Justice Society of America in the context of "Gardner Fox"

Doctor Fate (also known as Fate) is a superhero who appears in American comic books published by DC Comics. Created by Gardner Fox and Howard Sherman, the character first appeared More Fun Comics #55 (May, 1940) during the Golden Age of Comic Books. Since his creation, several other characters have served as successor incarnations of the character within the mainstream DC Universe as legacy heroes, with each new version attempting to reinvigorate the character for contemporary audiences. As the original, he is sometimes also referred to as the Golden Age Doctor Fate.

The original character's secret identity is archaeologist Kent Nelson who encountered a cosmic being named Nabu, a member of the Lords of Order, while accompanying his father in an archaeological expedition during his youth. Unwittingly leading to his father's death upon releasing Nabu, the cosmic being pities him and raises him as a sorcerer although various retellings differ in Nabu's intentions and how Nelson is trained. Gifted the Helmet of Fate and several other artifacts, he becomes the hero and agent of the Lords of Order, Doctor Fate. A major character featured in titles based upon several teams such as the Justice Society of America, Justice League International, and Justice League, and one of the foremost sorcerers in the DC Universe, Nelson's most reoccurring conflict is his gradual loss of personal agency to Nabu and its effects on his relationships with others, including his love interest Inza Nelson.

Shazam (/ʃəˈzæm/), also known as The Captain and formerly known as Captain Marvel, is a superhero in American comic books originally published by Fawcett Comics and currently published by DC Comics. Artist C. C. Beck and writer Bill Parker created the character in 1939. Shazam first appeared in Whiz Comics #2 (cover-dated Feb. 1940), published by Fawcett Comics. Shazam is the alter-ego of William Joseph "Billy" Batson, a young boy who is granted magical powers by the Wizard by speaking the magic word "SHAZAM!", an acronym of six "immortal elders": Solomon, Hercules, Atlas, Zeus, Achilles, and Mercury, and transforms into a costumed adult superhero with various superpowers derived from specific attributes of the aforementioned elders.

The character battles evil in the form of an extensive rogues' gallery, most of them working in tandem as the Monster Society of Evil, including primary archenemies Black Adam, Doctor Sivana and Mister Mind. Billy often shares his powers with other children, primarily his sister Mary Batson and their best friend/foster brother Freddy Freeman, who also transform into superheroes and fight crime with Billy as members of the Marvel Family (also known as the Shazam Family or Shazamily). The character also serves as a notable member of several teams, including the Justice League and various other derivatives, Justice Society of America, and the Teen Titans.

Alan Ladd Wellington Scott is a superhero appearing in American comic books published by DC Comics, and the first character to bear the name Green Lantern. He fights evil with the aid of his mystical ring, which grants him a variety of powers. He was created by Martin Nodell and Bill Finger, first appearing in the comic book All-American Comics #16, published on July 10, 1940.

Alan Scott was created after Nodell became inspired by the characters from Greek, Norse, and Middle Eastern myths and tales, including Aladdin from One Thousand and One Nights, and sought to create a popular entertainment character who fought evil with the aid of a magic ring that grants him various supernatural powers. After debuting in All-American Comics, Alan Scott soon became popular enough to sustain his own comic book, Green Lantern. Around this time DC also began experimenting with fictional crossovers between its characters, leading towards a shared universe of characters. As one of the publisher's most popular heroes, Alan became a founding member of the Justice Society of America, one of the first such teams of "mystery men" or superheroes in comic books.

The Justice League, or Justice League of America (JLA), is a group of superheroes appearing in American comic books published by DC Comics. The team first appeared in The Brave and the Bold #28 (March 1960). Writer Gardner Fox conceived the team as a revival of the Justice Society of America, a similar team from DC Comics from the 1940s which had been pulled out of print due to a decline in sales. The Justice League is an all-star ensemble cast of established superhero characters from DC Comics' portfolio. Diegetically, these superheroes usually operate independently but occasionally assemble as a team to tackle especially formidable villains. This is in contrast to certain other superhero teams such as the Doom Patrol or Marvel’s X-Men whose characters were created specifically to be part of the team, with the team being central to their identity. The cast of the Justice League usually features a few highly popular characters who have their own solo books, such as Superman, Batman, and Wonder Woman, alongside several lesser-known characters who benefit from exposure.

The Justice League was created to boost the profiles and sales of these characters through cross-promotion and helped develop the DC Universe as a shared universe, as it is through teams like the Justice League that the setting's characters regularly interact with each other.

The Flash is the name of several superheroes appearing in American comic books published by DC Comics. Created by writer Gardner Fox and artist Harry Lampert, the original Flash first appeared in Flash Comics #1 (cover-dated January 1940, released November 1939). Nicknamed "the Scarlet Speedster", all incarnations of the Flash possess "superspeed", which includes the ability to run, move, and think extremely fast, use superhuman reflexes, and seemingly violate certain laws of physics.

Thus far, at least five different characters –each of whom somehow gained the power of "the Speed Force"– have assumed the mantle of the Flash in DC's history: college athlete Jay Garrick (1940–1951, 1961–2011, 2017–present), forensic scientist Barry Allen (1956–1985, 2008–present), Barry's nephew Wally West (1986–2011, 2016–present), Barry's grandson Bart Allen (2006–2007), and Chinese-American Avery Ho (2017–present). Each incarnation of the Flash has been a key member of at least one of DC's premier teams: the Justice Society of America, the Justice League, and the Teen Titans.

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.
