New leaks surrounding Pokemon GO’s upcoming GO Fest 2026 celebrations suggest that Mega Mewtwo X and Mega Mewtwo Y are finally on the way, and the legendary Psychic-type duo may completely reshape the game’s current power rankings.
According to the latest information circulating online, both Mega Evolutions are planned for release during GO Fest 2026 through a brand-new activity called Super Mega Raids. Players attending the live GO Fest events will reportedly gain early access before the forms become more widely available later during the global celebration period.
If the leaks prove accurate, Mega Mewtwo could become one of the most demanding but also most powerful Mega Evolutions ever added to Pokemon GO.
Mega Mewtwo Requires a Massive 7,500 Mega Energy
One of the biggest talking points surrounding the leak is the reported Mega Energy requirement. Both Mega Mewtwo X and Mega Mewtwo Y are said to require an enormous 7,500 Mega Energy for their first transformation.
That number is significantly higher than existing Mega Evolutions currently available in Pokemon GO, instantly making Mega Mewtwo one of the most expensive forms to unlock.
However, there is reportedly a major bonus tied to GO Fest raids. Trainers who catch Mewtwo directly from Mega Raids during the event are expected to receive versions that already have their first Mega Evolution level unlocked. This could dramatically reduce the grind and may push players to prioritize catching new event-exclusive Mewtwos instead of relying on older ones already sitting in storage.
For many players, this could turn GO Fest 2026 into one of the most important events the game has hosted in years.
Mega Mewtwo X and Y Stats Leak Online
The leaked stat details also show just how absurdly strong these forms could become.
Mega Mewtwo X reportedly features:
- Attack: 339
- Defense: 215
- Stamina: 228
- Maximum CP: 6,910
Mega Mewtwo Y reportedly goes even further:
- Attack: 413
- Defense: 223
- Stamina: 228
- Maximum CP: 7,267
If these values remain unchanged at launch, Mega Mewtwo Y would become the highest-CP Mega Pokemon currently available in Pokemon GO. The only known Pokemon rumored to potentially surpass it would be Eternatus in a future release.
That level of power could heavily impact raids, Master League discussions, and future balancing conversations within the Pokemon GO community.
Pokemon GO Is Changing How Dual Mega Evolutions Work
The leaks also align with recent in-game changes that appear to prepare Pokemon GO for more split-form Mega Evolutions moving forward.
A recent update reportedly changed how Mega Charizard Energy functions, separating Mega Charizard X and Y into individual energy pools instead of sharing a single resource. Players were also reportedly granted equal amounts of both energy types after the adjustment.
Many players now believe this system change was implemented specifically to support Mega Mewtwo X and Y ahead of GO Fest 2026.
The same leak additionally claims that Mega Raichu X and Mega Raichu Y are being planned as future additions as well, suggesting Niantic may significantly expand alternate Mega forms in the coming years.
GO Fest 2026 Could Be Pokemon GO’s Biggest Event Yet
Pokemon GO is currently celebrating its tenth anniversary period, and GO Fest 2026 is shaping up to be one of the game’s largest events to date.
The live event schedule begins May 29 in Tokyo before moving to Chicago and Copenhagen. Pokemon GO Fest Global is then expected to run worldwide on July 11 and July 12.
Between the rumored Mega Mewtwo release, new Super Mega Raids, anniversary celebrations, and possible future Mega Evolution reveals, many players already see this year’s GO Fest as a major turning point for Pokemon GO’s long-term future.
For now, trainers should still treat the Mega Mewtwo information as unconfirmed leaks until official announcements are made. Still, if these details are accurate, Pokemon GO may soon introduce the strongest Mega Evolutions the game has ever seen.
