Do you think Oda is able to give Kid equal representation to Luffy? I don't feel like Oda really focuses on Kid me, I find that he doesn't put him forward enough for someone who must be Luffy's rival.
But the CP0 when made mention of the possible defeat of 2 emperors.
I find the focus much more focused on Kaido than BM personally I really have the feeling that in addition to wanting to take Luffy's head, she came to Wano to take a poneglyph, take a treasure and betray Kaido.
