Since its Oda, he will make look as weak as possible compared to him due to being female. I was impressed he gave us that much with her vs him tbh. I expected her Zoan and hybrid form to potenially be bigger but he insisted on having Kaido dwarf over her and thus impose over her all this time until now.
Given she is his daughter she should truly be an unstoppable force, especially since she seems to "just as much Oni" as he is? Except in size I guess?
But yeah that is ironic she is effectively Fairy and Ice as you said and thus should be super effective vs Kaido ofc lmao. I really wish we could have seen her fight Jack at least, given their similar ages and to give her more hype, Oda really wasted her imo.
