@Grudge and @Nedoiko - From what I understand, we're not flat out suggesting that an opponent would automatically have "haki", but energy-based attacks (produced from ki, chakra, etc, but not from a gun) would be capable of directly harming the logia user's body.
Physical attacks and the like would still be totally worthless in live combat, and I'd also like to mention that logia users can utilize their own haki in order to cancel out the attacks of other haki users. The most notable showing is when Akainu was struck by Vista and Marco, who he stated were using haki, yet he was still capable of using his logia-form. Another showing of this, but for a Paramecia user was when Luffy used his haki to protect himself from a haki infused attack from Doflamingo, while also maintaining his rubbery body while in Gear 4th. How would this come into play in a versus match-up?
Also, I'd like to point out that I believe that I've added
Body Control for all of the Logia users, and if i missed any pages, someone should add it like how I placed it on
Sabo's profile.
