I've noticed a lot of urban fantasy uses the same types of mythical creatures just putting a slightly different spin on them. There are plenty of books that feature vampires, werewolves, wizards, zombies, etc. I feel there are quite a few really cool mythical creatures that deserve to be featured more often but don't. So my main question is what do you think some of these underused mythical creatures are? Personally I think Sphinxes (greek version), Windigos, and Nucklavee should get more attention.
