During a press conference in Tokyo, Niantic confirmed that Mewtwo will be part of Pokémon GO Fest 2026. Key artwork shown at the event prominently features the iconic Psychic-type floating above a mix of Kanto Pokémon, effectively ending speculation about its return.

According to coverage from Japanese outlet rocketnews24go, a Niantic spokesperson teased, “I can’t say anything specific, but look forward to the Pokémon featured in the key visual. Especially Mewtwo… I think it’ll be heart-pounding excitement for people who’ve been participating in GO Fest since the early days.”

Mewtwo was last widely available in standard raids back in July 2022. Its Shadow form did appear briefly over a weekend in March 2024, but many players have been waiting for a proper return ever since. For newer trainers, this will be the first realistic opportunity to add Mewtwo to their Pokédex.

Pokémon GO Fest 2026 Dates And Locations

Pokémon GO Fest 2026 will take place across three in-person cities before culminating in a global event.

The schedule is as follows:

Tokyo, Odaiba area: May 29 to June 1Chicago, Grant Park: June 5 to 7Copenhagen, Fælledparken: June 12 to 14

The Tokyo venue will span Odaiba Seaside Park, Symbol Promenade Park, and Shiokaze Park, forming a large interconnected play area. Attendees can choose between morning sessions from 10:00am to 2:00pm or afternoon sessions from 4:00pm to 8:00pm, with a two-hour transition window in between.

Citywide gameplay will begin several days before each in-person event, allowing both locals and travelling trainers extra time to explore and complete event tasks.

While Mewtwo is featured in Tokyo’s artwork, it is widely expected to be available globally during GO Fest 2026, rather than locked to a single location.

Exclusive Legendary Birds For Each City

In addition to Mewtwo’s return, each host city will feature an exclusive Legendary Kanto Bird encounter:

Articuno in TokyoZapdos in ChicagoMoltres in Copenhagen

These city-specific exclusives add another layer of incentive for in-person attendance. However, the broader focus of the event clearly centres on Mewtwo’s global comeback.

Mega Mewtwo And New Evolutions On The Horizon?

The timing of Mewtwo’s return has also reignited long-running speculation about Mega Evolutions.

Mega Mewtwo X and Mega Mewtwo Y remain notably absent from Pokémon GO, despite many other Mega Evolutions already being introduced. With Mega Malamar and Mega Victreebel from Pokémon Legends: Z-A scheduled to arrive soon, fans are questioning whether GO Fest 2026 could finally be the moment Niantic rolls out Mega Mewtwo.

There has been no official confirmation yet, but the anniversary year context makes it feel like a natural opportunity.

Zeraora Hints Spark Mythical Debut Speculation

Beyond Mewtwo, Pokémon GO Fest 2026 branding has sparked speculation about the debut of the Mythical Pokémon Zeraora.

Observers have pointed to subtle blue lightning bolt motifs in the event’s logo, which align closely with Zeraora’s Electric typing and design themes. Zeraora recently received a new Mega Evolution in Pokémon Legends: Z-A, adding further weight to the theory that it could make its Pokémon GO debut this year.

As with Mega Mewtwo, Niantic has not officially confirmed Zeraora’s arrival, but the hints have not gone unnoticed within the community.

A Major Milestone Year For Pokémon GO

This year represents a rare double celebration. Pokémon GO turns 10, while the Pokémon franchise itself celebrates its 30th anniversary.

Bringing back Mewtwo, arguably one of the most recognisable Legendary Pokémon ever created, feels like a deliberate move to anchor those celebrations in nostalgia while still pushing forward with new content.

More announcements are expected on Pokémon Day, February 27, when The Pokémon Company traditionally shares updates on upcoming games and expansions. With Generation 10 rumours circulating and Pokémon Legends: Z-A content already rolling out, GO Fest 2026 may only be part of a much bigger year for the franchise.

For now, though, one thing is certain. Mewtwo is finally coming back to Pokémon GO, and for many trainers, that alone is reason enough to start preparing raid teams for the summer.
