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 hot-headed younger brother Johnny Storm, her brilliant husband Reed Richards, her close friend Ben Grimm, and her children (Franklin and Valeria).
