Ash’s Shalour City Gym battle against Korrina is under way! The battle begins as Ash’s Hawlucha faces off against Korrina’s Mienfoo. He tries to use the rhythmic battle style he learned from Tierno, but it’s not going so well. Finally, he remembers Serena’s observation that he has his own unique style, and decides to battle like himself instead!

With this change of tactics, Hawlucha wins. Ash then sends in Fletchinder, who quickly takes down Korrina’s Machoke. The Gym Leader has just one Pokémon left, and of course it’s her partner Lucario, who Mega Evolves and knocks out Fletchinder and then Hawlucha in short order. But our hero’s unique battling style shines, and in the final matchup, Pikachu defeats Mega Lucario!

Ash wins the Rumble Badge, and the gang is off to Coumarine City for his next Gym battle!
