Originally called Invisible Girl, Susan Storm is the heart and soul of the Fantastic Four as Invisible Woman, older sister to Johnny Storm and wife to Reed Richards. The first female super hero to emerge from comic books’ Silver Age, Susan Storm gained her powers in the same cosmic radiation accident that saw the creation of Mr. Fantastic, The Human Torch and The Thing.
Her ability consists of bending light waves around her, turning her invisible to the naked eye. However, in addition to this, she can advance this invisibility over other objects, as well as project and create powerful invisible “force” objects that can act both as a shield or as a weapon.
In the beginning her passive powers made her the damsel in distress, meaning she became the hostage in all the early adventures, before learning of her potential and going on to be one of the more powerful heroines in the Marvel Universe.
