Pokémon the Series: Diamond and Pearl

After participating in the Johto League, Ash decides to begin anew in yet another journey; this time by himself and Pikachu, in the land of Hoenn. Though he isn't alone for long, as 10-year-old May (who dislikes Pokemon, but just wants to come along to see the world) travels with him after Pikachu destroys her bicycle. Ash also meets up with his old companion, Brock, and May's younger brother, Max. Together, they travel along in Hoenn, battling Gym Leaders, entering Contests, and other events on the way to the Hoenn League.

A young boy named Satoshi embarks on a journey to become a "Pokémon Master" with his first Pokémon, Pikachu. Joining him on his travels are Takeshi, a girl-obsessed Rock Pokemon Trainer, and Kasumi, a tomboyish Water Pokémon Trainer who may have a crush on him. Satoshi and Co. end up traveling through various regions, including Kanto, the Orange Islands, and Johto, and then enter the Pokémon League competitions there. Along the way, they run into many confrontations with Musashi, Kojirou, and Nyarth, a trio of Pokémon thieves who are apart of an evil organization called "Team Rocket". But everytime Team Rocket try to do their evil deeds, they fail thanks to Satoshi and his Pokémon.

As with both the Advanced Generation and Diamond & Pearl series before it, the Best Wishes! series begins with only Ash Ketchum, headed off to the Unova region, located far away from Kanto, Johto, Hoenn and Sinnoh, with his Pikachu. After he meets up with the new trainer and rival Trip and the region's Professor Juniper, he gains traveling companions in Iris, a girl from a town known for its Dragon Pokémon, and Cilan, Pokémon Connoisseur and the Grass Pokémon specialist of the three Straition City Gym Leaders.

After his mom wins a free vacation trip, Satoshi and Pikachu are off on another adventure. This time in the tropical land of Alola. There they meet new friends, Pokémon and explore new islands. We also get introduced to Z-Rings, a device used for Z-Moves. What kind of mysterious Pokémon and challenges will come their way, and why is Kapu-Kokeko so interested in our young trainer?!
