Double Dragon (双截龍ダブルドラゴン, Daburu Doragon - Sō Setsu Ryū) is a beat 'em up video game series originally developed and published by Technōs Japan. It began with the release of the arcade game Double Dragon in 1987. The series features twin martial artists, Billy and Jimmy Lee, as they fight against various adversaries and rivals. The original Double Dragon was a hit arcade video game,[1] ushering in a "Golden Age" for the beat 'em up genre,[2][3] resulting in a flood of beat 'em ups during the late 1980s[3] to 1990s that followed the conventions set by Double Dragon.[4] A 1993 animated series and 1994 live-action film adaptation were produced; these adaptations were widely-panned by critics and audiences.[5] In June 2015, Arc System Works acquired the rights to all former Technōs IPs, including the Double Dragon series.[6] Arc System Works had previously ported the original Double Dragon to the Master System console in 1988.
