The Flash: What, like a bunch of Super Friends?
Superman: More like a... Justice League.
The Flash: Do you have any idea how corny that sounds?
Justice League (also known as Justice League Unlimited) is an animated adventure series based on the Justice League of America, with seven core heroes: Superman, Batman, Wonder Woman, Green Lantern (John Stewart), The Flash (Wally West), Hawkgirl and the Martian Manhunter. Existing in the same universe as Batman: The Animated Series, Superman: The Animated Series, Static Shock (post-retcon), Batman Beyond, and The Zeta Project, this show continued several story threads from those series and introduced new characters who had not previously appeared.
Justice League (2001-2004)
Banding together for the first time to face powerful alien conquerors, Superman, Batman, Wonder Woman, The Flash, the Green Lantern (John Stewart), Hawkgirl, and the Martian Manhunter officially organize themselves as a team, anticipating having to deal with other threats that they cannot face alone. This incarnation lasted two seasons and 52 episodes (most of which were two-parters, with three three-parters and a single standalone episode). To avoid overcrowding that would come with featuring every member in every episode, between two and five members would be in the focal point of a story and the entire League appeared only a few times. Turning most stories into two or three part episodes allowed for a much larger scope that could not be accomplished in 22 minutes.
Justice League Unlimited (2004-2006)
The successor series, Justice League Unlimited, added more heroes from DC Comics, many of whom had never before been animated. After the events of the second season, the League recruit heroes from around the world to be prepared for the most powerful threats. Instead of the two or three part episodes, this series returned to the single episode format, which allowed for more obscure heroes and minor comic arcs to be spotlighted. To balance this out, a very strong myth arc was formed telling of a government conspiracy against the League, picking up from a few previous episodes, not just from the first Justice League series, but all the way back from Superman: The Animated Series. In addition, the villains get desperate as they have to face against a very powerful and well organized Justice League and eventually create the Legion of Doom in response. This incarnation lasted 39 episodes and was the last show overall in the DC Animated Universe.
Both iterations of Justice League were distinctive among superhero series for being true ensemble pieces. Pick any member of the core cast and in any given episode he or she might be the main hero of the story, used mainly as part of the larger team, or never even mentioned at all. Supporting cast members rotated out weekly, especially in Unlimited. In addition, while Jack Kirby's Fourth World creations were used extensively in Superman: The Animated Series, Steve Ditko's creations got the same treatment in this incarnation.
There have been a series of animated movies featuring the Justice League in the DC Universe Animated Original Movies series, separate from the DCAU, but frequently use the same voice actors from this show. These films include:
- Justice League: Crisis on Two Earths: Notable for having started off as a movie bridging the gap between the end of Justice League and the beginning of Unlimited. While no longer set within the DCAU, the film retains many of the plot points and themes of the series.
- Justice League: Doom: A loose adaptation of the "Tower of Babel" arc, almost all roles are reprised by the animated series actors. note
- Justice League: The New Frontier: A direct adaptation of the famed comic book DC: The New Frontier. Although it has a scope larger than just the League and more the general DC universe, it was renamed to include the Justice League in the title.
The DC Animated Movie Universe also contains films using the Justice League title, but are unrelated to the Justice League animated series and the DCAU. These films include:
- Justice League: The Flashpoint Paradox: An adaptation of Flashpoint, it's still a Flash-centric but the League (or lack thereof in the changed timeline) plays a central story.
- Justice League: War: An adaptation of the New 52 version of the origin of the Justice League, as they band together to face an invasion of Earth via Darkseid. Loosely a sequel to The Flashpoint Paradox.
- Justice League: Throne of Atlantis: A direct sequel to Justice League War. After previously leaving Aquaman out of the origin story, he shows up and joins the League to thwart a plot against the surface by Orm the Ocean Master.
- Justice League vs. Teen Titans: The two super hero teams come to blows concerning Raven and her connection to her demonic father Trigon.
The Injustice: Gods Among Us video game series also features the reprises of numerous charactersList , but also does not take place in the DCAU.
The series has finally received an official animated film continuation in the form of Justice League vs. The Fatal Five, which is part of the DCAU.
