The game started out as a sequel to the NES "Punch Out!!" called "Mike Tyson's Intergalactic Power Punch." The plan fell though when Tyson was arrested and accused for rape charges. Because of this, the character had to be renamed "Mark 'Tough Guy' Tyler" (even though the sprite was not change drastically) and the title was renamed to Power Punch II, although there was never a Power Punch I.
