Like Tina and Luci, Carlos and his little brother, Juan, who was played by Michael Krost, are of Mexican descent. Even though he and Juan are brothers, they are only seen together in two episodes of Season 3; "If the Shoe Fits..." and "Any Way You Slice It", both of which Min appeared in. He also has a cat named Fluffy and a bowl of goldfish (named Super, Dee, and Duper; a pun on Barney's famous phrase) for pets as seen in "Our Furry Feathered Fishy Friends".
Carlos lives with Juan, his mother, and his father. His grandmother was mentioned in the episode Room for Everyone. In that same episode, Carlos painted a picture of himself and his family.
