Summary
When Shadow was about to fall to Earth after saving it from the ARK, Sonic grabbed his hand and switched their places at the last minute. Now, Shadow is left with grief and confusing feelings he never asked for. In the aftermath, he's made it his mission to watch over Tails, whose own grief and dangerous mental spiral are all too familiar. But when G.U.N. declares them a threat and Eggman releases a mysterious new weapon that seems to mock their past upon the world, survival will mean more than just fighting: It will mean confronting the pain that threatens to destroy them from within.

Summary
In the world of alphas, betas, and omegas, Surge the Tenrec never had the choice to just be as she was. Starline’s experiment left her an alpha against her will—twisted instincts, tangled hormones, and scars she doesn’t want to face. Pretending not to care can only get her so far when Eggman’s newest plan throws instincts wild and a mysterious force seems to be trying to make things worse.
Saving civilians, standing against raids, watching Kit take dangerous risks—it’s a role she doesn’t trust herself to play. Worse still, every time Amy Rose looks at her, Surge feels that gnawing pull in her chest—a mistake she can’t stop wanting to make again.
As enemies close in and loyalties are tested, Surge has to decide if she’ll run from what was forced onto her… or fight for who she wants to be..
A coinciding story with Fighting Instincts. -

Summary
In a world where mobians are born as alphas, betas, or omegas, Sonic the Hedgehog has always hidden what he truly is. It's a secret he's protected for years—one that could change everything. But when Eggman harnesses the power of the Chaos Emeralds to unleash a wave of primal energy, the balance begins to crack. Instincts rise to the surface, hard to control and even harder to ignore. As Sonic fights to keep the world safe, he finds himself more vulnerable than ever—not just to the threat of discovery, but to the feelings he's buried deep, especially the ones about a certain ultimate lifeform.

Summary
There were two big rules at Chaos Security. Don't fight or fuck your clients.
Shadow had been in the line of work for years now and while he had a few incidents with the first, the latter was something he would never consider to be an issue.
That is until an upcoming pop star came along. Sonic was annoying, smug and the complete opposite to his newly assigned bodyguard.
But you know what they say... opposites attract don't they?

Doppelgänger: A Tale of Two Hedgehogs² by queerwolf79

Summary
Sonic attempts to return to his normal life after the whole Shatterverse fiasco, but his reality flips out in a different way. An alternate dimension Sonic and Shadow wind up in Green Hill, after their villain uses their own version of a Paradox Prism to banish the two hedgehogs.
What is even more strange, besides having another Sonic and Shadow around, is just how different they are. Bizarro Shadow is a cocky and optimistic hedgehog with super speed, and Bizarro Sonic is a grouch and their universe’s Ultimate Lifeform. Just to make things all the more complicated and confusing, their Bizarro twins are apparently a couple.
After Sonic convinces Shadow to retrieve the Prism to help their doppelgängers return home, while Tails is about to test out his newly invented dimension portal device, an argument causes Sonic and Shadow to end up in their doppelgängers’ universe. Now Sonic and Shadow are stuck together in an unfamiliar world with an unhinged villain, and no way to get back home.
And what’s worse? Neither Sonic nor Shadow can get the fact their doppelgängers are dating out of their heads. Who would have thought traversing the Shatterverse was the less confusing situation?
