Oden was grouped together with Roger, he had a better sword style than Roger, he literally had Kaido’s kryptonite built into his Haki, unless of course you’d like to explain to me why DR Xebec’s attacks didn’t leave a scar on Kaido but Oden’s did. And on top of that, Oden is physically a monster (portrayed as a freak of nature), and nothing suggests Oden’s Haki is inferior to Roger’s — if anything, based on how he was portrayed, it’s at least equal. And even with all that, he was getting beat up by Kaido in his dragon form. LMAO
