Elite Four

The Elite Four (Japanese: 四天王, Four Heavenly Kings) is a group of four Pokémon Trainers who are regarded as the toughest in their regional Pokémon League, short of the Pokémon League Champion. To challenge the Elite Four, one must have collected eight Gym Badges. Defeating all four Elite Four members allows Trainers to battle the Champion; only by defeating the entirety of the Elite Four and the Champion can Trainers enter the Hall of Fame.

Generation VII
In Pokémon Dawn and Dusk Versions, the player faces two different groups of Elite Four members, each corresponding to his or her place in the games. The first group, which is secretly affiliated with the evil Team Order/Team Kaos, is replaced by the second during the post-game after its treachery is exposed.
