Emperor's Personal Guard

The Emperor's Personal Guard (AUDIO: Order of the Daleks) was a Dalek organisation made up of Daleks dedicated to protecting the Emperor Dalek at all costs. They were normal Daleks, but with black domes; in addition, they sometimes possessed claws instead of standard manipulator arms or more powerful gunsticks opposite the standard.

History
During the rust plague outbreak, the Emperor's Guards chased away the Black Dalek Leader so that the Emperor was not infected. (COMIC: Plague of Death)

For whatever reason, either as the Emperor's commanders or simply for their superiority, there were at least two Personal Guard in the execution party that chased the Doctor's TARDIS through eternity in a Dalek time machine. They were destroyed with the rest of the Daleks in the battle with the Mechonoids in the city when they landed on the planet Mechanus. (TV: The Chase)

The Emperor was always guarded by the personal guard in its throne room on Skaro. Their dedication to protecting the Emperor may have superseded their obedience, as they protected the Emperor from the attacking Humanised Daleks despite its commands to keep the fighting out of the room. (TV: The Evil of the Daleks) They were supported by Black Daleks and successfully crushed the rebellion, saving the Dalek race from destruction in the Great War. (PROSE: The Evil of the Daleks, COMIC: Bringer of Darkness, Children of the Revolution, TV: Day of the Daleks)

Although he was not the Emperor, Dalek X, the Dalek Inquisitor General, also had command of two black-domed guards during the Second Dalek War. They had two gunsticks and were destroyed at the end of the war when the Tenth Doctor blew up a disused refuelling station on the planet Hurala, taking Dalek X's Exterminator with it. (PROSE: Prisoner of the Daleks)

An elite Dalek squad that was part of the Emperor's Personal Guard participated in the Dalek invasion of Kantra. Their ship was damaged and the drive gave out while returning to Skaro, causing them to crash on Strellin. Only five, including the commanding Black Dalek, survived and were taken in by Monks of the Brotherhood of the Black Petal who built them new stained-glass casings. The Sixth Doctor helped put an end to their efforts to merge their minds with those of other beings in symbiosis. (AUDIO: Order of the Daleks)

During the Last Great Time War, the guards possessed a claw-like manipulator arm and some had a more powerful gunstick opposite the standard gunstick. The Emperor Dalek had four guards after surviving the Time War but were wiped out by the Bad Wolf in the year 200,100. (TV: The Parting of the Ways)

A squadron of these Daleks were also present during the Dalek Invasion of Earth of 2009. They were presumably destroyed when the Crucible blew up. (TV: The Stolen Earth/Journey's End)

The guards were used by the second Emperor of the New Dalek Paradigm. At least one guard was present on the Dalek Flagship when the Daleks invaded Earth in 2106 using a piece of the Eternity Clock, but did not help the Emperor battle the Eleventh Doctor and River Song. This guard had red armour like the Dalek drones of the Empire, with a black dome. (GAME: The Eternity Clock)

One of these Daleks was present in the Dalek Asylum. Because of the nano cloud affecting Amy Pond's mind, she believed the insane Dalek was a dancing person. (TV: Asylum of the Daleks)

A black-domed Dalek was among the many types of Daleks inside the Dalek City at the time of the Twelfth Doctor's visit. (TV: The Magician's Apprentice/The Witch's Familiar)

Behind the scenes

 * The guards from TV: The Chase do not have black domes although their domes are clearly darker than those of the standard Daleks. As the serial is black and white, their true colour is unknown. The SFX Dalek merchandise identifies this Dalek as a "Guard Dalek". Its dome is coloured blue and the bands around its midsection are gold, reminiscent of the standard Daleks from the film Dr. Who and the Daleks, the 1965 retelling of TV: The Daleks starring Peter Cushing.
 * Daleks with black domes are often seen taking part in battles and conflicts depicted in the Dalek Wars section of Doctor Who: Battles in Time magazines, as a result of promotional images of the black-domed Daleks being inserted into the scenery of the battles.
 * According to the non-narrative source REF: Doctor Who: Aliens and Enemies, the Personal Guard also made up the High Council of Daleks, of which the Dalek Supreme was also a member.
 * Black-domed Daleks appear on the cover of the novelisation of The Evil of the Daleks, as well as some of the covers for Big Finish Dalek stories, including The Apocalypse Element and all six instalments of Dalek Empire III.
