Primal Reversion

Primal Reversion is an additional, temporary form of specific Pokémon, similar to Mega evolution. They have greatly increased Combat Power, but their HP remains the same. When a Pokémon is in its primal form, the Trainer receive bonuses. Primal form Pokémon can be assigned as a Buddy Pokémon and used to battle in raids and Gyms or Trainer Battles (including against other players, Team Leaders, Team GO Rocket members, and Challengers in events). However, they cannot be deployed to defend Gyms, traded, powered up nor used in GO Battle League matches (outside of specific events).

Reverting a Pokémon to primal form
In order to revert a Pokémon to its primal form, Trainer needs Primal Energy of specific Pokémon.

Pokémon will remain in their Primal form for 8 hours. It will enter rest period once it expires. Only one of Trainer's Pokémon can be in Primal form at any particular time. If another Pokémon is reverted, the previous reverted Pokémon will change back to standard form and enter rest period. Pokémon can also be primal reverted in a raid lobby or Trainer Battle preparation screens.

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

Primal Energy
Primal Energy is a consumable resource that is similar to Pokémon Candy and Mega Energy, as each Pokémon species has specific Primal Energy.. Unlike Candy, each individual type of Primal Energy has a limit of 2000 in Trainer collection.

Primal Energy for a particular species can be received by battling that specific Pokémon in Primal Raids, a special Tier of Raid Battles, or completing research tasks. Completing a Primal Raid in a shorter time would award more Primal Energy, which is given upon completion of the raid and does not require a catch. Buddy Pokémon can earn corresponding 5 Primal Energy per km via walking (along with the usual Candy).

Primal reverting a Pokémon for the first time costs a high amount of Primal Energy. Primal reveting that single Pokémon subsequent times do not require Primal Energy again, if its rest period is over. Primal Energy can be used to skip the rest period. The Primal Energy cost will gradually decrease along with the rest period drops. Primal reverting other Pokémon of the same species still requires full cost.

Primal Level and bonuses
Primal reverting a Pokémon progresses that specific Pokémon's Primal Level and unlocks increasing bonuses.

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

Higher Primal Level reduces the Primal Energy cost to skip the rest period. The Primal Energy data shown below refers the cost required right after the Primal reversion is over.

While a Pokémon is reverted to primal form, the Trainer gain bonus Candy for catching Pokémon that share a type with the Primal reverted Pokémon, or for any raid boss caught. These do not stack with each other.

The bonus XP also only applies to Pokémon that share a type with the Primal reverted Pokémon.

If a Pokémon that has previously been Primal reverted is traded, their Primal Level is reset, and that Pokémon is considered to have never Primal reverted at all.
