Mega Evolution

Mega Evolution is an additional, temporary evolution form of specific Pokémon that reached their final evolution stage. They have greatly increased Combat Power, but their HP remains the same. Certain Pokémon may also change their types after being Mega Evolved.

Mega Pokémon will boost the attack power of all other Pokémon when battling in Raid Battles by 10%. Attacks that share their type with the Mega Pokémon's type(s) receive a 30% boost. However, these bonuses do not stack if there are multiple Mega-Evolved Pokémon battling simultaneously, only the higher will be applied.

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, Powered Up nor used in GO Battle League matches while Mega Evolved.

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 for 8 hours. Only one of Trainer's Pokémon can be Mega Evolved at any particular time. If another Pokémon is Mega Evolved, the previous Mega Evolved Pokémon will revert to standard form.

While a Pokémon Mega Evolved, the Trainer gain +1 bonus candy for any raid boss caught, and +1 bonus candy for any Pokémon caught that share a type with the Mega Evolved Pokémon. These two bonuses do not stack.

If Pokémon such as Charizard has different Mega Evolution forms, Trainer can choose into which one they want to Mega Evolve such Pokémon.

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

Clone and Shadow Pokémon cannot be Mega Evolved. Purified Pokémon can be Mega Evolved, but they do not have their white aura while Mega Evolved.

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. Unlike Candy, each individual type of Mega Energy has a limit of 2000 in Trainer collection.

Mega Energy for a particular species can be received by battling that specific Pokémon in Mega Raids – a special Tier of Raid Battles or completing Research tasks.

Buddy Pokémon can earn corresponding Mega Energy via walking (along with the usual candy) if it is part of previously a Mega-Evolved Pokémon's Evolutionary line. For example, if a Trainer had registered Mega Venusaur in their Pokédex, any Bulbasaur, Ivysaur and Venusaur can earn Mega Energy when assigned as Buddy Pokémon.

Mega Evolving a Pokémon for the first time costs a significant amount of Mega Energy, Mega Evolving that single Pokémon subsequent times will cost less energy. Mega Evolving other Pokémon of the same species still requires full cost. Pokémon like Charizard have two Mega forms, both of them require to be unlocked at full cost first.

If a Pokémon that has previously been Mega Evolved is traded, they retain this discount. However, it does not unlock walking them for Mega Energy (although it would be easier to unlock due to the discount).

Reception and adjustments
Despite being highly-anticipated by the community, Mega Evolution caused a public backlash regarding its implementation. A Reddit post criticizing Mega Evolution received over 8000 upvotes and 100 rewards within the launch day. Many have pointed out the duration of Mega Evolution is not worth the Raid Passes spent on collecting Mega Energy. The difficulty of Mega Evolving one's desired species is also in concern due to specific Mega Energy and the rarity of Mega Raid Battles.

Since there is specific Mega Raid Bosses pool, there would be no way to Mega Evolve any Pokémon that has its Mega Evolved form released but is no longer available in Mega Raids. Initially, once all Beedrill Mega Energy from A Mega Discovery was used, there was no possibility to continue on Mega Evolving Beedrill for a longer time period.

Competitive players have expressed their worries of Mega Evolution greatly enlarging the gap between free players and "whales". Mega Evolving Pokémon daily takes 1 to 2 Raid Passes to gather Mega Energy, which is impossible to catch up for free players.

Outside of Mega Evolution, replacing team contribution with speed bonus does harm to Premier Balls in Tier 5 Raid Bosses. It is impossible to defeat certain Legendary Pokémon in a short time, even for large group, while having more Trainers mean lowering the damage bonus.

Regarding to this, Niantic has made a statement "We are actively listening to your feedback and look forward to sharing more about how this feature will grow in the future." in the Pokémon GO official Twitter page.

On September, 2020, several updates were made after listening to feedback. The Mega Evolution cost of subsequent Mega Evolution was reduced. Amount of Mega Energy given from Mega Raids was increased. Niantic also announced that they are working on implementing features which would allow Trainers to obtain Mega Energy in more ways.

On October, 2020, the duration of Mega-Evolved form has doubled from four hours to eight hours. The cap of each individual type of Mega Energy has increased from 999 to 2000.

Since November, 2020, more updates were added, including:
 * Earning corresponding Mega Energy from Buddy Pokémon if it is part of previously Mega-Evolved Pokémon's Evolutionary line. Detail is described above.
 * Earning additional Candies when Trainers catch a Pokémon that shares a type with the active Mega-Evolved Pokémon. Additional Candies are given from catching Raid Bosses regardless of their types.

On April, 2022, along with A Mega Moment, new mechanics for Mega Evolution were released.
