what is primal reversion

Primal Reversion is a transformation that certain Pokémon can undergo, similar to Mega Evolution, which gives them a new appearance and improves their abilities. It is powered by natural energy and can affect the weather. In Pokémon Go, Primal Reversion was introduced as part of Go Tour Hoenn in February 2023, allowing Kyogre and Groudon to become even stronger. To undergo Primal Reversion, a Pokémon needs to have enough Primal Energy, which can be obtained by participating in Primal Raids. Currently, only Kyogre and Groudon can undergo Primal Reversion in the main series, and they were first introduced in Pokémon Omega Ruby and Alpha Sapphire. Unlike Mega Evolution, which has many forms in the main series, there are only two Primal forms currently available. It is possible that more Primal forms could be introduced in the future, but this is unlikely without them debuting in the main series first.
