The following is a list of characters from the manga and anime franchise Fist of the Blue Sky (Japanese: 蒼天の拳, Hepburn: Sōten no Ken) by Tetsuo Hara and Buronson. All characters are from the original manga unless otherwise noted.
North Dipper Divine Fist" (Japanese: 北斗神拳, Hepburn: Hokuto Shinken, Pinyin: Běidǒu Shénquán). Called "God Fist of the North Star" in the Gutsoon! Entertainment English translation.
The North Dipper Three Family Fists (Japanese: 北斗三家拳, Hepburn: Hokuto Sankaken, Pinyin:Běidǒu Sānjiāquán) are three martial arts styles that branched off from Hokuto Shinken during the Three Kingdoms period and went on to develop their styles independently after the main Hokuto Shinken school was relocated to Japan. They are named after the Cao, Sun and Liu families, which they were each sworn to protect and serve. The Liu Family Fist would later branch off from the other school and become the Hokuto Ryūken school from Fist of the North Star.
"Pole Cross Sacred Fist" (極十字聖拳, Pinyin: Jíshízì Shèngquán), an offshoot of Hokuto Ryūkaken. A relatively new style compared to the Hokuto styles, its astrological symbol is the constellation of the Southern Cross and uses stabbing techniques that destroys the body externally.
"West Dipper Lunar Fist" (西斗月拳, Pinyin: Xīdǒu Yuèquán). A martial art of the Yuezhi people. Shuken studied this martial art and blended it with his Hokuto Sōke no Ken (北斗宗家の拳, lit. "North Dipper Lineage's Fist") to create Hokuto Shinken. Seito Gekken uses the Keiraku Hikō, the same vital points used by Hokuto Shinken, to cause destruction, but does so through hitting multiple points through the course of a fight rather than hitting a single point.
"Heaven Dipper Sacred Yin Fist " (天斗聖陰拳) is the ancient martial art of the Nahash (serpent) tribe. The Nahash existed before Christ and defended Migdol and the Promised Land. It is a development of the Seito Gekken style from when the Nahash people from the west met the Yuezhi people from the east. Its proponents produce glowing fists which leave burn marks on their opponents. This style is used by Van der Kohl, Simeon Nagid, Himuka, and Shomer.
Qīng Bāng (青幇, Chinpan) is the Shanghai "Green Gang".
Shanghai's evil "Red Flower Gang" (紅華会, Kōkakai). Most of them were maimed in some way by Kenshiro during a previous visit to Shanghai prior to the start of the series. Based on the real life Red Gang (紅幫 Hóng Bāng) in Shanghai.
