Duke Hyou, also known as Lord Biao or Hyou Kou, served as a Great General in the Qin military, commanding the elite Duke Hyou Army. His warrior's build featured grey hair, distinctive sharp, fang-like teeth, and ferocious, beast-like grey eyes. He wore a long mustache and a beard styled into three long goatees, typically clad in golden armor with a red cloak, wielding a glaive and a spike-rimmed shield. Duke Hyou claimed birth on a battlefield, viewing warfare as his home and living solely for combat. He rejected royal summons from King Sho of Qin, disdaining the ceremonial roles of the Six Great Generals. His philosophy centered on war as a "great blazing fire," emphasizing seizing victory at the conflict's peak intensity. An instinctual-type commander, Duke Hyou employed unpredictable, aggressive tactics. During the Keiyou Campaign against Wei, he disrupted conventional strategy by leading a 5,000-strong cavalry charge directly into the Go Kei Army’s formations at Dakan Plains. His berserker-style leadership, marked by wearing a war mask, galvanized his troops into an overwhelming force that shattered enemy lines. He personally slew Wei general Shu Ki and defeated Go Kei in single combat, mocking Go Kei’s fixation on past failures. He later participated in critical campaigns, including Bayou and Sanyou, monitoring Qin’s borders against Wei and Chu. During the Coalition Invasion, he confronted overwhelming Wei forces led by Go Hou Mei, relying on his instincts to detect dangers like the Ryudoryoku formation. His leadership at the Battle of Kankoku Pass included interrupting Chu’s opening speech with a decisive charge against Zhao forces. Recognizing Shin’s potential, he provided tactical guidance and reinforced the Hi Shin Unit with 1,000 soldiers after their rear-guard action. Duke Hyou treated Shin as a protégé, mentoring him in instinctual warfare and sharing his belief that a general’s focus should remain solely on victory. His final act occurred during a confrontation with Zhao’s Ri Boku and Hou Ken. After breaking through Ri Boku’s elite guard using intuitive tactics, he nearly beheaded Hou Ken and broke the Bushin’s dominant arm. He was ultimately slain by Hou Ken but earned profound respect from Ri Boku, who acknowledged him as the "true epitome of the instinctual type." His last words to Shin emphasized perseverance: "Don’t ever let your fire die out."
