Type V Dalek

The Type V Dalek was a model of Dalek casing identified by the Time Lords, noted for their role in the Exxilon Gambit. (PROSE: Dalek Combat Training Manual)

Appearance
The Type V Daleks were distinguished by their silver casings which featured black sense globes as well as black-and-silver slats on their weapons platforms. (TV: Death to the Daleks, AUDIO: The Dalek Protocol) Following the earlier silver Daleks, the Type III, and the initial grey Daleks the Type IV, the Time Lords identified these Daleks as being essentially Type III Daleks with modified sensor globes. They further identified the prototype Imperial Daleks created by Davros, the Type VI, as being based on the structure of the Type V. (PROSE: Dalek Combat Training Manual) A Dalek recorded in a book by some historians utilised an identically-coloured casing to the Type V, but with the same shape as a Type VIII Dalek. (PROSE: The Whoniverse)

History
After the Dalek war, a ship of silver Type V Daleks travelled to the planet Exxilon in search of Parrinium, the only cure to a plague which the Daleks hoped to exploit, where all of its power was taken by the Exxilon City. The Dalek task-force encountered the Third Doctor and his companion Sarah Jane Smith along with a human expedition. They attempted to gun down the humans, but discovered that the Exxilon City had also drained their power supplies, rendering their gunsticks useless and forcing the Daleks to form an unholy alliance with the humans. While their gunsticks did not work, the Daleks replaced them with machine guns and enslaved the Exxillons in search for parrinium. When their power was restored, the Daleks revealed they were the cause of the Space plague and were about to fire plague missiles to kill the Exxilons and the Doctor as they made their getaway in their ship. However, it and its crew were destroyed by Dan Galloway, who had stowed away on the ship with a Dalek bomb, which he detonated. (TV:  Death to the Daleks) Some years later the Daleks returned to Exxilon after the plague began to infect Daleks. (AUDIO: The Dalek Protocol)

The Time Lords suggested that the prototype Imperial Daleks created by Davros, which they identified as Type VI Daleks, were based on the structure of the Type V. (PROSE: Dalek Combat Training Manual)

A Type V Dalek was an inmate of the Dalek Asylum planet which persisted in the post-Time War universe, with the Eleventh Doctor acknowledged that intensive care housed insane Daleks who had survived encounters with him on worlds such as Exxilon. The Dalek was present when the planet was destroyed in the Asylum Incident. (TV: Asylum of the Daleks)

Behind the scenes

 * The Dalek Handbook takes the appearance of silver Daleks in the Exxilon Gambit as evidence that the taskforce were Daleks native to the 27th century time period whom had been subsumed into time traveling grey Dalek forces from the future, beyond the year 4000.
