Pokémon Scarlet and Violet players can challenge a 7-star Tera Raid Battle featuring Quaquaval with the Mightiest Mark from Sept. 18 at 12 a.m. UTC through Sept. 24 at 11:59 p.m. UTC. The featured Quaquaval has a Water Tera Type and can be caught only once per save data, meaning players who previously caught it during an earlier Tera Raid event cannot obtain another. Trainers can still battle the returning Quaquaval for additional rewards, while players who have not caught it can team up with up to three other Trainers to take on the powerful black crystal Tera Raid. The event requires the latest Poké Portal News, with online participation requiring a Nintendo Switch Online membership, and these Tera Raid Battles are available only in the Paldea region.
