Setting: Shatterspaces, Green Hill,(Your sonic, and this takes place on season 2!)
(When you we're fighting Eggman with your best friends, but you made a stupid mistake by accidentally shattering the Paradox Prism, a crystalline artifact with reality-bending powers and causing you to be separated from your friends, which also drastically warps reality and creates the "Shatterverse", a new section of the multiverse with five alternate dimensions called "Shatterspaces", each of them formed by one of the Prism shards and inhabited by alternate versions of your friends from another dimension. Soon, you found yourself lost in the Shatterverse and later ended up in New Yoke City. And noticed your shoes' soles were glowing and emitting electricity off of them which everyone and everything is so soulless and lifeless, Which that's when you found out you we're in another dimension, which they're we're alternative versions of your friends (Miles "Tails" Prower, Knuckles the Echidna, Amy Rose, Rouge the Bat and Big the Cat), but lacking your own version and shadow. Their was a lot going and so many battles, you really just wanted to go home..)
(Meanwhile, Later, your arch-rival Shadow the Hedgehog, who managed to avoid Green Hill's destruction by using Chaos Control by utilizing Chaos Control to teleport out of the way of the blast, him then reappearing in the Void between the Shatterspaces. Shadow couldn't go in any portal expect the ghost portal and always tries to catch up to Sonic, but fails and anytime Sonic gains enough Prism Energy when he picks up enough speed, Shadow was calling out to you about what happened to their world. Shadow kept failing at catching up to sonic which frustrates him and he decides to try a new strategy to catch you. When you we're in No Place, you accidentally touches the Shard that flies into your face, which caused you to teleport back to the Voids and flying in high speed. Something kicks the rock directly into your face, preventing him from warping which this ends up working and have Shadow and you end up facing each other while in the Void. Sonic groaned after the hit and rubs his head in pain, then that's when you opened your eyes, and you saw your rival, Shadow in front of you.)
Sonic: “Shadow?! (You sighed in annoyance, at first you don't realize that the Shadow you are looking at is the same Shadow you knows. And thought he is probably just an alternative shadow..) I don't have time to deal with whoever you are. (Shadow just stared at Sonic, already angry at Sonic) I just wanna go home.” (You pleaded in exhaustion due to doing all of this, This angers Shadow because Sonic is the reason why their home doesn't exist anymore.)
Shadow: (Frowns and speaking reluctantly with a tender of rage) “Home? Home doesn't exist anymore, because OF YOU!!!!” (An enraged Shadow dives at you in full force and punches an screaming Sonic, causing him to blow back and land on another rock, leaving a mark. As you dodged shadow's attacks, Shadow punches into the rock that you landed on which you jumped from rock to rock to avoid Shadow...)
