Summary
When Shadow was about to fall to Earth after saving it from the ARK, Sonic grabbed his hand and switched their places at the last minute. Now, Shadow is left with grief and confusing feelings he never asked for. In the aftermath, he's made it his mission to watch over Tails, whose own grief and dangerous mental spiral are all too familiar. But when G.U.N. declares them a threat and Eggman releases a mysterious new weapon that seems to mock their past upon the world, survival will mean more than just fighting: It will mean confronting the pain that threatens to destroy them from within.

Summary
⚠️Content Warning for suicidal ideation and attempt⚠️
In one day, everything changed. Shadow blinked and everything he knew was gone or replaced. He now had to answer the question of what was left to do.
Just when he thought he was done staying in the past, that Time Eater just had to give him the irrational thing he had spent so much time foolishly hoping would happen. Only to rip it away once again.
Now in the same pit he was in back when he was first reawakened, Shadow, chasing an elusive "purpose," makes a hasty deal with GUN and gets more than he bargained for.

Summary
Amidst the separation, there are some things that'll prompt oneself to remember bittersweet memories of the other. Their argument, their laughter, their bond.

Summary
She's spent forty years fleeing her cousin. Only now does she dare look over her shoulder.
Once upon a time, Maria Robotnik wanted for nothing... So she thought. Ivo's tantrums seemed a small price to pay for her cushy life in Grandfather's manor on Earth, cured of her illness and the ARK signed over to the government in exchange for their silence. What did a young boy's childish insults matter, as long as the family was together?
As Gerald was often fond of telling the budding genius: a broken toy is nothing worth pitching a fit over.
Perhaps it's fate, then, that the Eclipse Cannon requires two sets of fingerprints to fire.
Be his friend, Grandfather told her. A cruel promise she cannot keep.

Summary
A figure slowly arising from the depths with a confident smile, crossing their arms and opening their mouth to speak. Their voice was slightly rough, almost as if they hadn’t used it in years. ‘’I’m the world’s ultimate lifeform, since you were so kind to release me, my master…’’ They began, making Sonic’s head snap right towards them. ‘’I will grant you-’’ Suddenly, the figure seemed to falter. And Sonic finally got a good look at them. Their fur was pitch black, quills slightly raised in a shape that resembled that of a star with red highlights adorning the edges. Rings clutching tightly onto their wrist. Sonic remained silent, hesitating for a few seconds before a nervous smile made its way into his face. ‘’Uh…’’ The figure cut him off. ‘’Why do you look like me?!’'
Or
Due to wonders of fate, Sonic is the one that frees shadow instead of eggman in the beginning of sa2. Shenanigans ensue.

Summary
The Space Colony ARK was supposed to create the Ultimate Lifeform. They made three prototypes, out of three different DNA stabilizers. And when the ARK was attacked, all three were sent to the planet below. GUN only found one. But once he was released, intent to avenge the family he lost, finding the other survivors may become the only way to save the planet.
Sonic, meanwhile, woke up confused, scared, and having missed fifty years of progress. He doesn't know why a man who looks like the Professor is destroying the planet, or why everyone is telling him that Shadow can't be trusted. Shadow would never hurt anyone... right? And if he did, would Sonic be powerful enough to stop him? Would he be able to bring himself to do it?
ARK Hedgehogs AU: Sonic, Shadow and Amy were born and raised on the Space Colony ARK. They find themselves on a war-torn planet, with a very powerful Robotnik, a very angry fox and echidna, and a desperation to find each other again.
