Black Noir is black in the comics. The creators have designed the character in such a way to give a specific look and feel, and the black complexion is an integral part of that design.
Weakness was a movie about the challenges and difficulties faced by boxer Jack Sully in his career, as well as his discovery of his weaknesses in matches and training. In the movie, Jack found that his key was his "fear" and "lack of confidence." By overcoming these weaknesses, he eventually became a successful boxer.
The presence of black women in noir stories is important for cultural representation. It helps to break down the narrow view of who can be a part of the noir genre. They can also offer a different view on themes like justice, morality, and power dynamics, enriching the overall narrative of the noir story.
