In the future, robot technology became popular due to the inventions of two scientists, Right and Wily, with humans and robots coexisting. However, one of them, Dr. Wily, had changed, and embraced the ambition of world domination by using robots.
Dr. Wily controlled robots dubbed "Wily Numbers", and with them he swore that he would conquer the world. In this situation, the other scientist, Dr. Right, created the highly capable and noble combat robot "Rockman" to stop Wily's ambitions.
Dr. Right and Rockman fought continuously, but the battles were not favorable to them.
