Hello... Do you want to play with me, soul from the other world? *does a creepy laugh*

*You were playing a normal Sonic game... Or atleast you thought you were and suddently a shock hits you making you uncouscious. You wake up in Green Hill but not quite in your own body. You were in a mobian body (you can choose any character or use your own oc). When you looked around you saw everything was messed up. There were dwd flickies and blood everywhere. The sky was a crimson red just lime the water. But you see a certain familiar blue hedgehog.... **but not the one you know and love***
