Kaku Kaiou is shown to have both sociopathic ruthlessness and pride in Chinese Martial Arts and its culture. He went as far as stabbing three Chinese Martial Arts Association elders in the hand with a needle before slicing off their limbs with a single hand chop. He also dismissed two current Kaious in an "emergency," replacing them with his son and best friend in the name of China and its martial arts in order to win the Raitai tournament. He even went as far as killing the other team so that a Chinese fighter would win the tournament. After his son Shunsei's flash defeat against Baki Hanma, he promised to kill him to save the Chinese team's face. Kaku then tells him he is not sure if he is really his son and that he should drop martial arts forever.

He also displays very little emotion, having 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 is shown to only respect Yuujirou Hanma, due to the fact that Yuujirou was able to beat and almost kill the old man by giving him an enjoyable match and honorable "death." Kaku Kaiou respects Yuujirou's strength and fighting abilities so much that he granted him the title of Hanma Kaiou and doesn't deny the fact that Yuujirou earned it and blesses the King by wishing they see each other next time in a hundred years for the next Great Chinese Tournament.

Kaku Kaiou, due to his more than a century-long years of experience and learning, as well as perfecting the weaknesses of his abilities, has a vast variety of knowledge in martial arts. He is a perceptive character who can very easily grasp the mentality of another person, such as how they prefer to fight and their level of power. He is very clever, having escaped death at the hands of Yuujirou Hanma through deceptive tactics. He draws inspiration from his past misguidance.

In the Hanma Baki series, Kaku is shown to make an appearance at the request of Kaiou 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 aged 146 years. He stands shorter than Baki, has long white hair, a copious amount of wrinkles over his entire body, especially prominent in his face to the point it makes it look like his head is covered in scales, and has gnarled 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, 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 shrink and wither away to his current body.

Past

Kaku Kaiou was once a young, arrogant strong-man who considered himself to be the strongest man in the whole of Asia. He believed the strong will always overcome the weak, and laughed at the logic of Chinese martial arts. He thought that the physically weaker can't beat those stronger than them. In these times, he took part in a lot of fights with wild animals and fighters. But one day, Kaku fought an elderly Chinese martial arts master and he was easily defeated by him. After that, he decided to give up with body training and started to take seriously the philosophy of Chinese Kenpo. After an extremely long time, he finally obtained the true power of Chinese martial arts. Despite being a shrunken fighter, he became the supreme grandmaster of this fighting style.
