On their way to a safari zone teeming with Pokemon, our heroes walk right into the middle of a jungle. Without knowing they are in a region in which Pokemon are protected, Ash tries to capture a Chansey and is arrested by Jenny, the safari ranger. After talking with the ranger, Ash is released, but not before he learns that there are Pokemon poachers in the area. Our heroes accompany the ranger into the forest, pursuing the poachers. Within the jungle, a young man leads a pack of Kangaskhan. His name is Tommy and no one knows the secret of his childhood.
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.
