Best Creature no. 4: Bok (The Daemons)
Minor spoiler for those who haven't watched this totally brilliant Jon Pertwee episode: this dude isn't actually the main monster in
The Daemons, though you wouldn't think that to look at him
. He fills in for his boss for the first few episodes but he could easily have made it on his own if only he'd been able to speak. And he does a pretty respectable job of it too, giving the UNIT troops a run for their money ("Chap with wings there, five rounds rapid," says the Brigadier famously) and doing a bit of menacing hopping about in graveyards. A stone gargoyle come to life, Bok is basically a Weeping Angel, isn't he? Except that even when you're looking at him he can still move, though I'd love to see a game of Grandmother's Footsteps between him and some unfortunate doomed extra. Then again, considering he's made of stone you'd probably hear him coming a mile off!
