Dr. Susan "Sue" Richards (née Storm), a.k.a. the Invisible Woman, is an American superpowered adventurer. She was a college student before she was exposed to high levels of cosmic radiation when boyfriend and scientist, Dr. Reed Richards, took her with her younger brother, Johnny Storm and pilot Ben Grimm, into space in the stolen rocket Marvel-1. The radiation mutated her and her friends, turning her invisible and allowing her to create forcefields. Together they became the Fantastic Four, a team of adventurers who explored space, time, and alternate dimensions and saved the world along the way from science-based threats.
