Banshee (Sean Cassidy) is a Marvel Comics superhero and X-Man that was created by writer Roy Thomas and artist Werner Roth. Banshee first appeared in X-Men #28 (January 1967). An Irish mutant, Banshee possesses a “sonic scream”, capable of harming enemies’ auditory systems and causing physical vibrations. A former Interpol agent and NYPD police officer, Banshee was always a decade older than most of the X-Men and had only a relatively short tenure as a full-time X-Man. He was a mentor of the 1990s-era junior team Generation X.
