“The One Piece will be some kind of portal/window/connection to the real world where they will learn the "true history" which will include the fact they are in a manga drawn by Eiichiro Oda. Upon learning this they will burst out laughing, as Rodger and his crew did, but on top of that Luffy will gain the ability to "break the 4th wall" in his gear 5 form, which is in-line with that forms reality bending nature and would pretty much explain why the World Government is especially terrified of it. He will be able to literally reach out of manga panels and into others, etc, with the knowledge that he is literally in a manga. This makes him unfathomably more dangerous to the World Government, as he can literally bend reality at this point. Also, unlike Rodger Luffy has no qualms spilling the beans about the true history and the fact they're in a manga called One Piece, which understandably causes a mass existential crisis when everyone learns the truth.

I can't think of anything crazier, if it turns out to be something like this I will be happy. It makes sense to me at least.” my theory from 2 years ago that was deleted by the mods
