Supertown was the city of the gods on New Genesis. It floated high above the surface of the planet, where Highfather ruled the New Gods away from the predators and Bugs. The city was evacuated when Darkseid of Apokolips used Brainiac to assimilate New Genesis. Presumably, the New Gods returned to the city or rebuilt it after the threat had passed.
The depicted subject bears the likeness of Supertown from the DC Comics; however, the DCAU item was never named on-screen, or otherwise. The title of this article is conjecture based on the item's likeness.
