- You may be looking for Sonic from the Mobius Prime universe. For other versions, see Sonic (disambiguation).
Sonic the Hedgehog, in an alternate future reality, was the renowned hero of Mobius who met his end at the hands of his former friend Knuckles the Echidna, under the guise of the evil Enerjak. Stripped of his Core, his body hung as a trophy alongside other fallen heroes inside Enerjaks Citadel of Darkness.
According to Knuckles, Sonic was jealous of him for taking out their universe's version of Dr. Eggman easily when Sonic had been trying to for years, as well as Sonic just wishing that he was as powerful as Knuckles. (ASUB)
While the 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. (ASUB, SU: #28)
