Mega Mewtwo X and Y will be up for grabs during the Pokemon GO Fest Global 2026, and deciding which mega evolution to choose for your Mewtwo might be a tough choice. Both variants are strong and boast some of the highest stats in the entire game. However, one of these two has a clear edge, especially in the generalist category that dominates the raid metas.

You will be able to catch a Mega Mewtwo X or Y from the Super Mega Raids during Pokemon GO Fest Global 2026 on July 11 and 12, 2026, from 10:00 AM to 6:00 PM local time. However, if you have an existing Mewtwo with good IVs already, you will also be able to evolve it to your desired mega form.

Mega Mewtwo Y is the better mega evolution for Mewtwo in Pokemon GO. This article will explain why Mega Mewtwo Y is the better choice and how it does better than Mega Mewtwo X in the game.

Here is a basic comparison of Mega Mewtwo X and Y's stats and details in Pokemon GO:

Since both the mega evolutions have a Psychic-typing, let us first compare them in under the same meta conditions. At level 50, Mewtwo Mega Y with Psycho Cut and Psystrike (Fast and Charged Attacks, respectively) does 26.58 DPS and 810 TDO (total damage output) in Pokemon GO. With the same Fast Attack and Charged Attack, Mega Mewtwo X does 25.75 DPS and 758.2 TDO.

While both of these values are high in their own regard, Mega Mewtwo Y manages to dethrone Mega Rayquaza (Dragon Tail + Dragon Ascent) in terms of TDO. This makes Mega Mewtwo Y have the highest total damage output in all of Pokemon GO, instantly putting it into the top tier of generalist Pokemon.

In the Fighting-type category, Mega Mewtwo X once again misses out on the top spots, which are taken by Mega Lucario forms. Mega Mewtwo X manages to hold a better position in the Psychic-type category here, since its dual typing makes it more susceptible to attacks from Dark-types that normal Fighting-types would normally resist.

Finally, as a complete generalist Pokemon, Mega Mewtwo X once again sits below its Y counterpart. Although the top spot is still taken by Mega Rayquaza, both the Mewtwo megas fit in the top five bracket, making them strong contenders for raid attackers.

Taking all into consideration, Mega Mewtwo Y stands out as the superior choice in Pokemon GO. It delivers great performance as a generalist raid attacker, and its higher attack stat and max CP directly translate into better raid efficiency. On the other hand, Mega Mewtwo X struggles to dominate any meta in particular, and is outperformed by its competition.

As such, Mega Mewtwo Y is the more versatile and sensible option when evolving your Mewtwo. During the Pokemon GO Fest Global 2026, you should particularly take part in the Mega Mewtwo Y Super Mega Raids to rack up the necessary amount of mega energy for the legendary critter.
