dalek Leader often changes colour and design between stories. In Duel of the Daleks, it is black and silver; in Plague of Death, it is black and gold; and in The Archives of Phryne, it is black, gold and silver, resembling the Black Dalek from Dr. Who and the Daleks, who replaced the Glass Dalek as the leader of the Dalek City in this retelling of The Daleks starring Peter Cushing (which is not considered a valid source by this Wiki).
