In the Famicom version of Double Dragon II, the Mysterious Warrior always appears regardless of the difficulty the game is set on, whereas in the NES version, he only appears on the hardest setting ("Supreme Master"). That night, Marian miraculously came back to life and was returned to the Double Dragons alive and well. "If the illusion spreads the evil will live again. After an arduous battle, the brothers manage to defeat the Mysterious Warrior, who with his last breath tells them about an ancient prophecy that has been passed down his school for generations: When Billy Lee's girlfriend, Marian, is killed during one of their attacks, the Lee brothers pursue the organization to their island stronghold and eventually come face to face with their leader himself. He is the leader of the Black Shadow Warriors, a criminal organization which targets various martial artists, including the students of the Lee brothers' own school.


All that is known about him is that he is a master of a deadly martial art known as Gen-Satsu-Ken, whose school has presumably been in conflict with the Lee brothers' own style of Sou-Setsu-Ken. The Mysterious Warrior's true name and origin are unknown.
