This year's Pokémon Day is set to take place on February 27, as reported on Pokémon's Japanese website, and on that day a brand new mythical Pokémon will be revealed.
This Pokémon will star in the upcoming film, Pokémon The Movie: Coco, which is set to release in July of this year. This new Pokémon will, of course, also be available in Pokémon Sword/Shield.
We have no details about this new Pokémon, or when it will appear in the games, so we'll just have to wait for the big reveal.
What are you hoping for?
