The Fantastic Four is a superhero team appearing in American comic books published by Marvel Comics. The team debuted in The Fantastic Four #1, helping usher in a new level of realism in the medium. It was the first superhero team created by artist/co-plotter Jack Kirby and editor/co-scripter Stan Lee, and through this title that the "Marvel method" style of production came into prominence.

A superhero or superheroine is a stock character who typically possesses superpowers or abilities beyond those of ordinary people, is frequently costumed concealing their identity, and fits the role of the hero; typically using their powers to help the world become a better place, or dedicating themselves to protecting the public and fighting crime. Superhero fiction is the genre of fiction that is centered on such characters, especially, since the 1930s, in American comic books, as well as in Japanese media.
