The Mysterious Warrior[3] (謎の格闘家 Nazo no Kakutō-ka?, lit. "Mysterious Fighter") is the final boss in the Famicom/NES and PC Engine CD versions of Double Dragon II: The Revenge. He replaces Willy as the game's main antagonist in those versions of the game.


The Mysterious Warrior's true name and origin are unknown. All that is known about him is that he is a master of a deadly martial art known as Gen-Satsu-Ken (幻殺拳?, lit. "Phantom Murder Fist"), whose school has been in conflict with the Lee brothers' own style of Sou-Setsu-Ken (双截拳?) for generations due to their opposing ideals.

He is the leader of the "Black Shadow Warriors", which targets various martial artists, including the students of the Lee brothers' own school. When Billy Lee's girlfriend, Marian, is killed during one of their attacks, the Lee brothers pursue the organization until reaching their island stronghold, eventually coming face to face with the leader himself. 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:

"If the illusion spreads the evil will live again.
But if two dragons soar through the sky,
an angel will fall to the Earth."

After dying, that night Marian miraculously comes back to life and is returned to the Double Dragons alive and well.

In the Famicom version of Double Dragon II, the 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").

The battle against the Mysterious Warrior consists of two phases. During the first phase, he fights on a green battlefield in the middle of the night featuring a demonic statue and a pair of eyes staring in the background (in the PC Engine CD version, this illusory backdrop is even more surrealistic, resembling an alternate dimension). After he has sustained enough damage, the illusion breaks and the background changes to the interior of what appears to be an ancient temple, in front of an altar. His techniques include a thrust, a roundhouse kick, a backflip kick, and a spinning clothesline. In addition, he can also turn invisible at will during the first phase.

In the PC Engine CD version, the Warrior can be fought on any of the three different difficulty settings, although the ending differs depending on the choice. On the easiest setting, the Warrior will escape after the first phase of the fight, mocking the Lee brothers for their failure to defeat him and resulting in the bad ending.


  • The English manual for Double Dragon III: The Sacred Stones retrospectively mentions the Mysterious Warrior and calls him by the name of "Supreme Black Shadow Sensei".[2]
  • The criminal organization the Mysterious Warrior leads, the "Black Shadow Warriors", is most likely the same Black Warriors from the first game, probably having reorganized after their first defeat. The change in the name could be attributed to publisher Acclaim, known for often changing established terms.
    • In the PC Engine CD version of Double Dragon II, the organization is specifically given the name "Shadow Warriors", and it is indeed treated as the same organization as the Black Warriors.[4]
      • Further supporting this, is that in this version, Willy, the main antagonist from the first game, appears as an underling to the Mysterious Warrior, probably being his second-in-command (he is fought before the Double Illusion, although these could just be magical servant creatures with no commanding rank in the organization).



  • While his organization is never given a name in the Japanese version, the English localization refers to it as the "Black Shadow Warriors" in the manual, and "Shadow Warriors" in the opening sequence. The only other time the term "Shadow Warrior" appears in the English script is when the player character uses it to address the Mysterious Warrior himself prior to their final confrontation. "Shadow Warriors" would be used as the name of the enemy organization in later games and works, such as the animated series, Double Dragon V and Double Dragon Advance.
  • Even though the Mysterious Warrior is shirtless during the final confrontation in the PC Engine CD version of Double Dragon II, he appears with his full costume during the subsequent cinematic.
  • In Double Dragon Advance, a group of enemy characters modeled after the Mysterious Warrior appear as an elite group that serve as Willy's bodyguards. They are known as the "Five Emperors" and appear as the end bosses of the penultimate stage. While all of their members borrow traits from the Mysterious Warrior, their leader, Raymond, is strongly implied to be the Mysterious Warrior himself (or at least his counterpart or successor). Besides using many of the Mysterious Warrior's characteristic moves, such as the spinning clothesline and the ability to become "invisible" (shadow trail), the Mysterious Warrior's theme, "The Fight Continues/Fight of Fate", will start playing when he enters the battle. Furthermore, when he is defeated, the screen will briefly turn to black and white and the action will turn into slow motion, just as it did when the Mysterious Warrior was defeated in the NES version of Double Dragon II.
    • Further supporting this theory, Raymond and the PC Engine CD version of the Mysterious Warrior wear very similar clothes, consisting on a sleeveless purple costume with shoulder pads (sans the cape from the latter) and both fashioning long hair in a mullet style (although Raymond has his tied in a ponytail on the back).
