Pokémon Mega Evolution, added in Generation 6, allows Pokémon to take on new, more powerful forms, but only a few species can do it in battle.
Every new generation of Pokémon has brought with it a new battle mechanic. Traditional Pokémon battles have become more thrilling and challenging thanks to the Dynamax and Gigantamax forms of Sword and Shield, the Z-Moves in Sun and Moon, and the Mega Evolution in X and Y. Although all Pokémon will use a combination of the first two mechanics, only a certain species can Mega Evolve. The list is not as long as some players might want.
When holding the correct Mega Stone, capable Pokémon will evolve into a new, temporary evolutionary form. One capable Pokémon in the party can Mega Evolve for the duration of the fight once per battle. Mega Evolution lasts until the Pokémon is knocked out or, unlike Gigantamaxing and Dynamaxing, until the Pokémon is defeated. Mega Evolution appeared in the games X and Y, Omega Ruby and Alpha Sapphire, and Sun and Moon. It also features several spin-off games, but it’s normally only a bonus there that’s limited to a small list of species. In Pokémon GO, for example, there are only 10 Pokémon that can Mega Evolve at the moment.
Mega Evolution is available to 46 Pokémon in total, with 48 different Mega Evolution forms. Many of these Megas introduced in Pokémon X, and Y and Pokémon Omega Ruby and Alpha Sapphire are all based on Pokémon that can not normally evolve anymore. The prominent characteristics of their base-form Pokémon are often exaggerated in mega designs. Venasaur, for example, gets a much larger flower on its back, and Blastoise gets a single, massive hydro canon instead of two. Mewtwo and Charizard both have two Mega forms, and which one they transform into is determined by the Mega Stone they are holding.

The Legendary Pokémon Kyogre and Groudon differ from the other Mega Evolutions in many ways. They can transform into Primal Reversion forms if they have the right Reversion Orb. While Primal Reversion is actually a different mechanic in that it allows players to Mega Evolve a compatible Pokémon in the same battle, the systems are nearly similar. Kyogre and Groudon are now the only Pokémon in the series with Primal Reversion forms.
- Primal Reversion Kyogre – Water; Ability: Primordial Sea; Reversion Orb: Blue Orb
- Primal Reversion Groudon – Ground/Fire; Ability: Desolate Land; Reversion Orb: Red Orb
