I was here trying to wrap my head around ambition of the conqueror (Kings Haki) and some ideas came to me about how it might be of importance in the future. I chose this one because most persons cannot fully get a grasp on the concept so let me get to explaining.
When I think of Haki I am reminded of the various powers that exist in other mangas and animes that help to increase a fighters potential. In most cases, it is referred to as spirit (Ki) like Dragon Ball, Nem in HxH, and some mangas that involve magic use manna but whatever it is referred to it is still the same concept just different ways of explaining and using it. Think back on Dragon Ball when we see Goku or anybody for that matter release their Ki the author always use different visuals to show how much stronger they have gotten by having it affecting the the world and people. When ki is released we see rocks breaking, breeze flying and people getting blown away, we also see people getting scared to fight and giving up hope, some faint these references may not only be from Dragon Ball. Let me use Bleach as well when a captain release their spiritual pressure we see persons who are not strong enough falling to their knees in some instant we see persons suffocating. Additionally the author always let the characters use the spiritual pressure to augment their fighting skills and power if the manga is power base.
What I explain are things already known by most, I know some might start to say "not this again", so I will get to it. The first time we see Haki affecting something physically was shanks meeting with White Beard, hence the Dragon Ball reference. Therefore, what we get from this, that if your Haki/spiritual power is strong enough it can be manifested outwards creating force, it then can be seen as something tangible. Another example is the admirals putting up that force field to ward off White Beard ability. I think it is similar to the previous example hence Shanks Haki creating a force field that is pushing against White Beard's ship.
How will Conqueror Haki works? Here are some examples of how I think it may become relevant in combat:
1. Overpowering an opponent's will that render them unable to fight something we all know.
2. Coating your body or armor with Conqueror Haki and amplifying your attacks this will allow your will to clash against another therefore depending on who's will is stronger they will overpower the other damaging any defense that person have in place.
3. I think this is the one that I believe in more even though it is far fetch, allowing a Conqueror user to apply it to their attack and disrupt a devil fruit user ability to use the devil fruit effectively. The way it will work is the same as Monet not able to put herself back together after getting slice by Zoro and similar to how Law disrupt Trebol ability leaving him unable to put himself back together for some time. Therefore, it will be something like a Conqueror's injection. Another example is Ralige sp using it to take off Cami neckbrace that would normally explode if taken off otherwise.
4. Using it to augment the other type of Haki. As it relates to COA it fits with example two, and COO it will increase the range similar to Enel also it will allow the user to hear the voice of all things same like Roger and Luffy this will be the key to finding One Piece something Black Beard will not be able to do. This point is somewhat iffy as roger ask Whitebeard if he wants to know how to find One Piece.
