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.
Operatives contacted Robert on behalf of Lex Luthor, who saw him as a pawn to be used in Superman's assassination. Under the direction of a man named Kimberley, the operatives of Luthor played upon Dubois' fixations with Vietnam to condition him psychologically into wanting to kill Superman. They also equipped Dubois with an arsenal of advanced scientific weapons, including a gun that fired needles of Kryptonite. Calling himself Bloodsport, Dubois went to Metropolis, claiming both he and his brother had seen action in Vietnam and that they had both been wounded out there. Professing anger at Metropolis's citizens for the way they were "wasting" the freedom that he and his brother had fought to earn, Bloodsport began to indiscriminately shoot into the crowd, killing dozens of innocent people.
In his first clash with Superman, Bloodsport wounded the Man of Steel with his Kryptonite needle gun. However, Jimmy Olsen managed to save Superman's life, holding Bloodsport at gunpoint until he escaped. After receiving medical attention, Superman returned to the fray. Even Luthor was outraged at Bloodsport's murder of so many innocent people, and he too tried to stop the crazed killer. Superman managed to cause Bloodsport's teleportation device to malfunction, meaning the villain had no more access to his weapons. Bloodsport then threatened to detonate his power pack, potentially eradicating 10 square miles of the city.
However, Jimmy Olsen had managed to track down Michael Dubois, and the paraplegic managed to convince his brother to lay down his weapons.
The third Bloodsport has teamed with Hellgrammite and Riot. No other information has been revealed.
