She arrived at the Sanctuary in 2006, she is the sister of Carlos, Claudio and Vitor, but she never met them, as she was sold to the circus as a baby. She is a large, dominant female with a strong personality. She has a habit of walking upright quite often, mostly to show off her size and intimidate. She likes to wear clothes and makes a kind of skirt out of fabrics to walk around the room. She lives with the chimpanzee Martin and, despite her temper, Monica knows how to respect him.
