| Real name: Theresa Rourke, a.k.a. Theresa Rourke Cassidy Occupation: (current) Adventurer, (former) Professional criminal Group affiliation: X-Men Base of Operations: Xavier Institute for Higher Learning, Westchester County, New York Height: 5'6" Weight: 112 lbs. Eyes: Blue Hair: Reddish Blonde Powers: Siryn is a mutant who has the ability to create various sonic effects through the combined action of her vocal cords and limited psionic powers which can only be used in conjunction with the sounds she produces. She inherited these powers from her father, who has the same abilities. By focusing her sonic vibrations into an intense beam, Siryn creates what she calls her "sonic lance," which can shatter any known solid substance except adamantium and vibranium. Siryn can use her "sonic lance" at a lower intensity to stun people into unconsciousness without doing them injury. Siryn can use the sonic vibrations of her scream to propel herself through the air. Although it might be expected that emitting sound waves from her mouth would propel Siryn backwards, since for every action there is an equal and opposite reaction, this is not the case. Siryn's psionic abilities cause the acoustic energy to flow behind her. Siryn's psionic abilities enable her while in mid-flight to temporarily stop screaming to speak or to employ her scream to perform other sonic feats. Siryn can also use her sonic powers as a form of sonar (Sound Navigation And Ranging). Siryn's vocal cords and the interiors of her throat and mouth are superhumanly tough, so that the intense pressures and constrictions that she produces do not cause her any injury. While using her sonic powers Siryn also automatically and psionically creates a force field that protects her body from the destructive effects of the sound she creates. The force field only protects Siryn against her own sonic vibrations and nothing else, and can only be activated when she is using her sonic powers. Weapons: None |
