The Fantastic Four

The Fantastic Four is a fictional superhero team appearing in comic books published by Marvel Comics. The group debuted in The Fantastic Four #1 (November 1961), which helped to usher in a new level of verisimilitude in the medium. The Fantastic Four was the first superhero team created by writer-editor Stan Lee and artist and co-plotter Jack Kirby, who developed a collaborative approach to creating comics with this title that they would use from then on. As the first superhero team title produced by Marvel Comics, it formed a cornerstone of the company's 1960s rise from a small division of a publishing company to a pop-culture conglomerate.
