Doctor Who: EVERY NuWho Villain And Monster Ranked Worst To Best

Appear in: A Good Man Goes to War.

If you're assembling an army, then you definitely want Doctor Who's version of Sith Lords on your side. The hooded Headless Monks strike in spectacular style with their red energy swords and ability to blast fatal red energy shots from their hands. They also emit a chilling attack prayer just beforehand as if they're softening up their intended victims.

But you wouldn't want to become one. The obvious downside is being headless, and unless you're as rich as Dorium Maldovar then you'll have to settle for your head rotting away on a bog-standard shelf in the Seventh Transept.
