We all know about the 3 Haki types that's beeing used, but I think there's one more, and this type can eliminate the other Haki's. In the best war Whitebeard stabbed Aokiji with Haki and all the soldiers where like: "OMG, is he dead". Aokiji where like a baws, and just said: "no, ofcourse not." Later we saw Vista and Marco use Haki too slice up Akainu, but did he die? No. Why would Oda make another type? Because it would be way too easy for Luffy now, if he could just use Haki to defeat Kizaru, Aokiji and Akainu. Atleast this is what I think. What's your toughts?
