Supreme Dalek (Victory of the Daleks)

The first white Supreme Dalek of the New Dalek Paradigm was created as one of five new Dalek types by the Progenitor aboard their last surviving ship above Earth in 1941 when the last three Daleks tricked the Eleventh Doctor into allowing them to activate the Progenitor device.

Creation
The white Supreme Dalek was the first to leave the Progenitor. It ordered the disintegration of the "unclean" Ironside Daleks before confronting the Eleventh Doctor. When a squadron of spitfires, modified for space combat by the Ironsides' android Edwin Bracewell attacked the saucer to disable its pulse weapon, the Supreme coordinated the counter-attack only for Danny Boy to destroy the disk. When Danny Boy began destroying the ship, the Supreme forced the Doctor to let the Daleks escape by revealing that Bracewell was powered by an Oblivion Continuum, which was powerful enough to destroy the Earth. Even though the Doctor and Danny Boy withdrew, the Supreme attempted to detonate the android only for Bracewell to overcome the programming. Nonetheless, the Daleks were able to escape through a time corridor and went on to rebuild their empire. (TV: Victory of the Daleks)

After taking over Goth to quickly build an army, the five founders formed a new Supreme Council and remained the ultimate leaders of the New Dalek Paradigm before their many defeats to the Eleventh Doctor saw them stripped of any power by the institution of the Parliament of the Daleks under its Prime Minister. The Supreme Dalek maintained a token presence in the Parliament, (PROSE: Dalek: The Astounding Untold History of the Greatest Enemies of the Universe) where it was given orders by the Prime Minister.

The Dalek Asylum conundrum
When the Prime Minister made a request to the Eleventh Doctor, Amy Pond and Rory Williams to save the Daleks from the Dalek Asylum, the Supreme Dalek informed the Doctor of the alias the Daleks use to refer to him, "the Predator", and some of the information regarding their mission to the Dalek Asylum. Just as the Parliament was about to destroy it, Oswin Oswald removed any memory of the Doctor from the Daleks' Pathweb from the centre of the Asylum, causing the Supreme Dalek, along with all other members of the Parliament, to forget the Doctor entirely.

The Siege of Trenzalore
When the Question was transmitted from Trenzalore across the universe after the Eleventh Doctor translated it, (TV: The Time of the Doctor) the Supreme Dalek recognised it as the voice of a Time Lord. (PROSE: Dalek: The Astounding Untold History of the Greatest Enemies of the Universe) After the Daleks regained their memories of the Doctor from converting Tasha Lem into a Dalek puppet, (TV: The Time of the Doctor) the Prime Minister went mad upon remembering their foe. Declaring it unfit to rule, the Supreme exterminated the Prime Minister and retook command of the Paradigm, serving as leader of the Daleks throughout the rest of the Siege of Trenzalore. With the situation advancing to total war, the Supreme called in the totality of the Dalek Fleet to perform an orbital bombardment of Trenzalore until its force field finally shattered.

On the advice of the Eternal Dalek, the Supreme Dalek piloted the Parliament of the Daleks to Trenzalore to exterminate the Doctor, but was destroyed, along with all the other Daleks, after the Doctor gained a new regeneration cycle from the Time Lords.

Identification
 The Astounding Untold History of the Greatest Enemies of the Universe confirms that the Supreme Dalek in Victory of the Daleks and Asylum of the Daleks and The Time of the Doctor are the same individual. The Supreme Dalek is not seen, only heard, in the latter story.

Portrayal
Throughout its appearances in Victory of the Daleks, Asylum of the Daleks and The Time of the Doctor, the Supreme Dalek has a deep voice like that of the Dalek Emperor (TV: The Parting of the Ways) and the red Supreme Dalek (TV: The Stolen Earth/Journey's End) and its lookalike (TV: The Magician's Apprentice). Other white Supreme Daleks, such as Supreme Dalek in The Pandorica Opens and the dying Supreme Dalek in The Wedding of River Song, spoke with a standard Dalek voice.

Prop
As with its fellow new Daleks, the Supreme Dalek in Victory of the Daleks was depicted with a specially created prop. This prop was later used to portray the Supreme Dalek in The Pandorica Opens and was distressed to portray the dying Supreme Dalek in The Wedding of River Song.

On 21 April 2010, by which point the Strategist and Scientist had been modified to create the Stone Daleks in The Big Bang, the Supreme made a public appearance in Sheffield alongside the Drone and the Eternal to promote the video game City of the Daleks, forming the same Dalek trio which appeared in The Pandorica Opens.

The Supreme Dalek in Asylum of the Daleks was depicted using a specially created prop constructed according to the modified "New Dalek Paradigm" design.
