Sengoku saying Big Mom and Kaido are much stronger now than they used to be?
Oden last words to Kaido telling him to grow much stronger for what will happen in the future?
Oden has the AP to kill Kaido like high tier Zoro had the AP to scar Kaido, don't mean he'll be able to triumph over his prime self assuming Kaido doesn't get PTSDs crisis .
There's absolutely no narrative reason for Luffy (Joy Boy) to come out of Wano weaker than Oden (which would be the case if Oden > Kaido since many have Luffy still inferior to Kaido)
He said that in regards to God Valley. A fight that took place 18 years before the Oden and Kaido fight. (Back when Kaido was 21)
And Kaido took that to mean grow his army. After this he began trading with Doflamingo and amassing weaponry, growing his strength this way. However, Kaido himself never mentions growing stronger since his fight with the oden.
And look, we agreed that the only thing oda is ever consistent power scaling wise is that characters will always match the strength they’re portrayed to be regardless of feats.
And oden was continuously portrayed to be comparable to current Kaido. Kaido himself treated oden as such. I don’t like oden, he’s one of my least favorite characters, but I’m not going to ignore how much Kaido still sucked this man off just because I don’t like him.
