Lee Chaolan / Violet Move List (Command List) | Tekken 7 Season 5 (Patch 5.01) | HD 60 FPS 2022

In Tekken 2 and Tekken Tag Tournament, Lee fought using Mishima Style Fighting Karate combined with his own style of "Martial Arts". Being a variation of Marshall Law's moveset (which is heavily inspired by Bruce Lee's moves), it's safe to assume that Lee's actual fighting style is based on Jeet Kune Do. The only Mishima Karate moves of his, however, are his Left Splits Kick (f,f+3), which was removed in Tekken 5, and the two first kicks of his Infinite Kick Chain, which resemble the Mishima Tsunami Kick (ws+4,4) but with the other leg.
Since Tekken 4 and onwards, Lee's fighting style is listed simply as "Martial Arts", alluding to the idea that Lee fights using hybridized techniques from other fighting styles combined into one. From then on, many of his attack movements and motions stem from JKD, taekwondo, boxing and even savate techniques.
