Official statements (rewritten)
The Pokémon Company noted on Twitter that a ‘mightiest’ Magikarp will appear in a special Tera Raid and encouraged players to try the encounter before the event ends.
The company also warned that areas such as Casseroya Lake will be unusually crowded during the event, with a higher-than-normal chance to meet Pokémon bearing various Marks.
Finally, The Pokémon Company confirmed that the water-type mass outbreaks are active in both Pokémon Scarlet and Violet and the related 'Zero' content for the duration of the event.
Why this matters
Tera Raid Battles and Mass Outbreaks remain core features of Scarlet and Violet’s endgame, and time-limited events like this one give collectors and competitive players targeted opportunities to capture marked or rare specimens.
The inclusion of a Magikarp with the Mightiest Mark in a Dragon-type Tera Raid is notable for trainers looking to test Tera mechanics or add unique-marked Pokémon to their collections.
Players on Nintendo Switch can access the event through the in-game Tera Raid interface and Mass Outbreak hotspots.
