Summary
“Rouge,” Shadow continued, “I want to know why you keep coming back here. Why you…stay with G.U.N. There must be some reason besides the money.” Shadow faced her with his watery reflection. “And I know that because…this place seems like somewhere you’d want to stay far, far away from.”
As Rouge blinked back at him, her mouth turned to a thin smile. Well, he’s got me there.
“Fine,” she said. She turned at last to face the sky alongside him, and leaned against the railing, just as she had before he’d shown up. “I’ll tell you what I’m doing here. But don’t expect me to sugarcoat it.”

When Shadow is offered a position at G.U.N., Rouge has mixed feelings. She takes a moment to reflect on her life and how she got to this point. -

Summary
"I want my brother back, Abraham."
"Your...Your brother- You mean Project Shadow!?"
--
Maria Robotnik has lived for fifty years on the planet she once looked down upon from the ARK. She's had a fulfilling life, the medication she takes making her condition less life threatening and more chronic. Still, she's now in her 60s and she's not getting any younger. There's still one thing she wants more than anything. Her little brother. The reason she's still alive to begin with has been locked away all this time. He needs the chance to live a life of his own.
And it's hard to expect life to remain simple even when she does get him out. The world keeps turning and her cousin is still determined to take over it. Just as she and Shadow start to settle into a new normal, they have to fight for the world, though they're not alone in the fight.
And Shadow? Shadow is quickly learning that even in the new "normal" everything is somehow weirder than his life on the ARK. Especially when encountering a certain blue hedgehog.

Summary
In A Dark Ablaze AU:
40 years ago: The ARK is raided, but Shadow is saved by his "father" Black Doom and "raised" to be a formidably warrior. They return to earth to seek their revenge on the ones who took Maria from Shadow, even though Shadow's memories of her are faint and dim. No matter, they'll conquer this planet like they've done to hundreds of others. Or, they would, if Shadow could just beat this snarky blue rat! What makes Sonic so strong and why does Shadow's body shiver with excitement every time they fight?Starting with Sonic Adventure 2 Battle as a guideline, the Ablaze AU ask what if Shadow was raised by Black Doom, but was a little less brooding and little more flirty?

Summary
Summer "Sunny" was just another kid in the foster system, going from one family to the next. But, stumbling upon a perfectly cut gemstone became the catalyst to a series of events that would both upend her life, but also grant her things she never thought she'd get to keep. She just has to survive an evil genius's villainous schemes.
Follows through events of Sonic Adventure, Sonic Adventure 2, a dash of Team Dark from Sonic Heroes, and some other references/inspiration from other Sonic media. The brain rot has a chokehold on me.
Updates on Sundays & Wednesdays
Adjusted rating due to lack of any real violence. There is fighting, but little that would be described as graphic.

Summary
Sonic whimpered, sobbing into Rouge’s shoulder as he felt himself being split apart. They were too much, too big, and he was falling apart at the seams, with only Shadow’s hands and Rouge’s kisses keeping him together.

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.

Summary
"S-Shadow?"
The ebony hedgehog narrowed his eyes at the look on the hedgehog’s face. It'd take him a billion years to decipher what those wide emerald eyes were thinking. "How do you know the name that I go by?"
Tears invaded Sonic's vision, never did they fall, even if he ignored every emotional wall he’d ever built, breaking through like a wrecking ball. Frozen in place, unsure whether to leap towards him or run away and attempt to bring coherence to the situation, a single tear rolled down his cheek. It was numb, he couldn’t feel the warmth of the salt his body produced. He didn’t know whether to be relieved or even more terrified at the sensation.__
Sonic expected there to be some troubles in this new adventure he found himself in. After all, someone was stealing his identity to destroy military bases. What he didn't expect though was to wake up in his clockless house... on the MOON.or
Sonic finds himself in a time loop, and the only way it breaks is if he convinces Shadow that he knows him (at least that's what he thinks).or, or
Sonic Adventure 2 with a strange, almost eerie change of events and then a rewrite of the July calendar. -

The being, calling itself Terios the Shadow, promises him great power and control and immediately gets to work stealing Chaos Emeralds and causing mayhem.
It doesn't take long before Terios runs into altercations with the one and only Sonic the Hedgehog. -

Summary
Things are finally settling down. Heyu, Humi and Iota are staying at Heyu's parents' place in Station Square while their home gets renovated, and things are going great! Everyone's getting along, and it's nice to be back in his hometown.
And yet, something's prickling at the back of his mind. Like he's waiting for the other shoe to drop.
It's probably nothing. It's not like Eggman is going to come out of nowhere with yet another giant space gun, right?

Summary
Miles "Tails" Prower had been having a pretty good start to the week.
So it was no surprise when it started spiraling into one of his worst after being caught out in a bit of rain. Option one would be ignoring it until he eventually felt better or, option two, at least giving a responsible adult the heads up that he was sick and home alone.In this case, Tails went with option one.
And that was a mistake, one Big Brother will make sure won't happen again.✧ ✧ ✧
None of the fics in this series are connected and can be read as standalones.

Summary
It was quiet. Too quiet.
Shadow came to a quick, abrupt stop, causing Sonic to crash into him with a half-assed attempt to come to a skidding stop. Sonic got a faceful of spines while Shadow was left with his dignity almost destroyed. He snarled, whipping around and facing his rival.
"Hedgehog, can't you stop quicker?" Shadow spat.
Sonic mumbled a quick apology, and then Shadow's ears perked up as he turned to investigate the noise he had just heard. He rushed through the town, locating the screams — the cries — for help.
Shadow swore as he noticed mobians in the destruction of the town, trapped under rubble and stuck in places they could not get out of.
~~~
Nobody expected the world would be pushed into this state; bleak and hopeless.
The Resistance has been formed, and Eggman's hold on the Earth has strengthened with a mysterious figure by his side; Shadow, Sonic, and their friends must figure out how to defeat Eggman and bring peace to the world again.
But things are far more difficult than they originally seemed.

“If you thought that was fast, just wait until I get these off.” Sonic held up his wrist and Shadow immediately recognized the inhibitor rings.

Summary
The ARK was falling. The world was ending. Shadow was dying.
Sonic couldn't save him, and the memory haunts him. He failed, and across the bond, he had felt the dark hedgehog's life leech out. But the world was saved, and so continues to spin on; Sonic, despite it all, persists, left in a limbo he can't even name. His friends rally around him and try to draw him back out to the unshakeable, sunny speedster they all know; but none of them were there, none of them felt the bond forged in pure Chaos energy-
But, what better to lift his mood than a festival? And Earth has a special one coming up- the Fire in the Sky Festival, held once every 50 years to celebrate the close approach passing of the Black Comet.

Gerald Robotnik sought to create the Ultimate Life Form. But what if that life form wasn’t Shadow the Hedgehog? What if it was someone else—someone faster, someone freer, someone who never lets the past weigh him down?
This is my take on a Sonic Adventure 2 Battle AU where Sonic is the ultimate life form! :)
