I think there is an elemental factor to it as well. Outside of Foxfire Kinemon, we also have Shiryu of the Wind. We have two Swordsman with Elemental themes to their name. It's also interesting to note that Zoro himself can create Wind based attacks, so pitting him up against someone who has a direct counter to his moveset (Shiryu being capable of cutting through wind) is something I see Oda doing.
And his sword is called thunderstorm
And his cuts look like lightening
