When it comes to comic adaptations, the DC Animated Universe (DCAU) is pretty much the cream of the crop. Running for over a decade, the shared universe included Batman: the Animated Series, Superman: the Animated Series, Batman Beyond, Justice League, Justice League Unlimited, and various tie-in movies and comics. Each series was full of awesome moments.
A good number of the scenes below come from Justice League Unlimited, which is my favorite of the DCAU series, but that’s not intended as a slight to the other shows. Suffice it to say that most everything associated with the DCAU was awesome, and the shows generally got better as they went on.
