About Kaido and Big Mom...
So many people have been asking around whether they are alive or dead.
My personal opinion / theory is: Kaido is dead, Big Mom is alive. I thought about some points that make sense to me to have that theory be true.
If Kaido was alive, then Wano would definitely be doomed again. If he somewhat recovers from his injuries, he could easily take Wano back (remember, there are still beast pirates there so some might definitely re-join Kaido. And depending on what Aramaki exactly did to King and Queen, he would have his All Stars back). So if he was alive, he would torch the entire country and everything would have been in vain kinda. So that's why my theory is that he is actually dead. Plus he kinda got what he wanted, to die a memorable death in a fight. So it would make sense for his story to be definitely over.
BM on the other hand: given how easily she holds grudges (especially against luffy since Fishman Island and her ruined wedding cake), she will most likely ignore Wano if she was still alive and go straigth after Luffy, Law or Kid. She will most likely catch up to them in Elbaf (as it would kinda make sense to connect BM to the giants again in the story). She might have survived by either (i read that in another comment or post which i can't remember from where sadly) taking Kaido's remaining life span as he is weak after his fight, or Prometheus somehow reached her and stored her inside him to shield her against the Lava heat with his own heat.
How she would know that she would need to go to Elbaf? I think there are 2 possibilities:
- If she wants to go after Law, she hears about Law's defeat against BB. She assumes that BB has Law and tries to find them and will follow the BB ship that appeared at Egghead as it might be possible that it will follow the straw hats to Elbaf.
- If the wants to go after Luffy (since he started the whole mess), she might still have some sort of soul connection to Zeus so she would have a pseudo log pose or a vivre card to Zeus. Since she knows Zeus betrayed her and joined Nami, she definitely knows that Zeus' location is where Luffy is.
Of course we don't know for sure until Oda confirms anything but i think narratively for me personally it would make sense if it was like that.
So yeah in short:
Kaido dead, because if he wasn't he would torch and take back Wano instantly.
Big Mom alive, she will go to Elbaf after Luffy (+ we get some more connections with her and the giants).
Or what do you guys think?
