Kommo-o with the Mightiest Mark is appearing in 7-star black crystal Tera Raid Battles in Pokémon Scarlet and Violet from Nov. 13 at 12 a.m. UTC through Nov. 19 at 11:59 p.m. UTC. The powerful Pokémon has a Fighting Tera Type, and players can catch it only once per save file; those who caught it in a previous event can still battle it for other rewards. Trainers can team up with three others to take it on, including through multiplayer if they have not unlocked black Tera Raid crystals in their own game.
