Seriously dangerous monster of the week - the Ki-Rin.
I've never used this, and I can't recall a dungeon in which I've ever encountered it, but I was looking at it the other day, just idling through the Monster Manual as you do, and read that it could cast spells as an 18th level magic user. It also has the inherent ability to call lightning, presumably at 18th level also. This, if you check the spell out (druidic, I think) gives 20d8 of lightning damage, which is an average of 90 hit points, but it gets worse because any spell that has to do with the sky (err, methinks lightning counts) is doubled in strength. That's an average of 180 hit points in one strike.
Okay, so it's not as bad as the 360 points of damage that all Tiamat's heads can do to you if they breathe on you at the same time and you fail your save, but pretty harsh. And while you're busy smouldering (that assumes you make your save), it then casts the same spell from its list of actual spells it can do that day. Or a wish. Or meteor strike. Or whichever 9th level spell it fancies.
Basically, if you see a Ki-rin coming and it looks angry, run.
Anyone else got a little-known monster that can do some serious damage, and really ought to be better-publicised?

"These rules are flexible and open to interpretation - designed not to cover all conceivable situations, but to allow good Referees and Players the freedom to create and play games of their own design."
from the Lulu download page for The White Box S&W from BHP
"This game is unlike chess in that the rules are not cut and dried. In many places, they are guidelines and suggested methods only. This is part of the attraction of Advanced Dungeons and Dragons"
Over halfway to 90, I started playing AD&D when the Police were a cool band and Punk was wild. I am a father to a ten-year-old Junior Grognard and have now managed to establish a five-strong gaming group made up of him and four of his friends, ages ranging from 10 to 11. Solidly Old-School.
High fives and natural 20s to you all!
