so finally gear 4 pops up….. it just had too.
so my ideas on this vary the 1st one being a concentration on normal hand to hand combat without the use of his devil fruit. It would have been something he developed in case of a fight with blackbeard. 2nd idea is a haki based fighting technique using variations that include fire type, lighting type and stuff we havent seen yet...and a hint on what makes coc haki so special cuz it cant be just to make small fry faint (i can do the same with my farts). 3rd is an area of effect ability with his devil fruit, kinda like diamante who apart from having his body turn into a flag but can also affect any weapon he holds turning it into a flag.
