His backstory is that his an highly trained assassin with an metal arm. When need it he will reshape the history to suffice the government. And when not need it he will be put on ice for the next time the government will need the assassin to reshape things to there liking.
As for the metal arm how he got it, is really simple, he had an accident on a special mission, he succeeded but with the cost of his arm.
