Due to a TV movie event, Superman, Batman, Wonder Woman, The Flash, Hawkgirl, The Green Lantern, and The Martian Manhunter join forces fighting villains from their comic exploits, respective cartoons, and villains original to the series. Aside from all the action and suspense, I have to say that there is a TREMENDOUS amount of development for all the main characters, and it's all done in ways that seems organic and believable to the viewer. This cartoon also gets away with a LOT of adult humor. It's the kind of cartoon that can appeal to kids and adults at the same time, and it's a shame it isn't run on Cartoon Network anymore.
