In the twenty-first century, the world enjoys a brief period of peace thanks to the efforts of the super robot Mega Man. Dr. Wily claims he is a changed man, reforming and teaming up with Dr. Light to develop a giant "peace-keeping" robot named Gamma. It was the lifelong dream of Dr. Light to create a giant robot to protect and serve world peace. With their research almost complete, all that remained was to combine eight Energy Elements that were scattered about uncharted planets and bestow them to Gamma. For some reason, the newest Robot Masters created by both doctors to mine the energy elements suddenly have gone crazy. Dr. Light needs the eight Energy Elements that the robots are protecting for the creation of Gamma, thus, when Mega Man learns about the incident, he and Rush set out for the uncharted planets to stop the robots and retrieve the energy elements.
