The Mythical PokémonZeraora has been revealed today!
It will star along sideLugia in the upcoming movie, Pokémon Movie 21: Everyone's Story [みんなの物語].
Together with the new Ultra Beasts;Poipole,Naganadel,Stakataka and Blacephalon, this was the first instance that any Pokémon (excluding new forms) were added into the roster mid-generation. Being a Mythical Pokémon, it also bears the distinction of being the first Mythical to be added mid-generation.
As such, this Pokémon will be available on Pokémon Ultra Sun & Ultra Moon (and not Pokémon Sun & Moon).
We expect to see distribution details soon, regarding this Pokémon.
Official Sugimori Art :
Given how Mythicals were distributed previously, I expect its Japanese release to be done in-conjunction with some promotion relating to the Movie 21: either via in-cinema local wireless distribution, or pre-order tickets serial code.
