Zoro cut him and made him cough up blood
The whole point of Zoro's attack
was to save Luffy's life and make Kaido cough him up. Yes it did damage of course.
Where did I say otherwise? I was merely saying that two other SNs did a similar level of damage.
Law cut his heart and made him
scream out in pain and shock. Kaido
went straight back to attacking, so it's hard to fairly quantify Zoro's attack as being a tier above in damage and unfair to say Law and Killer haven't done shit, Zoro is above them and below Luffy so far in overall damage, Kidd is fucking up though.
