To use Mega Evolution in Pokémon GO, capable Pokémon must consume Mega Energies. Many big changes were made to Mega Evolution mechanics to accommodate for Pokémon GO's mobile format, to make the special evolutions work better for gameplay. However, this was never officially confirmed.Īdditionally, Mega Evolution released for Pokémon GO in the summer of 2020. This could be because Game Freak had never added a battle mechanic similar to Mega Evolution in the previous 5 Pokémon Generations, and the developers were hoping the ability would be better received if given to already popular Pokémon, who could hype the ability with interesting new designs. Instead, the focus for the mechanic was placed on Pokémon species who were popular in previous generations. Oddly, despite Mega Evolution being a key mechanic in Pokémon X and Y, it was not applied to the region-specific Legendary Pokémon for Kalos. The version each Pokémon gets depends on the Mega Stone they are holding, which are version-exclusive to either Pokémon X or Y. Charizard and Mewtwo each were given two different Mega-Evolution forms, Mewtwo X or Y, and Charizard X or Y. These included the fully-evolved Kanto starters, as well as Legendary Pokémon like Latias, Latios, and Mewtwo. Mega Evolution in Pokémon X and Y introduced 28 capable Pokémon species. Mega Evolution is supposed to be the physical manifestation of the bond between a Pokémon and its trainer, and only those who have a powerful partnership are able to achieve the ability. However, in Omega Ruby and Alpha Sapphire, the Legendary Pokémon Rayquaza is said to be the original Pokémon capable of the ability. The lore for the origins of Mega Evolution change depending on the Pokémon game being played. It is stated in Pokémon X and Y that the first Pokémon capable of Mega Evolution was the Fighting-type Lucario. Mega Evolution inspired the Primal Reversion forms of the Legendary Pokémon Kyogre and Groudon in the 3DS remakes Omega Ruby and Alpha Sapphire, though they aren't considered Mega Evolutions.

A Pokémon stays Mega Evolved even if it is recalled to its Pokéball during a battle or wild encounter and will only revert after the battle has ended, or the Pokémon is knocked unconscious. However, it doesn't have the turn-based time limit that Sword and Shield placed on Dynamax abilities. Like Dynamax and Gigantimax, Mega Evolution can only be used once during a battle. Currently, there are 46 Pokémon species who possess the ability to Mega Evolve.
