Pokémon the Series: XY Kalos Quest (named simply as Pokémon the Series: XY during production and within the episodes themselves) is the eighteenth season of the English and international dubs of Pokémon the Series, and the second international dub season of Pokémon the Series: XY and XYZ. It features Ash Ketchum, his Pikachu, the two siblings from Lumiose City, Clemont and Bonnie, and his old childhood friend, Serena as they continue their adventures in the Kalos region, catching new Kalos Pokémon, and learning more new secrets of Mega Evolution.
Ash and Pikachu continue their epic journey in the next exciting season of "Pokémon the Series: XY Kalos Quest"! While Ash continues his quest to win eight Gym badges so he can enter the Kalos League, he and his traveling companions will make new friends, forge new rivalries, and, of course, meet some brand-new Pokémon! Serena, with her partner Fennekin and new friend Pancham, will take on the Pokémon Showcase world; Clemont will continue to create inventions and hope some of them are a hit; and Bonnie, as ever, will try to find someone to take care of her big brother![1]
This is the final season directed by Tom Wayland, and the first to be directed by Theresa Bucheister. Bucheister took over in the middle of this season.
"An Undersea Place to Call Home!" was originally set to be included in the 17th season with the dubbed air date of July 5, 2014, however since it was postponed, the dub considers it as part of this season.
Like the subtitles Indigo League and Adventures in the Orange Islands, the XY Kalos Quest subtitle did not exist during the original production (and thus it is not used within any of its episodes) but was invented by the official site and the digital and home video releases. Like the first two subtitles (when the show was only known as nothing more than just Pokémon), it is named differently within the episodes as Pokémon the Series: XY without Kalos Quest mentioned.
