10 Deadliest Doctor Who Villains

Sontarans are some of the oldest villains to appear on the series, as they popped up in 1973, and have been a major player on the show ever since. They are a race of cloned humanoids who love nothing more than the destruction of their enemies or to experience death at their hands.

Essentially, a Sontaran is little more than a soldier who will either kill or die for the cause — whatever that cause might be. Sontarans will completely annihilate a species if they decide they need to be in conflict with them, and they have set their sights on Earth many times.

In a recent story, they opted to convert the atmosphere of Earth to their liking, and doing so would have wiped out almost all life on Earth. Fortunately, the Doctor found a way to stop them, but it was a close call in the end.

While they're easy to hate as villains, one of the best characters in the series, Strax, was a Sontaran and member of the Paternoster Gang. He was forced to serve as a nurse, having to heal the injured as punishment for being defeated by the Doctor. He's hilarious and attacks every situation with a warrior's resolve.
