When Sue Storm first found herself fading from view, she wondered if she would ever again reappear. It took her almost no time at all, however, to adjust to her newfound abilities. As the Invisible Girl, she was content to serve as a spy for the Fantastic Four, sneaking in to snatch crucial items from their enemies. Over the years, however, she has become the Invisible Woman, mother and protector of the entire group, and her power has increased proportionally. Where once she could only turn invisible and fade into the shadows cast by the Thing and Mr. Fantastic, she is now one of the most powerful superheroes in the world with might limited only by the strength of her considerable will.
