Yujiro Hanma (範馬 勇次郎 Hanma Ujirō) The father of Baki and Jack Hanma. He is the strongest creature in the world, and is known to have mastered all styles of unarmed combat. His repertoire apparently includes all of the well-known fighting styles (such as karate, boxing, taekwondo, judo, jujutsu, wrestling, street-fighting, and so on) as well as some more esoteric ones (such as the udonde or uzunde style, an actual system used in the Motobu style of karate).
