User blog comment:Uraharattack/King and his Haki/@comment-124.171.141.43-20190124040429

While I agree that the markings shown by Big Mom, Katakuri and Luffy might be a more powerful form of Buso. I don't think you can say that Vergo and Pica are the most proficient users we've seen.

Firstly I need to mention this. Haki is willpower. The stronger the persons will the stronger the haki. Therefore the ability to cover any object in haki and the strength of that Haki is tied directly to the strength of the users willpower.

Basically I think that the ability to cover your body in Haki is just a trick that anyone at a sufficient level can do. Most don't do it becasue Haki is tied to concetration and will power, a single lapse in either will break your defense. So why bother having it up all the time when all it does is just expend your Haki. All it's good for is making you look like a badass

When Vergo first demonstrated this ability he does so after Law gets his heart back. He uses it for four panels before Law just cuts him in half in the fourth. Whats more Law does so just by using his devil fruit powers as his sword is drawn without the effect. (we know that Buso circumvents devil fruit powers. That it didn;t means Law's will is stronger than Vergo;s

The same thing happens when Zoro fights Pica. Pica covers his body in Haki, Zoro Covers his swords and cuts through Pica, again in only four panels. This means that both Law's and Zoros willpower was stronger than their opponents, thus their Haki is greater, thus they can perform the same trick they just don't bother.

I think you might be on to something with King and his mastery of Buso. As a commander he's certainly powerful enough to both cover his body with Buso and get the flame like markings. Whats more we know (or can safely assume) that the fire he has around him has nothing to do with his devil fruit power, since (as far as we know) Pteranodons could not control fire or generate it. However we do know that Buso can create flames (Luffy' Red Hawk, also whatever Sanji does).

I don't think their would be elemental affinity per Naruto or Avater, were certain people have the ability to manipulate, generae or control a certain element. Any elemntal techniques will be using some vague science bullshittery. e.g. Minks use electro becasue static-electricity/ bio-electricity, Fishmen manipulating water via ability to 'grab' it, Sanji and Luffy using fire by heating up their bodies.

As for Kings feathered wings I think they're either real and he's some skypeien varient, or their just decoration like Magellen's horns and wings.

Also Buso users don;t 'extend' their haki they 'coat' it. In my mind the difference is that the user applies their willpower to an object or themselves in a similar manner to someone putting their all behind a strike. So you can probably use Haki for Baseball to hit a homerun just as easily as using it in a sword fight to cut through your opponent.

To sum it all up. Pica and Vergo are not as good as you give them credit for. Elemental affintiy is probably not a thing. King will hopefully be the introduction to high teir aramament tricks like Katakuri was for observation.
