Most annoying enemy in the game?

[tehfusion]

Greetings.

So what enemy do you find most annoying? For me, it's got to be Ice ViVis. You can't do anything for two seconds without getting attacked by one (or more) in Moonlight Tomb. They have long ranged attacks, do high damage via magical attacks, and slow you down - which serves no purpose other than annoying the hell out of you.

So what enemies annoy you?
