Summary
During the events of Sonic Frontiers, Sonic isn't able to make it out of Cyberspace. The Chaos Emeralds collect on the Starfall Islands, left silent and untouched. Called forth by their sense of danger emanating from these circumstances, Chaos, the so-called God of Destruction, takes it upon themselves to figure out why the Chaos Emeralds were drawn to the Starfall Islands and why Sonic and his friends ended up there in the first place.
Unbeknownst to them, the islands was where Chaos' ancestors landed when they arrived on Earth, and as the Chao god discovers the secrets of their ancestors, they must tear themselves out of the guilt of their past actions and march forward to defend the planet they had once tried to destroy.

Summary
Oh to trek through the icy cold mountains with wind that blows from the seas, the sharp tang of the sea will grow closer, and the sea carries the rust, the decay, the death, of the island just across the shore. On that island is the dead remains of Eggmanland, dilapidated and shattered, left to rot among dry, salty soil. But within the ruins is a sewer system that leads to the pipes, and through those pipes is a temple, hidden from civilization for ages and ages since its building.
And in front of that temple?
A pit.
Welcome to 2,889 KM, an AU that takes place some time after the events of Sonic Unleashed where Eggmanland has been left to rot for years. We follow Mighty and Ray as they track down Fang, who they witnessed near-fatally wound a passerby. Fang leads them to the ruins of Eggmanland, where they track him all the way down to the pit that stretches all the way down to Earth's outer core. The pit's seal is opened, and the trio finds Eggmanland to burst with life once again, the screams of the earth twins fueling it. They fight for their lives against the terrors of the twins who are not sleeping, but aren't quite awake either.

Summary
Things slow down for the heroes during the events of Sonic Unleashed as they take a break from globe-trotting to celebrate Chip's first Christmas. A Christmas special I wanted to write because it would be cute and also I got really emotional thinking about how much Chip would've loved to celebrate Christmas.

Summary
Sonic pretty much always wins no matter what. This newest adventure was no different. All he needed to do was grab the Chaos Emeralds and beat that nasty Eggman!!
However, something seems...wrong. It's almost as if Eggman wants him to collect the emeralds and turn into Super Sonic. Paired with intel from Tails within Eggman's files that doesn't make sense, Sonic has a feeling that things aren't as they seem...but Sonic always wins!

Summary
A fantasy AU of Sonic Unleashed where the bond between two brothers can either save or doom the world of magic as they know it.
-
One night, Sonic blacks out and comes to with blood on his claws and the taste of copper on his lips. Tails lies there, too still, and in a moment of panic, Sonic runs into the woods afraid he's done the worst thing imaginable.
But Tails isn't dead.
His body is marred by the scars of that night and his leg now requires a permanent brace, but he's determined to find his brother again. Tails ends up working with the New Diamond Cutters, an experienced group sent from Clean Hunting & Co to track down the new lycanthrope threat. Meanwhile, Sonic has made friends with a lost, amnesiac fae named Chip. Together, the two journey through the forest in search of answers on Chips lost memories and perhaps a way for Sonic to learn how to control his werehog form.

Summary
I never thought I’d find myself in Crisis City again.
Never before was she in Crisis City. Never before had she even heard of Crisis City. And yet, standing in the blinding white space, unable to find the horizon, a bone-deep knowledge etched itself onto her tongue. Facing Sonic, with a towering (but no less bright) structure behind her, she…
or memories Blaze does not possess seem all too familiar.

Summary
Sonic defeated The End. They watched him pierce through the husk of Supreme and the threat in the sky, all in a second, colored cyan and shooting into the night like a star. First came joy. They waited for him to return to them, Emeralds in hand. Then came worry.
He never came down.
Across dimensions, the Ancients were victorious. The Pilots vanquished The End, and got to return to their home, alive, after fighting the greatest battle their people had ever witnessed. That, however, is all cut short when a boy comes falling from the sky, wrenching the Emeralds from their systems and sending the Islands into chaos. The Emeralds answer to him like they have never answered their machines. He speaks of having defeated The End.
A child from another dimension.
Sonic is stuck here. They promised him a way to return home if he can simply wait for them to build it. And in the meantime, they show him what life was like for the civilization that has long since passed. It seems like nothing more than a peaceful hiccup before he can get back to his friends.
But something is lurking in the shadows. Something sinister. Maybe this won't be a simple pit stop.

Summary
Sonic the Hedgehog.
He goes by many names, takes on many roles. To those closest to him, he’s the best friend you could ask for. To those who challenge him, he’s a force to be reckoned with. To most of the world, he’s a hero, a legend to rival the days of old.
If you were to ask Sonic himself, he would say he’s no one special.
He’s wrong.
He knows he’s wrong. He knows he’s special in ways he doesn’t yet understand. It’s hard to ignore when the chaos emeralds thrum constantly in the back of his head, reminding him of the role he’s meant to fill. The role he rejects every time he borrows their power.
When the time comes, he will accept, because that’s just who he is. For now, he tries to live life like he always has, because there comes a day when he will no longer be able to ignore what lies ahead of him.
Tell him, how does he make the most of the moment when the moment lasts eternity?(AKA: The chaos emeralds claim Sonic as their guardian, essentially turning him into a god. Now, he has to deal with the implications of that— and immortality.)
