You’ll only be able to Mega Evolve Beedrill, Blastoise, Charizard and Venusaur at the outset. When you do, they’ll be much more powerful. They’ll amp up the attack power of allied Pokémon during raids too.

Only one of your Pokémon can be Mega Evolved at a given time. They’ll stay in that form until they run out of Mega Energy. After you Mega Evolve a Pokémon once, it’ll cost less Mega Energy to do so with that creature in the future.

Several Mega Evolution-themed events will take place in Pokémon Go throughout September. According to Polygon, Niantic will roll out the Mega Evolution update on Thursday on Android and iOS.
