Does Conqueror’s Haki have to knock someone out?


I know that it’s super rare and basically pitting your will against someone
else’s, but would it be possible to do other things with it? (Yes, I’m aware
that if your will isn’t strong enough, you won’t KO anyone and that you can
fine tune control as well.)




As stated in One Piece [Conqueror's Haki (Haoshoku no
Haki)](http://onepiece.wikia.com/wiki/Haki/Haoshoku_Haki), whoever possesses
it will have the qualities of a king. So you can control and dominate the will
power of people and other creatures like sea monsters, who are weaker than the
Haki user. By control, it doesn't mean that you can make people to do
something. But you can suppress them for a short period of time and someone
who can't bear it will get knocked out.

As explained in
[Usage](http://onepiece.wikia.com/wiki/Haki/Haoshoku_Haki#Usage) and
[Strengths and
Drawbacks](http://onepiece.wikia.com/wiki/Haki/Haoshoku_Haki#Strengths_and_Drawbacks)
of Haoshoku no Haki:

>   1. The most common usage of it shown in the series so far is using it to
> exert the user's willpower onto those with weak wills and rendering them
> unconscious.
>
>   2. One can also use Haoshoku Haki to destroy things as seen by Shanks when
> he was able to crack a part of Whitebeard's ship using his Haki.
>
>   3. Another advantage is a proficient user like Luffy can use it to tame
> powerful and dangerous animals, allowing the user to pacify ferocious beasts
> such as the Kraken or Fighting Bull.

There are very few Haoshoku no Haki users. Only one in several million people
have this ability. So, we see someone using Haoshoku no Haki very seldom,
usually when fighting with a large number of weaker opponents. Someone with a
strong will will not be affected. We might get to see more use of Haoshoku no
Haki in future.
