Carlota's the oldest, and only daughter, of the four Casagrande kids, similar to how Lincoln is the only boy of the eleven Loud siblings (although Lincoln's the middle child and Carlota's the eldest).
Like Leni, Carlota cares about fashion and her appearance; unlike Leni however, she isn't ditzy. She's into makeovers like Lola, and loves to try and get Ronnie Anne to change her appearance. She appears to be a kind person, showing sisterly love towards Ronnie Anne, and is generally friendly around her family, as well as Lincoln, but gets agitated when her brother Carl gets into her cosmetics.
She was also shown to be a charitable person, as she apparently donates clothes she no longer wears. She seems to be good with kids, as she was seen having a good time walking with Carlitos, her youngest brother, and showed eagerness to babysit Adelaide Chang.
Carlota is a plus-sized Latin American teenage girl with two pairs of eyelashes, and long black hair, with some strands styled into a ponytail. She wears golden circular earrings, magenta lipstick, a light seafoam (cyan outside of promotional art) dress with a white collar, two orange bracelets on each wrist, pink socks, and brown boots.
Alexa PenaVega, who voices Carlota, is the real-life wife of Carlos PenaVega, who voices Carlota's cousin Bobby.
"Operation Dad" reveals that she knows a girl who dropped out of school and started wearing a leather jacket after starting to "hang out with the wrong crowd".
