This is a list of episodes in Pokémon: Diamond and Pearl: Battle Dimension aka Pokémon: DP Battle Dimension, aired in Japan as Pocket Monsters Diamond & Pearl (ポケットモンスター ダイヤモンド&パール, Poketto Monsutā Daiyamondo & Pāru?), the eleventh season of the Pokémon animated series, covering the continuing adventures of Diamond and Pearl series protagonist Ash Ketchum as he continues to travel Sinnoh with Dawn, Pikachu, and Brock. The division between seasons of Pokémon is based on the English version openings of each episode, and may not reflect the actual production season. The English episode numbers are based on their first airing in the United States either in syndication on Cartoon Network, or in Canada on the YTV Television Network. Other English-speaking nations largely followed either this order or the Japanese order. Subsequent airings of the English version follow the original Japanese order, except in the case of episodes which are no longer shown in English. This season began regularly airing in the United States on April 12, 2008 and ended on May 2, 2009, with a total of 52 episodes dubbed in English. This is also the first season to have DuArt Film and Video produce the English version of the Pokémon anime series in general (due to TAJ Studios disbanding), and the first to have a new voice director (Tom Wayland) who has also done work for 4Kids Entertainment, as well as a first to have 4Kids related actors in guest starring roles on the show since Season 8 of the series. This is the last season in the anime to dubbed with voice-over by Media Link.
