What would あなた call the opposite of a manic pixie dream girl?

Not in the sense of "what's the literal opposite in terms of vocabulary" because the last person who responded in that manner was my friend, her response being "sane krampus nightmare grandpa" which, although genius, isn't what i am looking for here.

I ask because one of my OCs, Jesse, is the complete reverse of a MPDG and I need a catchy name. Basically all he does other than (possibly illegally) screwing the MC is bring 発言しました MC's mood down completely and generally make everything もっと見る depressing.
