Kaido’s haki was no where near the level it is now when Oden faced him, and even Scabbards can pierce regular dragon scales easy.
Even Kaido on guard still screams out in pain and it doesn’t help that he typically prefers to tank attacks. Shanks as a swordsman has a top tier blade and is actively blocking and parrying, Blackbeard slicing him is nothing to scuff at and is absolutely comparable to Oden overpowering Kaido and scarring him
Shanks today like Kaido is closer to WB and Roger, back then they were in same league. Whitebeard even says Shanks and Mihawk were legendary then when they fought. Same WB never went to Wano because Kaido was also strong and had a country backing him
kaido rarely ever used haki to guard himself so that besides the point personally.
Pls do not compare the scabbards piercing kaido's scales to the scar . kaido himself laughed them off and their cheap imitation of oden. Massive difference there
"shanks as a swordsman has a top tier blade and is actively blocking and parrying, Blackbeard slicing him is nothing to scuff at and is absolutely comparable to Oden overpowering Kaido and scarring him"
seen enough fights in one piece to know being on guard doesn't have to mean they attempt to block or parry an incoming attack.
"Shanks today like Kaido is closer to WB and Roger, back then they were in same league. Whitebeard even says Shanks and Mihawk were legendary then when they fought. Same WB never went to Wano because Kaido was also strong and had a country backing him"
not sure why this is relevant ..
its not about what league or tiers they are in
kaido's defenses even when others have strong haki is just vastly superior.
its no slight at BB, oden's feat is more impressive. oden scarred kaido like that at the peak of his power as a top tier, BB was still growing potentially as a commander in Wb's fleet.
