Carlos is one of Nina's childhood best friends seen in Nina's World. He is African-American and a Latino from Colombia.
- "Hi, I'm Carlos! I'm one of Nina's best friends. You can catch me on the soccer field learning new skills from my brother, Nico. He's deaf, so I normally speak to him in sign language. It's so cool! Sometimes it feels like we have our own secret language. I love going on adventures with him and Nina."
