Conqueror's Haki is an incredible ability that exists in the One Piece world among only a select few people who are born with it. These are people destined for achieving great things, and having great leadership qualities. Conqueror's Haki is present only within one in a million people and, even among those, only a few can infuse this power. According to Kaido, only a handful of the strongest know how to infuse Conqueror's Haki, and those who do gain the ability to rise to the very top of the era.
