Mega Mewtwo is the headline addition to Pokémon Go Fest 2026.
Debuting first during in-person Go Fest events during the summer, it was made available to all players during the Go Fest Global weekend in 2026.
Here's how to get Mega Mewtwo in Pokémon Go over the Go Fest: Global weekend - plus Mewtwo Mega Evolution level requirements and how Mewtwo Mega Energy works.
Elsewhere, joining Mega Mewtwo at Go Fest as a new debut is Zeraora, the Gen 7 Mythical.
Update (11th July): Tweaked the guide for the Go Fest Global weekend, including a new Mewtwo Mega Energy source.
How to get Mega Mewtwo in Pokémon Go
Mega Mewtwo will be available to everyone for free during Go Fest: Global in July, with those attending in-person Go Fest events in May and June receiving early access. The dates and specific rollouts are as follows:
- In-person Go Fest events (Tokyo, Chicago, Copenhagen in May-June):
- Completing research from the City Explorer ticket or weekend ticket for a Mewtwo with one Mega Evolution unlocked (X or Y)
- Completing a Unity Raid hosted at the end of the park session
- Go Fest: Global (11th to 12th July):
- Completing branching research for a Mewtwo with one Mega Evolution unlocked (Mega Mewtwo X or Y)
- Facing Mega Mewtwo X and Mega Mewtwo Y in Super Mega Raids for Mega Energy
Mewtwo has two Mega Evolutions - Mega Mewtwo X and Mega Mewtwo Y. Go Fest attendees get access to branching research which rewards a Mewtwo that can automatically Mega Evolve into their chosen evolution. If you want to get the other Mega Evolution, then you must participate in Super Mega Raids.
How to get Mewtwo Mega Energy in Pokémon Go
The three confirmed Mewtwo Mega Energy sources in Pokémon Go are as follows:
- Completing Mega Mewtwo raids (up to 450 Mega Mewtwo X or Y Energy will drop specific to that branching evolution) during Go Fest: Global in 11th to 12th July (X appears on Saturday, Y on Sunday)
- Completing 'Win a raid' Timed Research for 150 Mega Mewtwo Energy during the Go Fest: Global weekend
- Walking Mewtwo as your Buddy (drops 100 Mega Energy per 20km) when Mega Mewtwo is unlocked in your Pokédex
- Walking will reward both X and Y Mega Energy, but only if both are unlocked in your Pokédex first
Your best source, then, is completing Mega Mewtwo raids - but it's also worth looking out for the Timed Research over the weekend, as well as keeping a Mewtwo as your Buddy as you go for additional drops.
Mewtwo Mega Evolution level requirements
The requirement to Mega Evolve Mewtwo is 7,500 Mega Energy for the first level, with more Mega Energy required to level it to the highest Mega Level.
Here's the full set of requirements (thanks pinakasuperman on reddit for confirming these):
- Mega Level 1 (Base): 7,500 (mandatory)
- Mega Level 2 (High): 800 (optional)
- Mega Level 3 (Max): 2,640 (optional)
- Mega Level 4 (Super Max): 7,640 (mandatory)
This means you need 15,140 Mewtwo Mega Energy minimum for each X and Y Mega Evolution, provided you don't mind unlocking Level 2 and 3 through Mega Evolving and waiting for cooldowns, or 18,580 Mewtwo Mega Energy if you want to reach Level 4 immediately.
However, to help, there are a few ways to evolve Mega Mewtwo without spending Mega Energy...
How to Mega Evolve Mewtwo for free
First, as with all Mega Evolutions, Mega Levels can be increased for free by Mega Evolving them over and over when each 'cooldown' period ends, provided you have Mega evolved it once previously. The final level, meanwhile, always requires Mega Energy, which is 7,640 Mega Energy in Mega Mewtwo X or Y's case.
Additionally, all Mewtwo caught after a Mega Mewtwo raid during a Go Fest event (for those with a Tokyo, Chicago, and Copenhagen ticket, or Global) have the first Mega X or Mega Y level unlocked automatically, and a chance of level two or three also being unlocked.
You can see an example of two Mewtwo having Mega Level three unlocked automatically in the following video:
This means don't have to worry about that initial steep Mega Energy requirement for Mewtwo caught at Go Fest 2026. However, this only applies to either the Mega Mewtwo X or Y evolution, with the one you unlock being dependent on the raid you completed.
In other words, Go Fest can help you get an initial Mega Mewtwo X or Y (with a free encounter as part of the 'Genetic Mastery' quest) but you then still have to get Mega Energy for the other Mewtwo Mega Evolution. And if you'd rather Mega Evolve a Mewtwo caught before Go Fest? That then requires 7,500 Mega Energy for each initial X and Y evolution.
So, unless you have a sentimental Mewtwo in your collection, it's worth catching a new one during a Go Fest weekend (ideally one that's shiny and / or has a location or special background) to give you a leg up on one of the X or Y evolutions. From there, you can participate in Mega Mewtwo Raids or walk Mewtwo as your Buddy to get the remaining Mewtwo Mega Energy you need.
Which Mewtwo can Mega Evolve?
Finally, if you do have a prior Mewtwo in your collection you'd prefer to Mega Evolve, know that almost all in your existing Mewtwo in your collection have the potential to do so, provided you have enough Mega Energy.
The two exceptions, however, are Armored Mewtwo and Shadow Mewtwo - neither of which can Mega Evolve.
If you aren't sure, go to your Mewtwo's stats screen, and see if the option to Mega Evolve is available. If it appears, then that Mewtwo can be Mega Evolved provided you have the energy.
