Siryn (Theresa Rourke Cassidy) is a Marvel Comics superhero, associated with the X-Men.
Like her father, the X-Men's Banshee, Siryn is an Irish mutant, who possesses a "sonic scream" capable of incapacitating and injuring an opponent's hearing and sending powerful vibrations through the air. She can use these vibrations to fly. Her name refers to the Siren of Greek mythology.
Siryn was raised by Banshee’s cousin and arch-nemesis Black Tom Cassidy without Banshee's knowledge. By her early teens, she left Black Tom and joined the X-Men offshoots X-Force and X-Factor.
Created by writer Chris Claremont and artist Steve Leialoha, Siryn first appeared in Spider-Woman #37 (April 1981).
