Summary
When a Phantom Ruby experiment spirals out of control, Sonic, Dr. Eggman, and Sage are hurled through a rift in space-time — crash-landing in a world that shouldn’t exist.
It’s a darker Mobius — one ruled by the tyrant Dr. Robotnik, a brutal dictator who’s already won. Freedom Fighters hide in the shadows, machines patrol the skies, and Sonic’s face is plastered across wanted posters worldwide.
As Sonic struggles to ally with this world’s battered resistance, and his own injuries, Eggman comes face-to-face with his own counterpart — and sees not an equal, but an opportunity. Two brilliant, ruthless minds joining forces could mean the end of both Sonics… and the rise of an empire spanning dimensions.

Summary
“Um, excuse me, Miss Tour Guide? One of the spiders is missing!” Amy called out, her hand raised, before pointing at the terrarium in question - which was, in fact, devoid of a spider.
“Oh. Well, rest assured, I’m sure one of the researchers here has taken it for further testing, so don’t be alarmed.” The tour guide continued, and before Amy could open her mouth to ask any questions about what kind of tests they’d be conducting on the spider, she moved on to explaining some of the other spiders in the terrariums.
Sonic slumped, suppressing a groan - he couldn’t wait for this field trip to be over already.
Then, he suddenly felt a sharp pinprick of pain on the back of his left hand, yelping and turning down to see a spider had bitten through his glove. With an annoyed (and a little pained) huff, he swatted the spider, watching its crumpled form fall to the ground.
“You good?” Knuckles asked, the only student who was close enough to hear him yelp.
“Y-Yup! Yup. All good!” Sonic said quickly - he’d never live it down if Knuckles found out about him getting bitten by a spider almost immediately after talking about a missing spider. It would just be so embarrassing.Or: A Sonic x Spider-Man AU :D

Summary
Eggman has known this kid for just over a year. Hardly knows him really. All he does know is this kid is a real pain in his side. And here he was, offering the hedgehog a place to stay over the cold winter months.
Was he going soft?
No. It's just temporary. It means nothing. The rodent is only to stay until the snow starts to melt. That's it. It. Means. Nothing.
So why did he offer to begin with?

Summary
Sonic and Tails, from the beginning to end. Surely nothing will go wrong in their time together?
Every good story has a beginning, middle, and end. Great stores make you question if it is over, until you turn the page to find yet another chapter. Great stories throw the reader for a loop, confuse the reader, and then explain everything, making it look like you should have known from the beginning. Great stories have a second meaning when you read it a second time through. when you know the ending and you pick up on all the little cues that you have missed before, that make the end result you puzzled over seem so obvious. Great stories entertain, yet make you think.
I hope to write a great story today. -

Summary
After a tragic accident, Sonic, only 6 years old, was left to wander the wrecked streets of what was once his home. He was found by Dr. Eggman, who took him in. Although Sonic never really viewed him as a father, they were still family in a way.
Growing up, Sonic would often run away from home and cause trouble in the city, giving him a bad reputation and causing G.U.N. to start hunting him down.Shadow was 8 when G.U.N. invaded the ARK and killed everyone involved with Project Shadow. Maria sent him down to Earth before she was killed, and Shadow was taken in soon after, the commander deciding it a waste to kill him in the end. Shadow’s memories of the event were fuzzy, so over time, he eventually gave up trying to remember, instead focusing on his training alongside Rouge.
Shadow has now been tasked with taking Sonic down and bringing him in for containment. Though, it isn’t as simple as he had thought. Sonic’s speed and strength rival his own, and his actions are erratic, unpredictable.
At first, Sonic seems like nothing more than a complete adrenaline junkie. But as Shadow digs deeper, he starts to see there’s more to Sonic than just reckless energy—layers of complexity he hadn’t expected. -

Summary
After years and years of victories and losses against the blue menace that labelled himself a hero, Ivo Robotnik had learnt a thing or two about his behaviours and patterns. As much as he hated to admit, he knew that he’d never be able to catch Sonic off guard without a significant advantage, and in this case, all he needed was for one of his new inventions to get close enough to latch on. So, he kept hurling eggbots, robotic claws, bombs, lasers, the works– all until he managed to create one key opening.
Or, Eggman gets the chance to kill Sonic, but Tails prevents it
