Hey everybody. I found something really interesting I'd like to share with all of you. As this is not confirmed, I'll put here. It's really curious and I think GameFreak really had us on this one since the first generation of Pokémon.
You see there's this Mythical Pokémon that's only obtainable by event in each generation, each one has a characteristic that defines all those Pokémon and that gives a hint that Magearna is in fact a Generation VII Pokémon.
|III||Jirachi||Three points and three bands|
|V||Victini||Five in Roman Numeral|
|VI||Diancie||Six pointed diamonds (on its head)|
|VII||Magearna||Seven teeth (of the gear in its head)|
Definitely interesting, however, still just a theory. Say what you think about this new Pokémon down below. :D
