I haven’t looked much at the 1980s version of Spelljammer (D&D fantasy spacefaring) or at the new version, but that appears to be a member of the Hadozee species. They look very similar to the Yazirians from TSR’s old science fiction game, Star Frontiers (which I have played), and I think are supposed to be a fantasy version of that species. I know nothing about Hadozee culture. In Star Frontiers, the Yazirians were the smartest of the playable sentient alien races. Spelljammer should have left them simply as smart (fantasy) space-faring aliens. I won’t be surprised if they revert to whatever the 1980s backstory was for the Hadozee, now that their weird slave-race version has sparked backlash. In the 1980s, the Hadozee were monsters, not a playable race,
