Mega evolutions are temporary power increases in battle, giving your a new form and attack. Evolving Pokémon in Pokémon Sun and Moon into the mega evolutions works a little differently than previous editions. You need a Mega Ring as well as a Mega Stone for each Pokémon you want to mega evolve.

Mega Stones can't transfer into Pokémon Sun and Moon via the Pokémon Bank, so any older versions won't help you here. To mega evolve in Sun and Moon, you'll need to acquire all the Mega Stones within the game itself. Once you have a Mega Stone for your Pokémon, you'll be able to mega evolve in battles. Mega evolution can be triggered only once per battle, and your Pokémon will stay evolved until the battle is over. While they look cool and have more powerful attacks, they also have painful implications.

Mega Evolving Your First Pokémon

Once you have defeated the Elite Four near the end of the game, you can start the process to mega evolve your Pokémon. Head to Ancient Poni Path on Poni Island. When you battle your way down the path toward the Battle Tree, Dexio and Sibb will appear and challenge you. Defeating them will reward you with a Mega Ring, which allows you to mega evolve Pokémon, as well as a Mega Stone for Alakazam to get you started.

Mega Evolving Subsequent Pokémon

Now that you have your Mega Ring, you can mega evolve any Pokémon as long as you have their corresponding Mega Stone. Most Mega Stones can be found at the Battle Tree shop, using points earned from winning battles to purchase them. A couple Mega Stones are rewards from defeating the Red trainer.

Not all the Pokémon have Mega Stones yet. There were some Mega Stones conspicuously missing, which The Pokémon Company noted would show up as rewards for participating in online event competitions in the future. The International Challenge competition in February awarded two Pokémon Mega Stones for Mawile and Beedrill to players who registered and competed in the event. There is currently no other way to acquire those particular Pokémon, though The Pokémon Company said they will repeat the event and offer its rewards in April as well.

Mega Evolving Rayquaza

Rayquaza is unique in that it is the only Pokémon that does not require a Mega Stone to mega evolve, rather it can evolve after learning a new attack. If you have Rayquaza, you can take it to the Seafolk Village PokéCenter on Poni Island. Speak to the Move Tutor there (the man in the red shirt) and he'll teach your Rayquaza the Dragon Ascent move. This then allows your Rayquaza to mega evolve into its more powerful mega form.

Mega Evolving Mewtwo

Mewtwo's Mega Stone isn't technically available in game yet, at least through normal means. However, the addition of the Pokémon Bank allows you to get it if you already had Mewtwo in a previous edition (Pokémon Omega Ruby and Alpha Sapphire, Pokémon X and Y). Transfer Mewtwo to the Pokémon Bank via the Poké Transporter. Follow the steps below to get your Mewtwo Mega Stones to mega evolve into Mewtwonite X or Mewtwonite Y.

  • In Pokémon Sun or Moon, open the main menu and select the "Mystery Gift" option.
  • Select "Receive Gift" in the menu.
  • Select "Get with Code/Password".
  • Select "Yes" to connect to the internet.
  • Enter code "M2DESCENT".
  • Wait for the animation to complete.
  • Go back the game and head to a Pokémon Center.
  • Talk to the deliveryman inside to get your Mewtwo Mega Stones.
  • Save your game.

Hopefully this mega evolution guide helps you out in your Pokémon battles. Happy battling!
