In the 1960s, The four astronauts traditionally associated with the Fantastic Four, who gained superpowers after exposure to cosmic rays during a scientific mission to outer space, are: Mister Fantastic (Reed Richards), a scientific genius and the leader of the group, who can stretch his body into incredible lengths and shapes; the Invisible Woman (Susan "Sue" Storm-Richards), Reed's girlfriend and later wife, who can render herself invisible and project powerful invisible force fields and blasts; the Human Torch (Johnny Storm), Sue's younger brother, who can generate flames, surround himself with them and fly; and the monstrous Thing (Ben Grimm), their grumpy but benevolent friend, a former college football star, Reed's college roommate and a skilled pilot, who possesses tremendous superhuman strength, durability and endurance due to his stone-like flesh.
