In this universe, Amy's story in Sonic Adventure after being kidnapped by Eggman Amy is robotitized rather than simply locked away. She becomes Rusty Rose and serves Eggman, having no memory of her previous life with Sonic. Gamma also never changed heart and remains alive. Sonic Heroes is the game with the most changes with Metal Sonic, forcing Amy to be his assistant and fight the teams. Sonic is furious with Eggman but can't destroy Rusty Rose because if Rusty Rose powers off the real Amy will die. How Sonic will rescue Amy is up to interpretation.
