Not really, we know he got slashed, we know he was weaker back then. We also got shown that Oden was a beast of a man that was praised by roger and wb. The only thing people seem really miffed about is the momo situation but then again, context always matters. We dont know that it was kaidos idea or orochi/the old lady so until then its inconclusive. Now i see some here saying that well why did kaido attack him? Its a war, its not 1vs1 honorable combat. People, especially pirates, are gonna take every advantage they can get to win as fast and as efficiently as possible. Ill direct you to Admiral aokiji saying that an instant of carelessness will cost you your life and or defeat. And it happened as was shown with aokiji and kizaru. Heck even whitebeard snuck on akainu and hit him with an enraged attack. A sneak attack which didnt manage to put him down mind you, whereas kaidos on oden did. The whole situation clearly portrayed Oden as a strong fighter and kaido too, since they seem to have been fighting for a while up until kaido got slashed and then fell down. Overall, i say this chapter should hype up Oden instead of dehyping kaido. After all, nothing that happened there we didnt know already.
