Shazam (DC Comics) in the context of "Justice League"

A superpower is a special or extraordinary ability far greater than what is considered normal, possessed by those of superhuman status. Superpowers are typically displayed in science fiction and fantasy media such as comic books, TV shows, video games, and film as the key attribute of a superhero. The concept originated in American comics and pulp fiction of the 1930s and 1940s, and has gradually worked its way into other genres and media.

A shared universe or shared world is a fictional universe from a set of creative works where one or more writers (or other artists) independently contribute works that can stand alone but fits into the joint development of the storyline, characters, or world of the overall project. It is common in genres like science fiction. It differs from collaborative writing in which multiple artists are working together on the same work and from crossovers where the works and characters are independent except for a single meeting.

The term shared universe is also used within comics to reflect the overall milieu created by the comic book publisher in which characters, events, and premises from one product line appear in other product lines in a media franchise. A specific kind of shared universe that is published across a variety of media (such as novels and films), each of them contributing to the growth, history, and status of the setting is called an "imaginary entertainment environment".

The Golden Age of Comic Books describes an era in the history of American comic books from 1938 to 1956. During this time, modern comic books were first published and rapidly increased in popularity. The superhero archetype was created and many well-known characters were introduced, including Superman, Batman, Robin, Captain Marvel, Captain America, and Wonder Woman.

Fawcett Comics, a division of Fawcett Publications, was one of several successful comic book publishers during the Golden Age of Comic Books in the 1940s. Its most popular character was Captain Marvel, the alter ego of radio reporter Billy Batson, who transformed into the hero whenever he said the magic word "Shazam!".

Other characters published by Fawcett include Captain Video, Hopalong Cassidy, Ibis the Invincible, Bulletman and Bulletgirl, Spy Smasher, Captain Midnight, Phantom Eagle, Mr. Scarlet and Pinky the Whiz Kid, Minute-Man, Commando Yank and Golden Arrow.

Charles Clarence Beck (June 8, 1910 – November 22, 1989) was an American cartoonist and comic book artist, best known for his work on Captain Marvel (today known as Shazam!) at Fawcett Comics and DC Comics.

William Lee Parker (September 11, 1911 – January 31, 1963) was an American comic book writer and editor. He is best known for creating the Fawcett Comics character, Captain Marvel, in 1939, along with artist C. C. Beck.

Whiz Comics is an anthology comic book series that was published by former American comic book publishing company, Fawcett Publications between February 1940 until June 1953. It is widely known for being the comic run in which hugely popular superhero character Captain Marvel (Shazam) made his debut.

The Monster Society of Evil is a supervillain team created by Otto Binder and C. C. Beck for Fawcett Comics. It is led by Mister Mind against their mutual enemy Captain Marvel. The team is significant as one of the first supervillain teams in comics to contain villains that a superhero had fought previously; prior to this, supervillain teams were composed of villains created just for that storyline. In fact, the Monster Society consists of every major enemy Captain Marvel had ever faced.

The Monster Society of Evil made its debut in Captain Marvel Adventures #22, and the resulting "Monster Society of Evil" story arc continued for two years in Captain Marvel Adventures, ending with issue #46 (May 1945).

Black Adam (Teth-Adam) is a fictional character appearing in American comic books published by DC Comics. He was created by Otto Binder and C. C. Beck, and first appeared in the debut issue of Fawcett Comics' The Marvel Family comic book in December 1945. Since DC Comics licensed and acquired Fawcett's characters in the 1970s, Black Adam has endured as one of the most popular archenemies of the superhero Shazam and the Marvel Family alongside Doctor Sivana and Mister Mind.

Black Adam was originally depicted as a supervillain and the ancient magical champion predecessor of the champion Shazam, who fought his way to modern times to challenge the hero and his Marvel Family associates. Since the turn of the 21st century, however, Black Adam has been redefined by DC Comics writers Jerry Ordway, Geoff Johns, and David S. Goyer as an ancient Kahndaqi and corrupted antihero attempting to clear his name and reputation. He came from a fictional Middle Eastern country named Kahndaq, located at the southern tip of the Sinai Peninsula, and was portrayed as a hero who liberated his homeland from slavery. Featured roles in such comic book series as Justice Society of America, Villains United, Infinite Crisis, and 52 have elevated the character's prominence in the DC Universe, culminating with DC's 2021 line-wide Infinite Frontier relaunch, wherein he joins the Justice League. In 2009, Black Adam was ranked as IGN's 16th-greatest comic book villain of all time.
