About

Open a save from the main series games, from Red and Blue through Legends: Z-A, and change Pokémon, boxes, the party, items and trainer details. Each Pokémon gets a legality check, so you can spot problems before you save. Game-specific editors cover Pokédex progress, events, raids, fashion, mystery gifts and more. Changes stay in the app until you save, and the previous file is backed up automatically. PKHeX-Avalonia is a fan project built on the PKHeX engine. It is not affiliated with Nintendo, Game Freak or The Pokémon Company.
