Regan Wyngarde

Telepathic illusions: Wyngarde possesses the mutant power to project extremely convincing and realistic illusions into the minds of others, a stronger variation of the same ability her father had.

Her illusions are hypnotic and her victims tend to accept them as fact even when the images and scenarios they are confronted with involve sudden changes to the world around them or are inconsistent or improbable. As such, they can be used as a very effective brain-washing tool. In addition, unlike her father, both Wyngarde and her half-sister have limited telepathic abilities that enable them to read their foe's minds and make their illusions all the more accurate. Wyngarde's illusions have also been shown to persist even after she has been rendered unconscious.
 * Psychosomatic symptoms: Wyngarde's powers can also kill, as the bodies of her victims respond as if her illusions are real. She confronted an enemy with the illusion that he was drowning and, believing it to be real, he suffocated despite having no physical injuries and being in a room with sufficient oxygen.
