this is the first time we are seeing anyone go seriously at a yonko in their prime so I know folks are disappointed but dont be
kaido will win this anyways .
As for Scabbard and Kaido, I was disappointed that Kinemon and co(those who moved with him in time) are also able to injure Kaido, as well as those who honed their skills these 20 years and became stronger.
20 years ago, Ashura and Denjiro fought Kaido and failed to injure him. Where does this conclusion come from? Because in recent chapters, Kaido was very surprised that Scabbard could injure him. After all, if they had been able to injure him then, he wouldn't be surprised now. I don't know if others will agree with me, but I believe that 20 years ago, the strongest Oden's samurai was Ashura. And if he couldn't, then Kinemon, and even more so Kiku, had no chance of doing so.
From this we can conclude that either Oda made a mistake in the plot, or Kaido had a breakdown like BM.
Or Oda will play the version with the scar from Oden and his Will\Haki.
In general, I am waiting for an explanation from Oda in the future on this issue and I hope he will not leave it unanswered.
