There isn't a black female character in the original Iron Man movie (2008). The main female character is Pepper Potts, played by Gwyneth Paltrow, and she is white.
While there are other black characters in the Marvel Cinematic Universe (MCU), such as Nick Fury (Samuel L. Jackson), War Machine (Don Cheadle), and Black Panther (Chadwick Boseman), they are not prominently featured in the first Iron Man film.
The MCU has expanded its representation of diverse characters in subsequent films and shows, including the introduction of Shuri (Letitia Wright) in Black Panther and Nakia (Lupita Nyong'o) in Black Panther.
It's important to note that the question may be based on a misunderstanding or a different interpretation of the film. It's possible that the person asking the question is thinking of a different character or film altogether.
