Add the power of Mega Evolution to any Mewtwo you have in your Pokémon Sun or Pokémon Moon game!
3 March. London, United Kingdom. The Legendary Pokémon Mewtwo is already formidable in battle, but when it Mega Evolves into Mega Mewtwo X or Mega Mewtwo Y it becomes even more powerful. And now you can get Mewtwo’s Mega Stones in your Pokémon Sun or Pokémon Moon game via a special code. Give Mewtwo either a Mewtwonite X or Mewtwonite Y to hold to have it Mega Evolve two different ways during battle.
