Primal Reversion

is a concept introduced in Pokémon Omega Ruby and Pokémon Alpha Sapphire. It is similar to Mega Evolution, except that the Pokémon goes back into its ancient, original form, where it regains the true, ultimate power it formerly had. The only known Pokémon that are able to do this are Groudon and Kyogre. Primal Reversion is represented with the symbol Ω (Omega) for Groudon () and the symbol α (Alpha) for Kyogre (). The keys to Primal Reversion are the Red and Blue Orbs, both used by their respective counterparts.
==Legend==
In the Hoenn region, it is believed that two extremely powerful Pokémon existed: Groudon, who formed the land, and Kyogre, who formed the seas. They are talked about in a legend:
In some places, cave paintings depicting the legends and the two Pokémon can be found.

There are also legends about Mega Rayquaza, who has some kind of relation with Primal Reversion:

==Trivia==
*Unlike Mega Evolution, Pokémon automatically revert into their Primal form when starting battle. Primal Reversion is also unlimited in terms of how many times it can be activated.
*Pokémon Mystery Dungeon: Explorers of Time and Pokémon Mystery Dungeon: Explorers of Darkness featured Primal Dialga as a final boss. However, Primal Dialga is just Dialga after losing control of its powers and going berserk because of Temporal Tower's destruction. "Primal" in this case refers to the Pokémon being evil or corrupted rather than returning to its original form.
*Primal Kyogre and Primal Groudon's abilities, Primordial Sea and Desolate Land, are both a reference to life on Earth. Primordial Sea refers to the primordial soup that first brought about life, while Desolate Land refers to the eventual end of the world. They also reference Alpha and Omega's statuses as the first and last letters of the Greek alphabet.
