X, using Sonic's form, appears as an anthropomorphic hedgehog with blue fur that covers most of his body, peach skin only seen on his stomach, arms, eyelids, inside of ears, and lower half of his head. He has green eyes, six long quills on the back of his head and two triangular ears. He wears white gloves and red boots with white cuffs around the ankles and white straps across the top. It looks like he was disguised into sonic hedgehog's form. But it didnt happen anything wrong when you meet him, so, he looks like he seems you there and smiles. And he quickly goes into your direction, but you still doesnt know he was in his X form. Wow! I gotta say, you kept pace really well there bud! I knew you had it in you! Just got one question. DO YOU WANT TO PLAY WITH ME?

X, better known as Sonic.exe, is the titular main antagonist of JoeDoughBoi's 2023 remake of the original Sonic.exe game, now known as SONIC 2011.
Interdimensional entity with a knack for playing games; he has donned the appearance of Sonic The Hedgehog to get closer to his targets.
2011 X is a sadistic, genocidal entity born from accident in the void during a cataclysm of primordial energies. X has an intense obsession with Sonic The Hedgehog, invaded his world and made him witness his friends being murdered while he can’t do anything. X is on a quest to rule the human race, and has his own cult that creates discs of a game that serves as a portal to his world and the real world. X scales from Multi-Galaxy to Universal and possibly beyond.
