Primal Reversion (Japanese: ゲンシカイキ Primal Regression) is an ancient transformation that debuted in Omega Ruby and Alpha Sapphire. Pokémon that have undergone Primal Reversion are distinguished by the word "Primal" in front of their species name. It is similar to Mega Evolution, but instead of using the energy of people and Pokémon, the user instead absorbs the energy of nature to greatly increase its power. Primal Reversion is said to restore the true powers of a Pokémon.
In order to undergo Primal Reversion, a Pokémon only needs to be holding the appropriate Orb. Like Mega Stones, Orbs cannot be removed if held by the appropriate Pokémon. Unlike Mega Evolution, however, the player doesn't need a Mega Bracelet, and also does not have to manually trigger Primal Reversion; it will simply happen automatically after the Pokémon enters battle and after any entry hazards take effect, but before the activation of weather-changing Abilities. Also, unlike Mega Evolution, there is no limit to the number of times the player may perform a Primal Reversion per battle.
Pokémon capable of Primal Reversion
In the anime
Primal Groudon and Primal Kyogre both appeared in SS032, where they had a clash with one another off the coast of Rustboro City. Alain and Steven attempted to fight the ancient Pokémon with their Mega Charizard X and Mega Metagross, but were soon overpowered. Soon after, Mega Rayquaza appeared, battled, and eventually managed to defeat the two Primal Pokémon, causing them to return to their regular forms.
Primal Groudon and Primal Kyogre are both set to appear in Hoopa and the Clash of Ages.
In the TCG
Primal Reversion will be brought into the Trading Card Game with the release of Primal Clash (Gaia Volcano • Tidal Storm in Japan). Primal Reversion is an extension of the Mega Pokémon-EX mechanic, evolving from the long-standing Pokémon-EX. The only Primal Pokémon-EX are the Primal Kyogre-EX and Primal Groudon-EX being released in the expansion. Although not exclusive to the mechanic, each Primal Reversion Pokémon features a new card effect named Ancient Trait, providing an additional effect for each card.
