Mightiest Mark Returns: Greninja and Delphox Take Over 7-Star Tera Raid Battles
Pokémon Trainers in Pokémon Scarlet and Pokémon Violet are facing a gauntlet of high-stakes challenges as two powerhouse Pokémon return to 7-star Tera Raid Battles. Featuring the prestigious Mightiest Mark, these events offer a rare opportunity to capture exceptionally strong versions of Greninja and Delphox, though they require strategic coordination and post-game progress to conquer.
The Current Challenge: Poison-Tera Type Greninja
Following the conclusion of the Delphox event, the spotlight has shifted to the stealthy Greninja. This powerful Pokémon has returned to black Tera Raid crystals, challenging Trainers with a surprising Poison-Tera Type.
The Greninja event is currently active and will run from Thursday, May 7, 2026, at 5:00 p.m. PDT until Thursday, May 14, 2026, at 4:59 p.m. PDT. Because this Greninja carries the Mightiest Mark, it represents one of the most formidable encounters available in the game, requiring Trainers to work together to avoid a “sticky situation” and secure the catch.
Recent Event Recap: Fairy-Tera Type Delphox
Just prior to the arrival of Greninja, the elegant Delphox made a brief appearance. From April 30 to May 7, 2026, Trainers had the chance to battle a Fairy-Tera Type Delphox at black Tera Raid crystals. While the window to catch this specific Mightiest Mark Delphox has closed, the event highlighted the recurring nature of these high-level raid rotations in the Paldea region.
How to Access 7-Star Tera Raid Battles
Participating in these events isn’t as simple as finding a crystal; there are specific technical and gameplay requirements to ensure the Pokémon appear.
1. Update Your Poké Portal News
To trigger the appearance of event Pokémon, you must download the latest Poké Portal News. Follow these steps in-game:
- Open the X menu and select Poké Portal.
- Select Mystery Gift.
- Select Check Poké Portal News.
2. Meet Gameplay Requirements
Due to the extreme difficulty of 7-star raids, there are entry restrictions. To challenge a Mightiest Mark Pokémon, you must either:
- Complete the postgame events that follow the main story of Pokémon Scarlet or Pokémon Violet.
- Join a 7-star Tera Raid Battle hosted by another Trainer who has already completed these postgame events.
Rewards and Limitations
While the primary goal for most Trainers is to catch the featured Pokémon, these raids provide significant value even after the capture is complete. Note that the special Mightiest Mark Pokémon can be caught only once per save data.
However, Trainers can continue to participate in the raids to earn the following rewards:
- Exp. Candy: Large quantities for rapid leveling of other Pokémon.
- Stat-Improving Items: Essential tools for optimizing Pokémon performance.
- Tera Shards: Poison Tera Shards (during the Greninja event) or Fairy Tera Shards (during the Delphox event) for changing a Pokémon’s Tera Type.
- Treasures: Various items that can be sold at Pokémon Centers for currency.
