Breakfast topic: Scariest monsters

You know the score; you're wiping the sweat off your brow after a particularly hard encounter, when all of a sudden you hear the dreaded "RRrrrrlllllrrrRR" and a swarm of murlocs assault you right, left and centre. Or perhaps you're gingerly making your way through enemy terrain when a fearsome Dwarf attempts to chop your knees off. Either way, we've all had scary moments in WoW.

Which monsters or NPCs do you find the most terrifying?

Personally, I'll never forget the first moments when as a baby Night Elf I ventured into a cavern of spiders. Spiders are fine in real-life, but these digitised versions somehow put a chill in my blood no monster has managed to equal since–apart from perhaps the sudden terror of hearing a Rogue stealthing nearby.
