[1][2][3] The Robert DuBois incarnation of Bloodsport made his live-action debut in the television series Supergirl, played by David St.

[6][7] The second incarnation, Alexander Trent, made his first appearance in The Adventures of Superman #507 (December 1993) and was created by writer Karl Kesel and artist Barry Kitson.

[8] The third incarnation, known as Bloodsport III, made his first appearance in Superman #652 (July 2006) and was created by writers Kurt Busiek and Geoff Johns, and artist Pete Woods.

[20] Operatives of Luthor, under the direction of a man named Kimberley, played upon DuBois' fixations on Vietnam to condition him psychologically to want to kill Superman.

[23] Professing rage at the citizens of Metropolis for wasting the freedom he claimed both his brother and himself fought to defend, Bloodsport indiscriminately slaughtered dozens of innocent people.

Even Luthor, outraged by Bloodsport's murders of so many people due to the attention this would attract to his assault, attempted to stop the mad killer.

[33] As racial tension began to overwhelm Stryker's Island, the prison warden decided to host a boxing match between DuBois and Trent.

After failing to kill Superman, he was sent to Belle Reve until he was forced into the Suicide Squad with the task of exploring the Multiverse for Amanda Waller's own personal ambitions.

[41] Some time later, in an effort to provide an outlet for rising tensions at Stryker's Island Prison, a boxing match between the two Bloodsports is organised.

[46][43] An unnamed person took up the mantle of Bloodsport, and eventually teamed up with Hellgrammite, Silver Banshee, Kryptonite Man, Toyman, Puzzler, Livewire and Riot to take on Superman.

[48][49] After these events, Bloodsport turned up in the crowd of villains transported to another planet in Salvation Run;[50] and to be a quickly defeated menace by Guardian.

[55] While Robert DuBois has no superhuman powers, he has proven to be a formidable hand-to-hand combatant when needed due to his excellent physical condition and his fearlessness as a fighter.

[56] He's in possession of a device that enables him to teleport high-tech weaponry to him from a distant location instantaneously, with many being one-of-a-kind prototypes from advanced LexCorp research projects.
