Ken appears to be a humanoid block of cement with black eyes and gray hair tied into a short ponytail. His body shape is evenly blocky all around his body. His eyes are generally closed and his lips are pulled upwards. His hero costume consists of a sleeveless brown suit that includes yellow stripes, shorts, and an elongated collar.
