Little is known about Irma other than that she was an agent of Baron Zemo, and had a reputation as one of the world’s deadliest spies. While on her way back from an espionage mission in the United States, Irma was intercepted by Sharon Carter. Carter left Irma bound and gagged in a closet and assumed her identity with the intention of replacing her in Zemo’s organization. Carter later ended up using the disguise to rescue Black Panther and Captain America, who had been taken captive by Zemo in Wakanda. It is later mentioned that a SHIELD team had free Irma from the closet and taken her into custody.
