Background
A former pioneer in cybernetics, fallen on hard times. Throughout life, never passed an opportunity to replace inferior biological parts with their technological equivalent. As the years passed, he became more machine than man, with many costly surgeries bringing many dangerous debts. As humanity spiraled away, an indifference towards the order of law grew; the sanctity of society is meaningless compared to advancement of self.
A law enforcement Droid who faithfully surved the Empire until he was ejected from Empire ship during a rebellion breach. He became entangled in the exterior of the escaping rebellion ship. Memory units and power source were damaged beyond repair and a husk of a Droid came to rest on a planet distant from home.
Generations of mismatched technology eventually takes it's toll, and the man's mortal vessel has neared its end. While the mind that remains has become more robotic in nature, self preservation is alive as ever. A new vessel must be found, and perhaps the parts Droid he discovered holds the answer.
Thus, VN-10 is born.
