Those who missed the chance to obtain the Mythical Pokemon Darkrai at GameStop earlier this year will have another chance to obtain the legendary creature.

From now until October 31st, owners of Pokemon Omega Ruby/Alpha Sapphire and X/Y can input the code “Darkrai20” into the mystery gift function to receive Darkrai. It is the same Darkrai that was given away at GameStop earlier this year. Players who received it then will not be able to get a second one.

This is the third time this year that Darkrai has been given away. Along with the GameStop giveaway, members of the Trainer Club were given a chance to pick up Darkrai in August.

A recent trailer for the latest games in the series, Pokemon Sun and Moon, showed off some of the new features that are coming to the games. Trainer customization will be in Sun and Moon, and will allow players to choose their outfits, hairstyle, and eye color. There will also be a new mode called Pokemon Refresh, which will allow players to interact with and groom their creatures. Also shown in the trailer were new Z-moves for both Pikachu and Eevee.

Pokemon Sun and Moon will release on November 18th for the Nintendo 3DS.
