Powers: Whitney is a mutant who seems to possess the ability to produce some sort of harmful toxin or poison that is deadly to those around her. How she creates and transmits this toxin (through breath, through her skin etc.) is currently unknown.
Bio: A young mutant who was taken into custody by Trask Industries after her powers manifested themselves and her parents collapsed. Apparently she produces some sort of poison that is toxic to humans around her. She was "rescued" by Mystique from Trask while she was there to break into and steal information from their server. While she was breaking into Trask to steal info from their server and rescue Whitney, Mystique poisoned the entire building, setting it up so that it looked like Whitney escaped and killed the entire building in an act of revenge.
