Carmen is the mother of Alexandra. She looks identical to her daughter, just older (her appearance was changed after "Mommies Dearest" and "Alex Gets Schooled", as she originally had reddish brown hair with more layers and also had a darker skin tone). Carmen loves her daughter very much, but her main objective and focus is for Alex to get a boyfriend.
In "Alex Gets Schooled" her parents enroll her at Dorsal Academy in England after it was assumed that Alex had gotten straight F’s on her report card (although it later turned out that Alex had gotten A’s and B’s and it turns out that Mandy was actually the one who had gotten straight F’s)
In "Totally Busted", she comes home from Europe along with Samantha and Clover's mothers', Gabriella and Stella, and they find out that their daughters are undercover super spies for WOOHP. They make their daughters quit (Carmen feels that finding a boyfriend for Alex is more important); but they get kidnapped by Mandy, Dominique, and Caitlin at The Groove after they get turned into spy-ssassins because of the SUDS. After their daughters save them, they (Alex, Sam, and Clover) get captured by Mandy, Dominique, and Caitlin. Carmen, Gabby, and Stella turn to Jerry Lewis for help and become spies to save their daughters, and in the end they become official spies for WOOHP (Carmen's Catsuit was royal blue).
- Carmen's voice actress, Katie Leigh (Connie Kendall from Adventures in Odyssey) also voices Alex.
- In "Totally Busted", Carmen's hairstyle resembles Alex's future self in "Futureshock!".
