Mega Energy

A certain amount of Mega Energy is required to cause a corresponding Pokémon to undergo Mega Evolution. After a Pokémon has Mega Evolved once, it will enter a rest period. Pokémon can Mega Evolve again at no cost after waiting out a rest period since its last Mega Evolution. The Pokémon can still Mega Evolve during the rest period by using Mega Energy at a reduced cost, which also decreases proportionally with the time remaining in the rest period.

If the Pokémon is later traded, its Mega Level is reset, and it would cost the full amount again to Mega Evolve.

The player can have a maximum of 9,999 of each Mega Energy at a time (2,000 prior to April 28, 2022, and 999 prior to October 15, 2020).

All of the above also applies to Primal Energy.

Mega Energy is received by completing Mega Raids—Raid Battles with Mega-Evolved Pokémon as Bosses. These corresponding to the Boss that was defeated, the amount ranging from 150 to 250 Mega Energy depending on how quickly the raid was completed. Likewise, Primal Raids reward Primal Energy corresponding to the defeated Raid Boss, but at a smaller amount ranging from 60 to 100 Primal Energy.

Mega Energy for certain Pokémon may also be received by completing certain Research tasks.

Occasionally, spinning a PokéStop or Gym may yield 5 Mega Beedrill Energy.

As of November 1, 2020, Mega Energy and Primal Energy will be found by a Buddy Pokémon if the player has previously Mega Evolved a Pokémon in the same evolutionary line and feeds it Candy. The amount that the Pokémon finds is directly proportional to its Buddy distance, at a rate of 5 Energy per 1 km.
