Unit is a extremely tall robot built of extremely durable metallic alloys of silver color. He doesn't have a face, and as such, doesn't have any humanoid physical feature in the "head" (i.e, no eyes, mouth or ears), despite still having a body resembling an humanoid one. By being a robot, he does not have any kind of clothing. Some notable details in his body includes his name being written in his "shoulder pads" and his initials in the left side pectoral.
