Mega Mewtwo in Pokémon Sun and Moon? Sure, why not!
If you’ve brought Mewtwo into the game using the Pokémon Bank, there’s a now-active code for Mewtwonite X and Mewtwonite Y, the Mega Stones needed for it to evolve into Mega Mewtwo X and Mega Mewtwo Y, respectively. That code is “M2DESCENT” and it’s the only way to make this happen currently since held items (in this case Mega Stones) are lost in the Bank transportation process.
- Select Mystery Gift on the main menu.
- Select Receive Gift.
- Select Get with Code/Password, then Yes, and then Yes again to connect to the Internet.
- Enter the code M2DESCENT
- Watch as you receive Mega Stones!
- Speak to the deliveryman in any Pokémon Center to pick up your Mega Stones.
- Be sure to save your game!
You and your Mewtwo are now free to run off and terrorize Alola as you please.
Also, I stumbled on this gif and it’s a very unsettling gif indeed. Look away!
