I don't know if this has been discussed because I just found this place recently. I'd like to talk about the ancient weapons. They will obviously play a large role in the future. As many of you probably agree, there will probably be another enormous battle similar to Marineford (even if it isn't a rescue mission.) consisting of pirates, marines, revolutionaries, etc. I believe that during this battle, we will see the use of the ancient weapons. Franky had the blueprints for Pluton, and we see him burn them during Ennies Lobby. Is it possible that Franky could have memorized these blueprints? Not only is Franky intelligent, but he could've had some strange cyborg parts allowing him to memorize the blueprints. I know this idea is a long shot. We have no evidence that Franky did memorize the blueprints, and sunny is clearly intended to be the Straw Hats' ship. What do you guys think? Shirahoshi was also revealed to be an ancient weapon. She clearly favors the Straw Hats, and I believe she would assist them in this battle. I have seen multiple theories talking about going back to Marineford, and I'm pretty sure this will happen. Luffy promised to take Shirahoshi to a real forest, and for that reason I doubt she would ever go far from her home to seek out the Straw Hats. If they do go back to Marineford, I believe Shirahoshi will race to their aid. These are just ideas, and I would be happy to discuss them with anyone interested.
