Onyx City is a location that appears in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. It is a city that exist in Silver's future. It is a dystopian metropolis ruled over by the Onyx City Council and their Civil Protection Robots.


At some point, the people of Onyx City were apparently split into different work groups with various assigned colors and shifts. The people clearly disliked the order of their society but seemed unable or unwilling to oppose it, presumably because of the Onyx City Council's Civil Protection Robots and other technology.[1]


  • Onyx City's name is presumably derived from Onyx Island.
