@inderos:
Which characters have we seen turn black from haki so far? Luffy, Vergo and Smoker? I can't remember anyone else… What if the hardening is created when someone uses CoA with CoC? We've all wondered what the purpose of CoC is besides knocking out fodder and Shanks seems to have used it to damage Whitebeard's ship.
I think it's very likely that Smoker has CoC and possible Vergo does as well. This would explain how Luffy's use of haki is different and why Oda sometimes draws it as black and other times does not. CoA creates the armor and CoC strengthens it.
No just no,we can't give CoC to everyone.
It ight depend on the type of body or it is just a CoA tech that no one used pre TS.Or it is just a way to show when someone is using Haki.
Though it really affects Luffy's DF.
Anyway.Can really Momonosuke carry Luffy?I think it will be better if Luffy does something crazy by himself.
