An Irish mutant, Banshee possesses a “sonic scream,” capable of harming enemies’ auditory systems and causing physical vibrations.

A former Interpol agent and NYPD officer, Banshee was always a decade older than most of the X-Men and had only a casual relationship with the team. He was, however, a mentor of the 1990s-era junior team Generation X.

a female spirit in Gaelic folklore whose appearance or wailing warns a family that one of them will soon die

Banshees are also night elves or fairies..something to do with Warcraft..
