Dalek leader

Dalek leader was a rank typically given to Dalek drones placed in charge of special missions for the Daleks. Dalek leaders regularly answered to the Supreme Dalek.

Functionally, the role was similar to Command Daleks, or Dalek Commanders, though with less emphasis on direct military missions. Similarly, there were Dalek Section Leaders, who headed scientific and research projects.

History
The Dalek Prime, the earliest Dalek in existence who fired on Davros at their creation, and eventually became the Dalek Emperor, (PROSE: The Evil of the Daleks, War of the Daleks) was rallied around as the first Dalek leader during the coup. (PROSE: Doctor Who and the Genesis of the Daleks) The Emperor's leadership during the early period of the Dalek Empire was enforced by the Black Dalek Leader (COMIC: Plague of Death) and the Red Dalek Leader. (COMIC: Eve of War) The Emperor also referred to his guards as "Black Dalek Leaders". (TV: The Evil of the Daleks)

During the Daleks' conflict against the Mechanoids, the Dalek Fleet was led by a Daleader. (COMIC: The Rogue Planet)

The assassination squad sent to hunt down the First Doctor in a Dalek time machine was under the command of a Dalek leader, though they acted under the instructions of the Black Dalek and the Dalek Prime. The Dalek leader was the final surviving Dalek during the battle with the Mechanoids on Mechanus. In a last bid to kill the Doctor, the Dalek leader set the Mechanoid City to self-destruct, killing everything inside, but the Doctor ultimately escaped. (PROSE: The Chase)

During the Dalek invasion of the 25th century, a Dalek Leader was at the head of an advance party which landed in Kent ahead of a planned invasion of Earth. However, their efforts were sabotaged by a mole. (PROSE: The Small Defender)

The Dalek expedition to Exxilon was led by a Dalek leader. It was destroyed when Dan Galloway blew up the Dalek saucer. (PROSE: Death to the Daleks)

Also acting under the Supreme Dalek, (PROSE: Doctor Who and the Destiny of the Daleks) one Dalek leader commanded the mission to retrieve Davros during the Dalek-Movellan War. The Dalek leader remained with Davros as the other Daleks were sent on a suicide mission to blow up the Movellan ship, but the Fourth Doctor blinded it with his hat and blew it up with an explosive (TV: Destiny of the Daleks) The Dalek leader was among the individuals remembered by the Fourth Doctor as he regenerated. (TV: Logopolis)

The leader of the Death Squad Daleks oversaw the campaign against the Defence Drones in 2021 after being summoned to Earth by the Thirteenth Doctor. Though physically similar to its Bronze Dalek subordinates, its was distinguished by its deeper voice. (TV: Destiny of the Daleks)

Behind the scenes

 * Dalek leaders are usually identified in Target novelisations, as the parent TV serials less commonly distinguish them from the other Daleks.
