“Supergirl”’s James Olsen is sick and tired of playing second fiddle to a certain pair of Kryptonian crime fighters. The photographer left Metropolis behind in order to become his own man, and he’ll continue his quest for independence as Guardian.

'Supergirl' introduces Guardian

That’s right, folks, Mehcad Brooks’ DC character will take on his own superhero mantle this fall. Unfortunately for the rest of the “Supergirl” gang, James will decide to keep his vigilante pursuits under wraps.

“James is going to decide that he can no longer be a sidekick, so he’s going to become a vigilante,” executive producer Andrew Kreisberg explained told TVLine.

“He’s going to become Guardian, complete with the shield, which is going to cause a massive problem in his relationship with Kara because he decides not to tell her. There’s this new masked vigilante, and she has her own feelings about vigilantes.”

Too bad Kara (Melissa Benoist) gave her pal the old heave-ho on the romantic front. Otherwise, National City could have a couple working in tandem to tamp down the alien threats the universe keeps lobbing their way.

Who will know Guardian's secret?

Although James can’t exactly confide his day-to-day adventures to his CatCo colleagues, there will be one person at the Department of Extranormative Operations who will have his back. Winn (Jeremy Jordan) proved his worth to Henshaw (David Harewood) in the season 2 premiere, and his upcoming job at the DEO will place him in a prime position to become James’ go-to man.

“He’s recruited Winn to help him,” Kreisberg teased. “Winn is his man in the van. Winn and James together is like comedy gold.”

But how will Kara react when she learns the truth? Could James’ secret put the final nail in the pair’s deferred romance? For now, everyone on “Supergirl” is just looking to hone their identities…alone.

“Really this year is about coming into one’s own and becoming who you are,” Kreisbergexplained to Entertainment Weekly. “In a way, all of the characters are dealing with that.”
