When Eggman shatters the planet in seven pieces and unleashes a monster that's inside the planet, Sonic must go on a world adventure with his friends to fix the planet and stop the beast. However, Sonic must also deal with a transformation that occurs when the sun goes down, as well as something thats inside him.

Silver shows up in time to stop the Paradox Prism from breaking all the way... but when they try to put it back together, it goes too far, and merges in timelines that split off long ago... (Crossover between all Sonic continuities)

One Shots for Sonic Couples.

Sonic the Hedgehog usually spends his days racing across Neos City, always in the search for the next adventure together with his friends. When trouble calls, be it in the form of aggressive ARNavs, secret government projects, dangerous rivals or the Eggman Empire, there is nothing that will stop Sonic, Tails, Knuckles, Amy, Silver and Shadow from protecting those they care about.

My take on the Sonic the Hedgehog mythos, with cues taken from all over the franchise. Inspired by Mixedfan8643's Sonic the Hedgehog: Heroes of Mobius. Now has a TV Tropes page.

Whisper is about to set off on her first mission as a real Freedom Fighter! Read as she joins Sonic, Sally, Bunnie and Antoine as they raid Robotropolis. The mission's simple! Swing by the courthouse to find the factory layouts for the next mission and stop by Bunnies old home to get her adult size limbs. How difficult could it be?

Mobius is at war, after centuries of peace. Like a long dormant disease, the Eggman Empire has returned and has already laid waste to most of the Mobian populace. In a last-ditch effort to save their world, Mobius' deities enacted a plan to save their world. Unfortunately, that meant friends thought they had died and were separated. This is the story of the New Freedom Fighters.

In the original canon of Sonic, Maria is gunned down by G.U.N. when she and Shadow tried to escape, which acted as motivation for Shadow's revenge. But what if... Maria survived? Find out how she did and what happened after in her own story.

In a broken, dying world, Silver must learn to control his powers in order to survive. With the help of his mentor, he must brave the dangers of the deadly continents and find the Chaos Emeralds before it is too late...

Five years have passed since the Metal War. When war hero: Sonic the Hedgehog, finds out the infamous Dr. Robotnik has resurfaced with a new scheme that puts the world at stake, he sets out with his two-tailed best friend: Miles "Tails" Prower, to stop the nefarious monster. New friendships will be made, rivalries will be forged, and limits will be pushed.

As the fan-made PC version of "Sonic the Hedgehog (2006)" is being developed, there are limitations as to what can be done to the story. As such, this Fan-Fiction intends to answer the question (in terms of the story), "What if Sonic '06 was good?"

When Sonic's world is struck with an ecological crisis that no amount of spin-dashes or homing attacks can counteract, the many civilians and powers that be rally to hold society together through a new dark age. Witness numerous different accounts of tales from far and wide, of living in this new, harsher world - from new and familiar faces alike. Rated T for dark themes.

War is over, Robotnik's gone, and everyone is trying to move on. Well...not quite everyone. For certain hedgehogs, the past is all they have to cling to. Elsewhere, the new GUN Commander isn't as ready as his predecessor to let bygones be bygones.

Years after the end of the war between the United Federation and the Kingdom of Acorn; a young teen orphan called Sonic with his powerful speed will end up starting his journey as a hero as he faces the robotic army of the scientist that destroyed his home and family.

Sonic grows bored when there is nothing to do. He soon comes up with a plan that will release the boredom for not just him but for his friends too. Join Sonic and his friends, as well as his enemies, on this whacky adventure. Rated M to be safe and will have some rather unusual elements to it as well. Also has Sonadow in too.

Better summary on my profile page. Sonadow and rated M to be safe. Sonic is a wearwolf that changes every sunset and Shadow is a demon sent to stop someone from summoning demons out of hell. The two get together very quickly and both work together to help figure out what is going on and to stop it before things get dangerous.

Sonadow. An adaptation to 'A Vampire Love For A Mortal' with a similar setup but also being different. Sonic and Shadow are married, live together and are well known to both species. There is a group of people going around de-fanging vampires and the couple find themselves involved. It soon becomes a race against time to stop these people and save the victims before it is too late.

Unusual circumstances bring Restoration fighters Jack the Wolf and Cyber the Canary to a city called Cwcville...But something seems off. Can they figure out the mystery AND save the town at the same time? Sonichu and all related characters created by CWC. Coldsteel the Hedgeheg created by blood skull boi84.

A day out at the beach, a kooky cat girl, a two-tailed fox and a bottle of sunblock… Wonder where THIS could be going? Tails x OC. One-shot. Fluff. Massage. (Also on DeviantArt!)

Sequel of Sonic and Eve the Hedgehogs: Revenge of the Iron Dominion. Sonic and Eve are back with new adventures, meeting familiar and new friends and enemies. They'll also travel to familiar and new worlds, along with plenty of struggles and wild and crazy adventures.

Taking place fifteen years before the events of the Second Great Dimensional War and the Big Sister story, this wholesome story follows the 'relationship' of Miles Tails Prower and a nine year old child super villainess named Scylla 'Aria' Bradanska the Fox while the kid fox prodigy encounters her while returning home from the parts store for his plane.

At Station Square University, Sonic and his friends navigate the trials of college life and adulting. Some have come seeking a fresh start and get more than they expected. As friendships are formed and rekindled, so are enemies. Will sparks fly? Knowing these guys, most likely.

When Rouge is attacked by a strangely mutated panther while on a mission in the Mystic Jungle, she and her partner Shadow are tasked with investigating a mysterious ancient temple and uncovering the many secrets the forest has to offer... all while battling their own inner demons.

The third story in the Cyber Riders series. With Nack gone, crime lord Jem raises the stakes for the newly reinstated freelancers as a harsh winter starts to settle in. What does Jem have planned and can Sonic, Tails, Knuckles, and Shadow stop it in time? Read and review, please no flames.
