Description
The character referred to as Raul in some international releases of Fist of the North Star is the warrior Raoh, also romanized as Raou, who is known within the story by the titles Ken-oh, meaning King of Fists, and the Supreme Ruler or Conqueror of the Century's End. He is the eldest of the four Hokuto brothers, the adopted sons of the martial arts master Ryuken, and one of the central figures of the franchise.

Raoh was born in the Land of Shura as the biological older brother of Toki and the biological younger brother of Kaioh. According to the fuller version of his origin, he, Toki, and the infant Kenshiro were sent from their war-torn homeland to be raised and trained by Ryuken in the assassination art of Hokuto Shinken. He trained alongside Toki, Kenshiro, and another student named Jagi, and grew into a physically towering and extraordinarily powerful fighter. Despite his ambition to become the greatest martial artist alive, Ryuken chose Kenshiro as the official successor of Hokuto Shinken. Raoh refused to accept this decision and would not surrender his fists as the rules of the school required of those who lost the succession. He killed his master in combat and left to forge his own path, eventually building a vast army, conquering the fortress city of Cassandra, and declaring himself Ken-oh.

In personality, Raoh is defined by immense pride, overwhelming ambition, and an unshakable conviction that strength alone can bring order to a ruined world. He views conquest as a form of salvation, believing that only an absolute ruler can end the chaos of the wasteland, and he seeks to dominate not only the world but also what he calls the heavens. He refuses to retreat or show weakness, and his presence is so commanding that many opponents lose the will to fight before engaging him. Beneath this ruthless exterior, however, he is a layered figure. He shows genuine care for some of his brothers, respects opponents who display honor and courage, and is capable of compassion, as seen in his treatment of his dying brother Toki and of Kenshiro's beloved Yuria. A central part of his character is his internal struggle with fear, particularly the fear of his own limits and mortality, which he must confront in order to grow.

His motivations are rooted in a belief that only the strong have the right to rule and that peace must be imposed through overwhelming force. He is driven by the desire to become the undisputed strongest being and to prove that his chosen path of conquest is the correct one for the age. At the same time, his actions are complicated by his bonds to his brothers and to figures from his past, and he ultimately shows that his ambition is connected to a wish to spare others from suffering in a world he sees as inevitably ruled by power.

Raoh serves as the primary antagonist and greatest rival of Kenshiro during the first major portion of the story. He repeatedly clashes with Kenshiro and his allies, defeating warriors such as Rei and challenging both Kenshiro and Toki. His campaign brings him into conflict with the armies of the Holy Emperor Souther, and he later captures Yuria, drawing Kenshiro into their final confrontation. His role extends beyond his own arc, as his legacy continues to influence events after his death, and he is revealed to have left behind a son named Ryu, who carries the future of the Hokuto line. His early life and rise to power are also explored in the spinoff Legends of the Dark King, in which he is the protagonist, aided in his conquest by his childhood friends Reina and Souga.

His key relationships shape much of his development. Kenshiro is his main rival and adoptive brother, representing the values of protection and justice that stand against his philosophy of domination. Toki, his biological younger brother, is a compassionate healer whose gentleness contrasts sharply with Raoh's harshness; Raoh spares Toki when they fight because Toki is already dying of illness. Ryuken is the master Raoh kills in defiance of the school's law, an act that haunts his sense of legitimacy. Yuria is both a captive and a figure toward whom he shows unexpected mercy, as he ultimately uses his knowledge of pressure points to extend her life. His relationship with his own legacy is also defined by his son Ryu and by his origins in the Land of Shura.

Over the course of his arc, Raoh develops from an apparently unstoppable tyrant into a tragic figure who confronts his own emotional limitations. When Kenshiro masters the ultimate Hokuto technique known as Muso Tensei, Raoh experiences fear for the first time and realizes he must understand true sorrow to match his rival. Through his encounter with the hermit Fudoh and his decision regarding Yuria, he learns that sorrow and compassion are necessary for complete mastery, and he successfully acquires Muso Tensei himself. In his final battle with Kenshiro at the Hokuto Renkitōza, the training ground of the school, he is defeated but accepts his loss with dignity, acknowledging the strength Kenshiro earned through his own struggles. In his last act, he releases his remaining life energy into the heavens to restore light to the world and declares that he has no regrets for the life he lived, cementing his transformation from conqueror to a figure of tragic nobility.

In terms of abilities, Raoh practices the hard fist approach to Hokuto Shinken, favoring crushing blows, straightforward assaults, and devastating waves of energy rather than the more evasive or subtle styles used by others. He possesses superhuman physical strength, tremendous endurance, and deep mastery of the secret pressure point techniques that allow Hokuto users to destroy opponents from within, as well as to heal and even prolong life. His notable techniques include Hokuto Gōten Shō, in which he raises his fist toward the sky and projects a powerful wave of energy, and Muso Tensei, the supreme technique that allows the user to move beyond physical limitations by becoming one with the void through an understanding of profound sadness. He also commands the great black stallion Kokuoh-Go, which is as famous as its rider and becomes a symbol of his power. His abilities place him among the strongest fighters in the series, equal in scale to Kenshiro and capable of challenging the most accomplished masters of the Hokuto tradition.
