It seems BM noticed Enma as a non-ordinary sword...wait Oden's presence, Kaidou said?
Could it be that Enma has Oden's armament stored in it? So if Zoro can utilize it to the max / taming it /etc, it going to do attack using Zoro's haki but also release Oden's restored / hidden armament haki as well? If this is the case, then Zoro is gonna play an even bigger role in weakening Kaidou.
Law is a transporter now, but i hate how Oda makes his teleportation art design so lazy while making Kidd's robot super cool and does WWE wrestling move etc.
...and Luffy's G4-barrierless attack makes Kaidou screaming Guuaah now? And his willpower maybe manifested in his full-body covering defensive barrier haki now? Why do i can already imagine Luffy user such uber fullbody barrier armament visualized as black lightning shield and tanking Akainu's magma and Kizaru's laser rain left and right as they do aerial battles omg its gonna be epic.
...really hate it how Luffy just cheated by his rubber body to tank BM's lightning though, he should've just use the same defensive haki/willpower whatever imo.
