Doctor Strange in the context of "Steve Ditko"

A superhero or superheroine, is a 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 (and later in Hollywood films, film serials, television and video games), as well as in Japanese media (including kamishibai, tokusatsu, manga, anime and video games).

Superheroes come from a wide array of different backgrounds and origins. Most superheroes (for example, Superman and Spider-Man) usually possess non-human or superhuman biology, while others (such as Batman and Iron Man) derive their status from advanced technology they create and use, but some of them may use or possess objects that have superhuman, mystical, or alien powers (such as Green Lantern and He-Man), or study and practice magic to achieve their abilities (such as Doctor Fate and Doctor Strange). The Dictionary.com definition of "superhero" is "a figure, especially in a comic strip or cartoon, endowed with superhuman powers and usually portrayed as fighting evil or crime," and the Merriam-Webster dictionary gives the definition as "a fictional hero having extraordinary or superhuman powers; also: an exceptionally skillful or successful person." Terms such as masked crime fighters, costumed adventurers or masked vigilantes are sometimes used to refer to characters such as the Spirit, who may not be explicitly referred to as superheroes but nevertheless share similar traits.

Stan Lee (born Stanley Martin Lieber /ˈliːbər/; December 28, 1922 – November 12, 2018) was an American comic book writer, editor, publisher and producer. He rose through the ranks of a family-run business called Timely Comics which later became Marvel Comics. He was Marvel's primary creative leader for two decades, expanding it from a small publishing house division to a multimedia corporation that dominated the comics and film industries.

In collaboration with others at Marvel – particularly co-plotters and artists Jack Kirby and Steve Ditko – he co-created iconic characters, including Spider-Man, the X-Men, Iron Man, Thor, the Hulk, Ant-Man, the Wasp, the Fantastic Four, Black Panther, Daredevil, Doctor Strange, the Scarlet Witch, and Black Widow. These and other characters' introductions in the 1960s pioneered a more naturalistic approach in superhero comics. In the 1970s, Lee challenged the restrictions of the Comics Code Authority, indirectly leading to changes in its policies. In the 1980s, he pursued the development of Marvel properties in other media, with mixed results.
