Black Belt is a side-scrolling single-player beat 'em up game released for the Master System in 1986. It is a localization of the Japanese Mark III game, Hokuto no Ken (北斗の拳), based on the manga and anime series Fist of the North Star (known as Hokuto no Ken in Japan). The export version was released without the Hokuto no Ken license, forcing graphic alterations to the game. Black Belt was one of programmer Yuji Naka's early games prior to his involvement in Sonic the Hedgehog.
