So as always and it was expected Zoro is the true protagonist of the series leading to the greatests and more polemics debates.
This time making his haters to bite the pillow hard while crying he possibly (not confirmed) one shotted Lucci (although 3 swords can count as 3 attacks was only one named attack). And this allows us to compare him with Luffy that possibly (controversial) KOed Lucci with 3 CoCless attacks. And that's exactly where the polemics starts because we can have 2 scenarios here.
[...]
Please ignore Luffy's meaningless words since he lost 3 chapters later.
So what we can drag from this?
- CoC coating doesn't touch
- CoC coating has a black lightning streak that follows your attack while charging it
And with that we can go back to previous chapter and identify some CoC coating attacks
We can see that Zoro during his KoH mode mantains a constant flow of smoke and lightning around all his 3 swords. So for Zoro's case only we can say he has a 5th rule to be sure he is using CoC coating
- CoC coating doesn't touch
- CoC coating has a black lightning streak that follows your attack while charging it
- CoC coating clash splits the heavens
- CoC coating attack "weapon"(can be bare hand too) remains charged even after the attack
- KoH mode has constant flow of black lightning around his swords
Now let's finally analyze Zoro finisher on Rob Lucci
By elimination of our 5 rules to determine CoC coating
- We can't see any CoC coating no touching effect
- We can't see any CoC coating black lightning streak following Zoro's attack while charging it
- Zoro isn't splitting the heavens with Lucci
- Zoro swords doesn't remain charged after the attack
- We can't see the constant flow of black lightning around his swords that he has in King of Hell mode
So this is how we determine that Zoro "one-shotted" Lucci (one named attack but 3 swords means 3 attacks) without CoC coating technique.
