Ash and Goh arrive in the Kalos region, where Goh wants to catch new Pokémon, while Ash wants to raise his World Coronation Series ranking by competing in the Battle Festival Challenge!
Ash discovers that his friend Korrina, the Gym Leader of Shalour City, is also competing with her partner Lucario. Both Trainers are one win away from ranking up to the Great Class, so they decide to have a battle! Korrina’s Lucario defeats Ash’s Gengar, but when Ash sends out Dragonite, an unusual strategy takes shape. Even through Lucario Mega Evolves, one final attack gives Ash the win—and a spot in the Great Class!
