Nothing special for Kaido. It's been shown that only Kaido can take this type of attack and keep on going like nothing.
You need special haki to hurt him (CoA or CoC attacks)
Kidd and Law have neither of them, that's why they are fighting Big Mom who by the way has no CoO and can't dodge anything at all.
Well, I think their problem is not that they cant hurt Kaido, they can, perhaps even more effective than Luffy but they used it just once.
One punch from Luffy didnt contribute as much as Law's Gamma Knife or Killer's Sonic Scyther. They would have to spam those like Luffy spams his own attacks for them to accumulate and take noticeable stamina away from Kaido...
All those attacks hurt him and they werent as shallow as those of Scabbards, Killer's attack even went full through.
The only one who wasnt impressive was Kidd but you can say that Kaido also screamed from his slam...
If they used Awakening on Kaido they wouldnt have gotten anywhere just the same since they need to spam it.
Well, I am sure that BM has CoO like Kaido does but they are just not the types who are good combatants but instead two tough sitting ducks... They dont look impressive but their toughness carries them to the top of the One Piece world... And BM seems to be powering up so she may look better but overall, she wont change, she will remain a tough sitting duck.
If that was the case than Law is fucking stupid to use his awakening which spends much more energy when he could only use Gamma Knife. Also his awakening would make no sense since he already had awakening powers with Gamma Knife.
Exactly, Law's and Kidd's Awakening are stupid because they were already capable of the same thing before them.
Law could do the same with Gamma Knife while Kidd could have done the same with Repel.
However, since the fight isnt over, they might show something that makes it worth the huge stamina tax.
