Shadow-Stalker is a talented martial artist who was taught by Sifu Chow and would become Fu Manchu's favorite assassin. His trademark ball and chain headpiece makes him truly unorthodox and dangerous. Shadow-Stalker would face Shang Chi
in combat but is defeated by the superior martial artist.
These two men would meet again when Shang Chi returns to his father's fortress and learn that Sir Denis Nayland Smith was abducted. He learns that there is a war between Fu Manchu
and his daughter Fah Lo Suee
. Fah Lo Suee is in possession of the ruby eyes and she uses its power to channel her will into others who are weak of spirit. She is trying to build an army of Si-Fan to rival those commanded by Fu Manchu. Suee tells Shang Chi that she needs a strong ally and wants him to join her side.
