Ahead of Pokémon Day 2020, held on Feb. 27, The Pokémon Company announced a new Mythical Pokémon is coming to Pokémon Sword and Shield. Details on the new Pokémon will be revealed on Feb. 27. The new Pokémon is also expected to star in the upcoming Pokémon animated film, Coco. (Not that Coco.)

The announcement was posted in Japanese on the official website and translated by Pokémon website Serebii. Alongside the reveal, Sword and Shield will also get a “special Max Raid Battle” and a new event in Pokémon Go, Serebii reported. There’s no further information on what to expect from the new Mythical creature.

Three Legendary Pokémon already exist in Sword and Shield: Zacian and Zamazenta, the two dog-like Pokémon, and a mysterious Legendary called Eternatus. A few new Legendary Pokémon are expected with Sword and Shield’s upcoming expansions, too — Cubfu, Urshifu, and Calyrex.

Feb. 27 — Pokémon Day — is the anniversary of Pokémon Red and Green’s Japanese release date. This year, Pokémon Day 2020 is the 24th anniversary of the two games’ debut in Japan. (Pokémon Red and Green was released in the United States on Sept. 28, 1998.) Pokémon Day is recognized by the Japanese Anniversary Association, a non-governmental entity that tracks commemorative holidays in Japan. Eevee’s got one of its own, too.
