Lady Mastermind

Regan Wyngarde, a.k.a. Lady Mastermind, (voiced by Kari Wahlgren) is one of two daughters of Jason Wyngarde, the original Mastermind. She has an intense hatred for her half-sister, Martinique (the two repeatedly insult each other).

She was originally involved in a plot created by Sebastian Shaw to have his revenge against Sage and gain control of the Sydney underworld. In an attempt to make Sage work for Shaw again, Lady Mastermind placed her in a series of illusions. However, with the assistance of Lifeguard, Sage was able to break the illusion and reflect Regan's powers back against her, leaving her in a vegetative state.
