Primal Reversion is a temporary transformation that causes Groudon and Kyogre to change appearance, become more powerful, and grant in-game bonuses in Pokemon GO.

To change Groudon or Kyogre into their Primal forms for the first time, you will need to spend 400 Groudon or Kyogre Primal Energy.

For more information on this, check out our guides on how to get each of these Primal Pokemon:

After Primal Reversion, Groudon and Kyogre stay in their Primal forms for eight hours. All of the bonuses they activate last that long too!

Additionally, each time you use Primal Reversion on each of these Pokemon, the amount of Primal Energy needed to transform them decreases and their Primal Level increases!

What is Primal Level in Pokemon GO?

Primal Level determines how strong the bonuses of your Primal Pokemon are. The higher the Primal Level, the stronger the bonuses.

Every time you use Primal Reversion to change Groudon or Kyogre into its Primal form in Pokemon GO, its Primal Level increases slightly.

This system is extremely similar to the Mega Level for Mega Pokemon, but Primal Groudon and Kyogre have unique bonuses. You can find them here:

What Pokemon Have Primal Versions?

Only two Pokemon have Primal versions in Pokemon GO, they are Groudon and Kyogre.

These are also the only two Pokemon that have Primal versions in the mainline series, so don’t expect any more Legendary Pokemon to get a Primal version in Pokemon GO.

However, there are loads of Pokemon that have Mega Evolutions in Pokemon GO! You’ll want to earn plenty of Mega Energy so you can get every Mega Pokemon in Pokemon GO!
