There is a hippogrif. And vine blight=assassin vine
Huh- is this made explicit in the book, or does the vine blight just have basically the same thing going on?

This assumes that green slime, yellow mold, etc are in the DMG.
Everything super-weird from the Planescape bestiaries. Particularly the mute race that talks in pictures.
Gorgon and Nymph were the big two I was surprised to see absent. It also would have been nice to see the Kirin, the other two Sphinxes and at least a couple of unique fiends. I've actually never used a demon prince or anything similar in a game, but they are still fun to read about.
The AD&D monster manual had a huge number of "sexy" female monsters, and these were all removed from 5e or given male counterparts in order to be more inclusive, which is not necessarily a bad thing. I'm glad the majority of them were removed, because they were redundant IMO, even if mythology is full of such things. I still wish there was a least one though, just for old times sake.
