The cunning, sinister Mastermind possessed the mutant ability to cast powerful hypnotic illusions so perfect that they were indistinguishable from reality. Even those who were aware of what Mastermind was doing were inclined to treat these images as though they were real. Mastermind frequently employed his powers for his own personal gain, often using his ability to make himself appear more handsome than he really was. He was instrumental in the transformation of the Phoenix into Dark Phoenix (see also Jean Grey). He went up against the X-Men many times, but with the exception of the Phoenix, never managed to seriously harm them. He succumbed to Legacy Virus several years ago, his death bringing an end to his years of toying with mutants and humans alike.
