Add more Mega Stones to your collection so you can Mega Evolve more Pokémon in Pokémon Sun and Pokémon Moon with a special code. When you enter the following password in your game, you'll receive Pidgeotite, Steelixite, Heracronite, and Houndoominite Mega Stones, the items needed for Pidgeot, Steelix, Heracross, and Houndoom to Mega Evolve during battle.
Mega Stones password: AZUL
These Pokémon aren't available in the wild in Pokémon Sun or Pokémon Moon, but you can bring them into Pokémon Bank via Poké Transporter from earlier games. The Pokémon you transfer will lose their items in the process, however, so this distribution is currently the only way to get these Mega Stones in Pokémon Sun or Pokémon Moon.
To get the four Mega Stones:
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 your password.
Watch as you receive the Mega Stones.
Speak to the deliveryman in any Pokémon Center to pick up your Mega Stones.
Be sure to save your game!
Enjoy bigger battles with the force of Mega Evolution in Pokémon Sun and Pokémon Moon with these awesome Mega Stones!
Also, make sure you enter this password by October 31, 2017. That's the final day for Trainers to claim their special Mega Stones, so don't miss out on this opportunity to unlock your Pokémon's Mega Evolutions!
