Strength Level: The Purple Man possessed the normal human strength of a man of his age, height, and build who engaged in no regular exercise.
Known Superhuman Powers: The Purple Man possessed the superhuman power to sap people's wills, making him able to command people by simple verbal suggestion. His power originated in his skin cells, which had been mutagenically altered by impregnation by an unknown, experimental form of nerve gas. The nerve gas was abnormally active due to its great concentration in liquid form. The sites of pheromone production and other secretions in the Purple Man's deep dermis produced nervous psychoactive chemicals which, when inhaled or absorbed through the skin, induced in his victims an overwhelming monomania that rendered him or her completely without a will of his or her own. Only a very few individuals proved capable of resisting the Purple Man's will-sapping power.
The Purple Man could simultaneously subjugate as many people as were present within the range of the psychoactive chemicals he exuded. He was known to enthrall crowds of over 100 people. Ordinarily, the effects lasted only as long as the Purple Man was physically present. When he departed, the level of psychoactive chemicals within his victims were reduced at various rates (dependent upon their metabolisms), and thus the victims regained command of their own wills.
The Purple Man was a charismatic individual, with an entrancing lilt to his speech that he cultivated over his adult life and that he used in exercising his superhuman power. While using his power he often engagingly asked strangers to do incongruous or even foolhardy activities, which they performed without question.
Weapons: The Purple Man's underlings in his criminal organization employed a purple will-deadening gas to overcome victims in their employer's absence. The gas was a derivative of the same chemicals that gave Killgrave his superhuman power.
