The team received its own title called Justice League of America in October 1960, which ran until 1987. A second volume ran from 2006 to 2011, and the current series called Justice League has been in publication since October 2011. Since its inception, the Justice League has been featured in various DC Comics-related media and merchandise.

Various comic book series featuring the Justice League have remained generally popular with fans since inception and, in most incarnations, its roster includes DC's most popular characters. The Justice League concept has also been adapted into various other entertainment media, including the classic Saturday morning Super Friends animated series (1973–1986), an unproduced Justice League of America live-action series (for which the pilot film exists), the animated series Justice League (2001–2004) and Justice League Unlimited (2004–2006). A live-action film was in the works in 2008 before being shelved. On June 6, 2012, Warner Bros. announced a new live action Justice League film was in development with Will Beall hired as screenwriter. However, the project was scrapped again. After the success of the Superman reboot Man of Steel, a sequel titled Batman v Superman: Dawn of Justice. Zack Snyder will direct and Chris Terrio, who also wrote for Dawn of Justice, is eyed by Warner Bros. to pen the script for Justice League.
Having successfully reintroduced a number of DC Comics' (then known as National Periodical Publications) Golden Age superhero characters (Flash, Green Lantern, etc.) during the late 1950s, editor Julius Schwartz asked writer Gardner Fox to reintroduce the Justice Society of America. Schwartz, influenced by the popularity of Major League Baseball's National League and American League, decided to change the name of the team from Justice Society to Justice League. The Justice League of America debuted in The Brave and the Bold #28 (February–March 1960), and after two further appearances in that title, got their own series which quickly became one of the company's best-selling titles. Fox and artist Mike Sekowsky were the creative team for the title's first eight years. Sekowsky's last issue was #63 (June 1968) and Fox departed with #65 (September 1968). Schwartz was the new title's editor and oversaw it until 1979.

The initial Justice League lineup included seven of DC Comics' superheroes who were regularly published at that time: Superman, Batman, Aquaman, Flash, Green Lantern, Martian Manhunter, and Wonder Woman. Rarely featured in most of the stories, Superman and Batman did not even appear on the cover most of the time. Three of DC's other surviving or revived characters, Green Arrow, the Atom, and Hawkman were added to the roster over the next four years.
The title's early success was indirectly responsible for the creation of the Fantastic Four. In his autobiography Stan Lee relates how in 1961, during a round of golf, DC publisher Jack Liebowitz mentioned to Marvel-Timely owner Martin Goodman how well DC's new book (Justice League) was selling. Later that day Goodman, a publishing trend-follower aware of the JLA's strong sales, told Lee, his comics editor, to come up with a team of superheroes for Marvel. According to Lee in Origins of Marvel Comics:
Martin mentioned that he had noticed one of the titles published by National Comics seemed to be selling better than most. It was a book called The [sic] Justice League of America and it was composed of a team of superheroes. ... ' If the Justice League is selling ', spoke he, "why don't we put out a comic book that features a team of superheroes?"
Goodman directed his comics editor, Stan Lee, to create a comic-book series about a team of superheroes. Lee and Jack Kirby produced the Fantastic Four.
Other versions of the story suggest that it was Irwin Donenfeld, rather than Liebowitz, who bragged. However, film producer and comics historian Michael Uslan partly debunked the story in a letter published in Alter Ego #43 (December 2004), pp. 43–44:
Irwin said he never played golf with Goodman, so the story is untrue. I heard this story more than a couple of times while sitting in the lunchroom at DC's 909 Third Avenue and 75 Rockefeller Plaza office as Sol Harrison and [production chief] Jack Adler were schmoozing with some of us ... who worked for DC during our college summers.... [T]he way I heard the story from Sol was that Goodman was playing with one of the heads of Independent News, not DC Comics (though DC owned Independent News). ... As the distributor of DC Comics, this man certainly knew all the sales figures and was in the best position to tell this tidbit to Goodman. ... Of course, Goodman would want to be playing golf with this fellow and be in his good graces. ... Sol worked closely with Independent News' top management over the decades and would have gotten this story straight from the horse's mouth.
The Justice League operated from a secret cave outside of the small town of Happy Harbor, Rhode Island. A teenager named Lucas "Snapper" Carr tagged along on missions, becoming both the team's mascot and an official member. Snapper, noted for speaking in beatnik dialect and snapping his fingers, helped the group defeat the giant space starfish Starro the Conqueror in the team's first appearance.
The supervillain Doctor Light first battled the team in issue #12 (June 1962). Justice League of America #21 and #22 (August–September 1963) saw the first team-up of the Justice League and the Justice Society of America as well as the first use of the term "Crisis" in reference to a crossover between characters. The following year's team-up with the Justice Society introduced the threat of the Crime Syndicate of America of Earth-Three. The character Metamorpho was offered membership in the Justice League but declined. Following the departures of Gardner Fox and Mike Sekowsky, writer Denny O'Neil and artist Dick Dillin became the new creative team. Dillin would draw the title from issue #64 (August 1968) through #183 (October 1980).
O'Neil reshaped the Justice League's membership by removing Wonder Woman in issue #69 and the Martian Manhunter in issue #71. Following the JLA-JSA team-up in issues #73-74 and the death of her husband, the Black Canary decided to move to Earth-One to make a fresh start, where she joins the Justice League. The following issue saw the character develop the superpower known as her "canary cry". In issue #77 (December 1969), Snapper Carr is tricked into betraying the cave headquarters' secret location to the Joker, resulting in his resignation from the team.
Main article: Justice League Satellite
In need of a new secure headquarters, the Justice League moved into an orbiting satellite headquarters in Justice League of America #78 (February 1970).The Elongated Man, the Red Tornado, Hawkwoman, Zatanna, and Firestorm joined the team, and Wonder Woman returned during this period.
Len Wein wrote issues #100–114, in which he and Dillin re-introduced the Seven Soldiers of Victory in issues #100-102 and the Freedom Fighters in issues #107-108. In the fall of 1972, Wein and writers Gerry Conway and Steve Englehart crafted a metafiction an unofficial crossover spanning titles from both Marvel and DC. Each comic featured Englehart, Conway, and Wein, as well as Wein's first wife Glynis, interacting with Marvel or DC characters at the Rutland Halloween Parade in Rutland, Vermont.
Beginning in Amazing Adventures #16 (by Englehart with art by Bob Brown and Frank McLaughlin), the story continued in Justice League of America #103 (by Wein, Dillin and Dick Giordano), and concluded in Thor #207 (by Conway and penciler John Buscema). As Englehart explained in 2010, "It certainly seemed like a radical concept and we knew that we had to be subtle (laughs) and each story had to stand on its own, but we really worked it out. It's really worthwhile to read those stories back to back to back — it didn't matter to us that one was at DC and two were at Marvel — I think it was us being creative, thinking what would be really cool to do. Justice League of America #103 also featured the Justice League offering membership to the Phantom Stranger. Len Wein commented on the Phantom Stranger's relationship with the JLA in a 2012 interview stating that the character "only sort of joined. He was offered membership but vanished, as per usual, without actually accepting the offer. Over the years, other writers have just assumed [he] was a member, but in my world, he never really said yes." Libra, a supervillain created by Wein and Dillin in Justice League of America #111 (May–June 1974),would play a leading role in Grant Morrison's Final Crisis storyline in 2008.
Writers Cary Bates and Elliot S. Maggin wrote themselves into the 1975 JLA-JSA crossover in issues #123 and 124 with Bates becoming a supervillain.
Wonder Woman rejoined the team following a major two-year story arc, largely written by Martin Pasko. To prove her worthiness to rejoin the JLA, Wonder Woman voluntarily underwent twelve trials analogous to the labors of Hercules, each of which was monitored in secret by a member of the JLA. After the conclusion of the storyline in Wonder Woman #222, the character's return to the JLA occurred in a two-part story in Justice League of America #128-129 (March–April 1976).
Steve Englehart wrote the series beginning with issue #139 and provided another unofficial crossover with Marvel Comics in issue #142 by reworking his character Mantis into the DC Universe as a character named "Willow". Englehart left the title with issue #150. From issue #139 to #157 the issues were giant sized.
Writer Gerry Conway had a lengthy association with the title as well. His first JLA story appeared in issue #125 (December 1975) and he became the series' regular writer with issue #151 (February 1978). With a few exceptions, Conway would write the team's adventures until issue #255 (October 1986). Julius Schwartz, who had edited the title since the first issue, left the series with issue #165 (April 1979). The 1979 crossover with the Justice Society in issues #171 and 172 saw the death of the original Mister Terrific. After Dick Dillin's death, George Pérez, Don Heck, and Rich Buckler would rotate as artist on the title. The double-sized anniversary issue #200 (March 1982) was a "jam" featuring a story written by Conway, a framing sequence drawn by Pérez, and chapters drawn by Pat Broderick, Jim Aparo, Dick Giordano, Gil Kane, Carmine Infantino, Brian Bolland, and Joe Kubert. Bolland's chapter gave the artist his "first stab at drawing Batman." Pérez would leave the title with issue #200 to concentrate on The New Teen Titans although he would contribute covers to the JLA through issue #220 (November 1983). The 1982 team-up with the Justice Society in issues #207-209 crossed over with All-Star Squadron #14-15. A Justice League story by Gerry Conway and Rich Buckler originally intended for publication as an issue of All-New Collectors' Edition saw print in Justice League of America #210-212 (January 1983-March 1983).
Seeking to capitalize on the popularity of their other team books, which focused upon heroes in their late teens/early 20s, Gerry Conway and artist Chuck Patton revamped the Justice League series. After most of the original heroes fail to help fend off an invasion of Martians, Aquaman dissolves the League and rewrites its charter to allow only heroes who will devote their full time to the roster. The new team initially consists of Aquaman, Zatanna, Martian Manhunter, Elongated Man, the Vixen, and a trio of teenage heroes Gypsy, Steel, and Vibe. Aquaman leaves the team after a year, due to marital problems, and his role as leader is assumed by the Martian Manhunter.
The final storyline for the original Justice League of America series (#258-261), by writer J. M. DeMatteis and artist Luke McDonnell, concludes with the murders of Vibe and Steel by long-time League nemesis Professor Ivo, and the resignations of Vixen, Gypsy, and the Elongated Man during the events of DC's Legends miniseries, which sees the team disband.
Justice League International
Main articles: Justice League International and Justice League Europe
The 1986 company-wide crossover "Legends" concluded with the formation of a new Justice League. The new team was dubbed "Justice League" then "Justice League International" (JLI) and was given a mandate with less of an American focus. The new series, written by Keith Giffen and J. M. DeMatteis with art by Kevin Maguire (and later Adam Hughes), added quirky humor to the team's stories. In this incarnation, the membership consisted partly of heroes from Earths that, prior to their merging in the Crisis on Infinite Earths, were separate. The initial team included Batman, Black Canary, Blue Beetle, Captain Marvel, Doctor Light (a new Japanese female character, emerging from the Crisis of Infinite Earths, not the supervillain who had appeared previously), Doctor Fate, Martian Manhunter, Mister Miracle, and Guy Gardner; and soon after inception, adds Booster Gold, Captain Atom, Fire (then known as the Global Guardians' Green Flame), Ice (then known as the Global Guardians' Icemaiden), and two Rocket Reds (one was a Manhunter spy, and one was Dimitri Pushkin). The Giffen/DeMatteis team worked on Justice League for five years and closed out their run with the "Breakdowns" storyline in 1991 and 1992. The series' humorous tone and high level of characterization proved very popular.
After Giffen and DeMatteis' departure. DC created numerous spin-off titles. In 1996, the series was canceled, along with spinoffs Justice League Europe, Extreme Justice, and Justice League Task Force.

The low sales of the various Justice League spinoff books prompted DC to revamp the League as a single team (all the various branch teams were disbanded) on a single title. A Justice League of America formed in the September 1996 limited series Justice League: A Midsummer's Nightmare by Mark Waid and Fabian Nicieza, which reunited the "Original Seven" of the League for the first time since Crisis on Infinite Earths. In 1997, DC Comics launched a new Justice League series titled JLA, written by Grant Morrison with art by Howard Porter and inker John Dell.
Morrison introduced the idea of the JLA allegorically representing a pantheon of gods, with their different powers and personalities, incorporating such characters as Zauriel, Big Barda, Orion, Huntress, Oracle (Barbara Gordon), Steel (John Henry Irons), and Plastic Man. He also had Aztek, Tomorrow Woman, and Green Arrow (Connor Hawke) as temporaries.
During the 2005-2006 event "Infinite Crisis", the series ended as Green Arrow struggled in vain to keep the League afloat. (JLA #120-125)
Main article: 52 (comics)
In 52 Week 24, Firestorm recruits a group to reform the Justice League. It consists of Firehawk, Super-Chief, Bulleteer, and Ambush Bug. They fight a deranged Skeets who takes Super-Chief's powers, killing him and numerous people who had received powers through Lex Luthor's Everyman Project. Afterward, Firestorm breaks up the team. Also in the series, Luthor's new Infinity, Inc. was informally referred to as a "Justice League" in solicitations and on covers.

One year after the events of Infinite Crisis, Superman, Batman, and Wonder Woman reunite in the Batcave to re-form the League in Justice League of America #0, the kick-off for a new series by Brad Meltzer and Ed Benes. The series featured a roster which included Green Lantern (Hal Jordan), Black Canary, Red Arrow (Green Arrow's former sidekick), Red Tornado, Vixen, Black Lightning, and Hawkgirl. The first arc of the series focused upon Red Tornado and pitted the team against a new intelligent incarnation of Solomon Grundy and the rebuilt Amazo. The new incarnation of the team has two main headquarters, linked by a transporter. At the first site is The Hall, which in the mainstream DC Universe is a refurnished version of the Justice Society of America and the All-Star Squadron's former headquarters located in Washington, D.C.. Black Canary is elected as the first official Chairperson after the fight against Amazo and Solomon Grundy, and led both the Justice League and Justice Society in a complex quest to reunite time-lost members of the pre-Crisis Legion of Super-Heroes, who had been sent back in time to free both Bart Allen and Flash from the other dimensional realm of the Speed Force. Meltzer left the series at the end of issue #12, with one of his subplots (Per Degaton, a pre-nuclear fire mutation version of Despero, and a circa 1948 version of the Ultra-Humanite gathering for an unknown plot) resolved in the pages of Booster Gold.[volume & issue needed]
Dwayne McDuffie took over the writing job with the Justice League Anniversary Special and the main book with issue #13. Due to DC Comics seeking to launch a spin-off Justice League book led by Hal Jordan, the character was removed from the main League series and replaced by John Stewart. Firestorm also joined the roster, with the series entering into a series of tie-in storylines towards Countdown to Final Crisis, with the arrest of a large number of supervillains (gathered by Lex Luthor and Deathstroke to attack the League on the eve of the wedding of Black Canary and Green Arrow) setting up the Salvation Run tie-in miniseries. Also, roster members Red Tornado and Geo-Force were written out. McDuffie's removed Hal Jordan in favor of Stewart. Jordan was restored to the roster by issue #19 of the series, only to be removed once again by issue #31.
Issue #21 saw the return of Libra and the Human Flame, setting up their appearances in Final Crisis. Later issues would resolve issues involving Vixen's power level increase and see the integration of the Milestone Comics characters the Shadow Cabinet and Icon, who fought the Justice League over the remains of the villainous Doctor Light. The group suffered greater losses during Final Crisis with the deaths of Martian Manhunter and Batman, as well as the resignations of Superman and Wonder Woman, who could no longer devote themselves full-time to the League due to the events of the New Krypton and Rise of the Olympian storylines in their respective titles. Hal Jordan would resign as well, clearing the way for John Stewart's return to the team. Black Canary found herself declaring the League no more, though the group would continue with Canary taking a secondary role. Her last act as leader was to assign John Stewart and Firestorm the task of hunting down the Human Flame,[volume & issue needed] for his part in the murder of Martian Manhunter, as seen in the Final Crisis Aftermath: Run! miniseries.
Vixen would take over the team, with Plastic Man rejoining the group. Len Wein wrote a three-part fill-in story for Justice League of America that ran from #35 to #37. McDuffie was fired from the title before he could return, after discussion postings to the DC Comics message board, detailing behind-the-scenes creative decisions on his run, which were republished in the rumor column "Lying In The Gutter". James Robinson was announced as the new Justice League of America writer.
Wein's fill-in run would be published as Justice League: Cry For Justice neared its conclusion, as Vixen and Black Canary's group (sans John Stewart) would confront Hal Jordan and Green Arrow's makeshift Justice League group, which had stumbled upon a plot by the villain Prometheus that had resulted in much death and carnage. During the confrontation over Jordan's group using torture to extract information from the villains being blackmailed into carrying out Prometheus' plan, both Roy Harper and Supergirl would discover that one of Jordan's heroes, Captain Marvel Jr., was really Prometheus in disguise. In the ensuing battle, the League would suffer horrible losses: Roy Harper was maimed and his daughter Lian and hundreds of thousands of people in Star City would be killed by a doomsday device a Prometheus had activated. Vixen would have her leg broken and Plastic Man would have his powers permanently scrambled, making him a slowly disintegrating puddle creature. To save other cities from being destroyed like Star City, the League reluctantly allowed Prometheus to go free. Green Arrow (with help from the Shade) would later track down and kill Prometheus.[volume & issue needed]
Following the events of "Blackest Night", Hal Jordan and Donna Troy begin the task of rebuilding the League, with Green Arrow, the Atom, Batman, Mon-El, Donna, Cyborg, Doctor Light, Starfire, Congorilla, and the Guardian.[volume & issue needed]
At the end of issue #43, the majority of the new members leave. Mon-El and the Guardian leave after Mon-El returns to the future, Black Canary returns to the Birds of Prey, Starfire leaves to join the R.E.B.E.L.S., Green Lantern leaves to locate the other Lantern Corps Entities, and Green Arrow is forced to leave due to his fugitive status. James Robinson said this was due to having second thoughts about his decision to use so many characters, and that the team would have a different roster in the coming months. To replace the departed members, Jade and Jesse Quick were added to the team. Cyborg remained with the team in a reduced capacity, and was eventually given his own co-feature storyline for issues #48–50.
DC announced that Saint Walker of the Blue Lantern Corps would be joining the Justice League during a tie-in to the Reign of Doomsday crossover, but the character did not become a full member due to the cancellation of the title.
The series ended with issue #60 (October 2011), the title being one of the numerous DC books cancelled after the "Flashpoint" crossover. The finale issue was set one year after the events of #59 and saw Batman disbanding the League due to most of the individual members becoming preoccupied with personal commitments. The final storyline recounted the League's activities during the year-long gap, summarizing story arcs that had been planned for upcoming JLA issues but abandoned due to the transition to the New 52 continuity.

In September 2011, following the conclusion of the Flashpoint miniseries, all DC titles were canceled and relaunched, starting as issue #1 and DC's continuity was rebooted. Justice League of America was relaunched as Justice League, written by Geoff Johns and drawn by Jim Lee, and was the first of the new titles released, coming out the same day as the final issue of Flashpoint. The first six-issue storyline is set five years in the past and features a new origin for the team. The series then shifted to the present in issue #7. After the first 12 issues, Jim Lee was succeeded as artist by Ivan Reis. Subsequently, Jason Fabok succeeded Reis as the book's regular penciller.
The initial roster of the team consists of Superman, Batman, Wonder Woman, Green Lantern (Hal Jordan; who has since left the team), Aquaman, the Flash (Barry Allen), and Cyborg, while the Atom (Rhonda Pineda), Firestorm (Ronnie Raymond), and Element Woman join as additional members.
In addition to this series, two other Justice League-related titles were launched during the same month: a new Justice League International; written by Dan Jurgens and drawn by Aaron Lopresti; featuring an initial roster of Batman, Booster Gold, Rocket Red (Gavril Ivanovich), Vixen, Green Lantern (Guy Gardner), Fire, Ice, August General in Iron, and Godiva, and Justice League Dark; written by Peter Milligan and drawn by Mikel Janin; featuring an initial roster consisting of John Constantine, Shade, the Changing Man, Madame Xanadu, Deadman, Zatanna, and new character called Mindwarp. In May 2012, DC announced the cancellation of Justice League International with issue 12 and an annual.

The cancellation of Justice League International led into the launch of a new Justice League of America title (volume 3). The new Justice League of America is entirely separate from the main Justice League as the new team was formed by Amanda Waller and consists of Steve Trevor, Martian Manhunter, Green Arrow, Hawkman, Catwoman, the new Green Lantern Simon Baz, Stargirl, Katana and Vibe. Katana and Vibe later received their own ongoing titles, although both were cancelled after 10 issues. The new Atom, Rhonda Pineda, is also a member of the Justice League of America. She works as a spy to gain intel on the Justice League, reporting to Amanda Waller and Steve Trevor. It is later revealed that, unknown to the members of either team, she is actually a member of Earth-3's Crime Syndicate, and is betraying both teams. Each member of the Justice League of America is intended to be a counterpart to the members of the Justice League, in case the Justice League would ever go rogue. Catwoman and Green Arrow both serve as counterparts for Batman.
The Justice League, Justice League of America and Justice League Dark clash in the "Trinity War" storyline; Atom is later revealed to be from a parallel universe; she is in fact a mole on both teams, and a member of the evil Crime Syndicate of Earth-Three. The Syndicate roundly defeats the assembled Leagues, triggering the Forever Evil crossover event. In the aftermath of Forever Evil, following their crucial and public role in defeating the Crime Syndicate, Lex Luthor and Captain Cold join the Justice League.
Main article: Justice League United
In August 2013, it was announced that Justice League of America would be retitled Justice League Canada following Forever Evil, with the team relocating to Canada. Adam Strange and a brand new character of Canadian origin will join the team. In December 2013, Jeff Lemire, the writer of the new Justice League Canada series, announced that Animal Man would be a part of the team. It was announced in January 2014 that the series would no longer be retitled, instead relaunching as Justice League United. The series, written by Lemire and drawn by Mike McKone, will feature a team consisting of Animal Man, Martian Manhunter, Green Arrow, Hawkman, Stargirl, Supergirl, Adam Strange, Alanna Strange, and an all new, super-powered Cree teenager. The new character is Equinox, a 16-year-old from Moose Factory with the civilian name Miiyahbin. Her powers stem from the Earth and change with the seasons.
Various origins of the Justice League
In a story told in flashback in Justice League of America #9 (February 1962), the Appelaxians infiltrated Earth. Competing alien warriors were sent to see who could conquer Earth first, to determine who will become the new ruler of their home planet. The aliens' attacks drew the attentions of Superman, Batman, Wonder Woman, Flash (Barry Allen), Green Lantern (Hal Jordan), Aquaman, and Martian Manhunter. While the superheroes individually defeated most of the invaders, the heroes fell prey to a single competitor's attack; only by working together were they able to defeat the competitor. For many years, the heroes heralded this adventure as the event that prompted them to agree to pool resources when confronted with similar menaces.
In Justice League of America #144 (July 1977), Green Arrow uncovered inconsistencies in the team's records and extracted admissions from his colleagues that the seven founders had actually formed the League after Martian Manhunter was rescued from Martian forces by the other six founders, along with several other heroes including Robin, Robotman, Congo Bill/Congorilla, Rex the Wonder Dog and even Lois Lane.
Green Lantern participated in this first adventure solely as Hal Jordan, as he had yet to become the costumed hero, the biggest inconsistency Arrow found, as they celebrated the earlier incident's date, while recounting only the later one's events. When the group formalized their agreement, they suppressed news of it because of anti-Martian hysteria. Because the heroes had not revealed their identities to each other at the time, they did not realize that Jordan and Green Lantern were one and the same when he turned up in costume during the event described in #9. While most subsequent accounts of the League have made little mention of this first adventure, the animated Justice League series adapted this tale as the origin of the Justice League as well.
Secret Origins (vol. 2) #32 (November 1988) updated Justice League of America #9's origin for post-Crisis continuity. Differences included the inclusion of the Silver Age Black Canary as a founding member and the absence of Batman, Wonder Woman and Superman. The JLA: Year One limited series, by Mark Waid, Brian Augustyn and Barry Kitson, further expanded the Secret Origins depiction.
In Justice League Task Force #16 (Sept. 1994), during Zero Hour, a then unknown superhuman named Triumph appeared. Triumph was revealed to have been a founding member of the Justice League and was their leader. On his first mission with the Justice League, Triumph seemingly "saved the world" but was teleported into a dimensional limbo that also affected the timestream, erasing all memory of him.
In Infinite Crisis #7 (June 2006), the formation of "New Earth" (the new name for the post-Crisis Earth) restored Wonder Woman as a founding member of the Justice League. In Brad Meltzer's Justice League of America (vol. 2) #0 (September 2006), it was revealed that Superman and Batman were again founding members as well. 52 #51 (June 2007) confirmed that the 1989 Secret Origins and JLA: Year One origins were still in continuity at that time, with Superman, Batman and Wonder Woman joining the team with founding members' status shortly after the group's formation with Aquaman, Black Canary, Flash, Green Lantern and Martian Manhunter. In Justice League of America #12 (October 2007), the founding members of the Justice League were shown to be Superman, Batman, Wonder Woman, Green Lantern (Hal Jordan), Flash (Barry Allen), Aquaman and the Martian Manhunter.
With DC's history rewritten due to the Flashpoint limited series, an entirely new origin for the Justice League appeared in the subsequent Justice League series which debuted with an October 2011 cover date as part of the company-wide event, The New 52. Issue #1 portrayed the first meeting between Batman and Hal Jordan, with the two encountering each other during a battle against a Parademon in Gotham City. After realizing the creature is extraterrestrial in origin, the two heroes head to Metropolis to seek out Superman only to be attacked by him. Later, after a brief fight in which the Flash arrives and Batman convinces Superman they are on the same side, they move to an abandoned building to work on analyzing a mysterious alien box, when it suddenly activates and more Parademons arrive. While fighting the Parademons, Aquaman and Wonder Woman appear and join forces with the other heroes. The mysterious box leads to Darkseid's arrival on Earth, and the heroes come together, along with the newcomer Cyborg, to defeat him. The public becomes enamored with the heroes, and a writer dubs the group the 'Justice League', following the Flash's suggestion of 'Super Seven'.
