Siryn is a superhero in the Marvel Comics universe, best known as a member of the X-Men offshoot X-Force. Like her father, the X-Men’s Banshee, Siryn (real name Theresa Rourke) is an Irish mutant, who possesses the ability to fly and a "sonic scream" capable of injuring an opponent's hearing and sending powerful vibrations through the air. Her name derives from the sirens of Greek mythology.

Comic book history

Created by Chris Claremont and Steve Leialoha , Siryn first appeared in Spider-Woman #37 (April 1981) as an apprentice of the super villains Black Tom Cassidy and Juggernaut. It was later revealed that her father, Banshee, knew nothing of her existence and she was raised by his cousin and arch rival Black Tom after the death of her mother.

Eventually, Theresa accompanied Black Tom and his partner, the Juggernaut, to San Francisco to assist him in his crimes. Here, employing the name Siryn, she battled the original Spider-Woman and several of the X-Men. This conflict ended in Black Tom's temporary capture. While in custody, Black Tom exonerated Theresa of responsibility for her crimes and wrote a letter to Sean explaining who she was. The X-Men brought Theresa back to their headquarters, where she was joyfully reunited with her father.

Throughout the 1990s, Siryn was a member of X-Force, a platoon-like superhero team and for a time was its field leader. As a member of X-Force, she developed a relationship with her teammate Warpath and a flirtation with the mutant mercenary Deadpool. She left in 1998, when Feral , a former teammate gone bad, slashed her throat, destroying her vocal chords - rendering her mute and powerless.

Thanks to the aid of Deadpool, Siryn has since fully healed and currently is a member of the Paris branch of the international mutant task force X-Corporation .

Appearance in X2

In both the 2000 X-Men film and its 2003 sequel X2: X-Men United, several X-Men characters made cameo appearances as young students at Xavier’s School for Gifted. In X2, actress Shauna Kain portrayed a red-haired mutant who belted out a glass-shattering scream, generally believed to be Siryn.
