10 Most Powerful Weapons In Doctor Who History
2. The Reality Bomb
Davros created the Reality Bomb as a superweapon capable of annihilating all matter in the multiverse - all matter that wasn't Dalek. It could essentially destroy all of reality, and in fact, all realities across the multiverse in one fell swoop.
To get the device to function, the New Dalek Empire had to steal planets and moons from across time and space. Once assembled into a specific arrangement, the Reality Bomb could then target and cancel out the electric field holding atoms together, disintegrating the molecular bonds of anything Davros targeted.
The Daleks' entire mission is to become the dominant life form in the universe, and fair play to them, this was a very creative way of making that happen.
Fortunately, the Tenth Doctor and many of his companions successfully stopped Davros and the New Dalek Empire. The Reality Bomb and the Crucible were destroyed, and the planets and moons were returned to their natural places and times.
The weapon was tested before this happened though, and it proved effective against a small group of humans - a mere taste of its destructive capability.
