King should never exist in the first place. Or just not Zoro fighting him.
Bro, Zoro wants to be WSS, land of swordsmen and no actual development towards his goal.
His biggest fight in the entire series is a Ptero Karate Kid with no advanced Haki forms and he also tells Zoro "fuck swordsmanship who cares"
Orochi should never exist. It should've been Nobunaga, he should be on par or slightly weaker than Kaido, Kaido would hype him up vs Luffy making Luffy fear for the alliance since there is another Top Tier on Wano on the opposing side, Zoro fights him and gets the biggest challenge in his path prior to Mihawk.
Nobunaga shows Zoro his remaining flaws and Zoro has to overcome them in an attempt to beat him. The ending of the fight is Zoro understanding that he can support Luffy by becoming a King in the Shadows ( a nod to Rayleigh's portrayal and title ) he awakens advanced CoC and surpasses Nobunaga.
Why did I write all of that ffs. As if Oda would do it.
