While speaking with the press today, including CBR, "Supergirl" executive producer Andrew Kreisberg revealed James Olson -- played by Mehcad Brooks on The CW program -- will soon be bit by the hero bug and become The Guardian.

"James will decide he can no longer sit back and be a sidekick," the producer said. "[It] will cause massive problem in his relationship with Kara because he has decided not to tell her."

With Kara unwilling to support vigilantes, there will be a "push-pull" between Supergirl and the Guardian.

Calling the development an "interesting career trajectory," Kreisberg revealed James will also recruit Winn (Jeremy Jordan) into his new crusade. "Winn is his man in the van. Putting Winn and James together is like comedy gold." Winn will also keep his involvement secret from the DEO and have to explain "why he walks in exhausted, and why he has a black eye."

Originally created by Jack Kirby and Joe Simon, the original Guardian was Jim Harper, a police officer assigned to Metropolis's Suicide Slum. Tired of seeing criminals evading justice, he took on the role of a costumed vigilante. With the aid of the Newsboy Legion, he took on criminals with his fists and a badge-shaped shield.

Though it is unclear if the Newsboy Legion will appear, Kreisberg said James' Guardian will use the character's shield.

The Jim Harper Guardian does have ties to the Cadmus Project, with his original Newsboys becoming the project's original founders. But it is unknown if that detail will find its way into the origins of "Supergirl's" Cadmus. Later incarnations of the hero included former Teen Titan Mal Duncan, who utilized an exoskeleton to provide him with super strength, and Jake Jordan, who was actually known as the Manhattan Guardian. Unlike Harper, both of those characters are Black rather than Caucasian.

Starring Melissa Benoist as the Girl of Steel, "Supergirl" airs Mondays at 8 pm ET/PT on The CW. The series also stars David Harewood as Martian Manhunter, Mehcad Brooks as Jimmy Olsen, Chyler Leigh as Alex Danvers and Jeremy Jordan as Winn Schott and features appearances by Calista Flockhart's Cat Grant as well as Tyler Hoechlin's Superman.
