Metagross Mightiest Mark 7-Star Tera Raid Returns in Pokémon Scarlet and Violet

Metagross is returning to Pokémon Scarlet and Pokémon Violet as a 7-star Tera Raid Battle opponent, giving players another opportunity to face—and, if eligible, catch—the powerful Steel–Tera Type Pokémon with the Mightiest Mark.

The event runs from Thursday, October 15, 2026, at 5:00 p.m. PDT until Thursday, October 22, 2026, at 4:59 p.m. PDT. During that window, the event Metagross can appear at black Tera Raid crystals in the Paldea region. It is built as a high-level cooperative challenge rather than an ordinary overworld encounter, so preparation and access requirements matter as much as locating the crystal.

Event timing and the key details

Game: Pokémon Scarlet and Pokémon Violet on Nintendo Switch
Raid tier: 7-star Tera Raid Battle
Featured Pokémon: Metagross
Tera Type: Steel
Availability: October 15, 2026, at 5:00 p.m. PDT through October 22, 2026, at 4:59 p.m. PDT
Special distinction: Mightiest Mark
Capture limit: One catch per save data

A Tera Type is the type a Pokémon uses while Terastallized in these battles. In this case, Steel is especially important: players should base their raid planning on the event Metagross’s Steel Tera Type, not simply on assumptions drawn from Metagross’s usual typing. The Tera Type determines the raid boss’s transformed defensive profile and is the central detail players need when considering what to bring.

The Mightiest Mark is the identifier attached to these special event raid Pokémon. It distinguishes this Metagross from a standard capture and signals the significance of the 7-star challenge. The mark does not change the one-per-save rule: a player who catches it during a prior appearance cannot catch another copy on that same save, even though they can still join later raids.

Where to find the Metagross raid

Event Metagross appears at black Tera Raid crystals. Tera Raid crystals are marked in the world by a sparkling pillar of light; interacting with one starts a Tera Raid Battle. Not every visible raid crystal will necessarily be the featured event encounter, so the black crystals are the important target for this specific 7-star battle.

Players will also need current Poké Portal News data for the event to populate correctly. The update process is handled from within the game:

Open the X menu and choose Poké Portal.
Select Mystery Gift.
Choose Check Poké Portal News.

That short check is a practical first step before setting out to search. A player can spend plenty of time examining raid crystals, but without the latest Poké Portal News, the featured-event data may not be present. Updating first makes the hunt for the black crystal meaningful rather than a tour of Paldea’s less relevant raid battles.

Who can challenge the 7-star raid?

There are two routes into this Metagross battle. Players can enter directly after completing the postgame events that follow the main story. Alternatively, players who have not met that progression requirement can join a 7-star raid hosted by another Trainer who has completed those postgame events.

That distinction makes hosting access and participation access different things. A player who has finished the required postgame content can find and host the event raid. A player who has not can still take part through a qualifying host. For groups of friends, that means the whole party does not necessarily need identical story progression before attempting the encounter together.

The event description explicitly encourages players to work with friends, which fits the structure of Tera Raid Battles: the featured Metagross is intended as a strong opponent, and a coordinated group can make better use of its shared opportunity. Still, no specific recommended Pokémon, moves, items, turns, or strategy have been established here. Players should be wary of treating unverified build claims as official event requirements.

One Metagross catch, but repeat rewards remain worthwhile

The event Metagross can be caught only once per save data. That restriction is easy to misread as a reason to stop once a capture is secured, but the raid remains useful after that first catch. Players may continue to participate in battles against the event Metagross to earn the associated drops.

The listed rewards include:

Exp. Candy, used to level up Pokémon.
Treasures, which can be sold at Pokémon Centers.
Stat-improving items, useful for developing Pokémon.
Steel Tera Shards, used to change a Pokémon’s Tera Type.

That reward structure gives repeat runs two clear purposes. First, Exp. Candy provides a direct way to build up other members of a player’s roster. Second, Steel Tera Shards have a more specialized use: they can help change a Pokémon’s Tera Type to Steel. For players interested in adjusting a Pokémon’s Terastallization identity rather than simply gaining levels or selling loot, those shards are the event-specific material worth watching.

In other words, the capture limit applies to the special Metagross itself, not to every benefit attached to the battle. A player who already owns this Mightiest Mark Metagross can still contribute to a friend’s run, seek more rewards, or return for Steel Tera Shards. That makes the rerun relevant to both first-time challengers and veterans whose single capture is already complete.

What players should do before the deadline

The event window lasts one week, closing on October 22 at 4:59 p.m. PDT. Players who want the special Metagross should not leave the essential setup until the last moment. The straightforward checklist is to update Poké Portal News, confirm whether the save has access to 7-star raid hosting, and arrange to join a qualified host if it does not.

Launch Pokémon Scarlet or Pokémon Violet.
Use Poké Portal’s Mystery Gift menu to check Poké Portal News.
Look for a black Tera Raid crystal if the save has completed the required postgame events.
If it has not, join a raid hosted by a Trainer who has completed them.
Catch Metagross if this save has not already claimed its one capture.
Return to the battle after catching it if Exp. Candy, sellable treasures, stat items, or Steel Tera Shards are useful.

Why the Steel Tera Type is the detail to plan around

“Steel–Tera Type Metagross” is more than a label for the event. Tera Raids are built around Terastallization, so the Steel designation tells players what transformed type the boss will use in the battle. That is the relevant starting point for team selection and coordination.

It is also why broad advice based only on Metagross’s standard identity can be incomplete. The event supplies one confirmed tactical fact—its Steel Tera Type—but does not provide a full official move list, behavior pattern, or prescribed counter roster. The sensible approach is to use the confirmed type as the foundation, then account for the fact that this is a 7-star encounter with a Mightiest Mark, where raw type matchup alone may not settle the battle.

For players who enjoy competitive games with a very different kind of team coordination, the wider game world has no shortage of unusual high-stakes stories, including a Dota 2 match that reportedly helped verify a player’s identity. Metagross’s return is a much more conventional reason to gather teammates: a limited-time raid, a one-time catch, and useful repeat rewards.

A limited-time return with value beyond the first clear

This raid’s central appeal is simple: it offers another chance at a Steel–Tera Type Metagross carrying the Mightiest Mark. For eligible players who missed the Pokémon before, the October 15–22 event period is the opportunity to add it to their save. For players who caught it previously, the return still provides a repeatable source of leveling materials, sellable treasures, stat-focused items, and Steel Tera Shards.

Just remember the important dividing line. Catch eligibility is limited to one Metagross per save data; raid participation and reward collection are not described as ending after that catch. Update Poké Portal News, find or join the appropriate black-crystal battle, and make the attempt before the event closes.
