Pokémon Scarlet and Violet, developed by Game Freak and released on November 18, 2022 for Nintendo Switch, continue to receive timed online events centered on the Tera Raid system introduced with the titles.
Event summary
- What: 7-star Tera Raid featuring Decidueye with the Flying Tera Type and the Mightiest Mark
- Platforms: Nintendo Switch (Pokémon Scarlet and Violet)
- Catch rule: The featured Decidueye is available as a one-time catch per player
- Availability: Event listed as active through May 21, 2026 at 23:59 UTC, per a Serebii.net update posted May 15, 2026
Serebii.net, a long-standing community news hub, reported the live window for the raid and the core event details.
In journalistic terms: Serebii confirmed that Decidueye will appear in 7-star Tera Raid Battles until May 21, 2026 at 23:59 UTC, and that the encounter is a one-time catch carrying the Mightiest Mark.
Players who successfully catch the raid Decidueye can still return to the raid den to continue battling after the one-time catch for additional rewards; this is standard for limited Tera Raid events.
The Mightiest Mark currently distinguishes the event capture and is often used to identify distribution or contest Pokémon in Scarlet and Violet.
How this fits into Scarlet and Violet's post-launch support
Tera Raid Battles are part of Pokémon Scarlet and Violet's ongoing online features, and The Pokémon Company has repeatedly used time-limited raids to distribute rare forms and marked Pokémon.
Game Freak continues to support Scarlet and Violet with seasonal and event content that leverages multiplayer raid mechanics on Nintendo Switch.
If you plan to attempt the raid, ensure your game is updated and your internet connection is stable before joining a 7-star Tera Raid.
