[Theory] How I believe the battle with Kaido will go.

[tyltyl]

Kaido being obviously strong will best Luffy to the point of death. Law will revive him not using the immortality surgery but another. That brings the dead back to life but fully. Luffy will be enraged and go into gear 5th. And get Kaido to a weakened state.(as well as Luffy during the battle) No one knows anything about Gecko Moria. I think he will show up to help take down kaido. By removing his shadow and his body disentagrates by the sun but not completely. The sun goes down but without kaido's arms or legs etc... Blackbeard will arrive then demonstrates how he can take a devil fruit's powers away. (Luffy and everyone else is weakend from the fight and can do nothing.) Allowing him to gain The strongest Logia, Paramecia, and ZOAN devil fruit powers as he is the likeliest last main villain.

I agree with the Blackbeard theory

 

[Rikudou Tobi]

Gear 5? He needs to control his devil fruit better before he can think about another gear.

Mmmm that doesnt look like a plan from Law. I think Law had an idea to how to do it.

It seems I've got a lot of catching up to do, I haven't read the manga since the end of fishmen Island.
