Sonic.exe

Everything About Fiction You Never Wanted to Know.
HYPER-REALISTIC
"This Sonic was a monster, a pure evil, sadistic, all-powerful, nightmarish, demented monster... and all of his victims, including Tails, Knuckles, Robotnik and possibly Kyle, are just his little toys, and the game is the very gateway into his chaotic, nightmarish world and the very Hell his victims are trapped in."
—Tom

Originally published on the Fandom Creepypasta Wiki, it was moved to the Trollpasta Wiki.

The story inspired many clones and fan game recreations, the most notable one was created by MY5TCrimson, available on Game Jolt and itch.io. A fan-made spin-off to the story, Sally.exe, was also made into a game by MY5TCrimson.

An official sequel, Round 2, was published in 2013. An unfinished remake of the story by the same author was published in 2017.
