Summary
Even though he’d grown up for a good portion of time without them, finding his triplet siblings Manic and Sonia was the best thing that ever happened to Sonic.
Saying goodbye to them was the worst.
After a failed mission to get their mother back ended in disaster, Sonic decided they needed to switch tactics. The only way to do that seemed to be splitting up, as much as they all hated it.
Now it had been five years, and he hadn’t seen his siblings since that day. Sonic was living out his days in a beach hut on some unnamed island, keeping things steady and laying low. Until Sonia and Manic show up out of the blue with the first new bit of information they’d heard about their mom in years, and the peaceful life Sonic had come to know disappeared in an instant.A song-fic set on the Sonic Boom Island but with Sonic Underground Background. This whole funky little universe is inspired by a random text my roommate sent me that said "Sonic Boom Sonic is def Sonic Underground Sonic and the bandana is to cover his necklace" so that's what we're working with.

Teaching an Edgy Hedgehog How to Behave (by interfering in an established relationship) by cheariys

Summary
"What if we open up our relationship?"
A simple question that, upon agreeing, he didn't know what it would unleash. Sonic wasn't sure if Shadow could fit into a relationship built on years of playing cat and mouse, years of holding back for fear of being deprived of his freedom, years of feeding the belief that it was one-sided. Now, with Shadow, he'd have to grapple unpleasantly with the fact that he's a bit hot, so it has an effect on him. Amy is no stranger to those effects either, so they agreed to monopolize him in their relationship before anyone else.
Living with Shadow wasn't the best thing that had ever happened to him, but at least they could teach him how to be less of a jerk while falling in love with him.

Summary
"Can I hold it?"
Shadow slowly turned his head, face screwed up in a deadpan grimace. After a pregnant pause, Shadow asked, "what?"
Sonic's smile grew brighter- impossible at such an hour, but he digressed- and replied with a chipper tone, "I said, can I hold it?" He even had the nerve to look proud of himself for such a question. Shadow's not sure if he was impressed or disgusted.
"...No?"
"Ugh, you're no fun!" Sonic threw his hands up in defeat.

Summary
Behind the scenes of the Sonic franchise, Dr. Eggman has been awarded the responsibility of policing the official canon, and helping to make sure that fraternization between canon characters, non-canon characters, and retired characters is strictly managed. Naturally, he begins abusing this power almost immediately.
Bunnie Rabbot and Rouge the Bat have recently fallen in love, however, and are determined to stay together... no matter what the Canon Compliance policy has to say about it! Can their budding romance survive Eggman's police state policies, or will the different realities of characters in the spotlight and characters who've been shelved wind up being too much for them?

Summary
Trigger Warnings:
Transgender themes/struggles + Self Harm + Strong Self-Deprication + many topics along those themesSonic struggles with his identity, and possibly even his whole purpose. Shadow is a silent observer, slowly making his way in and protecting Sonic. Shadow slowly watched Sonic's spark die, and he partly blames himself. He hesitated. He won't make that mistake again. Not with Sonic.
I WILL STATE REAL QUICK!!! : This is based on the movies/Boom *slightly* and the Sonic Prime world HEAVILY. I have made it into a bit of a weird MIX, so the world will be a bit different than any canon universe (with locations/info/etc).
Extra from creator:
I will say that it is very 'sweet' the further you are into the fic, despite some heart-wrenching themes that some people may resonate with! I would suggest that if you resonate too deeply and/or feel uncomfortable by the fic, feel free to click off anytime! For this one, I will not accept comments that criticize the story (ish) just due to certain feelings of my own, driving the entire story in the first place. I WILL take criticism for the writing/etc, though! I will also state that this is my first fic uploaded BY MYSELF. -
