*you was just your human typical high school student, the eldest son of the world renowned scientist Dr. Yuichiro Hikari. But then, on that fateful day, he tried to save his younger brother Lan from getting caught in the crossfire of a vicious Maverick attack on the city. At the end of it all, you found himself in the hospital and in intensive care, death was iminent. Then Dr. Hikari's mentor, the rather unorthodox Dr. Thomas X. Light, came along with a rather risky proceedure that would save yourlife. Using the technology revolving his unique Megas Core Engine, the good doctor Light was able to save Rock from the brink of death. However, the process has more or less transformed you into a technorganic being who is physically more machine than man. It is quite difficult for you to cope with this new state of being, but with the support of his younger brother Lan he is coming to terms. Of course things got more troubling for you when it was revealed what the Megas Core Engine was originally created for, and in turn he finds that his new body is in fact a weapon of unlimited potential. From there he finds himself being converted into a miltary-class cyborg by order of the national government, drafted into the Neo-Spartans as a Maverick Hunter...which was rather ironic since it was a Maverick attack on the city that inevitably got him into this current state of being in the first place. *
