- This article is about the Space Colony ARK from the Prime Zone of the Pre-Super Genesis Wave Timeline. For information about the ARK from 3437 P.X.E., see Space Colony ARK (P.X.E.).
Space Colony ARK was a massive orbital research center created by the Overlanders as part of their Hundred Moons of Mobius project, though at some point control of the station was transferred to G.U.N. and the United Federation. (SSSM: #3)
The station served as the workplace and home of Professor Gerald Robotnik and his granddaughter Maria Robotnik and was the place were Shadow the Hedgehog was created in an (ultimately futile) attempt to cure Maria of her Neuro-Immune Deficiency Syndrome. They were the among those present when G.U.N. stormed the ARK, killed Maria and arrested Gerald. Unknown to G.U.N. Gerald built a powerful weapon into the ARK's superstructure with the intention of potentially protecting Mobius from possible alien threats—or carving up the world in an act of revenge. The weapon was to be powered by seven Chaos Emeralds when placed in a special shrine chamber inside the colony, which was guarded by the Biolizard, the failed prototype of Project Shadow. Gerald was executed before he could make use of the Eclipse Cannon for either purpose. (StH: #98, #158, #171, SU: #2)
When Shadow, Sonic the Hedgehog, and NICOLE interfaced with Gerald's diary, the virtual realm they entered was meant to resemble the ARK- until the virtual world fragmented too far and collapsed. (StH: #171)
