Conqueror's Haki is a powerful ability in the world of One Piece, a popular manga and anime series created by Eiichiro Oda. This ability allows its user to exert their willpower over others, intimidating or even incapacitating weaker opponents. It is a rare skill, possessed by only a select few individuals, often those with strong leadership qualities or a fighting spirit. To use Conqueror's Haki, a person must have a strong will and the innate talent for it, as it cannot be learned through training. When activated, it creates an aura that can affect those nearby, causing them to feel fear or faint. Notable characters like Monkey D. Luffy and Gol D. Roger are known to possess this formidable ability.
