redSon looks akin to an average human teenager. He has red hair tied into a high ponytail, a section of it stands up at his widows peak with a yellow highlight resembling fire. He also has a 'X' shaped scar on his right cheek and a red dot on his forehead. Red wears pince-nez glasses, a red long-sleeved trench coat that is torn at the ends over a black shirt, metal-toed indigo shoe-pants with a fuchsia belt, silver buckle, and orange suspenders that rest at his hips.
