The Pokémon League consists of four Elite Four members and the Champion. You must defeat all five in a row without healing at a Pokémon Center. Make sure your team is fully healed and stocked with Potions, Revives, and status-healing items. The Elite Four members are:

- Aaron (Bug-type): Uses Bug-type Pokémon like Yanmega, Heracross, Vespiquen. Weak to Fire, Flying, Rock.
- Bertha (Ground-type): Uses Ground-type Pokémon like Whiscash, Hippowdon, Rhyperior. Weak to Water, Grass, Ice.
- Flint (Fire-type): Uses Fire-type Pokémon like Rapidash, Infernape, Magmortar. Weak to Water, Ground, Rock.
- Lucian (Psychic-type): Uses Psychic-type Pokémon like Bronzong, Alakazam, Gallade. Weak to Bug, Ghost, Dark.
After defeating the Elite Four, you'll face the Champion, Cynthia. Her team is diverse and powerful, consisting of Spiritomb, Roserade, Lucario, Milotic, Garchomp, and Togekiss. Garchomp is particularly dangerous. Have a well-balanced team with good type coverage. After defeating Cynthia, you will be crowned the Pokémon League Champion!
