- You may be looking for the Archie Comics' Sonic the Hedgehog's version of Silver's future, 3437 P.X.E..
In this future, Iblis had devastated the planet for two centuries after the "Iblis Trigger" released it at the time of Princess Elise's death because Sonic could not save her. Despite many attempts to destroy Iblis, Silver and Blaze were unable to and as such went back through time to kill the "Iblis Trigger". The future was presumably changed for the worse when Mephiles the Dark fused with Iblis to become Solaris. However, when Elise and Sonic went back through time to extinguish the flame that would become Solaris, the future was changed yet again.
Although the future had changed, it had not changed much. Instead of Iblis, the world had been destroyed by the Ifrit, who had been released by Eggman Nega. Silver once again headed back through time to change the future, and after confronting Eggman Nega in the Ifrit's dimension (which, according to Silver, greatly resembled his own future), the Ifrit and Eggman Nega were sealed away within that dimension, presumably altering the future for the better.
In the DS version of Sonic Colors, Silver returns to Sonic's time, stating that the future is much better than the present, meaning that the future had been saved.
Apperances in other media
In the Archie Sonic the Hedgehog comics, Silver's future also occurs two-hundred years into the future in the year 3437 P.X.E., this time in Mobius Prime's timeline. Due to the treachery of one of the Legendary Freedom Fighters, they were all destroyed and Silver's future was doomed without them. After several failed visits to the past to prevent this devastation from happening, Silver discovered his era's ruin was due to Mecha Sally's actions, but when he sat out to stop her, the Multiverse was forever changed by the Genesis Wave.
Following the events of Worlds Unite, Silver's future is virtually indistinguishable from the games. In addition to Silver, individuals like Professor Von Schlemmer and Gold the Tenrec inhabit this era as well.
- According to the English sites for Sonic the Hedgehog (2006), it is the norm in Silver's future for people to possess psychic powers, and the people of this time are described as being powerful and regularly moving objects using telekinesis. In the Sonic the Hedgehog: Official Game Guide however, psychic powers in Silver's future are described as a rare talent.
