Siryn

Siryn (real name Theresa Maeve Rourke Cassidy) is a fictional comic book superheroine who appears in comic books published by Marvel Comics, usually those belonging to the X-Men family of titles. Debuting under the codename Siryn, she later retired the name and started using Banshee, in honor of her late father, Sean Cassidy, who first used the alias.
She was created by Chris Claremont and Steve Leialoha, and first appeared in Spider-Woman #37 in April of 1981.
==Background==
Like her father, the X-Men's Banshee, Theresa 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 Sirens of Greek mythology.
Theresa was raised by Banshee’s cousin and nemesis Black Tom Cassidy without Banshee's knowledge. By her early teens, she left Black Tom and eventually joined the X-Men offshoots X-Force and later X-Factor.
==Biography==
===Early Life===
Theresa Maeve Rourke Cassidy is the daughter of Sean Cassidy and Maeve Rourke, and Sean didn't know Maeve was pregnant when he was sent on a undercover mission. While taking her daughter to visit her family in Northern Ireland, Maeve was killed in a bombing along with other people, and Theresa was taken by her cousin Tom Cassidy. Tom believed that Theresa would develop mutant powers when she grew older, and decided to raise her to exploit her powers for himself.
===Becoming Siryn===
Theresa's powers eventually manifested once she hit puberty, and Tom tricked her into committing crimes alongside his partner Juggernaut. During her time in high school, Theresa developed a drinking problem, and didn't want to become a criminal because her heart was never in it. She was given the name "Siryn" and helped Tom and Juggernaut battle Spider-Woman and a few X-Men members, but Tom was captured. Tom decided to release Theresa of her criminal responsibility, and wrote to Sean to explain that Siryn was his daughter. Theresa and Sean united at the X-Mansion, and began to live at Muir Island run by Dr. Moira MacTaggert. During this time, Siryn began a relationship with the Multiple Man and became a member of the Fallen Angels.
