Slimes in Odin Sphere. They take an insane amount of damage before going down, and you deal very little damage - like 1 HP per hit - with anything other than napalm bombs, which the game never brings up as particularly useful against them and you probably don't have any on you, so you'll be grinding Habaneristos for a while to get stocked up. The slimes will also stun your character if they so much as touch you, and most times this will kill you, since they take huge chunks of health per hit. The game can become a bullet hell of sorts in the more hectic levels, so avoiding them can become a nuisance, even if they're quite slow.
Ghosts in Silent Hill 4: The Room. They're unkillable, they deal corrosive area damage just by standing next to you and they're not bound by walls or doors unless so scripted. So you spend the whole game avoiding them and navigating around them, which is a nuisance when trying to explore or sort a puzzle out (or dealing with the monsters you can actually kill). You get 2 silver bullets to knock them down instantly, and 5 swords to pin 5 ghosts (out of 15 or so). So they're no fun.

Having just gotten out of Ish's bunker, this is a relief to hear.Casual Shinji said:They're only used in two areas of the game, but they're notorious because of them.
