Ur depending on oda knowing about the painting and then going in that exact direction to reference it
Idk just seems like u guys are stretching it and not prepping for the most likely conclusion
But I may be wrong
If big mom and kaido were healthy I'd agree I think they could survive but when's someone's will to fight is beaten in one piece they can be killed by mundane things
The health of your body and mind contribute to one's defense in this universe
Oda does seem to ve knowledgeable and different history, legends, and myths from around the world.
You are still overlooking Kaido and Big Mom durability. It won't just go away because they were defeated.
Who said they no longer have the will to fight. Kaido has lost seven other times so this is nothing new. Kaido could be disappointed because Luffy couldn't kill him like when the Scabbards failed to kill him.
We still have to look at the possibility of awakening. It would be very strange for two Yonko to be permanently defeated and never use awakening. Especially when one talked about awakening and told us what it is.
