The Mightiest Mark isn't just flavor text—it's a warning.
Once more, a formidable creature emerges from the digital wilds to test those who have proven themselves worthy of the challenge. From April 3rd through April 9th, 2026, Pokémon Scarlet and Violet trainers who have walked the full arc of their journey will find Serperior — bearing the Mightiest Mark — waiting at black Tera Raid crystals, offering not just rare rewards, but a measure of one's readiness. It is the oldest of stories: the world placing a worthy obstacle before those who have earned the right to face it.
- A 7-star Serperior bearing the Mightiest Mark has appeared, and its Grass Tera Type demands careful, deliberate team-building from any trainer bold enough to approach.
- The encounter is gated behind story completion, creating a sharp divide between those prepared for the challenge and those still finding their footing.
- Trainers can only catch this special Serperior once per save file, raising the stakes of every attempt and making each encounter feel genuinely consequential.
- Repeat battles remain richly rewarding — Exp. Candy, stat-boosting items, and Grass Tera Shards keep even veteran trainers returning long after the catch is secured.
- Cooperation is the recommended path forward, with friends able to join forces locally or online to coordinate strategy against this unforgiving opponent.
- The window is narrow — just one week — and access requires downloading the latest Poké Portal News before the black crystals will appear in the world.
Serperior has returned to Pokémon Scarlet and Violet, and it arrives with a clear message. From April 3rd at midnight UTC through April 9th at 11:59 p.m., the Regal Pokémon waits at black Tera Raid crystals across the game, marked with the Mightiest Mark and carrying a Grass Tera Type that demands thoughtful preparation from any trainer who steps forward.
This is not an encounter for newcomers. Only trainers who have completed the main story and its postgame events can host the raid themselves, though friends who haven't yet reached that milestone can still participate in someone else's session. The barrier is intentional — Serperior at this level is genuinely dangerous, and the game expects you to arrive ready.
Catching this Serperior is a one-time opportunity per save file, but the raids themselves can be repeated as often as a trainer likes. The rewards justify the effort: meaningful quantities of Exp. Candy, individual stat-boosting items, sellable treasures, and Grass Tera Shards for retyping your own Pokémon. Even trainers who have already secured their catch have good reason to keep battling.
Accessing the event requires downloading the latest Poké Portal News through the game's X menu — a quick process through Mystery Gift and Check Poké Portal News. Once done, the black crystals appear in the world, each one announcing itself with a sparkling pillar of light. Solo attempts are possible, but cooperation with friends, locally or online, is the wiser path. For one week, the Regal Pokémon stands as the clearest test of what a postgame trainer is made of.
Serperior is back, and it's brought reinforcements. Starting Friday, April 3rd at midnight UTC and running through the following Thursday at 11:59 p.m., players of Pokémon Scarlet and Violet will find the Regal Pokémon waiting at black Tera Raid crystals across their games. This particular Serperior carries the Mightiest Mark—a designation that signals serious trouble. Its Tera Type is Grass, which means trainers will need to think carefully about their team composition before stepping up to challenge it.
The encounter is not for everyone. To even attempt this 7-star Tera Raid, you must have finished the main story and completed the postgame events that follow. If you haven't reached that point yet, you can still join raids hosted by friends who have cleared those milestones. The barrier to entry exists for a reason: this Serperior is genuinely formidable, and the game wants you prepared before you face it.
Catching this version of Serperior is a one-time-only proposition per save file. Once you've claimed it, that slot is filled. But the raids themselves remain open to repeat challenges, and there's good reason to keep coming back. Each battle yields substantial rewards—Exp. Candy in meaningful quantities for leveling up your team, items that boost your Pokémon's individual stats, treasures you can sell at Pokémon Centers for cash, and Grass Tera Shards for retyping your own Pokémon. The loot economy is generous enough that even trainers who've already caught their Serperior will find value in grinding out additional encounters.
To access the event, you'll need to have downloaded the latest Poké Portal News through your game's X menu. The process is straightforward: open Poké Portal, select Mystery Gift, then Check Poké Portal News. Once that's done, the black Tera Raid crystals hosting Serperior will appear in your world. When you spot one—they announce themselves with a sparkling pillar of light—you can walk up and interact with it to initiate the battle.
The game encourages cooperation. You can tackle this raid solo if you're confident, but the recommended approach is to team up with friends, either locally or online. Serperior's intensity demands coordination and smart strategy. The Mightiest Mark isn't just flavor text; it's a warning. This is the kind of encounter that separates casual players from those willing to optimize their teams and coordinate tactics. For the next week, trainers who've earned the right to face postgame content have a clear objective: take down the Regal Pokémon, claim the rewards, and see if they can do it again.

The Hearth Conversation Another angle on the story
Why does this Serperior matter more than any other raid encounter?
The Mightiest Mark signals it's a genuine test. It's not just a rare Pokémon—it's a benchmark for how far you've come in the game.
So you have to finish the entire story before you can even try it?
Yes. The postgame events are a gate. It keeps the difficulty meaningful and ensures trainers have the tools to compete.
