Temporal Weapon Daleks, (PROSE: Engines of War) also known as Temporal Weapons Daleks, (AUDIO: The Neverwhen) were Daleks created by the Eternity Circle during the Last Great Time War. These Daleks were armed with Temporal Cannons that allowed them to erase their victims from time. (PROSE: Engines of War)
Temporal Weapon Daleks were identical to bronze Dalek drones with the exception of their weapons platform, (PROSE: Engines of War) which was very similar to those of the Special Weapons Daleks, (TV: Remembrance of the Daleks) albeit with a single, large Temporal Cannon (PROSE: Engines of War) rather than a gunstick and manipulator arm, or the alternate energy cannons use by the Special Weapons Daleks. (TV: Remembrance of the Daleks) The Temporal Cannons utilised temporal radiation mined from the Tantalus Eye, which flowed into their targets' bodies through available orifices before erasing them from history. The results of these targets' actions would remain, and memories of them would not be wholly erased. Temporal Weapon Daleks were also durable enough to withstand fire from a Dalek gunstick, although it could still damage them.
The War Doctor noted the similarities of the Temporal Cannons used by Temporal Weapon Daleks to the Time Lord De-mat Gun and Rassilon's gauntlet which functioned on the same principle. (PROSE: Engines of War)
During the Last Great Time War, prior to the creation of the Temporal Weapon Daleks by the Eternity Circle, (PROSE: Engines of War) the Daleks that fought the Time Lords on the planet that the Neverwhen was detonated above transformed into Temporal Weapons Daleks as a result of the time flux caused by the Neverwhen's detonation. (AUDIO: The Neverwhen)
Late into the Time War, the Eternity Circle planned to create a paradigm of Temporal Weapon Daleks and spread them throughout the universe through the use of the Daleks's progenitors. However, these Temporal Weapon Daleks were never deployed because they and the Eternity Circle were erased from history by the War Doctor and Borusa. (PROSE: Engines of War)
Behind the scenes
Temporal Weapon Dalek is one of Dalek enemies used in the Doctor Who: Legacy mobile game. Unlike the cover of Engines of War, which depicts the Dalek as identical to the bronze Dalek drone but with a distinct weapons platform, Legacy's Temporal Weapons Dalek appear as a bronze version of the Special Weapons Dalek.
