Niantic is releasing a new Mega Evolution feature for Pokémon Go, bringing more powerful evolved forms of certain pokémon to the game. Mega Evolution was introduced to the mainline Pokémon series in Pokémon X and Y and continued in Sun and Moon, but it doesn’t appear in the most recent games Sword and Shield, which have a similar feature called Dynamax.
In Pokémon Go, Mega Evolution is handled with a new resource called Mega Energy that is earned by battling Mega-Evolved pokémon in raids. You can Mega Evolve pokémon including Beedrill, Blastoise, Charizard, and Venusaur once you have enough energy. The pokémon will become much stronger in their new forms, so Mega Evolution is likely to have major implications for high-level play.
