Pelea de colosos

Yujiro Hanma/The King (範馬 勇次郎 Hanma Ujirō) Voiced by: Kenji Nomura - 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. Below is a list (no order) of styles Yujiro has fought and won against:
Brazilian Jiu-jitsu
Kickboxing
Judo
Sumo Wrestling
Greco-Roman Wrestling
Various forms of Karate including Doppo's Shinshinkai
Aikido
Sambo
Street fighting
Jujutsu
Boxing
Military fighting tactics of Green Berets, Navy Seals, and Army Airborne Rangers

Raoh is the eldest of the four adopted children trained by Ryuken, the previous Hokuto Shinken master. The manga and anime gives two different origins thorough the course of the story. In his first origin, Raoh and his biological younger brother Toki, were adopted by Ryuken after their real parents died. A second origin shows that a young Raoh and Toki, along with an infant Kenshiro, were actually refugees from the Kingdom of Shura who were sent to Japan to be trained in the art of Hokuto Shinken by Ryuken after their homeland was torn apart by a civil war.
Raoh trained under Ryuken along with Toki and Kenshiro, as well as another student named Jagi. In spite of his ambitions to become the greatest martial artist in the world, Raoh lost the rights to the Hokuto Shinken succession to Kenshiro. Refusing to give up the style, Raoh killed his sifu Ryuken in combat and leaves to become the savior of the world.
