Starting with the critically aclaimed Batman: The Animated Series, the DC Animated Universe (DCAU) is what made many of us fall in love with DC’s characters.
e have several DC animated universes. This timeline doesn’t cover all of them. But there is one that stands out above the rest. We present the DC Animated Universe, consisting of the Batman/Superman animated series, Justice League, Justice League Unlimited, Batman Beyond, etc. There were tie-in comics to these series that, as of right now, we do not include in the timeline. These tie-in comics are complex, and don’t always line up perfectly with the continuity of the shows they are based on. However, we will hopefully include them in future updates.
The official Animated DC Universe ends with "The Zeta Project", but "Teen Titans" taking place after it is a decent continuity.
The four following "Batman" movies are a build-up to the "75th Batman Anniversary" movie with the same characters and voice actors of previous "Batmen" but are all stand-alone.
"Young Justice" would most likely take place prior to or during "Justice League [Unlimited]" as the story revolves around 'sidekicks' just as superheroes are becoming popular but inputting it in there in the already existing Animated DC Universe would break-up the timeline. Additionally, it takes place on a different earth in a different timeline/universe, so it can be thought of as a stand-alone. The same can be said of "Justice League Action" as it's a remake of "Justice League". "JLA: Trapped In Time", I'm assuming, would take place as a stand-alone or after "Justice League Action".
The following 22 movies/shorts/series are all stand-alone and sprinkled in to build on the lore of previous characters and their team-ups.
Finally, "Justice League: The Flashpoint Paradox" marks the end of the previous Animated DC
Universe jump-starting the canon DCAU based on "The New 52". Saving these for last would make a good conclusion to the stories and lore of the previous movies' characters and "Justice Leagues", and even to all the stand-alones, to start anew in the DC Animated Universe.
Lastly, I threw in "Ben 10" just for fun.
The DC animated universe (DCAU; also referred to as the Timmverse by fans) is the shared universe centered on a group of animated television series based on DC Comics, produced by Warner Bros. Animation from the early 1990s to mid-2000s; beginning with Batman: The Animated Series in 1992, temporarily ending with Justice League Unlimited in 2006 and returning with Batman and Harley Quinn in 2017.
