Sonic Lance: By focusing her sonic vibrations while screaming into an intense beam. This is used as a sort of "battering ram" that can stun or even destroy most solid objects.

::Other::Short Bio: Theresa Cassidy is the mutant daughter of Sean Cassidy, the mutant who was to become known as the Banshee, and Maeve Rourke. Soon after his marriage, Sean Cassidy, an Interpol agent, was sent on an undercover anti-terrorist mission for many months, not knowing when he left that Maeve was pregnant. Shortly after Theresa's birth, Maeve was killed in an IRA (Irish Republican Army) bombing along with a number of other people. Those who knew of Theresa's existence assumed that she too had been killed in the explosion and never told Sean Cassidy that Maeve had had a daughter. Sean was so filled with anguish when he returned and learned of Maeve's death that he left his ancestral home of Cassidy Keep and threw himself into a series of highly dangerous missions in order to lose himself in his work. Eventually this led to his resignation from Interpol and his later involvement with the mutant villain team Factor Three and then the hero team X-Men.
Unknown to Sean, the baby Theresa had been found after the explosion by his cousin Black Tom Cassidy who, suspecting that she might be a superhumanly powered mutant as he himself and her father were, decided to raise her secretly himself. Theresa's sonic powers emerged at puberty, and a few years later Black Tom began coercing her aid in committing crimes. At one point during high school, Theresa developed a drinking problem.
However, Theresa's heart was never in a life of crime, and she pursued it because the man who raised her, Black Tom, ordered her to do so. Eventually Theresa accompanied Black Tom and his partner the Juggernaut to San Francisco. There, employing the name Siryn, she battled the original Spider-Woman heroine and several of the X-Men. This conflict ended in Black Tom's temporary capture. While in custody, Black Tom gentlemanly exonerated Theresa of responsibility for his crimes and wrote to Sean explaining who she was. Theresa went to live with her father, who had since retired back at Cassidy Keep.
Sometime afterward, Theresa lived for a while at the Muir Island mutant research facility owned by scientist Moira MacTaggert. There she met and developed a romantic relationship with Jaime Madrox a.k.a. the Multiple Man. At one point, she and Madrox helped to track down the young mutant Sunspot, which led to the mutants joining briefly the group known as the Fallen Angels at the behest of the mind-altering alien Ariel. Once Ariel's scheme was discovered, the Theresa, Madrox, and Sunspot returned to their respective homes.
Later, Theresa learned of an attempt by Black Tom and the Juggernaut to bomb the World Trade Center in New York, and she joined the formative group of mutants known as X-Force in defeating them. She remained alongside the team for a long tenure, and eventually grew to become Field Leader during the absence of their former leader, Cable. On a solo adventure, Theresa encountered the mercenary Deadpool when both were tracking down activities of Black Tom. The two developed romantic feelings toward one another, but parted company.
