Powerman
is a 1991 beat 'em up video game developed by Tamtex and published by Irem exclusively in Japan for the Family Computer. It is a sequel to Irem's 1984 coin-operated video game "Spartan X" (released internationally by Data East under the title of "Kung-Fu Master"), which was later ported to the Family Computer by Nintendo in 1985. In turn, "Spartan X" was originally a tie-in to the 1984 Jackie Chan film "Wheels on Meals" (released as "Spartan X" in Japan).
