Summary
After Sonic's friends head out on their own solo-journeys and Dr. Eggman decides to retire, Sonic struggles to find a new purpose in his life during these times of peace and loneliness. Desperate for distractions, he starts seeking out thrill and getting into one mess after another until he eventually ends up back on Starfall Islands while stalking a shady group of "treasure hunters". Due to a series of unforseen events, the whole group gets involved in a major explosion, with Sonic becoming it's sole survivor.
The hero once again has to deal with being injected with Dark Gaia - while the last time it happened, the evil energy was unable to breach his mental defenses - but a fragile state of mind and years worth of unresolved issues which have all built up ever since then make this an entirely different case.
The weight of the past will eventually catch up even to the fastest thing alive.

Summary
Sonic recently came back from the Starfall Islands. With all his friends gone on their own adventures, he has to learn how to grow on his own. The memories from past adventures have accumulated, scaring not only his body but his mind. He slowly starts deteriorating, will he ask for help? Or will he suffer alone?
OR
"He clutched his leg, trying to massage the cramp out for a few seconds, and then finally looked down. Instead of just seeing his leg, on his calf, he saw red and black crawling up his leg. The colors flickered and pixelated his leg, his breath catching at the sight of it. He blinked, and it was gone. Had he just imagined that, or was that really there? Was the corruption back? Had he truly not gotten rid of it all?"

Summary
much like my ultrakill work of the same vein, this fic consists of every sonic the hedgehog related fanfiction i haven't finished at the time of posting this. they probably won't ever BE finished, unless something autistic happens to me, and in that case i will remove the chapter(s) that fic has in this work and post it fully on its own.
it's mostly sonadow, sorry. some movie, some games, some in-between. goes in order of fondness, with the best for last. WHO Cares about good first impressions! please understand, a lot of these are cliffhangers, unintentionally. sorry.
(a couple of these chapters have, within them, multiple chapters. i'll try to make it easy to read.)Series

When Sonic awoke, he could already tell that he won't get out of bed willingly. The fog that clouded over his mind, the phantom pain of cyber corruption, the constant pressure behind his eyes; it was too much.
Too much.

i ripped the flowers from my lungs and the love from my heart by EmmaSmoke

Summary
Sonic awakens after undergoing surgery for Hanahaki. This removal included the plant itself, but also the memories and emotions involved with all the unrequited love (both romantic and platonic) that fed it. This means that Sonic leaves the hospital without knowing who the person he loved or some of his closest friends are.
Without the emotional investment, he doesn't really care. Everyone else in his life, however, are very worried.

Summary
Sonic has been alone dealing with the aftermath of Starfall Islands for a few weeks. He isn’t doing too good, but he refuses to reach out to anyone about the problems he won’t even address himself.
Sonic gets an opportunity to further distance himself from these problems when GUN requests his help with a mission. Although it takes some convincing from the commander himself, Sonic joins…
… as the Phantom Rider. No one other than the commander knows who’s underneath the helmet. Not even Team Dark— who Sonic is assigned to work with on this case— knows.
As they solve the mission together, can Team Dark figure out who they’re working with? Can Sonic keep his identity hidden?
Can Sonic finally face his problems head on?

Or, Sonic as Phantom Rider does a mission with Team Dark, shenanigans and angst ensue
