The story of Sonic.exe starts in 2011, when a web user by the name “JC the Hyena” posted a short story to the Creepypasta Wiki that described a disturbing and violent Sonic game his friend supposedly mailed him. ... Eggman are each hunted down and killed by a demonic version of Sonic the Hedgehog.
Answer: Sonic.exe looks exactly like his idol, Sonic the Hedgehog, except there are several noticeable differences to his appearance. Exe's fur and quills are a darker blue and less smooth and more unkept, his skin a sickly pale color, with a black color fading into his forearms, hands, forelegs and feet, symbolizing Exe's dark matter in a way. His claws are sharp and pitch black (though sometimes they're also a bright purple).
