Which is irrelevant since what Zoro meant there by "knocking someone out" was this
You know Japanese, look at the raws. Zoro used the exact same verbage as to what Momo used here:
Here's Zoro's words:
Tell me, did Momo want to knock down Kaidou for him killing his mother and father and ruining his nation?
Besides,
Scabbards knocked Kaidou down ---> Couldn't even reopen the old scar.
Ashura didn't knock Kaidou down ---> Gave Kaidou a new scar.
How can you possibly argue for Togen Totsuka > Ashura Dead Man's Game when one move gave Kaidou an entirely new perma wound while the other one didn't even open up the old one? Doesn't that prove that the "knocking down" criteria makes zero sense?
