Sonic.exe is almost identical to the original Sonic, but there are some standouts. Its fur is darker, it wears black and has patches of red or grey. When he smiles, his mouth widens unnaturally, revealing yellow, pointed teeth. Its eyes are pitch black with two bright red dots like irises and very small pupils. Unsurprisingly, Exe always seems to have blood under his eyes, even when he's dead. This is actually a big birthmark because his eyes hurt so much when he was born. Aside from his blood, he also has a slight but visible redness under his eyes from crying excessive amounts of blood.
