Science can explain anyone on Mobius...but not Sonic. Just how long has Dr Eggman been in the hedgehog's life? And why is it that the one we think we know the best turns out to be the one we know nothing about?

After the accident, Danny's not sure if he's even alive anymore. But he still thinks he's alive, so he can't be dead. He can't be dead because he's alive. He can't be a ghost because he's human. I'm alive. I'm alive. I'm alive. [Cover art by @chintastic on tumblr!]

Metonic (Sonic x Metal Sonic) One-shot

Sonic wakes up after a fight with Dr. Eggman, but finds himself stuck in a world that mirrors his own. With even the lines between friend and foe blurred, Sonic must struggle his way through a new reality; one that begins to reject his very existence. *Revived from deletion*

Sonic is captured by Eggman with the help of Shadow, but once Eggman reveals his evil plans, Sonic's true past is revealed. Shadow is shocked to find out that not only was Sonic was created aboard the ARK as well, he was made specifically to be his brother.

Sonic will have to take the plunge if he wants to avert the disaster he's destined to bring onto the world. Too bad for him, his friends aren't making his goodbye any easier than it should be...which is already hard since he can't tell them about his past. But a hedgehog's gotta do what a hedgehog's gotta do to save everything he's ever cared about. (Dark, Sonic-centric)

Deeply grieved by a personal loss, Sonic's sanity is badly damaged and continues to decay. But the deranged Doctor Eggman is not through with the cobalt hero yet. Thus, when the mad scientist's machinations reach a new level of depravity, Sonic submits to a darkness that may end up consuming them both. Is there anyone who can save the hero from himself? *Third requested fic*
