Sonic.exe.

Powers and Abilities: As shown from the original story, Sonic.EXE is able to fly and levitate off the ground, teleport from place to place in a cloud of black smoke, travel through the game and manipulate its code, create dark, ghostly illusions in order to confuse and torment his enemies, and shape-shift in order to look exactly like his idol Sonic. In the second story, he's shown to be highly manipulative and charismatic, able to lead an entire cult to believe he is doing good for the world.

Appearance: Sonic. Exe is able to twist and alter reality in any way he likes, he is completely omnipotent and immortal, and cannot be killed by normal means, but cannot last too long in the real world, which would presumably kill him for good. Exe is also able to create and manipulate dark matter, the very substance he's made of, and wields a large black hole inside his mouth that he uses when he gets bored of a slave, which would completely evaporate their soul and erase them from existence. onic.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 unkempt, 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). Exe's mouth is often unnaturally wide when he smiles and it's always fanged and yellow (Sir JC explained that the yellow on his teeth is not a result of tooth decay but one of the few side effects when his body was first made), and his eyes are pitch black, with two glowing red dots as irises with very tiny pupils.

For some reason, Exe seems to always produce blood under his eyes even when he's not actually crying, though this is a major birthmark (when he was born, Exe's eyes hurt greatly). When Exe isn't crying blood, one can see a faint but noticeable rash under his eyes from crying so much blood.
