Johnny Storm / Human Torch: Following his sister, Sue Storm, Johnny joined Reed Richards' crew in a fateful flight into space in which the crew was riddled with cosmic radiation. Crash-landing back on Earth, Johnny burst into flames - but was not consumed by the flames. Calling himself the "Human Torch" in tribute to the World War II-era hero of the same name, the youthfully Johnny Storm found new adventures as part of the Fantastic Four, proving to be an invaluable, if somewhat volatile member of the team.
Ben Grimm / The Thing: In College at State, Ben Grimm roomed with Reed Richards, who dreamed of someday building a starship; Grimm jokingly promised that if Reed ever built it, he would fly it. After his time at State, Reed had begun to build his starship, and asked his old friend to be its pilot. Initially Ben feared that the ship might not be adequately shielded against cosmic radiation; but he acquiesced. As Ben had feared, cosmic rays penetrated their shielding and forced them to crash-land back on Earth. Due to his exposure to the cosmic rays, Ben Grimm was transformed into the monstrous, rock-hided strongman dubbed "The Thing."
