King is admiral level minimum , it's 100 certified by the manga that his Durability and Wind attacks are AS LEAST comparable to Kaido
Are you really serious by trying to push this agenda? There is the Yonko Kaido, the "strongest creature", hyped since years, when not even since a decade, someone fodderizing Luffy, Zoro etc. pp.. And now, cause King eat an attack, you try to tell the underling of Kaido is secretly stronger then him? You know this is absolutely nonsense.
I know you try to argue Zoro > Luffy. But then you read the wrong Manga. Zoro will never overcome Luffy. And King wont even be close to Kaido. Like Katakuri is not close to Linlin.
