I can understand Kaido not having Awakening but what about Big Mom, Law and Kidd lol?
I guess for Big Mom that she takes away souls? Not sure what's the purpose of the Soul Soul fruit supposed to be, maybe creating an environment where everybody (souls) can live in? But that's literally what Big Mom trying to do, except that there's no souls part involved.
Law, he's a surgeon so I guess he matches Ope's mind criteria.
Kidd, just for fixing some metal junks lol?
