There is only one Plot Twist that could shock both Parties
It's Zoro beheading Kaido & everyone celebrating & then it's revealed that Kaido survived
I mean, most people predicted that Orochi survived being beheaded & it was so obvious
But what if Oda on purpose gave us this easy predictable scenario so that we make our expectations low & then surprise us with Kaido also surviving being beheaded, after all Oda is the guy who hates to kill his Characters but at same time he definitely wants to draw a Dragon being slayed
However if Oda goes with this Scenario, he will need to bring a good explanation of how Kaido's Powers really work
