Soumerca is a location that appears in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. It is a continent in the southern hemisphere of Mobius. It is mostly covered by a vast jungle area and contains many ancient settlements from the distant past.


The continent of Soumerca is the ancient home of the Felidae and the Wolf Pack, as well as the site of Ixis Vale's tomb.[1][2][3] Some time after the Forgotten War and 4,000 years before the First Robotnik War, it was visited by a group of Echidnas from Albion seeking a new home. This group ended up fighting with the Felidae, and split into three factions: the Knuckles Clan, Nocturnus Clan, and a group of intellectuals who left to escape the conflict, eventually traveling to Downunda and building Echidnaopolis. The Knuckles Clan were eventually wiped out by the vengeful Chaos, while the Nocturnus Clan disappeared as a result of the Argus Event. [4][5][6] At some point, a mystical stone known as the Ancient Onyx became a sacred artifact to both the Felidae and Wolves, and was also used by Tikal of the Knuckles Clan to imprison Chaos.[7][8] The Wolves eventually departed their homeland for lands in Northamer, and the Felidae laid claim to the entire region.[2]





  • Soumerca is based on South America, with the name being a partial portmanteau.
    • Coincidentally, in the comics' storyline, Soumerca may have been South America before the Xorda Attack on Earth.
  • Soumerca's name was introduced in an entry on the Sonic the Hedgehog comic blog detailing E-102 Gamma's mission to locate and "liberate" the remaining E-100 Series robots of the Eggman Empire.[9]
