A nightmarish incarnation of Professor X’s dark side, Onslaught revels in manipulating the Heroes and turning them against each other. He possesses their minds with Crisis tokens, and then forces them to damage each other, or even themselves. He tricks them with illusions, making them wander around aimlessly. Also gifted with Magneto’s powers, Onslaught uses magnetism to attack any Hero who might evade his psionic reach, quickly advancing his Master Plan until he is victorious.
