Mega Evolution arrived in Pokémon UNITE with Mewtwo X and Mewtwo Y, then spread to other Pokémon. Unlike the main games, it isn’t permanent: the Pokémon Mega Evolves for a limited time, and can do so again later in the match.
How it works
- The Pokémon holds its Mega Stone: an exclusive held item, unlocked automatically with its Unite License.
- The condition is met during the match, depending on the Pokémon.
- The Pokémon Mega Evolves for a limited time: its stats increase and some moves are strengthened.
- It returns to its normal form, then can Mega Evolve again when the condition is met once more.
