When Reed Richards, Sue and Johnny Storm and pilot Ben Grimm take a premature space flight on a new shuttle, they find themselves massively bombarded with cosmic radiation. Barely managing to re-enter and land safely, the quartet find themselves forever transformed with superpowers. Deciding to use these new powers to help people, they form the Fantastic Four, a superhero team dedicated to the protection of Earth from menaces like the Latverian King Dr. Doom and Galactus, the planet consumer.

Mister Fantastic, the Invisible Woman, the Human Torch, and Thing battle some of their greatest foes, including Doctor Doom, Ronan the Accuser, the Multiple Man, and Mole Man.

The first animated series based on Marvel's comic book series Fantastic Four.

The super-elastic Mr. Fantastic, the force field-wielding Invisible Girl, the orange rock-covered Thing and the data-crammed robot H.E.R.B.I.E. make up a team of superheroes dedicated to thwarting would-be world-dominating villains.
