The Y-Comm (Japanese: YY通信 YY Communication) is a feature introduced in Generation VIII which is used for trading Pokémon and Link Battles over local wireless or on the internet through Nintendo Switch Online. It is the successor to the C-Gear, Player Search System, and Festival Plaza interfaces from previous games. It is enabled once the player has obtained the Dynamax Band. It cannot be used when the player is challenging a Gym.
