Regan Wyngarde (Earth-513)

Early life
Regan Wyngarde - or Lady Mastermind, as she calls herself - is one of three daughters of Jason Wyngarde, the original Mastermind and mutant terrorist. She has an intense hatred for her half-sister, Martinique. She is hated by her sister for "stealing the spotlight", while she hates her sister for being a "skank", with the two of them constantly insulting each other. Before Regan came to MHS, she went to the same school as Martinique, but got kicked out after one of their fights got out of hand.

Character
Regan can be described as a bit of an exuberant sociopath, with a volatile and extreme personality. You might suspect that some aspects of her behavior may have their roots in an actual psychosis, but on the surface she's just a wickedly ingenious, endlessly aggressive girl who never lets anyone get away with anything. She's arrogant, snobbish and spoiled.

She is very much a Daddy's girl and followed in her father Jason's footsteps when it comes to her backstabbing, ruthless and manipulative ways. But she has developed a bit of a darker streak when she found out her illusions could hurt and even kill people. Her mind runs free when she finds a person she wishes to torment.

At school, she's known as "The Bitchy Blonde" or "Queen Bitch", never shy of making snarky comments or picking a fight.

Abilities
Regan 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 has. Her half-sister Martinique has roughly the same powers. 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 brainwashing tool. In addition, unlike her father Regan has limited telepathic abilities that enable her to read her foes minds and make her illusions all the more accurate. Regan's illusions have also been shown to persist even after she has been rendered unconscious.

Also, her illusions can put enemies in a coma like state, by telepathically putting her enemy's mind in a maze in which theres no escape. Regan's powers can also kill, as her victims bodies respond as if her illusions were real.
