If you are searching for 10th anniversary Mewtwo Pokémon GO, the answer is yes: Mewtwo was a major part of Pokémon GO’s 10th-anniversary celebrations in 2026. Mega Mewtwo X and Mega Mewtwo Y made their Pokémon GO debut during Pokémon GO Fest 2026: Global on July 11 and 12.
10th Anniversary Mewtwo in Pokémon GO: Is Mewtwo Returning in 2026?
During the event, Trainers could battle Mega Mewtwo X and Mega Mewtwo Y in Super Mega Raids and then catch Mewtwo. Those Mewtwo encounters also had a special bonus: every Mewtwo caught from the Super Mega Raids had at least one Mega Level unlocked, allowing it to be Mega Evolved into the form battled without the initial Mega Energy cost.
However, if you are asking whether another Mewtwo return is currently scheduled after the 10th-anniversary event, there is no new Mewtwo raid date confirmed in the official event information available at the time of writing.
What Happened With Mewtwo During the Pokémon GO 10th Anniversary?
Mewtwo became one of the biggest highlights of Pokémon GO’s 10th-anniversary year because its two Mega Evolutions finally arrived in the game.
Mega Mewtwo X appeared in Super Mega Raids on Saturday during Pokémon GO Fest 2026: Global, while Mega Mewtwo Y appeared on Sunday.
The global event was held on July 11 and 12, 2026, from 10:00 a.m. to 7:00 p.m. local time each day.
Unlike some previous Pokémon GO Fest events, the 2026 global celebration was free for all Trainers. Mewtwo was also available through the Super Mega Raid encounters, making the anniversary especially important for players who had been waiting for its Mega Evolutions.
Is Mewtwo Coming Back to Pokémon GO in 2026?
Mewtwo already returned to Pokémon GO in 2026 as part of Pokémon GO Fest 2026: Global.
During the event, players could battle Mega Mewtwo X and Mega Mewtwo Y in Super Mega Raids and receive encounters with Mewtwo after defeating them.
If your question is whether Mewtwo will appear in another set of raids later in 2026, that depends on future event announcements. Pokémon GO does not guarantee that a Legendary Pokémon will immediately return after an event, and a future Mewtwo appearance should not be assumed until Niantic announces it.
For now, the important distinction is:
- Did Mewtwo return in 2026? Yes.
- Did Mega Mewtwo debut in 2026? Yes, Mega Mewtwo X and Y debuted during GO Fest.
- Is another Mewtwo raid currently confirmed? No new return should be treated as confirmed without an official announcement.
Is Mega Mewtwo Coming for GO Fest 2026?
Yes. In fact, Mega Mewtwo X and Mega Mewtwo Y were the featured Mega Mewtwo additions to GO Fest 2026.
Players could encounter the two forms through Super Mega Raids. Mewtwo caught from those raids had at least the first Mega Level unlocked, giving players an easier path toward using Mega Mewtwo.
There was also a branching Timed Research option during the global event that allowed Trainers to choose between Mega Mewtwo X and Mega Mewtwo Y-related rewards.
What Is the Difference Between Mega Mewtwo X and Mega Mewtwo Y?
Mewtwo has two Mega Evolutions in Pokémon GO: Mega Mewtwo X and Mega Mewtwo Y.
They are not simply two appearances of the same form. They have different typings and can be useful for different types of battles.
| Form | Type | Main use |
|---|---|---|
| Mega Mewtwo X | Psychic / Fighting | Powerful Psychic and Fighting-type attacker |
| Mega Mewtwo Y | Psychic | Powerful Psychic-type attacker |
This makes it worthwhile for serious players to keep more than one strong Mewtwo if they have the resources to build them.
Can You Still Get Mewtwo in Pokémon GO?
Whether you can currently obtain a new Mewtwo depends on the active Pokémon GO events and raid rotation.
The 10th-anniversary GO Fest gave players a major opportunity to catch Mewtwo through Mega Mewtwo X and Y Super Mega Raids, but that event has already ended.
If Mewtwo is not currently appearing in raids, players who missed the event will need to wait for another official opportunity, such as a future raid rotation, event, research encounter or other officially announced distribution method.
It is also worth remembering that having an older Mewtwo does not make it obsolete. Pokémon GO’s 2026 Mega Evolution update allows previously caught Mewtwo to Mega Evolve as long as the required Mega Energy and other conditions are met.
Is the Mewtwo From the 10th Anniversary a Hundo?
No. A Mewtwo caught during the 10th-anniversary event was not automatically a hundo.
“Hundo” is the community term for a Pokémon with perfect 15 Attack, 15 Defense and 15 HP IVs.
Because raid encounters can produce different IV combinations, you had to check the individual Mewtwo you caught to determine whether it was a 100% IV Pokémon.
The special 10th-anniversary background or Mega Level bonus does not automatically mean the Mewtwo has perfect IVs.
What Is the 100% IV Mewtwo CP in Pokémon GO?
If you caught a standard Mewtwo from a Level 20 raid encounter, a perfect 100% IV Mewtwo has 2387 CP.
When Mewtwo is weather boosted and therefore caught at Level 25, a perfect 100% IV encounter has 2984 CP.
| Mewtwo encounter | Hundo CP |
|---|---|
| Standard raid, Level 20 | 2387 CP |
| Weather-boosted raid, Level 25 | 2984 CP |
| Research encounter, Level 15 | 1791 CP |
If your raid Mewtwo has one of these perfect CP values, check its appraisal to confirm the IVs before transferring or trading it.
What Is the Best Mewtwo Moveset in Pokémon GO?
For a strong Psychic-type Mewtwo, one of the best combinations is Psycho Cut + Psystrike.
Psystrike is Mewtwo’s signature Charged Attack and is especially valuable for Psychic-type damage. However, Psystrike is a legacy move, so getting it may require an Elite Charged TM unless the Mewtwo was caught during an event where it was available.
The best moves can also depend on what you want to use Mewtwo for.
- Psychic attacker: Psycho Cut + Psystrike is a strong choice.
- Mega Mewtwo Y: Psychic-type moves are particularly useful for its role as a Psychic attacker.
- Mega Mewtwo X: It can also take advantage of its Fighting typing and moves such as Counter and Focus Blast depending on how you intend to use it.
- Coverage: Mewtwo has other Charged Attacks that can be useful against different opponents.
There is therefore no single moveset that is perfect for every Mewtwo. Your choice should depend on whether you are building it for raids, Gyms, Team GO Rocket battles or PvP.
What Made the 10th Anniversary Mewtwo Special?
The biggest difference was not simply the opportunity to catch another Mewtwo. The 2026 anniversary introduced Mewtwo’s Mega Evolutions to Pokémon GO for the first time.
Mewtwo caught from the Super Mega Raids during GO Fest Global received at least one Mega Level unlocked. This meant players could Mega Evolve the Pokémon into the form associated with the raid without paying the initial Mega Energy cost.
Some Mewtwo encounters could also have a special 10th-anniversary-themed background.
That makes certain Mewtwo caught during the event particularly interesting to collectors, especially those with strong IVs, a special background or a favourable moveset.
Will Mewtwo Ever Return to Pokémon GO?
It is reasonable to expect Mewtwo to return at some point, but future appearances are not guaranteed until officially announced.
Legendary Pokémon can return through new raid rotations and special events, sometimes with new bonuses, featured moves, backgrounds or other mechanics.
Mewtwo’s importance in Pokémon GO also increased significantly with the arrival of Mega Mewtwo X and Y, so players should watch official Pokémon GO event announcements for future opportunities.
If you missed the 10th-anniversary event, there is no need to assume that your chance to obtain Mewtwo is permanently gone. The important thing is to wait for an official future availability announcement rather than relying on rumours.
Mewtwo Raids in 2026: What Players Should Know
The 2026 Mewtwo raid story was closely connected to GO Fest rather than a normal recurring Legendary raid rotation.
During GO Fest Global, Mega Mewtwo X appeared on Saturday and Mega Mewtwo Y on Sunday in Super Mega Raids.
Players who wanted to build both forms therefore had a reason to participate on both days.
However, the event calendar changes regularly. If you are checking for Mewtwo raids 2026, always look at the latest official Pokémon GO event announcements rather than relying on an old raid schedule.
What Should You Do With a Strong Mewtwo?
If you caught a high-IV Mewtwo during the anniversary event, it is worth checking its appraisal before deciding what to do with it.
A strong Mewtwo can be valuable for several reasons:
- It can be used as a powerful Psychic-type attacker.
- It can Mega Evolve into Mega Mewtwo X or Mega Mewtwo Y.
- High-IV specimens are useful for players who care about maximizing battle performance.
- Special-background Mewtwo can have additional collector value.
- Mewtwo with legacy attacks such as Psystrike can be particularly useful.
Before spending large amounts of Stardust, Candy or Candy XL, decide how you want to use the Pokémon. You may not need to power up every Mewtwo you catch.

Bottom Line
The 10th anniversary Mewtwo Pokémon GO story was a major one for Trainers in 2026. Mewtwo returned during GO Fest Global, and more importantly, Mega Mewtwo X and Mega Mewtwo Y made their Pokémon GO debut.
If you caught Mewtwo during the event, check its IVs, CP, moves and background before deciding whether to power it up or Mega Evolve it. A perfect raid Mewtwo has 2387 CP at Level 20 or 2984 CP when weather boosted.
If you missed the anniversary event, keep an eye on official Pokémon GO announcements for the next confirmed Mewtwo opportunity. Until then, avoid treating rumours about Mewtwo raids 2026 or another Mewtwo return as confirmed information.
