>>45874291You are just butchering a handful of centuries worth of history with your arrogance. Personally, I'd take Pixies as the only member of the fae family, but the history is not as simple as such.
Blame The Renaissance for the mess, I'm pretty sure it's its fault.
Fauns, satyrs, imps are, indeed, fairies. Paracelsus did a great job about that, he considered creatures like gnomes and every kind of nymphs as part of the fae folk. Zeus is not a fairy, but his daughter Melinoë is an underworld nymph.
Gallade comes from the Ralts Line, Butterfree learns it as of eighth gen possibly because of its Gigantamax form, Pikachu possibly learns it because of the regional form of Raichu as well as it belongs to the fairy egg group.
I know right Gamefreak does things wrong sometimes, but in this case they know what they are doing
