Dr. Eggman invented a serum that will make the injected person act upon their deepest desire. He believed that Shadow's was to kill Sonic. Boy, how wrong he was... [eventual Sonadow]

"I made a name for myself so that you couldn't call me just an 'evil twin'. No matter how much you beg, no matter how many people I have to kill, I will never stop. And there ain't a damn thing you can do about it, Blue. I'm just trying to help you." Sonic just wanted to go on a short vacation. It's funny how quickly the world can fall. Mainly Sonadow, some Sonourge.

Sonadow- Sonic could be male, female, or a cuntboy; depends on my mood. These lemons will be long, short, or in between. This is not made for request, but I will allow them! Enjoy! Sonic-Uke Shadow-Seme •If you have problems with this, I don't care, don't read and carry on with your crappy life•

While Shadow knew that things wouldn't go back to the way they were before the doubles crash-landed into his reality, he believed that a new normal could be achieved. However...no one could've imagined the devastating storm a simple empty grave would brew. Rated T for language and violence. Third installment of the Alternate Reality series.

Knuckles has Tails make special inhibitors for Sonic after an incident where he went Dark and lost control. Now, Sonic must get used to the constraining feel of the inhibitors as they force his body to ignore the Negative Chaos Energy inside of him. After getting frustrated with the way they make him feel, he turns to Shadow for help...

When Tails has a nervous breakdown during a routine mission, Sonic worries about his best friend's state of mind. When a mysterious stalker targets his friends in pursuit of the Chaos Emeralds he has to put his doubts aside for Tails' sake, but as danger creeps ever closer, Sonic is faced with a terrible choice, one that could destroy his friendship with Tails forever.

It's amazing what we take for granted until it's gone, left to pick up the pieces. But will things ever be normal again? There's no way for the former blue blur to know, but a certain reluctant black and red hedgehog might be able to help him along the way. Sonadow, some violence, light swearing, maybe a little blood in later chapters so rated it M to be safe.

He's been drowning for a long time. And, somewhere along the way, he's forgotten how to breathe.

When a terrible storm traps the members of the Resistance inside the Mobian Castle, boredom is unavoidable. To pass the time and maybe have some fun, Sonia pulls out an old board game their mother left behind: Truth or Dare. The game starts out innocently enough, until Sonic pulls a dare card and refuses to do what it says. Unfortunately, they don't have a choice. AU. Sonadow/Other

[collaboration with the-enigma-machine] Sonic has always been the fastest thing alive—that is, until one encounter with Dr. Eggman changes everything. Now permanently transformed into a werehog, even in sunlight, Sonic feels like he has nothing left. Though, soon after, Sonic suddenly finds that the one who understands him most might just be Metal Sonic.

(Sonadow Short Chapter Story) Rated T for mild violence and cussing. Simply, this is a short story about two hedgehogs, how their relationship started, then later a mock battle and some fluff. Should be around 3 chapters when finished, takes place around Sonic Heroes time maybe, but for sure after Adventure 2. Read, review and enjoy!

Shadow is a mushroom, and Sonic is just tired.

ALL CHAPTERS EDITED! Sonadow; Mephilver and Fleetourge in later chapters. Real description in ch. 1. Sonic gets kidnapped and is brought on an island, where hedgehogs are forced to breed by an organisation of humans. Only one hedgehog doesn't seem interested in raping him. Can he escape this hell? Rated M, will contain rape and heavy stuff.

Through all of his adventures, Sonic has never questioned himself or his powers. His speed, his affinity for chaos energy, everything else - they don't usually matter in the long run. But that doesn't mean he misses the signs.

Metal was programmed to do nothing more than fight Sonic. He feels nothing but contempt for the hedgehog, as his sentience only allows for negative emotions (that's how it works, right?). Thus, when Eggman demands that Metal go after Sonic, Metal sets off to do so. Sonic, however, is just as uncooperative as ever.

Underground/Mainstream. It's been years since they've seen him. The kingdom has rose, but one is missing. When they get him back he's different. More damaged. Coming back seems to have wrecked him more than any badnik. Will the Sonic Underground become a family again? And what about Sonic's friends? How do they fit in?

Adopted from CeruleanWind, Shadow must embark on a mission, but Rouge isn't here with him this time, so he's forced to take Sonic instead. They hate each other, down to the very guts, but as the mission continues and they become lost in the wilderness, they must work together to survive the deadly harshness of the rainforest and the mysterious creature following them. (Sonadow)

Durante 4 años, Shadow ha usado un anillo matrimonial con el cual ha fingido estar casado para evitar que le rompan el corazón. Cuando asiste a una fiesta se enamora de una eriza llamada Maria y para ganarse su amor, le pide a su asistente que finja ser su 'marido' para convencerla de que se están divorciando. SONADOW

Love is when you care for someone more than yourself, and you would do anything for them to be happy, alive, and well, no matter what the cost. He wasn't supposed to fall in love with his rival. He wasn't supposed to let things spiral out of control. He wasn't supposed to let the other get away with everything...but he does, because he loves him, no matter what the cost. Sonadow.

Deep below the waves you may find a way to leave your world behind. Where creatures crawl, with dinner on their mind, your only chance is to hide. You may scream, you may shout, but do you have what it takes to make it out?

Sonic and Tails are trying to find a foreign object that keeps appearing and disappearing throughout Mobius. Tails takes off to rest while Sonic ventures out to find the mysterious object that supposedly is some sort of a car. He later finds it and is surprised on who he sees in the vehicles. Both of them travel to another dimension to take care of some business. (Sonadow)

You know what they say... opposites do attract. And, that's exactly the case with Sonic and Shadow. Sonadow. Don't like? Don't read! Full of adorable fluffiness, because that's what I live for.

In which Shadow wonders why so few Mobians have an actual surname.

If you asked Sonic what words he'd never use to describe Shadow, among these words would definitely be the word 'clumsy'. Considering that Shadow had been exactly that for the past few days, it is obvious something isn't quite right.

Sonic has been missing for over a year and Tails has begun to become concerned. Whilst this is a problem a more immediate concern is the sudden disappearance of the Chaos Emeralds. Even Knuckles cannot find them using the Master Emerald. Where has Sonic gone, is his disappearance linked to the Emeralds? My first ever fanfic, so reviews will be greatly appreciated.

"I love you Shads..." "I lo-" His warmth and presence disappeared and I let out a cry of frustration and heartache. Sonic can no longer deny his feelings for Shadow, who he knows will never return his feelings. So Sonic goes through depressed moods and it's up to his friends to find out what's wrong and how to help him. If only Shadow would help...

Sonic's running from his past. Shadow's looking for answers. And Knuckles holds all the cards in the deck, even the ones that don't seem very important until they ARE. Just a bunch of Oddities, that's what they are.

It's the holiday season, and it's been very long since the adventures of Sonic and friends. Shadow finds himself one of the few left out of them. Cursed with longevity, he finds the strength to go on in his adopted son, who happens to be young Silver. However, a trip to the cemetery gets him very emotional, letting some intrusive thoughts creep in. Written for a Secret Santa thing.

There are many rules for a Knight, one is not to love an outsider, so what happened if one does fall in love with an outsider?

Sonic, Tails and Knuckles are trapped out in the middle of the desert, injured, and vulnerable to Eggman's attack. Will they all make it to another victory . . . or will they perish? What would have been, might change.

SONADOW. After Chaos Control goes awry, Sonic and Shadow go AWOL...landing in a parallel dimension with many familiar faces, but a huge problem. Getting back would be so easy - that is, if everyone wasn't insisting that Sonic is 'Prince' Shadow's slave...

...chaos would ensue.

Los deseos sombríos surgen de las brillantes y puras intenciones. El causante del caos debe atenerse a las consecuencias de lo que ha hecho con La Forma de Vida Perfecta. Pairing: Sonadow/Shadonic [Shadow the Hedgehog x Sonic the Hedgehog] Advertencia: BL/Yaoi, Sad, Hurt/Confort, Gore

Sometimes things didn't always feel quite okay, though. [post-forces]

As a couple, Sonic and Metal make a formitable team, and it's all Eggman can do to defend the core of his empire from them. And yet, when Sonic and Metal try to restore Oil Desert Zone, Eggman proves he's still very capable of counter attacks.

In which Shadow's a reckless idiot and Sonic is kind of panicking.

Sonic the Hedgehog had many titles. "World's Greatest Explorer" was just one of them. Never hesitating to jump down any cavern he found, Sonic never delayed if it meant finding something cool. Which is exactly what Lost Labyrinth gave him.

It was six months before they found him.

Sonic has something on his mind and decides to talk with Amy about it. T for talks about sexuality.

"Say, Sonic, why did you decide to call your plane 'Tornado?" "It's what everybody used to call my mom."

After Shadow uncovers a living weapon within one of Eggman's bases, he comes across Project: Chaos, who Shadow dubs "Sonic" after rescuing him from termination. However, there is more to Sonic than meets the eye and soon, Mobius is under dark siege by Eggman's forces. Not only that, but it seems Sonic has links to a mysterious pocket dimension known as Null Space...

After a challenging date with Amy, Sonic wants nothing more than to hide in his house. Problem is, Amy drugged him with an aphrodisiac. Sonadow.

Shadow only wanted to make sense of his fractured memories. He didn't ask to be some magnet to the supernatural, or to be Bound to an unstable vampire with a specific taste for his blood. But the more he spends time with Sonic, the more he learns the two share a past that neither can remember... and that he himself isn't as normal as he looks. Vampire AU.

Sonic gets a sudden request from Mighty and Ray to help with a mission, but nobody is prepared for the events that follow. A slow burn Sonighty fic.

After a frozen skirmish leaves Metal Sonic questioning his identity, Sonic decides to step in and help guide Metal to his own self-discovery. But when Metal realizes he can only feel sensations from Sonic, he approaches Sonic with a single request.

Sometimes Sonic had nightmares. Sometimes they felt too real. [oneshot]

Faced with a crisis that threatens all worlds, Shadow and Maria are called upon by Goddess Aeon to collect the 300 Soul Plates to defeat a powerful being known as Infinite. Teaming up with psychic Estyn, pyrokinetic Lara and electrokinetic Volt, Shadow and Maria, alongside a traumatized Sonic, must save the universe but it seems fate has other ideas...

It's not that Metal didn't want revenge anymore. He certainly did. After losing to Sonic multiple times, he's sworn violent eternal revenge on this hedgehog's existence! Which, unfortunately, didn't explain why he's currently holding Sonic in his hands right now.

Young Sonic has been an outcast his whole life. He is a hermaphrodite, and is unfortunately taken advantage of constantly by his master's many clients. Shadow and Silver are princes. Their father is requiring them to get a slave so that they can prepare to govern the people. What happens when Sonic, Shadow and Silver meet?

When Shadow started dating Sonic, he had not expected that the relationship would double as a course on the hedgehog culture too, but then again Professor Gerald nor any other of the human scientists on ARK had been knowledgeable enough about the cultural heritage of either of his biological donor species to teach him about it themselves.

He didn't care if Sonic saw him. The faker couldn't use this moment to tease him later on either way. Sonic wasn't going to exist later. (Sonadow/Shadonic)

Christmas is the time to really think about what you have, and how much it trully means to you. Oneshot. Sonadow/Knuxouge/Silvamy.

When a sudden rainstorm and a profound administrative misunderstanding force Sonic and Metal Sonic into the same hotel room, the two of them try to pass the time in the only way they know how: competition.

After a rough week, Shadow tries to get a relaxing day in, until he allows Sonic to show up for a visit. After sharing a secret with him, what road will come Shadow's way. Sonadow, Shadic, whateve. Warning: yaoi, sex, and raping. UP FOR ADOPTION

(Mythological!AU) Shadow knows there are pressing matters he needs to take care of — and yet he still cannot bring himself to walk away, too fascinated by the strange nymph that just seems to love throwing him for a loop. [Sonadow]

Metal Sonic was created with a single purpose: he was to neutralize Sonic the Hedgehog. Now he is trapped with Sonic and lost in the deadly maze of a madman. In order to escape, he must cooperate with his most hated enemy, yet still follow his programming to its logical conclusion. Metonic (Sonic x Metal Sonic)

SONADOW. A missing scene from 'He Is My Master' when Sonic and Shadow are trapped for the night in the dungeon of a foreign dimension, and execution is scheduled at dawn. Bonus Story 'The Value of Rarity' at the end.

ON HOLD: This wasn't supposed to happen! I just wanted to foil Eggman's plans. Why did it turn out to be like this? Will I ever...move on? WARNING: SonAdow
