Havok is a mutant possessing the power to absorb ambient cosmic energy, process it and emanate it from his body as waves of energy that heat the air in the path, turning it into plasma in the form of a blast or discharge, with a tell-tale concentric circle pattern. These waves will emanate from his body in all directions unless he purposefully tries to channel them in a single direction, usually along the length of his arms. This results in control over an extremely powerful sort of destructive force. He is immune to the adverse effects of most forms of radiation and heat. In the past, he was not entirely able to control this ability, which made him a danger to those around him unless he wore a special containment suit equipped with special sensors for measuring and controlling his power output.
