Pokémon Chronicles is a compilation of English-dubbed Pokémon TV specials, including episodes from the Weekly Pokémon Broadcasting Station in Japan, The Legend of Thunder!, and Pikachu's Winter Vacation shorts. Each episode delves into the lives of familiar characters like Sakura, Misty, her sisters, Casey, and Tracey whom Ash Ketchum encountered during his adventures. While Ash makes occasional brief appearances, the focus remains on these secondary characters.
