Shanks from One Piece, commonly known as Red Hair is the chief of Red Hair Pirates and one of the Four Emperors that rule over the New World. He sacrificed his arm to rescue Luffy during Luffy’s childhood and presented him with his cherished Strawhat as a promise to reclaim it when Luffy becomes a great Pirate. Shank’s strength so far is the greatest use of Haki in One Piece starting from King Haki, Busho Haki and Garden Haki.
