Lee is Heihachi's adoptive son, and was originally chosen as the successor of the Mishima Zaibatsu. He was disowned, and failed to appear in Tekken 3 as he was off building his robotics business.

Law is based on the famous martial artist Bruce Lee. His fighting style is ... present in almost every iteration of the Tekken series, short of Tekken 3, when his son, Forest Law made an appearance.
