The Experiment

It's a normal day in Möbius. Sonic and his friends are anticipating Eggman's next attack after he randomly disappeared. Let's just say that Eggman wanted to make Shadow, his acquaintance, stronger. The result he gets is unexpected and Shadow believes that he's more of a monster. Shadow goes to Sonic and his friends to get help but soon realizes that he will only causes harm. Shadow disappears after an incident and Sonic, Tails, Rouge, and Amy go out to find him but don't have a cure. What if that only cure is to turn him more into a monster?
