Renegade is a video game released in American and European arcades in 1986 by Taito. It is a westernized conversion (including changes to all of the sprites and backgrounds) of the Japanese arcade game Nekketsu Kōha Kunio-kun (熱血硬派くにおくん?, which roughly translates to "Hot-Blooded Tough Guy Kunio"), released earlier the same year by Technos. It is an immediate technological predecessor to Double Dragon, and Nekketsu Kōha Kunio-kun is the inaugural game in the Kunio-kun series (which includes Super Dodge Ball and River City Ransom).
Renegade first introduced several trademarks of the beat 'em up genre, including 4-directional control, punch-jump-kick play action, and enemies which can sustain multiple hits. It is considered to be one of the most influential titles of the video game industry
