Doctor Who: 10 Most Terrifying NuWho Monsters

10. The Silents (The Impossible Astronaut)

Warning: Video contains flashing images.

The creatures that plagued the Eleventh Doctor in multiple episodes of Series 6, the Silents had a truly disturbing presence.

With someone instantly forgetting them once they look away, it created a consistent air of paranoia in every episode.

We got to see their immense power as well, as they harness electricity to shatter and utterly destroy an innocent woman in the bathroom of the White House.

It's worth mentioning that they were introduced to the Whoniverse at the height of Slenderman's popularity, and their long limbs, suits, and creepy faces are reminiscent of the internet sensation.

They established themselves as omnipresent villains, and were a fantastic addition to the rogues gallery of NuWho.
