As Mega Man, a human-like robot created by kindly Dr. Wright (also known as Dr. Light), you must defeat six of the good doctor’s robots that were reprogrammed by the evil Dr. Wily. Upon starting, the stage selection menu shows a ring of icons depicting your foes: Bomb Man, Cut Man, Elec Man, Fire Man, Guts Man, and Ice Man. When defeated, each one of these bosses supplements Mega Man’s arsenal (initially just his arm cannon) with a unique weapon.
