Susan "Sue" Storm Richards (also known as Invisible Girl and later, Invisible Woman) is a fictional character, a Marvel Comics superheroine created by writer Stan Lee and artist/co-writer Jack Kirby. The character first appeared in Fantastic Four #1 in November 1961, and was the first female superhero created by Marvel in the Silver Age of Comics. Like the other founding members of the Fantastic Four, Sue received her powers after being exposed to a cosmic storm. Her primary power deals with light waves, allowing her to render herself and others invisible. However, she can also project powerful fields of invisible psionic energy which she uses for a variety of offensive and defensive effects. Sue plays a central role in the lives of her brother, her husband, her children (Franklin Richards and Val Richards), and her friend, Ben Grimm.
