Doctor Who: 10 Most Underrated Villains And Monsters
9. The Slitheen - Aliens Of London/World War Three, Boom Town
Yes, the farting aliens. It's a shame that Russell T Davies didn't restrain himself a bit more on the flatulence jokes when scripting the first two-part story of the revival era, because there's some brilliant political satire at work here.
The Ninth Doctor and Rose Tyler return to London a year later by accident and witness an alien spaceship hitting Big Ben and crashing into the Thames. What seems like an extra-terrestrial invasion at first becomes something much more complicated. The aliens are already here and they're about to get their claws on the nuclear launch codes.
Again, the whole affair is undermined somewhat by both fat and fart jokes. But as both a funny and chilling commentary on the War on Terror and the then current Tony Blair administration, its uncompromising and right on the money.
Just like The Android Invasion, it takes inspiration from Invasion of the Bodysnatchers and uses that fear to deliver a political message on how the real villains are often hiding inside our own government that is sadly still all too relevant today.
