How to Beat 7-Star Poison Tera Hydreigon in Pokémon Scarlet & Violet | Mightiest Mark Event Guide (2025)

Get ready for an epic battle! The fearsome Hydreigon, a three-headed terror, is descending upon the Pokémon Scarlet and Violet games, and it's packing a powerful punch with its Mightiest Mark.

But here's the challenge: From November 6th to 9th and again from November 13th to 16th, 2025, this Brutal Pokémon will be available in 7-star Tera Raid Battles, ready to take on all challengers. And it's not coming alone!

During the event, Hydreigon will boast the Poison Tera Type, making it an even more formidable opponent. But don't let that intimidate you—gather your friends and unite your forces to conquer this mighty creature. Remember, teamwork makes the dream work!

And here's where it gets exciting: In the latter part of the event, Blissey will be making more frequent appearances in 5-star Tera Raid Battles, offering a variety of Tera Types to test your skills. Overcoming these Blissey battles will grant you a treasure trove of rewards, including Tera Shards and bonus Exp. Candies.

To engage in these thrilling Tera Raid Battles, keep an eye out for sparkling pillars of light emanating from Tera Raid crystals. But there's a catch! To encounter the featured Tera Pokémon, you'll need to ensure you've downloaded the latest Poké Portal News. Simply navigate to the Poké Portal in the X menu, select Mystery Gift, and then choose Check Poké Portal News.

A word of caution: To challenge the Poison-Tera Type Hydreigon with the Mightiest Mark, you'll need to either complete the postgame events or join a 7-star Tera Raid Battle hosted by a Trainer who has done so. This unique Hydreigon can only be caught once per save data, but you can still battle it for other rewards even if you've already caught it. These rewards include Exp. Candy for leveling up your Pokémon, sellable treasures, stat-boosting items, and Poison Tera Shards.
