Nintendo has made Pokemon HOME available now for the Nintendo Switch and first-time users are granted a level 5 Pikachu.

HOME is a cloud service designed as a hub where all Pokémon are gathered. By linking the same Nintendo Account to both the Nintendo Switch version and mobile version of Pokémon HOME, players can access the same Pokémon Boxes on both versions. Pokemon HOME allows users to move and trade Pokemon between compatible games.
