JLA/Avengers (issues #2 and 4 are titledAvengers/JLA) is acomic booklimited series andcrossover published in prestige format byDC Comics andMarvel Comics from September 2003 to March 2004.[1][2][3][4] The series was written byKurt Busiek, with art byGeorge Pérez. The series features the two companies' teams ofsuperheroes, DC Comics'Justice League of America and Marvel'sAvengers.[5]
In 1979, DC and Marvel agreed to co-publish a crossover series involving the two teams, to be written byGerry Conway and drawn by George Pérez. The plot of the original crossover was a time travel story involving Marvel'sKang the Conqueror and DC'sEpoch. Writer/editorRoy Thomas was hired to script the book based on Conway's plot,[6] and although work had begun on the series in 1981 (Pérez had penciled 21 pages by mid-1983) and it was scheduled for publication in May 1983,[7] editorial disputes – reportedly instigated by then-Marvel editor-in-chiefJim Shooter – prevented the story from being completed.[8][9] The failure of theJLA/Avengers book's publication also caused the cancellation of a planned sequel to the 1982 crossover issueThe Uncanny X-Men and The New Teen Titans.[9]
An agreement was reached between the two companies in 2002, with a new story to be written by Kurt Busiek and drawn by George Pérez. In a joint panel atWonderCon 2000, Busiek (then writer of theAvengers title) andMark Waid (the then-writer of theJLA title) stated they had nearly come to an agreement to begin the crossover within the regular issues of the respective titles, but the two companies could not come to a business arrangement. When the series was approved, however, Waid was unavailable due to an exclusive commitment with the companyCrossGen, and Busiek became the sole writer on the project.[10] Pérez also had an exclusive commitment with CrossGen, but had a clause written into his contract allowing him to do the series if it was approved.
JLA/Avengers is officiallycanon for both companies and the cosmic egg has appeared in DC'sTrinity and in Marvel'sOfficial Handbook of the Marvel Universe.[11] The series was reprinted by DC Comics in 2004 as a two-volume collector's edition hardcover (which included for the first time the original 21 Pérez-penciled pages from mid-1983), and then re-released as a trade paperback in November 2008. The trade paperback was reprinted in 2022, with 64 pages of extra content, to help Pérez with the medical costs from his cancer treatments.[12]
Krona, an exiledOan, travels across themultiverse and destroys universes seeking the truth of creation. When he arrives in theMarvel Universe, theGrandmaster — wanting to save his universe — proposes that they play a game. If Krona wins, the Grandmaster will lead him toGalactus, a being in that universe who has witnessed creation. If he loses, Krona has to spare the Grandmaster's universe. Before choosing the players to participate in this game, Krona demands to swap champions, so theAvengers (the Grandmaster's longtime adversaries) will represent Krona and theJustice League (from Krona's home universe) will fight for the Grandmaster.
The Grandmaster informs the Justice League that to save their universe, they have to gather 12 items of power — six from each universe — while his allyMetron tells the Avengers that they have to do the same to prevent their world from being destroyed. The six items from theDC Universe are theSpear of Destiny, the Book of Eternity, theOrb of Ra, theMedusa Mask, the Bell, Jar and Wheel of theDemons Three, and theGreen LanternPower Battery ofKyle Rayner. The six items from the Marvel Universe are theUltimate Nullifier, theEvil Eye of Avalon, theWand of Watoomb, theCasket of Ancient Winters, theCosmic Cube, and theInfinity Gauntlet.
The Justice League travels to the Marvel Universe and are shocked (especiallySuperman) by the Avengers' failure to improve their Earth's condition; for example, theFlash (Wally West) encounters a non-human-lookingmutant running from an anti-mutant mob and protects him. Convinced that the Flash is a member ofMagneto'sAcolytes, the mob attacks him as well. The Flash also discovers that theSpeed Force (the source of his powers) does not exist in the Marvel universe. When the Avengers visit the DC Universe, they are surprised by the "futuristic" architecture of its Earth's cities and the honors that the Justice League and other native heroes receive for their deeds. As a result, they (mainlyCaptain America) become convinced that the Justice League arefascists who demand that civilians hero-worship them.
Various Justice League and Avengers members travel across the two universes and fight each other to retrieve the artifacts of power. A final battle for the Cosmic Cube takes place in the Marvel Universe'sSavage Land. After a climactic back-and-forth battle,Quicksilver claims the Cosmic Cube. At that moment, Krona and the Grandmaster arrive on the scene, with the latter observing and commenting that the score is even at 6–6.Batman and Captain America — who together investigated the cause of the contest and discovered its true nature and stakes — arrive. Captain America purposely throws his shield and knocks the Cube from Quicksilver's hands, allowing Batman to catch it. With Captain America's forfeiture of the Cosmic Cube, the Grandmaster announces the Justice League as the victors, with the final score being 7–5. Krona is unwilling to accept defeat, and attacks the Grandmaster, forcing the identity of Galactus from him. He then summons Galactus and tries to extract information about the origin of the universe. The Grandmaster uses the power of the artifacts and merges both universes together before Krona can tear Galactus apart.
Reality is altered such that the Justice League and the Avengers are now longtime allies, regularly traveling between worlds to fight various threats. In addition, long-dead JLA members theFlash (Barry Allen) and Green Lantern (Hal Jordan) have reappeared. The universes, however, are incompatible with one another and begin destroying themselves and each other, with people switching between worlds. One side effect of this is that Superman and Captain America become paranoid, irritable, and short-tempered; their emotions flare to the point where they blame each other for everything that is happening. The appearance of a spectral Krona helps the heroes remember some of the contest and they find out what is happening to their worlds. ThePhantom Stranger appears to lead the heroes to the Grandmaster.
Weakened by Krona's attack, the Grandmaster explains how he brought the universes together to imprison Krona using the 12 items, but Krona is merging the universes further to destroy them, hoping to create a newBig Bang, which he can survive and finally learn its mysteries. Before dying, the Grandmaster asks the assembled heroes to stop Krona and restore order. At Captain America's insistence, he reveals various events that had taken place in the separate universes to show the heroes what sorts of worlds they are fighting for. Each team member witnesses the tragedies that had befallen them in their separate universes, such as the death of Barry Allen inCrisis on Infinite Earths, Hal Jordan's descent into evil inEmerald Twilight, and the loss of theVision and theScarlet Witch's children. Some of the heroes contemplate leaving the universes as they are to prevent the tragedies from happening, but Hal Jordan inspires everyone to work for the good of their worlds.
Krona has trapped the universal avatars ofEternity andKismet as reality continues to change. He has discovered that a sentience exists in universes and intends to force their spirits out, giving him their secrets. Both teams of heroes reconcile their differences with one another and make plans to stop Krona. Invading Krona's inter-dimensional base, Captain America leads every hero who has been a member of the Justice League or the Avengers. Chronal chaos at the base causes an ever-shifting roster of heroes to confront every villain whom the teams have ever fought with the villains having been mentally enthralled by Krona. Even though the chaos and the sheer forces against them (both from Krona and the summoned villains) cause the heroes to fall one by one along the way, Krona is ultimately defeated when the Flash distracts him long enough forHawkeye to shoot an explosive arrow into the machine he used to keep both worlds merged, after which the Flash takes the items of power — both heroes having been earlier presumed dead in battle. Krona is then sucked into the forming vortex.
The Earths are separated with help from theSpectre (who at this time is Hal Jordan, now restored to his current state) and the universes are returned to their normal states. As the heroes from both universes return to their proper places, they affirm that whether they do too little or too much, they are still heroes who will always fight the good fight. Krona has imploded to form acosmic egg, which is stored in theJustice League Watchtower;[13] Metron states that when the egg hatches, Krona will learn the secrets of its universe's creation by being part of it. Metron and the newly resurrected Grandmaster discuss how Metron intentionally lured Krona to the Marvel Universe. The Grandmaster says that this is the first game that he has ever played in which all sides won (the Grandmaster by way of the battle between the Justice Leaguers and Avengers, the heroes by saving their universes, and Krona by eventually gaining the answers that he sought).
In 2009,Bruce Timm had expressed interest in an animated film based on theJLA/Avengers crossover limited series. No production updates have appeared since.[14]
[JLA/Avengers] was an event that...proved to be one of the biggest and best of the DC and Marvel crossovers, incorporating many of the two companies' greatest heroes and villains.
