zoro has a lot of haki, it's insane.
he's not even going all out, yet he can easily infuse a dragon sized amount of haki into a single sword for a single attack.
completely overpowered kaido's little twisters (which overpowered both kid and killer), and dealt massive external and internal damage.
tatsumaki is literally nothing compared to the rest of zoro's attacks, a basic fodder sweeper that he can do without even wielding a sword, but it was powerful enough to embarrass a yonko.
all these scrubs going all out can do nothing to kaido's scales.
zoro with a basic attack, puts them all to shame.
my GOAT.
