How it works

How to Mega Evolve in Let’s Go Pikachu & Eevee

Items and rules

Get the Key Stone. After your seventh badge, Blue hands it to you in Professor Oak’s Lab in Pallet Town, along with the Mega Stones of the three Kanto starters.
Keep the Mega Stone in your bag. The Pokémon does not have to hold it.
Choose your Mega. You can Mega Evolve one Pokémon per battle.
One starter, two forms. Charizard can become Mega Charizard X or Mega Charizard Y, and you pick between them as it Mega Evolves.
Mega Evolution wears off. The Pokémon changes back to its usual form when the battle ends.

Our nature pick is RB’s own take, not a game rule: it raises the Mega’s highest stat and lowers its lowest one, HP aside, and on a tie it takes the stat listed first.
