Ash and Iris arrive in Striaton City, the location of Unova's first gym. When they arrive in town they meet a boy named Cilan who says he is a Pokémon Sommelier, someone who is able to test the compatibility between a Pokémon and trainer. He leads them to the Gym where it is revealed that he and his two brothers are all the Gym Leaders of Striaton City. Will Ash be able to defeat the three brothers and win his first badge?
A young boy named Ash Ketchum embarks on a journey to become a "Pokemon Master" with his first Pokemon, Pikachu. Joining him on his travels are Brock, a girl-obsessed Rock Pokemon Trainer, and Misty, a tomboyish Water Pokemon Trainer who may have a crush on him. Ash and Co. end up traveling through various regions, including Kanto, the Orange Islands, and Johto, and then enter the Pokemon League competitions there.
Along the way, they run into many confrontations with Jessie, James, and Meowth, a trio of Pokemon thieves who are apart of an evil organization called "Team Rocket". But every time Team Rocket try to do their evil deeds, they fail thanks to Ash and his Pokemon.
