Kaodi
Legend
I could live with them being unified into a single creature differentiated only by their "anchor" . Supernaturally beautiful probably would mean that their appearance is slightly different for each person that views them. And if they had a "badass form" I think it would more properly be that they are able to clothe themselves with their anchor, rather than a true transformation. So a dryad could touch her tree and be covered in thick wooden tendrils and leaves, an oceanid might be covered in ice, and an oread in earth and stone. Not that I necessarily favour such abilities; they are just a suggestion.
In any case, if it has never happened before, it would probably be interesting if encounters between nymphs and beholders actually had a unique effect. Perhaps a beholder viewing a nymph with all of its eyes is slain, its powers of seeing overloaded by the supernatural appearance of the nymph.
