Robert Sand, the Black Samurai, is an agent for the President.
At the age of 21, Robert Sand was a young army private on R&R in Japan from his first tour in Vietnam when he came upon several drunk American soldiers harassing a elderly man. After receiving two gun shot wounds for his troubles while trying to help the man, Sand soon realized that defenseless was not a word to use for the aged gentleman.
Konuma was the man's name and he was a Master samurai training a small group to continue the ancient traditions. Seeing something in the selfless act, Konuma used his considerable influence to have Sand released from the army and sent to his encampment where he was offered instruction.
For seven years, Sand studied diligently the honorable ways of the samurai, including an almost unlimited number of ways of fighting. From bare hands through knives and arrows and sticks and throwing stars to the modern rifle, Sand and his new brothers learned how to defend themselves and how to take a war to others.
During this long period of training, Konuma introduced Sand to William Baron Clarke, a former President of the United States as well as being an extremely rich man who worried considerably about the rise in evil around the world. It was Clarke's wish that Sand join his struggle to right the wrongs no matter where they were found. Though intrigued, Sand elected to stay with his Master until the old man died or sent him away.
When the former happened and Sand was left without an anchor, he turned to the demanding world leader and became his strongest weapon in the fight against tyranny and terrorism.
