Jack still need extreme diff fight so they are close. If Jack is way stronger than Inuarashi then why couldn't he defeat Inuarashi in day 1?
It wouldn't be an extreme diff fight. Your overall level is every stat and ability you have, Jack's endurance and durability makes up for his relatively minor attack power that he's shown. He's resilient, that's what Oda's emphasized with him. Five days of non-stop combat against a nation of natural born warriors stresses this.
Within the first 12 hours Inuarashi is panting. I really doubt he'd last a full day if he's already exhausted himself like that. Which is how Jack seems to win against strong people, outlasting them.
Sorry this is baseless. You have no proof Denjiro statement is false. It was Oda who made Denjiro says that.
...And it was Oda who made Denjiro immediately shocked that the Mid Trio could beat the fodder in the castle lmfao. It was a hype moment for the Straw Hats, no different than Fishman Island's conclusion where they all showed off.
According to you Jack is YC3 that's why I said Ashura Doji and Inuarashi are YC3.5. The fact that Denjiro thought scabbard with Ashura and Inuarashi would have difficulty destroying fortress while casual SH did it easily implies that Ashura and Inuarashi might be YC4 which makes Jack YC4 power level wise.
So, Jack without his DF was fighting evenly with Ashura after the initial attack. Ashura and Inuarashi were highlighted as equals. Logically, Jack in Hybrid >> Jack without his devil fruit. So, yes. YC4 for them sounds appropriate.
Lmao how? Another baseless assumption. Based on what? There is still Ace card so by that logic King is not the strongest calamity.
Ace can be the highest or the lowest card. Its existence, should it be a thing, means absolutely nothing. Out of the shown characters, out of their bounties compared to the Sweet Commanders and how Oda presented them, this is the easiest conclusion without leaping to conclusions. Queen and King mirror Sanji and Zoro, the top 2 under Luffy. Ergo, they are the top two under Kaido as well.
