Four young outsiders - Reed Richards, Sue Storm, Johnny Storm, and Ben Grimm - are transported to an alternate universe. There, they gain superhuman powers, dramatically altering their physical forms in shocking ways. Reed becomes Mister Fantastic, with the ability to stretch his body to incredible lengths; Sue transforms into the Invisible Woman, capable of becoming invisible and generating force fields; Johnny ignites as the Human Torch, controlling and generating fire; and Ben morphs into The Thing, endowed with immense strength and a rock-like exterior.
