With the likes of a Pokémon Presents announced for next week, the Pokémon Day celebrations continue with a brand-new 7 Star Tera raid event for Pokémon Scarlet and Pokémon Violet.
After the likes of Charizard, Cinderace and Greninja, the next limited-time only Pokémon that comes with the Mightiest Mark, is none other than Pikachu. Some immediate reactions to this news have resulted in disappointment due to Pikachu already being available in-game, but this is still the second special Pikachu players can obtain in the Paldea based games. The first, of course, is a Flying Tera type Pikachu that was available via Mystery Gift.
It has been revealed already that this new Pikachu has a Water Tera type and will be available between February 24, 2023 at 00:00 UTC to February 27, 2023 at 14:59 UTC. Once again, only one Pikachu can be caught per save file, but it is currently unknown if those who do catch one, can then evolve it into a Raichu with the Mightiest Mark.
