The 7 Star Hydreigon Tera Raid returns to Pokémon Scarlet and Violet from October 30 to November 5, 2026, bringing back Hydreigon with the Mightiest Mark and a Poison Tera Type. This is one of the returning powerhouse raids in the new weekly run of black crystal events, so players who missed the original encounter have another chance to clear it and catch the event Pokémon.
Because the 7 Star Hydreigon Tera Raid is a rerun of an established Mightiest Mark encounter, there is already a clear picture of the moves, scripted actions and counters that matter. The important catch rule also carries over: this event Hydreigon can only be caught once per save data, and anyone who caught the same Unrivaled Hydreigon during its previous event can still battle it for rewards but cannot catch a second one.
7 Star Hydreigon Tera Raid schedule and key details

The 7 Star Hydreigon Tera Raid is a level 100 black crystal battle in Paldea. Hydreigon has the Levitate Ability, a Modest Nature and the Poison Tera Type, which is the typing you need to plan your damage around rather than simply countering Hydreigon’s normal species typing. The established encounter uses an unusually large raid HP multiplier of about 25x, so a build that can survive and scale is more useful than a glass cannon that only looks strong for one turn.

Hydreigon moveset and raid mechanics
The returning Hydreigon encounter uses Tera Blast, Dark Pulse, Dragon Pulse, Earth Power as its regular move set. It can also use scripted actions including Snarl, Nasty Plot, Dragon Dance, which means the 7 Star Hydreigon Tera Raid is not a fight where type advantage alone is enough. You need to account for the extra actions, the shield and the points where the boss can reset stat changes.
The main danger is the way those scripted actions can change the pace without costing Hydreigon the same kind of turn a player would spend. A good solo build therefore needs a reliable damage plan, a way to control the most dangerous boosts or attacks, and enough recovery to survive after the shield appears. The 7 Star Hydreigon Tera Raid rewards patient setup much more than throwing a random super effective attacker at the crystal.
Best counter for 7 Star Hydreigon Tera Raid
A strong solo answer for the 7 Star Hydreigon Tera Raid is Malamar. Malamar turns one of Hydreigon’s strengths into a liability. Skill Swap can hand Contrary to Hydreigon, so its scripted Nasty Plot no longer gives it the special attack jump it expects. The same move also removes Levitate, which simplifies the ability situation, while Calm Mind gives Malamar the special bulk and Stored Power scaling needed for a long solo attempt. The set below is designed around the established raid rather than ordinary competitive battling, so the EVs, held item and support moves are all there for raid consistency.
| Build slot | Malamar setup |
|---|---|
| Tera Type | Psychic |
| Nature | Modest |
| Ability | Contrary |
| Held item | Shell Bell |
| EVs | 252 HP / 4 Sp. Atk / 252 Sp. Def |
| Moves | Skill Swap, Calm Mind, Rest, Stored Power |
For the 7 Star Hydreigon Tera Raid, level the counter to 100 and make sure the important moves and EVs are in place before entering the raid. A half-finished build can still look fine in the opening minute, then collapse once the shield, resets and scripted actions begin. That is especially frustrating in a timed raid because repeated knockouts remove time as well as momentum.
How to beat 7 Star Hydreigon Tera Raid solo
The safest approach to the 7 Star Hydreigon Tera Raid is to treat the opening turns as control and setup rather than a damage race. Skill Swap is the important opening move because the entire plan becomes safer once Hydreigon has Contrary. Build with Calm Mind while watching your health and use Rest rather than gambling on a knockout when the raid is still far from finished. Stored Power becomes stronger as your boosts accumulate, so the damage curve improves as the setup develops. Psychic Tera then gives the attack the right typing into Poison Tera Hydreigon, while Shell Bell adds recovery once Stored Power starts hitting hard. Keep an eye on the raid text so you know when stat changes have been removed, because blindly repeating the previous turn after a reset can waste the advantage you just built.
Once the counter is stable, the goal is to keep enough offensive pressure that the timer continues moving in your favour without giving away avoidable knockouts. Terastallizing at the right point is important because it improves damage against the Poison Tera target and lets you keep attacking into the shield. If the 7 Star Hydreigon Tera Raid is consistently knocking you out before that stage, fix the defensive side of the build first rather than adding more raw damage.
Other counters for the Hydreigon 7-star raid
There is more than one workable answer to the 7 Star Hydreigon Tera Raid, especially in multiplayer where one Pokémon can focus on support while another deals damage. These alternatives are worth considering if you already have them trained or if the recommended solo build is awkward for your save.
- Magearna can pressure the Poison Tera target with strong special offense and useful bulk.
- Vaporeon can play a slower support route in groups that already have a dedicated damage dealer.
Whichever route you choose, build for the actual Poison Tera Type and the established moveset rather than the usual weaknesses of wild Hydreigon. That distinction is what catches players out in 7-star raids, where the Tera Type determines the boss’s defensive weakness while its original move coverage can still punish an apparently obvious counter.
How to find the 7 Star Hydreigon Tera Raid
To make the 7 Star Hydreigon Tera Raid appear, connect Pokémon Scarlet or Violet to the internet and refresh the latest Poké Portal News by opening Poké Portal > Mystery Gift > Check Poké Portal News. Players who have completed the required postgame progression can find the event at black Tera Raid crystals in Paldea. If you have not unlocked black crystals on your own map yet, you can still join an eligible host through multiplayer.
The official Pokémon event announcement confirms that this returning series begins with Dragonite and that the raids are held in succession. The 7 Star Hydreigon Tera Raid is only active during its listed weekly window, so make sure your Poké Portal News is current before assuming a missing crystal is a bug.
Can you catch Hydreigon again?
You cannot catch a second copy of this same Unrivaled Hydreigon if you already caught it during the previous event. The catch limit applies to the returning 7 Star Hydreigon Tera Raid as the same special event Pokémon, not as a fresh one-per-rerun allowance. You can still defeat the raid as many times as the event permits and collect its item rewards, which gives returning players a reason to farm it even when the catch itself is unavailable.
Is the 7 Star Hydreigon Tera Raid worth farming?
Yes, the 7 Star Hydreigon Tera Raid can still be useful after you have used your one catch. Seven-star black crystal raids are valuable sources of high-level reward items, including experience items, Tera Shards and chances at rarer materials, while the first clear of an event raid can also include fixed rewards. Farming is much quicker once you have a stable counter because you avoid losing time to repeated failed attempts.
If your only goal is the Mightiest Mark Hydreigon, one clear is enough. If you are building several raid Pokémon for the rest of this ten-week run, repeated clears can help fund the next counter with experience, bottle caps, ability items and Tera resources. That makes the 7 Star Hydreigon Tera Raid part of a useful preparation loop rather than an isolated weekly boss.
