Hydreigon Poison Tera Raid Event Announced for Pokémon Scarlet and Violet on Nintendo Switch

Pokémon Scarlet and Pokémon Violet continue to engage Nintendo Switch players with dynamic post-launch content, and the latest update brings a new Tera Raid Battle spotlight featuring Hydreigon.

The popular Dragon- and Dark-type Pokémon will star in an exclusive event where it will sport the Poison Tera Type and the coveted Mightiest Mark, offering fans a challenging new cooperative raid to conquer. This Hydreigon Tera Raid Battle will be available in the games' high-difficulty 7-Star Raids.

During the event, trainers can partner with up to three others online to defeat and, if successful, capture Hydreigon.

Notably, each save file allows for only one capture of this special Hydreigon, making the event particularly valuable for completionists and competitive players alike. The event is scheduled to run twice: the first period begins on November 7 and concludes on November 9.

Players who miss the initial window will have a second opportunity, as the event returns from November 14 through November 16.

These dates give fans two chances to engage with one of the toughest Tera Raid Battle experiences currently available in Pokémon Scarlet and Violet. Tera Raid Battles stand out for their cooperative gameplay—up to four trainers work together to take down a singular powerful Pokémon within a time limit.

The featured Pokémon will often possess a rare Tera Type, providing both strategic intrigue and sought-after rewards for participants.

According to official sources, accessing the latest Tera Raid events is straightforward: if your Nintendo Switch is connected to the internet, the most recent Poké Portal News will automatically download, ensuring you have all the details needed to join the raid.

For those who wish to update manually, simply select Poké Portal from the in-game X menu, choose Mystery Gift, and then Check Poké Portal News. Both Pokémon Scarlet and Pokémon Violet are available now on Nintendo Switch, and the games continue to receive regular updates with new events and features to keep the experience fresh for devoted trainers.
