Fan Casting Bloodsport in DC Characters

During the Vietnam War, Robert DuBois was drafted into the US armed forces. Upon receiving his induction notice, DuBois fled to Canada, not because he had a moral objection to war, but because he was afraid of dying. Dubois' younger brother Michael reported for induction in his place, passing himself off as Robert. Michael DuBois was sent into combat in Vietnam, where he lost both his arms and legs. On learning of his brother's lost limbs, Robert DuBois went insane through guilt. He spent years in and out of psychiatric hospitals in Canada and became obsessed with the Vietnam war.
