Dr. Elizabeth Raines used to profile for the CIA before being "killed" in a plane crash. As Sanctuary's evaluation specialist, she is responsible for determining the status of all metahuman recruits, clearing them for field duty, ordering supervision or even confining them to isolation units. She is also crosstrained as medical specialist and uses her administrative skills to supervise Sanctuary's medical staff. She tries not to get bogged down in the job, but she's seen too many messed-up people pass through her office to not feel for some of them. It takes effort to dislike her; she's either a really sweet woman or a really good actor.
Banshee has a compelling voice, implanting powerful suggestions through the sound of her voice alone. This does not constitute full mind control; it merely makes whatever she says seem profoundly true and credible. The effect can be counteracted by mental conditioning or just strong willpower, but unlike other metahuman powers, it transfers to reproductions of her voice, allowing her to use the ability via telephone or through tape recordings.
