Summary
There's a strange pull or a perilous pressure that's been collectively felt by the Hero of Mobius. Dr. Eggman has been silent for three years straight, there's been a recent terrorist attack by a group called the Jackal Squad, and there's been mysterious appearances of an unknown stranger lurking around Mobius. These three things will spark a cataclysmic event that multiple realities would never see coming. In due time, Sonic and Shadow will realize that they're far more special than they ever imagined. They will also see just how crucial their relationship is to each other, and how far they're willing to go to prove that they belong together.

Summary
Sonic the Hedgehog, a franchise with plenty of debated Eras and even more Continuities, some far more dangerous then others for an isekai victim as human as the egg-headed main antagonist himself with no super-intelligence or cheats or systems to speak of. Just meta-knowledge, lots of it, and by extension, plenty he can do with it.
Sonic Films? Fine. Sonic X, Boom, and Prime? Manageable. Gameverse? Dicey, but doable. Archie and Fleetway Comics? No thanks. Sonic SatAM and Underground? Better than dealing with any EXEs, still wouldn’t even if his second life depended on it. Shame that he has no choice in the matter.
At least he can decide what to do after the fact, make the most of this situation he’s stuck in. So what to do then? Join GUN? As if. Go the Chris Thorndyke route? Pass. Babysit the cinnamon roll-haired hologram that got carried along for the ride? Meta supposes that, exploiting plot holes aplenty, and causing chaos for all things canon will have to do.

Summary
“The train headed for the Mystic Ruins will now be departing soon.”
A navy blue hedgehog found a vacant seat. Her quills are long, falling past her shoulders and dyed purple at the tips. She wore a plain white t-shirt with a little picture of a chao on it paired with purple shorts that matched her quills. She sighs, and pulled out a weathered old beige book with the word ‘memories’ on its cover in crude handwriting. She flipped through pages; flipping through family photos and the faces of her friends.
On the page after that one, a paper clip bound a missing poster to the book. It’s torn, stained, crumpled, ripped and outdated; the name on it wasn’t even accurate anymore. The picture, however, stayed intact. It showed a young blue hedgehog; so young His quills were closer to aquamarine, His eyes still black and His vocal chords non-functioning.
...
Sonic The Hedgehog's sister is looking for him. Little does she know, an all-powerful god with his face just broke out of it's prison and is plunging the world into meaningless chaos. Teaming up with her childhood friend, can they fill her brother's shoes and save the multiverse?

Summary
“'I wouldn’t be your personal guard if I killed you. I’d rather die first than fail.'
"The king paused, soaking in Amy’s features. His next words hit Amy in the heart: 'Next time kill me.'
"Her emerald eyes widened, taking in a shaky breath. 'What?'
“'That’s my order,' the king stated, his eyes firm with his decision. 'If I’m about to kill you, you kill me, understood?'”Amy Rose pushed her way through her knighthood, proving her to those around her that she was capable of greater things and more. Now she finds herself faced with joining the Royal Guard, held for the elite of the elite, secluded in the most illusive part of the castle. Rumor has it that you work closely with the king: someone that has no face nor name, only a title.
As Amy finds herself in a new life, she is shoved into the profession that no knight had ever been bestowed upon before: the king's personal guard. The job is intimate—yet isolating. Secrets shroud the king. Amy uncovers them bit by bit, but as she realizes how deep she has dove, she finds herself in the same nebulous situation as the king;
She also begins to see how similar their lives are despite the two different worlds they have lived. -
