Future Sonic

The Sonic from the future.

Future Sonic is the Sonic from a bad future, which gets fixed in Sonic Generations 2: Past, Present, Future. He got the scar on his chest when he went into a battle in the future, and got his robotic leg by exploding after the war. Since then, he has been looking for a weakness in Eggman's defense system, and looking for the stone of time so he can go back in time and stop the war from ever happening.
