>>54534494some years ago someone posted a leak here on /vp/ about the first draft of the plot of X and Y. Most prominent elements of the draft was that Team Flare was actually aliens from a far planet that came to earth to destroy it. AZ was also an alien of the same species, who came to Earth many years ago alongside Xerneas/Yveltal (who in this version of the story were living weapons) with the same goal, but after befriending Floette he renounced on his plans of destruction.
Fairy types were supposed to be pokémon that came from the moon, alongside other humanoid Lunarians like Diantha.
