>Fairy type is a Pokémon type that was just classified recently.In Courmarine City Sycamour, the professor who studies mega evolution, says
>It's only a hypothesis, but I think the bond between Pokémon and Trainer is the key to this new Evolution. But what is this bond, exactly? And why are there examples of Mega Evolution only in the Kalos region? There's still so much we don't know...In XY you, your rival, Korrina, Dianthia, and Lysandre are the only characters to mega evolve.
In ORAS, a game that takes place earlier in the timeline BEFORE it was reintroduced to the world in XY, you, your rival, the two team bosses, two of the admins, Zinnia, Steven, the entire elite four, Wally and Lissia can mega evolve.
Korrina states at one point
>Yes... Mega Evolution is a special kind of Evolution. That said, we still know very little about it. What we know now is that it requires special items. And the most important element is the trust between Pokémon and Trainer.We still know very little about it. And yet it's quite widespread in ORAS.
In XY Mega Stones are stated to be created by the power of Xerneas and Yveltal. In ORAS they come from meteorites that fell to earth. Two things that aren't even remotely similar in nature.
