Pokemon HOME is a free Mobile App and Nintendo Switch game that uses Cloud storage to store Pokemon. Trainers can store and withdraw Pokemon to be used across Pokemon games. Pokemon from Pokemon Legends: Arceus, Shining Pearl, Brilliant Diamond, Pokemon Sword, and Pokemon Shield can all be transferred to Pokemon HOME and between games.  Pokemon from Pokemon: Let's Go, Pikachu! and Pokemon: Let's Go, Eevee! can only be transferred to Pokemon Sword and Pokemon Shield. However, you won't be able to transfer Pokemon back after being transferred to either Sword or Shield. Pokemon HOME can be connected to Pokemon GO. However, you will only be able to transfer Pokemon to Pokemon Legends: Arceus, Shining Pearl, Brilliant Diamond, Sword, and Shield if the Pokemon has already been registered on the game Pokedex. Do not send Lucky or Shadow Pokemon to Pokemon HOME, as they will lose their special status.
