What group of space pirates does Kara briefly fight before learning Krem's location?

The space pirates Kara briefly fights before learning Krem’s location are the Sklarian Raiders.

The Sklarian Raiders are an all-female pirate group from DC’s cosmic corner, and they appear during Kara and Ruthye’s search for Krem. Their encounter is a short but important detour: the confrontation gives the travelers information that helps point them toward Krem’s whereabouts.

The group originated in Legion of Super-Heroes stories rather than in Superman’s traditional Earthbound supporting cast. They come from Sklaria and turned to piracy after their society was damaged by political and technological upheaval. Their comic-book history includes raids for advanced equipment and other valuable technology.

The Raiders are easy to confuse with other spacefaring groups in the film’s wider DC setting. The Ravagers are associated with Marvel’s Guardians of the Galaxy, while Red Lanterns are an emotion-powered corps from DC. “Brigands” is also used for another criminal group in the story, but it is not the name of the pirates Kara encounters in this scene.
