Justice League

The Justice League is a strike force comprised of the world's greatest superheroes. They serve as the stalwart protectors of life, dedicated to protecting the world as the first line of defense against terrestrial, extraterrestrial, inter-dimensional and supernatural threats.

Founded by Batman and Wonder Woman following the death of Superman by the hands of the Kryptonian monstrosity Doomsday, the Justice League was formed when the New God known as Steppenwolf invaded Earth with his army of Parademons.

Having lost the world's greatest protector a year prior, Bruce Wayne and Diana set off to round up a team of powerful metahumans and other superpowered beings, including Aquaman, the Flash, and Cyborg to confront the invaders and save Earth, in which they emerged victorious with the aid of a resurrected Superman.

General

 * The Justice League in the DC Extended Universe is the third live-action incarnation of the Justice League, after the versions seen in the failed 1997 TV pilot and Smallville.
 * In Zack Snyder's Justice League, they do indeed take the team name of "Justice League" for themselves, as evidenced by their destroyed headquarters shown in the Knightmare future. However, the theatrical version of the film never mentions the name, or any name for the team.
 * Unlike most versions of the Justice League, this roster is only made up of six members.
 * Ironically, the promotional art of Aquaman for Batman v Superman: Dawn of Justice read "Unite the Seven", leading fans to speculate there would be seven members. However, the promo art was referring to the Seven Kingdoms of Atlantis.
 * Superman, Wonder Woman, Aquaman, and Cyborg are the only members of the Justice League known to have any surviving parents. The Flash only lost his mother, but his father has been imprisoned since his childhood, and Batman's parents were murdered when he was 9. Aquaman is a notable exception, as both his parents turn out to be alive and well despite one of them being presumed dead for some time. Superman is also an odd exception, as he's lost both his biological parents, though he was adopted by the Kents.
 * This represents an ongoing trope with DC Comics, in that their character roster is largely comprised of orphaned heroes.
 * The correct members of the Justice League can be counted as the modern version of the original unity that was formed to fight Darkseid in the Invasion of Earth: Diana represents both the Amazons and the Old Gods, Bruce, Barry, John and Victor represent the different tribes of men, Arthur represents the Atlanteans, and Clark represents the aid from other worlds.
