Reality bomb

"THIS is my ultimate victory Doctor. The destruction of reality itself!"

- Davros

The Reality bomb was a superweapon created by Davros.

Overview
The weapon made use of the 27 planets of the Medusa Cascade captured by the New Dalek Empire along with the unique energy source of the Crucible. This bomb cancels out the electrical field holding atoms together and is capable of wiping the entire universe and all of creation, except for those within or near the Crucible. The reality bomb was planned to destroy all other forms of life except the Daleks, to make them become the only race in the universe..

The Doctor was successful with his companions in preventing the use of the weapon. (DW: Journey's End)


 * The manner that Davros described the weapon suggests that ordinarily the weapon would have destroyed the mainstream universe but when used in conjunction with the time rift of the Medusa Cascade, it was capable of destroying every reality.
