Lü Bu (? - 199 A.D) was a military general and warlord who lived during the late Eastern Han dynasty. No descriptions of Lü Bu's physical appearance exist in historical records. It was noted that he specialized in archery and horse-riding, and possessed great physical strength. He was nicknamed "Flying General" (飛將) for his martial prowess. Although Lü Bu is described in historical and fictional sources as an exceptionally mighty warrior, he was also notorious for his temperamental behavior. He switched allegiances erratically and freely betrayed his allies, and was noted for his poor planning and management skills. He was always suspicious of others and could not control his subordinates. All these factors ultimately led to his downfall.
