Bad Street Brawler is a quirky side-scrolling brawler developed by Beam Software and published by Mattel for the NES in 1989. Players control Duke Dunnegan, a former punk rocker turned martial artist, as he cleans up the streets. Duke faces off against eccentric enemies like gorillas, circus midgets, and gangsters across 15 stages. Notably, it was one of the few games specifically designed for use with the Mattel Power Glove peripheral. Each stage begins with a humorous proverb, adding to the game's unique character. While controversial among critics, it remains a cult classic for its bizarre enemy variety and specialized controller support.
