First Appearance: Fist of the North Star: Ken's Rage 2

Kaioh (カイオウ) is Raoh, Toki, and Sayaka's eldest biological brother. He bares an uncanny resemblance to Raoh, even causing Kenshiro to mistake him as such when unmasked. After Raoh's death, Kaioh sought to continue his younger brother's legacy in Shura. Like Raoh, he wears intimidating armor, rides a giant red horse, and leads his own army. Unlike Raoh, Kaioh seeks to conquer the world in the name of evil, hoping to establish his reign by crushing Hokuto Shinken for all time. To facilitate his dark nature, Kaioh uses self-harm to purge himself of love and empathy, leaving his entire body covered in scars, and where his mastery of Hokuto Ryuken has lead him to wear his armor not for protection against others, but to contain his strength of Matoki claimed to be gained from having reached into the demonic realm from ravaging everything near him.

Kaioh and his family line come from the protective branch of the Hokuto ancestry line, essentially being their guards when and if danger arises. When Kaioh's mother loses her life to protect the Hokuto ancestors, Kaioh bears a seething hatred for their descendants. Unable to overcome his grief for his mother's death, he swears to cause Hyou and Kenshiro unimaginable suffering. He secretly kept the seal over Hyou's memories and manipulated the brothers to be enemies.

When he learns that Rin is a descendant of the Celestial Emperor's bloodline, he has her abducted to bear his children. He thinks that the divine ancestry can cleanse the curse on his family line. Throughout the story, he immobilizes and tortures those close to Kenshiro. Yet even with all of his schemes, he is infuriated to learn he is ultimately trumped by the power of love shared between them. In a race to obtain the secrets of the Hokuto ancestors, he challenges Kenshiro to a duel at the Hokuto holy land. His cruelty loses favor with the spirit of the Hokuto ancestors and Kenshiro inherits the style's secret technique. At the end of their fight, Hyou tackles him into a pool of magma. Both of their corpses fossilize as stone statues.

Fighting StyleEdit

Kaioh is very similar to Raoh in both fighting style and appearance - Hisashi Koinuma remarked that it was troubling to devise attacks to differentiate them. Kaioh's techniques generally make use of his "Demonic Mighty Aura", which manifest as devastating energy spheres or waves. His moves lack the wide range of Raoh's techniques, but tend to be even more powerful to enemies unfortunate enough to be caught in them.
