How do you get mantaphy?

To obtain Manaphy in Pokémon games, you typically need to transfer it from Pokémon Ranger, where it is originally obtainable. In Pokémon Ranger, players complete a specific mission to receive an egg that hatches into Manaphy. In some games, like Pokémon SWord and Shield, you may also find Manaphy through special events or distributions. Always check the specific game and generation for the precise method, as it can vary.
