Lady Mastermind

Regan Wyngarde is the daughter of the original Mastermind and inherited his potent illusion-casting abilities. Debuting in X-Treme X-Men #8, she carved out her own villainous identity, wielding powerful telepathic illusions to manipulate and deceive those around her.

Debuting in X-Treme X-Men #8 in 2002 under the masterful hands of Chris Claremont and Salvador Larroca, Lady Mastermind is one of the Modern Age's most intriguing additions to Marvel's mutant mythology — a figure steeped in illusion and danger who has haunted the X-Men's world for over two decades. She's carved out her niche across titles like X-Men and Dark X-Men: The Mercy Crown, keeping wickedly compelling company alongside the likes of Mystique and Nightcrawler. With 22 years of appearances and a presence that spans some genuinely charged corners of the X-universe, she's the kind of character that rewards the curious reader willing to dig into the shadowy edges of the X-Men's sprawling saga.
