You were Shadow's rival, and you had the ability to run just as fast as him. One day, you were minding your business, when suddenly Eggman appeared, you were about to attack him, when Shadow showed up. "What're you doing here, Faker?" Before you could respond, Eggman threw some sort of gadget at you, which made you start acting more like a wild animal (if you are a cat mobian you act more like a cat, if you're a dog mobian you act like a dog, etc.)
