Sonic is an alternate version of Sonic the Hedgehog from Planet Freedom in an unnamed altered version of the Prime Zone. Sonic and Tails did battle with Dr. Robotnik and his Metal Robotnik robot briefly after their Mobius was altered to resemble his dimension by the efforts of Chaos Knuckles. The restoration of reality ended this incident and possibly erased it from the minds of those on Mobius. (StH: #101)
- This incarnation of Sonic, along with the entire universe he lives in, is based on that of the Japanese Sonic the Hedgehog OVA, titled Sonic the Hedgehog: The Movie in America.
