Pokémon: Battle Frontier is the ninth season of the Pokémon anime and the fourth & final season of the Advanced Generation English-language dub, consisting of episodes 146-192 of the original Pocket Monsters Advanced Generation series. It follows Ash Ketchum as he continues to collect Symbols from the Kanto Battle Frontier while May participates in Pokémon Contests. It began with Fear Factor Phony, which originally aired on September 8, 2006 in the United States, and ended with Home is Where the Start Is!, which originally aired on March 3, 2007.

It originally aired in the United States as part of the 2006-2007 Cartoon Network Saturday morning line-up. The English dub underwent many changes at the start of the season. 4Kids Entertainment's licensing rights to the dub expired and in an agreement with Pokémon USA they decided not to renew. Meanwhile, Kids' WB! (a broadcast network) dropped all anime from its lineup leading to Cartoon Network (a cable network) picking up the series, where it remained until season 19. It began broadcasting on CITV/Action Stations! on October 30, 2008 in the UK, this is the first time this series has been shown on Freeview.

It is preceded by Pokémon: Advanced Battle and is succeeded by Pokémon: Diamond and Pearl, the first season of the dub of the Diamond & Pearl series, which is based on the Generation IV games.


The territory might be familiar, but even Ash and Brock can find more than a few surprises in their home region of Kanto, like a Pokémon Ranger hot on the cases of two Legendary Pokémon! May’s back on the Contest path, blazing a trail to the Kanto Grand Festival, while Ash seeks out the hidden facilities of the Battle Frontier. If finding them wasn’t hard enough, he’s still got battles with the Frontier Brains to deal with—much tougher than any Gym Leader he’s ever faced.
