In other media Brigid O'Reilly appears in the live-action Marvel Cinematic Universe (MCU) television show Marvel's Cloak & Dagger, portrayed by Emma Lahana. Introduced in the first season, this version is a detective who formerly worked in Harlem before moving to New Orleans. She grows suspicious of her partner, corrupt police officer James Connors, which she later confirms afterward with help from Tandy Bowen. O'Reilly soon allies with Tyrone Johnson, who wants to avenge his brother's death at the hands of Connors. They succeed in getting Connors to admit his guilt and see him arrested. However, O'Reilly discovers her boyfriend was murdered. Additionally, Connors is released on suspension and proceeds to beat her in front of other officers to reinforce her outcast status among them. O'Reilly joins forces with Johnson to stop a dark energy called the Terror from being released by the Roxxon company, but is shot by Connors, exposed to the Terror's energy, and falls into a swamp, though she later re-emerges with glowing green eyes.

In the opening episodes, Mayhem proceeds to kill a number of New Orleans underworld figures, and later assumes O'Reilly's identity to take a criminal investigation into her own hands. In the meantime, Johnson finds O'Reilly tied up at home, then teleports them to Bowen, who is at a crime scene with Mayhem. Following this, Mayhem searches for Connors, killing his partner in the process. While
