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

Appears in: The Sontaran Stratagem/The Poison Sky.

Suppose it helps to remain undefeated in warfare when you're far and away from the battlefield. Of course, it's a general's job to formulate strategies so Staal isn't going to be marching into battle, no matter how innate his love of fighting is.

In the absence of all-out action, Staal comes up with a sinister stratagem that turns the eco game-changer ATMOS device into an emitter of noxious gas around the whole world, thus converting the Earth into one super hatchery for cloning billions of Sontaran soldiers.

Staal talks the Sontaran talk with the usual humiliating and humorous putdowns of humanity, and that perma-resting frowny face of his shows he's clearly still sore about missing out with the metaphorical and physical big boys in the Time War.

The utter shock on Staal's face when he's about to be killed by the human scum Luke Rattigan is priceless.
