Summary
When Eggman abandons Earth in search of a new world to conquer, he leaves behind a dangerous power vacuum—and chaos rushes in to fill it. As new and old enemies rise, Sonic faces an impossible choice: pursue his nemesis across the stars, or stay and defend a fracturing world in desperate need of its greatest hero.
But the deeper the conflict runs, the more Sonic and his allies begin to suspect a hidden hand is guiding their paths. A mysterious entity known only as the Realm Lord weaves a web of manipulation, ensnaring the fates of old friends like Amy and Tails, former rivals such as Knuckles and Metal Sonic, and even unlikely heroes like Cream the Rabbit.
Meanwhile, Shadow the Hedgehog launches a desperate journey through time and space, seeking the truth behind the being who spared him after the ARK Incident—and the dark secret it holds about his origin.As the Realm Lord’s designs come into focus, Sonic is pushed to the edge of his endurance, forced to confront enemies he can't outrun and choices he can't undo. To save the world, he may have to sacrifice the very thing that makes him who he is.

Various Sonic Oneshots by Crimson_Winter09

Summary
Various compiled Oneshots I write because I get cute small ideas that aren’t really big enough to turn into full fics but don’t fit into any of my full fics. This is kind of an AU I guess?? This contains two OCs of mine, one being fully my brainchild, the other being a more characterized version of my Sonic Forces avatar because “gee, I wanna self ship with Infinite, but I can’t use Andressa bc she’s dedicated to Shadow…ah! Sonic Forces avatar!”
Edit: Basically watch me drop piles of Espilver fluff and angst with occasional other ships.

These three things will spark a cataclysmic event that multiple realities would never see coming. In due time, Sonic and Shadow will realize that they're far more special than they ever imagined. They will also see just how crucial their relationship is to each other, and how far they're willing to go to prove that they belong together.

Summary
The Sol Empire is a place of peace and plenty...most of the time. Ten years after the noble hedgehogs of House Erin were scattered and killed in a mysterious attack, a few survivors remain; a blue hedgehog impatiently practices his emerging magical gift of speed, in a hidden location. On the frontline of the Empire's battlefields, a silver-furred hero remains engaged by the bonds of duty, and tears his way up the ranks with channelled fury and grief. The vassal family House Rose were left undisturbed in their own lands, too inconsequential to be worth attacking...until, one day, the long-lost heir of House Erin comes to their doorstep with red streaks in his coal-black fur, and a horrifying tale to tell.
Where has Shadow been? Will the home of Baron Rose, and his daughter Amy, prove a safe refuge? Where was the other heir concealed, to grow to adulthood? And with Imperial Princess Blaze under political pressure to find a husband, will House Erin's hedgehogs once again come to the aid of the Empire when it needs them most?

Summary
Spring. The season most mobians dread. It is the time where omegas suffer heat and alphas go wild during rut. Humans are envied for being able to live their lives without ranks. Some mobians were lucky. Skipping a few springs by being a late bloomer.
Sonic’s rank is unknown. He had missed many seasons. The hero's weakness was not spring. While his teammates suffered, Sonic didn’t break a sweat during the fighting. His senses were centered. His body wasn’t burning. His instincts weren’t interrupting his thoughts.
But then, spring comes around again and he is outed as an omega. Sonic is in denial and doesn’t treat himself properly as an omega. And because of that, he gets in trouble with alphas.

THE ECHO CHAMBERS
PART I: THE SAINT AND THE SOLDIER
History records that Maria Robotnik died on the Space Colony ARK fifty years ago. History is wrong.
She was broken, not buried.
Salvaged from the wreckage of the raid, Maria does not wake up as a human girl. She wakes up as Echo—a fragile, cybernetic anomaly held together by G.U.N. technology and a unstable Chaos Heart.
Thrust into a war she doesn't understand, she spends the eras of Adventure, Heroes, and Shadow chasing the ghost of a shadow she couldn’t save. But as the Black Comet descends, Echo discovers a terrifying truth: Her grief didn't just haunt her—it created a monster.
Now, the girl who asked for peace must become the weapon that ends the war.
A dark reimagining of the Modern Sonic Era. What happens when the martyr refuses to die?“History says winners write the story, but they also never tell about the losses, and in my own experience, loss does not fade away, it only echoes between the pages of entropy’s greatest foe,love that refused to be written out by history’s gauntlets.

Summary
Usually the smut is companion to the world-building, story driven pieces. Not today baybie! These are all side pieces to my reader-insert NSFW villain oneshots. You know that thing where you think you want smut but you end up devouring the story instead? This is the story instead.
All your context for these oneshots is in the NSFW collection. If you don't like world- and character-building in reader inserts, you won't be missing much by skipping these if you're a fan of the NSFW pieces. I won't be tagging this one so much. Like the main fic, the first chapter will be a menu, but unlike the main fic, it will contain summaries and TWs instead of a kink list.
