A Dark–Tera Type Feraligatr with the Mightiest Mark is now appearing in 7-star Tera Raid Battles in Pokémon Scarlet and Violet, giving Trainers a limited-time challenge to take on. The powerful raid boss is available through Feb. 19 at 3:59 p.m. PST, offering players a chance to catch Feraligatr with its special mark if they can defeat it. As with other 7-star events, expect a tough battle that requires careful team planning and coordination. Trainers who miss the window will have to wait and see if the event returns in the future.
