User blog comment:The ASL Pirates/Haoshoku Haki Theory/@comment-4899461-20150216034954

It's an interesting theory for sure. For me, Conqueror's Haki has always been an interesting idea.

It's definitely tied to people with strong wills, for sure. But also, it seems to me like strong wills are tied to ancestry. So it's hard to say what's to blame for what.

Luffy & Ace are both decedents of great Marines/Pirates. Doffy is descended from the creators of the WG, which were all Kings. Hancock is the Empress of Amazon Lily, and while we don't know how the Empress is chosen, if it is by blood, that would be another one for the descent list. Chinjao is the head of a large Navy/former great Pirate, and being head of that Navy seems to be passed from Generation to Generation.

Naguri is a filler character, so he doesn't really count for anything, I'm afraid. I'm sorry in advance for other users making fun of you for mentioning him.

So that leaves 3 guys: Rayleigh, Shanks, and Whitebeard. 2 Yonko and the First Mate for the King of The Pirates. Definitely guys with a lot of ambition, but unfortunately we know nothing of their heritage.

Also worth noting is that after they clashed, Chinjao asked Luffy "Just what do you dream of becoming King of?" To me, this seems to indicate that there is some kind of desire in all users of H-Haki to have king-like ambitions (though notably, Ace and Whitebeard didn't really want kingship in its purest forum), or at the very least some kind of Myth that goes along with the Haki.
