Sue Storm received her powers by being exposed to a cosmic storm, and was originally known as the Invisible Girl. She possesses two powers: invisibility and force fields. Her invisibility power deals with bending light waves and allows her to render herself and other objects invisible. She can also project powerful fields of invisible psionic, hyperspace-based energy that she uses for a variety of offensive and defensive effects, including shields, blasts, explosions, and levitation. Sue plays a central role in the lives of her hot-headed younger brother Johnny Storm, her brilliant husband Reed Richards, her close friend Ben Grimm, and her children (Franklin and Valeria). She was also romantically involved with Namor the Sub-Mariner for a time, and they remain close friends.
