One Piece has been airing since 1999, and the manga has been in print since 1997. This means that fans have had plenty of time to come up with theories about the series. While some theories turned out to be correct, others were debunked. Some would have been cool if they'd happened, while others easily qualify as some of the dumbest One Piece theories out there.
Let's take a look at some of these crazy One Piece theories - and at some that are actually pretty awesome. Fans had a lot of opinions about characters who might have joined the Straw Hat crew. Rebecca might have made a good addition, but Caesar Clown? Not so much. Also, did you know that people used to think that Kaido was a Poneglyph that ate a Devil Fruit?
