While working as a carnival mentalist, Jason Wyngarde was enlisted by Magneto to serve as member of the original Brotherhood of Evil Mutants. Magneto sought to protect his fellow mutants from persecution by conquering humanity and ruling the world himself. As Mastermind, Wyngarde helped the Brotherhood in pursuit of this goal. Magneto employed him to use his illusionary powers to re-write Lorna Dane's memories of the revelation that she was his daughter. Lorna was led to believe that her parents died in a plane crash, when she was an infant. Magneto believed that she was not ready for her abilities, or for the life that he could offer her.[2] With his teammates Toad, Scarlet Witch, and Quicksilver, the Brotherhood battled the original X-Men repeatedly, but the X-Men continually thwarted them.
