Sue Storm/The Invisible Girl
In the comic book, Sue and her brother Johnny have a happy childhood until their mother, Mary, dies in a car accident. Their father becomes distraught with grief and his life spirals out of control. Sue and Johnny live with their aunt, Marygay, who runs a boarding house. Sue meets Reed Richards when Reed is staying at their house, and she soon develops a crush on him. When Sue grows up and goes to college, she dates Reed. Sue joins Reed's crew on his failed expedition, and as a result of radiation exposure, she discovers she can turn invisible and create force fields. Sue and Reed get married, and eventually Sue has two children with Reed -- Franklin and Valeria. While in the early comic books Sue is a rather passive character, in more recent issues she has become much more assertive.
