No, it's not. There is no denying Big Mom is leagues above King. But she was utterly incompetent in this fight. Based on her and their performances, beating King isn't any less an accomplishment. Does this mean I think King is close to BM? No, she stomps him, just so we're clear.
Don't be so insecure. I did not say King is as strong as Big Mom. I said beating King in a one-on-one can be as big an accomplishment as beating BM in a two-on-one meaning their individual contribution could be comparable to Zoro's overall contribution. Btw, did you see Big Mom's strongest attack is just as good as King's Dragon that he used on fodders? I wonder which one is more fearless according to you.
There wasn't a single instance where I put Oden anywhere near YC1s. Don't steep so low that you'd use lies to demean others—that's honestly sickening.
How many of them can damage King though? And let's not gift Kaido's feats to Big Mom. Kaido blitzed Law 5 seconds into the fight and had him on the ground.
