The realm of One Piece fan theories is a wild place to explore, especially given the recent surge in popularity that the series has enjoyed since the airing of the live-action adaptation on Netflix. Whether it's off-the-wall head canon or reasonable logic, there is a convoluted fan theory regarding virtually every single character in the series and why something is the way it's presented in a piece of media. This is especially true in long-form storytelling mediums like manga, and doubly so for a series as long as One Piece.
