Time Destructor

The Time Destructor was the "ultimate weapon" developed by the Daleks in their bid to conquer the Universe in the year 4000. The device was capable of accelerating the flow of time, reducing all life and structures to dust in minutes. A full emm of taranium was required to power the device, and this was procured for the Daleks by Mavic Chen. The Doctor and his companions managed to steal the taranium and were pursued by Chen and the Daleks.

After a race across time and space, the Daleks were able to retrieve the taranium and return to their base on Kembel. However, the Doctor activated the Time Destructor, which destroyed the Daleks and everything else on Kembel, reducing them to dust. Unfortunately, the Doctor's companion Sara Kingdom was also destroyed by the device's effects ("The Daleks' Master Plan").
