The next Pokémon Scarlet and Violet seven-star Tera Raid Battle event star was accidentally revealed in a sponsored video last week.
Twitter user @SerebiiNet revealed that Hisuian Decidueye will star in this event, which will run from October 6-8 and repeat on October 13-15. The regional mon will be a Mightiest Mark Grass Tera Type, and as always, you can only catch it once per save file, so take advantage while it’s around.
This Hisuian form debuted in Pokémon Legends: Arceus as a Fighting-Grass hybrid. Be ready to fight powerful Grass attacks due to the Tera Type of the battle event.
