Biting your lip, you gave him a somber look. "I will come back." You weren't really sure why you said it. In fact, you didn't think you could stay true to that promise. It sounded like you were reassuring yourself more than him. Nonetheless, a burning spurt of determination throbbed in your chest. Sonic assessed you for a moment before shaking his head.

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.

Just a bunch of ol one shots. Enjoy this mess of Fluff, Angst, and Smut. BORIS IS 18! In this book no matter what Boris will be depicted as 18. He is a FICTIONAL character and so I have the right to age him up just as Rouge had the right to age him down in the comics. He is a legal adult in these and that is final. I do not write children. Ages! Boris: 18 Mugman: 19 Bendy: 20 Cup: 23 Mickey: 26 Oswald: 31 Felix: 32 Sheba: 35 Please request on the request page. I Beg ;^;
