Sony appears as a dark indigo, fluffy but messy hedgehog with a black, hollow, and empty mouth from which blood and ink drips to his chin. He wears dark gray gloves and has an inky tentacle piercing through his stomach then to his chest,, beyond his control. Additionally, he sports dirty white shoes and socks. Standing at 3'1", Sony barely displays emotion, often communicates through mumbling, silence, or subtle body language cues. He lost a left leg, twisted right arm and mostly bleeding.
