Just wondering if anyone has had/heard anynew theories since Dressrosa stated. There is the Doflamingo one where he is blind in his left eye(sorry cant remember the site I heard it from :/ but the evidence was amazing.)
Personally I have one about the one of the three ancient weapons and Noah
I think that the reason Noah was created was to counter Pluton's furry. Since the OP world is mostly water it would be reasonable. Also since the weapons were created it can be assumed that there we counter measures created as well. We have seen the size of Noah and the amount of damage it can withstand during Luffy's battle on board and around it. We know that Noah was a failed attempt to go to the surface, and that Posideons power is needed for it to sail So to counter a ship that can destroy the world (or rather raze it to the ground) some group created something not equal in power but something that can withstand the punishment long enough for Pluton to be destroyed. Because at the end of the day Pluton is just a ship and if you can blast a big enough hole into its hull its going to sink. Now to the other two. Posideon couldnt use its power to destroy Pluton because as Posideon has an army of see kings Pluton has an army of Bananawani. Pluton besides a possiblitiy of a sea stone bottom would need another defence against them besides big cannons. The Promise Joy Boy made to the fishman was that he would see to it that humans never came down to the island again, but it was broken when Joy Boy told them that he had no power to stop humans from coming down(told after the project was complete.) The other part was that if no humans came down again they would allow the sea kings to pull the Noah. Finally, Besdies for defencive purposes the sheer size of the Noah is due to it not being meant to be used by humans. We have seen the fishman and their size comparisons so they would need a massive ship if they carried an army inside of it. And Due to the fact that Posideon is a fishman they wouldn't allow there sea kings to be used as meer tools for humans
Just a little idea what do you all think?
