It has been a couple of months since the announcement was made and now the time has come. You can finally catch them all (in the Kalos region) by including Volcanion in your party. This mythical Pokémon was first discovered upon the release of Pokémon X and Y but trainers could never get one until now.
Volcanion will be available via download code which can only be found at participating GameStop store. There is no purchase necessary, just show up and ask for a code card to enjoy your new Pokémon. The cards are only available from October 10 until October 31. If you have been waiting to get your hands on Volcanion, there is no time to waste. It may be the final Pokémon you need to complete your X, Y, Alpha Sapphire or Omega Ruby Pokédex.
This comes with perfect timing as you could even transfer Volcanion over to Pokémon Sun and Moon as soon as the Pokémon Bank process updates. Take a look at the trailer below and head out to a store nearest you.
