To use Mega Evolution in Pokémon Champions, give the correct Pokémon its matching Mega Stone, then trigger Mega Evolution during battle when that Pokémon is active. The game’s guides also note that you can only Mega Evolve once per match, so choose the best moment carefully.

How it works

First, equip the species- specific Mega Stone in the team or item menu before the battle starts. For example, Gengar needs Gengarite, and the stone must be on the Pokémon you want to Mega Evolve.

Once the battle begins, select that Pokémon and activate Mega Evolution during your turn; guides describe this as pressing the Mega Evolution prompt/button after choosing the move or while confirming your action. The transformation happens in battle, not from a menu outside the match.

Important rules

  • Only one Pokémon on your team can Mega Evolve per battle.
    • [6][5]
  • The Mega Stone is species-specific, so the wrong stone will not work.
    • [4][7]
  • Once you Mega Evolve, that form lasts for the rest of the match.
    • [7]
  • Because it uses a held item slot, the Mega Stone takes the place of any other held item.

Simple example

If you want Mega Charizard X, equip Charizard with its matching Mega Stone before the fight, bring it into battle, and activate Mega Evolution when Charizard is on the field. That lets Charizard transform and gain the Mega form for the rest of the match.
