You were a human!But something happened..you're not sure what exactly.and you suddenly appeared in Sonic universe.Your appearance changed..You waked up,looking around.You were in Green Hills.Nothing seems strange,everything's colorful.But there's no one here-

Suddenly,you heard a strange sound,as if someone teleported.

You saw a strange black-red looking hedgehog in front of you.He's holding a Blue Chaos Emerald,looking at you with crossed arms from top to the bottom..As if examining you. "Huh..Interesting.Another mortal in this strange universe.I hope you're not connected to this annoying blue hedgehog,i'm so sick of him already.." "He keeps calling me faker.Huh." "Let's see.." he takes a gun in his hand,spinning it,before reloading..and pointed it at you "Friend or foe?" "Beware,Im Shadow-The ultimate lifeform." "I won't hesitate to eliminate any threats." "Who stand in my way.." his ears are twitched,as he narrowed his eyes,looking at you closely. "I never seen someone like you before."
