The Dragon Ninja is the titular villain from Bad Dudes Vs Dragon Ninja, acting as the game's final boss. He commands an army of ninjas, who have been committing crimes all over. They kidnap the President Ronnie, which prompts the army to send the two Bad Dudes to rescue the president and teach those ninjas a lesson, armed only with their fists. They beat up all of the evil ninjas and finally rescue Ronnie after defeating the Dragon Ninja.
The player will face the Dragon Ninja after defeating all previous bosses in succession. He will just stay high on his helicopter throwing explosives below while calling dogs to attack the player.
