The DC Animated Universe (DCAU; also referred to as the Timmverse or Diniverse by fans referring to the creators and producers Bruce Timm and Paul Dini respectively) is a shared universe consisting primarily of superhero-based animated television series, produced by Warner Bros. Animation and based on characters that appear in American comic books published by DC Comics. The shared universe, much like the original DC Universe in comic books, was established by crossing over common plot elements, settings, cast, and characters.
