Imperial Dalek

The Imperial Daleks or gold sphere Daleks were a faction of Daleks loyal to their creator, Davros, rather than to the Dalek Supreme. Among the Daleks, they were known as the Ven-Katri Davrett. They fought for Davros, their new Emperor, in the Imperial-Renegade War, organised into the Imperium.

Appearance
In contrast to the drab grey and black Renegade Daleks, the sleeker Imperial Daleks had casings with white livery with gold sense globes and high-pitched, scratchy voices. These prototype models retained the classic eyepiece and plunger manipulator arms, but also featured rounder bases. (TV: Revelation of the Daleks)

Later Imperials had golden eye-stalks and appendages and a lozenge shape on the centre of their weapons platform, while the dome's luminosity dischargers became transparent rings around opaque, flattened gold discs. The ends of their manipulator arms also became slightly funnel-shaped and slotted on two sides to fit into machinery. The base units of these new Imperial casings were also slightly less tapered than was traditional - a change mirrored by their Renegade counterparts. (TV: Remembrance of the Daleks)

A civil war, ostensibly over racial purity, broke out between the original, now Renegade Daleks, and the Imperial Daleks. Imperial Daleks augmented their battle tactics with the Special Weapons Dalek, now converted to the Imperial cause and sporting a tarnished white-and-gold casing. (TV: Remembrance of the Daleks)

Power of flight
The Imperial Daleks could hover and fly (TV: Revelation of the Daleks, COMIC: Emperor of the Daleks!, TV: Remembrance of the Daleks) like Davros himself in his chair, before he assumed the title of Emperor. (TV: Revelation of the Daleks, COMIC: Emperor of the Daleks!)

Early prototypes
Davros owned an injection-type mind control device which he used on a small group of Daleks. These became the first Imperial Daleks, but were subsequently destroyed by the Dalek Supreme's Renegade Daleks or by the Movellan virus. (TV: Resurrection of the Daleks)

Davros experimented with a new kind of Dalek (which appeared to be an Imperial Dalek prototype) at the Tranquil Repose funerary complex on Necros, using parts from cryogenically frozen bodies. Some, like Arthur Stengos, he decapitated, modified and placed — still living — into a Glass Dalek casing. During the conversion process, Stengos' personality alternated between that of a human and that of a Dalek. (TV: Revelation of the Daleks)

Orcini set off an explosion in Davros' bunker, killing many of the prototype Imperials. Other Daleks loyal to the Dalek Supreme then apprehended him to take him to Skaro for trial. (TV: Revelation of the Daleks)

Beginning of the Civil War
Accounts differed as to how Davros went on to being placed on trial on Skaro to being at the head of a whole army of Imperial Daleks loyal to him.

According to one account, as part of a long-term strategy, the Sixth Doctor himself rescued Davros so that he could further develop the Imperials and cause the eventual Imperial-Renegade Dalek Civil War. Taking him to Spiridon, the Doctor showed Davros the cache of four million Daleks (COMIC: Emperor of the Daleks!) whose freezing the Third Doctor had witnessed. (TV: Planet of the Daleks) Davros began reanimating this army and spent a whole year experimenting on them, giving them new, improved casings as well as programming them to be loyal to him rather than the Golden Emperor.

When the Golden Emperor's Daleks, led by the Black Dalek himself, were directed to his hideout by the Seventh Doctor, Davros unveiled his new army and demanded all other Daleks switch allegiance to him. After their refusal, he made short work of the Dalek task-force which had tracked him down to Spiridon and set a course for Skaro, where he exploited a computer virus created by the Doctor to cause every non-Imperial Dalek's casing to malfunction and eventually explode.

The newly-minted Dalek Emperor Davros and his Imperial Daleks were left to resettle the depopulated, ruined Skaro in the aftermath of this first battle, which had also seemed to cost the Golden Emperor his life (although he had initially managed to resist the effects of the virus), while the Black Dalek, stranded on Spiridon, sought to rectify the situation and was left to found the Renegade Dalek faction. (COMIC: Emperor of the Daleks!)

According to another account, however, the Golden Emperor was already nowhere in evidence on Skaro when Davros was taken there for trial, with the Dalek Empire instead being placed under the orders of the sole Supreme Dalek, who was giving some thought to taking on the charge of Emperor, itself.

En route to Skaro, Davros was given an engineered Movellan virus by Thal agent Lareen, giving him the chance to take his creations out with him when they exterminated him, or even, if he somehow survived, to redeem himself to the rest of the civilised universe. Instead, Davros showed the Daleks what power he held over them and pointed out that he chose not to use it. Impressed by his show of loyalty to them, the Daleks attending Davros' trial stopped obeying the black Supreme Dalek, who left in exile, while Davros was crowned Emperor and all the Daleks on Skaro converted themselves to Imperials. (AUDIO: The Davros Mission)

Civil War in full swing
The Imperial Daleks accompanied Davros in Earth in 1815 during the Battle of Waterloo. He planned to replace Napoléon Bonaparte's mind with that of a Dalek and use Napoleon's mind for the Dalek battle computers. (AUDIO: The Curse of Davros)

At a later stage in the war with the Renegades (as he called them) Davros improved the capabilities of his Imperial Daleks (but, from the Renegades' point of view, made them even more impure) by grafting bionic appendages onto the bodies of the Dalek mutants. (TV: Remembrance of the Daleks)

Conclusion of the War
Davros led the Imperial Daleks to Earth in 1963 to get the Hand of Omega. They secured Coal Hill School for a base, controlling the head teacher with a chip in his head and placing a Transmat station in the basement. When this was destroyed by the Doctor with Ace's baseball bat, they landed a shuttlecraft in the school's playground. They engaged in a battle with the Renegades, who seized the Hand, but interference by the Seventh Doctor led to the Imperials acquiring it. The Doctor tricked Davros into using the Hand of Omega (TV: Remembrance of the Daleks) to detonate Skaro's second sun, (PROSE: The Stranger) which caused it to turn supernova and destroy Skaro. Davros escaped his burning mothership in an escape pod. (TV: Remembrance of the Daleks)

Defeat of the Imperial Daleks
According to one account, Davros went into stasis inside his escape pod, which was eventually acquired by a garbage ship, the Quetzel, on which the Eighth Doctor and Sam Jones also ended up. Brought to a resurrected Skaro, Davros realised that the Imperial Daleks had been annihilated in the Hand of Omega incident, but also that even with no modifications on his part, some of the Dalek Prime's Daleks — formerly the renegades, but who now considered themselves the "true" Imperials — were sympathetic to Davros and his ideals.

Davros's trial drove this portion of the Dalek City's population to reveal themselves, and they were destroyed by the Prime-leaning Daleks in the ensuing battle. Davros was seemingly executed, although he had reason to believe the Spider Dalek responsible for the deed was actually loyal to him and would fake his death while taking him to safety. In any event, these events left Skaro under the control of what had once been the Renegade Daleks, the Imperial cause exterminated for good. (PROSE: War of the Daleks)

Defeat of the Renegade Daleks
According to other accounts, however, only Davros's mothership was lost in the blaze of Skaro's sun. With Davros gone, a new Dalek Emperor took charge of the Imperial Daleks and continued the War, successfully taking back Skaro and other major bases from the Renegades. With the competition eliminated, the Davros-loyal Dalek Empire turned their minds to fulfilling Davros's ambition of overthrowing the High Council of Time Lords, thus sparking the Last Great Time War. (PROSE: Dalek: The Astounding Untold History of the Greatest Enemies of the Universe)

In yet another account, positing the survival of an Imperial Dalek faction beyond the Shoreditch Incident, Davros' escape pod entered the Time Vortex and was found by a Nekkistani ship, whose crew was quickly murdered by Davros. The Eighth Doctor, Samson Griffin and Gemma Griffin found the Nekkistani ship in the vortex and the Griffins boarded the ship to investigate. Davros exacted his revenge by sending them back to Earth, wiping the Doctor's memory of them and operating on the TARDIS. On Earth, Davros recreated a race of Imperial Daleks.

They conquered the planet, leaving only the area where Samson lived free from Dalek control. When the Doctor, Charley Pollard and C'rizz returned from the Divergent Universe, Davros was waiting for them. Davros' mind had become fractured between his own personality and that of "the Emperor". A series of events led to the Doctor actually giving the Daleks their Emperor and letting them leave Earth. Gemma was killed. Davros left Earth with his Daleks, the Emperor personality dominant. (AUDIO: Terror Firma)

Davros eventually rejoined the formerly-Imperial Dalek Empire (PROSE: Dalek: The Astounding Untold History of the Greatest Enemies of the Universe) in time to seemingly die in the jaws of the Nightmare Child during the "very first year" of the Time War, by the recollection of the Tenth Doctor. (TV: The Stolen Earth)

After the Time War
At least one Special Weapons Dalek was among the insane Daleks contained in the Dalek Asylum planet. It appeared to be one of the inactive and/or catatonic of the Dalek inmates. The planet was obliterated by the Parliament of the Daleks, destroying the Special Weapons Dalek along with all the other Daleks in the Asylum. (TV: Asylum of the Daleks)

At least one Special Weapons Dalek was among the Daleks who operated on the rebuilt Skaro where the dying Davros lived as he called the Twelfth Doctor to him. (TV: The Magician's Apprentice) These Daleks were destroyed by the rejuvenated Daleks from the sewers. (TV: The Witch’s Familiar)

Alternate timelines
In an alternate timeline created by the Black Guardian where the First Doctor never left Gallifrey, and became Lord President, the Imperial Daleks invaded Earth and fought over the planet with other races. This timeline was destroyed when the Seventh Doctor retrieved the Key to Time. (COMIC: Time & Time Again)

Behind the scenes

 * An illustration of the Master's execution is depicted in one instalment of the Doctor Who DVD Files feature Flashbacks, published in its sixty-first issue of the magazine. The Dalek executioners, later identified as the Dalek Prelature in AUDIO: Mastermind, are depicted as hovering Imperial Daleks, identical to those seen in Remembrance of the Daleks.
 * Imperial Daleks features on the covers of Big Finish audio dramas The Juggernauts, The Curse of Davros and We Are The Daleks and In Remembrance, the latter of which takes place partly concurrently with Remembrance of the Daleks.
 * Depending on the player's progress, "Imperial Dalek" is a potential rank for the Metaltron to attain in the video game NOTVALID: The Last Dalek.
