Pokémon Bank, the Nintendo 3DS application that lets players store and trade Pokémon between a selection of mainline games, will receive a big update in January 2017. Much of what’s coming to the app has been previously confirmed, but the Pokémon Sun and Moon site also describes a new addition to the app beyond compatibility with the new games: a national Pokédex.
The Pokédex will collect data from any supported Pokémon game that connects with it, populating with every Pokémon a trainer has caught. The feature will let you take a look at your entire Pokémon collection across all of the Nintendo 3DS titles, even if those Pokémon aren’t stored in the Bank itself. Consider this the ultimate Pokédex.
That aside, the January 2017 update will also make Sun and Moon compatible with both the app and the Virtual Console re-releases of the original Game Boy games. Using the Poké Transporter tool, players can get their retro Pokémon into the more modern Sun and Moon.
Sun and Moon launch Nov. 18, so players will have plenty of time to get acclimated to the Alola region before dipping back into Pokémon Bank. See below for a helpful infographic of how the app will work with the new and older games.
