Appearance: Xenophanes looks very similar to Sonic, but with striking differences. His fur is darker, his arms appear "softer," and his muzzle is completely black, fixed in an unnatural smile. His most defining feature is his black eyes with tiny reddish pupils; a pinkish blood-like substance leaks from his lower eyelids, leaving permanent stains on his face. His body is often depicted as slimmer or flatter. Sonic.EXE is just as fast as the original Sonic.

Appearance: Majin resembles a standard Sonic but is entirely pale blue, with a distorted, human-like face fixed in a constant grin. He wears blue shoes instead of the usual red ones. Additionally, he appears to have no ears.

Appearance: He shares the yellow fur and upturned quills of Classic Super Sonic, but his eyes feature red and white spirals instead of normal black irises. His fur is slightly disheveled, and his teeth are sharper. Personality: He is dark, reckless, bloodthirsty, and sadistic. Fleetway Super Sonic fires red beams from his eyes. He is even faster than Sonic.EXE.

Appearance: Fliqpy looks like a small green bear in a military uniform and dog tags with yellow eyes, but with a much more aggressive expression. His uniform differs slightly from the original design, lacking the dog tags in some iterations. He wears dark green pants and holds a walkie-talkie in his left hand and a knife in his right. Personality: A dark, bloodthirsty entity who kills anything that moves in brutal and creative ways depending on his surroundings. As Fliqpy, he suffers from the delusion that he is back at war facing enemies, leading him to kill indiscriminately.

M is pale, short, stocky, and slightly overweight. His large eyes have tiny red pupils set against pitch-black sclerae. He has a large bulbous nose and a thick brown mustache. He possesses sharp, pointed teeth and a pitch-black tongue that can extend slightly. M has short brown hair with two sideburns and four short tufts of hair pointing upward at the back of his neck. Blood leaks from his eyes and mouth. He wears a red long-sleeved shirt and blue overalls with yellow buttons. He wears a red cap with a red "M" symbol on a white patch, brown shoes, and white gloves with blood on the fingers. He also wields a bloody meat cleaver.

Eteled is a Mii with a bald head, pale skin, large eyes, a large mouth, and a small nose. He wears a black turtleneck sweater and black pants. Unlike Matt, he has arms, though his hands are spherical. His pupils are enlarged, he wears a wide grin, and he carries a fire axe in his left hand. At certain points, his eyes turn completely black.
