Soo Kaido knows about Joy Boy hmm, pehaps Rocks and his crew knew much more about the Void Century them we think, and Kaido seems to think that Rocks and Roger weren't able to "become" Joy Boy. The Rocks FB probably will show a lot about this search for the truth the WG hide, pehaps Rocks even knew about Imu.
High hints on Momo being Uranus. His powers will show up and save him from Kaido in the next chapters, what would make Kaido and BM want him ever more for he being a Ancient Weapon. Wonder if his powers are the thing that make him able to control Zunesha, and if it is the only thing he can control, and what will be Zunesha role in the Final War. Pehaps is to lift Luffy allies from the NW to Marijoa.
And i wanna know too, if he really is Uranus, if his powers are something that he only have, or that the main heir of Kozuki clan always have, so Oden, Sukiyaki and all the heads of the Kozukis since the Void Century would have this same powers, and that was the thing the Kozuki clan wanna protect from the WG by closing the country, and the reason why Toki send Momo to 20y in the future, to the time of JoyBoy/Luffy.
Hope Ashura, Kiku, Kanjuro and Kinemon are all dead, would put some of the drama the Arc is lacking soo much.
