If Gary Oak is headed to the Sinnoh region, Ash Ketchum won't be far behind! Ready to take on a new challenge, Ash and Pikachu meet up with Brock in Sinnoh, where they're joined by Dawn, a novice Pokémon Coordinator determined to follow in her mother's footsteps. They struggle with their respective paths, but it's easy for them to make new friends, gaining new Pokémon like Turtwig and Piplup.
While Ash, Pikachu, and Aipom head toward the Sinnoh region, where lots of new adventures await them, a young Trainer named Dawn is just beginning her own Pokémon journey.
As Dawn sets off to find an injured Pikachu's Trainer, Ash hears the story from Professor Rowan and sets off to find Dawn-and reunites with Brock along the way!
After Team Rocket makes off with Ash's Pikachu once again, a feisty Turtwig appears to rescue Pikachu and later takes a bit of time to warm up to our heroes.
After showing up again seemingly out of nowhere, Paul is pitted against Ash in a series of battles that reflect just how different they are as Trainers and people.
