User blog:CNBA3/Armament Haki Confirmation.

I would just like to get a quick confirmation about whether, Armament Haki was created to counter Devil Fruit Users, or that Devil Users just doesn't have any natural defense to Armament Haki. Which would it be?

My understanding is that Devil Fruit powers don't have any defense against Armament Haki. Reason for being and my theory, that since Haki exists inside every living being, it would have come first possibly before Devil Fruits, from what they were seen in labs and such, they appear to be man made so they would come later and thus would be vulnerable to Haki.
