without coc
zoro prob has a weary match against king. a bit more like luffy had with katakuri
super drawn out
but he still wins because each time those flames go off , he would get cut.... bad...... and am sure zoro gets hurt too.
zoro getting coc essentially fucked king either way, he no longer felt invincible flame on or off and thats exactly why it looked like a thrashing. The reason he couldnt beat him was stated by zoro himself. figuring out what king was i.e how his body worked.
Thats the key to winning.
