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.

Summary
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.
— dr Gerald robotnik

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.

To save the world, he may have to sacrifice the very thing that makes him who he is.

Summary
Professor Gerald Robotnik had created the ultimate life form in his experiments with the black arms genes in the form of Shadow the Hedgehog.
However, despite how much promise Shadow showed, it still wasn’t enough to be able to cure Maria Robotnik of her terminal illness, and he still had no idea how the black arms genes would affect a human.
Professor Gerald would create another ultimate life form using Maria’s DNA mixed with the black arms genes to make an artificial sibling to test how the black arms genes would affect Maria.
Follow James Robotnik’s story through the space colony ark and early life on Earth as he tries to reconcile with who he is, uncovering the mystery within the zone of an almost apocalyptic region of the country James inhabits. Facing off against humans, mobians, and mutants alike.

Summary
Somewhere in 2017, Sonic Forces was created. This has made a lot of people very angry and been widely regarded as a bad move. And then, one Thursday, nearly five years after one man had been nailed to a tree for saying how great it would be to be nice to people for a change, a hedgehog resting against a tree somewhere on Mobius suddenly realized what it was that had been going wrong with the series all this time, and he finally knew how the world could be made a good and happy place. This time it was right, it would work, and no one would have to get nailed to anything.
Sadly, however, before he could reach his friends to tell anyone about it, a terrible, stupid catastrophe occurred, and the idea was lost forever.
This is not his story.

Summary
Hollywood, 1950.
The nights are filled with Sonic’s voice, brilliant and fleeting, like the flash of light reflected in an empty glass. Everyone adores him, yet no one truly knows him. Shadow watches from the dark, performing his duty as a guardian, untouched by the world he’s sworn to protect… until he hears him sing. And something within him falters. Among the echoes of jazz and the secrets fame refuses to forgive, two lonely souls meet on a stage that was never theirs. And when love is born in a place built on illusion, it can only bloom as a quiet tragedy.
