The difference is Kaido was hitting him, whereas Luffy just got hit by an air wave from Warcury's roar thus the gag effect of having his body parts blown off, even his scar lmao.
Bro coc raor IS an attack. Like, is zoro using air slashes not an attack?
This is headcanon, they were next to each other and they too reacted to the wind attack.
As i said, it was targeted to goofy. cause nika is the main enemy.
you remember shanks wifi acoc against GB?
His own fodder crew members lost consciousness, and goofy and co also felt the coc. But only GB was targeted and affected like that. none of the goofy team or scabbards and momo were affected like GB.
same shit. goofy was the target, so it affected him much more.
and also, giants big. so air wave less effect.
Where do you get endurance from? Or ACoC? We dont even know if they have actual fruits by the way because their entrance was super fishy. Oda only showed their Yokai name and not the name of the fruit. As for him hurting Luffy its base Luffy using ACoA lmao. Apoo would hurt him.
it's not goofy getting attacked. Its goofy ATTACKING someone else and that hurting his own damn hands. apoo would get fucked by a red roc lol.
kaido, a damn yonko, got rocked to the ground from that attack from a weaker goofy.
But Topman no-sold it.
Infact, the only time we've seen someone hurting from ATTACKING someone else with haki is...
Katakuri vs goofy. goofy's hands hurt the same as against Topman.
So, it's fair to say that Katakuri is above yonko level and equal to the strongest gorosei
