One Piece, also referred to as Shonen Jump's One Piece, is a side-scrolling beat 'em up game for the Game Boy Advance. It is based on the One Piece anime series. Developed by Dimps and published by Bandai America's games division, it was released on September 7, 2005. It is the only One Piece game to be released exclusively in North America, and the first of two to not see a release in Japan. Due to being an American-only title released while 4Kids Entertainment was involved in the dubbing and localization of the anime, there are a few discrepancies compared to the canon material, matching 4Kids' edits and changes of the anime.
