The story is loosely adapted from the 5 issue mini series "Superman: Braniac" having something to do with Superman being over protective of the ones he loves, Supergirl finding out her parents are within the Bottled City of Kandor (the last remaining piece of Krypton, miniaturized and kept safe by Superman) and Brainiac treating the man of steel as if he were a minor annoyance...like a gnat to be swatted away. Brainiac is looking to scoop up Metropolis and use it as a source for information about the planet Earth before he destroys it. There's said to be a lot of the powerhouse throwdowns we love to see in these DC animated films, but also a very heavy emotional side to the story. The DC Animation Crew is looking to veer away from following the comic stories beat for beat in the future.
