98. Mastermind (Jason Wyngarde)

Jason Wyngarde, better known as Mastermind, was one of the more important members of Magneto's Brotherhood of Evil Mutants. The only thing known about his past, though, is that he was a mentalist at carnivals. Carnies are pretty screwed up, right?

Mastermind's powers include casting illusions causing people to psionically see, hear and even touch things that don't really exist. He can make people believe that he is another person or even invisible for that matter. He can even do this to mutants as strong as Professor Xavier and Jean Grey. Being somewhat older with graying hair, he uses these powers to appear younger and better looking.

Mastermind once helped the Brotherhood take over a whole South American country, by creating the illusion of thousands of soldiers. He was part of the Hellfire Club during the "Dark Phoenix Saga," and is basically the main person responsible for turning Phoenix into Dark Phoenix. He manipulated her into believing she was a Victorian aristocrat, married to Jason Wyngarde, and that she was Black Queen of the Hellfire Club. He then basically killed Cyclops in battle. This pissed her off and got her out of Mastermind's control. She then turned him catatonic. When he came back to his senses, he manipulated Rogue into leaving her foster mother Mystique while giving Mystique horrible nightmares. He made the X-Men think Cyclops' fianc Madelyne Pryor was the Dark Phoenix and also compelled Mariko Yashida to reject Wolverine on their wedding day.

Although Mastermind is dead, his powers live on through his daughters Martinique Jason and Regan Wyngarde who are apparently stronger than he ever was. Be afraid.
