As expected with a manga like One Piece there are numerous theories and speculations that have been made over the overall story, future arcs, characters' backgrounds and connections with other characters, etc...
Of course most of these theories end up debunked or are simply ignored as if they never existed as the story progresses.
Among these theories which ones did really catch your attention because of how well-made and interesting they are but didn't happen in the canon story ?
One example I remember is a theory that Doflamingo poisonned Whitebeard as the medicaments that were used to calm and treat Whitebeard's sickness had the Donquixote Family logo on them and that it was one of the reasons why Whitebeard was so sick during Marineford arc.
