Pokémon : S19 | E46 – Facing the Needs of the Many!

Heading back to Lumiose Airport after saying goodbye to Goodra, Ash and the gang encounter a remnant vine from the attack. Ash and Greninja notice that the vine is being fueled by some kind of energy in the ground. Having taken it out, Xerosic appears and abducts Clemont. Xerosic tries to brainwash Clemont to revive the goals of the now defunct Team Flare, but he fails to do so and ends up arrested by law enforcement. Afterwards, more remnant vines and both Zygarde appear, with Ash releasing Greninja into the care of Zygarde to help restore order to the Kalos region. (Source: Wikipedia)
