Sonic.exe teleports in front of Knuckles with the text 'FOUND YOU' and Knuckles is forced to fight Sonic.exe as Sonic.exe teleports left and right with black smoke surrounding him. Again a static effect will appear and blood will appear under the ground. Right after Tails became Sonic.exe's victim, Knuckles takes the place as a player and runs into Scrap Brain Zone entitled 'YOU CANT RUN'. Suddenly, Sonic.exe appears and the fox tries to run, but cries when he gets caught, and then Sonic.exe appears and kills him with just one claw. The scene later cuts to a level named 'HIDE AND SEEK', where Tails is crying while running in a burning Angel Island Zone. When Tails gets close to him, static/buzzing sounds can be heard/seen. Eventually, Sonic.exe can be seen hiding in one of the trees along with Tails running, then, out of nowhere, Sonic.exe can be seen just standing there as Tails wonders. The player will soon find dead animals on the ground and in the palm trees. First the player plays as Tails, and then he will go to 'HILL', progressing through the level. Sonic.exe plays a major role in the PC/computer/indie game adaption created by Game Jolt user MY5TCrimson, serving as the titular main antagonist. Tom's fate is ambiguous (though the official sequel reveals that Tom committed suicide to escape from the entity using Sonic's likeness).

After the game ended, Tom turned around to find, to his utter horror, a bloodied Sonic plush doll on his bed. This Sonic had bleeding black and red eyes, a very wide grin, and sharp bloodstained teeth. Then, a 'autentic' image of Sonic appeared on the screen, with the words 'I AM GOD!'. Robotnik from the file select screen and continued with the game.ДЄt the end of the level, Sonic teleported in front of Robotnik, before the screen cut to red static. However, his rest was plagued by nightmares featuring the corrupted Tails and Knuckles, and the demonic Sonic, with him waking in a cold sweat. After playing as Knuckles and losing a supposed 'boss battle' with Sonic, with Knuckles dying the same way as Tails, Tom decided to take a break from the game. Shocked, Tom reads the next message, 'YOU'RE TOO SLOW. Tails screams as his throat is slit a splash of blood is seen coming from his neck.

Do you want to play with me?' In the next level, 'HIDE AND SEEK', Tom witnessed Sonic chasing Tails, the former flying despite an inability to do so without a Super form, before disappearing, teleporting in front of the distraught fox and killing him and cutting to black. When Tails attempted to get his attention during a cutscene by tapping him on the shoulder, Sonic's eyes opened, identical to the evil Sonic on the title screen before cutting to black, with the message 'Hello. Ignoring his friend's warnings, Tom played the game and began to encounter odd, somewhat disturbing phenomena, from a title card featuring an evil-looking Sonic with bloody eyes and glowing pupils with a wide smile to the presence of a file select screen similar to that of the one in Sonic the Hedgehog 3, with a red background and chilling music playing.ДЄs he picked the only available character Tails and began the first stage titled 'HILL ACT 1', Tom continued to find more evidence that there was something wrong with the game, namely the copious amounts of dead animals, all murdered in gruesome ways and eventually encountering Sonic at the end of the level, standing completely still and with his eyes closed. He then proceeded to recount his experience, saying how he received a CD and an accompanying letter from his friend Kyle, begging him to destroy the disc before it's 'too late' and not to never play the game. He claimed that he had not played any glitched or hacked games before, though he admitted that he did not want to after an experience he had.

The original Sonic.exe story centers on Tom, a young man who was a big fan of Sonic the Hedgehog, especially the older games. He escaped his birth place and created a world molded around the levels in the video games and started to scheme his plan of world domination. His first laugh (a la Kefka) gave the world the indication that this creature was evil incarnate. The entity floated around the void for a while until he found a window to both the human world and Sonic's world, in which he became fascinated with Sonic and shaped his body to match his idol's appearance to store his energy. X was accidentally created in the void during a cataclysm involving multiple forms of primordial energy, indirectly creating a sentient mass of dark matter with two red eyes.
