Does Hyogoro have seimei kikan? That would explain his sudden buff bod and also how he was able to digest and absorb food like Kumadori. Wait a min Luffy can do that to. Luffy has shown the ability to instantly digest and absorb vast quantities of food on several different occasions. What if Hyo noticed this and thought Luffy other uses of seimei kikan. Like Rob Lucci's life return. Luffy goes into gear 4 inflates all of his limps into kingkong size uses life return to compact all of that power into a neat little package. Gear 5th?
