Anime characters who should just stop existing

I think every anime has that one character who is both useless to the plot and / or hopelessly annoying. Which character aggrieves you the most? Who should, like the topic says, outright stop existing, so as to cease blemishing your beloved show?

I know some people like him, but my initially thought is Mr. Satan from Dragonball Z. He's annoying. Some of his antics with Buu are mildly amusing, but beyond that... no. Go away. You are stupid.

Almost every single harem character from every harem anime

Miaka from Fushigi Yuugi. She really got under my skin.

Ditto! I couldn't really read much of it because of Miaka.

Well, I think Excalibur from Soul Eater was quite annoying to me. Not as bad as Miaka, but still kind of useless.

I'm of two minds about Excalibur. There are times when he's utterly hilarious. But then he sticks around too long and he becomes annoying. Which is, granted, the point of his character, but still. At least he doesn't show up often... and from what I remember of the manga he actually does serve a purpose after a while in the full storyline, and is less obnoxious...
