In the year 20XX, Dr. Thomas Light, an Nobel Prize winning professor in the field of Robotics, creates a series of 6 revolutionary robots entitled the “Robot Master Series DRN” in an effort to use robotics as a mean to better mankind. As a personal project, Dr. Light creates 2 androids named Roll (a female) and Rock (a male) who are made to be as human as possible from appearance to behavior. His partner and colleague, Dr. Albert Wily, grows enraged and jealous of Light’s success. Dr. Wily decides to reprogram and steal the robot master series to do his bidding so he can wreak havoc and gain control of the city.
