Also Chrysalids from X-COM: Enemy Unknown. they scare the crap out of me! D:>
The Chrysalids weren't all that challenging in themselves when I played, yet I still agree that they were the worst in that game, simply because they upset my meta-game. While I liked to advance methodically, always with one or two ready to shoot anything appearing as the others advanced, the Chrysalids - loving to kill civilians and turn them into additional enemies - made this strategy not only impossible to do if I wanted to save civilians, but making me struggle against more enemies than initially anticipated.
This forced me to advance less cautiously, endangering my entire team to all enemies on the battlefield.
Shogun 2...Dunderbuss cav, I've said enough.
Chivalry, the really skilled guy playing a "retreat then attack" Man at arms while constantly spamming the 'laugh' emote. Not only does he draw away half a team from the objective as they follow him like lemmings, but his evil laugh will soon echo in your ears as you find yourself dying to him again and again... (I know, I know, you meant enemies, not people playing in multiplayer...still, my point stands.)
The Aliens in "Aliens vs Predator"...gods be damned, but playing as a marine is scary when these things vomit out of some dark hole or circle you while out of sight, only staying a blip on your radar as you again and again try to keep facing them while staring into the darkness, knowing another one might be sneaking up behind you at that very moment... *shudders*
(At least playing as an alien was fun.)
