Nanako "Casey"

Over the years, Ash Ketchum (Satoshi) has traveled to many different regions in the Pokemon world. Each new region brings a new generation of Pokemon with it and the anime features Ash and his pal Pikachu catching a new team of Pokemon with each new adventure.

Pokemon has always featured Satoshi (Ash) challenging Gyms to win badges and enter the Pokemon League. But Gym battles are not the only path open to a Pokemon trainer. Aspiring, young trainers can also work hard to win Showcases, Contests, and a number of other events with their Pokemon partners.
