Sonic the Hedgehog (born day 162, 3220) is a character that appears in the Sonic the Hedgehog comic book series and its spin-offs published by Archie Comics. He was an alternate version of Sonic the Hedgehog from Dark Mobius. Once the renowned hero of Mobius, he met his end at the hands of his former friend Knuckles the Echidna, under the guise of the evil Enerjak.
Sonic's early history was most likely largely the same as his Mobius Prime counterpart's. The point at which things differed was when Knuckles became corrupted by his chaos powers and decided to conquer Mobius.
While the Dark Freedom Fighters were developing plans to defeat Knuckles, with Sally looking for the Sword of Acorns and making alliances, Sonic had another plan, which he discussed in a letter to her to let her know what was going on. Although he did not trust Mammoth Mogul, he believed that his old enemy also wanted to stop Knuckles, and so they formed an alliance. Amy and Tails already had leads on a couple of the Chaos Emeralds, and, with Mogul's help, they planned to get all seven together in a couple of weeks. They succeeded in obtaining the seven gems, and Sonic was able to become Super Sonic. In the end, Knuckles, now known as Enerjak, took the Chaos Emeralds so that his power would remain unrivaled, and he soundly crushed his opponents, including Super Sonic.
