One piece; Katakuri vs King, who will win

 here we have a showdown between the commanders of different yonko. katakuri vs king is one of the most interesting matchups I've seen in a long time. both are known to be extremely powerful. but if you compare them or place them in a death match who will emerge victoriously.

  

in a one-on-one match katakuri has a greater chance of winning. one might day that king has the highest known bounty for someone who hasn't held the captain title, and that is true but when you compare feats katakuri has outclassed king.

first of all, katakuri has a far more durable devil fruit(mochi mochi no mi) that can cover a large scale and can be used in various kinds of ways. King, on the other hand, uses (Ryu Ryu no mi) a devil fruit which allows him the power of a pteranodon it is an ancient zoan devil fruit and holds lots of power but it's still little compared to the mochi power as it differs in range and effectiveness.

also, it is obvious that katakuri is a lot better at conservation haki, imagine training observation haki to an extent whereby you can see the future, not even big mom or Kaido has trained their haki to that level and surely we know that king cannot use future sight.

conquerors haki is the haki of the Supremeking, it is the rarest form of haki in the one piece verse and unlike the other forms of haki ( armament and observation haki), conquerors haki cannot be learned it is only possessed by a selected few born with this innate ability of a king 👑. yet, Katakuri possesses this kind of haki, he also possesses strong armament haki, if you put all these abilities together you'll find him to be stronger than king. 

though King hasn't fully been dealt on yet, he hasn't displayed any feats worthy of fans' attention and it is most unlikely that he'll be able to use conquerors haki.

Winner: katakuri
