Banshee

Banshee is a fictional superhero appearing in American comic books published by Marvel Comics, commonly in association with the X-Men. Created by writer Roy Thomas and artist Werner Roth, the character first appeared in X-Men #28. 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. He was 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.
