The Fantastic Four (FF) are a team of adventurers who accidentally received powers from cosmic radiation during a space trip on the Marvel-1. They are Reed Richards (Mister Fantastic), Reed's girlfriend Sue Storm (the Invisible Girl, later Woman), Susan's brother Johnny Storm (the Human Torch), and their good friend Ben Grimm (the Thing). Throughout the years, the group evolved with Reed and Sue getting married, having their kids Franklin and Valeria, and members coming and going, but the original four are still the face of the FF.
