I've been playing Elder Scrolls IV: Oblivion a lot recently, and, i've had my share of annoying enemies on games (Many from Dragon Quest VIII) but the Wraiths on Oblivion just annoy me so much! I cant stand their infernal screeching and the fact they get in the way so i cant get through a door!
Anyway, I was just wondering, what video game enemy/ies annoys you?
