Doctor Who: EVERY NuWho Villain And Monster Ranked Worst To Best
73. Slitheen
Appear in: Aliens of London/World War Three, Boom Town.
It's a shame that the fatuous farting has somewhat overshadowed the Slitheen from Raxacoricofallapatorius (yes that last word was a copy and paste job).
Their naked form is one of the more standout alien appearances (more the prosthetic aspect, of course) - the eight feet frame with pitch-black bulbous, sideways blinking eyes and huge killer claws is something you'd encounter at MiB headquarters. They also put on a decent light show when removing their human skin-suits.
The family would be higher, and on the Sunday Times Extraterrestrial Rich List, if only their business venture - selling off the radioactive remains of planet Earth - hadn't literally blown-up in their faces.
