10 Most Powerful Doctor Who Villains

10. The Beast

Appearing in the two-parter The Impossible Planet/The Satan Pit, the Beast was essentially the devil itself.

A malevolent being that claimed to predate creation and be the basis for all mythological devil figures, such as Lucifer, it is certainly one of the best ‘nuWho’ villains.

It possesses great intelligence and supernatural abilities, able to play on the deepest, darkest fears of people it meets, and telepathically controls the Ood to relay its rather chilling messages, with the ability to possess humans as well. It’s a shame that it wasn’t given a longer run on the show, as a ‘devil walks among us’ arc could’ve been pretty interesting, especially considering the fact that it looks creepy as the hell from which it came.

Such is its power that it was imprisoned in a pit (hence the episode title) on the planet of Krop Tor for billions of years, kept in place by an energy source, and if it tried to escape it’d be sucked into a black hole, which is what ultimately happens to it.
