Players will soon be able to link Pokemon Legends: Z-A with Pokemon HOME, allowing Pokémon from their in game team to be transferred into the cloud service. Once stored in HOME, select Pokémon from past compatible titles can also be brought into Pokémon Legends: Z-A, expanding cross game connectivity. The update continues the franchise’s push toward a more unified ecosystem, giving Trainers greater flexibility in building teams across generations and preserving longtime partners for new adventures.
