Sonicau Stories

What if Nine was responsible for the creation of Rusty Rose and before she was ever a cyborg the two had a brother and sisterly relationship. Things go good for the two of them until the Choas Council kidnaps Rusty and corrupted the fox's sister for their own personal gains. Now It's up to Nine and Sonic to rescue the cyborg hedgehog and help restore things to order.

Welcome to a completely reimagined Sonic universe. Divided by a great central sea, the world is split in two: on the left lies Mobius, home to vibrant landscapes and animal citizens. On the right lies Earth, a bustling realm of human cities. While the two sides live in harmony, the heroes who protect them are dealing with secrets of their own. To the public, Sonic the Hedgehog is the ultimate hero-cocky, fast, and wielding powerful aerokinesis. But behind his snarky grin lies a heavy mask, hiding the scars of an abusive past. Saved by his loving mother Aleena and his unexpectedly caring new stepfather, Dr. Eggman, Sonic is finally trying to heal. Alongside his traveling rockstar brother Manic, his kind-hearted sister Sonia, and his fiercely protective, half-demon boyfriend Shadow, Sonic is building a life of his own. But peace never lasts. Organized into three-person teams across the globe-from Tails running his cross-sea boat business to Vector operating a booming detective agency-the heroes of Mobius and Earth must balance high-society drama, secret crushes, and domestic life. With a dangerous threat looming on the horizon, can Sonic keep his mask from cracking, or will the ghosts of his past destroy the new home he has fought so hard to protect? ✨ Note for Readers: This series is a long-form story structured by seasons! Expect a dynamic mix of high-octane, action-packed plot seasons, followed by entirely cozy, Slice-of-Life seasons focused purely on comedy, romance, healing, and domestic fluff

Emilia and Cataleya, subject to a brutal regime in their home of Astreusa, flee total destruction and stumble across a civilisation they never knew existed. Meanwhile, Kira and her family have settled in with Bitobian society in the years since Shadow Linnea's defeat. Little do either of them know, things are more connected than they might think.

Engineered in a sterile lab by the spoiled, perfectionist Dr. Starline, Haz (17), Surge (15), and Kit (10) were created for one purpose: to replace Sonic, Tails, and Knuckles. But Starline severely underestimated the free will of his first prototype. Haz-a deadpan, agender long-eared hedgehog with a strict three-strike rule for their pronouns-broke out of stasis, rescued their younger biological siblings, and fled into the deep woods. Now, they live life on their own terms: roughing it under a camp tent, scraping together golden rings for survival, and healing from intense laboratory trauma over midnight stashes of spicy hot chips, raindrop cakes, and crunchy crystal jelly gems. They are the ultimate antihero pack. They don't mind ruining the Freedom Fighters' plans, and Haz will happily land a heavy, earth-shattering punch right to Sonic's cocky face. But their peaceful outlaw life is under contant threat. Between dodging the clever, shape-shifting criminal Mimic the Octopus, they suddenly find themselves hunted by a terrifying new apex predator: Null. He is a walking void wolf who steals powers, howls at the full moon, and tracks them entirely by scent. Can three runaway teenagers defend their campsite from the ultimate cosmic threat? Or will they find out that the terrifying void demon just needs a little bit of bacon and a belly rub to become part of the family?

what do you do...when you realize there's nothing left? there's no reason in what your doing... why continue? sonic and Scourge come to think what's the point? and why bother? and leads to an odd turn of events Why did Sonic let everyone down he's family his friends everyone? why'd Scourge make the decision he did? who's the corrupted one in the Zone Cop force? who can they trust? and what the actual fudge is "Mowobius"?! all your answers are in this book An AU where things aren't like what they were and there's a big twist in the hero's and villain's you know BTW it doesn't waste time to get to the real plot nothing belongs to me or other Fans unless I say otherwise and if you got lost at "other Fans" read my Bio oh wait ShadowGhost1000 Drew the Cover for me I hope you enjoy the Story

There will be violence/gore. And Sonadow might be presented in this story but nothing too big. Shadow the hedgehog, was made from a lab. Sonic also a hedgehog, was discovered by this lab facility and was taken very young. And due to trauma and being young he can't remember exactly where he came from but he had a special power of speed. The lab thought this was fascinating and kidnapped him. After doing many tests and failing at times, they made Shadow. Tests were done on them and there purpose of them were to make them into living war machines. Instead of doing an antidote, they made these electric bullets. When these bullets hit shadow or sonic. It makes them transform into something of a monster. This triggers something in there body to do something almost like a werewolf transformation. There claws extend, there muscles grow, they become bigger, the color in there eyes become black, teeth extend, and there strength multiplies. But they become not there self, they get out of control and blinded with what there doing. They attack anything in sight, killing even. But the lab was destroyed by GUN before they could use them as there war machines. But remains were left of the lab. Eggman ended up finding the remains and saw the "blue prints" for how to make these bullets. Eggman created his own design with the bullets and fused them in his robots using it against Sonic and Shadow making them go out of control and go against there own friends. But of course there are limits of the transformations. There body can only take so much before turning back to normal. And fighting and getting beat up and exhausted makes the process faster to go back to normal. It's hard to get them out of the state there in but getting knocked out, fighting, get injured.. etc will help to turn back to normal as long as there not hit will another bullet. But now to many bullets at once can result to death. Sorry if this is to long but it's hard to fit it all in ^^

Read the damn title

Heyo, paisatos! Mario Velocità here! Ever wonder about the zany adventures I get myself into? ...No? Then too bad, I'm gonna tell you away!

Being happy doesn't mean you lived a happy life, it could be a defense mechanism. Don't judge others, you don't know what they're hiding anyway. ⚠️Warning⚠️: This story contains violence and gore. The names in the story do not mean offense to anyone as well, I swear. If it's offensive, please tell me.

An eccentric tale taking place about 5 years after the main events of the Sonic IDW verse, with some addons from the Archie Comics--after all, who doesn't like a multiversal story? As the title suggests, we see Sonic the Hedgehog's exciting development as he goes from chaotic good to outright chaotic evil. So, where does the changing point start? Who does he lose? Well, what are you waiting for?

"It's dangerous to wish I could make choices of my own. Dangerous, to even have that thought. I'm dangerous just standing here, for everyone to see. If I let go of rules who knows how dangerous I'd be?"-Dangerous to Dream from the Broadway production of Frozen. This is a Sonic Unleashed twist ending AU that came to me that I ended up liking! The cover art was drawn by me! You know how it goes: Sonic, turned Werehog, recovers the Chaos Emeralds and pieces the world back together again with his companion Chip as the two team up to seal away Dark Gaia from destroying it. This story is different though, for it's not what you think it is. What if Sonic had to become Dark Gaia to save the world? Instead of losing the energy zapped into him, Sonic absorbs more of it to the point where he transforms into Dark Gaia itself after loosing his Werehog form. With the last bit of his sanity, Sonic sacrifices himself to save the world that he once knew and loved, casting away his old life in the process. The years pass with many thinking that Sonic is, well, dead. Except for his friends. They want to find the proof that he's still alive, and that they can bring him home safely. During those years, Sonic has grown attached to his new life as Dark Gaia, the Earth god of darkness, counterpart to Light Gaia, and caretaker of Abyss. Sonic one day hoped to return home, but knows that he can't, which was the only con about his new life. The pros being that he had Chip, his son Lucius, and Abyss with him through thick and thin, as well as being able to perform magic. When Sonic finds out that he could travel to the surface world and change back into his normal self, he does so to be reunited with his friends. Now Sonic must face the challenge of balancing his double life as the famous blue hero on the surface and being Dark Gaia underground. He has to keep this all a secret from his friends, including his nemesis Dr. Eggman, but can he do so before they find out?

Pt. 2 to Sonic x Shadow Friendship Hell What happens when the love you've been Dreaming of is waiting for you at your dorm room door? You make it reality of course! The only problem is that realty is never as good as fantasy. Sonic's done something unfathomable, just downright despicable. Follow shadow as he traverses this relationship turmoil in this short but utterly fascinating drama. Filled with fun, makeovers, regrets, and romance! ... Summer vacay started. I'm bored and no longer writing for classes. all projects after this stupid Sonadow one, if there are any, will be better. swearsies.

Sonic is born sickly/Terminally ill in this AU, doctors can't exactly figure out why. He's perceived as weak by everybody around him and becomes a regular target for all kinds of harassment at his high school and in his own household. He somehow discovers that he's developed super speed that doesn't take up a lot of the little energy he has and uses it to his advantage, and it eventually changes him. (I never know how to put covers on my stories that don't look cringe, so please remember that even if the covers of the stories are sorta goofy, I take the stories SERIOUSLY, don't be fooled by the cover.) (I'm somewhat new to fanfic, but I'm not 100% ass at it, so please shed mercy and don't verbally cut me into pieces in the comments)

What if Mimic, at the last minute, chose to turn against Eggman once more and save the lives of the Diamond Cutters? What effects would be felt if this freedom-fighting team were never disbanded and met the rest of the Sonic cast? Prepare for found family, gay ships, and fluff! Ships are Whispangle, past Whisper/Claire, Slinger/Sonic, and Mimic/OC. AU originally owned by @hamatopurity on Tumblr, but I came up with ideas for it as well. She has given me permission to write fanfics for it.

this is just a filler story for the "Beast" one! just wanted to make telling a bit of her life and who she is! and why she saved "Sonic", thought it would be fun... enjoy!

Idk, but generated by one of my give AIs
