XY002: "Mega Evolution and the Prism Tower!"
Ash arrives in Lumiose City to begin a new journey in the Kalos region, and meets Clemont and his sister Bonnie. A battle between Ash and Clemont is cut short when Team Rocket interfere, until a mysterious Froakie intervenes.
Weak from its battle with Team Rocket, Ash finds care for Froakie at Professor Sycamore's lab, where the Professor is researching Mega Evolution. But Team Rocket's mischief causes a Garchomp test subject to go berserk.
