Ash is training fiercely for his upcoming Masters Eight entrance battle against Raihan, and when he sees Goh’s Froakie evolve into Frogadier, he gets an idea! Realizing that his friendship with Lucario is similar to the bond he shares with Greninja, he and Goh travel to Kalos. They find Greninja, who runs circles around Lucario in battle, but eventually Lucario learns how to focus its Aura powers and connect with Ash on a closer level. And when gigantic roots attack, the Pokémon show their strengths and defeat them together! With Lucario boasting newfound strength, Greninja once again departs—but Ash knows they’ll always be close despite being regions apart!
