Pokémon Sun and Moon have been available for less than two weeks now, but the games already have their second distribution event. Players can still unlock Munchlax along with Snorlium Z through Mystery Gift, but a rarer Pokémon can also be obtained now, this one through the scan of a QR code.
By scanning the code above, players can obtain the mythical Pokémon Magearna. Unlike previous distribution events, there is no deadline; the scan will apparently work indefinitely! This is the first release for the Steel and Fairy-type Pokémon. Magearna was the first new Pokémon revealed from Generation VII, debuting in the movie Volcanion and the Mechanical Marvel. It is currently the only Pokémon capable of learning Fleur Cannon, a powerful Fairy-type attack.
Magearna can only be obtained after the main story has been completed in Sun or Moon. The Pokémon must be picked up from the deliveryman at the Antiquities of the Ages shop located in Hau’oli city. While the Pokémon is not available to those with Pokémon X, Y, Omega Ruby or Alpha Sapphire, the final legendary distribution event for 2016 is currently going on for those titles as well. Meloetta is available until December 24.
