Japanese name: Kakou Ton. Chinese Name: Xiahou Dun. Xiahou Dun was a military general under the powerful warlord Cao Cao of Wei during the late Eastern Han Dynasty and Three Kingdoms era of China. Cao Cao's original family name was Xiahou, but his father, Cao Song, was adopted by the Cao family, so Dun and Cao share family relations. One of the most trusted men of Cao Cao's, Xiahou Dun aided the warlord in his campaigns against Liu Bei, Sun Quan, and Lu Bu. Infamous for eating his own eye after it was shot by an arrow in battle. With the quote, "Essence of my father, blood of my mother, I cannot throw this away," he exclaimed and swallowed the eye. His image as a one-eyed warrior was later popularized by the historical novel Romance of the Three Kingdoms, in which he was said to have yanked the arrow fired by enemy general Cao Xing out of his eye and devoured his own eyeball to instill fear in his enemies.
