The Hydreigon appearing during this event has Poison as its Tera Type. Be prepared—this Pokémon is a formidable foe, and it’s got the Mightiest Mark to prove it! Work together with your friends to topple this powerful Tera Pokémon!

During the latter half of this event—from Friday, November 14, 2025, at 00:00 UTC to Sunday, November 16, 2025, at 23:59 UTC—Blissey will be appearing more frequently in 5-star Tera Raid Battles. These Blissey will have various Tera Types, so prepare wisely before challenging them! Defeating Blissey will yield some delightful rewards, such as various Tera Shards and bonus Exp. Candies.

This special Hydreigon can be caught only once per save data. If you caught this Hydreigon previously during a Tera Raid Battle event, you cannot catch it again. You can still participate in Tera Raid Battles against this Hydreigon to obtain other rewards if you’ve already caught it.
