-> '''Superman:''' I once thought I could protect the world by myself, but I was wrong. Working together, we saved the planet, and I believe that if we stay together as a team, we could be a force that could truly work for the ideals of peace and justice.\\
'''The Flash:''' What, like a bunch of "WesternAnimation/SuperFriends"?\\
'''Superman:''' More like a...Justice League.

This animated {{adventure series}} is Creator/CartoonNetwork's update of ''WesternAnimation/SuperFriends'', with seven core heroes: {{Franchise/Superman}}, Franchise/WonderWoman, {{Franchise/Batman}}, Franchise/GreenLantern (John Stewart), Franchise/TheFlash (Wally West), [[ComicBook/{{Hawkman}} Hawkgirl]] and the MartianManhunter. Existing in [[{{Franchise/DCAU}} the same universe]] as ''WesternAnimation/BatmanTheAnimatedSeries'', ''WesternAnimation/SupermanTheAnimatedSeries'', ''WesternAnimation/StaticShock'' (post retcon), ''WesternAnimation/BatmanBeyond'', and ''WesternAnimation/TheZetaProject'', this show continued several story threads from those series and introduced new characters who had not previously appeared.

''[[http://www.youtube.com/watch?v=MXph0arElKs Justice League]]'' (Seasons One and Two)

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). A decision was made to not feature every member in every episode in order to allow for character focus; between two and five members would have an episode together 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.

''[[http://www.youtube.com/watch?v=wb5wZ7ZPXdA Justice League Unlimited]]'' (Seasons Three, Four and Five)

The successor series, ''Justice League Unlimited'', [[HeroesUnlimited added more heroes from DC Comics]], many of whom had never before been animated. Instead of the two or three part episodes, this series returned to the single episode format, which allowed for the more obscure heroes 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. This incarnation lasted 39 episodes.

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 Creator/JackKirby's [[ComicBook/NewGods Fourth World]] creations were used extensively in ''Superman: The Animated Series'', Creator/SteveDitko's creations got the same treatment in this incarnation.

To date, the series comprises the last installments of the [[Franchise/{{DCAU}} DC Animated Universe]].

For the comic this show was based on, see ''Franchise/JusticeLeagueOfAmerica''. See also ''WesternAnimation/JusticeLeagueCrisisOnTwoEarths'', A DirectToDVD movie which started off as a movie [[TheMovie bridging the gap]] between the end of ''Justice League'' and the beginning of ''Unlimited''. Though not set within the [=DCAU=], the film retains many of the plot points and themes of the original story.
