Yujiro Hanma
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). He has been fighting on the battlefields, using only his bare hands, since the age of sixteen, when he fought against both American and Vietcong in the Vietnam War. Since then, it appears that he has obtained respect from the American forces, and has begun fighting as a kind of mercenary for them. It is said that when he stopped fighting for survival but for pleasure the image of the demon's face appeared on his back.
