How to Mega Evolve in Let’s Go

You need two things: the Key Stone, which every player gets from Blue, and the Mega Stone of that Pokemon.

  1. Get the Key Stone

    Once you hold seven Badges, the Viridian City Gym is still locked, so you head back to Pallet Town. Blue gives you the Key Stone in Professor Oak’s Lab, with the Venusaurite, Charizardite X, Charizardite Y and Blastoisinite.

  2. Carry the Mega Stone

    Each Mega needs its own stone. It only has to be in your bag: Pokemon do not hold items in Let’s Go.

  3. Mega Evolve in battle

    Pick Mega Evolution at the start of a turn. You can Mega Evolve one Pokemon per battle. With both of its stones, Charizard lets you pick X or Y.

  4. It lasts one battle

    The Pokemon changes back when the battle ends. The stone is not used up, so you can Mega Evolve again in the next battle.

Every Pokemon Let’s Go Mega Evolution

Each card shows the Mega form, how much stronger it gets, its new weaknesses and the stone it needs. Tap a name to open that Pokemon on its Mega view.
