Lady Mastermind

Regan Wyngarde (codename Lady Mastermind) is a member of the Brotherhood of Mutants.

Powers
Telepathic Illusions: Lady Mastermind possess 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 (for example, Rogue, when under Lady Mastermind's control did not question the sudden existence of a multitude of Vargases, or the random jumps in location and time she was experiencing). As such they can be used as a very effective brainwashing tool. In addition, unlike her father, both Regan and her half-sister Martinique have limited telepathic abilities that enable them to read their foes minds and make their illusions all the more accurate for it. Regan's illusions have also been shown to persist even after she has been rendered unconscious.
 * Psychosomatic Symptoms: Regan's powers can also kill, as her victims bodies respond as if her illusions are real. She confronted Viceroy 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. Heather Cameron's body also responded in a similar way, bleeding through the pores in her back when she was under the illusion she had been stabbed.
