Mega Evolution

Mega Evolution is an additional, temporal evolution form of specific Pokémon that reached their final evolution stage.

Mega Pokémon are more powerful forms of Pokémon with their attacks boosted as well as their Combat Power. Moreover, Mega Pokémon will boost the attack power of all other Pokémon when battling in Raids. Pokémon with the same type as the Mega Evolved Pokémon will receive an even greater attack boost. HP of Mega Evolved Pokémon is the same as its standard form.

Similarly to the main series games, Mega Evolution is temporary, however in Pokémon GO it is a temporal change of form that occurs in Trainer's Pokémon collection instead of a single battle.

Mega Evolved Pokémon can be assigned as a Buddy Pokémon and used to battle in raids and Gyms or against another Trainers and Team GO Rocket members. However, they cannot be deployed to defend Gyms, traded nor used in GO Battle League matches.

Mega Evolving a Pokémon
In order to Mega Evolve a Pokémon, Trainer needs Mega Energy of specific Pokémon.

Pokémon will remain in their Mega form as long as they have enough Mega Energy to continue to do so.

Only one of Trainer's Pokémon can be Mega Evolved at any particular time.

Each Mega Evolved Pokémon for first time is registered to the Mega Pokédex.

Mega Energy
Mega Energy is a consumable resource that is similar to Pokémon Candy, as each Pokémon species has specific Mega Energy. While a Pokémon is Mega Evolved, its Mega Energy will deplete over time.

Mega Energy for a particular species can be received by battling that specific Pokémon in Mega Raids – another tier of Raid Battle.
