Get ready for a battle like no other—Hydreigon, the three-headed terror with a taste for destruction, is descending upon 7-Star Tera Raid Battles in Pokémon Scarlet and Pokémon Violet! But here's where it gets intense: this isn't just any Hydreigon; it’s the one with the Mightiest Mark, a title reserved only for the most fearsome foes. Mark your calendars: this brutal Pokémon will appear at black Tera Raid crystals from Thursday, November 6, 2025, at 4:00 p.m. PST to Sunday, November 9, 2025, at 3:59 p.m. PST, and again from Thursday, November 13, 2025, at 4:00 p.m. PST to Sunday, November 16, 2025, at 3:59 p.m. PST. With its Tera Type set to Poison, this Hydreigon is not just a challenge—it’s a test of your skills and teamwork. And this is the part most people miss: during the second half of the event, Blissey will be appearing more frequently in 5-star Tera Raid Battles, offering a chance to snag various Tera Shards and bonus Exp. Candies. But don’t let that distract you from the main event—Hydreigon is the star here, and it’s not going down without a fight.
To face this mighty opponent, you’ll need to either complete the postgame events or join a raid hosted by someone who has. Here’s the catch: you can only catch this Hydreigon once per save data, but you can still join raids to earn rewards like Exp. Candy, treasures, stat-boosting items, and Poison Tera Shards. But here’s the controversial part: is Hydreigon’s Mightiest Mark truly a mark of honor, or just a warning of its relentless brutality? Let us know your thoughts in the comments!
If you’re new to Tera Raid Battles, here’s how to get started: look for a sparkling pillar of light emanating from a Tera Raid crystal, walk up to it, and interact to begin the battle. To ensure you’re ready for this event, make sure to download the latest Poké Portal News by following these steps:
