In the year 200X, robots developed to assist mankind are commonplace thanks to the efforts of renowned robot designer Dr. Light. However, one day these robots go out of control and start attacking the populace, among them six advanced humanoid robots made by Dr. Light for industrial purposes: Cut Man, Guts Man, Ice Man, Bomb Man, Fire Man, and Elec Man. He realizes the culprit is his old rival Dr. Wily (who plots to take over the world), but is unsure of what to do. His helper robot Rock, having a strong sense of justice, offers to be converted into a fighting robot to stop Dr. Wily's plan, becoming Mega Man.
