Banshee (X-Men)

An Irish mutant, Banshee possesses a "sonic scream", capable of harming enemies’ auditory systems and causing physical vibrations. He is named after the banshee, a legendary ghost from Irish mythology, said to possess a powerful cry. 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.
