During the reunion with their old friend Misty, Ash and co. discover Hanson wants to rule the Togepi Kingdom and the Mirage Kingdom. Can they be able to stop him, and will Misty say good-bye to the Pokémon she cared for so long?
This episode was the third of four in the seventh season to have their Japanese and English air dates one year apart.
Misty's Togetic was the second Pokémon to take so long to evolve. The first was Ash's Cyndaquil, which didn't evolve until near the end of Sinnoh League Victors.
