X&Y was very overt about this. Even though they all look like modern sanitized Tinker Bells, Fairies have been rooted in portrayals of the inhuman fair folk of myth since their debut. Pretty much every single dex entry and trainer has reinforced this since then. I think Mina might be the weakest example, since she's just disinterested in society instead of being out of touch with reality like Valerie and Opal or pointlessly cruel like Bede and Ortega.
