The Pokémon Omega Ruby and Alpha Sapphire website has been updated with details of the next UK Pokémon distribution. At participating GAME stores, you’ll be able to get the Mythical Pokémon Hoopa between October 23rd and November 5th. To be eligible for a Hoopa code for your game, you’ll need to have a copy of Pokémon X, Pokémon Y, Pokémon Omega Ruby, or Pokémon Alpha Sapphire as well as a Nintendo 3DS or Nintendo 2DS.
The Hoopa you receive will be in confined form, but when paired with the prison bottle item in Pokémon Omega Ruby or Alpha Sapphire, it will transform to Hoopa Unbound. There’s screenshots and videos showcasing Hoopa’s Unbound transformation on the official website.
