Black Smurf is a fictional Smurf character associated with the Les Schtroumpfs universe, best known as a darker, more ominous variation of the classic Smurf design. Depending on the adaptation, the character may appear as a mysterious or corrupted figure rather than a regular village Smurf. In the series, Black Smurf is generally used as a visual contrast to the cheerful blue Smurfs, helping create tension, danger, or an unusual plot element.
