Kyutai Panic Adventure! is a one-episode action special that brings together characters from One Piece, Dragon Ball Z and Astro Boy in a single crossover story. It was one of several interactive crossovers shown at the Odaiba Boken-Oh events, which were held to mark Fuji TV's 45th anniversary. The special has not been released on home video. A follow-up, Kyutai Panic Adventure Returns!, came out the next year.
