Due to Nintendo's censorship policies at the time, all human enemies were either changed or removed in the SNES version.

• The knife throwers in levels 1-4 (Mystic Land) were changed to purple demons who spit fireballs. In the same levels, the martial artists became green-yellowish demons who throw grenades.

• The punks on level 5 (Train To Tomorrow) were changed to green robots.

• In levels 6-8 (Tokyo) the enemy who throws grenades was recolored to look like a green demon. Also, the Commando enemy in those same levels was taken out completely.
