King was never impressive for me, like others YC1
I only wanted aerial battle but how fight are going lately, i need lower my expectations
King was impressive. He's is the most complete fighter in One Piece. King has speed, physical strength, durability, flight, mobility, CQC, lethality, AP, trickery and his unique Lunarian powers. He forced Zoro to master enma, obtain ACoC Zoro to use his head figure out King's power. That's very impressive.
Zoro is just that strong now. King was hit by a stronger attack than the one that sacrred Kaido. Zoro is in better condition too. This battle is preparing Zoro to kill Kaido.
The only time I would like to see from King is awakening. How Zoan awakening was introduced it's a power they use after they are defeated. If Oda is still following that King has to be defeated first before using awakening.
Regardless, if King has it or not the Beast Pirates are going down. Luffy went from taking a massive L from Kaido to fighting him alone on the rooftop. Kaido is weaking from his other battle and carrying the island. That's just the way it is.
