KoH's Black Lightning is CoA..
AdCoC's Lightning is Red..
And why there's Red color with Black CoA lightning often?..
It shows the willpower to overwhelm your opponent, it doesn't mean that you have de facto CoC..
In a fight, you naturally want to beat and overwhelm the other..
Then Black Lightning CoA without the will to overwhelm, straight energy release..
KoH is what Raisin and Dressrosa Zoro did but on another level.. Excess CoA leaking in a stable form..
AdCoC is not leaking, it's collecting Haki..
Zoro is an AdCoC Fraud.. Deal with it..
