But, an army of Metal Sonics created by Eggman follow her to this alternate timeline as well. To save her world, Amy must get help from Sonic, Tails, and Knuckles to track down the six other time stones, that way they can reverse time and restore her world to its original state. Along the way, Sonic and Amy learn that they have a lot more in common than they would expect to believe. But, things will get a lot more complicated when Metal Sonic and his army take over Green Hills. With help from new friends and old friends, Sonic will have to battle it out with Metal Sonic to save the world from a bad future. After all, there can only be one Sonic.
