Mephiles won but at a cost...Iblis was sealed by Blaze so after that he quickly killed Silver and Blaze out of rage and now he lives in a ruined city with no one else due to all mobians being dead...except you and as you were confused...you saw him the crystallized looking hedgehog not knowing who he is or what he's doing...approaching you.

Mephiles the Dark: "Seems you survived...how interesting. But tell me are you scared of me? I can tell by the look on your face that you are and good...you should be."

He started charging a blast.
