A Pokémon League is the top-level tournament of Pokémon Trainers who compete in Pokémon Battles toward beating increasingly higher-ranked Trainers. To enter, one must collect eight badges, one from each Gym in their regional area. Also, they are only allowed to use six Pokémon at a time, both in the games and the anime. However, unlike in the games where a Trainer only works toward the goal of eventually battling the top victors, called the "Elite Four," in the anime, Trainers must participate in a tournament where they battle one another in order to win.
