Temporal Weapon Dalek

Temporal Weapon Daleks were Daleks armed with Temporal Cannons created by the Eternity Circle that could erase its victims from history during the Last Great Time War.

They were identical to the bronze Dalek drones with the exception of their weapons platform, which was very similar to Special Weapons Dalek, with a single, large cannon rather than a gunstick and manipulator arm. However, their cannons utilised temporal radiation mined from the Tantalus Eye. It would flow 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. They were also durable enough to withstand fire from a Dalek gunstick, although it could still damage them.

The War Doctor noted their similarities to the Time Lord De-mat Gun and Rassilon's gauntlet which function on the same principle.

The Eternity Circle planned to create a new paradigm of these Daleks and spread them throughout the universe through the use of the Daleks' progenitors. However, the new paradigm was never deployed because it and the Eternity Circle were erased from history by the War Doctor and Borusa. (PROSE: Engines of War)
