Mewtwo was already a dangerous opponent in battle. Mew will become even more dangerous if you Mega Evolve it into Mega Mewtwo X or Mega Mewtwo Y. You can get these stones from special codes.
Give Mewtwo Mewtwonite X or Mewtwonite Y to evolve Mew into two different versions during a fight.
The Mewtwo Mega Stone code is: M2DESCENT
You can’t find Mew in the wild, so you have to bring Mew into the game by putting it into the Pokémon Bank through the Poké Transporter from some of the earlier Pokémon games. This is currently the only way to get Mega Mewtwo X and Y.
To acquire the Mega Stones:
- Select Mystery Gift on the main menu
- Pick Receive Gift
- Select Get with Code/Password, then Yes, select Yes again to connect to the Internet
- Enter your code
- Receive Mega Stones
- Speak to the deliveryman in any Pokémon Center to pick up your Mega Stones
- Make sure to save your game
