During an expedition in space, four astronauts - scientist Reed Richards, pilot Ben Grimm, student Sue Storm and her kid brother Johnny - were bombarded by cosmic rays. After returning to Earth, the team discovered they had gained superpowers: Reed could stretch his body to incredible lengths, Ben became a super-strong being made of rock, Sue was now able to turn invisible and create force fields, and Johnny could ignite his body into flame and fly.

Dubbing themselves Mr. Fantastic, The Thing, the Invisible Woman, and the Human Torch (respectively), the quartet now explore the cosmos and fight incredible villains together as the Fantastic Four!
