Nekronopolis is a location that appears in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. It is a city on Angel Island and the Dark Mobius counterpart of Nekronopolis.
Once a glorious capital, Nekronopolis eventually reached a stage where it showed few signs of life; the streets were littered with flickering lampposts, overturned cars, fires, crumbling buildings and cracked pavement. Its most notable feature is the massively towering statue of Enerjak.
Nekronopolis was once the capital of the Dark Legion's nation, until it entered decline. The remaining Freedom Fighters hid within the sewers beneath the city. The city served as a battleground as Enerjak and his Prelates engaged the Freedom Fighters and their ally, Silver the Hedgehog, resulting in Enerjak's eventual defeat.
