Hansel and Gretel of fairy tale fame — now acting as secret agents — must use magic, clever thinking and teamwork on a mission to find a missing king.

This is the story of how Ash and Pikachu first met. At first, Pikachu was disobedient towards Ash, but Ash only wanted to be friends with Pikachu. On the day they set out from Pallet Town, both of them saw a Ho-Oh flying and they made a vow to meet it.

In this Pokémon adventure, a mysterious force binds Ash to the Mythical Pokémon Volcanion when it falls from the sky. Volcanion can’t get away, and Ash is dragged along as it continues on its mission. They arrive in a city of cogs and gears, where a corrupt minister has stolen the ultimate invention: the Artificial Pokémon Magearna, created 500 years ago. The minister plans to use Magearna’s mysterious power to take control of the mechanical kingdom. Can Ash and Volcanion work together to rescue Magearna? One of the greatest battles in Pokémon history is about to unfold!
