Banshee

Summary of Character
Banshee (Sean Cassidy) is a fictional character, a superhero who appears in comic books published by Marvel Comics. He operates as a member of the X-Men. Created by writer Roy Thomas and artist Werner Roth, the character 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. He is named after the banshee, a legendary ghost from Irish mythology, said to possess a powerful cry, although the banshee spirit is invariably female and the Irish Gaelic to English translation of Bean Sidhe (Banshee) is literally Fairy Woman, making it an odd choice for a male character (the male version is Fear Sidhe).

A former Interpol agent and NYPD 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, however, a mentor of the 1990s-era junior team Generation X. Caleb Landry Jones played the role of Banshee in 2011's X-Men: First Class.
