Dalek Supreme Type E

A distinct model of Dalek casing was identified by the Time Lords (PROSE: Dalek Combat Training Manual) as being used by the Supreme Dalek of the New Dalek Empire. (TV: The Stolen Earth/Journey's End)

Characteristics
The Supreme Dalek was a variant of the "Type VIII" Bronze Dalek model, with a red casing, golden sense globes, and extra slat plating connecting the grating section to the weapons platform. As well as extra armour, the Supreme One had a third luminosity discharger, which — as with his other lights — was mounted on a small plate atop his dome. (TV: The Stolen Earth/Journey's End)

The Dalek Time Strategist who, being second-in-command to the Dalek Emperor, outranked the Supreme Daleks, (AUDIO: Restoration of the Daleks, Temmosus) possessed a similar casing albeit coloured purple. Similar to the Dalek Time Controller, the Time Vortex was visible inside the Dalek Time Strategist's extended grating section, which also featured diagonal rings similar to on the Time Controller. (AUDIO: Eye of Harmony, The Enigma Dimension)

Prop
The Supreme Dalek was depicted using a specially created prop. The dome from this Supreme Dalek prop appeared in the Black Archive in The Day of the Doctor. The full prop was later reused to depict the Supreme Dalek in The Magician's Apprentice/The Witch's Familiar.

Other matters

 * In a section on the design of the Supreme Dalek, Doctor Who: The Ultimate Monster Guide suggested that the enlarged gold struts allowed it to plug into flagship systems.
 * The original cancelled design for the Supreme Dalek was similar to the Glass Dalek. It was to be translucent and transparent, showing internal functions and machines as well as the Dalek mutant within.
 * The trailer for AUDIO: Master! depicts the Dalek Supreme in Vengeance, showing it in the modern Supreme casing first seen in The Stolen Earth, but with a black and silver coloration instead of red and gold.
