the missing hero

this story is a side part of a au made by artist called snoophise, where the story is about a hyper form shadow constantly taking sonics good chaos energy and making sure he stays slient by making him dark sonic and in my story I am focusing on tails and the others as they slowy figure out and find sonic and shadow.
