Most enemies that come equipped with a giant shield. You know it's always going to be pointed at you, and for some reason, it's always invincible to any and all damage; even damage that is normally suppose to be able to get through anything.
Really, any enemy that has any kind of invincibility. Sucks the fun right out of it if you can't do shit to it. I don't mind if it's to a particular damage type, but all damage? No thanks.
That and teleporting enemies; they always seem like chipmunks on crack. Bouncing around with their laughter and ranged attacks, because you know they always spam all 3.
