I’ve been doing a rewatch/read of the series this year and I’ve recently been looking a lot at the Full Body Armament Haki users. I’d say Vergo was ridiculously strong with it but it didn’t do much for him in the end. I think he lacked the speed that other characters have, and relied on brute force.
Another Full Body Armament Haki user was Pica, but this technique did basically absolutely nothing for him as Zoro had no problem cutting right through it.
I’ve seen some people say that Full Body Armament Haki is kind of useless, you only really need it in the part of the body you’re using to block or attack. Reasonably we can assume that it’s stronger if you focus it in 1 area.
So I was thinking about how Luffy essentially makes full efficiency of “Full Body” Haki in Gear Fourth by only using it in the areas that mattered, but still retaining the almost fully enveloped feature. The problem is that it’s so exhausting that he loses almost all of his fighting capabilities after a short period of time.
Rayleigh said that he will need to find a more energy-efficient fighting style since this is so exhausting in his body. Luffy’s gut response was “let’s make it more exhausting” essentially, lol. Which is a very Luffy style response.
Honestly all of Luffy’s Gears have been physically trying, and each one is worse for his body and stamina than the last. Gear Second is said to be bad for his health and pre timeskip he couldn’t keep it up constantly, but in battle it’s pretty fine by now. Gear Third pre timeskip was incredibly bad for him, as after just a few attacks he shrunk to an non-combat-possible size. But he has since fixed the issue. Gear Fourth of course has the stamina issue, but like his others Gears as he comes to master it I feel it will become rather easy for him to handle. Then this will bring even MORE exhausting Gears. I strongly doubt that his next level up will be a less taxing ability, that’s just not really his style.
So what would it be?
