Choujin Sentai Jetman
Based on the Japanese Super Sentai franchise from which Power Rangers would later be adapted, this is a pretty fun side scrolling beat 'em up game, also has a giant robot fighting mini game!
This game is based on the 15th entry in Japan's Super Sentai franchise.
It was exclusively released in Japan in 1991 - Power Rangers wouldn't exist for another two years. A typical beat-em-up, with the twist of also having to fight enemies one on one in the giant robot.
