Lei Fang (レイ・ファン, Rei Fan; 雷芳,Léi Fāng) is a college student and Tai Chi Quan prodigy from the Dead or Alive series, who made her debut in the first Dead or Alive. She is one of the first females to appear in the series, alongside Kasumi and Tina Armstrong.
A girl who grew up in a wealthy family, Lei Fang is a woman of justice and bares a very independent spirit. Throughout the series, she seeks to fight Jann Lee, who is thought to have saved her life at one stage in her past, to prove herself to him that she too is a strong individual. However, Lei Fang had lost to Jann in almost every tournament, but she managed to defeat him in the last one.
