Power limitation

Power limitation is the act of possessing a powerful ability or abilities, but having restrictions and limits to one's power. Luke Sherman has this weakness, as he possesses the ability to heal rapidly from wounds, injuries and diseases, but cannot recover from decapitation, unless his head is put back into place. Jared Whiteman also has this weakness, as his body requires cosmic energy to keep him alive, because his living functions do not operate like a human's does (food, water, oxygen and sleep).
