As y'all know the Fighting Style of Fei Long from Super Street Fighter II Hiten Ryū Kung Fu is based on Bruce Lee's Hybrid Martial Arts Philosophy of Jeet Kune Do.
Jeet Kune Do is a Hybrid Martial Arts Philosophy created by the Late Great Bruce Lee. It combines Wing Chun Kung Fu with Western Boxing, Western Fencing, and the French Martial Art of Savate as well other techniques.
One of the main Principles of Jeet Kune Do is to break free from one Style and use whatever works for the individual so they can express their true selves through Combat and life as a whole.
One of the main quotes that hits this home is "Absorb what is useful, discard what is useless add what is uniquely your own."
There are other Fighting Game Characters that use Jeet Kune Do. Like Liu Kang and Johnny Cage from Mortal Kombat.
Jacky Bryant and Sarah Bryant from Virtua Fighter. Although Sarah Bryant will combine Jeet Kune Do with Taekwondo, Savate, and Karate.
Marshall Law, Forest Law and Lee Chaolan from Tekken. Though with Lee Chaolan he combines it with Savate, Western Boxing and Taekwondo. Originally he combined it with Mishima Style Karate in Tekken 1,2, and Tag 1.
The base System for Jeet Kune Do is Jun Fan Gung Fu which Bruce Lee created earlier. It combines the different Kung Fu Techniques and Styles that he learned from both Yip Man and Siu Hon San (Siu Hon Sang) with Western Boxing and Western Fencing.
