Both of Mewtwo’s Mega Stones are now available for download in Pokémon Sun and Moon!
In order to receive the items, you must take the following steps:
- From the main menu, select “Mystery Gift” instead of “Continue”
- Select Receive Gift, then “Receive via code/password”, and then select “Yes” twice to connect to the Internet
- Enter the code: M2DESCENT
- Visit a deliveryman in any Pokémon Centre to receive both stones
- Save your game
You can’t get Mewtwo in-game, but you can transfer it from X and Y via Pokémon Bank. You’ll then be able to experience Mega Mewtwo in action in Alola for the very first time.
