both KKG and Togen totsuka knocked kaido to the ground
the difference is that current Kaido has awakened his DF and used awakening to recover from the attack
^^ this isn't his normal hybrid form
Yes, Oden did nearly kill Kaido. That's why Kaido ranks him as highly as he does, despite Oda showing us that he wasn't on the level of WB or Roger. The thing was, Kaido simply wasn't as strong as he is right now, 20 years ago.
