Carlos has black hair, with some of the strands standing up, and also has thick, black eyebrows. He wears black glasses that have a square frame, a cream long sleeved shirt, a light green sweater, a red necktie, brown pants, and dark brown shoes.
Carlos is a bibliophilic and absent-minded professor. He loves reading books so much, that he does this with other things at the same time. Reading books distracts him from what's happening around him, like he didn't react to Lalo eating the food he's carrying, or on Carl getting injured by a watermelon.
