Hiryuu no Ken, meaning "Legend of the Dragon", is a series of action games primarily released in Japan for the Nintendo Entertainment System. The games follow a consistent theme of martial arts combat and often involve dragons or dragon-related mythology.  Gameplay typically involves side-scrolling beat 'em up action, with players controlling a warrior who fights against various enemies.  The series is not widely known outside of Japan, making these titles relatively obscure to Western audiences.  While each game features similar gameplay mechanics, they offer unique storylines and character rosters within the shared universe.  The developer and publisher of these games are not consistently documented in Western databases and typically require searching through Japanese resources for complete information.
