Kaioh Kaku (郭 海皇, Kaku Kaiō; Chinese pinyin: Guō Hǎihuáng) is the greatest and renonowed Supreme Grandmaster of Chinese Martial Arts, the Kaioh of Kaiohs and current champion of the Raitai Tournament over the last century. He is also captain of the Chinese Team representing China in the Raitai Tournament. Kaku Kaioh is also father of Shunsei Kaku.
Kaku Kaioh has shown to be both sociopathic ruthlessness and prideful in Chinese Martial Arts and its culture going as far as stabbing three Chinese Martial Arts Assossciation elders in the hand with a needle and then slicing off their limbs with a simple hand chop and dismissing two current Kaiohs due to "emergency" to replace them for his son and best friend in the name of China and its martial arts to win the Raitai tournament and not lose to foreigners going as far to even kill the other team so that a Chinese fighter would win the tournament.
He has also displayed very little emotion and has abandoned all joys of life in the pursuit of strength and being the strongest martial artist in the world.
While old age has made him look down on the younger fighters he has shown to only respect Yujiro Hanma due to the fact that Yujiro was able to beat and almost kill the old man by giving him an enjoyable match and honorable "death." Kaku Kaioh respected Yujiro's strength and fighting abilities so much he granted him the title of Hanma Kaioh and doesn't deny the fact that Yujiro earned it and blesses the King by wishing they see eachother next time in a hundred years for the next Raitai Tournament.
In the Baki: Son of Ogre series Kaku is shown to make an appearance at the request of Kaioh Retsu to help train and aide Katsumi Orochi in the fusion of Chinese Kung Fu's 4,000 years with Karate's 500 year history. In this series Kaku is shown in a more nice and friendly personality with a bit of comedic sense.
He is a shrunken almost skeleton framed elderly man being 146 years old being shorter then Baki with long white hair, a largely and distinguished amount of wrinkles throughout his entire body and face and has very long finger nails. Attire wise he wears a Chinese cap and round glasses on his head. A light colored knee length tangzhuang jacket and matching pants with kung fu shoes. When not fighting he is seen sitting in his wheelchair.
In his youth he is seen being very large and muscular being almost the same size as Biscuit Oliva. His long black hair being tied in a traditional topknot and wrapped in a cloth with a robe wrapped and tied around his waist. But due to his first loss at the hands of an elderly Kung Fu master Kaku abandoned all weight training equipment and began his Kung Fu training only to notice his once large muscles began to shrunk and wither away to his current body.
Kaku Kaioh being a supreme grandmaster of Chinese martial arts has a wide knowledge of everything.
