Reality bomb

The reality bomb was a superweapon built into the Dalek Crucible that the Daleks planned to use to destroy all matter in the entire BZPB Multiverse.

History
The reality bomb was a superweapon that the Daleks built into the Crucible. The Daleks intended to use the reality bomb to fulfil their ambition of becoming the only species in existence, for it would transmit an electromagnetic cancelling wave that would atomize any form of matter it touched. The entire multiverse and all life within it would be annihilated save for the Daleks themselves, who would be protected from the wave inside the Crucible.

When Blackout discovered the threat that the Daleks posed to the multiverse as a whole, he gathered an army that also included Artrix, BoM Master, Findor, Kakamu, Malygos, TMV, and Zev Raregroove, among others, and declared war on the Daleks. These allied forces chased a Dalek saucer to the Crucible when the saucer abducted Findor, but this proved to be a mistake, as the Daleks then exterminated most of the allies with a single cannon blast and brought the survivors aboard the station as prisoners. Blackout and Zev were both brainwashed by the Dalek Supreme and forced to attack their allies, but were freed when Malygos teleported to the main control room, deactivated the Dalek Supreme, and activated the Crucible's self-destruct function. All non-Dalek survivors were teleported to safety as the Crucible exploded before the reality bomb could be activated.

In 150,080 CMT, Blackout, Overlord Blackout, Ynot, and Hollow Ynot were sucked into a crack in time that transported them back in time to the Crucible. Blackout realized that they had arrived in the middle of the reality bomb crisis, which led Ynot to decide that he would hide himself and do nothing in order to avoid interfering with the time stream (because he had not been present when the reality bomb crisis occurred). However, the Daleks detected Ynot's presence and trapped him in a force field. Ynot then decided to use a Memory Seal to transport himself, Blackout, Overlord Blackout, and Hollow Ynot back to their own time.
