Illusion Generation: Jason Wyngarde's sole mutant power is the generation of three-dimensional images. He has fooled such psychically powerful mutants as Professor X, Magneto, and the Phoenix (although the latter required a device which enhanced his power.) He is so skillful with his illusions that even when a character realizes that he is seeing an illusion, he will still subconsciously believe that it is real and act accordingly. Wyngarde can also make himself invisible by creating an illusion that he is not there. His illusions are visible to everyone who can see them, and include all sensory input (sound, touch, etc.) except smell, but they are not recorded on cameras, tape, or other recording mechanisms.
Mindtrap Mechanism: Frost Industries invented a device enabling Mastermind to access his target's brain directly. This "mindtap mechanism" also allowed him limited telepathy.
Nothing is known about Jason Wyngarde's life before the time when, while working as a carnival mentalist, he was enlisted by the mutant villain Magneto as a member of his Brotherhood of Evil Mutants. At this time, Magneto sought to protect his fellow superhuman mutants from the persecution of normal human beings by conquering humanity and ruling the world himself. As a member of the Brotherhood, Mastermind battled the mutant heroes of the original X-Men team.
