"Sonic the Hedgehog" (also known as Sonic.exe) is the secondary antagonist of the Sonic Fear series created by yesmen10. He starts as the main protagonist of the first game, but eventually becomes the secondary antagonist of Sonic Fear The Tails Doll, Sonic Fear 2: Metal Sonic Out of Control and Sonic Fear 3: The Apocalypse. He was originally an illusion variant of Sonic used by Tails Doll to torment the hero before being brought into reality by Tails Doll and becoming his right-hand man.


Sonic Fear The Tails Doll

Sonic.exe appears as the starting protagonist of the game in the illusion world created by Tails Doll to torture Sonic. After crashing down from the Tornado due to Metal Sonic he finds himself in a wasteland full of blood and spikes. Tails and Knuckles don't survive the crash, as Tails dies standing up from unknown causes and Knuckles falls onto some spikes below. Sonic then witnesses Amy being flung into a wall of spikes by Metal Sonic. The Tails Doll then starts stalking Sonic, as he finds more of his friends dead, including Shadow and Espio, who the Tails Doll had buried, and even the ghost of Dr. Eggman wondering around near his grave.

Sonic then finds the Tails Doll in an outside area of the zone, who then teleports him into a void, as he inches closer the gravity of the area decreases, causing Sonic to be lifted and dismembered by the spikes above him, as the area fades away and comes back to an open grave for Sonic, as his body parts fall in. The Tails Doll arrives and removes the tombstone, lifting Sonic's body parts into the air and magically reviving him as Sonic.exe, now fully under the Tails Doll's control, as the Tails Doll gives the hedgehog an animal to kill and drops the body into the open grave formerly meant for the hero.

Sonic.exe then appears to travel to the main Sonic's world and hunts down Tails, appearing to him as illusions before teleporting him to a corrupted zone, impaling his head and body to the wall with spikes. He then chases after Knuckles alongside the Tails Doll until they catch him, with the Tails Doll ultimately ripping his head off. Tails Doll then releases Sonic from his illusions and extracts the illusion that is Sonic.exe from Sonic's mind into reality, with the hedgehog then chases the duo off. He finds Sonic.exe and battles him before the two escape, leaving Sonic to die before he is saved by Tails. However, the Sonic.exe and Tails Doll seen were mere apparitions.

Sonic Fear 2: Metal Sonic Out of Control

In the starting level of Sonic Fear 2: Metal Sonic Out of Control (which takes place in the illusion world prior to Sonic breaking out of it, but after he sees all the previous events transpire), multiple duplicates of Sonic.exe appear along with the Tails Doll and Metal Sonic. The zone Sonic is in then becomes corrupted and Sonic jumps into a flashing ball of light.

After the Tails Doll's defeat Sonic.exe teleports Sonic to the Hidden Palace Zone where multiple clones of the demon appear and float around the zone. Sonic.exe occasionally appears to toy with Sonic and begins chasing him near the end of the level. Sonic.exe shows a flashback to where he teleported the illusion variant of Vector to him and killed him with the end of a palm tree. Sonic is teleported to another area where Sonic.exe continues to mess with him and teleports him to another zone with an illusion of Knuckles Sonic tries to follow, but Sonic.exe stops him and a painting appears with the words "Can you stop me?" written in blood. Sonic jumps into the painting and is teleported to another zone where he fights Sonic.exe, who has now grown in size and uses energy balls and falling spikes to try and kill his counterpart. Sonic defeats Sonic.exe and gains the green chaos emerald, he is then transported to Stardust Speedway zone to encounter Metal Sonic.

After the Sonic.exe and Tails Doll apparitions from the first game are defeated in the real world, the real Sonic.exe, Tails Doll and Metal Sonic appear and then fly off as they are chased down by the Sonic Heroes, taking control of the Wing Fortress as Metal Sonic powers up and the three set off. Neo Metal Sonic then turns into Metal Overlord and the Tails Doll and Sonic.exe kidnap Tails and Knuckles. Sonic finds them and turns into Super Sonic, defeating Metal Overlord as he reverts to normal and is teleported to safety by the Tails Doll and Sonic.exe, however he is no longer corrupted.

Sonic Fear 3: The Apocalypse

In the demo version for Sonic Fear 3: The Apocalypse, Sonic.exe and the Tails Doll are stuck within their dimension and plan on once again travelling to Sonic's world using a portal until Sonic arrives. He is held back by an Eggrobo and Metal Knuckles as they activate the portal, allowing Sonic.exe and Tails Doll to come through and start chasing Sonic and eventually teleport themselves to parts unknown. Within this time, Sonic.exe and Tails Doll manage to conquer a large portion of the world, slaughtering innocents left and right.

Eventually, Sonic.exe kidnaps Tails and holds him captive, forcing Sonic to fight him. Once he is beaten, Tails Doll bestows his powers to Sonic.exe, turning him into a giant. However, Sonic manages to defeat Sonic.exe, finally killing him and erasing him from existence.


As Sonic.exe symbolizes how Sonic sees his death at the hands of Tails Doll, Sonic.exe is a bloodthirsty, anarchistic, cruel, sadistic, treacherous, and diabolical monster, mentally breaking, stalking, and confusing his victims before viciously killing them in horrific ways. Although he originated from a false world of illusions and was merely a though-form/projection of how Sonic saw how death by Tails Dolls' hands, Sonic.exe was once the hero of his dimension, but all of that changed once the Tails Doll took control of him, turning him into an obedient "friend" for him to use in his schemes. Sonic.exe is smart and adaptive, utilizing strategies on how he can take down his victims and plot his next moves.

Powers and Abilities

Sonic.exe is able to run at phenomenal speeds and is highly skilled in combat and stealth. Sonic.exe can also fly, levitate, teleport from different areas, and change his size to be as big as he wants. Sonic.exe is also able to make duplicates of himself to pose as him, can use telekinesis to move objects with his mind (primarily in battle), and can shoot energy balls from his hands.
