Lost in Dark Sun
Quite a few actually, but I suppose the most well-known is probably the Illithid/Mind Flayer. I’ve never run a combat encounter with one, and am unlikely to ever do so.
That said, I have used them for social interactions with the PCs, mostly because I have this weird idea about making the illithids a Lawful Good people, but changing absolutely nothing else about them.
