The Justice League is an all-star ensemble cast of established superhero characters from DC Comics' portfolio.

After World War II, superheroes fell out of popularity, which led to the cancellation of many characters, including the Justice Society, which last appeared in All-Star Comics #57 (March 1951).

The initial Justice League lineup included seven of DC Comics' superheroes who were regularly published at that time: Superman, Batman, Aquaman, the Flash, Green Lantern, the Martian Manhunter, and Wonder Woman.

Fox also created a new, non-superhero character called Snapper Carr that was intended to represent DC's teenage readership and joined the League as an Honorary member in their debut story.

[5] While Superman and Batman were included in the Justice League's initial lineup, they were largely absent from the League's early stories, playing only minor roles as the pair were already starring together in DC's World's Finest Comics and Fox was worried the two more famous heroes would detract attention from their less popular teammates.

From the Justice League's inception in 1960 up until 1984, the team's roster always included a number of A-list characters to draw in readers, such as Wonder Woman and Superman.

The Justice League International was recognized by the United Nations as a political entity and established "embassies" all over the world.

This series utilized a "back-to-basics" approach by shifting the focus back on the team's original and most famous seven members (or their successors): Superman, Batman, Wonder Woman, Aquaman, the Flash (Wally West), Green Lantern (Kyle Rayner), and the Martian Manhunter.

[13] The Justice League books more or less continued the trend set by the JLA era: world-shaking threats with epic stakes, with a focus on plot over character development, and strong tie-ins to all the company's crossover events.

Continuing to deal with the concerns of the Source Wall being broken, Cyborg, Starfire, Green Lantern Jessica Cruz, and Azrael find themselves being lured by Darkseid into a newly inhabited area in outer space named the Ghost Sector.

[16][17] Being led by Wonder Woman, the team members include John Constantine, Zatanna, Swamp Thing, Man-Bat, Detective Chimp, Doctor Fate, and briefly Animal Man.

The fourth volume of the definitive Justice League title continues well into the Infinite Frontier era and reaches a conclusion with a total of 75 issues in June 2022.

The main team comprises Superman, Batman, Wonder Woman, Flash, Atom (Ryan Choi), Black Lightning, Star Sapphire, Green Lantern, and many others.

DC Comics has in several periods deviated from this formula, most notably in the late 1980s and early 1990s with books such as Justice League International, which deliberately featured a cast of lesser-known characters.

The advantage of this was that lesser-known characters are not burdened by convoluted continuities, which gave writers more creative flexibility to write character-driven stories.

Particularly in the early decades of publication, DC Comics was keen for its superheroes to be perceived as law-abiding because children were the main audience.

While sometimes the League is shown to have a designated chairperson or leader, there is otherwise no hierarchy; they are a small band of equals who make major decisions, such as inducting new members, by vote.

The Legion of Doom was created for the Challenge of the Superfriends animated TV series as a villainous counterpart to the Justice League.

In that original incarnation, it consisted of established villains associated with each of the Justice League's members; e.g., Lex Luthor for Superman, Joker for Batman, Sinestro for the Green Lantern, Black Manta for the Aquaman, Gorilla Grodd for the Flash, and the Cheetah for Wonder Woman.

[2] The original Justice League of America series won two 1961 Alley Awards in the categories "Best Comic Book" and "Best Adventure-Hero Group.

"[28] In 1963, the series won "Favorite Novel" ("Crisis on Earth-One/Crisis on Earth-Two" in Justice League of America #21–22 by Gardner Fox and Mike Sekowsky) and "Strip that Should Be Improved."

There also an award specific to the series, "Artist Preferred on Justice League of America," that was won by Murphy Anderson.

In the ride, guests board vehicles equipped with blasters as they join the Justice League in the fight against Starro, who has mind-controlled the citizens of Metropolis.
