If you only watch the anime, you probably shouldn’t read this. This will contain spoilers for chapter 906 and 907. I also said I would post this if something was confirmed in 907. That thing wasn't confirmed, but Oda still delivered something very helpful At first, I was one of the people who was a firm believer that the straw hat was the great secret of Mary Geoise, but then I started to think a little more realistically. The person in the mask went downstairs into some locked room. There is no way the straw hat has great power, if it did you honestly wouldn’t need to lock it way down there. No one in their right mind would believe that the straw hat had this much power, so you could literally hide it in plain sight and not make a big deal about it. I just wanted to make sure you understand that in this theory, I believe that the straw hat itself isn’t important. If you believe it is then there is a thread that talks about it’s possible importance. You should definitely check it out, “The Straw Hat Has A Strong Charisma Boost”, by @Robin-Senpai Is The Best I enjoyed talking in there, if you believe the straw hat is important saturate that page, if not, you should still saturate that page. I didn’t notice it until after Tekking mentioned it in his chapter review, but the surroundings look like they are a part of something that use to be there, this gave me two thoughts one which is a bit more wild than the other and I will definitely elaborate on. 1. I joked about it in a previous thread I called it a magic trick, but maybe the secret is literally under the straw hat. If you think about this like the real world, there are many things that are told to us that we just accept. We believed Columbus found the US, which was obviously not true, yet we still believed and celebrated it, some people still do. Doflamingo said something in chapter 906, “Power has a very short shelf life”, in this theory I’m taking this to mean social power not physical power. We have been constantly told by the world government that the D is the enemy of the of the God, I have no reason to believe this is not true. What if the D isn't the one everyone should be worried about? What if under the straw hat is proof that the people that were meant to stand in power were the D’s? There are 20 kings that left their kingdoms to be to go to Mary Geoise. Correction, 20 were offered and 19 took the offer. The one family that did not take this offer was the Nefertari family. Thinking about it logically, why would anyone not accept this power. It’s simply because they do not agree with what transpired during this void century, and I believe another family didn’t agree either. In chapter 907 I was reminded of Donquixote Homing, Doflamingo’s father. Why did he decide it was time to leave the holy land? I believe every CD is at some point told what happened during the Void century, it’s just some take it different. When Homing found out what happen he couldn’t stay there anymore, he had to get his family out of this area. The reason that the Donquixote family decided to stay in this area in the first place was because they needed someone to fight from within. How did fishman tiger get up into Mary Geoise? I’m assuming people are only let up during reverie, or to let a CD back in. This whole time the Donquixote family has been fighting the government from the inside. The person that went down to see the straw hat was actually a Donquixote, and I believe they are wondering when they will actually be able to revel this secret. They are waiting for the D to return. I don’t know what is under the hat to be honest, but obviously it’s something that cannot be burned as easy as paper and I don’t think it’s an ancient weapon. I believe the thing under the straw hat is something that can’t be broken by sheer power or by devil fruit. I believe it is something that has been kept in writing on a stone of some kind. Maybe sea prism. On this stone it tell of the original rulers, and their benevolence. 2. I just now decided that I will post my other head cannon in a different thread. It will explain how Shanks does what he does. This is the wild one that I wanted to elaborate on, that I can't get to right now. If you finished reading let me know what you think. Is the straw hat important? or is there something else of important? what do you think it is?
