joy boy was domi reversied ?
i theorize that at the end of the first war joy boy got domi reversied by imu. wich is how he lost. now we know that nika is known by god of laughing, god of liberation. but actually some giant see him as the god of war, or god of destruction. this would explain why some of the giant kids was afraid of him, when killingham pulled out a nika from the kids nightmares we can see how much darker this nika is compared to normal nika. also the sharp teeth. kinda look like a domi reversied nika. this image of nika has also been presrved in the culture, wich is why there is two diffrent iterations of him.
when somone gets domi reversied they grow drasticaly in size. including clothes and wepons. because of the emeth flashbacks i believe he was already pretty tall. like doffy or whitebeard. beacuse i think he was still a human just massive. and then grew to giant size cuz of DR. it would explain the giant sized straw hat at marie J. that would be the only explanation for what it is for now. beacuse we know its important, why would they lock it up then???
