The canon continuity establishes that Billy was the victor of this encounter. However, when the time finally came to release Marian from her ties, both brothers entered a final match between themselves in order to decide who would be the one to take her home. The two brothers managed to infiltrate the gang's hideout and defeated all the enemies, including Mackey - leaving him for dead. As the series progressed, it was revealed that the reason for this abduction was to lure Billy to the Black Warriors' headquarters in order to make him surrender the secrets of the Sou-Setsu-Ken arts to them, a martial arts discipline rumored to give their practitioners unmeasurable powers. Billy teams up with his twin brother Jimmy, another martial arts expert, and both set forth on their way to rescue her from their evil clutches. In the first game of the series, the Black Warriors, commandeered by their leader Willy Mackey, kidnap Marian and take her to their hideout. Marian plays the role of girlfriend of one of the Double Dragon franchise's main protagonists, the martial arts master Billy Lee.
