Lady Mastermind
Regan Wyngarde
Daughter of the original Mastermind, Regan inherited her father's illusion-casting abilities at even greater potency. Her psychic illusions can cause real physical pain and even death. She served with the Marauders and later joined Rogue's X-Men squad during Mike Carey's run, though her loyalties always remained suspect.

Lady Mastermind remains a compelling but underutilized character whose illusion powers and morally complex nature make her stand out among the crowded roster of telepaths and illusionists. Her appearances in Mike Carey's X-Men run and as part of the Sisterhood of Mutants showcase her at her most effective, blending her father's legacy with her own ruthless ambition. While she hasn't achieved the iconic status of other psychic characters, her rare appearances tend to leave an impression when writers lean into her manipulative, femme fatale persona.
