"How about the reader was so raged when her step dad killed her friend, that she became something similar to Dark Sonic and then killed her step dad. After that, she had to find the seven Chaos Emeralds to bring Shadow back to life"SugarKitty101
I agree with SugarKitty101 but here's the twist she meat Sonic and the others including Silver the Hedgehog. Then they have to go to the sprite realm to find out if shadow even wants to come back to life, while they're looking for him, he hears that they're in the sprite realm and he looks for them because he wants to live again. But Rouge the Bat says that Shadow loves her and hates (Y/N). They leave and go back home but (Y/N) is about to die because of her step dad and Shadow saves (Y/N) and kills her step dad. The Eggface (Eggman) kidnaps (Y/N) and Shadow is about to die again but then (Y/N) saves him this time... (you take it from there).
