Demon Island, formerly known as the Sunken Island is the Moebius counterpart to Angel Island (formerly known as the Floating Island).


Unlike Angel Island, the Sunken Island is located underneath the surface of Moebius's oceans, and is home to the city of Atlantinopolis, though it is still protected by a version of Knuckles as well as his associates, the Orderix. The Sunken Island was threatened with destruction when Dr. Ivo Robotnik secretly travelled to Anti Mobius and began using the Sunken Island's Anarchy Beryls to power his latest weapon. His plot was ultimately foiled however and the shield protecting the island from the water was restored. (StH: #44; :CSE)

Roughly two years later, the Sunken Island was conquered by Scourge the Hedgehog during his takeover of the planet, after defeating Anti-Knuckles. (StH: #193)

The Sunken Island's status following Scourge's defeat is unknown, though it was presumably liberated.

Background Information[]

When asked about Anti-Chaos and the island, Ian Flynn gave the following scenario: Anti-Pachacamac and his tribe were peaceful, Anti-Tikal instigated the vicious Anti-Chaos' attack. The Anti-Knuckles Clan placated Anti-Chaos, who voluntarily sealed himself inside the Master Emerald's counterpart, alongside Anti-Tikal.[1]
