Summary
Cos knows he’s funny, a flirt, a wise-guy, a quick-step, a romantic. He's always had Don, and he knows he always will. When Kathy drops into their lives (or, he should say, Don drops into her car), he has something new to know- that he'll always have Kathy, too.
A canon-compliant retelling of Singin' in the Rain- except that Cosmo and Don both fall in love with Kathy, because loving each other is as easy as breathing.

Summary
There was an idea, Tony Stark thought of it. It was called: The Next Avengers Initiative.
The idea was to bring together a group of remarkable young people. The motive behind it was that in case anything happened to the original Avengers, they would rise and become something more....and fight the battles that normal people never could.
It may be old fashioned, but it still is true.

Summary
For centuries, Santa Claus has been the icon of Christmas, a jolly figure who gives gifts to all the nice children of the world and punishes the naughty by only giving them coal. But there used to be another figure who handled punishments, and he was a lot harsher about it, so much so that Santa eventually drove him out... until now.
Krampus has returned, and he wants back in on the holiday. And to do so, he sets up a bet with Santa - using a new system of punishment he's devised, he will break some of the worst of the naughty list, and make them desire to be better and help out those on the nice list... in every way possible~
Will he succeed? Or will these naughty girls resist their punishments?

It Really Sucks To Have Friends by TheGreyCoincidence

Summary
Formerly Two Thirds Of A Dream
Making a conscious effort to bury any demons of his past for their sake was something altogether too mushy a thing to tell the rest of the Guardians about. But Rocket's life was practically two thirds of a dream now and he was not going to screw it up. His friends would have wanted him to be happy. To live out the dreams they'd dreamed together in the dimly-lit cages they had called home. Of course the problem with dreams was that sometimes you woke up and found yourself staring down a nightmare.
Or...
The insane lengths Rocket will go to to save his friends from their creator's clutches when they return to his life in the wake of Xandar. It would be a hell of a lot easier if they frickin' remembered him. And a hell of a lot easier if his new friends didn't keep getting in the way.
A Batch 89 Fix-It... sorta

Summary
When Makima died, her control over Quanxi ended- but that’s not the same as being free. Blackmailed into serving Public Safety, Quanxi survives on the hope she might one day bring her lovers back, numbing herself to the grief before it overwhelms her.
But it’s hard to ignore what’s in front of your nose. When Public Safety assigns Quanxi as handler to the unruly and defiant Grief Fiend, she won’t be able to avoid her pain for much longer.
Still, things could be worse- at least the Grief Fiend is a cute girl.
————Largely canon compliant up through book 16. This is an emotional catharsis and eventual unbury your gays fic. There’s gonna be a lot of pain but a happy ending. Expect piles of lesbian sex, a good chunk of drama, all my fan theories, and action scenes which will hopefully improve as I go.

Quanxi is given the offer to come out of retirement and become the new teacher for UA's new Quirkless Combat curriculum. She accepts and takes her four girlfriends with her on the journey out of China and to Japan's most prestigious hero school, a place where she might get more than she bargained for!

Summary
Don and Kathy would move in together. They would have a dog or two and then inevitably, a small parade of adorable little brats who would call him Uncle Cosmo, and they would spend less and less time with him, not on purpose but busy with the rest of their lives, and ultimately Cosmo would learn to make his peace with it because he’d have no other choice and he would have to try to move on and not live too much in his memories. He could picture it so clearly, he figured if the songwriting gig with Monumental didn’t pan out, he could always return to the backwater circuit with a new act: The Amazing Cosmo of the Cosmos—ladies and gentlemen, he sees the future, he reads the stars, he silently pines for his best married pal and all the while tap dancing!
Don and Kathy inviting him along on their honeymoon, though—that part was a surprise.

In this Twilight, Our Choices Seal Our Fates by EmmaSmoke

Summary
Silver the Hedgehog has been fighting against the apocalypse for seven long years. Finally, he and the remaining mortals initiate Operation Argus to save as many lives as possible. Silver is the only one left behind to destroy everything that remains. But his success is short-lived when the darkness of the east—Mephiles—forces Silver to turn back time.
Back at eight years old before the apocalypse began, Silver endeavors to stop it from ever occurring in the first place. His first step is to kill Emperor Shadow of the Doom Empire, the one who unleashed Mephiles in the first place. Unfortunately, Silver isn't strong enough to kill Shadow, and he, in turn, can't kill Silver because he's... Shadow's blood?
It wasn't in Silver's plans to become an imperial prince, but he decides that he can use this. He'll stop the apocalypse, no matter what it takes.
