The Game Boy version of 'Double Dragon II' is an English localization of a 'Kunio-kun' game (the Japanese franchise which inspired 'Renegade' and 'River City Ransom' and has nothing to do with the arcade and NES versions. Unlike the first NES game, it offered 2-Player Co-Op gameplay with the option to turn off the friendly fire. The NES version offered new stages, new moves and illustrated cut-scenes, as well as a new final boss and a new ending. In addition to offering renewed audio and visuals, as well as new traps, moves and enemy characters, 'Double Dragon II' discarded the conventional punch and kick buttons in favor of a direction-oriented attacking system similar to the original Technos beat-em-up Renegade. The original arcade version of 'Double Dragon II' was essentially an improved version of the first game. The Dragons must now embark on a mission to avenge her death and defeat the Black Warriors for the second and final time.

The lovely Marian was rescued from the clutches of the Black Warriors gang by Billy & Jimmy Lee in the first Double Dragon game, but now the gang has killed her in retaliation of their early defeat.
