Base CoC doesn't even have anything to do with power lmao.
King has far better feat than Kat in every regards other than CoO, and that's all he needs to outclass him. Your logic is about as retarded as trying to say Doffy > Marco because Marco hasn't shown awakening.
Btw, King is yet to even go Hybrid and he's outclassing KK best feats.
Also, ofc, King blocks with his wings. Those are the durable part of his body. Kaido can only block with his scales which are already cleaved by an attack far weaker than SSSS... what do you expect him to do other than that?
I'm not pretending he's close to Kaido. Overall, Kaido is tier apart, but you're being about as daft and agenda driven as people who say King > Kaido when you're pretending King doesn't stand significantly above Katakuri at this point.
