Zoro molests King.
Nothing King has done suggests that:
- He can overwhelm Dragon Kaido's Tatsumaki
- His offensive prowess is so great that Kaido would dodge his attack
- He can (momentarily) block a top tier (combination) attack from Hybrid Kaido and Prometheus fused Mama.
By current feats and portrayal, King is not even on the same playing field as Zoro. Or at the very least, if King can actually match Zoro, then he's significantly above the likes of Katakuri and Marco. Zoro is significantly above the likes of Katakuri and Marco.
I honestly wouldn't go as far as to say that.. to zoro's feats are admirable.. you can give zoro the courtesy that he does beat king in a 1v1... that would still be high-extreme diff but we haven't seen crap from king except for trying to cut marco which provides minimal evidence that he would just be fodder to zoro so that inconclusive
Marco is above YC1 and was a candidate for the seat of a Yonko tho u can said he got throttled by BM.. its just to say that nothing like that has happened to zoro yet and nothing proves as evidence that zoro can force out his way from BM's fists but well Kid just did that and I'm gobsmacked , marco has tanked attacks that admirals use against Yonko's like the laser beams from kizaru that he used against WB, and came out of the war with no fatal damage even tho he led the vanguard of the war.
And zoro blocking a top tier attack is something you'd expect from a YC 1 even if momentarily it was at a cost an admirable sacrifice, He did cut Kaido with that tatsumaki which even kaido recognized... so the moment he masters enma he would grow exponentially since his offense comes from the oddity of the blade which no other blade provides.
Katakuri on the other hand bruh, is no pushover, he's got better ARNAMENT, better Observation... and durability and endurance over gear 4... the odds stack against zoro with this one.. and the only reason why i conclude that zoro will win against King coz it has been a Hypothetical matchup and king's less showings.. but we also have take their portrayal as second in command in account... they shouldn't be pushover by any means
