10 Most Powerful Weapons In Doctor Who History

The Flux is so powerful that it had an entire series named after it.

Created by Division under the watchful, rather vindictive eye of Tecteun, the Flux's purpose was to destroy the Thirteenth Doctor before she could further interfere with Division's plans. Seems a bit like overkill to be honest, but then again, considering that nobody has been able to stop the Doctor before, why not go all out?

The Flux was an anti-matter wave that tore apart anything it came into contact with, from planets, to spaceships, to people. It ate several planets, a Dalek fleet, and a Cyber-fleet with ease. It deconstructed things at a molecular level, so there were very few things in the universe that could stop it.

Though Division's quest to destroy the Doctor proved unsuccessful, the god-like power of the Flux was displayed numerous times throughout Series 13. It took an incredibly rare Passenger form with endless space inside it to absorb the entire wave, but had it been left unchecked, it's no exaggeration to say that the entire universe would've been burned to the ground.
